    JORDAN, Circuit Judge.
    This appeal lies at the confluence of intellectual
    property and antitrust law. Following the Supreme Court’s
    decision in FTC v. Actavis, Inc., 
    133 S. Ct. 2223
    (2013), we
    are tasked with balancing a patent owner’s right to exclude
    and the public’s right to benefit from fair and open
    competition.
    The Appellants in this case are the direct and indirect
    purchasers of Wellbutrin XL, a drug designed to treat
    depression.     (Consolidated Brief of Appellees/Cross-
    Appellants (“Ans. Br.”) 6, 19.)         The direct-purchaser
    Appellants bring claims under federal antitrust law, alleging
    that the Appellee, GlaxoSmithKline (“GSK”), 1 violated
    Sections One and Two of the Sherman Antitrust Act by
    entering into an unlawful conspiracy with a company called
    Biovail, 2 GSK’s partner in the development of Wellbutrin
    XL, to delay the launch of generic versions of the drug.
    (Consolidated Brief of Direct Purchaser and End-Payor Class
    1
    “GlaxoSmithKline,” or “GSK,” refers collectively to
    SmithKline Beecham Corporation and GlaxoSmithKline
    PLC, the producers and distributors of Wellbutrin XL.
    2
    “Biovail” refers collectively to Biovail Corporation
    (n/k/a Valeant Pharmaceuticals International, Inc.) and
    Biovail Laboratories International SRL (n/k/a Valeant
    International Bermuda). Biovail was originally a defendant in
    the case but settled with the Appellants prior to the appeal.
    11
    Plaintiffs-Appellants (“Op. Br.”) 2; JA 11465-68.) The
    indirect-purchaser Appellants assert similar theories, but
    under state, rather than federal law. They also allege that
    GSK’s actions violated common law principles and state
    statutes mandating fair trade practices.
    According to the Appellants, GSK is liable under two
    theories. First, the Appellants claim that GSK delayed the
    launch of generic versions of Wellbutrin XL by supporting
    baseless patent infringement suits and a baseless FDA Citizen
    Petition aimed at generic drug companies. Second, they
    claim that GSK delayed the launch of those generic drugs by
    entering into an unlawful reverse payment settlement
    agreement with its potential competitors. 3 The District Court
    granted summary judgment on the merits to GSK with respect
    to both of those theories. It concluded that there was
    insufficient evidence that GSK’s patent litigation was a sham
    or that the settlement delayed the launch of generic versions
    of Wellbutrin XL. At the same time, the Court granted
    GSK’s Daubert motion to exclude the testimony of the
    Appellants’ economic expert. The Court also granted a
    motion to decertify the indirect-purchaser class for lack of
    3
    Ordinarily, when a plaintiff sues a defendant, one
    expects that, if there is a settlement, it will involve a payment
    from the defendant to the plaintiff. A so-called “reverse
    payment” settlement takes place when the plaintiff settles the
    case by paying the defendant. See FTC v. Actavis, Inc., 
    133 S. Ct. 2223
    , 2227 (2013) (“Because the settlement requires
    the patentee to pay the alleged infringer, rather than the other
    way around, this kind of settlement agreement is often called
    a ‘reverse payment’ settlement agreement.”).
    12
    ascertainability and dismissed the indirect-purchaser claims
    brought under the laws of any state that was not the home of a
    named class representative. 4 Finally, the Court denied a
    motion filed by Aetna, Inc. to intervene on the side of the
    indirect purchasers. 5
    4
    The District Court had certified both the direct-
    purchaser and indirect-purchaser classes in August 2011. The
    indirect purchasers allege antitrust claims under the laws of
    Arizona, California, the District of Columbia, Florida,
    Hawaii, Iowa, Kansas, Louisiana, Maine, Michigan,
    Minnesota, Mississippi, Nebraska, Nevada, New Mexico,
    North Carolina, North Dakota, South Dakota, Tennessee,
    Utah, Vermont, West Virginia and Wisconsin. They assert
    violations of consumer protection laws in Alaska, Arizona,
    Arkansas, California, Colorado, Connecticut, Delaware,
    Florida, Georgia, Hawaii, Idaho, Illinois, Kansas, Louisiana,
    Maine, Maryland, Massachusetts, Michigan, Minnesota,
    Missouri, Montana, Nebraska, Nevada, New Hampshire, New
    Mexico, New York, North Carolina, North Dakota, Ohio,
    Oklahoma, Oregon, Pennsylvania, Rhode Island, South
    Carolina, South Dakota, Texas, Utah, Vermont, Washington
    and West Virginia, as well as the District of Columbia. The
    District Court concluded that the indirect-purchaser
    Appellants only have standing to bring their claims under the
    laws of states where their members reside – that is,
    California, Florida, Illinois, Nevada, New York, Ohio,
    Pennsylvania, Tennessee, Texas, and Wisconsin.
    5
    Aetna, an insurance provider, had purchased brand
    and generic versions of Wellbutrin XL in all 50 states. It
    sought to intervene in order to save the indirect purchasers’
    claims from dismissal.
    13
    This appeal followed. Both the direct-purchaser and
    indirect-purchaser Appellants seek review of the District
    Court’s summary judgment and Daubert rulings. The
    indirect-purchaser Appellants also contest the order
    decertifying their class and the denial of Aetna’s motion to
    intervene. GSK filed a conditional cross-appeal challenging
    on numerosity grounds the certification of the direct-
    purchaser class. GSK filed a second conditional cross-appeal
    with respect to the indirect-purchaser class, asking that, if we
    were to disagree with the District Court’s decertification on
    ascertainability grounds, we nevertheless affirm on
    numerosity grounds. The direct-purchaser and indirect-
    purchaser Appellants filed a joint brief addressing the
    summary judgment orders and the order denying Aetna’s
    intervention; the indirect-purchaser Appellants also filed a
    separate brief addressing the decertification order.
    We agree with the District Court’s conclusions that the
    Appellants have failed to establish a genuine dispute of fact
    either as to whether GSK engaged in sham litigation or
    whether GSK’s actions delayed the launch of any generic
    version of Wellbutrin XL. Consequently, we will affirm the
    District Court’s grant of summary judgment and do not reach
    the remaining issues on appeal.
    I.     Background
    A.     The Hatch-Waxman Act
    14
    To better explain the antitrust issues in this case, we
    first describe the regulatory scheme that governs the testing
    and approval of new drugs in the United States. That
    framework was established by the Drug Price Competition
    and Patent Term Restoration Act of 1984, 98 Stat. 1585, as
    amended, which is commonly known as the Hatch-Waxman
    Act (“the Act”), or simply Hatch-Waxman. Actavis, 133 S.
    Ct. at 2227-28.
    A drug manufacturer seeking to market a new drug
    “must submit a New Drug Application [(NDA)] to the federal
    Food and Drug Administration (FDA) ... and undergo a long,
    comprehensive, and costly testing process, after which, if
    successful, the manufacturer will receive marketing approval
    from the FDA.” 
    Id. at 2228
    (citing 21 U.S.C. § 355(b)(1)).
    One of the goals of Hatch-Waxman is to increase competition
    between generic and brand-name drugs. To that end, the Act
    allows the manufacturers of generic drugs to obtain FDA
    approval without having to endure the gauntlet of procedures
    associated with NDAs.
    [O]nce the FDA has approved a brand-name
    drug ... a manufacturer of a generic drug can
    obtain similar marketing approval through the
    use of abbreviated procedures. The [Act]
    permits a generic manufacturer to file an
    Abbreviated New Drug Application [(ANDA)]
    specifying that the generic has the “same active
    ingredients as,” and is “biologically equivalent”
    to, the already-approved brand-name drug. ...
    [B]y allowing the generic to piggy-back on the
    pioneer’s approval efforts, [the Act] “speed[s]
    15
    the introduction of low-cost generic drugs to
    market,” thereby furthering drug competition.
    
    Id. (last alteration
    in original) (internal citations omitted)
    (quoting Caraco Pharm. Labs., Ltd. v. Novo Nordisk A/S, 
    566 U.S. 399
    , 405 (2012)).
    In addition to streamlining the drug approval process,
    the Hatch-Waxman Act provides specialized procedures for
    brand-name and generic drug manufacturers to resolve
    intellectual property disputes. The Act “requires the ... brand-
    name manufacturer to list in its [NDA] the number and the
    expiration date of any relevant patent. And it requires the
    generic manufacturer in its [ANDA] to assure the FDA that
    the generic will not infringe the brand-name’s patents.” 
    Id. (internal quotation
    marks and citations omitted). One way for
    generic manufacturers to make that assurance is to “certify
    that any listed, relevant patent ‘is invalid or will not be
    infringed by the manufacture, use, or sale’ of the drug
    described in the [ANDA].”            
    Id. (quoting 21
    U.S.C.
    § 355(j)(2)(A)(vii)). That assurance is referred to as a
    paragraph IV certification. 
    Id. To facilitate
    the filing of
    infringement suits, a paragraph IV certification
    “automatically counts as patent infringement.” 6 
    Id. (citation 6
             The “infringement” in those circumstances is a legal
    construct that permits a patent holder to initiate suit without
    having to wait for the generic manufacturer to actually make,
    use, or sell a generic version of the patented drug. Eli Lilly &
    Co. v. Medtronic, Inc., 
    496 U.S. 661
    , 678 (1990) (explaining
    that “the defined act of infringement [is] artificial” and exists
    to “enable the judicial adjudication upon which the ANDA ...
    scheme[] depend[s]”). Because a paragraph IV certification
    16
    omitted). Hatch-Waxman further states that “[i]t shall be an
    act of infringement to submit an [ANDA] for a drug claimed
    in a patent[.]” 35 U.S.C. § 271(e)(2)(A).
    The Act also encourages brand-name manufacturers to
    file patent infringement suits quickly. If a patentee files an
    infringement suit against a generic manufacturer within 45
    days of receiving notice of the filing of a paragraph IV
    certification, the patentee is rewarded with some breathing
    space before competition can begin: the FDA is required to
    withhold approval of the generic drug for 30 months or until
    the infringement case is resolved, whichever comes first. 21
    U.S.C. § 355(j)(5)(B)(iii).
    Finally, the Act “provides a special incentive for a
    generic to be the first to file an [ANDA] taking the paragraph
    IV route.” 
    Actavis, 133 S. Ct. at 2228-29
    . The first applicant
    is entitled to an exclusivity period during which no generic
    drug other than the first-filer’s can compete with the brand-
    name drug. More specifically, the Act prohibits the FDA
    from approving any ANDA other than the one first filed until
    180 days after the first-filer starts marketing its drug.
    21 U.S.C. § 355(j)(5)(B)(iv). In effect, that allows the first-
    filing generic to exclude other generics from the market for
    is defined as a technical act of infringement, it allows a patent
    owner to sue, but it does not speak to whether the disclosed
    generic drug does, in fact, infringe the cited patent. Glaxo,
    Inc. v. Novopharm, Ltd., 
    110 F.3d 1562
    , 1569 (Fed. Cir.
    1997) (“The occurrence of the defined ‘act of infringement’
    does not determine the ultimate question whether what will be
    sold will infringe any relevant patent.”).
    17
    longer than 180 days because it may delay or decline to
    launch its drug. 7
    B.      Factual and Procedural Background
    In 1985, GSK obtained FDA approval for bupropion
    hydrochloride, a drug for the treatment of major depressive
    disorders. The drug became branded as “Wellbutrin.” Over
    the years, several companies, including GSK, sought to
    develop an extended release formulation of bupropion
    hydrochloride. While GSK was unsuccessful, at least two
    companies – Biovail and Andrx Pharmaceuticals, LLC –
    found success and obtained patents covering extended release
    7
    While the exclusivity period can be forfeited if the
    first-filer fails to market its drug, it can take time to trigger
    the forfeiture. “Forfeiture applies only upon the satisfaction
    of two statutory conditions. The first condition [(i.e., the
    failure to market the drug either within 75 days of the date the
    ANDA was approved or within 30 months of the date the
    ANDA was submitted, whichever comes earlier)] is relatively
    easy to satisfy. The second is triggered only if an appeals
    court rules that the relevant patents are invalid or not
    infringed, or if a settlement reaches a similar result.” C. Scott
    Hemphill, An Aggregate Approach to Antitrust: Using New
    Data and Rulemaking to Preserve Drug Competition, 109
    Colum. L. Rev. 629, 660-61 (2009) (footnotes omitted). That
    rule “allows first-filers to retain their exclusivity by settling.”

    formulations of the drug. 8 To gain access to an extended
    release formulation, GSK obtained an exclusive license to
    certain of Biovail’s patents. Then, in August 2002, GSK filed
    an NDA for that new formulation, which was approved the
    following year. The extended release Wellbutrin was named
    “Wellbutrin XL.”
    Between September 2004 and May 2005, four generic
    manufacturers filed ANDAs seeking approval to market
    generic versions of Wellbutrin XL. Each of the four
    companies – Anchen, Abrika, Impax, and Watson – filed a
    paragraph IV certification. 9 Of those companies, Anchen was
    the first to file its ANDA, and, as a result, was entitled to the
    180-day period of exclusivity.
    Biovail filed patent infringement suits against all four
    generic companies. With one exception, it filed its several
    suits within 45 days of receiving each of the would-be
    8
    Biovail obtained U.S. Patents 6,096,341 and
    6,143,327 (the ’341 and ’327 patents), while Andrx obtained
    U.S. Patent 6,905,708 (the ’708 patent). At the time that
    Biovail and Andrx were conducting their research, it appears
    that most or all of the information relating to bupropion
    hydrochloride and its delivery mechanisms was in the public
    domain. Neither Biovail nor Andrx needed to obtain a license
    from GSK in order to conduct its research.
    9
    The companies’ full names are Anchen
    Pharmaceuticals, Inc., Abrika Pharmaceuticals, LLP, Impax
    Laboratories, Inc., and Watson Pharmaceuticals, Inc.,
    respectively.
    19
    competitors’ paragraph IV certifications. As explained
    above, that triggered a stay that generally prevented the FDA
    from approving the ANDAs for 30 months, or until the
    resolution of the respective patent suits, whichever came first.
    Biovail did not file suit within the required 45-day period
    against Impax’s 300 mg dosage of extended release
    bupropion hydrochloride. Impax was therefore not subject to
    the 30-month stay with respect to that product. GSK joined
    Biovail’s suits against Anchen and Abrika but not the suits
    against Impax and Watson. 10
    In addition to its lawsuits, Biovail filed a “Citizen
    Petition” with the FDA on December 20, 2005. 11 Biovail
    asked the FDA to impose certain requirements for approval of
    any generic version of Wellbutrin XL. The FDA issued a
    final response to the Petition in December 2006, granting it in
    part and denying it in part.
    On December 21, 2005, Andrx filed suit against GSK,
    alleging that Wellbutrin XL, in 150 mg dosages, violated
    Andrx’s ’708 patent, 
    see supra
    n.8. Andrx also filed suit
    10
    GSK’s CEO, Jean-Pierre Garner, explained that
    GSK elected not to join the suits against Impax or Watson
    because it did not believe it would have sufficient control
    over the litigation.
    11
    Interested citizens may “petition the Commissioner
    [of the FDA] to issue, amend, or revoke a regulation or order,
    or to take or refrain from taking any other form of
    administrative action.” 21 C.F.R. § 10.25. GSK elected not
    to join Biovail’s FDA petition.
    20
    against Anchen for infringing the same patent with a generic
    version of Wellbutrin XL. In both cases, Andrx sought
    damages and an injunction against the sale of infringing
    products. In February 2007, all of the parties involved in the
    Wellbutrin-related patent litigation, except for Abrika,
    entered into a settlement. 12
    The next year, in May 2008, this litigation began. Two
    putative classes – a class of direct purchasers (e.g., entities
    like pharmacies that purchased Wellbutrin XL directly from
    GSK) and a class of indirect purchasers (e.g., consumers) –
    filed suits against Biovail and GSK. 13 As noted at the outset
    12
    Abrika settled with Biovail a few months later, after
    GSK had withdrawn from the suit.
    13
    The direct-purchaser class includes “[a]ll persons or
    entities in the United States ... who purchased Wellbutrin XL
    directly from any of the Defendants at any time during the
    period November 14, 2005 through August 31, 2009... .” (JA
    3.) In total, the class contains over 30 members. When
    certified, the indirect-purchaser class included “[a]ll persons
    or entities who purchased an [appropriately FDA- rated]
    generic bioequivalent of Wellbutrin XL ... at any time
    [between November 14, 2005 and April 29, 2011] in
    California, Florida, Nevada, New York, Tennessee and
    Wisconsin; and ... [a]ll entities that purchased 150 mg or
    300 mg Wellbutrin XL before an [appropriately FDA-rated]
    generic bioequivalent was available for such dosages AND
    purchased generic XL in the same state after generic XL
    became available in California, Florida, Nevada, New York,
    Tennessee and Wisconsin.” (Appendix for 15-2875 at 6.)
    21
    of this opinion, both sets of plaintiffs alleged that Biovail and
    GSK conspired to prevent generic versions of Wellbutrin XL
    from entering the market. The instrumentalities of the alleged
    conspiracy were, according to the Plaintiffs, sham lawsuits, a
    sham FDA petition, and an unlawful reverse payment
    settlement. The direct purchasers brought their claims under
    federal law, while the indirect purchasers brought their claims
    under various state laws. Biovail settled with both classes in
    November 2012, so only GSK has remained as a defendant. 14
    The District Court had earlier granted summary
    judgment for GSK on the merits on all of the claims. First,
    the Court granted summary judgment on the sham petition
    claims. Shortly after that, it stayed both the direct-purchaser
    and indirect-purchaser cases while the Supreme Court
    considered potentially relevant petitions for writs of
    certiorari.   The District Court continued the stay in
    anticipation of the Supreme Court’s decision in FTC v.
    Actavis, Inc., 
    133 S. Ct. 2223
    (2013). After the Actavis
    opinion issued, the District Court granted summary judgment
    for GSK on the reverse payment claims.
    The District Court also rendered decisions regarding
    class certification. It at first certified both putative classes.
    Later, however, it concluded that the indirect-purchaser class
    only had standing “under the laws of those states where the
    plaintiffs are located or their members reside.” (JA 243.)
    The Court thus dismissed the claims arising under the laws of
    states that were not represented by one of the named
    plaintiffs. In response, Aetna moved to intervene in the
    14
    The two cases proceeded independently in the
    District Court, but were consolidated on appeal.
    22
    indirect-purchaser suit. It alleged that it had purchased brand
    and generic Wellbutrin XL in all fifty states, and that,
    consequently, its intervention would alleviate the standing
    issues. The Court denied Aetna’s motion. In June 2015, the
    Court granted a motion to decertify the indirect-purchaser
    class on ascertainability grounds.
    Before us on appeal are the following rulings: the grant
    of summary judgment to GSK on all claims, the exclusion of
    the testimony of the Appellants’ economic expert, the
    decertification of the indirect-purchaser class, the dismissal of
    certain of the indirect-purchaser Appellants’ claims for lack
    of standing, and the denial of Aetna’s motion to intervene.
    GSK also conditionally challenges the certification of the
    direct-purchaser class. And, should the indirect purchasers
    succeed in overcoming the ascertainability objection to
    certification of their class, GSK also conditionally appeals
    any certification of that class, citing problems with
    numerosity.
    23
    II.   Discussion 15
    A.     Sham Litigation
    The first broad issue on appeal is whether the District
    Court erred in granting summary judgment on the sham
    litigation claims. The Appellants argue that GSK violated
    antitrust laws by conspiring with Biovail to prosecute sham
    lawsuits against Anchen, Abrika, Impax, and Watson, and to
    file a sham petition with the FDA. According to the
    Appellants, GSK and Biovail worked together to press the
    infringement lawsuits in order to exploit the mandatory 30-
    month stay created by the Hatch-Waxman Act.                The
    Appellants also allege that, but for the lawsuits and the FDA
    petition, the FDA would have approved Anchen’s ANDA
    immediately and likewise would have approved the other
    three ANDAs at the end of Anchen’s 180-day exclusivity
    15
    The District Court had subject matter jurisdiction
    over the direct purchasers’ claims under 15 U.S.C. § 15(a)
    and 28 U.S.C. §§ 1331, 1332, and 1337. The District Court
    had subject matter jurisdiction over the indirect purchasers’
    claims under 28 U.S.C § 1332(d)(2). We have jurisdiction
    over the appeal pursuant to 28 U.S.C. § 1291.
    “We exercise plenary review over a district court’s
    order granting summary judgment, applying the same
    standard as the district court. We will affirm only if drawing
    all reasonable inferences in favor of the nonmoving party,
    there is no genuine issue as to any material fact and the
    moving party is entitled to judgment as a matter of law.”

    period. The assertion is that, without the delay in ANDA
    approvals, Anchen and the other generics would have
    launched their products sooner, resulting in increased
    competition and lower drug prices for pharmacies and
    consumers.
    1.     Applicable Law
    A plaintiff claiming that a lawsuit is, by its very
    existence, anticompetitive and unlawful faces an uphill battle.
    It is well-established that the First Amendment protects the
    right to petition the government and to have access to the
    courts. Prof’l Real Estate Inv’rs, Inc. v. Columbia Pictures
    Indus., Inc., 
    508 U.S. 49
    , 56-57 (1993); 16 Cal. Motor Transp.
    Co. v. Trucking Unlimited, 
    404 U.S. 508
    , 515 (1972); see also
    U.S. Const. amend. I (“Congress shall make no law ...
    abridging ... the right of the people ... to petition the
    Government for a redress of grievances.”). That protection is
    the basis of the Noerr-Pennington doctrine, which holds that
    “[t]hose who petition [the] government for redress are
    generally immune from antitrust liability.” 17 PRE, 
    508 U.S. 16
            We will refer to Professional Real Estate Investors
    v. Columbia Pictures Industries, 
    508 U.S. 49

    throughout this opinion as “PRE.”

    The Noerr-Pennington doctrine “takes its name from
    Eastern R.R. Presidents Conference v. Noerr Motor Freight,
    Inc., 
    365 U.S. 127
    (1961) (holding that railroads’ publicity

    “[A]ctivity ‘ostensibly directed toward influencing
    governmental action’ does not qualify for [first amendment]

    interfere directly with the business relationships of a

    365 U.S. 127
    , 144 (1961)).
    To determine whether a lawsuit qualifies as a “sham,”
    courts apply a two-part test:
    First, the lawsuit must be objectively baseless in
    the sense that no reasonable litigant could
    realistically expect success on the merits. If an
    objective litigant could conclude that the suit is
    reasonably calculated to elicit a favorable
    outcome, the suit is immunized under Noerr,
    and an antitrust claim premised on the sham
    exception must fail.        Only if challenged
    litigation is objectively meritless may a court
    examine the litigant’s subjective motivation.
    Under this second part ..., the court should
    focus on whether the baseless lawsuit conceals
    an attempt to interfere directly with the business
    relationships of a competitor through the use of
    the governmental process—as opposed to the
    outcome of that process—as an anticompetitive
    have federal agency impose higher minimum wage for coal
    suppliers to TVA were immune from antitrust liability).”

    weapon. This two-tiered process requires the
    plaintiff to disprove the challenged lawsuit’s
    legal viability before the court will entertain
    evidence of the suit’s economic viability.

    The Supreme Court has explained that “[t]he existence
    of probable cause to institute legal proceedings precludes a
    finding that an antitrust defendant has engaged in sham
    litigation.” 
    Id. at 62.
    In selecting “probable cause” as the
    standard by which to judge objective baselessness, the Court
    said that it was drawing from “[t]he notion of probable cause,
    as understood and applied in the common law tort of
    wrongful civil proceedings[.]” 
    Id. A litigant
    has probable
    cause to initiate a suit if the litigant has “a reasonable belief
    that there is a chance that a claim may be held valid upon
    adjudication.” 
    Id. at 62-63
    (internal citations, quotation, and
    alterations omitted); see also Restatement (Second) of Torts
    § 675. In other words, the essential question is not whether
    18
    The Supreme Court in PRE indicated that the
    plaintiff in an antitrust suit has the burden of proving that the
    defendant is not entitled to immunity under the Noerr-
    Pennington doctrine. See 
    PRE, 508 U.S. at 61
    (explaining
    that a plaintiff must “demonstrat[e] both the objective and the
    subjective components of a sham”). The Court was silent,
    however, as to the standard of proof (i.e., clear and
    convincing evidence, or preponderance of the evidence)
    needed to show objective baselessness. Because our decision
    in this case does not hinge on the standard of proof, we leave
    that question for another day.
    27
    the suit succeeds, but whether the suit was a sham at the time
    it was filed. See 
    PRE, 508 U.S. at 60
    n.5 (cautioning that
    “when the antitrust defendant has lost the underlying
    litigation, a court must resist the ... temptation to engage in
    post hoc reasoning by concluding that an ultimately
    unsuccessful action must have been unreasonable or without
    foundation” (internal quotations omitted)).
    In addition, it is not enough for a plaintiff to show that
    a defendant engaged in sham litigation. “[A] plaintiff who
    defeats the defendant’s claim to Noerr immunity ... must still
    prove a substantive antitrust violation.” 
    Id. at 61.
    That
    includes proving the challenged lawsuit is “causally linked”
    to an antitrust injury. Brunswick Corp. v. Pueblo Bowl-O-
    Mat, Inc., 
    429 U.S. 477
    , 489 (1977) (describing antitrust
    injury as “injury of the type the antitrust laws were intended
    to prevent and that flows from that which makes defendants’
    acts unlawful”).
    As noted earlier, the Appellants argue that each of the
    patent infringement suits relating to generic versions of
    Wellbutrin XL (that is, each of the suits against Anchen,
    Abrika, Watson, and Impax), as well as the Citizen Petition,
    was an instance of anticompetitive sham litigation or sham
    petitioning that caused antitrust injury by delaying the entry
    of generic versions of Wellbutrin XL into the market. The
    District Court granted summary judgment to GSK with
    respect to each of the five challenged actions. We agree that
    the sham litigation claims fail, for reasons we now endeavor
    to explain.
    28
    2.     The Anchen Lawsuit
    The sham litigation claim relating to the Anchen suit
    fails for the simple reason that an act of infringement plainly
    occurred. The already high hurdle for stating an antitrust
    claim for anticompetitive litigation, 
    PRE, 508 U.S. at 56
    , is
    higher still in the context of an ANDA case because, as
    described above, the Hatch-Waxman Act states that “[i]t shall
    be an act of infringement to submit” an ANDA for a drug
    claimed in a patent, 35 U.S.C. § 271(e)(2). Since the
    submission of an ANDA is, by statutory definition, an
    infringing act, an infringement suit filed in response to an
    ANDA with a paragraph IV certification could only be
    objectively baseless if no reasonable person could disagree
    with the assertions of noninfringement or invalidity in the
    certification. See AstraZeneca AB v. Mylan Labs., Inc., No.
    00-cv-6749, 
    2010 WL 2079722
    , at *4 (S.D.N.Y. May 19,
    2010) (“[A]t the outset of Astra’s case, Mylan gave Astra an
    objectively reasonable basis to sue: Mylan provided Astra
    notice of its Paragraph IV certification.”), aff’d sub nom. In re
    Omeprazole Patent Litig., 412 Fed. App’x 297 (Fed Cir.
    2011). It suffices here to say that this case does not present
    such a circumstance. Anchen filed an ANDA for a drug that
    was claimed in Biovail’s ’341 patent. There is nothing in the
    record indicating that Biovail, the patentee, and GSK, the
    exclusive licensee, 19 were less than objectively reasonable in
    19
    “Because the legally protected interests in a patent
    are exclusionary rights created by the Patent Act, a party
    holding one or more of those exclusionary rights—such as an
    exclusive licensee—suffers a legally cognizable injury when
    an unauthorized party encroaches upon those rights and
    29
    acting on that technical act of infringement, and that alone
    provides a sufficient basis for us to affirm the District Court’s
    grant of summary judgment.
    The content of the ANDA bolsters that conclusion. As
    explained above, Wellbutrin XL used a formulation of
    bupropion hydrochloride described in Biovail’s ’341 patent.
    That patent discloses, among other things, “a core comprising
    bupropion hydrochloride and conventional excipients, free of
    stabilizer” (JA 3117, ’341 patent at 9:50-51 (emphasis
    added).) Anchen’s paragraph IV certification asserted that
    “Anchen’s proposed product cannot be deemed literally to
    infringe [the patent] because it includes a stabilizing amount
    of hydrochloric acid in the core[,]” and thus does not satisfy
    the “free of stabilizer” limitation. (JA 35714); see also
    Pfizer, Inc. v. Teva Pharm., USA, Inc., 
    429 F.3d 1364
    , 1376
    (Fed. Cir. 2005) (explaining that a product must satisfy each
    of a claim’s limitations in order to infringe). But Anchen’s
    ANDA suggested otherwise. It included several tables listing
    the ingredients that would be present in Anchen’s drug, along
    with the relative percentages of each. While the tables listed
    hydrochloric acid, which can serve as a stabilizer, 20 they
    indicated that the acid would compose 0% of the final
    product. To the same effect, the percentages associated with
    the other listed ingredients summed to 100%. As if to
    emphasize that point, the tables explicitly stated that the
    therefore has standing to sue.” WiAV Solutions LLC v.
    Motorola, Inc., 
    631 F.3d 1257
    , 1264-65 (Fed. Cir. 2010).
    20
    Hydrochloric acid is a stabilizing agent. (See
    Anchen’s paragraph IV certification, JA 35714 (referring to
    hydrochloric acid as a stabilizing agent).)
    30
    hydrochloric acid had been “removed” or “evaporated” from
    the drug. (JA 11748-52.) That language provided GSK and
    Biovail with sufficient probable cause to file its infringement
    suit, and no reasonable jury – i.e., no jury considering the
    sham litigation claim – could conclude otherwise. See Abbott
    Labs. v. TorPharm, Inc., 
    300 F.3d 1367
    , 1373 (Fed. Cir.
    2002) (holding that the ANDA specification governs the
    infringement inquiry).
    The parties and the District Court invested
    considerable effort in addressing two subsidiary questions –
    whether FDA regulations required Anchen to quantify the
    amount of stabilizer present in its drug, and whether Biovail
    asserted a frivolous claim construction position. Those
    disputes are ultimately irrelevant. The question here is
    whether GSK and Biovail could have perceived “some
    likelihood of success” in their case at the time of filing. 
    PRE, 508 U.S. at 65
    ; Rohm & Haas Co. v. Brotech Corp., 
    127 F.3d 1089
    , 1093 (Fed. Cir. 1997) (concluding that courts should
    evaluate the question of objective baselessness “in light of ...
    information [available] at the time of filing”). At that time,
    the only information they had access to was an excerpt of
    Anchen’s ANDA – an excerpt that, under a plain reading,
    suggested the non-infringement theory offered in Anchen’s
    paragraph IV certification was, or at least could be, infirm.
    Viewed in that light, the FDA’s rules regarding quantification
    are insufficient to override the probable cause provided in the
    ANDA. Again, the fact that one might conclude, after a
    thorough investigation, that Anchen’s ANDA did not
    definitively exclude the presence of hydrochloric acid does
    not mean it was unreasonable for GSK and Biovail to file
    their suit, as it was not unreasonable for them to take the
    31
    ANDA at face value. 21 Similarly, the fact that a court (in the
    underlying patent litigation) rejected Biovail’s later proposed
    claim construction does not bear on whether the patent
    infringement suit was objectively baseless from the outset. 22
    21
    As explained above, Anchen’s ANDA quantified the
    amount of hydrochloric acid in its drug as “--” and indicated
    that the other ingredients summed to 100%. The Appellants
    argue that, under standard industry convention, “--” denotes a
    residual quantity greater than zero. However, they do not
    point to any evidence showing that GSK and Biovail’s
    interpretation of either “--” or “100%” was unreasonable.
    More to the point, they have not demonstrated that it was
    unreasonable to view the claim language “free of stabilizer”
    as covering a residual amount so small as to not register in the
    tables they provided.
    22
    It is worth noting that GSK withdrew from the case
    well before claim construction began. While it is no doubt
    important to think about possible constructions for patent
    claims before filing a case, it would be unfair to require
    parties to divine the outcome of claim construction before
    filing. That is especially true in the Hatch-Waxman context,
    where many details about the potentially infringing drug
    (details that could shape a plaintiff’s claim construction
    position) cannot be known at the time a suit is filed and where
    there are congressionally designed pressures to file suit
    quickly. See 21 U.S.C. § 355(b)(3)(D) (stating that an ANDA
    applicant is required to provide notice to patentees
    “includ[ing] a detailed statement of the factual and legal basis
    of the opinion of the applicant that the patent[s] [are] invalid
    or will not be infringed,” but refraining from requiring
    ANDA applicants to submit any additional information). The
    32
    See Rohm & Haas 
    Co., 127 F.3d at 1092
    (explaining that
    “[p]atent litigation is complex, long, and difficult” and that
    parties and courts rely on “discovery procedures, partial or
    complete summary judgment, and evidentiary rules to narrow
    the issues”).
    The Appellants also argue that the District Court
    “usurp[ed] the role of the jury” by “find[ing] facts.” (Op. Br.
    53-54.) We disagree. In PRE, the Supreme Court held that
    courts can grant summary judgment on the issue of objective
    baselessness if “there is no dispute over the predicate facts of
    the underlying legal 
    proceeding.” 508 U.S. at 63
    . Here, the
    predicate facts include the content of Anchen’s ANDA. The
    existence of that content – as opposed to its accuracy – is not
    in dispute. Instead, the parties disagree about whether that
    content was sufficient to establish probable cause for the
    time limits imposed by the Hatch-Waxman Act embody a
    “file-now, discover-details-later” policy, and while the merit
    of that policy may make for an interesting debate, Aaron S.
    Kesselheim & Jonathan J. Darrow, Hatch-Waxman Turns 30:
    Do We Need a Redesigned Approach for the Modern Era?, 15
    Yale J. Health Pol’y, L. & Ethics 293 (2015) (describing the
    debate over whether the Act is good policy), it is not our
    place – nor was it GSK’s – to take that debate on. We decline
    to apply the antitrust laws in a way that would undermine the
    operation of Hatch-Waxman.
    It is likewise a painful stretch to say that Biovail’s
    claim construction arguments show GSK was wrong to join in
    the initial decision to file against Anchen. At the time the suit
    was filed, GSK was not obligated to know the details of claim
    construction arguments that Biovail would later present.
    33
    objective baselessness inquiry. 
    PRE, 508 U.S. at 62
    . That,
    however, is a legal question, not a factual one. Highmark,
    Inc. v. Allcare Health Mgmt. Sys., Inc., 
    701 F.3d 1351
    , 1353
    (Fed. Cir. 2012) (“Under PRE, the reasonableness of a legal
    position … is itself a question of law[.]”); Stewart v.
    Sonneborn, 
    98 U.S. 187
    , 194 (1878) (“[P]robable cause is a
    question of law in a very important sense. ... Whether the
    circumstances alleged to show it probable are true, and
    existed, is a matter of fact; but whether, supposing them to be
    true, they amount to a probable cause, is a question of law.”).
    In granting summary judgment, the District Court decided
    that GSK’s suit “[did] not fit the profile of objectively
    baseless sham litigation.” (JA 72, 95.) It was entitled to
    reach that legal conclusion. 23
    There is an additional problem with the Appellants’
    argument that warrants discussion. As we noted earlier, to
    establish an antitrust claim for anticompetitive litigation, the
    Appellants had to show not only that GSK’s litigation was a
    sham, but also that it caused an antitrust injury by delaying
    generic competition. Based on the current record, they would
    have difficulty making such a showing, for at least two
    reasons. First, generic entry would have been blocked by
    Biovail’s continuing litigation against Anchen, in which GSK
    did not participate. Under Hatch-Waxman, the rule requiring
    the FDA to delay approving an ANDA is based not simply on
    the filing of a lawsuit but on the ongoing presence of a
    lawsuit. See 21 U.S.C. § 355(j)(5)(B)(iii) (stating that the
    FDA may approve an ANDA as soon as “the district court
    23
    That the Court elected at times to use the verb “find”
    instead of “conclude” does not change our decision.
    34
    decides that the patent is invalid or not infringed”). GSK
    withdrew from the underlying litigation just a few months
    after the case was filed. Biovail, however, continued to
    pursue the suit. That is significant, as it means that the delay
    in competition based on the lawsuit should likely be attributed
    to Biovail rather than to GSK. 24
    Second, and perhaps more formidably, generic entry
    would have been blocked by the ’708 patent owned by Andrx.
    We address the Andrx patent in more detail in the context of
    the reverse payment settlement.      The implications for
    causation, however, apply just as much to the Appellants’
    sham litigation claims as they do to their reverse payment
    claims.
    24
    GSK and Biovail filed their suit against Anchen on
    December 21, 2004. GSK withdrew from the case exactly
    four months later, on April 21, 2005, long before the 30-
    month stay expired. In order to prevail against GSK, the
    Appellants must show that at least some delay can be
    attributed to GSK’s actions in the case – that is, they must
    show that at least some delay can be attributed to the first four
    months of the litigation. There is no evidence in the record
    indicating that any delay can be linked to that period of time.
    In a heading in their statement of undisputed facts, the
    Appellants state that “GSK Withdrew From the Anchen and
    Abrika Cases But Not the Conspiracy[.]” It takes some
    chutzpah to use that language, as GSK plainly disputes that it
    was ever in a conspiracy with Biovail. We consider the
    conspiracy argument in more detail below.
    35
    3.     The Abrika Lawsuit
    The Appellants contend that GSK and Biovail’s suit
    against Abrika was another instance of anticompetitive
    litigation. As before, they argue that GSK and Biovail are not
    entitled to Noerr-Pennington immunity because the lawsuit
    was a sham. The District Court granted summary judgment
    to GSK based on its conclusion that there was insufficient
    evidence to show that the litigation delayed Abrika’s entry
    into the market. Again, we agree.
    As an initial matter, we note that two of the arguments
    that defeated the Appellants’ claim relating to the Anchen
    litigation also justify affirming the District Court on this
    point. First, Abrika’s ANDA, including the paragraph IV
    certification, provided GSK with an objectively reasonable
    basis to file its suit. 25 Additionally, as in the Anchen case,
    GSK initially joined with Biovail in the infringement suit, but
    then withdrew, and Biovail continued to litigate. That means
    that any delay attributable to the litigation would have existed
    even without GSK’s involvement.
    Moreover, there is an independent problem with the
    causation theory as it relates to the Abrika litigation. The
    Appellants argue that the infringement suit against Abrika
    delayed Abrika’s entry into the market because the suit
    25
    Without parsing the Abrika ANDA in the same
    detail as we did Anchen’s, it suffices to say that the
    Appellants have not provided evidence to demonstrate that it
    was objectively unreasonable for Biovail and GSK to act on
    the technical act of infringement that the ANDA and
    paragraph IV certification provided.
    36
    imposed a 30-month stay on the FDA’s approval of Abrika’s
    ANDA. There is, however, no evidence that Abrika could
    have launched even in the absence of the 30-month stay. To
    the contrary, it is undisputed that the FDA could not have
    approved Abrika’s ANDA until the end of Anchen’s 180-day
    first-filer exclusivity period, a period that would not even
    start until Anchen launched its drug. Thus, it should surprise
    no one to learn that, while the 30-month stay imposed by
    GSK’s suit expired on June 21, 2007, Abrika’s ANDA was
    not approved until over a year later, after Anchen’s
    exclusivity period came to an end. In responding to those
    facts, the Appellants in their Reply Brief appear to abandon
    their argument that it was the Abrika lawsuit that caused
    delay. Instead, they argue that the delay was caused by the
    suit against Anchen. That argument, however, is unavailing
    for the reasons already stated. Because there is no evidence
    showing that GSK’s lawsuit against Abrika actually delayed
    Abrika’s entry into the market, the District Court rightly
    rejected it as a basis of liability.
    4.     The Impax and Watson Lawsuits and the
    Appellants’ Conspiracy Theory
    In contrast with the Anchen and Abrika lawsuits, GSK
    never joined the infringement litigation against Impax and
    Watson.      Biovail pursued those suits on its own.
    Nevertheless, the Appellants argue that all of Biovail’s
    Wellbutrin-related litigation was brought in furtherance of a
    conspiracy with GSK. Once again, their arguments are
    wanting.
    To avoid an adverse summary judgment on an antitrust
    conspiracy claim, a plaintiff must “present evidence ‘that
    37
    tends to exclude the possibility’ that the alleged conspirators
    acted independently.” Matsushita Elec. Indus. Co., Ltd. v.
    Zenith Radio Corp., 
    475 U.S. 574
    , 588 (1986) (quoting
    Monsanto Co. v. Spray-Rite Serv. Corp., 
    465 U.S. 752
    , 764
    (1984)). “[A] plaintiff must offer enough evidence that the
    inference of conspiracy is reasonable in light of the
    competing inferences of independent action ... .” Cosmetic
    Gallery, Inc. v. Schoeneman Corp., 
    495 F.3d 46
    , 51 (3d Cir.
    2007) (internal quotation marks and citation omitted). Mere
    communication between alleged co-conspirators, without
    more, is not sufficient to defeat the presumption of
    independent action. See In re Baby Food Antitrust Litig., 
    166 F.3d 112
    , 133 (3d Cir. 1999) (concluding that courts reject
    conspiracy claims that “seek to infer agreement from …
    communications despite a lack of independent evidence
    tending to show an agreement” (citation omitted) (alteration
    in original)); Alvord-Polk, Inc. v. F. Schumacher & Co., 
    37 F.3d 996
    , 1014 (3d Cir. 1994) (“Plaintiffs … seek to infer an
    agreement from those communications despite a lack of
    independent evidence tending to show an agreement and in
    the face of uncontradicted testimony that only informational
    exchanges took place. Without more, they cannot do so.”).
    The Appellants have markedly failed to offer
    meaningful evidence that excludes the possibility that Biovail
    acted independently. With respect to the suits against Impax
    and Watson, the evidence that the Appellants do point to is a
    “common interest agreement” between Biovail and GSK, 26 a
    26
    GSK and Biovail did not produce the common
    interest agreement. Instead, the parties stipulated that “[u]pon
    receiving [Anchen’s] Paragraph [IV] certification ... GSK and
    Biovail reached a common interest agreement with respect to
    38
    communication between Biovail and GSK in which GSK
    forwarded Impax’s paragraph IV certification, and an email
    from Biovail to GSK’s outside counsel stating that Biovail
    had not heard from GSK with respect to the Impax litigation
    and that Biovail “[did] not want to let the 45-day clock expire
    without consciously dealing with the issue.” 27 (JA 2347.)
    That evidence is insufficient. Biovail was the patentee and
    GSK the exclusive licensee on directly relevant technology,
    so communication between them acknowledging a common
    interest is hardly surprising and does not come close to
    supporting an inference that there was an unlawful conspiracy
    to stifle competition. Likewise, it is not surprising to see that
    the companies exchanged e-mails relating to their shared
    interest. The e-mails containing Impax’s paragraph IV
    certification and acknowledging Hatch-Waxman’s 45-day
    litigation window are the sort one would expect from two
    companies that share an interest in a pharmaceutical patent.
    That communication does not amount to a conspiracy to
    engage in sham litigation. See In re Nexium (Esomeprazole)
    Antitrust Litig., 
    842 F.3d 34
    , 56 (1st Cir. 2016) (explaining
    that pharmaceutical companies have valid reasons for
    their common legal interest in potential infringement of [the
    ’341 and ’327 patents] by Anchen or the filers of any
    additional ANDAs and related Paragraph [IV] notices ... .”
    (JA 11513.) GSK and Biovail further stipulated that the
    common interest agreement “related to the Paragraph [IV]
    certifications of [Anchen, Abrika, and Impax]” as well as the
    Anchen and Abrika actions. (Id.)
    27
    The Appellants do not have any evidence regarding
    communication between Biovail and GSK with respect to the
    Watson suit.
    39
    communicating with each other, and concluding that evidence
    of such communication, without more, is not enough to
    establish an unlawful conspiracy).
    The Appellants do not fare any better with respect to
    their claim that the Impax and Watson suits were brought as
    part of a larger conspiracy involving all four infringement
    actions, the Citizen Petition filed with the FDA, and the
    overall settlement agreement. Bare allegations cannot defeat
    summary judgment, and the Appellants have not pointed to
    any evidence to support their theory that there was a larger,
    overarching conspiracy.
    5.     The FDA Citizen Petition
    Biovail (but not GSK) filed a Citizen Petition with the
    FDA, expressing concern regarding the sufficiency of the
    FDA’s bioequivalence criteria for generic versions of
    Wellbutrin XL. 28 Biovail requested the FDA to require all
    generic manufacturers of the drug to do the following four
    things:
    28
    As already discussed, for a generic manufacturer to
    obtain FDA approval of an ANDA, the manufacturer must
    demonstrate that its drug is bioequivalent to a drug that went
    through the rigorous NDA approval process. Actavis, 133 S.
    Ct. at 2228. “Bioequivalence is the absence of a significant
    difference in the rate and extent to which the active ingredient
    or active moiety in pharmaceutical equivalents or
    pharmaceutical alternatives becomes available at the site of
    drug action when administered at the same molar dose under
    similar conditions in an appropriately designed study.” 21
    C.F.R. § 314.3 (2016).
    40
    (1) demonstrate that the generic formulation of
    [the drug] is bioequivalent to Wellbutrin ...
    Wellbutrin SR ... and Wellbutrin XL;
    (2) calculate and evaluate parameters in all of
    its bioequivalence trials based on concentrations
    of the patent drug and active metabolites; ...
    (3) conduct its bioequivalence trials at steady-
    state... [; and]
    [(4)] ... provide in vitro data demonstrating the absence
    of dose dumping if generic bupropion HCl extended-
    release tablets are consumed with alcohol.
    (JA 37509.) Six months after receiving the Petition, the FDA
    issued an interim response stating that the FDA “has been
    unable to reach a decision on [the] petition because it raises
    complex issues requiring extensive review and analysis by
    Agency officials.” (JA 37507.)
    Another six months passed and, on December 14,
    2006, the FDA issued its final response to the Petition,
    granting it in part, and denying it in part. The final response
    came on the same day that the FDA approved Anchen’s
    ANDA. The Appellants allege that Biovail’s Citizen Petition
    was anticompetitive and unlawful because, again, it was filed
    in furtherance of a conspiracy with GSK to delay generic
    entry. The District Court rejected that contention, concluding
    that the Appellants failed to “raise[] a genuine issue of
    material fact as to whether the unsuccessful and allegedly
    sham requests[(among the four requests Biovail made to the
    FDA)] caused any delay beyond the non-sham requests[.]”
    41
    (JA 127.) The Court also concluded that the Appellants failed
    to show that Biovail filed the Petition as part of a conspiracy
    with GSK.
    On appeal, the Appellants argue that each of the four
    requests in the Petition was a sham, that there is no
    requirement to show the extent to which the delay was caused
    by sham requests (as opposed to meritorious requests), and
    that there was evidence to show that the Petition was filed as
    part of a conspiracy between Biovail and GSK. Those
    arguments, though, are no more persuasive now than they
    were before the District Court.
    The most straightforward basis for affirmance is, once
    more, that the Appellants have failed to identify evidence
    showing that there was a conspiracy between Biovail and
    GSK, in this instance relating to the FDA petition. Just as
    with the sham litigation conspiracy claims, the Appellants
    must “present evidence ‘that tends to exclude the possibility’
    that the alleged conspirators acted independently[,]”
    
    Matsushita, 475 U.S. at 588
    (quoting Monsanto 
    Co., 465 U.S. at 764
    ), and must “offer enough evidence that the inference of
    conspiracy is reasonable in light of the competing inferences
    of independent action … .” Cosmetic 
    Gallery, 495 F.3d at 51
    (internal quotation marks omitted). They have not met that
    burden. There is no evidence in the record showing that
    Biovail and GSK collaborated, let alone illegally conspired,
    on Biovail’s Citizen Petition, and there is no evidence
    showing that Biovail filed the Petition at the direction of GSK
    or in furtherance of a plan involving GSK. On the contrary,
    the record indicates that GSK was not aware of Biovail’s
    42
    specific plans to file a petition, 29 that neither GSK nor Biovail
    wanted to collaborate on a petition, 30 that GSK refused to
    share its data with Biovail for use in a petition, 31 and that
    GSK disagreed with the general premise of Biovail’s
    Petition. 32
    29
    Eight days before Biovail filed its Petition, GSK
    employees sent an internal email expressing uncertainty as to
    whether Biovail had filed a petition.
    30
    GSK sent a fax to Biovail indicating that it “[did]
    not wish to participate in or be associated with ... Biovail
    explorations, deliberations, strategizing, decision-making, or
    ultimate advocacy with the FDA.” (JA 12356.) Biovail
    responded and confirmed that it “[did] not seek the
    participation of GSK[.]” (JA 12358.)
    31
    In e-mail correspondence, GSK employees
    acknowledged that “Biovail is curious if we have any
    information on metabolites that might form the basis of a
    challenge to the standard bioequivalence testing/standards.”
    (JA 13281.) In response, Stan Hull, a GSK employee,
    explained that “[the] information is available internally, but
    has not been shared with Biovail, and it is our
    recommendation not to share metabolite data with Biovail.”
    (JA 13282.)
    32
    Indeed, in a heading in their statement of undisputed
    facts, the Appellants state that “GSK concluded that the
    bioequivalence ... argument was wrong.”
    43
    In arguing otherwise, the Appellants point to an e-mail
    between two Biovail employees noting that “David [S]tout
    [who, at the time, was the President of U.S. Pharmaceutical
    Operations for GSK ... said that a generic to Wellbutrin XL
    would have to prove bioequivalence to [Wellbutrin IR] not to
    [Wellbutrin XL] to get approved.” (JA 12621.) Assuming
    the relevance of that statement, however, simple
    communication does not establish a conspiracy.             The
    Appellants claim that the e-mail shows that “GSK developed
    the [bioequivalence argument] and gave it to Biovail to put in
    the petition.” (JA 2383.) But the e-mail does not support that
    claim. Nothing in the e-mail indicates that GSK wanted
    Biovail to include the bioequivalence argument in a Citizen
    Petition – the e-mail does not mention a petition and, in fact,
    there was no petition to which GSK could refer – the e-mail
    was written over a year and a half before any FDA petition
    was filed.
    The Appellants also point to an e-mail from David
    Stout to several GSK employees that asked the employees to
    “coordinate with Biovail on ... [d]eveloping an agreement for
    [the concerns relating to bioequivalence, steady-state testing,
    and dose-dumping] and formulat[ing] a plan for the filing of
    the petition.” (JA 13261.) At the same time, though, the
    Appellants ignore a follow-up e-mail indicating that GSK did
    not want to move forward with the Petition. A week after
    Stout sent his e-mail, he received a response concluding that
    “a Citizen’s Petition requesting that all generic versions of
    Wellbutrin extended-release products be required to
    demonstrate a lack of food effect appears unnecessary as
    these are current confirmed requirements.” (JA 13279.) The
    evidence is thus inadequate to support the Appellants’ claim
    that GSK and Biovail collaborated on Biovail’s Petition,
    44
    much less that they conspired to use the Petition to suppress
    competition. 33 Because we can affirm the District Court on
    that basis, we do not need to consider whether GSK is entitled
    to Noerr-Pennington immunity with respect to the Petition. 34
    33
    As was the case with each of the four sham lawsuit
    claims, there is another causation problem. As we will
    explain in more detail below, Anchen’s launch would have
    been delayed by a blocking patent owned by Andrx. That
    means that any delay caused by Biovail’s FDA Petition is
    irrelevant – the blocking patent would have prevented a
    lawful launch even in the absence of Biovail’s Petition.
    34
    In evaluating Biovail’s Petition, the District Court
    considered the Petition as a series of four requests. The Court
    concluded that two of the four requests were successful, and
    thus not baseless, and that two of the four requests were
    potentially baseless. The Court then concluded that GSK was
    entitled to summary judgment because the Appellants had
    failed to show that their injury was attributable to the
    unsuccessful (and potentially sham) requests, rather than to
    the successful requests.
    We have doubts about that reasoning. The flaw is in
    viewing the Petition as four independent requests, rather than
    as a single petition. When considering whether a petition is
    entitled to immunity, courts should consider whether the
    petition as a whole is objectively baseless. See Tyco
    Healthcare Grp. LP v. Mut. Pharm. Co., 
    762 F.3d 1338
    , 1347
    (Fed. Cir. 2014); Cheminor Drugs, Ltd. v. Ethyl Corp., 
    168 F.3d 119
    , 123 (3d Cir. 1999) (“[W]e will determine whether
    Ethyl’s petition was objectively baseless ... .” (emphasis
    added)). While the District Court considered the merit of
    each of the Petition’s constituent requests, it did not reach any
    45
    6.     Serial Petitioning
    In addition to arguing that GSK engaged in sham
    litigation with respect to each of the four suits against generic
    manufacturers and the Citizen Petition, the Appellants
    contend that GSK engaged in serial petitioning, and thus in an
    abuse of the opportunity to litigate. They say that we should
    vacate and remand to allow the District Court to evaluate
    GSK’s actions in light of Hanover 3201 Realty, LLC v.
    Village Supermarkets, Inc., 
    806 F.3d 162
    (3d Cir. 2015), an
    opinion we issued after the District Court’s final judgment.
    GSK responds that the serial petitioning argument was
    waived and that, even if we consider it, Hanover is readily
    distinguishable. We decline to vacate and remand because
    the Appellants have not demonstrated that GSK engaged in
    serial petitioning. 35
    conclusions regarding whether the Petition, in toto, was
    objectively baseless. As a result, the Court’s consideration of
    causation and delay was premature.
    35
    GSK argues that the Appellants did not properly
    preserve the serial petitioning claim below, despite the fact
    that the Supreme Court precedent on which Hanover 3201
    Realty, LLC v. Village Supermarkets, Inc., 
    806 F.3d 162
    (3d
    Cir. 2015), relied was decided “more than 40 years ago,” and
    that the Appellants’ trial counsel was familiar with it from a
    prior case. (Ans. Br. 64.) The Appellants respond that
    asserting a general theory of sham litigation was sufficient
    because in doing so, they “recounted a series of meritless
    petitions filed to frustrate competition and prolong the
    defendants’ monopoly.” (Consolidated Reply Brief of Direct
    Purchaser and End-Payor Class Plaintiffs-Appellants 74.) In
    46
    In Hanover, we held that a plaintiff could more easily
    overcome Noerr-Pennington immunity when the defendant
    had engaged in multiple legal actions against the 
    plaintiff. 806 F.3d at 180
    . We explained that, “[w]here there is only
    one alleged sham petition, [PRE]’s exacting two-step test
    properly places a heavy thumb on the scale in favor of the
    defendant.” 
    Id. at 180.
    “In contrast, a more flexible standard
    is appropriate when dealing with a pattern of petitioning.” 
    Id. In the
    latter context, we ask “whether a series of petitions
    were filed with or without regard to merit and for the purpose
    of using the governmental process (as opposed to the outcome
    of that process) to harm a market rival and restrain trade.” 
    Id. To determine
    whether a practice of petitioning the
    government without regard to merit was used, “a court should
    perform a holistic review that may include looking at the
    defendant’s filing success—i.e., win-loss percentage—as
    circumstantial evidence of the defendant’s subjective
    motivations.” 
    Id. At the
    outset, we reject the contention that GSK
    engaged in serial petitioning through “four lawsuits and a
    petition[.]” (Op. Br. 116.) GSK was only involved in two of
    Hanover, we rejected an argument that the plaintiffs had
    waived a serial litigation claim where the plaintiffs
    “consistently” argued “that the sham exception applie[d]” and
    “alleg[ed] an ‘illegal scheme’ through a ‘series of sham
    litigations,’ [that] put Defendants on notice of the relevant
    
    facts[.]” 806 F.3d at 179
    n.13. Although the Appellants did
    not independently articulate the “series” claim in the District
    Court, we conclude that, as in Hanover, the recitation of
    sequential litigious activity was sufficient to preserve the
    claim.
    47
    the suits, and then only briefly. GSK did not file suit against
    Impax or Watson, nor did it join the Citizen Petition that was
    filed with the FDA. Biovail took those steps alone. And we
    have already rejected the Appellants’ arguments that GSK
    was engaged in a conspiracy with Biovail. When the
    Appellants’ serial petitioning claim is reduced to only the
    lawsuits against Anchen and Abrika, both of which GSK
    withdrew from, it must fail. The test for serial petitioning
    announced in Hanover explicitly applies to “a series of legal
    proceedings” or “a pattern of 
    petitioning[,]” 806 F.3d at 180
    ,
    and two proceedings – each against an independent defendant
    – does not constitute a pattern.
    The serial petitioning charge is particularly inapt
    because GSK’s actions were consistent with the design and
    intent of Hatch-Waxman. The Act incentivizes brand-name
    drug manufacturers to promptly file patent infringement suits
    by rewarding them with a stay of up to 30 months if they do
    so. 21 U.S.C. § 355(j)(5)(B)(iii). We are not inclined to
    penalize a brand-name manufacturer whose “litigiousness
    was a product of Hatch-Waxman.” Kaiser Found. Health
    Plan, Inc. v. Abbott Labs., Inc., 
    552 F.3d 1033
    , 1047 (9th Cir.
    2009). Doing so would punish behavior that Congress sought
    to encourage. See 
    id. (recognizing that
    the “volume of ...
    suits” filed by a brand-name manufacturer is “dependent on
    the number of generic companies attempting to enter the …
    marketplace, a matter over which the [brand-name
    manufacturer] ha[s] no control”). For that reason too, we
    agree with the District Court’s rejection of the Appellants’
    serial petitioning argument.
    48
    B.     Reverse Payment Settlement Agreement
    The second major point of contention on appeal relates
    to a set of agreements that resolved Biovail’s infringement
    suits against Anchen, Impax, and Watson, and Andrx’s
    infringement suits against GSK and Anchen. Each of the
    agreements was entered into on February 9, 2007, and
    together they settled many of the patent disputes related to
    Wellbutrin XL. The Appellants argue that the overall
    settlement was unlawful and anticompetitive. Before delving
    into the details of the agreements, we give some background
    on the events leading to the settlement.
    1.     Events Leading to the Settlement
    In January 2006, in anticipation of the FDA’s approval
    of Impax’s ANDA, Anchen, Impax, and Teva
    Pharmaceuticals U.S.A entered into an agreement under
    which Anchen would waive its first-filer exclusivity to allow
    Teva to market Impax’s 300 mg version of Wellbutrin XL. 36
    Pursuant to that agreement, Impax and Teva launched a
    generic version of 300 mg Wellbutrin XL in December 2006.
    36
    This is Teva’s first appearance in this case. It is
    another producer and distributor of generic drugs.
    As explained above, because Biovail filed its suit
    against Anchen promptly, it was able to delay the approval of
    Anchen’s ANDA for 30 months. However, Biovail did not
    file against Impax within 45 days of receiving Impax’s
    paragraph IV certification. As a result, the only barrier to the
    approval of Impax’s ANDA was Anchen’s first-filer
    exclusivity period.
    49
    That same month, Anchen’s ANDA was approved, and
    Anchen and Teva entered into a “Distribution and Supply
    Agreement,” under which Teva would launch Anchen’s
    150 mg version of Wellbutrin XL. At that point, GSK,
    Biovail, and Teva (as the distributor for Anchen and Impax)
    entered into a “‘standstill’ agreement under which Teva,
    Anchen, and Impax agreed not to launch any more 300 mg
    generic product or any 150 mg generic product, and Biovail
    ... agreed not to launch any authorized generic version of
    either dosage strength.” 37 (JA 2435.)
    In the midst of that standstill, in February 2007, the
    parties entered into the series of agreements constituting the
    settlement. By that time, Biovail had lost its infringement
    suit against Anchen in district court and had an appeal
    pending in the United States Court of Appeals for the Federal
    Circuit. 38 Each of the other infringement cases was pending
    in district court. Also pending was a federal case filed by
    Biovail against the FDA challenging the FDA’s treatment of
    Biovail’s Citizen Petition.
    37
    An “authorized generic” is a non-branded version of
    a brand-name drug that is produced by the brand-name
    company itself.
    38
    The appeals process was at an early stage – Biovail
    filed its notice of appeal on September 13, 2006, and its
    opening brief on December 14, 2006.
    50
    2.     The Settlement
    Five agreements constituting the overall settlement are
    relevant here. The first was between GSK and Andrx and
    provided that GSK would settle with Andrx, “paying $35
    million to cover past use of the technology described in
    Andrx’s patent, plus an ongoing royalty rate in exchange for a
    license to the patent.” 39 (Ans Br. 14; see also JA 34043.)
    GSK also obtained the right to sublicense the Andrx patent.
    The second agreement was a license between Teva and
    Biovail. It contained three relevant provisions. First, it
    granted Teva a 180-day exclusive license to certain Biovail
    patents, 40 so that Teva could sell a 150 mg version of generic
    Wellbutrin XL beginning on May 30, 2008, or earlier if
    Biovail lost its appeal in the Anchen case. 41 Second, the
    agreement granted Teva an exclusive license to Biovail
    patents so that it could sell a 300 mg version of generic
    39
    In November 2006, Andrx was acquired by Watson.
    For simplicity, we will continue to refer to Andrx by that
    name.
    40
    To ensure that the license would, in fact, be
    exclusive, Biovail amended its development agreement with
    GSK. To facilitate the settlement, GSK agreed to refrain
    from launching an authorized generic version of 150 mg
    Wellbutrin XL for the duration of Teva’s exclusive license.
    41
    The agreement contained five other “trigger”
    provisions that would allow Teva to market generic versions
    of Wellbutrin. None of the other provisions is relevant here.
    51
    Wellbutrin XL. 42 The license ran from December 13, 2006
    through June 12, 2007. 43 Finally, the agreement required
    Biovail to provide Teva with a supply of 150 mg and 300 mg
    generic Wellbutrin XL. 44 Specifically, Biovail agreed to
    supply Teva with 75 million tablets of the 150 mg dosage.
    The agreement also contained two unlimited supply
    provisions (one for the 150 mg dosage and one for the 300
    mg dosage), obligating Biovail to provide Teva with an
    unlimited supply of Wellbutrin XL in the event that Biovail’s
    Citizen Petition ended up interfering with Teva’s launch.
    The third agreement was between Anchen and Biovail.
    In that agreement, Biovail granted Anchen a sublicense to
    Andrx’s ’708 patent – the patent that had been the subject of
    litigation involving Anchen’s 150 mg generic version of
    Wellbutrin XL. 45 The parties also acknowledged that the
    42
    Biovail and GSK similarly amended their
    development agreement to preclude GSK from launching an
    authorized generic version of 300 mg Wellbutrin XL.
    43
    The license was written to retroactively authorize the
    sales that Teva had made prior to entering the license
    agreement. The Appellants contend that the license was
    meaningless and that “Teva did not need a license to make
    and sell the product because Teva was already doing so.” (JA
    2635.)
    44
    The agreement specified that the tablets must be
    “Generic NDA Equivalent.” (JA 34081.)
    45
    The agreement explains that Biovail was an assignee
    of the license agreement between Andrx and GSK, and thus
    52
    agreement did not “settle or otherwise end the Biovail
    Anchen lawsuit.” (JA 3697.)
    The fourth agreement was between Biovail and Impax,
    in which Biovail agreed to dismiss its infringement suit
    against Impax and agreed not to sue Impax for selling or
    manufacturing generic versions of Wellbutrin XL outside of
    Anchen’s 180-day exclusivity period.
    The fifth agreement was an “omnibus” one in which
    the several parties acknowledged that the second through fifth
    agreements were related to each other and agreed to submit
    those agreements to the FTC for approval. The parties further
    agreed to modify the agreements in response to any FTC
    concerns. 46
    that Biovail had the ability to grant a sublicense to Andrx’s
    patent.
    46
    By statute, the parties were required to submit their
    several settlement agreements to the FTC within 10 days.
    Medicare      Prescription     Drug,    Improvement,      and
    Modernization Act of 2003, Pub. L. No. 108-173, § 1112(a),
    117 Stat 2066, 2461-62 (2003). The omnibus agreement
    required the parties to submit the agreements to the FTC
    within two days and to either revise or terminate the
    agreement in response to any FTC concerns. In addition to
    the five agreements described above, Andrx sent a letter to
    Anchen explaining that, in light of the license agreement
    between GSK and Andrx, Andrx would dismiss its
    infringement suit against Anchen. That same day, Biovail
    and GSK amended their development agreement (the
    agreement that granted GSK an exclusive license to Biovail’s
    53
    Pursuant to the terms of the agreements, Anchen
    waited until May 2008 to launch its 150 mg generic version
    of Wellbutrin XL, and GSK waited 180 days to launch
    authorized generic versions of both 150 mg and 300 mg
    Wellbutrin XL.
    3.     The Appellants Cannot Prevail on Their
    Antitrust Claims Pertaining to the
    Alleged Reverse Payment
    In order to prevail on an antitrust claim, a private
    plaintiff must establish antitrust standing, Ethypharm S.A.
    France v. Abbott Laboratories, 
    707 F.3d 223
    , 232-33 (3d Cir.
    2013), and must show that the defendant’s actions violated
    antitrust law. Phillip E. Areeda & Herbert Hovenkamp,
    Fundamentals of Antitrust Law 3-16 (4th ed. 2015). In this
    case, there is an additional threshold question – whether the
    challenged agreements are immune from antitrust scrutiny as
    the valid exercise of patent rights. See Dawson Chem. Co. v.
    Rohm & Haas Co., 
    448 U.S. 176
    , 215 (1980) (explaining that
    “the essence of a patent grant is the right to exclude others
    from profiting by the patented invention”); 
    Actavis, 133 S. Ct. at 2238
    (Roberts, C.J., dissenting) (“A patent grants the right
    to exclude others from profiting by the patented invention. In
    doing so it provides an exception to antitrust law, and the
    scope of the patent ... forms the zone within which the patent
    patents) to bring it into compliance with the substance of the
    Teva-Biovail agreement. Finally, Biovail agreed to dismiss
    its suit against Watson. There was no payment (reverse or
    otherwise) associated with the Biovail-Watson settlement.

    holder may operate without facing antitrust liability.”
    (internal quotation marks and citation omitted)).
    a)     The Agreements Are Not Immune
    from Antitrust Scrutiny; the Rule
    of Reason Test Applies
    The Supreme Court considered the legality of reverse
    payment settlements in FTC v. Actavis, 
    133 S. Ct. 2223
    . In
    that case, a brand-name drug manufacturer sued an ANDA
    applicant. 
    Id. at 2229.
    After litigating the case for several
    years, the parties entered into a settlement agreement whereby
    the brand manufacturer paid the generic manufacturer tens of
    millions of dollars in exchange for the generic’s agreement to
    delay its entry into the market for nine years. 
    Id. at 2229-30.
    The FTC filed suit challenging the settlement agreement. 
    Id. at 2227.
    Although the United States Court of Appeals for the
    Eleventh Circuit held that reverse payment settlements should
    be immune from antitrust liability, as long as they fall within
    the scope of the relevant patents, FTC v. Watson Pharm., Inc.,
    
    677 F.3d 1298
    , 1312 (11th Cir. 2012), the Supreme Court saw
    it differently. It said that “reverse payment settlements ... can
    sometimes violate the antitrust laws” and that “courts
    reviewing such agreements should ... apply[] [the] ‘rule of
    reason’ [test].” 
    Actavis, 133 S. Ct. at 2227
    , 2237. 47 In
    reaching that conclusion, the Court observed that “it would be
    incongruous to determine antitrust legality by measuring the
    47
    The Supreme Court explicitly rejected the claim that
    reverse payment settlement agreements are “presumptively
    unlawful” and concluded that it would also be improper to
    evaluate reverse payment agreements via a “quick-look”
    approach. 
    Id. at 2237.
    55
    settlement’s anticompetitive effects solely against patent law
    policy, rather than by measuring them against procompetitive
    antitrust policies as well.” 
    Id. at 2231.
    The Court then
    explained that reverse payments can generate “genuine
    adverse effects on competition” by allowing brand
    manufacturers to “avoid the risk of patent invalidation or a
    finding of noninfringement.” 
    Id. at 2235-36.
    Ultimately, the
    Court concluded that “a reverse payment, where large and
    unjustified, can bring with it the risk of significant
    anticompetitive effects[.]” 
    Id. at 2237.
    In King Drug Co. of Florence, Inc. v. Smithkline
    Beecham Corp., 
    791 F.3d 388
    (3d Cir. 2015), we considered
    whether antitrust scrutiny under Actavis was limited to
    reverse payments of cash, or whether other “transfers of
    value” would also be subject to scrutiny. Like the agreement
    at issue in this case, King involved a settlement in which a
    brand manufacturer agreed not to produce an “authorized
    generic” version of its drug – a so-called “no-AG agreement.”
    
    Id. at 394.
    The antitrust plaintiffs in that case alleged that the
    no-AG agreement qualified as a reverse payment under
    Actavis. See 
    id. We agreed
    and held that “Actavis’s holding
    [could not] be limited to reverse payments of cash.” 
    Id. at 403.
    We explained:
    [A] brand’s commitment not to produce an
    authorized generic means that it must give up
    the valuable right to capture profits ... . The no-
    AG agreement transfers the profits the patentee
    would have made from its authorized generic to
    the settling generic—plus potentially more ...
    because there will now be a generic monopoly
    instead of a generic duopoly.
    56
    
    Id. at 405.
    As a result, we concluded that “no-AG agreements
    are likely to present the same types of problems as reverse
    payments of cash” and that “[t]he anticompetitive
    consequences of [a no-AG agreement] may be as harmful as
    those resulting from reverse payments of cash.” 
    Id. at 404-
    05.
    When evaluating the challenged settlements in this
    case, the District Court suggested, but did not hold, that they
    might be beyond the reach of antitrust law. According to the
    Court, “the Wellbutrin Settlement does not present the same
    antitrust concerns that motivated the court in Actavis to
    subject the settlement to antitrust scrutiny” because “the
    Wellbutrin Settlement required the underlying patent
    litigation to continue, maintaining the risk of a finding of
    patent invalidity or non-infringement[.]”        (JA 182-83.)
    Despite that intimation, the Court declined to hold that “any
    reverse payment that allows the underlying patent litigation to
    continue is automatically exempt from the antitrust laws.”
    (JA 184.) Instead, the Court analyzed the settlement using
    the rule of reason. On appeal, GSK echoes the initial
    intimation of the District Court and maintains that “[t]he
    settlement did not pose the anticompetitive harm the Supreme
    Court identified in Actavis[.]” (Ans. Br. 67.) We disagree.
    In light of Actavis and our decision in King, the
    agreements at issue in this case, as they relate to Anchen’s
    generic version of 150 mg Wellbutrin XL, must be evaluated
    under the rule of reason test. As explained above, the
    agreements include an alleged reverse payment and pay-for-
    delay scheme: in exchange for a 180-day no-AG agreement
    from Biovail and GSK (the reverse payment), Anchen agreed
    not to launch a generic version of 150 mg Wellbutrin XL until
    57
    the occurrence of a triggering event. Moreover, there is some
    support in the record for the assertion that the reverse
    payment is large and unjustified, see 
    Actavis, 133 S. Ct. at 2237
    (suggesting that reverse payments are especially
    problematic if they are “large and unjustified”). First, the
    payment can be said to be large. According to the
    Appellants’ economic expert, 48 the no-AG agreement was
    worth $233 million to Anchen, Teva, and Impax – an amount
    that would qualify as large in most any context. See 
    Actavis, 133 S. Ct. at 2237
    (explaining that “the likelihood of a reverse
    payment bringing about anticompetitive effects depends upon
    its size [and] scale in relation to the payor’s anticipated future
    litigation costs”). The “payment,” i.e., the no-AG agreement,
    could also be said to be unjustified in the sense of being
    unexplained. 49 In particular, it was not tied to the merits of
    the litigation between Biovail and Anchen. We know that the
    48
    The District Court granted a Daubert motion to
    exclude that expert’s opinion relating to the rule of reason
    analysis. However, the Daubert motion did not appear to
    challenge the expert’s opinions with respect to the value
    associated with the no-AG agreement. And, in Actavis, the
    Supreme Court recognized the immense value associated with
    market exclusivity. See 
    Actavis, 133 S. Ct. at 2229
    (citing C.
    Scott Hemphill, Paying for Delay: Pharmaceutical Patent
    Settlement as a Regulatory Design Problem, 81 N.Y.U. L.
    Rev. 1553, 1579 (2006)).
    49
    We intend no comment on whether a no-AG
    promise could be justified in the sense of being a sound
    exercise of business judgment and consonant with good
    public policy.
    58
    no-AG agreement was not linked to the merits of the
    litigation because its value did not depend on the outcome of
    the appeal before the Federal Circuit. The duration of the no-
    AG promise was fixed at 180 days, regardless of who
    prevailed in the case, and that duration provided value to
    Anchen, as well as to Teva and Impax. 50 Because the
    50
    It is worth noting that this case differs from Actavis
    and King in at least one important respect: in both Actavis and
    King, the challenged agreements ended litigation between the
    brand-name manufacturer and the generic manufacturer. In
    this case, however, the agreements allowed Biovail’s appeal
    to continue. (See JA 3697 (explicitly noting that the
    agreement did not “settle or otherwise end the Biovail
    Anchen lawsuit”).) In acknowledging that difference, the
    District Court concluded that the agreements in this case
    “do[] not present the same antitrust concerns that motivated
    the court in Actavis to subject the settlement to antitrust
    scrutiny.” (JA 183.) We question that conclusion. While
    there is language in Actavis that describes the premature
    termination of litigation as an anticompetitive harm, 
    see 133 S. Ct. at 2236
    (explaining that a patentee should not be
    allowed to “us[e] its monopoly profits to avoid the risk of
    patent invalidation or a finding of noninfringement”), the
    Supreme Court’s holding was not so narrow. Instead, Actavis
    stands for the broader proposition that both “patent and
    antitrust policies are ... relevant in determining the ‘scope of
    the patent monopoly’—and consequently antitrust law
    immunity—that is conferred by a patent.” 
    Id. at 2231.
    In
    other words, the Court took issue with reverse payments not
    simply because they could lead to the premature termination
    of litigation, but rather because they eliminate the risk of
    competition. 
    Id. at 2236;
    King, 791 F.3d at 405
    .
    59
    agreements at issue here are such as to implicate the concerns
    identified in Actavis, they are not immune from antitrust
    scrutiny and must, to a degree, be evaluated under the rule of
    reason test.
    That “to a degree” qualifier is added because our
    conclusion is limited to the agreements as they relate to
    Anchen’s generic version of 150 mg Wellbutrin XL. We
    reach a different conclusion with respect to the agreements as
    they relate to Anchen’s 300 mg Wellbutrin XL. 51 As
    While the agreements at issue here did not end the
    litigation between Biovail and Anchen, they nevertheless
    implicate the kinds of concerns articulated in Actavis by
    delaying the entry of 150 mg generic Wellbutrin XL and by
    delaying the entry of an authorized generic version of both
    150 and 300 mg Wellbutrin XL. That conclusion follows
    directly from Actavis and King and is also supported by the
    FTC, which filed an amicus brief in this case. (See FTC Br.
    15 (“An agreement that forecloses the possibility of at-risk
    entry into the market (in exchange for shared monopoly
    profits) can also be anticompetitive under that analysis.”).)
    The view of the law espoused by the FTC, adopted by the
    majority in Actavis, and followed by our Court in King, has
    been subject to cogent criticism, see, e.g., 
    Actavis, 133 S. Ct. at 2240-47
    (Roberts, C.J., dissenting), but the controlling
    precedent is what it is.
    51
    It does not appear that the Appellants have presented
    any arguments relating exclusively to Anchen’s generic
    version of 300 mg Wellbutrin XL. As a result, any arguments
    the Appellants might have regarding the 300 mg product
    could be viewed as waived. Nagle v. Alspach, 
    8 F.3d 141
    ,
    60
    explained above, Anchen, in partnership with Impax and
    Teva, launched a 300 mg version of Wellbutrin XL in
    December 2006 – as soon as its ANDA was approved. The
    agreements reached in February 2007 allowed Teva to
    continue marketing that product. As a result, there was no
    delay associated with the 300 mg product and the analysis in
    Actavis does not apply. As a result, any pay-for-delay claim
    unique to Anchen’s 300 mg product must fail. 52
    b)     The Appellants Do Not Have
    Antitrust Standing
    In order to maintain an antitrust suit, a plaintiff must
    establish antitrust standing, which is distinct from Article III
    standing. While Article III standing is rooted in the
    Constitution, antitrust standing is a judge-made doctrine. 53
    143 (3d Cir. 1993). However, for the reasons stated above,
    the Appellants would not prevail on that issue even if it were
    not waived.
    52
    One could argue that the no-AG agreement relating
    to the 300 mg product was part of the payment used to
    persuade Anchen to delay its launch of the 150 mg product.
    If one adopts that view, then the 300 mg no-AG agreement
    would be subject to the same analysis as the 150 mg no-AG
    agreement and there would not be any claim unique to the
    generic 300 mg product.
    53
    Though judge-made, federal antitrust standing is
    rooted in federal statutory law, and antitrust standing under
    state law is likewise rooted in the respective statutes of the
    several states represented within the ranks of the indirect-
    61
    Associated Gen. Contractors of Cal., Inc. v. Cal. State
    Council of Carpenters, 
    459 U.S. 519
    , 534-35 & n.31 (1983);
    Ethypharm S.A. France v. Abbott Labs., 
    707 F.3d 223
    , 232
    n.17 (2013) (“[A]ntitrust standing is based on prudential
    principles.”). It is not a jurisdictional requirement. In re
    Modafinil Antitrust Litig., 
    837 F.3d 238
    , 263 n.30 (3d Cir.
    2016). And while “[h]arm to the antitrust plaintiff is
    sufficient to satisfy the constitutional standing requirement of
    injury in fact,” courts must also consider “whether the
    plaintiff is a proper party to bring [the] private antitrust
    action.” Associated Gen. 
    Contractors, 459 U.S. at 535
    n.31.
    In that sense, antitrust standing is more properly viewed as an
    element of an antitrust claim that can be resolved at summary
    judgment. Ethypharm S.A. 
    France, 707 F.3d at 232

    purchaser Appellants. The state requirements for antitrust
    standing are functionally identical to the federal requirements
    in this respect – each of the state antitrust laws asserted in this
    case requires antitrust plaintiffs to prove that they have
    suffered an antitrust injury. Moreover, the standards for
    proving antitrust injury under the state laws appear to be
    identical to the standards under federal law. See Breakdown
    Servs., Ltd. v. Now Casting, Inc., 
    550 F. Supp. 2d 1123

    Res.,

    a result, our standing and causation analysis on this issue
    applies equally to the direct purchasers’ claims and the
    indirect purchasers’ claims.

    antitrust standing at summary judgment, and determining

    Brick Co.,] [t]he Court held that § 4 [of the Clayton Act] did
    not permit ... indirect purchasers ... to recover for the

    However, indirect purchasers do have standing to assert
    antitrust claims in each of the state causes of action asserted
    here. Nev. Rev. Stat. § 598A.210 (Nevada statute granting

    In order to establish antitrust injury here, the
    Appellants must show that the harm they say they
    experienced – increased drug prices for Wellbutrin XL (and
    its generic equivalents) – was caused by the settlement they
    are complaining about. See Zenith Radio Corp. v. Hazeltine
    Res., Inc., 
    395 U.S. 100
    , 114 n.9 (1969) (explaining that,
    under the Clayton Act, a plaintiff must prove that it has
    suffered at least “some damage flowing from the unlawful
    conspiracy”). The Appellants attempt to meet their burden by
    pointing to evidence showing that, in the absence of the
    agreements, Anchen (partnering with Teva) would have
    launched its 150 mg generic no later than the middle of 2007.
    At first glance, that argument seems appealing.
    Indeed, the District Court found that there was at least a
    question of fact as to whether Anchen would have launched
    the drug in June 2007. The problem with the argument,
    however, is that it does not take into account Andrx’s
    blocking patent, the ’708 patent. It is not enough for the
    Appellants to show that Anchen wanted to launch its drug;
    they must also show that the launch would have been legal.
    After all, if the launch were stopped because it was illegal,
    then the Appellants’ injury (if it could still be called that)

    would be caused not by the settlement but by the patent laws
    prohibiting the launch. See In re Nexium (Esomeprazole)
    Antitrust Litig., 
    842 F.3d 34
    , 62-63 (1st Cir. 2016) (“[T]he
    argument that [the generic manufacturer] would have incurred
    the risk of launching at risk or that [it] would have won its ...
    suit against [the patent holder] depends on the theory that ...
    [the] patents were invalid or not infringed by a generic
    version.”); Phillip E. Areeda & Herbert Hovenkamp,
    Fundamentals of Antitrust Law § 3.04[B] (rev. 4th ed. Supp.
    2015) (“[A] plaintiff cannot be injured in fact by private
    conduct excluding it from the market when a statute prevents
    the plaintiff from entering that market in any event.”). 56
    That a regulatory or legislative bar can break the chain
    of causation in an antitrust case is beyond fair dispute. For
    example, in RSA Media, Inc. v. AK Media Grp., Inc., 
    260 F.3d 10
    , 15 (1st Cir. 2001), the First Circuit decided that the
    plaintiff was excluded from the outdoor billboard market not
    because of the defendant’s actions but rather “because the
    Massachusetts regulatory scheme ... [prevented] new
    billboards from being built.” Similarly, in In re Canadian
    Import Antitrust Litigation, 
    470 F.3d 785
    , 790-91 (8th Cir.
    2006), the Eighth Circuit held that the plaintiffs faced higher
    drug prices not because drug companies excluded cheaper
    56
    GSK also argues that Anchen’s launch would have
    been blocked by FDA regulations relating to Anchen’s
    production facilities. We do not consider that argument
    because, even if it were given full weight, it would only show
    that Anchen would have had to wait until June 12, 2007 to
    launch – a date that was almost a year prior to its actual
    launch. In other words, the argument relates to the length of
    delay, rather than the existence of a delay.
    66
    Canadian drugs from the market but because federal law
    excluded the cheaper Canadian drugs. See City of Pittsburgh
    v. W. Penn Power Co., 
    147 F.3d 256
    , 265 (3d Cir. 1998)
    (applying the same principle and concluding that any injury
    suffered by the plaintiff resulted from “the realities of the
    regulated environment” rather than from the defendants’
    actions). In this case, the launch of Anchen’s 150 mg version
    of Wellbutrin XL was effectively blocked by federal patent
    law, which, through Andrx’s ’708 patent, would have
    prevented market entry.
    The Appellants offer two arguments to fend off that
    conclusion – one legal and one factual. Their legal argument
    is that the reasoning just given was repudiated by our decision
    in Consolidated Express, Inc., v. New York Shipping
    Association. 
    602 F.2d 494
    (3d Cir. 1979), vacated 
    448 U.S. 902
    (1980), remanded and affirmed, 
    641 F.2d 90
    (3d Cir.
    1981). They misread that case. In Consolidated Express, we
    held that an antitrust plaintiff’s improper conduct did not
    preclude that plaintiff from asserting an antitrust claim
    unrelated to the improper conduct. 
    Id. at 508.
    By contrast,
    our holding in this case is that the antitrust claim fails because
    the actions of GSK, the defendant, did not actually cause the
    Appellants’ claimed injury. But even if the Appellants had a
    correct reading of Consolidated Express, their argument
    would still fail because that case predates significant
    developments       in    antitrust    standing      jurisprudence.
    Consolidated Express was decided in 1979, before the
    Supreme Court established its antitrust standing “factors” in
    Associated General Contractors four years later.               See
    Merican, Inc. v. Caterpillar Tractor Co., 
    713 F.2d 958
    , 965
    (3d Cir. 1983) (applying the Supreme Court’s decision in
    Associated General Contractors). We later adopted the very
    67
    argument that the Appellants now claim is not good law. In
    City of Pittsburgh we said that no antitrust standing exists
    when a plaintiff’s grievance is caused by a regulatory scheme
    rather than by the defendant’s 
    actions. 147 F.3d at 266
    . We
    decline to deviate from the well-reasoned path marked in City
    of Pittsburgh.
    The Appellants’ factual response is that, but for the
    challenged agreements, Anchen would have been able to
    launch its 150 mg version of Wellbutrin XL without running
    afoul of Andrx’s patent. They offer two scenarios. First, they
    argue that, in the absence of the challenged agreements,
    Anchen would have obtained a license to Andrx’s patent. We
    will refer to that as the license-based scenario. Alternatively,
    they argue that, in the absence of the challenged agreements,
    Anchen would have prevailed against Andrx in litigation. We
    will refer to that as the litigation-based scenario. The record
    supports neither.
    (1)    License-Based Scenario
    The Appellants contend that, for at least three reasons,
    Anchen would have obtained a license from Andrx. First,
    they say that GSK failed to produce evidence “showing [that]
    … GSK’s no-AG payment or the generic delay … were
    necessary in order [for Anchen] to secure a ... license [to
    Andrx’s patent].” (Op. Br. 74.) That argument, however,
    flips the burden of proof. As the plaintiffs, the Appellants
    have the burden of proving that they have been injured. In
    order to withstand summary judgment, they must point to
    evidence affirmatively showing that Anchen could have
    launched. See W. Penn Allegheny Health Sys., Inc. v. UPMC,
    
    627 F.3d 85
    , 101 (3d Cir. 2010) (“[T]he plaintiff must
    68
    establish that it suffered an antitrust injury.”). It is no good
    saying that the defendants have failed to disprove causation.
    See 
    id. Second, the
    Appellants say that Andrx had “an
    independent economic interest” in providing a license to
    Anchen. (Op. Br. 74.) Their reasoning is that Andrx was a
    non-practicing entity and thus “could only profit from its ‘708
    patent through licenses.” (Id. at 74.) That argument is both
    incorrect and insufficient. The argument is incorrect because,
    as noted 
    above, supra
    n.39, Watson acquired Andrx in
    November 2006. That means that Andrx was, by that time,
    not a non-practicing entity and in fact had a reason to deny
    Anchen a license. If Anchen were precluded from launching
    its product, then Anchen would waive its exclusivity period,
    allowing Watson (a/k/a Andrx) to enter the market earlier.
    See 21 U.S.C. § 355(j)(5)(D)(i) (outlining the conditions in
    which a first-filer waives its exclusivity). But, even if the
    Appellants’ argument were better rooted in reality, it would
    be insufficient. In order to withstand summary judgment, the
    Appellants must produce evidence from which a reasonable
    jury could conclude that it is more likely than not that Anchen
    would have obtained a license. Evidence showing that
    Anchen may have been able to obtain a license does not meet
    that standard. A plaintiff cannot satisfy the summary
    judgment burden based on speculation alone. See Halsey v.
    Pfeiffer, 
    750 F.3d 273
    , 287 (3d Cir. 2014) (“[A]n inference
    based upon a speculation or conjecture does not create a
    material factual dispute sufficient to defeat [entry of]
    summary judgment.” (quoting Robertson v. Allied Signal,
    Inc., 
    914 F.2d 360
    , 382 n.12 (3d Cir. 1990))); Fedorczyk v.
    Caribbean Cruise Lines, Ltd., 
    82 F.3d 69
    , 76 (3d Cir. 1996)
    (affirming a grant of summary judgment because “[b]ased on
    69
    the evidence presented, a jury could only speculate” as to
    whether the defendant’s actions actually caused the claimed
    injury). 57
    Third, the Appellants argue that Anchen was
    negotiating a license agreement with Andrx in the days
    preceding the agreements and had agreed on all but one term.
    Based on those negotiations, the Appellants argue, a
    57
    The Appellants point to our recent decision in In re
    Fosamax (Alendronate Sodium) Products Liability Litigation,
    
    852 F.3d 268
    (3d Cir. 2017), to support their claim that juries
    are “‘routinely’ given questions that permissibly require them
    to ‘predict the outcome of a hypothetical scenario’ or to
    ‘speculate’ or ‘guess what could have happened in a
    counterfactual setting’ by assessing corporate motives and
    thought processes or by ‘evaluat[ing] inference[s] about
    human behavior.’” (March 27, 2017 28(j) letter at 2
    (alterations in original) (quoting 
    Fosamax, 852 F.3d at 289
    ,
    297, 299).) Their argument is correct, but irrelevant. The
    fact that juries may predict the outcome of hypothetical
    scenarios says nothing about the type or amount of evidence
    that is needed for a plaintiff to withstand summary judgment
    on a claim involving a counterfactual scenario. As explained
    above, the Appellants have not presented sufficient evidence
    upon which a reasonable jury could rely to conclude that it is
    more likely than not that Anchen and Andrx would have
    entered into a license agreement in the counterfactual world.
    While it may be better than speculative that Anchen and
    Andrx would have had an incentive to talk, it is, on this
    record, pure speculation that they would have reached an
    agreement.
    70
    reasonable jury could infer that the two companies would
    have reached an agreement. But this argument too is
    completely speculative. It is certainly possible that Anchen
    and Andrx would have reached an agreement, but it is also
    certainly possible that the negotiations would have stalled and
    failed. Many a contract has foundered on a single deal-
    breaker point. Without more specific or concrete evidence,
    the jury in this case would be left with nothing on which it
    could rely to reach a conclusion one way or the other.
    Summary judgment was thus appropriate.
    (2)    Litigation-Based Scenario
    The Appellants’ litigation-based scenario is premised
    on the idea that Anchen would have prevailed in Andrx’s
    infringement suit. If Andrx’s ’708 patent were invalid, or if
    it did not cover Anchen’s product, then patent law would not
    have prevented Anchen’s launch. In order to evaluate the
    merit of the litigation-based scenario, we must consider the
    substance of that underlying litigation. 58
    58
    In the Actavis decision, there was a debate between
    the majority and the Chief Justice on whether lower courts
    would be required to resolve substantive patent questions in
    order to adequately assess the merits of reverse payment
    antitrust claims. Writing for the majority, Justice Breyer
    asserted that “it is normally not necessary to litigate patent
    validity to answer the antitrust question ... .” Actavis, 133 S.
    Ct. at 2236. The Chief Justice disagreed:
    [S]ettling a patent claim cannot possibly impose
    unlawful anticompetitive harm if the patent
    holder is acting within the scope of a valid
    71
    The Appellants make two arguments relative to the
    merits of the patent litigation. First, they say that we should
    view the size of the reverse payment as “a surrogate for [the]
    patent’s weakness” and conclude that GSK “knew [that
    Andrx’s patent] could not prevent generic competition.” (Op.
    Br. 86.) While the size of a reverse payment may have some
    relevance in determining how confident a litigant is in the
    strength of its case, 
    Actavis, 133 S. Ct. at 2236-37
    (“In a
    word, the size of the unexplained reverse payment can
    provide a workable surrogate for a patent’s weakness ... .”), it
    is far from dispositive. That is especially so when, as in this
    case, the settlement is complex and multi-faceted. For
    patent and therefore permitted to do precisely
    what the antitrust suit claims is unlawful. This
    means that in any such antitrust suit, the
    defendant (patent holder) will want to use the
    validity of his patent as a defense—in other
    words, he’ll want to say “I can do this because I
    have a valid patent that lets me do this.” I
    therefore don’t see how the majority can
    conclude that it won’t normally be “necessary
    to litigate patent validity to answer the antitrust
    question[.]”
    
    Id. at 2244
    (Roberts, C.J., dissenting). The present case
    appears to vindicate the Chief Justice’s analysis. As he
    predicted, GSK argues that the Andrx patent (which was a
    central component of the agreements) defeats the Appellants’
    suit, and, as he predicted, we cannot resolve this aspect of the
    case without considering the merits of the underlying patent
    dispute.
    72
    example, GSK and Biovail may have offered the reverse
    payment not because they thought Andrx had a weak patent
    but rather because they thought Anchen would improperly
    evaluate the patent and launch at-risk. 59 In that scenario,
    GSK would lose substantial revenue from having a generic
    competitor and would not be entitled to damages if the patent
    were vindicated because the patent belonged to Andrx, not to
    GSK. That there are multiple plausible ways to interpret the
    reverse payment in this case means that the payment alone
    tells us less about the merits of the underlying case than the
    Appellants wish.
    We are also persuaded by an argument raised in the
    amicus brief filed by a group of antitrust economists (“the
    Economists”). That group explains why risk aversion makes
    it difficult to use the size of a settlement as a proxy for the
    brand-name’s likelihood of success in litigation:
    To explore why risk aversion could lead to the
    exchange of consideration having nothing to do
    with delayed entry, consider a lottery ticket with
    a 50% chance of a $0 payoff and a 50% chance
    of a $100 million payoff—i.e., the lottery ticket
    has an expected payoff of $50 million. Most
    people holding such a ticket would be willing to
    accept less than the expected payoff amount to
    59
    In the context of patent litigation, a launch is said to
    be “at-risk” if it takes place before the questions of
    infringement and validity are resolved, either through
    litigation or a license. See In re Modafinil Antitrust 
    Litig., 837 F.3d at 244
    .
    73
    achieve certainty. If a person would trade the
    aforementioned lottery ticket for a certain
    outcome of $20 million, he or she would
    essentially be willing to pay $30 million dollars
    to eliminate the risk of holding the lottery ticket
    that might result in the $0 payoff. Accepting
    the certain outcome of $20 million dollars,
    however, does not reflect a belief that a $0
    payoff is anything more than [a] 50% [risk].
    (Antitrust Economists Br. 11 (internal citation omitted).) We
    think that reasoning serves as an effective rebuttal to the
    Appellants’ claim that the size of the reverse payment is a
    “surrogate” for the weakness of the ’708 patent.
    The Appellants’ second argument relating to the
    litigation-based scenario relies on testimony provided by
    Martin Adelman, GSK’s expert. Adelman estimated that
    Andrx had an 80% chance of prevailing with respect to
    infringement, a 50% chance of prevailing with respect to
    validity, and a 90% chance of prevailing with respect to
    inequitable conduct. 60 Because Andrx would have to prevail
    with respect to all three issues in order to win the case,
    Adelman concluded that “Andrx had approximately a one out
    of three chance of winning the cases.” 61 (JA 38717.)
    60
    Adelman’s estimates and analysis are uncontested.
    61
    The probability that Andrx would prevail on all
    three issues was calculated by multiplying the probability of
    success on each issue.         0.8*0.9*0.5=0.36, which is
    approximately 1/3.
    74
    However, in a bit of historical irony, it was Anchen’s founder
    and CEO who made the invention disclosed in the ’708
    patent, and he assigned his rights in it to Andrx. Accordingly,
    it is highly likely that assignor estoppel would have prevented
    Anchen from arguing that the ’708 patent was invalid or that
    the patent was unenforceable because of inequitable
    conduct. 62 Mentor Graphics Corp. v. Quickturn Design Sys.,
    Inc., 
    150 F.3d 1374
    , 1378-79 (Fed. Cir. 1998) (describing the
    doctrine of assignor estoppel and explaining that the doctrine
    “also prevents parties in privity with an estopped assignor
    from challenging the validity of the patent”); Shamrock
    Techs., Inc. v. Med. Sterilization, Inc., 
    903 F.2d 789
    , 793
    (Fed. Cir. 1990) (same). As a result, the only topic left for
    litigation would be whether Anchen infringed. On that point,
    Adelman’s unrebutted analysis was that Andrx would have an
    62
    “Assignor estoppel prevents a party who assigns a
    patent to another from later challenging the validity of the
    assigned patent. This doctrine prevents the unfairness and
    injustice of permitting a party to sell something and later to
    assert that what was sold is worthless. ... [A]n assignment
    contains an implicit representation by the assignor that the
    patent rights that he is assigning ... are not worthless.”
    Mentor Graphics Corp., v. Quickturn Design Sys., Inc., 
    150 F.3d 1374
    , 1378 (Fed. Cir. 1998) (internal quotation marks
    and citations omitted); see Shamrock Techs., Inc. v. Med.
    Sterilization, Inc., 
    903 F.2d 789
    , 793 (Fed. Cir. 1990)
    (explaining assignor estoppel also applies to those who are in
    privity with the assignor). Because the estoppel applies not
    only to the individual inventor but also to those in privity,
    Anchen itself, and not just its founder and CEO, would likely
    have been estopped.
    75
    80% chance of proving infringement – or, in other words, that
    Anchen would only have a 20% chance of winning the suit. 63
    Neither the Appellants nor GSK identify any other evidence
    in the record that speaks to the possible outcomes of the
    Anchen-Andrx litigation. On this record, then, no reasonable
    jury could conclude that Anchen would have been more likely
    than not to prevail.
    Because both of the scenarios advanced by the
    Appellants fail to show that Anchen would have been able to
    launch its 150 mg version of Wellbutrin XL without running
    afoul of the Andrx patent, we conclude that the Appellants
    have also failed to show that their injuries were caused by the
    overall settlement. Because the Appellants thus do not have
    antitrust standing, we will affirm the District Court’s grant of
    summary judgment. 64
    63
    The Appellants’ only response to that analysis is that
    GSK never moved for summary judgment on inventor
    estoppel and that Anchen had not raised the issue of assignor
    estoppel before it settled the case. Even if those assertions
    are true, they do not show that Andrx would not have asserted
    the estoppel argument as the case progressed.
    64
    Having concluded that the Appellants lack antitrust
    standing, we do not need to consider the District Court’s
    application of the rule of reason. We note, however, that the
    rule of reason inquiry is fact intensive and is not easy to
    resolve at the summary judgment stage. See Poller v.
    Columbia Broad. Sys., Inc., 
    368 U.S. 464
    , 473 (1962)

    225 F.3d 350
    , 353 n.3 (3d Cir. 2000)
    (“We do not reach the class certification issue raised by
    Wilson since we [will] affirm the District Court’s dismissal of
    the complaint ... .”).
    and hostile witnesses thicken the plot.”); W. Penn Allegheny
    Health 
    Sys., 627 F.3d at 99
    (describing the rule-of-reason as
    “fact intensive”); cf. 
    King, 791 F.3d at 411
    n.36 (describing
    the significance of fact finding in the rule of reason analysis).
    65
    To recap, those issues are the decisions excluding
    the testimony of their economic expert and denying Aetna’s
    motion to intervene. Additionally, the indirect-purchaser
    Appellants challenge the District Court orders decertifying
    the indirect-purchaser class and dismissing certain of the
    indirect purchasers’ claims for lack of standing. Finally, GSK
    conditionally cross-appeals the Court’s certification of the
    direct-purchaser class as well as the Court’s conclusion that
    the indirect purchasers satisfy the predominance requirement
    of Rule 23.
    77
    III.   Conclusion
    For the foregoing reasons, we will affirm the District
    Court’s grant of summary judgment.
