    OPINION OF THE COURT
    ____________
    SLOVITER, Circuit Judge.
    In this appeal, we consider the antitrust implications of
    an agreement by a manufacturer of a generic drug that, in
    return for a payment by the patent holder, agrees to drop its
    challenge to the patent and refrain from entering the market
    for a specified period of time.
    A secondary issue concerns the certification by the
    District Court of a class of antitrust plaintiffs. Specifically,
    we must determine whether the antitrust injury allegedly
    suffered by class members can be shown through common
    proof, i.e. proof applicable to all plaintiffs, and whether there
    are insurmountable conflicts preventing named plaintiffs from
    adequately representing the members of the class.
    These appeals arise out of the settlement of two patent
    cases involving the drug K-Dur 20 (“K-Dur”), which is
    manufactured by Schering-Plough Corporation (“Schering”).
    Plaintiffs are Louisiana Wholesale Drug Company, Inc., on
    behalf of a class of wholesalers and retailers who purchased
    K-Dur directly from Schering and nine individual plaintiffs,
    including CVS Pharmacy, Inc., Rite Aid Corporation, and
    other pharmacies. Defendants are Schering and Upsher-
    Smith Laboratories (“Upsher Smith”). 1
    1
    In appeals numbered 10-2077, 10-2078, and 10-2079,
    Appellants challenge the District Court’s grant of summary
    judgment on behalf of defendants, relying on their patents. In
    No. 10-4571, defendants challenge the District Court’s
    certification of a class of plaintiffs.
    6
    I.     STATUTORY AND REGULATORY
    FRAMEWORK
    K-Dur is Schering’s brand-name sustained-release
    potassium chloride supplement. 2 Sustained-release potassium
    chloride is used to treat potassium deficiencies, including
    those that arise as a side effect of the use of diuretic products
    to treat high blood pressure.
    Schering did not hold a patent for the potassium
    chloride salt itself, as that compound is commonly known and
    not patentable. Instead, Schering held a formulation patent on
    the controlled release coating it applied to the potassium
    chloride crystals. Schering identified patent number
    4,863,743 (“the ‘743 patent”) as the patent that would be
    infringed by the production of a generic version of K-Dur.
    Schering assigned the ‘743 patent to its subsidiary Key
    Pharmaceuticals, Inc. The ‘743 patent was set to expire on
    September 5, 2006.
    By statute, a pharmaceutical company must obtain
    from the Food and Drug Administration (“FDA”) approval
    before it may market a prescription drug. 
    21 U.S.C. § 355
    (a).
    For a new drug, the approval process requires submission of a
    New Drug Application (“NDA”), which includes exhaustive
    information about the drug, including safety and efficacy
    studies, the method of producing the drug, and any patents
    issued on the drug’s composition or methods of use. 
    Id.
     §
    355(b)(1). The FDA publishes the patent information
    submitted in NDAs in the “Approved Drug Products with
    Therapeutic Equivalence Evaluations,” otherwise known as
    the “Orange Book.” See FDA Electronic Orange Book,
    http://www.fda.gov/cder/ob/.
    In 1984, attempting to jumpstart generic competition
    with name brand pharmaceuticals, Congress passed the Drug
    2
    After the facts at issue in this case, Merck & Co.
    acquired Schering, the named defendant in these actions.
    However, in keeping with the practice of the parties and
    amici, the court will refer to Schering.
    7
    Price Competition and Patent Term Restoration Act,
    commonly known as the Hatch-Waxman Act. Pub. L. No.
    98-417, 
    98 Stat. 1585
     (1984). The Hatch-Waxman Act
    amended the Federal Food, Drug, and Cosmetic Act, 
    21 U.S.C. §§ 301-399
    , to permit a potential manufacturer of a
    generic version of a patented drug to file an abbreviated
    application for approval with the FDA. See 
    21 U.S.C. § 355
    (j). This short form application, known as an Abbreviated
    New Drug Application (“ANDA”), may rely on the FDA’s
    prior determinations of safety and efficacy made in
    considering the application of the patented drug. 
    Id.
     §
    355(j)(2)(A).
    When a generic manufacturer files an ANDA, it is also
    required to file a certification that, “in the opinion of the
    applicant and to the best of his knowledge,” the proposed
    generic drug does not infringe any patent listed with the FDA
    as covering the patented drug. Id. § 355(j)(2)(A)(vii). The
    generic manufacturer can satisfy this requirement by
    certifying one of the following four options with respect to
    the patent for the listed drug: “(I) that such patent
    information has not been filed, (II) that such patent has
    expired, (III) [by certifying] the date on which such patent
    will expire, or (IV) that such patent is invalid or will not be
    infringed by the manufacture, use, or sale of the new drug for
    which the application is submitted.” Id. § 355(j)(2)(A)(vii).
    The generic manufacturers at issue here, Upsher and ESI,
    used the fourth of these certification options, the so-called
    “paragraph IV certification.” Id. § 355(j)(2)(A)(vii)(IV).
    When a would-be generic manufacturer submits a paragraph
    IV certification, it must consult the Orange Book and provide
    written notice to each listed patent owner impacted by the
    ANDA. Id. § 355(j)(2)(B)(iii)(I). By statute, a paragraph IV
    certification constitutes a technical act of patent infringement.
    
    35 U.S.C. § 271
    (e)(2)(A).
    Upon receiving notice of a paragraph IV certification
    with respect to one of its pharmaceutical patents, the patent
    holder may initiate an infringement suit based on the filing of
    the paragraph IV certification alone within forty-five days
    after the generic applicant files its ANDA and paragraph IV
    8
    certification. 
    21 U.S.C. § 355
    (j)(5)(B)(iii). Filing suit by the
    patent holder within that window effects an automatic stay
    that prevents the FDA from approving the generic drug until
    the earlier of (1) thirty months have run or (2) the court
    hearing the patent challenge finds that the patent is either
    invalid or not infringed. 
    Id.
     § 355(j)(5)(B)(iii)(I).
    Congress explained that the purpose of the Hatch-
    Waxman Act is “to make available more low cost generic
    drugs.” H.R. Rep. No. 98-857(I), at 14-15, reprinted in 1984
    U.S.C.C.A.N. 2647, 2647-48. In order to encourage generic
    entry and challenges to drug patents, the Hatch-Waxman Act
    rewards the first generic manufacturer who submits an
    ANDA and a paragraph IV certification by providing it with a
    180-day period during which the FDA will not approve
    subsequent ANDA applications. 
    21 U.S.C. § 355
    (j)(5)(B)(iv). The 180-day exclusivity period is triggered
    on the date on which the first ANDA applicant begins
    commercial marketing of its drug. 
    Id.
     Notably, the 180-day
    exclusivity window is only available to the first filer of an
    ANDA with a paragraph IV certification, meaning that even
    if the first filer never becomes eligible to use its 180-day
    exclusivity period because it settles, loses, or withdraws the
    litigation, that potential benefit will not pass to subsequent
    filers. 
    21 U.S.C. § 355
    (j)(5)(D)(iii). It has been suggested
    that the first filer is usually the most motivated challenger to
    the patent holder’s claimed intellectual property. See C. Scott
    Hemphill, Paying for Delay: Pharmaceutical Patent
    Settlement as a Regulatory Design Problem, 
    81 N.Y.U. L. Rev. 1553
    , 1583 (2006) (noting “a sharp difference in
    incentives . . . between [the first paragraph IV] filer and all
    other generic firms”).
    As explained further below, in the years after the
    passage of Hatch-Waxman, some of the patent infringement
    suits occurring under the Hatch-Waxman framework were
    resolved through settlement agreements in which the patent
    holder paid the would-be generic manufacturer to drop its
    patent challenge and refrain from producing a generic drug
    for a specified period. These agreements are known as
    “reverse payment agreements” or “exclusion agreements.”
    9
    Concerned about the possible anticompetitive effects of
    reverse payment agreements, see S. Rep. No. 107-167, at 4
    (2002), Congress amended Hatch-Waxman as part of the
    Medicare Prescription Drug, Improvement, and
    Modernization Act of 2003. Those amendments require
    branded and generic pharmaceutical companies who enter
    into patent litigation settlements to file those settlement
    agreements with the Federal Trade Commission (“FTC”) and
    the Department of Justice (“DOJ”) for antitrust review. Pub.
    L. No. 108-173, §§ 1111-1118, 
    117 Stat. 2066
    , 2461-64
    (codified as amended at 
    21 U.S.C. § 355
    (j)).
    II.    FACTUAL AND PROCEDURAL
    BACKGROUND
    A. Approval of the ‘743 Patent
    The patented invention claims a controlled-release
    dispersible potassium chloride tablet. The ‘743 patent was
    developed using a technique called “microencapsulation,” a
    process in which small particles of a drug are coated to make
    them disperse over time. The research supporting the ‘743
    patent built on work that Schering had done for an earlier
    patent for a controlled-release aspirin tablet, Patent No.
    4,555,399 (“the ‘399 patent”). The application for what
    became the ‘743 patent was initially rejected by the Patent
    and Trademark Office (“PTO”) as obvious in light of the ‘399
    patent and other prior art. In order to circumvent the prior art,
    Schering amended its application for what became the ‘743
    patent to clarify that the controlled release coating in the
    invention contained ethylcellulose with a viscosity of greater
    than 40 cp, 3 whereas the ‘399 patent called for the use of
    ethylcellulose with a viscosity of 9-11 cp. Schering argued
    that a coating containing ethylcellulose of greater than 40 cp
    was not obvious under the prior art. After this amendment,
    the PTO granted the ‘743 patent on September 5, 1989.
    3
    Centipoise, abbreviated “cp”, is a measure of viscosity.

    10
    B. The Schering-Upsher Litigation and
    Settlement
    In August 1995, Upsher filed the first ANDA seeking
    approval to produce a generic version of K-Dur to be called
    Klor-Con M20. Upsher provided a paragraph IV certification
    to Schering in November 1995, certifying that its generic
    would not infringe Schering’s ‘743 patent. On December 15,
    1995, within the forty-five-day window provided by Hatch-
    Waxman, Schering sued Upsher in the District of New Jersey
    for patent infringement, triggering the 30-month automatic
    stay in FDA approval of Upsher’s generic.
    Upsher’s defense against Schering’s patent
    infringement suit was based on differences between the
    chemical composition of the controlled release coating in its
    generic product and that of the invention claimed in the ‘743
    patent. Throughout the litigation, Upsher vigorously
    defended against Schering’s infringement claims, at one point
    telling the court that Schering’s claims of infringement “are
    baseless and could not have been made in good faith.” App.
    at 3610.
    The parties began trying to settle the infringement case
    at least as early as May 1997. During settlement negotiations,
    Upsher requested both a cash payment and an early entry date
    for its generic product. However, Schering expressed
    concern about possible antitrust problems that might arise if it
    made a reverse payment.
    In the early morning of June 18, 1997, just hours before
    the District Court was to rule on the pending cross motions for
    summary judgment and begin, if necessary, a patent trial,
    Upsher and Schering agreed to settle the case. The settlement
    was memorialized in an eleven-page short-form agreement dated
    June 17, 1997 (“the Schering-Upsher agreement”). That
    agreement provided that, while Upsher did not concede the
    validity, infringement, or enforceability of the ‘743 patent, it
    would refrain from marketing its generic potassium chloride
    supplement or any similar product until September 1, 2001, at
    which point it would receive a non-royalty non-exclusive license
    11
    under the ‘743 patent to make and sell a generic form of Klor-
    Con. Additionally, Upsher granted Schering licenses to make
    and sell several pharmaceutical products Upsher had developed,
    including Niacor-SR, a sustained-release niacin product used to
    treat high cholesterol. In return, Schering promised to pay
    Upsher sixty million dollars ($60,000,000) over three years, plus
    additional smaller sums depending upon its sales of Niacor-SR
    in defined markets. While the parties to this litigation dispute
    whether the payment was solely for the licensing of Upsher
    products or instead formed part of the consideration for
    dropping the patent action, the agreement lists Upsher’s
    promises to dismiss the patent infringement action and not to
    market any sustained-release microencapsulated potassium
    chloride tablet until September 1, 2001, as part of the
    consideration for the payment.
    The settlement agreement and the acquisition of
    licenses from Upsher were ratified by Schering’s board of
    directors on June 24, 1997. Subsequent to the settlement,
    Upsher and Schering abandoned plans to make and market
    Niacor-SR.
    In this action, the parties dispute the facts related to the
    Niacor-SR license. Plaintiffs contend that the license was a
    sham and that the $60 million paid as royalties for Niacor-SR
    was actually compensation for Upsher’s agreement to delay
    the entry of its generic extended-release potassium tablet. On
    the other hand, defendants contend that Schering’s board
    valued the license deal separately and that $60 million was its
    good faith valuation of the licenses at the time.
    C. The Schering-ESI Litigation and
    Settlement
    In December 1995, ESI Lederle 4 (“ESI”) filed an
    ANDA seeking FDA approval to make and sell a generic
    4
    ESI is the generic division of American Home Products,
    Inc., which changed its name to Wyeth in 2002. Melody
    Peterson, American Home Is Changing Name to Wyeth, New
    York Times, Mar. 11, 2002. Wyeth was subsequently
    12
    version of K-Dur along with a paragraph IV certification
    stating that its proposed generic did not infringe the ‘743
    patent. Within the forty-five-day period provided by the
    Hatch-Waxman Act, Schering sued ESI for patent
    infringement in the Eastern District of Pennsylvania. ESI
    defended on the ground that, unlike K-Dur, its generic
    equivalent did not employ a “coating material with two
    different ingredients” as specified by the ‘743 patent, but
    rather was made by a “different technology which produces a
    multi-layered coating with each layer comprised of a separate
    material having only a single ingredient.” App. at 1696-97.
    In the fall of 1996, Schering and ESI agreed to
    participate in court-supervised mediation before a magistrate
    judge. The settlement agreement the parties eventually
    reached (“the Schering-ESI agreement”) called for Schering
    to grant ESI a royalty-free license under the ‘743 patent
    beginning on January 1, 2004. In exchange, Schering would
    pay ESI $5 million up front and a varying sum depending on
    when ESI’s ANDA was approved by the FDA. Specifically,
    Schering agreed to pay ESI an amount ranging from a
    maximum of $10 million if ESI’s ANDA was approved
    before July 1999 down to a minimum of $625,000 if the
    ANDA was not approved until 2002. As part of the
    settlement, ESI also represented that it was not developing
    and had no plans to develop any other potassium chloride
    product.
    The FDA approved ESI’s generic K-Dur product in
    May 1999, and Schering paid ESI the additional $10 million
    as required under the settlement agreement.
    D. The FTC Action
    acquired by Pfizer, Inc. in 2009. Pfizer, “Wyeth
    Transaction,” http://www.pfizer.com/investors/
    shareholder_services/wyeth_transaction.jsp (last visited May
    8, 2012). Plaintiffs settled their claims against ESI’s
    corporate parent Wyeth in January 2005.
    13
    In March 2001, the FTC filed a complaint against
    Schering, Upsher, and ESI alleging that Schering’s
    settlements with Upsher and ESI unreasonably restrained
    commerce in violation of Section 5 of the Federal Trade
    Commission Act, 
    15 U.S.C. § 45
    . Specifically, the FTC
    alleged that the settlement payments from Schering to Upsher
    and ESI constituted reverse payments intended to delay
    generic entry and improperly preserve Schering’s monopoly.
    In June 2002, after a lengthy trial, the Administrative
    Law Judge (“ALJ”) issued an initial decision dismissing the
    FTC’s complaint and finding that neither agreement violated
    Section 5 of the FTC Act. In re Schering-Plough Corp.,
    Initial Decision, 
    136 F.T.C. 1092
    , 1263 (2002). The ALJ
    found that there was no reverse payment in the Schering-
    Upsher agreement because the licensing deal included in that
    agreement was separately valued and was not a payment to
    Upsher to delay generic entry. 
    Id. at 1243
    . The ALJ also
    found that the Schering-ESI agreement was not an attempt to
    unlawfully preserve Schering’s monopoly power in the
    market. 
    Id. at 1236, 1262-63
    .
    In December 2003, the FTC unanimously reversed the
    ALJ’s ruling, finding that there was a “direct nexus between
    Schering’s payment and Upsher’s agreement to delay its
    competitive entry” and that this agreement “unreasonably
    restrain[ed] commerce.” In re Schering-Plough Corp., Final
    Order, 
    136 F.T.C. 956
    , 1052 (2003). The FTC likewise found
    that the ESI settlement violated antitrust law, noting that
    Schering had not attempted to rebut the natural presumption
    that the payment to ESI was for delay in generic entry, except
    to argue unpersuasively that the parties felt judicial pressure
    to settle. 
    Id. at 1056-57
    . In making these determinations, the
    FTC found that it was “neither necessary nor helpful to delve
    into the merits of the [underlying patent disputes].” 
    Id. at 1055
    . Rather, the FTC determined that, where a name brand
    pharmaceutical maker pays a generic manufacturer as part of
    a settlement, “[a]bsent proof of other offsetting consideration,
    it is logical to conclude that the quid pro quo for the payment
    was an agreement by the generic to defer entry beyond the
    date that represents an otherwise reasonable litigation
    14
    compromise.” 
    Id. at 988
    . In applying the rule of reason, the
    FTC concluded that the possible existence of a reverse
    payment raises a red flag and can give rise to a prima facie
    case that an agreement is anticompetitive. 
    Id. at 991
    , 1000-
    01. The FTC concluded that the reverse payment at issue was
    illegal because the settling parties could show neither (1) that
    the payment was for something other than delay of generic
    entry nor (2) that the payment had pro-competitive effects.
    
    Id. at 988-89, 1061
    .
    Schering appealed the FTC’s ruling to the Eleventh
    Circuit, which reversed in Schering-Plough Corp. v. FTC,
    
    402 F.3d 1056
     (11th Cir. 2005). The Eleventh Circuit’s
    ruling in Schering-Plough is discussed in Section III(C) infra.
    E. The Instant Litigation
    Separate from the FTC’s challenge, various private
    parties filed antitrust suits attacking the settlements. Those
    suits, the matters giving rise to this appeal, were
    consolidated in the District of New Jersey by the Judicial
    Panel on Multidistrict Litigation. In 2006, by consent of the
    parties, the District Court appointed Stephen Orlofsky as
    Special Master with responsibility to handle all motions,
    including motions for class certification and summary
    judgment. 5
    5
    Because there was no objection to the appointment of a
    Special Master, we have no occasion to address the use of
    Special Master to prepare Reports and Recommendations on
    summary judgment motions. See In re Bituminous Coal
    Operators’ Ass’n, Inc., 
    949 F.2d 1165
    , 1168 (D.C. Cir. 1991)
    (“Rule 53 of the Federal Rules of Civil Procedure authorizes
    the appointment of special masters to assist, not to replace,
    the adjudicator, whether judge or jury, constitutionally
    indicated for federal court litigation.”) (emphasis in original)
    (citing La Buy v. Howes Leather Co., Inc., 
    352 U.S. 249
    , 256
    (1957)).
    15
    On April 14, 2008, the Special Master certified a class
    of plaintiffs consisting of forty-four wholesalers and retailers
    who purchased K-Dur directly from Schering. The District
    Court adopted that decision on December 30, 2008. 6
    In February 2009, the Special Master issued a Report
    and Recommendation granting defendants’ motions for
    summary judgment and denying plaintiffs’ motions for partial
    summary judgment. In his Report and Recommendation, the
    Special Master applied a presumption that Schering’s ‘743
    patent was valid and that it gave Schering the right to exclude
    infringing products until the end of its term, including
    through reverse payment settlements. Under this analysis, the
    settlements in this case would only be subject to antitrust
    scrutiny if (1) they exceeded the scope of the ‘743 patent or
    (2) the underlying patent infringement suits were objectively
    baseless. The Special Master determined that neither of these
    exceptions applied. The District Court subsequently adopted
    the Report and Recommendation in its entirety.
    F. Economic Background and the History
    of Reverse Payment Settlements
    Reverse payment settlements appear to be unique to
    the Hatch-Waxman context, and the FTC has made them a
    top enforcement priority in recent years. A 2010 analysis by
    the FTC found that reverse payment settlements cost
    consumers $3.5 billion annually. FTC, Pay-for-Delay: How
    Drug Company Pay-Offs Cost Consumers Billions 2 (2010),
    available at http://www.ftc.gov/os/2010/01/100112
    payfordelayrpt.pdf. The FTC estimates that about one year
    after market entry an average generic pharmaceutical product
    takes over ninety percent of the patent holder’s unit sales and
    sells for fifteen percent of the price of the name brand
    product. Id. at 8. This price differential means that
    consumers, rather than generic producers, are typically the
    biggest beneficiaries of generic entry.

    The class certification decision is discussed in Section
    IV infra.

    III.   THE ANTITRUST ISSUE (Appeals Nos.
    10-2077, 10-2078, 10-2079)
    A. Jurisdiction and Standard of Review
    The District Court had jurisdiction pursuant to 
    15 U.S.C. § 15
    (a) and 
    28 U.S.C. §§ 1331
     and 1337. This court
    has jurisdiction over the antitrust appeals pursuant to 
    28 U.S.C. § 1291
    .
    This court exercises plenary review of the District
    Court’s grant of summary judgment, applying the same
    summary judgment standard that guides the District Court.
    Eichenlaub v. Twp. of Indiana, 
    385 F.3d 274
    , 279 (3d Cir.
    2004).
    B. General Antitrust Standard
    The Sherman Act provides, in part, that “[e]very
    contract, combination in the form of trust or otherwise, or
    conspiracy, in restraint of trade or commerce among the
    several States, or with foreign nations, is declared to be
    illegal.” 
    15 U.S.C. § 1
    . Under a literal reading, this provision
    would make illegal every agreement in restraint of trade. See
    Arizona v. Maricopa Cnty. Med. Soc’y, 
    457 U.S. 332
    , 342
    (1982). However, it has not been so interpreted. Rather the
    Supreme Court has long construed it to prohibit only
    unreasonable restraints. See State Oil Co. v. Khan, 
    522 U.S. 3
    , 10 (1997). Whether a restraint qualifies as unreasonable
    and therefore conflicts with the statute is normally evaluated
    under the “rule of reason.” 
    Id.
     Applying this approach, “the
    finder of fact must decide whether the questioned practice
    imposes an unreasonable restraint on competition, taking into
    account a variety of factors, including specific information
    about the relevant business, its condition before and after the
    restraint was imposed, and the restraint’s history, nature, and
    effect.” 
    Id.
     This inquiry has been divided into three parts.
    First, the plaintiff must show that the challenged conduct has
    produced anti-competitive effects within the market. United
    States v. Brown Univ., 
    5 F.3d 658
    , 668 (3d Cir. 1993). If the
    plaintiff meets the initial burden, “the burden shifts to the
    17
    defendant to show that the challenged conduct promotes a
    sufficiently pro-competitive objective.” 
    Id. at 669
    . Finally,
    the plaintiff can rebut the defendant’s purported pro-
    competitive justification by showing that the restraint is not
    reasonably necessary to achieve the pro-competitive
    objective. 
    Id.
    Courts have recognized, however, that “[s]ome types
    of restraints . . . have such predictable and pernicious
    anticompetitive effect, and such limited potential for
    pro-competitive benefit, that they [should be] deemed
    unlawful per se.” State Oil Co., 
    522 U.S. at 10
    . Examples of
    agreements that have been held unlawful pursuant to the per
    se rule include horizontal price fixing, output limitations,
    market allocation, and group boycotts. See Copperweld
    Corp. v. Independence Tube Corp., 
    467 U.S. 752
    , 768 (1984);
    N. Pac. Ry. v. United States, 
    356 U.S. 1
    , 5 (1958). The per se
    rule is applied where a “practice facially appears to be one
    that would always or almost always tend to restrict
    competition or decrease output.” Broad. Music, Inc. v. CBS,
    Inc., 
    441 U.S. 1
    , 19-20 (1979).
    In some situations, courts apply an antitrust analysis
    that falls between the full rule of reason inquiry on the one
    hand and the rigid per se approach on the other. This so-
    called “quick look” or “truncated rule of reason” analysis
    applies where the plaintiff has shown that the defendant has
    engaged in practices similar to those subject to per se
    treatment. See Brown Univ., 
    5 F.3d at 669
    . Having so
    shown, plaintiff is not required to make a full showing of
    anti-competitive effects within the market; rather defendant
    has the burden of demonstrating pro-competitive
    justifications. 
    Id.
    C. Precedent from Other Circuits
    Neither this court nor the Supreme Court has yet
    weighed in on the legality of reverse payment settlements.
    However, five other circuits have addressed the question.
    Two of those courts – the first two to consider the question –
    concluded that such agreements should be subject to strict
    18
    antitrust scrutiny, at least where the settling parties attempted
    to manipulate the 180-day exclusivity period to block all
    potential generic competition. The three courts to address the
    question of reverse payments more recently have reached a
    contrary result, ruling that such agreements are permissible so
    long as they do not exceed the potential exclusionary scope of
    the patent.
    1. D.C. Circuit – Andrx Pharms., Inc. v.
    Biovail Corp. Int’l, 
    256 F.3d 799
    (D.C. Cir. 2001)
    The D.C. Circuit considered a reverse payment in
    Andrx Pharmaceuticals, Inc. v. Biovail Corp. International,
    
    256 F.3d 799
     (D.C. Cir. 2001), cert. denied, 
    535 U.S. 931
    (2002). Unlike the instant case, that case did not involve a
    settlement resolving patent litigation. Rather, while allowing
    the patent litigation to continue, the name brand manufacturer
    agreed to compensate the would-be generic producer to delay
    marketing a generic product.
    In September 1995, Andrx Pharmaceuticals (“Andrx”)
    filed an ANDA seeking to manufacture and sell a generic
    form of Cardizem CD, a heart drug for which Hoechst Marion
    Russell, Inc. (“HMRI”) held the patent. 
    Id. at 803
    . Andrx
    filed a paragraph IV certification and was timely sued for
    patent infringement by HMRI. 
    Id.
     The filing of the patent
    infringement suit triggered the thirty-month waiting period
    during which the FDA could not give final approval to Andrx
    or any subsequent ANDA applicants seeking to make a
    generic version of Cardizem CD. 
    Id.
     (citing 
    21 U.S.C. § 355
    (j)(5)(B)(iii)). In June 1997, a second generic
    manufacturer, Biovail Corp. International (“Biovail”), filed an
    ANDA and a paragraph IV certification to produce generic
    Cardizem CD. Shortly thereafter, the FDA issued a tentative
    approval of Andrx’s ANDA. 
    Id.
    Soon after the tentative approval was issued, HMRI
    and Andrx entered into an agreement pursuant to which
    HMRI would pay Andrx $40 million per year beginning on
    the date that Andrx received final approval from the FDA and
    19
    ending on the date that Andrx either began selling generic
    Cardizem CD or was adjudged liable for patent infringement
    in the pending suit. 
    Id.
     The apparent purpose of this
    agreement was to create a bottleneck by delaying the
    triggering of Andrx’s 180-day period of exclusivity, and
    thereby delaying generic entry not only by Andrx but also by
    any other potential generic manufacturer. 
    Id. at 804
    .
    The D.C. Circuit reversed the district court’s dismissal
    with prejudice of Biovail’s antitrust claims, holding that the
    agreement between HMRI and Andrx could “reasonably be
    viewed as an attempt to allocate market share and preserve
    monopolistic conditions.” 
    Id. at 811
    . The D.C. Circuit
    treated the payment from HMRI to Andrx as prima facie
    evidence of an illegal agreement not to compete, noting that
    “Andrx’s argument that any rational actor would wait for
    resolution of the patent infringement suit [before triggering
    the 180-day exclusivity period] is belied by the quid of
    HRMI’s quo.” 
    Id. at 813
    .
    2. Sixth Circuit – In re Cardizem CD
    Antitrust Litig., 
    332 F.3d 896
     (6th
    Cir. 2003)
    The Sixth Circuit’s decision of In re Cardizem CD
    Antitrust Litigation concerned the same agreement considered
    by the D.C. Circuit in Andrx. 
    332 F.3d 896
     (6th Cir. 2003),
    cert. denied, 
    543 U.S. 939
     (2004). The Sixth Circuit case was
    brought by direct and indirect purchasers of Cardizem CD
    who alleged that they suffered antitrust harm as a result of
    Andrx’s agreement with HRMI to delay market entry. 
    Id. at 903-04
    . The Sixth Circuit held that the Andrx-HRMI
    agreement was “a horizontal agreement to eliminate
    competition in the market for Cardizem CD throughout the
    entire United States, a classic example of a per se illegal
    restraint of trade.” 
    Id. at 908
    .
    While both Cardizem and Andrx concerned an
    agreement that caused a bottleneck by preventing other
    generic manufactures from entering the market by delaying
    the triggering of the first filer’s 180-day exclusivity period,
    20
    much of the Sixth Circuit’s reasoning in Cardizem is equally
    applicable to cases, like the instant one, that do not involve
    bottlenecking. Specifically, the Sixth Circuit emphasized its
    concern that, even setting aside the bar to subsequent generic
    applicants, HMRI had paid Andrx not to enter the market
    itself, stating, “it is one thing to take advantage of a monopoly
    that naturally arises from a patent, but another thing
    altogether to bolster the patent’s effectiveness in inhibiting
    competitors by paying the only potential competitor $40
    million per year to stay out of the market.” 
    Id. at 908
    .
    3. Eleventh Circuit – Valley Drug Co. v.
    Geneva Pharms., Inc., 
    344 F.3d 1294
    (11th Cir. 2003) and Schering-Plough
    Corp. v. FTC, 
    402 F.3d 1056
     (11th
    Cir. 2005)
    The Eleventh Circuit has also considered the question
    of reverse payments settlements in three significant cases.
    The first of these, Valley Drug Co. v. Geneva
    Pharmaceuticals, Inc., 
    344 F.3d 1294
     (11th Cir. 2003), cert.
    denied, 
    543 U.S. 939
     (2004), concerned two agreements
    arising out of cases where a name brand drug manufacturer
    sued generic manufacturers for patent infringement and the
    generic manufacturers defended on the ground of patent
    invalidity. 7 
    Id. at 1299-301
    . In the two agreements at issue,
    the name brand manufacturer agreed to pay the generic
    manufacturer substantial sums to refrain from entering the
    market until the end of the name brand manufacturer’s patent
    term. 
    Id. at 1300
    . The patent at issue was subsequently
    declared invalid in another case. 
    Id. at 1306-07
    . The district
    court granted summary judgment to antitrust plaintiffs,
    holding that the settlements were per se violations of the
    Sherman Act. 
    Id. at 1301
    . The Eleventh Circuit reversed on
    the ground that the name brand manufacturer held a patent
    that gave it the right to exclude competitors. 
    Id. at 1306
    . In
    7
    One of these agreements was a final settlement of certain
    claims, the other was structured, like the agreements in Andrx
    and Cardizem, to take effect even as the litigation continued.
    See Valley Drug, 
    344 F.3d at 1300
    .
    21
    so ruling, the court emphasized the fact that the name brand
    manufacturer might have prevailed in the underlying patent
    litigation, 
    id. at 1309
    , and highlighted policy considerations
    favoring the settlement of patent litigation, 
    id.
     at 1308 n.20.
    The court applied neither a per se nor rule of reason analysis
    to the agreements as a whole; rather, it directed the district
    court to first determine whether any part of the agreement
    went beyond the protections afforded by the name brand
    manufacturer’s patent and, if so, to apply traditional antitrust
    scrutiny only to those portions of the agreement. 
    Id.
     at 1311-
    1312.
    A subsequent Eleventh Circuit case, Schering-Plough
    Corp. v. FTC, arose out of the same settlement agreement as
    the instant appeal. 8 
    402 F.3d 1056
     (11th Cir. 2005), cert.
    denied, 
    548 U.S. 919
     (2006). After the FTC found that both
    agreements violated antitrust laws, the defendants appealed to
    the Eleventh Circuit. Applying the test articulated in Valley
    Drug, the Eleventh Circuit set aside the ruling of the FTC. 
    Id. at 1065-66, 1076
    . The court rejected the FTC’s conclusion
    that Schering’s $60 million payment to Upsher was for
    something other than the licenses it obtained, finding by
    “overwhelming evidence” that the payment was only for the
    licenses. 
    Id. 1069-71
    . As such, the court found that there
    was no reverse payment from Schering to Upsher and thus
    necessarily no antitrust violation in that agreement. 
    Id.
     With
    respect to the ESI settlement, the court acknowledged the
    8
    Defendants argue in passing that this court should begin
    its analysis in this case with a strong presumption in favor of
    following the Eleventh Circuit’s decision in Schering-Plough.
    However, none of the cases cited by defendants employs such
    a presumption; rather, they stand for the unsurprising
    proposition that this court will follow the decisions of its
    sister courts where it finds them persuasive. See, e.g.,
    Ramadan v. Chase Manhattan Corp., 
    229 F.3d 194
    , 197-203
    (3d Cir. 2000) (following the rulings of other courts of appeal
    on similar facts but conducting an independent analysis). As
    explained below, we do not find the Eleventh Circuit’s
    decision in Schering-Plough persuasive, and thus decline to
    follow it.
    22
    presence of a reverse payment but concluded that the payment
    was acceptable in light of judicial policy favoring settlements
    and the court’s finding that the settlement terms “‘reflect[ed]
    a reasonable implementation’ of the protections afforded by
    patent law.” Id. at 1072 (quoting Valley Drug, 
    344 F.3d at 1312
    ). 9
    Plaintiffs construe Valley Drug and Schering-Plough
    as requiring courts to conduct an ex post evaluation of the
    strength of the underlying patent before determining whether
    the patent shields an agreement from antitrust scrutiny.
    However, following oral argument in this case, the Eleventh
    Circuit explicitly rejected that interpretation of its prior
    holdings. In FTC v. Watson Pharmaceuticals, Inc., the
    Eleventh Circuit clarified that its prior opinions did not call
    for an evaluation of the strength of the patent but rather only a
    determination whether, absent sham litigation or fraud in
    obtaining the patent, the settlement agreement exceeded the
    scope of the patent. FTC v. Watson Pharms, Inc., No. 10-
    12729, 
    2012 WL 1427789
    , at *11 n.8, *12 (11th Cir. Apr. 25,
    2012). Thus the standard applied by the Eleventh Circuit is
    identical to the scope of the patent test applied by the Second
    Circuit to which we now turn.
    4. Second Circuit – In re Tamoxifen
    Citrate Antitrust Litig., 
    466 F.3d 187
    (2d Cir. 2006)
    The Second Circuit’s decision of In re Tamoxifen
    Citrate Antitrust Litigation arose out of an agreement settling
    a patent infringement suit over the drug tamoxifen, then the
    most widely prescribed drug for the treatment of breast
    cancer. 
    466 F.3d 187
    , 190 (2d Cir. 2006), cert. denied, 
    551 U.S. 1144
     (2007). That settlement was reached while the
    patent case was on appeal after the district court had ruled the
    9
    The Eleventh Circuit subsequently applied, without
    further significant explication, the scope of the patent test
    announced in Valley Drug and Schering-Plough in another
    case, Andrx Pharmaceuticals, Inc. v. Elan Corporation, PLC,
    
    421 F.3d 1227
     (11th Cir. 2005).
    23
    patent invalid. 
    Id.
     The settlement called for the name brand
    manufacturer to grant the generic manufacturer a license to
    sell an unbranded version of tamoxifen and make a reverse
    payment of $21 million to the generic manufacturer. The
    settlement was contingent on obtaining a vacatur of the
    district court’s judgment holding the patent to be invalid,
    which was subsequently obtained. 
    Id.
    Affirming the district court’s dismissal of antitrust
    plaintiffs’ claims, the Second Circuit applied a presumption
    of patent validity and held that “there is no injury to the
    market cognizable under existing antitrust law, as long as
    competition is restrained only within the scope of the patent.”
    Id. at 213 (internal citations and quotation marks omitted).
    The only exceptions to this rule, the court held, occur where
    there is evidence that the patent was procured by fraud or that
    the enforcement suit was objectively baseless. Id. This test is
    commonly referred to as the “scope of the patent test” or the
    “Tamoxifen test.” The Second Circuit conceded that there
    was a potentially troubling result of such a rule in that “[t]he
    less sound the patent or the less clear the infringement, and
    therefore the less justified the monopoly enjoyed by the
    patent holder, the more a rule permitting settlement is likely
    to benefit the patent holder by allowing it to retain the
    patent.” Id. at 211. The court determined, however, that this
    risk was counterbalanced by the judicial preference for
    settlement. Id.
    In reaching this conclusion, the Second Circuit
    concluded that “the Hatch-Waxman Act created an
    environment that encourages [reverse payments]” because,
    unlike traditional infringement suits where the patent holder
    can negotiate by agreeing to forego the infringement damages
    it expects to recover, there usually are no infringement
    damages in Hatch-Waxman suits. Id. at 206. The Second
    Circuit thus reasoned that the “reverse payments” common in
    Hatch-Waxman suits are less troubling because they take the
    place of infringement damages that the patent holder might
    have otherwise waived in order to reach a settlement. Id.
    24
    Judge Pooler dissented from the decision in
    Tamoxifen, contending that the scope of the patent rule
    applied by the majority “is not soundly grounded in Supreme
    Court precedent and is insufficiently protective of the
    consumer interests safeguarded by the Hatch-Waxman Act
    and the antitrust laws.” Id. at 224 (Pooler, J., dissenting).
    Judge Pooler argued, inter alia, that judicial reevaluation of
    patent validity is a public good that reverse payment
    settlements undercut, id. at 225-26, and suggested that the
    proper antitrust standard is one of reasonableness considering
    all the circumstances affecting a restrictive agreement
    including (1) the strength of the patent as it appeared at the
    time of settlement, (2) the amount of the reverse payment, (3)
    the amount the generic manufacturer would have made during
    its 180-day exclusivity period, and (4) any ancillary anti-
    competitive effects of the agreement. Id. at 228.
    In a subsequent reverse payment case, Arkansas
    Carpenters Health & Welfare Fund v. Bayer AG, the Second
    Circuit applied the Tamoxifen standard and rejected an
    antitrust challenge to a Hatch-Waxman settlement involving a
    reverse payment. 
    604 F.3d 98
     (2d Cir. 2010), cert. denied,
    
    131 S. Ct. 1606
     (2011). However, the judges on the Arkansas
    Carpenters panel made clear that they thought that Tamoxifen
    was wrongly decided and invited appellants to petition for
    rehearing en banc. 
    Id. at 108-10
    . Among other things, the
    Arkansas Carpenters court noted its concern about evidence
    suggesting that the number of reverse payment settlements
    had increased dramatically in the wake of the Tamoxifen
    decision. 
    Id. at 109
    . Rehearing en banc was subsequently
    denied over a dissent from Judge Pooler. Ark. Carpenters
    Health & Welfare Fund v. Bayer AG, 
    625 F.3d 779
     (2d Cir.
    2010).
    5. Federal Circuit – In re Ciprofloxacin
    Hydrochloride Antitrust Litig., 
    544 F.3d 1323
     (Fed. Cir. 2008)
    In In re Ciprofloxacin Hydrochloride Antitrust
    Litigation the Federal Circuit considered a case related to
    those confronted by the Second Circuit in Arkansas
    25
    Carpenters. 
    544 F.3d 1323
     (Fed. Cir. 2008), cert. denied,
    
    129 S. Ct. 2828
     (2009). 10 The Federal Circuit applied the
    scope of the patent test explicated in Tamoxifen and other
    cases, stating, “[t]he essence of the inquiry is whether the
    agreements restrict competition beyond the exclusionary zone
    of the patent.” 
    Id. at 1336
    . The court further “agree[d] with
    the Second and Eleventh Circuits . . . that, in the absence of
    evidence of fraud before the PTO or sham litigation, the court
    need not consider the validity of the patent in the antitrust
    analysis of a settlement agreement involving a reverse
    payment.” 
    Id.
    D. Analysis
    While the first two courts of appeal to address the
    issue of reverse payments subjected those agreements to
    antitrust scrutiny, later courts have gravitated toward the
    scope of the patent test under which reverse payments are
    permitted so long as (1) the exclusion does not exceed the
    patent’s scope, (2) the patent holder’s claim of infringement
    was not objectively baseless, and (3) the patent was not
    procured by fraud on the PTO. The scope of the patent test
    was applied by the Special Master in this case and has been
    applied by at least one other district court in this circuit. See
    King Drug Co. of Florence, Inc. v. Cephalon, Inc., 
    702 F. Supp. 2d 514
    , 528-29, 533 (E.D. Pa. 2010) (applying scope of
    the patent test but denying defendants’ motion to dismiss
    where plaintiffs pleaded facts supporting their claim that the
    underlying patent suit was objectively baseless). As a
    practical matter, the scope of the patent test does not subject
    reverse payment agreements to any antitrust scrutiny. As the
    antitrust defendants concede, no court applying the scope of
    the patent test has ever permitted a reverse payment antitrust
    case to go to trial.
    10
    That case was severed by the Second Circuit and
    transferred to the Federal Circuit because it involved a claim
    arising out of patent law. See Order, No. 05-2863 (2d Cir.
    Nov. 7, 2007).
    26
    After consideration of the arguments of counsel, the
    conflicting decisions in the other circuits, the Report of the
    Special Master, and our own reading, we cannot agree with
    those courts that apply the scope of the patent test. In our
    view, that test improperly restricts the application of antitrust
    law and is contrary to the policies underlying the Hatch-
    Waxman Act and a long line of Supreme Court precedent on
    patent litigation and competition.
    First, we take issue with the scope of the patent test’s
    almost unrebuttable presumption of patent validity. This
    presumption assumes away the question being litigated in the
    underlying patent suit, enforcing a presumption that the patent
    holder would have prevailed. We can identify no significant
    support for such a policy. While persons challenging the
    validity of a patent in litigation bear the burden of defeating a
    presumption of validity, this presumption is intended merely
    as a procedural device and is not a substantive right of the
    patent holder. See Stratoflex, Inc. v. Aeroquip Corp., 
    713 F.2d 1530
    , 1534 (Fed. Cir. 1983) (“The presumption, like all
    legal presumptions, is a procedural device, not substantive
    law.”). Moreover, the effectively conclusive presumption
    that a patent holder is entitled to exclude competitors is
    particularly misguided with respect to agreements – like those
    here – where the underlying suit concerned patent
    infringement rather than patent validity: In infringement cases
    it is the patent holder who bears the burden of showing
    infringement. See Egyptian Goddess, Inc. v. Swisa, Inc., 
    543 F.3d 665
    , 679 (Fed. Cir. 2008).
    Rather than adopt an unrebuttable presumption of
    patent validity, we believe courts must be mindful of the fact
    that “[a] patent, in the last analysis, simply represents a legal
    conclusion reached by the Patent Office.” Lear, Inc. v.
    Adkins, 
    395 U.S. 653
    , 670 (1969). Many patents issued by
    the PTO are later found to be invalid or not infringed, and a
    2002 study conducted by the FTC concluded that, in Hatch-
    Waxman challenges made under paragraph IV, the generic
    challenger prevailed seventy-three percent of the time. See
    FTC, Generic Drug Entry Prior to Patent Expiration 16
    (2002), available at http://www.ftc.gov/os/2002/07/
    27
    genericdrugstudy.pdf; Kimberly A. Moore, Judges, Juries,
    and Patent Cases – An Empirical Peek Inside the Black Box,
    
    99 Mich. L. Rev. 365
    , 385 (2000) (noting that between 1983
    and 1999 the alleged infringer prevailed in forty-two percent
    of patent cases that reached trial). 11 These figures add force
    to the likelihood – conceded by the Tamoxifen majority – that
    reverse payments enable the holder of a patent that the holder
    knows is weak to buy its way out of both competition with
    the challenging competitor and possible invalidation of the
    patent. 466 F.3d at 211 (“The less sound the patent or the less
    clear the infringement, and therefore the less justified the
    monopoly enjoyed by the patent holder, the more a rule
    permitting settlement is likely to benefit the patent holder by
    allowing it to retain the patent.”).
    Moreover, we question the assumption underlying the
    view of the Second Circuit and other courts that subsequent
    challenges by other generic manufacturers will suffice to
    eliminate weak patents preserved through a reverse payment
    to the initial challenger. Cf., e.g., id. at 211-12. We note that
    the initial generic challenger is necessarily the most
    motivated because, unlike all subsequent challengers, it
    stands to benefit from the 180-day exclusivity period of 
    21 U.S.C. § 355
    (j)(5)(B)(iv). Additionally, as the experience of
    at least one court in this Circuit confirms, the high profit
    margins of a monopolist drug manufacturer may enable it to
    pay off a whole series of challengers rather than suffer the
    11
    The Pharmaceutical Research and Manufacturers of
    America points to a more recent study concluding that, in the
    years from 2000 to 2009, generics prevailed in slightly less
    than half of their challenges. RBC Capital Mkts.,
    Pharmaceuticals: Analyzing Litigation Success Rates 4
    (2010), available at http://www. amlawdaily.typepad.
    com/pharmareport.pdf. Even if the industry’s own figures are
    accepted, they show that a substantial fraction of Hatch-
    Waxman patent challenges succeed on the merits. Moreover,
    the study cited by the industry further states that “when you
    take into account patent settlements and cases that were
    dropped, the success rate for generics jumps to 76%,
    substantially in favor of challenging patents.” 
    Id.
    28
    possible loss of its patent through litigation. See King Drug
    Co. of Florence, Inc., 
    702 F. Supp. 2d at 521-22
     (drug
    manufacturer settled infringement suits by four generic firms,
    which agreed to delay market entry “in exchange for
    significant payments . . . for various licensing agreements,
    supply agreements and research and development deals”).
    This practical analysis is supported by a long line of
    Supreme Court cases recognizing that valid patents are a
    limited exception to a general rule of the free exploitation of
    ideas. It follows that the public interest supports judicial
    testing and elimination of weak patents. See Cardinal Chem.
    Co. v. Morton Int’l, Inc., 
    508 U.S. 83
    , 100-01 (1993)
    (explaining the “importance to the public at large of resolving
    questions of patent validity” and noting the danger of
    “grant[ing] monopoly privileges to the holders of invalid
    patents”); Bonito Boats, Inc. v. Thundercraft Boats, Inc., 
    489 U.S. 141
    , 146 (1989) (noting that the patent laws embody “a
    careful balance between the need to promote innovation and
    the recognition that imitation and refinement through
    imitation are both necessary to invention itself and the very
    lifeblood of a competitive economy”); United States v.
    Masonite Corp., 
    316 U.S. 265
    , 277 (1942) (a patent “affords
    no immunity for a monopoly not fairly or plainly within the
    grant”); 
    id. at 280
     (patents are to be “strictly construed”
    because they are “privileges restrictive of a free economy”);
    Pope Mfg. Co. v. Gormully, 
    144 U.S. 224
    , 234 (1892) (“It is
    as important to the public that competition should not be
    repressed by worthless patents, as that the patentee of a really
    valuable invention should be protected in his monopoly.”).
    That reasoning underlies the decision of the Supreme
    Court in Edward Katzinger Co. v Chicago Metallic
    Manufacturing Co., where the Court considered whether a
    patent licensor could be contractually estopped from
    challenging the validity of the patent under a licensing
    agreement that also contained a price fixing term. 
    329 U.S. 394
     (1947). The Court reasoned that if the patent was invalid,
    the price fixing provision would violate federal antitrust law
    and that, as such, the licensor could not be estopped from
    challenging the patent. 
    Id. at 399, 401-02
    . In reaching this
    29
    conclusion the Court emphasized “the broad public interest in
    freeing our competitive economy from the trade restraints
    which might be imposed by price-fixing agreements
    stemming from narrow or invalid patents.” 
    Id.
     at 400 (citing
    Sola Elec. Co. v. Jefferson Elec. Co., 
    317 U.S. 173
    , 177
    (1942)). The Court additionally stated: “It is the public
    interest which is dominant in the patent system and . . . the
    right to challenge [a patent] is not only a private right to the
    individual, but it is founded on public policy which is
    promoted by his making the defence, and contravened by his
    refusal to make it.” Id. at 401 (internal citations and
    quotation marks omitted).
    This logic is persuasive with respect to the situation at
    bar because reverse payments permit the sharing of monopoly
    rents between would-be competitors without any assurance
    that the underlying patent is valid. See also United States v.
    Studiengesellschaft Kohle, m.b.H., 
    670 F.2d 1122
    , 1136 (D.C.
    Cir. 1981) (suggesting an agreement might be anticompetitive
    if it “give[s] potential competitors incentives to remain in
    cartels rather than turning to another product, inventing
    around the patent, or challenging its validity”). It appears that
    these aspects of the Supreme Court’s general patent
    jurisprudence had been overlooked by the Special Master and
    others adopting the scope of the patent test.
    We caution that our decision today is limited to reverse
    payments between patent holders and would be generic
    competitors in the pharmaceutical industry. As the Supreme
    Court has made clear, “antitrust analysis must sensitively
    recognize and reflect the distinctive economic and legal
    setting of the regulated industry to which it applies.” Verizon
    Commc’ns. Inc. v. Law Offices of Curtis V. Trinko, LLP, 
    540 U.S. 398
    , 411-12 (2004); see also IA Phillip E. Areeda &
    Herbert Hovenkamp Antitrust Law, ¶ 240d, 289 (3d ed.
    2006) (“[T]he presence of regulation in some instances limits
    the antitrust role and in some instances simply changes it or
    even enlarges it.”). The Supreme Court’s admonition is
    particularly relevant in an industry, like the pharmaceutical
    industry, that is subject to extensive regulation in which
    Congress has balanced the protection of intellectual property
    30
    and the need for competition. Specifically, in passing the
    Hatch-Waxman Act, Congress drew a careful line between
    patent protection and the need to provide incentives for
    competition in the pharmaceutical industry. See 130 Cong.
    Rec. 24425 (Sept. 6, 1984) (statement of Rep. Waxman
    underscoring the “fundamental balance of the bill”); H.R.
    Rep. No. 98-857, pt. 2, at 30 (1984) (emphasizing that the bill
    achieves “what the Congress has traditionally done in the area
    of intellectual property law[:] balance the need to stimulate
    innovation against the goal of furthering the public interest”),
    reprinted in 1984 U.S.C.C.A.N. 2686, 2715. The line that
    Congress drew between these competing objectives strongly
    supports the application of rule of reason scrutiny of reverse
    payment settlements in the pharmaceutical industry.
    The goal of the Hatch-Waxman Act is to increase the
    availability of low cost generic drugs. H.R. Rep. No. 98-857,
    pt. 1, at 14, reprinted in 1984 U.S.C.C.A.N. 2647, 2647. One
    method Congress employed was to encourage litigated
    challenges by generic manufacturers against the holders of
    weak or narrow patents. See 
    21 U.S.C. § 355
    (j)(5)(B)(iv)
    (establishing 180-day exclusivity period as reward for
    successfully challenging a patent); S. Rep. No. 107-167, at 4
    (2002) (“Under Hatch-Waxman, manufacturers of generic
    drugs are encouraged to challenge weak or invalid patents on
    brand name drugs so consumers can enjoy lower drug
    prices.”). That goal is undermined by application of the
    scope of the patent test which entitles the patent holder to pay
    its potential generic competitors not to compete. As one
    commentator has noted, this approach nominally protects
    intellectual property, not on the strength of a patent holder’s
    legal rights, but on the strength of its wallet. See Hemphill,
    Paying for Delay, supra at 1614 (“In the Hatch-Waxman Act
    . . . the promotion and delay of litigation are central
    preoccupations of the regulatory regime. An open-ended
    permission for innovators to set innovation policy by self-
    help [through reverse payments] is less plausible, as Congress
    has taken explicit steps to fill those gaps.”) As the Second
    Circuit acknowledged in its Tamoxifen decision, the principal
    beneficiaries of such an approach will be name brand
    manufacturers with weak or narrow patents that are unlikely
    31
    to prevail in court. See 466 F.3d at 211. Thus while such a
    rule might be good policy from the perspective of name brand
    and generic pharmaceutical producers, it is bad policy from
    the perspective of the consumer, precisely the constituency
    Congress was seeking to protect.
    In rejecting the scope of the patent test, we are
    cognizant that such a test encourages settlement, an objective
    our decisions generally support. See, e.g., Ehrheart v.
    Verizon Wireless, 
    609 F.3d 590
    , 595 (3d Cir. 2010)
    (“Settlement agreements are to be encouraged because they
    promote the amicable resolution of disputes and lighten the
    increasing load of litigation faced by the federal courts.”).
    However, the judicial preference for settlement, while
    generally laudable, should not displace countervailing public
    policy objectives or, in this case, Congress’s determination –
    which is evident from the structure of the Hatch-Waxman Act
    and the statements in the legislative record – that litigated
    patent challenges are necessary to protect consumers from
    unjustified monopolies by name brand drug manufacturers.
    We also emphasize that nothing in the rule of reason test that
    we adopt here limits the ability of the parties to reach
    settlements based on a negotiated entry date for marketing of
    the generic drug: the only settlements subject to antitrust
    scrutiny are those involving a reverse payment from the name
    brand manufacturer to the generic challenger. Data analyzed
    by the FTC suggest that this will leave the vast majority of
    pharmaceutical patent settlements unaffected. See FTC,
    Bureau of Competition, Agreements Filed with the Federal
    Trade Commission under the Medicare Prescription Drug,
    Improvement, and Modernization Act of 2003: Overview of
    Agreements Filed in FY 2010, 2 (2011) (showing that nearly
    seventy-five percent of Hatch-Waxman Act infringement
    suits that settled in 2010 did so without reverse payments),
    available at http://www.ftc.gov/os/2011/05/1105
    mmagreements.pdf.
    For all of these reasons we reject the scope of the
    patent test. In its place we will direct the District Court to
    apply a quick look rule of reason analysis based on the
    economic realities of the reverse payment settlement rather
    32
    than the labels applied by the settling parties. Specifically,
    the finder of fact must treat any payment from a patent holder
    to a generic patent challenger who agrees to delay entry into
    the market as prima facie evidence of an unreasonable
    restraint of trade, which could be rebutted by showing that the
    payment (1) was for a purpose other than delayed entry or (2)
    offers some pro-competitive benefit.
    In holding that a reverse payment is prima facie
    evidence of an unreasonable restraint of trade, we follow the
    approach suggested by the DC Circuit in Andrx and embrace
    that court’s common sense conclusion that “[a] payment
    flowing from the innovator to the challenging generic firm
    may suggest strongly the anticompetitive intent of the parties
    entering the agreement . . . .” 
    256 F.3d at 809
     (internal
    quotation marks and citation omitted).
    We agree, moreover, with the FTC that there is no
    need to consider the merits of the underlying patent suit
    because “[a]bsent proof of other offsetting consideration, it is
    logical to conclude that the quid pro quo for the payment was
    an agreement by the generic to defer entry beyond the date
    that represents an otherwise reasonable litigation
    compromise.” In re Schering-Plough Corp., Final Order, 136
    F.T.C. at 988. Of course, a patent holder may attempt to
    rebut plaintiff’s prima facie case of an unreasonable restraint
    of trade by arguing that there is in fact no reverse payment
    because any money that changed hands was for something
    other than a delay in market entry. Alternatively, the patent
    holder may attempt to rebut the prima facie case by
    demonstrating that the reverse payment offers a competitive
    benefit that could not have been achieved in the absence of a
    reverse payment. This second possible defense attempts to
    account for the – probably rare – situations where a reverse
    payment increases competition. For example, a modest cash
    payment that enables a cash-starved generic manufacturer to
    avoid bankruptcy and begin marketing a generic drug might
    have an overall effect of increasing the amount of competition
    in the market. For the reasons set forth, we will reverse the
    judgment of the District Court and remand for further
    proceedings in accordance with the foregoing.
    33
    IV.   THE CLASS CERTIFICATION ISSUE
    (Appeal No. 10-4571)
    A. Procedural Background
    The other issue before us on this appeal concerns
    plaintiffs’ effort to certify a class of persons who purchased
    K-Dur directly from Schering between November 20, 1998
    and September 1, 2001 and subsequently purchased a generic
    version of K-Dur. As identified by the parties’ experts, the
    class consists of forty-four wholesalers and retailers. The
    Special Master recommended granting plaintiffs’ motion to
    certify the class. The District Court adopted the Special
    Master’s Report and Recommendation and formally certified
    the class.
    Defendants sought interlocutory review of the District
    Court’s order under Federal Rule of Civil Procedure 23(f).
    While that petition was pending, the District Court ruled on
    the cross motions for summary judgment and entered final
    judgment in defendants’ favor. Plaintiffs filed a notice of
    appeal, and defendants filed a cross appeal, which this court
    dismissed as untimely. See Order, In re K-Dur Antitrust
    Litig., No. 10-2727 (3d Cir. Nov. 24, 2010). However, this
    court accepted defendants’ Rule 23(f) petition, see Order, In
    re K-Dur Antitrust Litig., No. 09-8006 (3d Cir. Nov. 16,
    2010), and we therefore have jurisdiction pursuant to 
    28 U.S.C. § 1292
    (e). 12
    12
    Plaintiffs argue that because defendants’ cross appeal
    was dismissed as untimely defendants’ 23(f) petition should
    have been dismissed also. An appeals court has discretion to
    consider an interlocutory appeal even after the entry of final
    judgment. Cf. In re Coordinated Pretrial Proceedings in
    Petroleum Prods. Antitrust Litig., 
    788 F.2d 1571
    , 1573-74
    (Temp. Emer. Ct. App. 1986). Moreover, in granting
    defendants’ 23(f) petition, this court has already considered
    the issue of the appropriateness of review, and we see no
    reason to reconsider the decision to hear this appeal.
    34
    B. Standard of Review
    This court reviews class certification orders “for abuse
    of discretion, which occurs if the district court’s decision rests
    upon a clearly erroneous finding of fact, an errant conclusion
    of law or an improper application of law to fact.” In re
    Hydrogen Peroxide Antitrust Litig., 
    552 F.3d 305
    , 312 (3d
    Cir. 2008) (internal quotation marks and citation omitted).
    C. Defendants’ Arguments
    In order to certify a class under Rule 23(b)(3), a
    plaintiff must satisfy both the general class action
    prerequisites – numerosity, commonality, typicality, and
    adequacy of representation – and the additional requirements
    of predominance and superiority. Fed. R. Civ. P. 23(a),
    (b)(3). The Special Master, in a report adopted in full by the
    District Court, discussed the class requirements in detail;
    defendants challenge only a few of those findings.
    Defendants assert that (1) plaintiffs cannot use common
    evidence to prove that the class members suffered an actual
    injury from defendants’ conduct because showing actual
    injury means demonstrating lost profits damages, which
    defendants argue necessarily requires individualized
    assessments, (2) even assuming that overcharges are an
    acceptable form of injury, the District Court erred in its
    conclusion that there was common evidence of injury to all
    class members, and (3) the class should not have been
    certified because of inherent conflicts between members.
    Defendants’ first two arguments challenge the District
    Court’s finding with respect to the predominance
    requirement, while the third goes to the adequacy
    requirement. We address these arguments in order.
    1. Predominance Issues
    In order for the predominance requirement to be
    satisfied “[i]ssues common to the class must predominate
    over individual issues.” In re Hydrogen Peroxide, 552 F.3d
    at 311 (internal citations and quotation marks omitted). Class
    certification calls for the district court to conduct a “rigorous
    35
    assessment of the available evidence,” id. at 312, and is only
    appropriate in antitrust cases where plaintiffs can show, by a
    preponderance of the evidence, that proof of the essential
    elements of the cause of action, including antitrust injury, do
    not require individual treatment. Id. at 307, 311.
    It is plaintiffs’ thesis that they will prove that class
    members paid more for K-Dur because of Schering’s antitrust
    violations, and that this constitutes the required antitrust
    impact. The Special Master accepted this based on Third
    Circuit law, stating:
    The Third Circuit has held that “when an
    antitrust violation impacts upon a class of
    persons who do have standing, there is no
    reason in doctrine why proof of impact cannot
    be made on a common basis, so long as the
    common proof adequately demonstrates some
    damage to each individual.”
    App. at 7980 (quoting Bogosian v. Gulf Oil Corp., 
    561 F.2d 434
    , 454 (3d Cir. 1977)). Because all of the class members
    purchased some of the generic versions of K-Dur, plaintiffs
    have satisfactorily explained their theory of impact.
    Plaintiffs proposed to prove antitrust injury through
    common proof consisting largely of the declarations and
    report of their expert, Dr. Leitzinger. Dr. Leitzinger offered
    statistical and economic analyses of the overall brand-name
    and generic drug market and of the specific entry of generic
    potassium chloride in the market to show that, but for the
    challenged reverse payment agreements, “all (or virtually all)
    members of the proposed class” would have purchased at
    least some less expensive generic potassium chloride earlier,
    and therefore suffered an antitrust injury as a result of the
    delay in generic entry. The Special Master considered Dr.
    Leitzinger’s proposed methodology and the criticisms of it
    made by defendants’ expert, Dr. Rubinfeld, in detail. After
    slightly narrowing the class definition to accommodate a
    36
    criticism made by defendants’ expert, 13 the Special Master
    found that plaintiffs had satisfied their burden of showing that
    antitrust impact may be proven by evidence common to all
    class members.
    In December 2008, several months after the Special
    Master’s Report and Recommendation, this court issued its
    decision in In re Hydrogen Peroxide Antitrust Litigation,
    which clarified the standard to be applied when certifying a
    class of plaintiffs in an antitrust action. 
    552 F.3d 305
    . In that
    case, we held that the preponderance requirement demands
    more than a mere threshold showing by a party seeking to
    certify a class and that, in considering a motion for class
    certification, a district court is required to resolve any factual
    or legal disputes necessary to determine whether a plaintiff
    will be able to show antitrust injury for all plaintiffs with
    common evidence.

    .
    a. Whether Lost Profits Are the Relevant Antitrust
    Injury
    Defendants argue first that the predominance
    requirement of Rule 23(b)(3) is not satisfied because, in order
    to prove actual injury from delayed generic entry, plaintiffs
    must produce evidence of lost profits, which necessarily
    requires an individual assessment for each class member.
    Defendants contend specifically that some of the wholesalers
    lost substantial sales volumes after generic entry, and that, for
    such wholesalers, generic entry caused a decrease in profits.
    Defendants’ lost profits argument is unavailing
    because it is simply a version of the so-called “passing-on
    defense” that was rejected by the Supreme Court in Hanover
    Shoe, Inc. v. United Shoe Machinery Corporation. 
    392 U.S. 481
     (1968). In that case, the Supreme Court held that
    demonstrating antitrust injury does not require a showing of
    13
    Specifically, the Special Master excluded from the class
    direct purchasers who did not purchase a generic version of
    K-Dur after generic entry.
    37
    lost profits. 
    Id. at 494
    . Rather, the Supreme Court ruled that
    a plaintiff suffers an antitrust injury where it is overcharged
    for a product, regardless of whether it can show lost profits.
    
    Id. at 492-95
    . In reaching this conclusion, the Court noted
    that requiring plaintiffs to show lost profits was too
    burdensome on both courts and litigants and would undercut
    the effectiveness of private antitrust suits as an enforcement
    mechanism. 
    Id. at 492-94
    ; see also Bogosian, 
    561 F.2d at 456
     (noting that a lost-profits inquiry would be “enormously
    complicated, posing a tremendous burden on the presentation
    of plaintiffs’ case” and that “it is precisely for this reason that
    the Supreme Court eliminated the ‘passing-on defense’ in
    Hanover Shoe”).
    Defendants argue that the Hanover Shoe rule should
    not apply here because that case involved an overcharge for
    an identical product whereas this one involves two different
    products, a name brand drug with a higher price and a lower
    priced generic drug. However, defendants cite no authority
    distinguishing Hanover Shoe on that basis, and their own
    expert conceded that the generic supplement that Schering
    began manufacturing after Upsher entered the market was
    made in the same plant as K-Dur and chemically identical to
    K-Dur. Moreover, in In re Warfarin Sodium Antitrust
    Litigation, this court affirmed class certification where
    plaintiffs sought overcharges – not lost profits – stemming
    from anti-competitive behavior that hindered their access to
    generic pharmaceuticals. 
    391 F.3d 516
    , 532 (3d Cir. 2004).
    In sum, defendants’ contention that plaintiffs are
    required to show lost profits in order to demonstrate antitrust
    injury is without support in law or the facts of this case. As
    such, we reject it.
    b. Whether There Was Common Evidence of Injury to
    All Class Members
    Defendants argue that because of discrepancies in the
    pricing of K-Dur and variations in purchaser behavior,
    plaintiffs cannot prove injury to all class members by
    common evidence, even if lost profits are not required to
    38
    show antitrust injury. They contend further that the District
    Court applied the wrong standard in evaluating plaintiffs’
    evidence that antitrust injury could be proven by common
    evidence.
    In support of their argument that antitrust injury
    requires an individualized assessment for each class member,
    defendants point to two places where purportedly conflicting
    evidence demonstrates the need for individualized assessment
    of antitrust harm. Defendants point out that they did not sell
    K-Dur to all customers at a single list price; rather, the price
    paid varied considerably among class members.
    Additionally, defendants argue that, for certain customers at
    certain times, Schering offered rebates which caused further
    price variation among customers. Defendants contend that
    these pricing variations caused several class members to have
    zero or negative damages under the formula applied by
    plaintiffs’ expert. Finally, defendants point out that not all
    class members purchased generic potassium chloride as soon
    as it became available and argue that, in light of this variation
    in purchase timing, plaintiffs need to make an individualized
    showing that each plaintiff would have purchased a generic
    product earlier if one had been available.
    We do not read Hydrogen Peroxide as precluding a
    class because of variations in purchasing by a very small
    percentage of those who purchased K-Dur. As the Special
    Master recognized, defendants conceded “that 45 of the
    proposed Class members purchased some amount of generic
    K-Dur.” App. at 7984 (emphasis in original). He noted that
    defendants’ arguments “relate to the quantum of damages,
    rather than the fact of injury.” 
    Id.
     Indeed, in Hydrogen
    Peroxide itself, we focused on what was really at issue – that
    for certification plaintiff need not prove antitrust injury
    actually occurred.
    Plaintiffs’ burden at the class certification stage
    is not to prove the element of antitrust impact,
    although in order to prevail on the merits each
    class member must do so. Instead, the task for
    plaintiffs at class certification is to demonstrate
    39
    that the element of antitrust impact is capable of
    proof at trial through evidence that is common
    to the class rather than individual to its
    members.
    
    552 F.3d at 311-12
    . To the extent that there were minor
    variations, they can be handled at trial in the context of
    damages.
    With regard to both the price-variation and purchase-
    timing issues, the Special Master conducted an exceedingly
    thorough review of plaintiffs’ proposal for demonstrating
    antitrust impact through common evidence and determined
    that defendants’ objections were without support. Critically,
    the Special Master recognized his obligation to “probe
    beyond the pleadings” and to conduct a “rigorous analysis” of
    the available evidence. App. at 7960 (internal citations and
    quotation marks omitted).
    Our review confirms that the Special Master applied
    the appropriate standard. In contrast to Hydrogen Peroxide,
    where the court found that there was “no tendency for prices .
    . . to move together,” 
    552 F.3d at 314
     (internal quotation
    marks omitted), plaintiffs in this case presented evidence,
    credited by the Special Master, of significant, industry-wide
    price drops after generic entry. Such evidence of an industry-
    wide price drop after generic entry supports the Special
    Master’s rejection of defendants’ arguments about limited
    price variations and purchase-timing variations between
    plaintiffs.
    First, concerning the price-variation argument, the
    Special Master carefully considered the conflicting opinions
    of plaintiffs’ and defendants’ experts and credited the theories
    of plaintiffs’ expert over that of defendants. The Special
    Master concluded that “Plaintiffs have satisfied their burden
    of adducing sufficient evidence and a plausible theory to
    convince me that impact may be proven by evidence common
    to all class members.” App. at 7988 (internal citations and
    quotation marks omitted). Our review of the record confirms
    that plaintiffs presented a comprehensive and detailed means
    40
    of proving impact through common means, notwithstanding
    some very limited pricing variation, and that the Special
    Master conducted an appropriately searching evaluation of
    this evidence.
    With regard to defendants’ argument about variations
    in the timing of the purchase of generic K-Dur, the Special
    Master explicitly rejected that argument and concluded that
    “[e]vidence that all (or virtually all) class members
    substituted a lower priced generic for some of their K-Dur 20
    purchases gives rise to the inference that they would have
    similarly done in the but-for world.” App. at 7984. This,
    combined with plaintiffs’ theory of damages, means that
    impact could be proven on a class-wide basis via common
    evidence. Here again, the Special Master conducted a
    thorough evaluation of the available evidence and resolved all
    significant disputes between conflicting evidence as required
    under the standard set forth in Hydrogen Peroxide.
    2. Adequacy Issue – Whether the Class
    Faces Inherent Conflicts
    Defendants next contend that the District Court erred
    in certifying a class because the class faces inherent conflicts
    that preclude adequacy of representation. “The inquiry that a
    court should make regarding the adequacy of representation
    requisite of Rule 23(a)(4) is to determine that the putative
    named plaintiff has the ability and the incentive to represent
    the claims of the class vigorously, . . . and that there is no
    conflict between the individual’s claims and those asserted on
    behalf of the class.” In re Cmty. Bank of N. Va., 
    622 F.3d 275
    , 291 (3d Cir. 2010) (quoting Hassine v. Jeffes, 
    846 F.2d 169
    , 179 (3d Cir. 1988)). Only a fundamental conflict will
    defeat adequacy of representation. See, e.g., 
    id. at 303
    (adequacy defeated by “obvious and fundamental intra-class
    conflict of interest”); Ward v. Dixie Nat. Life Ins. Co., 
    595 F.3d 164
    , 180 (4th Cir. 2010).
    Defendants contend that three members of the class, all
    national wholesalers, were net beneficiaries of the absence of
    generic competition in the potassium chloride supplement
    41
    market because once generics came on the market those class
    members saw decreased sales volumes and lower per-pill
    profits. Defendants argue that, because these three class
    members have financial incentives to delay generic entry,
    there is an inherent conflict between them and the rest of the
    class.
    The case law on defendants’ argument reveals a split
    in authority. A large number of district courts, including
    some in this Circuit, have rejected defendants’ argument.
    See, e.g., Teva Pharms USA, Inc. v. Abbott Labs., 
    252 F.R.D. 213
    , 226-27 (D. Del. 2008) (Robinson, J.); Meijer, Inc. v.
    Abbott Labs., 
    251 F.R.D. 431
    , 435 (N.D. Cal. 2008); but see
    Valley Drug Co. v. Geneva Pharms., Inc., 
    350 F.3d 1181
    ,
    1190 (11th Cir. 2003). 14
    We reject the Valley Drug decision for two reasons.
    First, requiring plaintiffs to show that no class member
    benefitted from the challenged conduct in the form of greater
    profits is contrary to the Supreme Court’s decision in
    Hanover Shoe. In Hanover Shoe, the Supreme Court
    permitted antitrust plaintiffs to seek overcharge damages
    rather than lost profits damages precisely because proving
    lost profits was too complicated and burdensome. 
    392 U.S. at 493
    ; Bogosian, 
    561 F.2d at 456
    . The same logic applies
    equally, if not more strongly, in the class certification setting
    because under defendants’ proposed approach, plaintiffs
    would not only have to assess their own lost profits but also
    those of potential class members. Moreover, because
    Hanover Shoe sets the amount of the overcharge as plaintiffs’
    damages, all of the class members have the same financial
    incentive for purposes of the litigation – i.e. proving that they
    were overcharged and recovering damages based on that
    overcharge. See 7A Charles Alan Wright, Arthur R. Miller &
    Mary Kay Kane, Federal Practice and Procedure § 1768 (3d
    ed. 2005) (“[A] potential conflict between the representatives
    and some class members should not preclude the use of the
    class-action device if the parties appear united in interest
    14
    This is a different appeal than Valley Drug, 
    344 F.3d 1294
     (11th Cir. 2003), discussed supra.
    42
    against an outsider at the beginning of the case.”).
    Defendants have not pointed to any plausible scenario in
    which the class members might seek conflicting forms of
    relief. For these reasons, we conclude that defendants’
    conflict argument fails.
    D. Conclusion – Class Certification Issues
    In sum, with respect to the class certification issues,
    we reject defendants’ arguments and will affirm the District
    Court’s determination approving maintenance of the class
    action.
