    November 21, 2016
    LYNCH, Circuit Judge.     This appeal arises from the first
    pharmaceutical-settlement antitrust action tried before a jury
    since the Supreme Court's decision in FTC v. Actavis, Inc., 
    133 S. Ct. 2223
     (2013).       The jury found that although the plaintiffs had
    proved   an    antitrust    violation    in    the   form   of    a    large   and
    unjustified     reverse    payment    from    AstraZeneca   to    Ranbaxy,     the
    plaintiffs had not shown that they had suffered an antitrust injury
    that entitled them to damages.
    Defendant AstraZeneca is a brand-name drug manufacturer
    that owns the patents covering Nexium, a prescription heartburn
    medication that has grossed billions of dollars in annual sales.
    After defendant Ranbaxy notified the Food and Drug Administration
    ("FDA") that it sought to market a generic version of Nexium,
    AstraZeneca     sued   Ranbaxy   for    patent    infringement.          The   two
    companies reached a settlement agreement, under which Ranbaxy
    agreed to delay the launch of its generic until a certain date in
    return   for     various   promises     from    AstraZeneca.          AstraZeneca
    similarly sued and subsequently settled two patent infringement
    suits with generic manufacturers Teva and Dr. Reddy's, who were
    (but no longer remain) defendants in this case.                  The plaintiffs
    -- various pharmaceutical retail outlets and certified classes of
    direct purchasers and end payors -- brought suit, arguing that the
    terms of these settlement agreements violated federal antitrust
    laws and state analogues.
    - 3 -
    After summary judgment proceedings that winnowed down
    the number of causal mechanisms through which the plaintiffs could
    attempt to prove antitrust violation and injury, the case proceeded
    to a jury, which found as we have described.                  Following the
    verdict, the district court denied the plaintiffs' motions for a
    permanent injunction and for a new trial.
    The   plaintiffs    appeal,       raising    four   categories   of
    claims.   First,   they   challenge     various       evidentiary   rulings.
    Second, they argue that the district court erroneously granted
    judgment as a matter of law in the defendants' favor on the issue
    of overarching conspiracy.      Third, they argue that the special
    verdict form and jury instructions contained reversible error.
    The final argument, which lies at the heart of this appeal, is
    that the district court, at summary judgment, impermissibly cut
    down the number of causal mechanisms through which the plaintiffs
    could make their case to the jury. See In re Nexium (Esomeprazole)
    Antitrust Litig. ("In re Nexium [Summary Judgment]"), 
    42 F. Supp. 3d 231
     (D. Mass. 2014).      This error at summary judgment pervaded
    the entire trial, the plaintiffs argue, and constitutes grounds to
    vacate the jury verdict and award a new trial.
    We find no reversible error in the district court's
    evidentiary rulings, the formulation of the special verdict form
    and jury instructions, or its judgment as a matter of law on
    overarching   conspiracy.      In    fact,    many     of   the   plaintiffs'
    - 4 -
    objections have been forfeited or mooted by the jury's findings.
    We further hold that the jury verdict, finding an antitrust
    violation but not an antitrust injury, coupled with developments
    at trial on the issue of patent invalidity, renders harmless any
    error   that    may   have     occurred    during    the    summary      judgment
    proceedings.     Accordingly, we need not, and indeed should not,
    review the summary judgment order for error.               We affirm.
    I.    REGULATORY FRAMEWORK
    An overview of the intricate pharmaceutical regulatory
    framework is necessary to understand the issues presented.                     A
    manufacturer that seeks to market a new brand-name drug must file
    a New Drug Application ("NDA") with the FDA and "undergo a long,
    comprehensive, and costly testing process."              Actavis, 
    133 S. Ct. at 2228
    .     Generic-drug manufacturers formerly underwent similarly
    rigorous     processes   to    obtain   FDA   approval     to   market   generic
    versions of the brand-name drug.          In order to accelerate the entry
    of generic competitors into the market and decrease healthcare
    costs, Congress enacted the Drug Price Competition and Patent Term
    Restoration Act of 1984 ("Hatch-Waxman Act"), Pub. L. No. 98-417,
    
    98 Stat. 1585
    .      The   Hatch-Waxman    Act   has     three    regulatory
    components that are relevant here.
    First, the Act permits generic manufacturers to file the
    notably less costly Abbreviated New Drug Application ("ANDA"),
    "specifying that the generic has the 'same active ingredients as,'
    - 5 -
    and is 'biologically equivalent' to, the already-approved brand-
    name drug."     Actavis, 
    133 S. Ct. at 2228
     (quoting Caraco Pharm.
    Labs., Ltd. v. Novo Nordisk A/S, 
    132 S. Ct. 1670
    , 1676 (2012)).
    "[B]y allowing the generic to piggy-back on the pioneer's approval
    efforts, [the Hatch-Waxman Act] 'speed[s] the introduction of low-
    cost   generic       drugs    to    market,'     thereby   furthering     drug
    competition."    
    Id.
     (third alteration in original) (quoting Caraco,
    
    132 S. Ct. at 1676
    ).
    Second, the Act requires brand-name manufacturers to
    list the numbers and expiration dates of all relevant patents in
    their NDAs, which are then published in the FDA's "Orange Book,"
    an annual publication of all approved drugs and the reported
    patents or statutory exclusivities that cover those drugs.                 In
    turn, generic manufacturers filing ANDAs must "'assure the FDA'
    that the generic 'will not infringe' the brand-name's patents,"
    and may provide this assurance in one of four ways.            
    Id.
     (quoting
    Caraco,   
    132 S. Ct. at 1676
    ).   The   generic   manufacturer   may
    (1) certify that the brand-name manufacturer has failed to list
    any relevant patents; (2) certify that any relevant patents have
    expired; (3) request the FDA's approval to market its generic upon
    the expiration of any still active patents covering the brand name;
    or (4) certify that "any listed, relevant patent 'is invalid or
    will not be infringed by the manufacture, use, or sale' of the
    - 6 -
    drug   described       in     the    [ANDA]."         
    Id.
       (quoting    
    21 U.S.C. § 355
    (j)(2)(A)(vii)(IV)).
    This     last        route,     known    as     a   "paragraph    IV
    certification," usually triggers an immediate patent infringement
    suit from the brand-name manufacturer.                 If that suit is brought
    within 45 days of the paragraph IV certification, the FDA must
    withhold approval of the generic ANDA, usually for a 30-month
    period, during the course of litigation on patent validity or
    infringement.        
    Id.
        If the court decides the patent matter within
    30 months, the FDA follows the court's determination.                   But if the
    court does not, the FDA may approve an ANDA before a court rules
    on   patent    validity       or    infringement.       
    Id.
       (citing   
    21 U.S.C. § 355
    (j)(5)(B)(iii)).              This pre-ruling approval, in turn, allows
    the generic manufacturer to launch its product "at risk" -- that
    is, "with the risk of losing the infringement case against it
    hanging over its head. Losing an infringement case after launching
    at risk can result in significant liability for the generic
    manufacturer, as damages typically are calibrated by the amount of
    its at-risk sales."         In re Nexium [Summary Judgment], 42 F. Supp.
    3d at 245.
    The final relevant component of the Hatch-Waxman Act is
    that it rewards the first generic manufacturer to file an ANDA
    with a paragraph IV certification by granting that first filer a
    180-day period of exclusivity.                Actavis, 
    133 S. Ct. at
    2228–29.
    - 7 -
    During that 180-day window, the FDA cannot approve ANDAs from
    competing manufacturers for the same generic, leaving only the
    first filer with the ability to market its generic.                      Accordingly,
    this period of exclusivity can be "worth several hundred million
    dollars."        
    Id. at 2229
     (quoting Hemphill, Paying for Delay:
    Pharmaceutical Patent Settlement as a Regulatory Design Problem,
    
    81 N.Y.U. L. Rev. 1553
    , 1579 (2006)).                In fact, the "vast majority
    of potential profits for a generic drug manufacturer materialize
    during the 180-day exclusivity period."                     
    Id.
         From the market
    perspective, however, the first filer may create a bottleneck, as
    all other generic manufacturers must wait for the exclusivity
    period to end before launching their own generics.
    Significantly, this lucrative 180-day exclusivity period
    is    not     absolute.          Under      the   Medicare       Prescription       Drug,
    Improvement, and Modernization Act of 2003, Pub. L. No. 108-173,
    
    117 Stat. 2066
    , a first filer may forfeit its exclusivity period
    if    it    fails    to   come    to   market     within    75    days   of    a   final,
    nonappealable court judgment that the first filer's product does
    not        infringe       the     brand-name's       patents.             
    21 U.S.C. §§ 355
    (j)(5)(D)(i)(I)(bb), (D)(ii).                  Alternatively, first-filer
    exclusivity         can   be    forfeited    if   another    generic     manufacturer
    successfully challenges the brand-name patents at issue and if the
    first filer fails to market its generic within 75 days of a final,
    - 8 -
    nonappealable judgment in that other manufacturer's suit.      Id.;
    see also In re Nexium [Summary Judgment], 42 F. Supp. 3d at 246.
    In 2013, the Supreme Court held that reverse payment
    settlements in paragraph IV litigation "can sometimes violate the
    antitrust laws."   Actavis, 
    133 S. Ct. at 2227
    .   A reverse payment
    refers to an arrangement in which the brand-name manufacturer and
    patent holder compensates the generic manufacturer and alleged
    patent infringer to settle the paragraph IV litigation and delay
    the generic's market entry.     
    Id. at 2229
    .      When a brand-name
    manufacturer pays to delay the first filer's generic launch, that
    reverse payment postpones not only the first filer's product but
    also those of all other generic manufacturers, who must wait out
    the 180-day exclusivity period before going to market.   Given that
    "a reverse payment, where large and unjustified, can bring with it
    th[is] risk of significant anticompetitive effects," the Supreme
    Court held that the potential anticompetitive effects of a reverse
    payment are subject to the antitrust "rule of reason" test.     
    Id. at 2237
    .
    Earlier this year, in In re Loestrin 24 Fe Antitrust
    Litigation, 
    814 F.3d 538
     (1st Cir. 2016), this circuit ruled that
    improper reverse payments may take the form of "non-monetary"
    advantages.   Id. at 549.     The language and logic of Actavis
    dictated that outcome.   See id. ("[T]he Supreme Court recognized
    that a disguised above-market deal, in which a brand manufacturer
    - 9 -
    effectively overpays a generic manufacturer for services rendered,
    may qualify as a reverse payment subject to antitrust scrutiny and
    militates against limiting the Supreme Court's decision to pure
    cash   payments.").        Under    this    functional   approach,     "no-AG"
    provisions -- in which the brand-name manufacturer agrees not to
    market an "authorized generic" version of the drug for a certain
    period of time -- and other settlement provisions in which some
    advantage is transferred from the patent holder to the alleged
    infringer may constitute a reverse payment subject to antitrust
    scrutiny.
    II.    FACTS
    Nexium    is    a   proton-pump       inhibitor    whose    active
    ingredient     is    esomeprazole        magnesium.      The   FDA     approved
    AstraZeneca's NDA to market Nexium in 2001. Between 2008 and 2014,
    Nexium grossed at least $3 billion annually in U.S. sales and
    joined the ranks of "blockbuster" drugs -- those that generate
    annual sales of at least $1 billion.              In 2001, AstraZeneca held
    fourteen active patents covering Nexium.              As relevant here, two
    medical patents expired on May 27, 2014, two other patents expired
    in February 2015 and July 2015, and two more are set to expire in
    May 2018.
    In August 2005, Ranbaxy first filed an ANDA with a
    paragraph IV certification in order to market a generic version of
    Nexium.     The filing stated that Ranbaxy's launch would await the
    - 10 -
    2007 expiration of some of AstraZeneca's Nexium patents, but
    certified that other patents were either not infringed or invalid.
    As to patent invalidity, Ranbaxy contended that there was "nothing
    new" about Nexium, as the active compound in Nexium was effectively
    "one-half" of the compound in Prilosec, another blockbuster drug
    for stomach-acid treatment that AstraZeneca had marketed prior to
    Nexium.
    AstraZeneca promptly brought suit, alleging that Ranbaxy
    had violated six of its patents: two that would expire on May 27,
    2014, two that would expire in 2015, and two that would expire in
    May 2018.      The suit stayed FDA approval of Ranbaxy's ANDA until
    April 2008.      Meanwhile, Teva filed its ANDA for generic Nexium in
    November 2005, and Dr. Reddy's filed in December 2007. AstraZeneca
    sued   Teva     and   Dr.   Reddy's    as   well,    and    all   three   patent
    infringement suits were consolidated in the U.S. District Court
    for the District of New Jersey.
    A.   Settlement Agreements
    Ranbaxy was the first defendant to settle after reaching
    an agreement with AstraZeneca in April 2008.               Under the settlement
    agreement, Ranbaxy received a license to all relevant Nexium
    patents starting on May 27, 2014.              The settlement also contained
    a no-AG clause, under which AstraZeneca agreed not to market an
    authorized generic version of Nexium during Ranbaxy's 180-day
    period of exclusivity.         The clause thus ensured that Ranbaxy's
    - 11 -
    generic would be the only one on the market if it could launch in
    time to avoid triggering the statutory forfeiture provisions.
    AstraZeneca could still continue to market its brand-name drug
    during that period.         In return, Ranbaxy stipulated to patent
    validity    and   infringement      and    consented    to    the   entry    of   an
    injunction against the sale of its generic before the license took
    effect on May 27, 2014.
    AstraZeneca    and    Ranbaxy     also    executed     three     other
    agreements,    under    which     Ranbaxy   would     serve    as   AstraZeneca's
    subcontractor     and   manufacture        certain    quantities     of     branded
    Nexium, and would also serve as AstraZeneca's distributor for
    authorized    generic    versions     of    two   other      AstraZeneca    drugs,
    Prilosec and Plendil.           For the distribution agreement, Ranbaxy
    would receive 20% of AstraZeneca's profits.
    After litigating for a few more years, Teva settled with
    AstraZeneca in January 2010. Like Ranbaxy, Teva received a license
    to the Nexium patents starting on May 27, 2014 and also consented
    to an injunction barring the sale of its generic before that
    license took effect.       Simultaneously, AstraZeneca and Teva agreed
    to settle another pending patent infringement lawsuit regarding
    Prilosec.    In that multiyear litigation, AstraZeneca had succeeded
    in establishing Teva's liability, but Teva had been contesting the
    damages amount based on its past infringing sales.                     Teva paid
    AstraZeneca $9 million to resolve that suit.
    - 12 -
    Dr. Reddy's settled with AstraZeneca in January 2011.
    Like Ranbaxy and Teva, Dr. Reddy's received a license for the
    Nexium patents starting on May 27, 2014 and also consented to an
    injunction    barring      sales   before    that   date.     Simultaneously,
    AstraZeneca     and   Dr.    Reddy's   settled      another   pending    patent
    infringement lawsuit in which AstraZeneca agreed to drop its appeal
    of the entry of summary judgment in Dr. Reddy's favor.
    The   three    settlement      agreements   contained      parallel
    contingent launch provisions under which each generic manufacturer
    agreed to delay launching its generic in the United States until
    (1) May 27, 2014; (2) a hypothetical date prior to May 27, 2014 on
    which any third party launched generic Nexium pursuant to a final,
    nonappealable court order that AstraZeneca's Nexium patents were
    invalid, unenforceable, or not infringed by the generic; or (3) a
    hypothetical date prior to May 27, 2014 on which AstraZeneca
    authorized any third party to manufacture a generic Nexium.                In re
    Nexium [Summary Judgment], 42 F. Supp. 3d at 249 (citing ¶ 5.2 in
    the three settlement agreements).
    B.   Ranbaxy's Regulatory Troubles
    Throughout Ranbaxy's paragraph IV litigation challenging
    AstraZeneca's Nexium patents, Ranbaxy faced serious issues with
    the FDA.     Specifically, Ranbaxy had filed its ANDA for generic
    Nexium out of its manufacturing facility in Paonta Sahib, India,
    which meant that any FDA approval to launch generic Nexium would
    - 13 -
    extend only to that facility.              In February 2009, after issuing
    several warnings about quality control problems with the India
    facility, the FDA ultimately invoked its Application Integrity
    Policy ("AIP") against Paonta Sahib.                   The AIP "halted FDA's
    substantive review and approval of all pending ANDAs, including
    amendments and post-approval supplements that relied on supporting
    data from the Paonta Sahib site -- including the generic Nexium
    ANDA."     Id. at 266.     The agency then rejected Ranbaxy's proposed
    Corrective Action Operating Plan and further turned down Ranbaxy's
    request that it grant a public health exception to the AIP and
    continue    the    approval      process   for   the    generic   Nexium    ANDA.
    Meanwhile, the FDA granted a public health exception for generic
    Lipitor, another Ranbaxy product manufactured out of the Paonta
    Sahib facility.
    In 2010, Ranbaxy and the FDA began negotiating a Consent
    Decree, which they finalized on January 25, 2012. Under its terms,
    Ranbaxy could meet "several onerous and time-consuming milestones"
    to obtain potential FDA approval for generic Nexium or to obtain
    a site-transfer amendment to change the manufacturing site for the
    drug.     The Consent Decree also contained a "key relinquishment
    date" of September 30, 2014.           Id. at 274.       If Ranbaxy could not
    meet the requisite milestones before that date, it would forfeit
    its 180-day exclusivity period.            Id.   Ranbaxy took over two and a
    half     years    to   prepare    a   site-transfer      amendment,   and     the
    - 14 -
    manufacturer failed to receive final FDA approval for its generic
    Nexium ANDA prior to May 27, 2014.
    On November 4, 2014, the FDA rescinded its tentative
    approval of Ranbaxy's generic Nexium ANDA, and Ranbaxy promptly
    sued the FDA in the U.S. District Court for the District of
    Columbia.   See Ranbaxy Labs, Ltd. v. Burwell, 
    82 F. Supp. 3d 159
    ,
    163 (D.D.C. 2015). Subsequently, in January 2015, the FDA notified
    Ranbaxy that it had forfeited its first-filer exclusivity period
    by failing to obtain approval for its generic within 30 months of
    submitting its ANDA.   The FDA simultaneously approved Teva's ANDA
    for generic Nexium, which launched on February 17, 2015.
    C.   Dispute over Teva's Readiness to Launch Generic Nexium
    The plaintiffs' evidence at summary judgment and at
    trial showed that Teva was closer than Ranbaxy to obtaining FDA
    approval and launching generic Nexium before May 27, 2014.      An
    internal Teva email from February 2007 approximated Teva's "Launch
    Readiness date" as July 2008.     And by 2009, Teva had passed FDA
    review in two out of the three categories necessary for tentative
    approval of its generic Nexium.
    The parties vehemently disagreed at summary judgment on
    whether the third remaining category for FDA approval was "a
    significant hurdle or a minor one," an issue material to determine
    whether Teva was indeed close to FDA approval.        In re Nexium

    evidence from both sides on this issue.
    III.     PROCEDURAL HISTORY
    A.   Pretrial Proceedings
    Plaintiffs commenced six different actions in three
    different federal district courts, alleging that AstraZeneca made
    improper reverse payments to Ranbaxy, Teva, and Dr. Reddy's in
    order to delay the market entry of generic Nexium.             On December 7,
    2012,     the   U.S.   Judicial     Panel     on    Multidistrict    Litigation
    consolidated and assigned the six pending actions to the U.S.
    District Court for the District of Massachusetts.               See 
    28 U.S.C. § 1407
    .    This appeal arises from that consolidated case.
    On appeal, plaintiffs are a class of wholesale drug
    distributors (the "Direct Purchasers"); a class of individual
    consumers, third-party payors, union plan sponsors, and certain
    insurance       companies    (the     "End         Payors");   and     numerous
    pharmaceutical retail outlets.1         In January 2015, a panel of this
    circuit affirmed the certification of the End Payors damages class
    over a dissent.        See In re Nexium Antitrust Litig., 
    777 F.3d 9
    (1st Cir. 2015).       The original defendants in this litigation were
    1   The pharmaceutical retail outlets are CVS, Inc.; Eckerd
    Corporation; Giant Eagle, Inc.; HEB Grocery Co. LP; JCG (PJC) USA,
    LLC; the Kroger Company; Maxi Drug, Inc. d/b/a Brooks Pharmacy;
    Rite Aid Corporation; Rite Aid Headquarters Corporation; Safeway
    Incorporated; Supervalu, Inc.; and Walgreen Co.
    - 16 -
    AstraZeneca, Ranbaxy, Teva, and Dr. Reddy's.          Teva and Dr. Reddy's
    have settled, leaving only AstraZeneca and Ranbaxy as defendants
    on appeal.
    Consistent with In re Loestrin 24 Fe, the plaintiffs'
    complaints identified aspects of AstraZeneca's settlements with
    each of the three generic manufacturers that allegedly were reverse
    payments in violation of the antitrust laws.              In the Ranbaxy
    settlement, the plaintiffs pointed to the no-AG clause, as well as
    the side manufacturing and distribution agreements.            In the Teva
    settlement, the plaintiffs argued that Teva's payment of only $9
    million to settle the Prilosec lawsuit, rather than the higher
    amount    that   Teva   actually   owed    AstraZeneca,   constituted   the
    reverse payment.        In the Dr. Reddy's settlement, the plaintiffs
    cited AstraZeneca's agreement to drop its appeal challenging Dr.
    Reddy's    summary   judgment   win   in    another   patent   infringement
    lawsuit.
    In December 2013, the defendants collectively filed
    eleven motions for summary judgment. Following the court's initial
    rulings from the bench, both parties filed various motions for
    reconsideration.        In a September 4, 2014 opinion, the district
    court memorialized its rationale as to each summary judgment motion
    that it decided.     See In re Nexium [Summary Judgment], 
    42 F. Supp. 3d 231
    .    This opinion grouped the motions into five categories:
    - 17 -
    First, the district court denied the defendants' motions
    for partial summary judgment on the existence of an overarching
    antitrust    conspiracy,      among     all   four    original    defendants,   to
    restrain trade in the market for generic Nexium.                   
    Id.
     at 248–60.
    At the pretrial stage, the court found that the plaintiffs had
    "met   their   burden    of     establishing      a   reasonable    inference   of
    overarching conspiracy," 
    id. at 249
    , as the evidence demonstrated
    that each generic "manufacturer's calculus [on its entry date into
    the generic Nexium market] changed . . . when it received assurance
    that it would only have to restrict its business if its competitors
    did the same," 
    id. at 258
    .            The denial of summary judgment to the
    defendants imposed no restrictions on the plaintiffs' ability to
    produce evidence at trial.              Following the plaintiffs' case in
    chief, the district court granted judgment as a matter of law in
    the defendants' favor on this overarching conspiracy claim.
    Second,    although        the    district    court     denied     the
    defendants' motion for summary judgment as to the existence of an
    improper reverse payment from AstraZeneca to Ranbaxy, the court
    granted the motion as to the argument that such a reverse payment
    caused the plaintiffs' injury.            
    Id. at 260
    .     The court elaborated
    that   the   no-AG     clause    in    the    AstraZeneca–Ranbaxy      settlement
    agreement "may be considered part of an illegal reverse payment,"
    
    id. at 265
    , while the lucrative "side" agreements granting Ranbaxy
    supply   and    distribution          contracts   likewise       "raise[]   enough
    - 18 -
    suspicions to support a reasonable inference [of] improper reverse
    payments to induce Ranbaxy to delay its generic launch," 
    id. at 264
    .
    Nonetheless, in light of the quality control issues that
    Ranbaxy's Paonta Sahib facility had experienced, the court found
    that the plaintiffs did not show how Ranbaxy could still have
    obtained final FDA approval and launched its generic before May
    27, 2014.        
    Id. at 270-75
    .              The court was skeptical of the
    plaintiffs'         analogy     to     generic         Lipitor,     which     had   been
    manufactured out of Paonta Sahib and had faced similar regulatory
    issues    but    had   nonetheless          launched      after    Ranbaxy    reached   a
    compromise with the FDA.             
    Id. at 273-74
    .
    "The net effect of these rulings [wa]s that the Ranbaxy
    Settlement      [could]       not    [be]    a    basis    for     imposing   antitrust
    liability."         
    Id. at 279
    .         However, later at trial, the court
    acknowledged its error as to this ruling and reversed course.
    Third, the court denied the defendants' motions for
    summary judgment based on the Teva settlement.                        The court found
    that the plaintiffs' evidence -- that Teva's $9 million payment to
    AstraZeneca to settle the Prilosec lawsuit was so low a sum that
    it "constituted a significant forgiveness of debt" by AstraZeneca
    to delay the launch of Teva's generic -- was sufficient to proceed
    to trial.       
    Id. at 286
    .         The court next found that the plaintiffs
    had    also   met    their     burden   as       to,   what   it    called,   antitrust
    - 19 -
    causation because they showed (1) that Teva was close to obtaining
    tentative FDA approval but slowed down its efforts toward that
    goal after settling with AstraZeneca, and (2) that Teva could have
    entered the market before May 2014, notwithstanding Ranbaxy's
    first-filer exclusivity period, by partnering with Ranbaxy on a
    joint launch.   
    Id.
     at 288–89.2    In sum, the plaintiffs could pursue
    the Teva settlement as a basis for antitrust liability at trial.
    Fourth,   the   district   court   granted   the   defendants'
    motion for summary judgment based on the Dr. Reddy's settlement,
    finding that the plaintiffs had proffered insufficient evidence
    both on the existence of an improper reverse payment and on
    "antitrust causation."     
    Id.
     at 291–95.
    Finally, the district court denied three miscellaneous
    motions for summary judgment that AstraZeneca had filed: (1) a
    motion   against   the   Direct   Purchaser   and   Individual   Retailer
    plaintiffs for lack of actual injury and seeking exclusion of
    testimony from two experts; (2) a motion barring assigned claims;
    and (3) a motion on the basis of the statute of limitations.         
    Id.
    at 295–300.
    2     The court rejected as too speculative another causal
    mechanism -- namely, that Teva could have won its paragraph IV
    suit   and   obtained  a  final,   nonappealable  judgment   that
    AstraZeneca's Nexium patents were invalid or not infringed. That
    theoretical victory could, in turn, have triggered the regulatory
    75-day window within which Ranbaxy had to launch its generic or
    forfeit its first-filer exclusivity. 
    Id.
     at 289–90.
    - 20 -
    In sum, after the summary judgment proceedings, the
    plaintiffs    were      allowed         to    present        evidence     on    AstraZeneca's
    improper reverse payment to Teva and any antitrust liability
    flowing   from    that        payment,        as    well      as    the   existence     of   an
    overarching antitrust conspiracy among AstraZeneca, Ranbaxy, Teva,
    and Dr. Reddy's.          That evidence would include testimony from the
    plaintiffs' expert, Dr. Thomas McGuire. The court further directed
    the plaintiffs to present all evidence supporting an antitrust
    violation    arising          out   of       the    Teva     settlement        first,   before
    presenting any other evidence.
    After summary judgment, at a January 21, 2014 pretrial
    motion hearing, the district court granted the defendants' motion
    in limine to exclude testimony from Shashank Upadhye, a former in-
    house   lawyer     at     a     nondefendant            generic      manufacturer.           The
    plaintiffs sought Upadhye's testimony to "augment Dr. McGuire's
    economic testimony with a real world business perspective on
    settlement negotiations for drug patent lawsuits."                                   The court
    reasoned that Upadhye, along with another proposed expert witness
    (John Thomas), could not testify because they were "lawyers, not
    economists,      and      .    .    .    they      d[id]      not    have      the   requisite
    qualifications       to       testify."            At   an    October     15,    2014   charge
    conference, the court reminded both parties that its decisions
    regarding motions in limine were "not rulings" and that the parties
    - 21 -
    "must make [their] objections known during the course of the
    trial."
    Dr. Reddy's settled and dropped out of the lawsuit
    shortly before trial.
    B.   Trial
    A six-week trial commenced on October 20, 2014.               The
    trial transcript, exhibits, and filings comprise thousands of
    pages in the record.       We summarize only the aspects of trial that
    are relevant to the arguments on appeal.
    1.   Plaintiffs' Statement on Patent Invalidity               and
    Evidence Introduced During Their Case in Chief
    At   a   conference   on   the   second   day   of   trial,   the
    plaintiffs described their case in chief to the district court:
    [In order to show that Teva could have gotten
    to market before May 27, 2014, the district court
    said that the plaintiffs] would need to prove that
    Teva would have won its litigation [against
    AstraZeneca].   And then . . . [the court] also
    indicated though that we could also perhaps prove
    that Teva would have done a deal with Ranbaxy in
    order to have the 180 days lifted.
    . . . We plan to do the latter, primarily in
    our case in chief . . . . We don't plan on proving
    a patent case inside of an antitrust case [by
    pursuing the former]. . . . [W]e do not plan to be
    proving that Teva would have won the litigation.
    This choice by the plaintiffs was not mandated by the district
    court's ruling.       At trial, consistent with the district court's
    order, the plaintiffs first presented evidence on the existence of
    a reverse payment from AstraZeneca to Teva.
    - 22 -
    Dr. McGuire, an economist and one of the plaintiffs' key
    expert witnesses, testified twice during the plaintiffs' case in
    chief.   McGuire first testified to "the enormous financial stakes
    that turned on the entry date of a lower cost generic into a market
    hitherto dominated by a patented, more expensive brand name drug."
    In re Nexium (Esomeprazole) Antitrust Litig. ("In re Nexium [Post-
    Trial Opinion]"), 
    309 F.R.D. 107
    , 119 (D. Mass. 2015).   He further
    "detailed how the benefits AstraZeneca conferred on Teva through
    their mutual settlement exceeded the litigation costs the parties
    thereby avoided."   
    Id.
    During McGuire's second testimony, despite the summary
    judgment order precluding the plaintiffs from introducing evidence
    of a reverse payment to Ranbaxy, the court allowed McGuire to
    testify "for context" on the "far greater reverse payment made by
    AstraZeneca to Ranbaxy to induce it to forego its challenge to
    AstraZeneca's Nexium patents."     
    Id.
       The district court also
    allowed McGuire to testify about Ranbaxy's economic incentives to
    include a contingent launch provision in its settlement agreement
    with AstraZeneca.   Specifically, McGuire noted that the provision
    made it "less likely" that subsequent ANDA filers would pursue
    generic entry.   He further stated that the clause "had the effect
    of reducing the likelihood that Teva would challenge and break the
    bottleneck, which means for Ranbaxy[,] it became more likely that
    - 23 -
    [it was] able to use [its] 180-day exclusivity period and make the
    profits associated with that."
    At one point during McGuire's second testimony, the
    court   forbade   him   from   quantifying   Ranbaxy's   incentive   to
    participate in the overarching conspiracy as "about $700 million
    in [Ranbaxy's] pocket that [it] otherwise wouldn't have." It ruled
    as such because the existence of contingent launch provisions, and
    not that theory, was what kept the plaintiffs' "case against
    Ranbaxy alive."     The court nonetheless allowed McGuire to testify
    that AstraZeneca netted "hundreds of millions of dollars" by
    settling with Ranbaxy to "strengthen the 180-day [first-filer]
    barrier."
    Plaintiffs were permitted to introduce expert testimony
    on the but-for entry dates.     For three days, starting on November
    18 and after the district court articulated its "misconception,"
    the plaintiffs presented the testimony of Dr. Cheryl Blume, their
    "lead witness on the issue of the crucial 'but for entry date.'"
    Id. at 120.   Looking back at trial, the district court noted that
    "Blume did not fare very well, especially under the searching
    cross-examination by Teva's counsel.     The Court was left with the
    distinct impression that much of her testimony was a priori
    rationalization."    Id.
    - 24 -
    2.   The District Court's Mid-Trial Shift, Defendants'
    Mistrial Motion, and the Exclusion of McGuire's Event
    Study and Other Testimony
    On November 18, 2014, the seventeenth day of the trial,
    the   court    admitted    that    it   had    had   a   "fairly    fundamental
    misconception" of the plaintiffs' theory of the case.                    The court
    then adjusted its thinking about the relevance of the AstraZeneca–
    Ranbaxy settlement by noting that "[t]he large and unjustified
    payment   to    Ranbaxy,   which   keeps      Ranbaxy,   given     its    blocking
    position [as first filer], off the market until May 27th, 2014,
    has an effect on all the later ANDA filers, such that if it were
    to be proved that but for that agreement, . . . Teva could have
    partnered with Ranbaxy and come to market prior to that date."
    In light of this shift, the district court announced
    that it would alter the jury verdict form and allow the plaintiffs
    to recall McGuire to testify for a third time.                The court also
    emphasized that its shift in thinking did "not injure[]" the
    plaintiffs because "they seem to have in the record enough evidence
    of a large and unjustified payment to Ranbaxy and based upon their
    expert's testimony it can be argued that it was anticompetitive."
    In response to the district court's stated reversal of
    its position, the defendants filed two motions, to both of which
    the plaintiffs objected.          The first motion was for a mistrial.
    The second was to exclude McGuire's additional proffered testimony
    -- an "Event Study" that postulated an earlier entry date had there
    - 25 -
    not been a reverse payment in the AstraZeneca-Ranbaxy settlement
    -- under Daubert v. Merrell Dow Pharmaceuticals, Inc., 
    509 U.S. 579
     (1993).     The district court first excluded McGuire's Event
    Study testimony under Daubert.          That Study purported to "use
    econometric analysis of the stock market's reaction to the actual
    settlement reached by AstraZeneca and Ranbaxy to estimate an
    objective entry date without [a reverse] payment." While the court
    acknowledged McGuire's expertise and stated that the Event Study's
    methodology was "perhaps reliable," the Study did not meet Daubert
    requirements because there was "no fit" "between the event study
    and this culmination of the case."       The court recognized that the
    plaintiffs might nonetheless want to call McGuire a third time to
    testify to "other things" besides the Event Study.            It ruled,
    however, that it still would not allow him to testify to those
    "additional matters" because to do so would be "simply unfair."
    Given that the court had said on November 18 that it
    would   allow   the   plaintiffs   to     recall   McGuire,   the    court
    acknowledged that its "no more McGuire" ruling could "change the
    plaintiffs' position on mistrial."       It directed the plaintiffs to
    make "tactical decisions" on whether to reassess their initial
    opposition to the defendants' mistrial motion.
    The plaintiffs continued to oppose a mistrial.             They
    pointed out that despite the summary judgment ruling precluding
    evidence   of   AstraZeneca's   reverse    payment   to   Ranbaxy,   such
    - 26 -
    evidence had nonetheless been presented to the jury under another
    theory.   Indeed, the plaintiffs had introduced evidence on that
    payment because it was relevant and admissible under the claim of
    overarching conspiracy.3   Plaintiffs also argued that the "chopped
    up" way in which McGuire's earlier testimony was presented to the
    jury and the court's exclusion of McGuire's Event Study went "a
    long way to curing whatever prejudice . . . these defendants may
    have incurred."
    Immediately following these statements, the court denied
    the motion for mistrial.
    3. Judgment as a Matter of Law on Conspiracy and Patent
    Invalidity
    At the close of the plaintiffs' case, the defendants
    moved for judgment as a matter of law on the overarching conspiracy
    claim, as well as on the question of antitrust causation.       The
    court granted the motion on the conspiracy claim, noting that
    3    The vigor with which the plaintiffs acknowledged the
    admission of evidence on the Ranbaxy reverse payment is worth
    noting:
    From the very beginning of this case the payment to
    Ranbaxy has been in clearly as at least an overt
    act in furtherance of the conspiracy. . . . But
    for [the defendants] to come here now and say, Oh,
    this was never in the case, that simply from our
    perspective is not true. It was unclear exactly
    how much and what role that payment was going to
    make, but it was clear it was in this as an overt
    act . . . . And we made our tactical choices and
    [the defendants] made theirs.
    - 27 -
    "[t]here [wa]s no sufficient evidence here that Ranbaxy and Teva
    conspired together, [or] that they acted otherwise than in their
    own individual best interest."     Although the court "came within an
    ace" of granting the motion on causation as well, it decided to
    deny the motion for "prudential reasons" and let that question go
    to the jury.     The court did grant the defendants' motion on
    causation with regard to any theory of antitrust causation based
    on patent invalidity, as it found "no adequate evidence that any
    of these patents would be adjudicated invalid."              Earlier in the
    trial, the plaintiffs had already told the court that they would
    not pursue such a theory.
    To be sure of the accuracy and consequences of its ruling
    on patent invalidity, the court invited the parties to present
    further arguments on that issue following its initial ruling.           The
    court   subsequently   refined     its     judgment    regarding      patent
    invalidity.    Specifically, the court credited the plaintiffs'
    argument that, as a matter separate from the absolute validity of
    the Nexium patents, patent holders like AstraZeneca protect their
    patent monopoly and maximize profit in a world in which patent
    infringement   litigation   may    loom    but   has   not    taken   place.
    Accordingly, the court allowed the plaintiffs, independent of the
    ruling on patent invalidity, to argue that the defendants could
    have been incentivized to reduce the risk of patent invalidation
    -- for instance, by paying to delay the market entry of generics.
    - 28 -
    On November 24, 2014, Teva settled and dropped out of
    the suit, leaving only AstraZeneca and Ranbaxy as defendants.
    4.   Exclusion of Plaintiffs' Proposed Rebuttal Evidence
    At the close of the defendants' case on December 2, 2014,
    the plaintiffs unsuccessfully sought to admit rebuttal evidence,
    which included the McGuire Event Study that the court had already
    excluded; a report published by Federal Trade Commission ("FTC")
    staff and entitled "Pay-for-Delay: How Drug Company Pay-Offs Cost
    Consumers Billions"; and expert testimony from Dr. Keith Leffler.
    Leffler, an economist, proffered testimony that "virtually all
    Hatch-Waxman cases can be settled without reverse payments" and
    that it would have been in both AstraZeneca's and Ranbaxy's
    economic interest to enter into a payment-free settlement with a
    February 2012 entry date.   The court refused to admit any of this
    evidence "because it [was] not true rebuttal" and should have been
    introduced during the plaintiffs' case in chief.
    5.   Special Verdict Form and Jury Instructions
    The district court first provided the parties with the
    revised verdict form at a December 2, 2014 conference.   This form
    contained the following seven questions:
    1. Did AstraZeneca exercise market power within the
    relevant market?
    2. Did the settlement of the AstraZeneca-Ranbaxy
    patent litigation include a large and unjustified
    payment by AstraZeneca to Ranbaxy?
    - 29 -
    3. Was AstraZeneca's Nexium settlement with Ranbaxy
    unreasonably    anticompetitive,  i.e.   did   the
    anticompetitive    effects   of  that   settlement
    outw[ei]gh any pro-competitive justifications?
    4. Had   it    not   been   for    the   unreasonably
    anticompetitive settlement, would AstraZeneca have
    agreed with Ranbaxy that Ranbaxy might launch a
    generic version of Nexium before May 27, 2014?
    5. If so, what would be the effective date of such a
    license?
    6. a.   Had  it   not  been  for  the  unreasonably
    anticompetitive settlement, would Ranbaxy have
    agreed with Teva to launch a generic version of
    Nexium before May 27, 2014? b. If so, when would
    Teva have launched?
    7. If a generic version of Nexium had come to market,
    would an authorized generic have entered at or
    about the same time?
    After the court explained its revisions, it engaged in a colloquy
    with    the   parties,   which   focused,   in   relevant   part,   on   the
    plaintiffs' objection that Question 4 applied a legally incorrect
    "subjective" test for antitrust causation.
    The district court instructed the jury the next day.       On
    Question 4, the court explained that answering "yes" to the first
    three    questions    was   insufficient    because   "[j]ust   making     a
    deal . . . is not enough for liability[;] there has to be a harm."
    The court further explained that although the question mentioned
    by name AstraZeneca and Ranbaxy, it was "not necessarily just
    focusing on the AstraZeneca–Ranbaxy settlement":
    Now, the test here is an objective test. In other
    words I use the names "AstraZeneca" and "Ranbaxy"
    - 30 -
    because those are the folks we're talking about
    here, but the test is not what they did . . . we
    know what agreement they entered into, you would
    have found [in Question 3] that agreement is
    unreasonably anticompetitive. So then you're asked
    the question, "Well, suppose they didn't enter into
    such an agreement, suppose they were settling
    straight up without any anticompetitive effects,
    would that settlement license entry date have been
    earlier than the date they agreed to, May 27th,
    2014?"
    The court also reviewed Teva's role in the plaintiffs' theory --
    namely, that had AstraZeneca not made a reverse payment to Ranbaxy,
    their settlement agreement would have contained an earlier entry
    date, which would have allowed Teva to obtain that same earlier
    date or to partner with Ranbaxy for a joint launch of generic
    Nexium.     Finally, the court informed the jury that a "no" to any
    question meant that the jury should not consider any subsequent
    question.
    During the sidebar following the charge, each party
    objected to certain aspects of the court's instructions. The court
    had earlier warned that the parties had to raise their objections
    at the end of the charge to preserve them for appeal.             The
    plaintiffs' objections to Question 4 were limited to the district
    court's colloquial framing of that question.     They also objected
    to other aspects of the instructions unrelated to Question 4.
    6.   Plaintiffs' Closing Statement
    The plaintiffs' closing expressly reminded the jury of
    the "large and unjustified payment" from AstraZeneca to Ranbaxy.
    - 31 -
    Plaintiffs' counsel argued that "[i]t's large because it was worth
    about $690 million to Ranbaxy, or according to [one witness], about
    $300 million.      It was going to cost AstraZeneca, in terms of lost
    sales, about $500 million of its own revenues that it might be
    able to get from the sale of [an authorized generic]."                  The
    plaintiffs further urged the jury to draw inferences from that
    payment: "By the fact that there was a payment you can infer that
    there was a movement of that entry date.            Absolutely.    And [by]
    the fact that this payment was so large you can infer that the
    entry date was moved back and should have been earlier."
    Notwithstanding the court's judgment as a matter of law
    on the issue of patent invalidity, the plaintiffs' closing also
    questioned the strength of AstraZeneca's Nexium patents and the
    relevance     of    those    patents    to   the   defendants'    settlement
    agreement.    The closing emphasized that the two defendants denied
    "ever talk[ing] about the strengths and weaknesses of the patent
    in order to negotiate some kind of date."             Further, "[b]ecause
    . . . there was never a negotiation here where the two companies
    sat down and said we've got these claims on the patents . . .
    here's infringement issues, let's see how we can negotiate on the
    merits of this case a resolution," the plaintiffs urged the jury
    to find that the AstraZeneca-Ranbaxy deal consisted of "payoffs
    that   weren't     related   to   the   merits."    Upon   the   defendants'
    objections to the plaintiffs' characterization of "the patent
    - 32 -
    merits a[s] a coin flip" during the closing, the court reminded
    the jury that "on this record there is no evidence that any of
    these patents at the end of the day would have been held invalid."
    Finally, the plaintiffs' closing discussed at least two
    mechanisms through which the Ranbaxy reverse payment could have
    led to an antitrust injury in the form of a delayed generic launch.
    First, they explained that AstraZeneca faced a "major risk of
    potential at-risk launch . . . in late 2007 and early 2008" and
    thus had an incentive to settle with Ranbaxy to avoid that outcome.
    Next, the plaintiffs reminded the jury about the Lipitor analogy.
    Articulating    the   "striking"    similarities    between   Nexium   and
    Lipitor, the plaintiffs emphasized that generic Lipitor launched
    despite Ranbaxy's regulatory troubles, while generic Nexium did
    not, because the Lipitor settlement agreement did not contain a
    no-AG clause and thus provided for an earlier entry date compared
    to the Nexium settlement agreement.
    7.    Jury Verdict
    After deliberating for two and a half days, the jury
    returned a verdict for the defendants.         The jury answered "yes" to
    the first three questions, finding that the AstraZeneca-Ranbaxy
    settlement contained a "large and unjustified payment" and had an
    "unreasonably   anticompetitive"      market    impact.    But   the   jury
    answered "no" to Question 4, finding that the plaintiffs had failed
    to prove that AstraZeneca would have negotiated an entry date
    - 33 -
    earlier    than    May    27,   2014.      Heeding   the   court's    earlier
    instructions, the jury stopped after its "no" answer.
    C. Post-Trial Proceedings
    On December 31, 2014, the plaintiffs moved for a new
    trial based in part on allegedly contradictory evidence that
    Ranbaxy had presented in litigation against the FDA in December
    2014.    One week later, a subset of plaintiffs moved for a permanent
    injunction under Section 16 of the Clayton Antitrust Act, Pub. L.
    63-212, 
    38 Stat. 730
     (codified at 
    15 U.S.C. §§ 12-27
    , 
    29 U.S.C. §§ 52-53
    ).     The district court denied both motions.            See In re
    Nexium [Post-Trial Opinion], 309 F.R.D. at 134, 143.
    This appeal followed.
    IV.     ANALYSIS
    Plaintiffs have chosen to focus their appeal on the
    partial    grant   of    summary   judgment,   the   exclusion   of   certain
    evidence at trial, alleged errors in the district court's special
    verdict form and jury instructions, and the grant of judgment as
    a matter of law on the claim of overarching conspiracy. Plaintiffs
    argue that any one of these alleged errors entitles them to a new
    trial.
    We disagree and affirm the district court's evidentiary
    rulings, judgment as a matter of law on overarching conspiracy,
    and decision to structure the special verdict form and jury
    instructions in the manner that it did.            Further, in light of the
    - 34 -
    jury verdict and other critical developments at trial on the issue
    of patent invalidity, we decline to revisit the district court's
    summary judgment rulings.           It would be improper for an appeals
    court   to   wade    into    such   pretrial   matters   when,   as   here,    a
    confluence of the plaintiffs' trial strategy, the district court's
    rulings, and the jury verdict rendered harmless any alleged error
    at the summary judgment stage.
    A.   Evidentiary Rulings
    The plaintiffs challenge numerous evidentiary rulings of
    the district court.         We find no error and affirm.
    1.    Exclusion of McGuire's Event Study Testimony
    The plaintiffs argue that the district court committed
    reversible error by refusing to allow Dr. Thomas McGuire to testify
    for a third time after it concluded that the subject of his
    testimony, the Event Study, was inadmissible under Daubert.                   We
    review Daubert determinations for abuse of discretion.                  Ruiz-
    Troche v. Pepsi Cola of P.R. Bottling Co., 
    161 F.3d 77
    , 81 (1st
    Cir. 1998) (citing General Elec. Co. v. Joiner, 
    522 U.S. 136
    , 141-
    42 (1997)).       Federal Rule of Evidence 702 requires district courts
    to "ensur[e] that an expert's testimony both rests on a reliable
    foundation and is relevant to the task at hand" before admitting
    it into evidence.       Daubert, 
    509 U.S. at 597
    .        The district court,
    as gatekeeper, must "ensure that there is an adequate fit between
    - 35 -
    the expert's methods and his conclusions."           Samaan v. St. Joseph
    Hosp., 
    670 F.3d 21
    , 32 (1st Cir. 2012).
    We conclude on the merits4 that the district court did
    not abuse its discretion in excluding the Event Study and McGuire's
    corresponding testimony.        The court properly found that the Event
    Study methodology -- which purported to use econometric analysis
    of stock market data to "estimate an objective entry date without
    [a reverse] payment" -- did not fit the conclusions for which it
    was offered.       Although such studies had previously been "admitted
    on valuation, something much more germane to stock price," the
    study had questionable relevance to hypothesizing the outcome of
    a settlement agreement, especially one as crucial as the but-for
    entry date in a reverse-payment case.         Furthermore, when asked to
    offer an example of another study that had used the Event Study
    methodology to predict settlement terms, the plaintiffs could not
    produce anything but an unpublished, non-peer-reviewed working
    paper       that   McGuire   co-authored   during   the   course   of   this
    litigation. The exclusion of McGuire's Event Study testimony under
    these circumstances did not constitute an abuse of discretion.
    4 As a threshold matter, the defendants argue that the
    plaintiffs are judicially estopped from appealing the exclusion of
    McGuire's Event Study, as they agreed to give up that evidence to
    defeat the defendants' mistrial motion. We need not reach this
    claim.
    - 36 -
    2.    Exclusion of Other Aspects of McGuire's Testimony
    The    plaintiffs   also   accuse   the   district   court   of
    improperly forbidding McGuire from testifying about three other
    issues: (1) specific but-for entry dates, (2) "the purpose and
    effect of the side deals" between AstraZeneca and Ranbaxy, and
    (3) the exact size of the reverse payment from AstraZeneca to
    Ranbaxy.   We can quickly dispose of these arguments.
    First, as to McGuire's testimony on the but-for entry
    dates, examining the district court's decision in the context of
    the overall record makes clear that the exclusion did not prejudice
    the plaintiffs.      During McGuire's second testimony, which took
    place before the district court's mid-trial epiphany on the Ranbaxy
    reverse payment's relevance, the court did not allow McGuire to
    testify that Ranbaxy and Teva "would have been able to enter in
    2011" but for the reverse payments. This ruling did not constitute
    reversible error in light of events at trial that took place both
    before and after the court's epiphany.
    Even before its shift in thinking, the district court
    gave McGuire leeway to testify about Ranbaxy's economic incentives
    to enter into the settlement agreement with AstraZeneca.            That
    testimony, in turn, implied how the AstraZeneca-Ranbaxy settlement
    could have led to delayed generic entry.        In particular, McGuire
    testified, during his second time on the stand, that the contingent
    launch provision in Ranbaxy's settlement agreement diminished the
    - 37 -
    likelihood of subsequent ANDA filers seeking to enter the generic
    Nexium market.          "In fact," McGuire testified, "there were no
    subsequent ANDA filers that pursued this [generic entry] through
    litigation."           The    district     court     also    permitted      plaintiffs'
    counsel to ask McGuire whether he had "reach[ed] a conclusion as
    to    whether    Ranbaxy      had   an     economic       motive    to    agree    to   the
    [contingent launch] clause."               McGuire answered in the affirmative
    and,    over    an     objection,     was    allowed        to   elaborate     that     the
    contingent      launch       provision     "had     the   effect     of   reducing      the
    likelihood that Teva would challenge and break the bottleneck,
    which mean[t] for Ranbaxy[,] it became more likely that [it was]
    able to use [its] 180-day exclusivity period and make the profits
    associated with that."              Notwithstanding McGuire's inability to
    testify to exact but-for entry dates, the district court afforded
    him    great    latitude       to   give    testimony       on     Ranbaxy's      economic
    incentives to block other ANDA filers and thus delay generic entry.
    Next,    after   the   court's       adjustment       in   thinking,     it
    informed the parties that it would not allow McGuire to testify a
    third time out of principles of fairness and that the plaintiffs
    should consider this ruling's implications on their mistrial-
    motion calculus. In addition, independent of its rulings regarding
    McGuire, the court allowed testimony on but-for entry dates from
    another expert, Dr. Cheryl Blume, whom the court described as the
    plaintiffs' "lead witness" on this very issue.                      Blume testified as
    - 38 -
    part of the plaintiffs' case in chief over three days of trial
    (November 18 to 20).
    In the context of the court's rulings on McGuire and
    Blume, the plaintiffs continued to oppose a mistrial.           The record
    does not show that they made any objections that they should have
    been allowed to present cumulative evidence on specific but-for
    entry dates through McGuire in addition to Blume.          In short, the
    plaintiffs had an opportunity to present evidence on hypothetical
    earlier entry dates through Blume, and the district court was under
    no obligation to also permit McGuire to testify on that same issue.
    The plaintiffs' argument to the contrary seems to be little more
    than an effort to admit cumulative and weaker evidence.                See
    McDonald v. Fed. Labs., Inc., 
    724 F.2d 243
    , 248 (1st Cir. 1984);
    cf. Fed. R. Evid. 403 ("The [trial] court may exclude relevant
    evidence if its probative value is substantially outweighed by a
    danger of . . . unfair prejudice, confusing the issues, misleading
    the jury, undue delay, wasting time, or needlessly presenting
    cumulative evidence.").      Plaintiffs have not shown any prejudice
    resulting   from    the   district   court's   decision   not   to   permit
    cumulative evidence, particularly from a witness who had already
    been allowed to testify twice.
    Next,   the    alleged   errors    in   excluding    McGuire's
    testimony on the side deals and the size of the reverse payment
    were harmless in light of the jury verdict.          The "yes" answer to
    - 39 -
    Question 2 reflects the jury's finding that AstraZeneca made a
    large and unjustified payment to Ranbaxy.         Furthermore, as to the
    size of the reverse payment, although McGuire could not assign a
    specific dollar figure to the value of the reverse payment, the
    district court did allow him to testify that it was worth "hundreds
    of millions of dollars."
    3.   Pretrial Exclusion of Upadhye's Testimony
    The plaintiffs also fault the district court for its
    pretrial decision in limine to exclude testimony from Shashank
    Upadhye, who sought to provide "a real world business perspective
    on settlement negotiations for drug patent lawsuits."
    Before reaching the merits, we must point out that,
    despite the district court's clear instructions that its pretrial
    decisions were "not rulings" and that the parties "must make
    [their] objections known during the course of the trial," the
    plaintiffs did not renew at trial their objections to the court's
    in limine decision regarding Upadhye.         In fact, although the
    plaintiffs listed Upadhye as a witness whom they "m[ight] call" at
    trial, they never actually attempted to do so.                  Under these
    circumstances, the district court's in limine decision may not
    even serve as proper grounds for a reversal.        See, e.g., Littleton
    v. McNeely, 
    562 F.3d 880
    , 891 (8th Cir. 2009).
    But even if the plaintiffs had properly objected to the
    exclusion   of   Upadhye's   testimony,   there    would   be    no   error.
    - 40 -
    "Whether a witness is qualified to express an opinion is a matter
    left to the sound discretion of the trial judge."             McDonald, 
    724 F.2d at 248
     (quoting A. Belanger & Sons, Inc. v. U.S. for Use &
    Benefit of Nat'l U.S. Radiator Corp., 
    275 F.2d 372
    , 376 (1st Cir.
    1960)).     Here, the district court excluded Upadhye's proposed
    testimony because he was "not [an] economist[]" and "d[id] not
    have the requisite qualifications to testify."               That decision,
    especially given Upadhye's reliance on his general experience and
    his failure to cite any methodology undergirding his opinions, was
    not an abuse of discretion.          The district court may also have
    "regarded    [Upadhye's]      proffered   testimony   as    cumulative,"   as
    McGuire had already testified about the Ranbaxy reverse payment
    and Upadhye would have offered only a "real world" spin on that
    testimony.     Id.
    4.   Exclusion of Plaintiffs' Proposed Rebuttal Evidence
    The plaintiffs next seek reversal on the ground that the
    district court's exclusion of their "rebuttal" evidence was error.
    Not so.      "The principal objective of rebuttal is to permit a
    litigant to counter new, unforeseen facts brought out in the other
    side's case."        Faigin v. Kelly, 
    184 F.3d 67
    , 85 (1st Cir. 1999).
    "[T]he    decisions      as   to   what   constitutes      proper   rebuttal
    evidence . . . lie within the sound discretion of the trial judge
    and are subject to substantial deference."                 United States v.
    LiCausi, 
    167 F.3d 36
    , 52 (1st Cir. 1999).
    - 41 -
    The plaintiffs sought to admit three pieces of evidence,
    purportedly in an effort to rebut the testimony of two defense
    witnesses, "that AstraZeneca never 'express[ed] any willingness to
    agree to any' date other than May 27, 2014." The proposed rebuttal
    evidence consisted of (1) McGuire's Event Study testimony, which
    the district court had already rejected as part of the plaintiffs'
    case in chief; (2) an economic analysis of a no-payment settlement
    by another expert, Dr. Keith Leffler; and (3) a study published by
    FTC staff.   At oral argument, the plaintiffs insisted that their
    inability to admit any rebuttal evidence, coupled with other
    alleged errors of the district court, meant that "all the jury
    heard was some officers of [the defendants'] company saying they
    wouldn't do things differently."
    Contrary to the plaintiffs' statement, the district
    court properly refused to admit the plaintiffs' proposed rebuttal
    evidence, reasoning that it "was hardly true rebuttal testimony
    because establishing [the date on which the defendants would have
    agreed to a generic launch but for a reverse payment] was an
    essential part of the Plaintiffs' prima facie case." Indeed, given
    the centrality of this date to the entire litigation and especially
    to the plaintiffs' need to prove an antitrust injury, it was
    entirely foreseeable that the defendants would assert that the
    date would not have been earlier than May 27, 2014.    It was thus
    within the district court's discretion to rule that the defendants'
    - 42 -
    testimony to that effect offered nothing "new" to warrant use of
    the plaintiffs' proffered evidence as rebuttal.       See Faigin, 
    184 F.3d at 85
    .
    The   plaintiffs   respond    by   emphasizing   the     unique
    circumstances of this trial.   Given that the district court first
    directed them to focus their case on the Teva reverse payment but
    radically adjusted its understanding mid-trial to recognize the
    relevance of the Ranbaxy reverse payment, the plaintiffs argue
    that the district court was required to give them an opportunity,
    at rebuttal, "to present evidence relating to the newly revived
    issue."   Alberty-Vélez v. Corporación de Puerto Rico para la
    Difusión Pública, 
    242 F.3d 418
    , 422 (1st Cir. 2001) (quoting Leddy
    v. Standard Drywall, Inc., 
    875 F.2d 383
    , 386 (2d Cir. 1989)).        But
    the record does not support the plaintiffs' contention that the
    district court did not afford them such an opportunity.          Instead,
    the record portrays the plaintiffs' neglect in seeking to admit
    relevant testimony after the court course-corrected (with the
    exception of McGuire's Event Study, which was supportably excluded
    on Daubert grounds, as discussed above).
    The plaintiffs made no effort to seek admission of the
    FTC study or Leffler's testimony as part of their case in chief,
    even though they had two days between the district court's epiphany
    and the end of their case in chief to do so.           They offer no
    explanation on appeal of their failure to seek admission of the
    - 43 -
    FTC study before resting their case.             And while they do explain
    that they could not call Leffler on short notice because he resided
    in Seattle, the record does not indicate that the plaintiffs
    brought    this   geographical      limitation   to    the   district      court's
    attention.     In short, the plaintiffs had a window of opportunity
    to seek admission of the FTC study and Leffler's testimony before
    resting their case.      Given their own failure to do so, we conclude
    that it was within the district court's discretion to refuse to
    admit that evidence, which properly belonged in the plaintiffs'
    case in chief, and not in their rebuttal.
    B.   Judgment as a Matter of Law on Overarching Conspiracy
    The plaintiffs argue that the district court erroneously
    granted judgment as a matter of law ("JMOL") on the overarching
    conspiracy claim.       They argue that they had proved the existence
    of contingent launch provisions in the defendants' settlement
    agreements, that this evidence had sufficed to survive summary
    judgment, and that thus it necessarily was enough to defeat JMOL.
    But this reasoning mixes apples and oranges.
    We review de novo a district court's decision to grant
    JMOL.     Malone v. Lockheed Martin Corp., 
    610 F.3d 16
    , 19 (1st Cir.
    2010).      An antitrust conspiracy claim under Section 1 of the
    Sherman    Act,   
    15 U.S.C. § 1
    ,   requires     evidence   of   an   actual
    "'agreement[]' -- whether tacit or express."             White v. R.M. Packer
    Co., 
    635 F.3d 571
    , 575 (1st Cir. 2011).          "[I]ndependent decisions,
    - 44 -
    even if they lead to the same anticompetitive result as an actual
    agreement among market actors," are insufficient to sustain a
    Section 1 conspiracy claim.     
    Id.
        As a result, mere parallel
    conduct and "[e]ven 'conscious parallelism,' a common reaction of
    firms in a concentrated market that recognize their shared economic
    interests and their interdependence with respect to price and
    output decisions[,] is not in itself unlawful."    Bell Atl. Corp.
    v. Twombly, 
    550 U.S. 544
    , 553–54 (2007) (alterations omitted)
    (quoting Brooke Grp. Ltd. v. Brown & Williamson Tobacco Corp., 
    509 U.S. 209
    , 227 (1993)).
    The law distinguishes illegal tacit agreements from
    "mere conscious parallelism" through evidence of "uniform behavior
    among competitors, preceded by conversations implying that later
    uniformity might prove desirable or accompanied by other conduct
    that in context suggests that each competitor failed to make an
    independent decision."   White, 
    635 F.3d at 576
     (emphasis added)
    (quoting Brown v. Pro Football, Inc., 
    518 U.S. 231
    , 241 (1996));
    see also Dickson v. Microsoft Corp., 
    309 F.3d 193
    , 203 (4th Cir.
    2002) (concluding that a "rimless wheel conspiracy" -- in which
    "various defendants enter into separate agreements with a common
    defendant, but where the defendants have no connection with one
    another, other than the common defendant's involvement in each
    transaction" -- is "not a single, general conspiracy but instead
    amounts to multiple conspiracies between the common defendant and
    - 45 -
    each of the other defendants" (citing Kotteakos v. United States,
    
    328 U.S. 750
    , 755 (1946))).
    The     plaintiffs   point    to   parallel    contingent    launch
    provisions      in    AstraZeneca's       settlements   with    each     generic
    manufacturer as evidence of the existence of one overarching
    conspiracy.        Under these provisions, the generic manufacturers
    agreed to delay launching generic Nexium until May 27, 2014, or an
    earlier date on which AstraZeneca or a court order permitted them
    to do so.    Beyond the provisions, however, the plaintiffs fail to
    present any evidence that Ranbaxy and Teva agreed to engage in
    anticompetitive conduct.
    Given the dearth of additional evidence, the district
    court correctly recognized that "[t]here is no sufficient evidence
    here that Ranbaxy and Teva conspired together, that they acted
    otherwise than in their own individual best interest."                   Indeed,
    some evidence that Ranbaxy and Teva, independent of AstraZeneca,
    agreed to engage in anticompetitive conduct was critical because
    self-interest could explain equally well why each might execute a
    contingent launch provision.              After all, as defendant Ranbaxy
    explains, "[e]ach generic company would have wanted to ensure that
    no other generic preceded its entry into the market -- and would
    have   sought      that   assurance   by   obtaining    a   contingent    launch
    provision in its settlement agreement."            In short, without proving
    "the existence of a 'rim' to the wheel in the form of an agreement
    - 46 -
    among" the generic manufacturers, the plaintiffs did not have a
    viable claim of overarching conspiracy to survive JMOL.       United
    States v. Apple, Inc., 
    791 F.3d 290
    , 314 n.15 (2d Cir. 2015).
    The three cases that the plaintiffs string cite do not
    alter our assessment.    See United States v. Masonite Corp., 
    316 U.S. 265
     (1942); Interstate Circuit v. United States, 
    306 U.S. 208
    (1939); Toys "R" Us, Inc. v. FTC, 
    221 F.3d 928
     (7th Cir. 2000).
    The cases do not say, as plaintiffs argue, that interdependent
    conduct,   absent   more,   suffices   to     establish   overarching
    conspiracy.    Properly read, they in fact reinforce the opposite
    proposition.
    First, contrary to the plaintiffs' argument, Masonite
    makes no holding on horizontal conspiracy.       There, Masonite, a
    manufacturer of building materials, developed a product called
    hardboard and obtained patents for both the product and the process
    for manufacturing it.   
    316 U.S. at
    267–68.   When competitors began
    manufacturing hardboard, Masonite sued each of them for patent
    infringement, 
    id.
     at 268–70, but eventually settled each suit on
    identical terms, including a price-fixing term, 
    id.
     at 270–73.
    The Supreme Court upheld the district court's factual findings
    that each of Masonite's competitors had "acted independently of
    the others, negotiated only with Masonite, desired the agreement
    regardless of the action that might be taken by any of the others,
    did not require as a condition of its acceptance that Masonite
    - 47 -
    make   such    an   agreement    with   any    of   the   others,    and     had   no
    discussions with any of the others."             
    Id. at 275
    .       The Court then
    held that the individual vertical contracts between Masonite and
    each competitor violated § 1 of the Sherman Act.                   Id.     That was
    the extent of Masonite's holding.              Indeed, to read Masonite as
    having    found     an    overarching   horizontal        conspiracy     would     be
    "nonsensical"       because    "an   essential      conspiracy     element    [wa]s
    missing -- namely, a motive for joint action or interdependence."
    6 Areeda & Hovenkamp, Antitrust Law ¶ 1427d (2d ed. 2003).
    The second case that the plaintiffs cite, Interstate
    Circuit, is also of no help to their claim of error.                  Unlike this
    case, in which the district court found no evidence to infer any
    agreement between Ranbaxy and Teva, the Court in Interstate Circuit
    saw enough circumstantial evidence to find a "tacit agreement"
    among all defendants.         
    306 U.S. at 225-27
    ; White, 
    635 F.3d at 576
    .
    There, "a dominant movie theater company sent a letter openly
    addressed to all eight major national film distributors stating
    that it would show a distributor's films only if the distributor
    imposed   certain        restrictions   on    later   runs   of    the   films     in
    secondary theaters."          White, 
    635 F.3d at 576
    .             "[T]he economic
    context made it clear that all eight needed to act uniformly or
    all would lose business, and all eight did in fact impose the
    conditions."        
    Id.
        By contrast, here, the district court found
    - 48 -
    that the plaintiffs had presented insufficient evidence from which
    to infer even a tacit agreement.
    Finally, Toys "R" Us is also inapposite because evidence
    in that case showed that entering into parallel agreements with
    Toys "R" Us ("TRU") was against each toy manufacturer's interest
    unless all of them did so.     TRU, "a giant in the toy retailing
    industry," had executed agreements with various toy manufacturers
    that TRU would carry the manufacturers' toys only if they promised
    to curb sales to warehouse club stores like Costco that sold toys
    at lower prices than did TRU.      221 F.3d at 930.     The Seventh
    Circuit affirmed an FTC finding of a horizontal conspiracy among
    the toy manufacturers for two reasons.   First, "the record . . .
    included the direct evidence of communications" among the toy
    manufacturers.   Id. at 935.   Second, the evidence showed that it
    was actually against the toy manufacturers' economic interest to
    curb sales to warehouse clubs unless they all did so:
    The evidence showed that the companies wanted to
    diversify from TRU, not to become more dependent
    upon it; it showed that each manufacturer was
    afraid to curb its sales to the warehouse clubs
    alone, because it was afraid its rivals would cheat
    and gain a special advantage in that popular new
    market niche. . . . [T]he only condition on which
    each toy manufacturer would agree to TRU's demands
    was if it could be sure its competitors were doing
    the same thing.
    Id. at 936.   The record in this case contains no such evidence.
    - 49 -
    In Interstate Circuit and Toys "R" Us, there were "plus
    factors" -- i.e. "additional facts or factors required . . . as a
    prerequisite     to   finding   that   parallel   action   amounts   to   a
    conspiracy."     6 Areeda & Hovenkamp, supra, ¶ 1433e ("Even those
    courts that say that conscious parallelism is a factor 'to be
    weighed, and generally to be weighed heavily' in establishing a
    § 1 violation are usually speaking about fact situations in which
    there is other evidence of conspiracy." (emphasis added) (footnote
    omitted)).
    The plaintiffs' briefs do not focus on the lack of
    evidence to prove their claim of overarching conspiracy.        Instead,
    they primarily argue that the district court initially ruled in
    their favor at summary judgment and that the court should not have
    reversed itself at the JMOL stage.         In so doing, the plaintiffs
    fail to consider that the summary judgment ruling may have been in
    error.   Nor do they recognize that the JMOL reasoning, not the
    summary judgment reasoning, has found agreement in at least two
    other trial courts that have considered the issue. See In re Actos
    End Payor Antitrust Litig., No. 13-CV-9244(RA), 
    2015 WL 5610752
    ,
    at *24 (S.D.N.Y. Sept. 22, 2015); King Drug Co. of Florence, Inc.
    v. Cephalon, Inc., No. 2:06-CV-1797, 
    2014 WL 2813312
    , at *14 (E.D.
    Pa. June 23, 2014).     There was no error.
    Finally, the Individual Retailer plaintiffs misrepresent
    the district court's opinion denying them a new trial.               They
    - 50 -
    contend that after the court recognized its summary judgment ruling
    as "a bit too sweeping," it nonetheless "reverted to the summary
    judgment rationale . . . that the evidence was sufficient to
    support a finding that 'AstraZeneca was the hub of a hub-and-spoke
    conspiracy.'" Quoted in full, however, the district court actually
    reaffirmed its JMOL ruling, noting that "[a]t trial, the evidence
    warranted, at most, a finding that AstraZeneca was the hub of a
    hub-and-spoke conspiracy with the three generic manufacturers
    acting as competitors vis-à-vis each other, not conspirators."   In
    re Nexium [Post-Trial Opinion], 309 F.R.D. at 115 n.13 (emphasis
    added).   In other words, the court recognized that although the
    evidence might show one conspiracy between AstraZeneca and Ranbaxy
    and another disparate conspiracy between AstraZeneca and Teva, the
    evidence was legally insufficient to tie all three players in an
    overarching conspiracy.   We find no error in the district court's
    decision to grant JMOL on the overarching conspiracy claim in light
    of the plaintiffs' inability to cite any supporting evidence other
    than the parallel contingent launch provisions.
    C.   Special Verdict Form and Jury Instructions
    The final verdict form that went to the jury asked seven
    questions and was structured so that a "no" answer to any question
    meant that the jury could stop considering the rest.   As relevant
    here, the first four questions asked:
    - 51 -
    1. Did AstraZeneca exercise market power within the
    relevant market?
    2. Did the settlement of the AstraZeneca-Ranbaxy
    patent litigation include a large and unjustified
    payment by AstraZeneca to Ranbaxy?
    3. Was AstraZeneca's Nexium settlement with Ranbaxy
    unreasonably    anticompetitive,  i.e.   did   the
    anticompetitive    effects   of  that   settlement
    outw[ei]gh any pro-competitive justifications?
    4. Had   it    not   been   for    the   unreasonably
    anticompetitive settlement, would AstraZeneca have
    agreed with Ranbaxy that Ranbaxy might launch a
    generic version of Nexium before May 27, 2014?
    On appeal, the plaintiffs argue that Question 4 impermissibly
    "require[d] a specific factual sequence of causation," that it was
    duplicative of Question 3, that it erroneously posed a "subjective"
    test about the intent of the defendants, and that its wording was
    "confusing" and "misled the jury."     The defendants respond that
    all of these objections were either waived or forfeited.
    If a party fails to preserve its objections to jury
    instructions after the jury is charged, those objections are
    forfeited on appeal and reviewed only for plain error.   Booker v.
    Mass. Dep't of Pub. Health, 
    612 F.3d 34
    , 42 (1st Cir. 2010).   Plain
    error, "a hard-to-meet standard," requires the appellant to show
    "that '(1) an error occurred (2) which was clear or obvious and
    which not only (3) affected the [appellant's] substantial rights,
    but also (4) seriously impaired the fairness, integrity, or public
    reputation of the judicial proceedings.'"      Tasker v. DHL Ret.
    - 52 -
    Savings Plan, 
    621 F.3d 34
    , 40–41 (1st Cir. 2010) (alteration in
    original) (quoting Dávila v. Corp. de P.R. Para La Difusión
    Pública, 
    498 F.3d 9
    , 14–15 (1st Cir. 2007)).
    Furthermore, "with respect to special verdicts, 'the law
    is perfectly clear that parties waive any claim of internal
    inconsistency by failing to object after the verdict is read and
    before the jury is discharged.'"            Trainor v. HEI Hosp., LLC, 
    699 F.3d 19
    , 34 (1st Cir. 2012) (alterations omitted) (quoting Peckham
    v. Cont'l Cas. Ins. Co., 
    895 F.2d 830
    , 836 (1st Cir. 1990)).                This
    has been an "iron-clad rule" in our circuit.              Rodriguez-Garcia v.
    Mun. of Caguas, 
    495 F.3d 1
    , 9 (1st Cir. 2007).              Although we could
    altogether decline to hear the plaintiffs' arguments about the
    verdict form on waiver grounds, the FTC's amicus brief highlights
    the importance of straightening out the conflation of antitrust
    violation and antitrust injury that crept into the district court's
    post-trial opinion and into some of the parties' arguments on
    appeal. We accept the FTC's invitation to provide greater clarity.
    Two of the plaintiffs' four objections seem to arise
    from       this    wrongful   conflation.      The   plaintiffs   protest   that
    Question 4 was duplicative of Question 3 and that Question 4 held
    the plaintiffs to an impermissibly stringent causation standard.5
    5  In their proposed special jury verdict form, the
    plaintiffs suggested precisely the same split in questions between
    antitrust violation and antitrust injury (in the form of a delayed
    generic entry).
    - 53 -
    Neither argument holds water, and in fact each shows that the
    plaintiffs may have obscured the clear law that, as private
    plaintiffs seeking damages, they must prove not only an antitrust
    violation but also an antitrust injury that allows recovery of
    damages.6
    Private plaintiffs and the FTC as government enforcer
    stand in different shoes.      Under the governing antitrust statutes,
    the FTC is empowered to directly enforce the substantive antitrust
    laws.       See 
    15 U.S.C. § 45
    (a)(2).       Meanwhile, private plaintiffs
    derive their authority to sue from Section 4 or 16 of the Clayton
    Act and must therefore satisfy the additional evidentiary burdens
    that those provisions impose.         See 
    id.
     §§ 15, 26.     As the FTC's
    amicus brief aptly explains, "[t]his distinction is rooted in
    public policy.      The interest of private plaintiffs is to remediate
    an injury they have suffered or may suffer.           The interest of the
    government is to 'prevent and restrain' violations of the antitrust
    laws along with the attendant social costs such violations can
    cause."
    The   Supreme   Court   has    consistently   held   private
    plaintiffs to this standard of proving both antitrust violation
    and antitrust injury.         See, e.g., Atl. Richfield Co. v. USA
    6 Because the plaintiffs do not appeal the district
    court's denial of their post-trial motion for an injunction, they
    evidently seek a new trial in order to recover damages.
    - 54 -
    Petroleum     Co.,     
    495 U.S. 328
    ,     344    (1990)    ("'[P]roof        of   [an
    antitrust] violation and of antitrust injury are distinct matters
    that must be shown independently.'                  For this reason, . . . the
    right of action under § 4 of the Clayton Act is available only to
    those private plaintiffs who have suffered antitrust injury."
    (quoting Areeda & Hovenkamp, Antitrust Law ¶ 334.2c (1989 Supp.))).
    A private plaintiff seeking monetary relief must show actual,
    quantifiable       damages     "by   reason    of"    the   antitrust       violation.
    Associated Gen. Contractors of Cal., Inc. v. Cal. State Council of
    Carpenters, 
    459 U.S. 519
    , 543 (1983); see also Brunswick Corp. v.
    Pueblo    Bowl-O-Mat,        Inc.,   
    429 U.S. 477
    ,    489    (1977)    (defining
    "antitrust injury" as "injury of the type the antitrust laws were
    intended      to   prevent     and   that     flows    from       that   which    makes
    defendants' acts unlawful").
    Assessed under this framework, Questions 3 and 4 are
    neither duplicative nor both aimed at causation.                         Rather, the
    former asks the jury about antitrust violation, while the latter
    asks about antitrust injury. The jury's "yes" answers to Questions
    2   and   3   (large    and    unjustified      payment     with    anticompetitive
    effects)      confirm    its    finding      that    some     antitrust      violation
    resulted from the AstraZeneca-Ranbaxy settlement.                    Question 4, by
    contrast, inquires whether these private plaintiffs have suffered
    an "injury of the type the antitrust laws were intended to prevent"
    by asking whether Ranbaxy (in partnership with Teva) would have
    - 55 -
    launched a generic earlier than May 27, 2014 but for the antitrust
    violation found in Question 3.       Brunswick, 
    429 U.S. at 489
    .          The
    "no" answer to Question 4 thus confirms the jury's finding that
    notwithstanding    the   existence   of    an    antitrust   violation,   the
    plaintiffs failed to establish an antitrust injury that entitled
    them to monetary relief.
    As Questions 3 and 4 played discrete and independently
    necessary roles in adjudicating an antitrust suit brought by
    private plaintiffs, we reject the plaintiffs' protests that the
    questions led to an "absurd" outcome.           There was nothing absurd in
    the jury verdict.        In fact, this circuit has reached similar
    conclusions in past antitrust cases.               See, e.g., Ocean State
    Physicians Health Plan, Inc. v. Blue Cross & Blue Shield of R.I.,
    
    883 F.2d 1101
    , 1105 (1st Cir. 1989) (observing that district court
    granted a renewed motion for JMOL in defendant's favor in part
    because "the jury's award of 'no damages' on the antitrust claim
    meant that plaintiffs had failed to prove that they had been
    injured by any illegal conduct by [the defendant]").
    The plaintiffs next object that Question 4 erroneously
    used the defendants' names and framed the relevant inquiry as a
    subjective, rather than an objective, test.             The record refutes
    this   argument.    After   the   plaintiffs       initially   raised   these
    concerns at the December 2, 2014 conference, the court clarified
    to the jury that "the test here is an objective test.              In other
    - 56 -
    words[,] I use the names 'AstraZeneca' and 'Ranbaxy' because those
    are the folks we're talking about here, but the test is not what
    they did."       The plaintiffs failed to renew their objections
    following these instructions.       Examining Question 4 in the context
    of the verdict form and jury instructions "as a whole," Johnson v.
    Teamsters Local 559, 
    102 F.3d 21
    , 28 (1st Cir. 1996), we conclude
    that the use of defendants' names did not constitute reversible
    error.
    The    plaintiffs   lastly      argue    that   Question    4   was
    confusingly worded and capable of multiple "legally erroneous"
    interpretations.     This objection suffers from the same defect as
    the others in that it was not preserved during the post-charge
    sidebar. The forfeited argument is unable to withstand plain error
    review,   especially    when   examined       in    the    context    of   the
    comprehensive instructions that the court provided to facilitate
    the   jury's   understanding   of    the    verdict    form.      First,   the
    plaintiffs'    suggestion   that    the    jury    could   have   interpreted
    Question 4 to be asking "whether AstraZeneca would allow Ranbaxy
    to get Ranbaxy's product to market" is meritless in light of the
    court's jury charge:
    The plaintiffs' claim is not that Ranbaxy would
    have launched, no evidence of that, their claim is
    that had AstraZeneca not made a large payment to
    Ranbaxy, they would have settled with a date for
    generic entry before May 27th, 2014. . . .     And
    that Teva then would have obtained the same or
    - 57 -
    earlier date . . . or that . . . Teva would have
    made a deal with Ranbaxy allowing Teva to launch.
    Likewise, the plaintiffs' concern that Question 4 imprecisely used
    the phrase "anticompetitive settlement," rather than "large and
    unjustified      payment,"   is    alleviated    by   jury   instructions
    explaining how the presence of a large and unjustified payment in
    a    paragraph   IV   litigation   settlement   renders   that   settlement
    anticompetitive.
    Perhaps the verdict form was inartfully phrased.         But in
    the context of the thorough jury instructions and the plaintiffs'
    own failure to preserve objections, the plaintiffs cannot argue
    that any phrasing imperfection "seriously impaired the fairness,
    integrity, or public reputation of the judicial proceedings."

    498 F.3d at
    14–15).
    D.    Summary Judgment
    We finally arrive at the core of the plaintiffs' appeal.
    The plaintiffs argue that they had but one antitrust causation
    theory at trial: "In this regulatory climate, generics will get to
    market in some way, and we can't know exactly how."          The district
    court erred, they say, in prematurely cutting off at summary
    judgment many causal mechanisms through which they could have
    proved this theory to a jury.          The defendants respond in three
    ways: (1) the plaintiffs' theory of antitrust causation is actually
    a hodgepodge of disparate theories, none of which independently
    - 58 -
    proves causation, (2) later events at trial moot any potential
    summary judgment error, and (3) the summary judgment ruling was
    correct on its merits.
    Even accepting dubitante the level of generality at
    which the plaintiffs characterize their causation theory, we agree
    with the defendants that any error at summary judgment was rendered
    harmless by the jury verdict and by later trial proceedings on the
    issue of patent invalidity.      We are satisfied that the evidence in
    support of even those causal mechanisms purportedly excluded at
    summary judgment was in fact put before the jury, as that evidence
    was   relevant   under   other   concededly    admitted   theories.    The
    district court recognized the relevance of that evidence and
    generously    admitted   much    of    it   notwithstanding   the   summary
    judgment ruling (which it later reversed).
    Plaintiffs identify four causal theories they say were
    cut off at summary judgment.          First, Ranbaxy could have launched
    its generic Nexium at risk before February 2009.              Second, Teva
    could have won a final, nonappealable judgment in its paragraph IV
    suit against AstraZeneca, thereby forcing Ranbaxy to launch its
    generic within 75 days or forfeit its exclusivity, which would
    have allowed Teva to launch before May 2014.         Third, Ranbaxy could
    have negotiated an earlier license date with AstraZeneca and
    launched (either alone or in partnership with Teva) before May
    2014.   Finally, Ranbaxy could have negotiated an earlier license
    - 59 -
    date   with   AstraZeneca    and    then     forfeited    its   first-filer
    exclusivity, which would have allowed another manufacturer like
    Teva to launch before May 2014.
    Ordinarily, "[w]e review the merits of the entry of
    partial summary judgment de novo."         Vélez v. Awning Windows, Inc.,
    
    375 F.3d 35
    , 41 (1st Cir. 2004).       But we have refused to "reenter
    th[e] morass" of summary judgment where it was "perfectly clear
    that, even if [a plaintiff's claim] should not have been dismissed
    on partial summary judgment, any such mistake was harmless, given
    the jury's verdict in [the defendant's] favor on [other claims]
    addressed to the very same [factual circumstances]."            Fite v. Dig.
    Equip. Corp., 
    232 F.3d 3
    , 6 (1st Cir. 2000).             We have so held in
    the antitrust context.      See Fraser v. Major League Soccer, LLC,
    
    284 F.3d 47
    , 60-61 (1st Cir. 2002).
    An examination of the four supposedly foreclosed causal
    mechanisms, in light of later events at trial, reveals that the
    outcome would have been in the defendants' favor even had the
    mechanisms been explicitly put in questions to the jury.                 In
    particular, the first two mechanisms were mooted by the district
    court's grant of JMOL on any theory involving the invalidity of
    AstraZeneca's patents.      Indeed, the argument that Ranbaxy would
    have incurred the risk of launching at risk or that Teva would
    have won its paragraph IV suit against AstraZeneca depends on the
    theory that AstraZeneca's Nexium patents were invalid or not
    - 60 -
    infringed by a generic version.   The district court's JMOL ruling,
    however, found "no adequate evidence that any of [the Nexium]
    patents would be adjudicated invalid."      Accordingly, even if the
    district court had allowed the plaintiffs to present these two
    causal mechanisms at trial, the court's later judgment would have
    yielded the same outcome in favor of the defendants.
    Plaintiffs respond that they should not have to prove
    patent invalidity or noninfringement to be able to present their
    at-risk launch causation theory.        They principally rely on two
    circuit cases to advance this argument, but to no avail.      See In
    re Cardizem CD Antitrust Litig., 
    332 F.3d 896
     (6th Cir. 2003);
    Andrx Pharm., Inc. v. Biovail Corp. Int'l, 
    256 F.3d 799
     (D.C. Cir.
    2001). Both of these cases were decided before the Supreme Court's
    Actavis decision, which may call into question aspects of their
    analyses.    Even assuming that the two decisions survive Actavis,
    they are still inapposite to our inquiry because both cases
    evaluated allegations of antitrust injury at the Rule 12(b)(6)
    stage.   See In re Wellbutrin XL Antitrust Litig., 
    133 F. Supp. 3d 734
    , 765 n.46 (E.D. Pa. 2015), appeal pending, No. 15-3559 (3d
    Cir.).   In In re Cardizem, for instance, the Sixth Circuit held
    that the defendants' argument -- that their decision to stay out
    of the generic market was motivated not by a reverse payment, but
    rather by a fear of damages resulting from patent infringement
    litigation -- "merely raise[d] a disputed issue of fact that [could
    - 61 -
    not] be resolved on a motion to dismiss."          
    332 F.3d at 900
    .     The
    Cardizem court did not altogether reject the potential relevance
    of patent invalidity or noninfringement evidence in evaluating the
    viability of an antitrust-injury theory based on an at-risk launch.
    So too in Andrx, 
    256 F.3d at 805
    , and United Food & Commercial
    Workers Local 1776 v. Teikoku Pharma USA, Inc., 
    74 F. Supp. 3d 1052
    , 1074 (N.D. Cal. 2014), yet another case that the plaintiffs
    cite.7
    In re Wellbutrin XL, a post-Actavis decision at the
    summary judgment stage, is persuasive.         
    133 F. Supp. 3d 734
    .
    There,   the   district   court   granted   summary    judgment   to    the
    defendants, who were producers and distributors of a branded
    antidepressant    drug,   on   the   plaintiffs'     at-risk   theory    of
    antitrust injury because the plaintiffs proffered no evidence of
    patent invalidity or noninfringement.       
    Id.
     at 764–67.      The court
    acknowledged that, if shown, "[t]he existence of a valid and
    uninfringed patent would interfere with the plaintiffs' chain of
    causation: a valid patent independently precludes competition
    apart from any agreement and an 'at risk' launch is unlawful absent
    7    In fact, the district court in Teikoku expressly
    distinguished In re Nexium, describing it as "a case where the
    generic manufacturer moved for summary judgment, and offered
    unrebutted evidence 'that an at risk launch was "unlikely" and
    "extremely risky."'" 74 F. Supp. 3d at 1074. In contrast, Teikoku
    dealt with "a motion to dismiss and defendants cite[d] to no
    comparable evidence that [wa]s properly before the [c]ourt at
    th[at] juncture." Id.
    - 62 -
    a later finding of patent invalidity or non-infringement."               Id. at
    764 (citation and alterations omitted).
    But there, as here, the plaintiffs did not present such
    evidence that the brand-name's patents would have been declared
    invalid or that an at-risk launch would not have infringed the
    patents.     And without such evidence, the "patent served as an
    independent regulatory bar to [a generic's] launch."               Id. at 767.
    So too here. Upon the conclusion of the plaintiffs' case in chief,
    the district court saw no evidence that would allow the plaintiffs
    to overcome the likelihood that AstraZeneca's patents, not its
    reverse payment to Ranbaxy, were the bar to a generic launch.              The
    district court thus did not err by requiring some evidence of the
    patents'     invalidity     or    noninfringement   before    allowing     the
    plaintiffs to pursue an at-risk launch theory.
    Furthermore,     the   district   court's   ruling     on   patent
    invalidity did not prejudice the plaintiffs, for two reasons.
    First, the plaintiffs are simply wrong to insist that the district
    court decided and ruled out of the case the issue of patent
    invalidity     at   summary      judgment.     In   fact,    the    plaintiffs
    acknowledged the availability of that line of reasoning -- and
    their strategic choice not to pursue it -- at a conference on the
    second day of trial: "We don't plan on proving a patent case inside
    of an antitrust case. . . .          [W]e do not plan to be proving that
    Teva would have won the [paragraph IV] litigation." The plaintiffs
    - 63 -
    then reaffirmed their strategic choice on November 20, 2014, at
    the same conference during which they opposed the defendants'
    motion for a mistrial.       At that conference, they assented to the
    court's characterization of their position as not having "proved
    that the patents would have been declared invalid, and [arguing]
    that that plays no role in this [trial]."
    The district court's statements during trial likewise
    reveal its consistent understanding that the summary judgment
    ruling    did   not   prevent     the    plaintiffs   from     offering   patent
    invalidity evidence if they chose to do so.             For instance, in its
    initial instructions to the jury at the beginning of trial, the
    district    court     explained    that    the    plaintiffs    would   have   to
    "convince [the jury] . . . that Teva entered into its deal with
    AstraZeneca, staying out of the market, letting AstraZeneca charge
    its supracompetitive prices for its branded Nexium product, and if
    it hadn't done that, it could . . . have defeated the patent,
    AstraZeneca's patents," received FDA approval, and partnered with
    Ranbaxy to jointly launch a generic.             The district court's view of
    the impact of its summary judgment ruling on patent invalidity did
    not change by the end of trial.             At the December 2, 2014 charge
    conference, it reminded the plaintiffs: "I think that you will
    find, when you look at the record, I've never prevented the patent
    evidence[;] I've said you have to lay an adequate foundation for
    it."     Because the ruling on patent invalidity did not take place
    - 64 -
    until after the plaintiffs' case in chief, at the JMOL stage, the
    timing of the ruling could not have foreclosed any evidence that
    the plaintiffs wished to put forth at trial. Any decision to limit
    evidence on patent invalidity was a voluntary and strategic choice
    on the plaintiffs' part.
    Second, even after the JMOL ruling, the district court
    was careful to point out, and correctly so, that its decision did
    not foreclose the plaintiffs from making any arguments based on
    AstraZeneca's assessment of risk to its patent monopoly.                  That is,
    the court recognized that regardless of the absolute validity or
    invalidity     of     patents,   business    players     make   reverse   payment
    decisions in an environment in which that validity has not yet
    been adjudicated.        They take into account the risk of litigation
    and the possibility that patents may be adjudicated invalid or
    uninfringed.        The court explained this distinction between patent
    invalidity and assessment of risk to the jury: "I went into the
    case thinking . . . that one of the things the plaintiffs had to
    prove   was    that    Teva   would   have   won   its    patent   case   against
    AstraZeneca.        And I've come to think now that legally that's not
    key, that's not what the plaintiffs have to prove."                In sum, while
    the JMOL ruling on patent invalidity mooted the causal mechanisms
    based on at-risk launch and Teva's ability to win a paragraph IV
    litigation against AstraZeneca, the JMOL ruling did not prejudice
    the plaintiffs' argument that the defendants had incentives to
    - 65 -
    violate antitrust laws.        Indeed, the jury verdict confirms this
    lack of prejudice, as it found that AstraZeneca made a large and
    unjustified payment to Ranbaxy and that their settlement agreement
    had unreasonably anticompetitive effects.
    As for the next two causal mechanisms claimed to have
    been cut off at summary judgment, the jury's "no" answer to
    Question 4 renders any error harmless.       That answer reflected the
    jury's finding that AstraZeneca would not have agreed to settlement
    terms with a license date earlier than May 27, 2014, the date on
    which two of its medical patents expired.             In light of that
    finding, it made no difference to the outcome of the trial whether
    the plaintiffs were able to present their theory that Ranbaxy could
    have negotiated an earlier license date with AstraZeneca and
    themselves launched or allowed Teva to launch before May 2014.
    The plaintiffs respond that the jury had insufficient
    evidence upon which to answer Question 4 differently.            At oral
    argument,   the   plaintiffs    emphasized   that   their   inability   to
    introduce evidence on the possibility of a Ranbaxy or Teva at-risk
    launch,8 or of Ranbaxy's forfeiture of its first-filer status, had
    meant that the jury had had no information on what "would have
    8    Of course, as we have now repeated numerous times, the
    plaintiffs voluntarily chose not to pursue the causal mechanism
    involving Teva's at-risk launch after the district court informed
    them that such an argument would trigger jury instructions about
    their need to prove patent invalidity.
    - 66 -
    motivated AstraZeneca to accept an earlier entry date."                 In other
    words, the plaintiffs argue that without evidence on at-risk launch
    or forfeiture, the jury could not appreciate the threat that
    Ranbaxy posed to AstraZeneca or the incentive that AstraZeneca had
    to cut a deal with an earlier entry date.
    However, the jury answered "yes" to Questions 2 and 3 in
    the plaintiffs' favor, despite the supposed exclusion of such
    evidence. Indeed, this exact evidence -- about Ranbaxy's potential
    adverse impact on AstraZeneca's bottom line -- must have, and did,
    come in because the jury in fact found that AstraZeneca felt enough
    of a threat to offer a large and unjustified payment to Ranbaxy
    (Question 2) and offer settlement terms in violation of the
    antitrust laws (Question 3).          The plaintiffs fail to explain what
    other   evidence,     unique     to   Question       4,   the    district   court
    impermissibly excluded to impede the jury's ability to answer that
    question.     To    elaborate,    while    the      plaintiffs    recycle   their
    grievances    about    the     exclusion       of   Leffler's    and   McGuire's
    testimony on the Event Study, possible but-for entry dates, the
    purpose and effect of AstraZeneca's side deals with Ranbaxy, and
    the value of the reverse payment to Ranbaxy, we have already found
    above that all of this evidence was properly excluded. Ultimately,
    the jury had sufficient evidence to answer "yes" to Question 4, as
    well as Questions 2 and 3.        Because the plaintiffs cannot point to
    improperly excluded evidence specific to Question 4, we cannot
    - 67 -
    accept    their   argument     on    the    insufficiency      of     the    evidence
    underlying the jury verdict.
    In light of the jury verdict and other events at trial
    that mooted any summary judgment error, we find no occasion to
    readjudicate the merits of the district court's pretrial decision.
    The plaintiffs are not entitled to set aside the jury verdict.
    V.     CONCLUSION
    In    any   litigation,        each   party     must   make     "tactical
    choices" about what pretrial motions to file, what evidence to
    present, and what objections to renew or forfeit.                     This case was
    no different.     And despite doubts that the district court harbored
    about the merits of the plaintiffs' causation theory even before
    trial    commenced,     the    plaintiffs     were    able    to    present        their
    arguments    to   an    attentive    jury     over    six    weeks.         They    were
    represented by able counsel in every step of the proceeding.
    Having had that opportunity but having failed to convince the jury
    that an antitrust injury occurred, the plaintiffs cannot now rehash
    summary     judgment     and    JMOL       rulings,       scattered     evidentiary
    decisions, and unpreserved objections to the verdict form in search
    of a do-over.
    We affirm.
