    Sohm v. Scholastic Inc.
    United States Court of Appeals
    For the Second Circuit
    August Term 2018

    JOSEPH SOHM, VISIONS OF AMERICA, LLC,
    Plaintiffs-Appellants-Cross-Appellees,
    v.
    SCHOLASTIC INC.,
    Defendant-Appellee-Cross-Appellant.
    Appeal from the United States District Court
    for the Southern District of New York
    No. 16-cv-7098, J. Paul Oetken, Judge.
    Before: POOLER, CHIN, AND SULLIVAN, Circuit Judges.
    Joseph Sohm and Visions of America, LLC sued Scholastic Inc. for copyright
    infringement on photographs Sohm had authored. The district court (J. Paul
    Oetken, J.) granted in part and denied in part the parties’ motions for partial
    summary judgment, determining that Scholastic had infringed Sohm’s copyright
    for six of the photographs, while dismissing all other claims. We affirm in part
    and reverse in part, holding that (1) the district court properly recited the elements
    of a copyright infringement claim and placed the burden of proof on Sohm to
    demonstrate that Scholastic’s use of his images was outside the scope of the
    license; (2) Petrella v. Metro-Goldwyn-Mayer, Inc., 
    572 U.S. 663
    (2014) did not
    abrogate this Circuit’s adoption of the “discovery rule” for copyright infringement
    claim accrual in Psihoyos v. John Wiley & Sons, Inc., 
    748 F.3d 120
    (2d Cir. 2014);
    (3) the Copyright Act limits damages to the three years prior to when a copyright
    infringement action is filed; and (4) the registration of a compilation of
    photographs under 17 U.S.C. § 409 by an applicant who holds the rights to the
    component works is valid and effectively registers the underlying individual
    photos, even if the compilation does not list the individual authors of the
    individual photos.
    AFFIRMED IN PART, REVERSED IN PART.

    RICHARD J. SULLIVAN, Circuit Judge:
    Plaintiffs-Appellants-Cross-Appellees    Joseph   Sohm    and    Visions   of
    America, LLC (together, “Sohm”) bring this action against Defendant-Appellee-
    Cross-Appellant Scholastic Inc. for copyright infringement with respect to 89
    photographs authored by Sohm. The district court (Oetken, J.) granted in part and
    denied in part the parties’ cross motions for partial summary judgment,
    2
    determining that Scholastic had infringed Sohm’s copyright for six of the
    photographs. On appeal, Sohm contends that the district court (1) erred in finding
    that Scholastic’s use of Sohm’s copyrighted work sounded in breach of contract
    and not copyright infringement; (2) improperly shifted the burden of proof to
    Sohm to demonstrate that Scholastic exceeded the scope of its license; and (3)
    incorrectly dismissed Sohm’s claim corresponding to a certain photo. Scholastic
    cross appeals, arguing that the district court erred in (1) holding that the discovery
    rule applies for statute of limitations purposes in determining when Sohm’s claims
    accrued; (2) allowing damages for more than the three years prior to when the
    copyright infringement action was brought; and (3) finding that certain group
    registrations were valid under the Copyright Act for Sohm’s individual
    photographs. We AFFIRM IN PART and REVERSE IN PART.
    I. Background
    Sohm is a professional photographer and the author of the 89 photographs
    at issue in this case. Sohm v. Scholastic Inc., No. 16-cv-7098, 
    2018 WL 1605214
    , at *1
    (S.D.N.Y. Mar. 29, 2018). Scholastic is a publisher and distributor of children’s
    books.
    Id. Sohm entered
    into agreements with agencies, including The Image
    Works, Inc., Continuum Productions Corp. (now Corbis Corp.), and Photo
    3
    Researchers, Inc., to issue limited licenses to third parties on his behalf.
    Id. Those agencies
    issued limited licenses to Scholastic to use Sohm’s photographs and sent
    monthly royalty statements and payments to Sohm.
    Id. In 2004,
    Corbis entered
    into a preferred vendor agreement (“PVA”) with Scholastic that established fees
    for certain print-run ranges of Sohm’s photos.
    Id. In the
    1990s, Sohm participated in Corbis’s copyright registration program.
    Id. Under the
    program, Sohm temporarily assigned his copyrights to Corbis for
    registration purposes, with the understanding that Corbis would reassign the
    copyrights to him after registration.
    Id. Corbis registered
    a number of Sohm’s
    photographs with the Copyright Office as part of several published group
    registrations in its own name.
    Id. at *3.
    None of these group registrations
    identified by name either Sohm or Visions of America as an author.
    Id. In May
    2016, Sohm sued Scholastic for copyright infringement, alleging that
    Scholastic infringed his copyrights by using his photos in various publications in
    numbers exceeding the print runs contemplated in the invoices governing
    Scholastic’s licenses.
    Id. at *2.
    In an amended complaint filed in October 2016, he
    alleged 117 infringing uses of 89 photographs.
    Id. The parties
    each moved for
    partial summary judgment as to certain uses.
    Id. 4 The
    district court granted in part and denied in part the motions. The court
    began by stating the elements of a copyright infringement claim, which it
    formulated as “(i) ownership of a valid copyright; and (ii) unauthorized copying
    of the copyrighted work.”
    Id. (quoting Jorgensen
    v. Epic/Sony Records, 
    351 F.3d 46
    ,
    51 (2d Cir. 2003)). It noted that the existence of a license is treated as an affirmative
    defense, meaning that Scholastic had the burden to prove its existence, but stated
    that “[w]hen the contested issue is the scope of a license, rather than the existence
    of one, the copyright owner bears the burden of proving that the defendant’s
    copying was unauthorized under the license.”
    Id. (quoting Palmer/Kane
    LLC v.
    Rosen Book Works LLC, 
    204 F. Supp. 3d 565
    , 569 (S.D.N.Y. 2016)). Because Sohm’s
    ownership of the copyrights was undisputed, the court found that the case turned
    on the second element: whether Sohm could establish “unauthorized copying.”
    Id.
    The court
    first considered Scholastic’s motion for partial summary
    judgment on the grounds that (1) Sohm’s copyright registrations were invalid for
    certain photographs; (2) Scholastic did not exceed the relevant licenses for certain
    uses; and (3) Sohm had failed to meet his burden to show that Scholastic exceeded
    the license with respect to certain uses.
    Id. at *3.
    Scholastic challenged the validity
    5
    of the copyright registration based on group registration under Corbis’s name,
    asserting that the registrations failed to list the name of the “author” as required
    by 17 U.S.C. § 409(2). The court explained that there is no binding Second Circuit
    authority on the question of whether the registration of a compilation of
    photographs under § 409 by an applicant that holds the rights to the component
    works also effectively registers the underlying individual photos, even if the
    compilation does not list the individual authors of the individual photos.
    Id. at *3–
    6. The court acknowledged that Muench Photography, Inc. v. Houghton Mifflin
    Harcourt Publishing Co., 
    712 F. Supp. 2d 84
    (S.D.N.Y. 2010), concluded that the plain
    language of the Copyright Act, which requires “the name and nationality or
    domicile of the author or authors” to be included in a registration, 17 U.S.C.
    § 409(2), rendered this type of group registration insufficient to constitute
    registration of the individual images therein. Sohm, 
    2018 WL 1605214
    , at *4.
    However, the court noted, the Ninth Circuit reached the opposite conclusion in
    Alaska Stock, LLC v. Houghton Mifflin Harcourt Publishing Co., 
    747 F.3d 673
    (9th Cir.
    2014). Alaska Stock held that if photographers have assigned their copyright to the
    stock agency and the agency registers the collection, “both the collection as a whole
    6
    and the individual images are registered,” even if only the agency’s name is listed
    as an author.
    Id. at 682.
    The district court adopted Alaska Stock’s reasoning, agreeing that the
    operative word in § 409(2) is “work,” not “author.” Sohm, 
    2018 WL 1605214
    , at *4.
    The name of the author of the “work” must be provided, and, in Sohm’s case, the
    author of the collective work – Corbis – was in fact included in the registration.
    The court determined that Muench improperly relied on 17 U.S.C. § 103 in rejecting
    this interpretation, as § 103 deals with the subject matter of copyright rather than
    the conceptually distinct issue of registration.
    Id. The court
    reasoned further that
    Alaska Stock’s interpretation was bolstered by the longstanding practice of the
    Copyright Office and its manuals and opinion letters, which were entitled to
    Skidmore 1 deference – particularly in light of policy considerations such as
    efficiency.
    Id. at *5.
    Because registration of an unpublished collection extends to
    each copyrightable element therein, the court concluded that the valid group
    registration also registered each individual image.
    Id. at *5–6
    (citing 37 C.F.R.
    § 202.3(b)(4) (2018)).
    1   Skidmore v. Swift & Co., 
    323 U.S. 134
    (1944).
    7
    The district court then turned to Scholastic’s claim that there was insufficient
    evidence of unauthorized copying.
    Id. at *8–9.
    For one group of 12 uses, the
    undisputed facts demonstrated that Scholastic did not exceed the print runs under
    the licenses. Sohm maintained that Scholastic could not prove that it did not
    violate the licenses’ geographic limitations, even if it did not exceed their print
    runs, but the court determined that Sohm, not Scholastic, bore the burden on this
    question because the scope, not the existence, of the licenses was in question.
    Id. The court
    therefore granted summary judgment to Scholastic as to these 12 uses.
    Id. at *9.
    For another group of 43 uses, the court found that Sohm had failed to offer
    any evidence that a use occurred at all and thus granted summary judgment to
    Scholastic as to these uses as well.
    Id. As part
    of this group, the court included a
    claim corresponding to Exhibit 5 to the First Amended Complaint, Row 4,
    concerning a photo of a steam engine in Scholastic’s publication Wheels.
    For the final 36 uses, Scholastic contended that Sohm had not satisfied his
    evidentiary burden to prove that the uses were infringing. Sohm did not dispute
    this assertion but attributed the shortcoming to Scholastic’s failure to provide
    invoices and usage information and sought to withdraw the claims without
    8
    prejudice.
    Id. The court
    determined that dismissal without prejudice was
    inappropriate, primarily due to the extent to which suit had progressed and the
    duplicative expense of relitigation. Consequently, the court dismissed the claims
    with prejudice.
    Id. The court
    next considered Sohm’s motion for partial summary judgment
    based on 13 uses Scholastic did not dispute exceeded the authorized print run.
    Id. at *10.
    Scholastic averred that it could not be held liable for infringement as to
    these uses because (1) Sohm’s claims are barred by the Copyright Act’s limitations
    provision; (2) Sohm’s damages should be limited to those incurred within the
    three years before commencement of the suit; and (3) under Scholastic’s PVAs
    with Corbis, the relevant print-run limitations were contractual covenants, not
    conditions precedent, meaning that the claims for exceeding the limitations
    sounded in breach of contract, which was not pleaded by Sohm, rather than
    copyright infringement.
    Id. at *10–14.
    Considering Scholastic’s statute of limitations claim first, the court applied
    the discovery rule and rejected Scholastic’s assertion that Sohm, with due
    diligence, should have discovered the infringing acts more than three years prior
    to when he brought suit.
    Id. at *10–11.
    The court concluded that Scholastic had
    9
    failed to identify affirmative evidence of any information that could have
    prompted an inquiry by Sohm.
    Id. at *11.
    Second, the court found Scholastic’s contention that damages should be
    limited to the three years prior to the suit irrespective of the statute of limitations
    unavailing.
    Id. The court
    noted that the issue has split district courts in this Circuit
    post Petrella v. Metro-Goldwyn-Mayer, Inc., 
    572 U.S. 663
    (2014), but ultimately
    reasoned that Psihoyos v. John Wiley & Sons, Inc., 
    748 F.3d 120
    (2d Cir. 2014),
    remained good law and that Petrella should not be read to establish a time limit on
    the recovery of damages distinct from the statute of limitations. Sohm, 
    2018 WL 1605214
    , at *11.
    Third, the district court analyzed Scholastic’s assertion that the print-run
    limitations in its Corbis licenses were covenants, rather than conditions.
    Id. at *12–
    14. Applying New York law, the court found that the payment terms in Corbis’s
    PVAs with Scholastic did not contain sufficiently unmistakable language to give
    rise to a condition precedent and were therefore contractual covenants.
    Id. at *13.
    Sohm’s claims therefore sounded in breach of contract, which he had not pleaded.
    Accordingly, the court granted summary judgment to Scholastic on these claims.
    Id. at *14.
    10
    The district court last considered Sohm’s claims as to images licensed by
    Photo Researchers and Image Works, found that Scholastic had not raised a
    genuine dispute of fact as to whether it had infringed those copyrights, and
    granted summary judgment to Sohm.
    Id. at *14.
    The parties settled the remaining claims, which were scheduled for trial, but
    they reserved their rights to appeal aspects of the district court’s summary
    judgment rulings.
    II. Discussion
    On appeal and cross-appeal, Sohm and Scholastic each raise three
    challenges to the district court’s summary judgment. Sohm contends that the
    district court erred by (1) “finding, with respect to images Scholastic obtained from
    Corbis, that Sohm can sue only for breach of contract and not copyright
    infringement” because the print-run limitations were conditions precedent, not
    contractual covenants, Sohm’s Br. at 15; (2) shifting the burden of proof to Sohm
    to demonstrate that Scholastic exceeded the scope of its license; and (3) incorrectly
    dismissing “Sohm’s claim corresponding to Row 4 of Exhibit 5 to the First
    Amended Complaint,”
    id. at 36–37.
    Scholastic maintains that the district court
    erred when it (1) applied the “discovery rule,” not the “injury rule,” to determine
    11
    when Sohm’s claims accrued for statute of limitations purposes, Scholastic’s Br. at
    33–35; (2) allowed damages for more than the three years prior to when the
    copyright infringement suit was filed; and (3) determined that Corbis’s group
    registrations, which did not indicate that Sohm or Visions of America was the
    author of any included photographs, were valid under the Copyright Act for
    Sohm’s individual photographs.
    “We review de novo the [d]istrict [c]ourt’s partial grant and partial denial of
    summary judgment.” 
    Psihoyos, 748 F.3d at 123
    .
    A. Sohm’s Arguments on Appeal
    1. The District Court Misconstrued Sohm’s Claims as Contract Claims Rather
    Than Copyright Infringement Claims
    Sohm alleged that Scholastic committed copyright infringement by
    exceeding the print-run limitations contained in the license documents. The
    district court, however, found that the license provisions were contractual
    covenants, and thus that his claims sounded only in breach of contract. Sohm
    maintains that the court “erred in its condition / covenant analysis, ignoring clear
    language of condition in the [license] documents.” Sohm’s Br. at 13. He contends
    that the district court misconstrued unmistakable language of conditions
    12
    precedent, and therefore that he properly brought claims sounding in copyright
    infringement, not breach of contract. We agree.
    “Generally, ‘if the licensee’s improper conduct constitutes a breach of a
    covenant undertaken by the licensee and if such covenant constitutes an
    enforceable contractual obligation, then the licensor will have a cause of action for
    breach of contract,’ not copyright infringement.” Graham v. James, 
    144 F.3d 229
    ,
    236 (2d Cir. 1998) (brackets and alteration omitted) (quoting 3 Melville B. Nimmer
    & David Nimmer, Nimmer on Copyright § 10.15[A]). “However, ‘if the nature of a
    licensee’s violation consists of a failure to satisfy a condition to the license, it
    follows that the rights dependent upon satisfaction of such condition have not
    been effectively licensed, and therefore, any use by the licensee is without
    authority from the licensor and may therefore, constitute an infringement of
    copyright.’”
    Id. at 237
    (brackets and alteration omitted) (quoting 3 Nimmer on
    Copyright § 10.15[A]).
    Under New York law, a covenant is “a manifestation of intention to act or
    refrain from acting in a specified way, so made as to justify a promise in
    understanding that a commitment has been made.” Merritt Hill Vineyards Inc. v.
    Windy Heights Vineyard, Inc., 
    61 N.Y.2d 106
    , 112 (1984) (citation omitted). A
    13
    condition precedent, on the other hand, is “an act or event . . . which, unless the
    condition is excused, must occur before a duty to perform a promise in the
    agreement arises.” Oppenheimer & Co. v. Oppenheim, Appel, Dixon & Co., 
    86 N.Y.2d 685
    , 690 (1995) (citation omitted). “New York respects a presumption that terms
    of a contract are covenants rather than conditions,” 
    Graham, 144 F.3d at 237
    , and
    “[c]onditions precedent are not readily assumed,” Bank of N.Y. Mellon Tr. Co. v.
    Morgan Stanley Mortg. Capital, Inc., 
    821 F.3d 297
    , 305 (2d Cir. 2016). Nevertheless,
    though conditions precedent must be “expressed in unmistakable language,”
    id. at 305
    (quoting 
    Oppenheimer, 86 N.Y.2d at 691
    ), “specific, talismanic words are not
    required,”
    id. “[L]inguistic conventions
    of condition—such as ‘if,’ ‘on condition
    that,’ ‘provided that,’ ‘in the event that,’ and ‘subject to[]’”—can “make plain” a
    condition precedent.
    Id. at 305–06.
    “It is . . . for the court to decide, as a matter of
    law, whether a condition precedent . . . exists under the terms of a contract.”
    Powlus v. Chelsey Direct, LLC, No. 09-cv-10461, 
    2011 WL 135822
    , at *4 (S.D.N.Y. Jan.
    10, 2011).
    “[I]f ‘a license is limited in scope and the licensee acts outside the scope, the
    licensor can bring an action for copyright infringement.’” BroadVision, Inc. v. Med.
    14
    Protective Co., No. 08-cv-1478, 
    2010 WL 5158129
    , at *3 (S.D.N.Y. Nov. 23, 2010)
    (quoting Jacobsen v. Katzer, 
    535 F.3d 1373
    , 1380 (Fed. Cir. 2008)).
    Here, the PVAs, invoices, and documents incorporated therein constitute
    the license agreements between Scholastic and Corbis. See App’x at 164 (“Along
    with the Corbis invoice, these terms constitute a binding agreement (‘Agreement’)
    between you and Corbis Corporation.”);
    id. at 176
    (“‘Agreement’ means,
    collectively, the terms and conditions (i) herein, (ii) in the Invoice(s) and (iii) in the
    Specific Content Web Page(s) applicable to the Content licensed hereunder, all of
    which are incorporated into this Agreement by this reference.”).
    These license agreements granting Scholastic the right to copy Sohm’s
    photos contain unmistakable language of conditions precedent, and therefore
    Sohm properly pleaded claims of copyright infringement.                The Terms and
    Conditions incorporated into and attached to the 2004 PVA state that “[a]ny
    license granted by Corbis is conditioned upon (i) your meeting all conditions and
    restrictions imposed by Corbis, and (ii) Corbis’ receipt of full payment by you for
    such use as invoiced by Corbis.”
    Id. at 164.
    The Terms further state that “[u]nless
    otherwise specified in a separate writing signed by Corbis, your reproduction of
    Images is limited to (i) internal evaluation or comps, or (ii) the specific use
    15
    described in your invoice, which together with these terms shall constitute the full
    license granted.”
    Id. The Terms
    also explain that “[e]xcept as specified in the
    Corbis invoice, Images obtained from Corbis are licensed on a non-transferable,
    one-time, non-exclusive basis, and are strictly limited to the use, medium, time
    period, print run, placement, size of image, territory, and any other restrictions
    indicated in the invoice.”
    Id. The invoices,
    in turn, specified the quantity and uses
    that were licensed.    E.g.,
    id. at 127.
      The Terms also explicitly warned that
    “[u]nauthorized use of these Images constitutes copyright infringement and shall
    entitle Corbis to exercise all rights and remedies under applicable copyright law.”
    Id. at 164.
    The Terms and Conditions incorporated into and attached to the 2008 PVA
    contain similar language, stating that “[a]ny and all licenses granted by Corbis are
    conditioned upon (i) Your compliance with all provisions of this Agreement, and
    (ii) Corbis’ receipt of full payment by You as identified in the applicable invoice.”
    Id. at 175.
    The Terms also state that “[e]xcept where specifically permitted on the
    Invoice for the applicable Content, You may not distribute, publish, display, or
    otherwise use in any way, the Rights Managed Content.”
    Id. 16 These
    provisions are replete with the conditional language of conditions
    precedent – “unless,” “conditioned upon,” “except where specifically permitted”
    – thereby directly refuting the conclusion that the license agreements created only
    contractual covenants, the violation of which sounds in breach of contract. Sohm
    asserts that Scholastic exceeded print-run limitations contained in the invoices
    forming part of the license agreements, and thus he properly pleads that Scholastic
    has violated a restriction upon which the license is conditioned.
    We are not alone in reaching this conclusion. In Kashi v. McGraw-Hill Global
    Education Holdings, No. 17-cv-1818, 
    2018 WL 5262733
    (E.D. Pa. Oct. 23, 2018), the
    district court, interpreting similar license agreements to those at issue here and
    applying New York law, reasoned that “the language of [the PVAs], along with
    the invoices, create[s] a condition in unmistakable terms,”
    id. at *5.
    “[T]hus, by
    exceeding the uses authorized by the invoices, Defendants violated a condition of
    their license agreements with Corbis,” thereby entitling plaintiff to assert
    copyright infringement claims.
    Id. Rejecting an
    interpretation of the license
    agreements that would render provisions mere delineations of acceptable and
    unacceptable behavior, the court found that such an analysis would render it
    “virtually impossible to limit the scope of the license.”
    Id. at *6.
    Rather, the license
    17
    agreements’ language “clearly stated that authorization to use a photo was
    conditioned upon an invoice granting permissions and upon receipt of payment,”
    and thus “put unauthorized use in excess of the quantities permitted by the
    invoices beyond the scope of the Agreements.”
    Id. Overuse of
    the photos,
    therefore, “implicates a condition, not a covenant, and . . . any alleged breaches
    sound in copyright infringement, not breach of contract.”
    Id. at *7.
    Numerous other courts have agreed when confronted with similar
    circumstances. See, e.g., Menzel v. Scholastic, Inc., No. 17-cv-5499, 
    2019 WL 6896145
    ,
    at *7–9 (N.D. Cal. Dec. 18, 2019); Krist v. Pearson Educ., Inc., No. 16-cv-6178, 
    2019 WL 6467355
    , at *5–8 (E.D. Pa. Dec. 2, 2019); Krist v. Scholastic, Inc., 
    415 F. Supp. 3d 514
    , 533–36 (E.D. Pa. 2019); Harrington v. McGraw-Hill Glob. Educ. Holdings, LLC,
    No. 17-cv-2960, 
    2019 WL 1317752
    (D. Colo. Mar. 22, 2019); Pac. Stock, Inc. v. Pearson
    Educ., Inc., 
    927 F. Supp. 2d 991
    (D. Haw. 2013). In Harrington, the district court
    interpreted substantially identical Corbis agreements to those at issue here and
    agreed with the Kashi court that “the parties’ agreement expressly provided that
    unauthorized use of the images would constitute copyright infringement,” and
    that use in excess of the print-run limitations was unauthorized use. 
    2019 WL 1317752
    , at *3. The court emphasized the same language in the parties’ agreements
    18
    and rejected course of conduct evidence as insufficient to convert the case from
    one of copyright infringement to one of breach of contract.
    Id. In Pacific
    Stock, the
    court reached a similar conclusion, finding that print-run limitations in the context
    of a comparable PVA scheme “define the scope of the license; they are not simply
    covenants enforceable only through a breach of contract 
    action.” 927 F. Supp. 2d at 998
    .
    We conclude that the language is clear on the face of the license agreements:
    the print-run limitations were conditions precedent, the violation of which gave
    rise to claims for copyright infringement. Sohm thus properly pleaded copyright
    infringement. Accordingly, we reverse the grant of partial summary judgment to
    Scholastic on this basis.
    2. The District Court Properly Applied the Elements of Copyright Infringement
    to Sohm’s Claims
    Sohm next contends that the district court (1) misstated the elements of a
    claim for copyright infringement and (2) misallocated to Sohm the burden of
    proving that Scholastic’s use fell outside the scope of the license. He first maintains
    that the court’s version of the elements of a prima facie case – “(i) ownership of a
    valid copyright; and (ii) unauthorized copying of the copyrighted work,” Sohm,
    
    2018 WL 1605214
    , at *2 – erroneously included the term “unauthorized.” Instead,
    19
    Sohm urges that the proper formulation of the second element is “copying of
    constituent elements of the work that are original.” Sohm’s Br. at 40 (quoting Feist
    Publ’ns, Inc. v. Rural Tel. Serv. Co., 
    499 U.S. 340
    , 361 (1991)).
    He further asserts that the district court’s version of the elements of a
    copyright infringement case as applied in a license case, as opposed to a
    substantial similarity case, created an “impossible burden” in light of Scholastic’s
    claim that “it retained no records of its original licensing.”
    Id. at 41.
    According to
    Sohm, it was inappropriate to place on him the burden of showing that Scholastic’s
    use exceeded its license because there was “no legitimate scope of license issue”
    where Scholastic exceeded the print runs on the face of the invoices.
    Id. at 42.
    He
    argues that Scholastic “ha[d] the burden of coming forward with proof that it had
    a license for the uses at issue.”
    Id. at 43.
    Sohm’s arguments on these points fail.               The district court neither
    erroneously misstated the elements of a claim for copyright infringement nor
    improperly shifted the burden of proof to Sohm to demonstrate that Scholastic
    exceeded the scope of its license. We therefore affirm.
    “In a copyright infringement case, the plaintiff must show: (i) ownership of
    a valid copyright; and (ii) unauthorized copying of the copyrighted work.”
    20
    
    Jorgensen, 351 F.3d at 51
    . The existence of a license to engage in the challenged
    copying, however, is “an affirmative defense to a claim of copyright
    infringement . . . that the alleged infringer must plead and prove.” Yamashita v.
    Scholastic Inc., 
    936 F.3d 98
    , 104 (2d Cir. 2019); see also Bourne v. Walt Disney Co., 
    68 F.3d 621
    , 630–31 (2d Cir. 1995). Nevertheless, “when the contested issue is the
    scope of a license, rather than the existence of one, the copyright owner bears the
    burden of proving that the defendant’s copying was unauthorized under the
    license and the license need not be pleaded as an affirmative defense.” 
    Graham, 144 F.3d at 236
    ; see also 
    Yamashita, 936 F.3d at 105
    (“Applying these principles in
    the context of initial pleadings, when the existence of a license is not in question, a
    copyright holder must plausibly allege that the defendant exceeded the particular
    terms of the license.”).
    Here, the district court’s recitation of the elements of a copyright
    infringement claim was correct in both form and substance.                 As Graham
    demonstrates, in cases involving licenses, we have interpreted “unauthorized” use
    to mean use outside of the 
    license. 144 F.3d at 236
    (requiring copyright holder to
    demonstrate that “defendant’s copying was unauthorized under the license”);
    
    Bourne, 68 F.3d at 631
    .
    21
    In addition, the district court properly required Sohm to demonstrate use
    outside the scope of the license. Because Sohm pleaded in his complaint that
    licenses exist – a fact that Scholastic admits – Sohm bore the burden of proving
    that Scholastic’s copying was unauthorized, a burden he failed to satisfy. Sohm’s
    attempts to avoid this burden by recasting the relevant inquiry as one of the
    existence of a license or of the proper formulation of the elements of a copyright
    infringement claim are unavailing in the face of these clear principles. The district
    court properly framed the question as whether Scholastic had exceeded the scope
    of existing licenses, and therefore properly placed the burden of demonstrating
    unauthorized copying on Sohm. Accordingly, the court did not err in reciting the
    elements of a copyright infringement claim nor in requiring Sohm to demonstrate
    use outside the scope of the license.
    3. Sohm Offered Sufficient Proof of Infringement to Survive Summary
    Judgment on the Steam Engine Photo
    Sohm avers that the district court erroneously granted partial summary
    judgment to Scholastic on his claim at Row 4 of Exhibit 5 to the First Amended
    Complaint, concerning a photo of a steam engine in Scholastic’s publication
    Wheels. We agree.
    22
    Sohm proffered evidence that Scholastic obtained a limited license from The
    Image Works to print 40,000 copies of Sohm’s image in Wheels, but actually printed
    195,500 copies. Scholastic did not dispute this evidence nor include this claim in
    the group of claims for which it sought summary judgment on the basis that the
    evidence did not show infringement. Consequently, the district court’s dismissal
    of this claim appears to have been inadvertent. Scholastic “agrees that it did not
    seek dismissal of this claim under any theory agreed with by the District Court,”
    and thus does not oppose Sohm’s request that this dismissal be reversed.
    Scholastic’s Br. at 3 n.1. Accordingly, we reverse the district court’s grant of partial
    summary judgment to Scholastic on Sohm’s claim of copyright infringement
    corresponding to the image at Row 4 of Exhibit 5 to the First Amended Complaint.
    B. Scholastic’s Cross-Appeal
    As noted above, Scholastic argues in its cross-appeal that the district court
    erred when it (1) applied the “discovery rule,” not the “injury rule,” to determine
    when Sohm’s claims accrued for statute of limitations purposes,
    id. at 33–35;
    (2)
    allowed damages for more than the three years prior to when the copyright
    infringement suit was filed; and (3) determined that Corbis’s group registrations,
    which did not indicate that Sohm or Visions of America was the author of any
    23
    included photographs, were valid under the Copyright Act for Sohm’s individual
    photographs. We will address each of these contentions in turn.
    1. The District Court Properly Applied the Discovery Rule in Determining
    When Sohm’s Copyright Claims Accrued
    In Psihoyos, this Court adopted the “discovery rule” for determining when
    a copyright infringement claim 
    accrues. 748 F.3d at 124
    –25.        Scholastic
    nevertheless urges this Court to adopt the “injury rule” instead, maintaining that
    “in two recent decisions following Psihoyos, the Supreme Court cast serious doubt
    on the viability of the discovery rule.” Scholastic’s Br. at 34 (citing SCA Hygiene
    Prods. Aktiebolag v. First Quality Baby Prods., LLC, 
    137 S. Ct. 954
    (2017); Petrella, 
    572 U.S. 663
    ). We disagree and decline to alter this Circuit’s precedent mandating use
    of the discovery rule; we therefore affirm the district court’s holding that the
    discovery rule applies for statute of limitations purposes in determining when a
    copyright infringement claim accrues under the Copyright Act.
    “Civil actions for copyright infringement must be ‘commenced within three
    years after the claim accrued.’” 
    Psihoyos, 748 F.3d at 124
    (quoting 17 U.S.C.
    § 507(b)). As we noted in Psihoyos, we apply “a discovery rule for copyright claims
    under 17 U.S.C. § 507(b).”
    Id. Under that
    rule, “an infringement claim does not
    24
    ‘accrue’ until the copyright holder discovers, or with due diligence should have
    discovered, the infringement.”
    Id. Psihoyos, as
    a published opinion of a prior panel, is binding precedent upon
    this Court “unless and until its rationale is overruled, implicitly or expressly, by
    the Supreme Court or this court en banc.” United States v. Allah, 
    130 F.3d 33
    , 38 (2d
    Cir. 1997) (quoting United States v. Ianniello, 
    808 F.3d 184
    , 190 (2d Cir. 1986)).
    Scholastic contends that the Supreme Court has done just that, first in Petrella and
    subsequently in SCA Hygiene Products. The Supreme Court, however, has not
    overruled Psihoyos, either implicitly or explicitly, and therefore we must continue
    to apply the discovery rule.
    Petrella specifically noted that it was not passing on the question of the
    discovery rule. 
    See 572 U.S. at 670
    n.4. The Supreme Court reaffirmed that position
    in SCA Hygiene Products, explaining that it had “specifically noted” in Petrella that
    it had “not passed on the question whether the Copyright Act’s statute of
    limitations is governed by such a 
    rule.” 137 S. Ct. at 962
    (internal quotation marks
    and citation omitted). Consequently, while some language in Petrella is perhaps
    consistent with the injury rule, in light of the Supreme Court’s direct and repeated
    representations that it has not opined on the propriety of the discovery or injury
    25
    rules, it would contravene settled principles of stare decisis for this Court to depart
    from its prior holding in Psihoyos on the basis of Petrella. 2
    Given the continuing propriety of the discovery rule in this Circuit, we must
    now determine whether the district court properly applied that rule, namely,
    whether the court erred in finding that Sohm did not discover, nor with due
    diligence should have discovered, Scholastic’s purported copyright infringements
    more than three years prior to when he filed suit. Scholastic contends that even
    under the discovery rule standard, Sohm’s claims accrued more than three years
    prior to his filing suit, thereby falling outside the Copyright Act’s statute of
    limitations and barring his claims. We find, however, that the district court did
    not err in rejecting these contentions and in finding that Scholastic had “failed to
    meet its evidentiary burden to survive summary judgment on” statute of
    limitations grounds. Sohm, 
    2018 WL 1605214
    , at *11.
    2Contrary to Scholastic’s contentions, the Supreme Court’s recent decision in Rotkiske v. Klemm, 
    140 S. Ct. 355
    (2019), does not persuade us to depart from this holding. In Rotkiske, the Supreme Court held that the
    statute of limitations of the Fair Debt Collection Practices Act (“FDCPA”), which states that an action may
    be brought under the FDCPA “within one year from the date on which the violation occurs,” 15 U.S.C.
    § 1692k(d), “begins to run on the date on which the alleged . . . violation occurs, not the date on which the
    violation is discovered,” 
    Rotkiske, 140 S. Ct. at 358
    . Rotkiske’s holding, however, was based on the Court’s
    interpretation of the FDCPA’s text; the decision did not interpret the Copyright Act’s statute of limitations,
    which states that copyright infringement claims under the Act must be “commenced within three years
    after the claim accrued.” 17 U.S.C. § 507(b). Accordingly, Rotkiske is inapposite here.
    26
    The district court determined that Scholastic had failed to “identify some
    affirmative evidence that would have been sufficient to awaken inquiry and
    prompt an audit” on Sohm’s part for him to have discovered the copyright
    infringements earlier.
    Id. (internal quotation
    marks and citation omitted).
    Scholastic merely maintains that Sohm never conducted an audit or contacted his
    agents to inquire about payments despite having the ability to do so. Nevertheless,
    without identifying facts or circumstances that would have prompted such an
    inquiry, Scholastic cannot rely on the passage of time alone to establish that Sohm
    should have discovered the alleged copyright infringements at issue in this case.
    Scholastic has therefore not demonstrated that Sohm’s claims accrued outside the
    Copyright Act’s statute of limitations. Accordingly, the district court properly
    rejected Scholastic’s affirmative defense based on the Copyright Act’s statute of
    limitations.
    2. The Copyright Act Limits Sohm’s Damages to the Three Years Prior to the
    Commencement of This Action
    Scholastic next argues that even if the district court was correct to apply the
    discovery rule, it erred in allowing Sohm to recover damages for more than three
    years prior to when he filed his copyright infringement suit. Again pointing to
    Petrella, Scholastic maintains that “[t]he Supreme Court was crystal clear . . . that,
    27
    independent of whether the injury or discovery rule applies, ‘[u]nder the
    [Copyright] Act’s three-year provision, an infringement is actionable within three
    years, and only three years, of its occurrence,’ and that ‘the infringer is insulated
    from liability for earlier infringements of the same work.’” Scholastic’s Br. at 38–
    39 (quoting 
    Petrella, 572 U.S. at 671
    ).
    On this point, we agree with Scholastic.         Despite not passing on the
    propriety of the discovery rule in Petrella, the Supreme Court explicitly delimited
    damages to the three years prior to the commencement of a copyright
    infringement action.      Accordingly, we reverse the district court’s contrary
    determination.
    After Petrella, district courts in this Circuit have reached conflicting
    determinations regarding whether damages under the Copyright Act are limited
    to three years prior to when a copyright infringement case is filed. Compare Park
    v. Skidmore, Owings & Merrill LLP, No. 17-cv-4473, slip op. at 5 (S.D.N.Y. Sept. 30,
    2019) (“[T]he Copyright Act provides for a three-year lookback period – a plaintiff
    can bring a suit for any infringing actions in the three years before the filing date,
    but cannot recover damages for infringements occurring more than three years
    before filing.”), Papazian v. Sony Music Entm’t, No. 16-cv-7911, 
    2017 WL 4339662
    ,
    28
    at *5 (S.D.N.Y. Sept. 28, 2017) (“[B]ecause the clear and specific three-year
    limitation on damages under section 507(b) was necessary to the result in Petrella,
    it cannot be construed as dicta.”), Fischer v. Forrest, No. 14-cv-1304, 
    2017 WL 128705
    , at *7 (S.D.N.Y. Jan. 13, 2017), report and recommendation adopted, 
    2017 WL 1063464
    (S.D.N.Y. Mar. 21, 2017), and Wu v. John Wiley & Sons, Inc., No. 14-cv-6746,
    
    2015 WL 5254885
    , at *7 (S.D.N.Y. Sept. 10, 2015) (“Following Petrella, Wu can
    recover damages only for any Wiley infringing acts that occurred [not more than
    three years prior to filing the action].”), with Energy Intelligence Grp., Inc. v. Scotia
    Capital (USA) Inc., 16-cv-617, 
    2017 WL 432805
    , at *2 (S.D.N.Y. Jan. 30, 2017)
    (“[U]nder no reasonable reading of Petrella could the opinion be interpreted to
    establish a time limit on the recovery of damages separate and apart from the
    statute of limitations.”). Agreeing with the former decisions, we determine that
    Petrella’s plain language explicitly dissociated the Copyright Act’s statute of
    limitations from its time limit on damages.
    In Petrella, the Supreme Court initiated its examination of the Copyright
    Act’s statute of limitations by explaining that “[u]nder the Act’s three-year
    provision, an infringement is actionable within three years, and only three years,
    of its occurrence” and that “the infringer is insulated from liability for earlier
    29
    infringements of the same 
    work.” 572 U.S. at 671
    . It stated that “§ 507(b)’s
    limitations period . . . allows plaintiffs . . . to gain retrospective relief running only
    three years back from the date the complaint was filed.”
    Id. at 672.
    It also explicitly
    asserted that “a successful plaintiff can gain retrospective relief only three years
    back from the time of suit” and that “[n]o recovery may be had for infringement
    in earlier years.”
    Id. at 677.
    Thus, damages “outside the three-year window”
    before Petrella filed suit could not be recovered.
    Id. Consequently, Petrella
    and
    Psihoyos counsel that we must apply the discover rule to determine when a
    copyright infringement claim accrues, but a three-year lookback period from the
    time a suit is filed to determine the extent of the relief available.
    Resisting this interpretation of Petrella, Sohm contends that the language
    from Petrella on which it relies was merely nonprecedential “dicta, taken out of
    context.” Sohm Reply Br. at 29. Not so. We are bound “not only [by] the result
    [of a Supreme Court opinion,] but also those portions of the opinion necessary to
    that result.” Seminole Tribe of Fla. v. Florida, 
    517 U.S. 44
    , 67 (1996). The Petrella
    Court partially based its determination that laches was inapplicable to actions
    under the Copyright Act on the conclusion that the statute “itself takes account of
    delay” by limiting damages to the three years prior to when suit is filed. Petrella,
    
    30 572 U.S. at 677
    . Therefore, the three-year limitation on damages was necessary to
    the result in Petrella and thus binding precedent.
    Accordingly, under the Copyright Act, a plaintiff’s recovery is limited to
    damages incurred during the three years prior to filing suit. We reverse the district
    court’s contrary conclusion.
    3. Corbis Validly Registered Each of Sohm’s Photographs
    Scholastic finally argues that Sohm’s copyright infringement claims based
    on Corbis’s group copyright registrations, which did not include Sohm’s name as
    an author, are invalid. Citing to Muench, Scholastic asserts that Sohm’s name was
    required to be included in the group registrations for them to be valid under the
    Copyright 
    Act, 712 F. Supp. 2d at 85
    , thereby rejecting the district court’s contrary
    conclusion here and the Ninth Circuit’s contrary conclusion in Alaska Stock. We,
    however, agree with the district court and the Ninth Circuit. The “author” that
    must be identified in a group registration under 17 U.S.C. § 409(2) is the author of
    the compilation, rather than the author of each underlying work, and a valid group
    registration works to register each individual work included in the compilation.
    A certificate of copyright registration is a prerequisite to asserting a civil
    copyright infringement claim. 17 U.S.C. § 411(a). Thus, without a valid copyright
    31
    registration, a plaintiff cannot bring a viable copyright infringement action. The
    Copyright Act requires that an “application for copyright registration shall be
    made on a form prescribed by the Register of Copyrights and shall include . . . the
    name . . . of the author or authors [of the work].”
    Id. § 409(2).
    We must decide whether the registration of a compilation of photographs
    under § 409 by an applicant that holds the rights to the component works also
    effectively registers the underlying individual photos where the compilation does
    not list the individual authors of the individual photos. Our Court has yet to
    address this question, and the courts that have addressed it have arrived at
    conflicting conclusions. For example, in Muench, the district court concluded that
    interpreting the Copyright Act to allow group registrations to register the
    individual photographs contained therein, where the group registrations do not
    include the name of the authors of the individual photographs, contravened the
    Act’s plain 
    language. 712 F. Supp. 2d at 92
    . However, in Alaska Stock, the Ninth
    Circuit reached the opposite conclusion, holding that if “the photographers have
    assigned their ownership of their copyrights in their images to the stock agency,
    and the stock agency registers the collection, both the collection as a whole and the
    individual images are 
    registered.” 747 F.3d at 682
    .
    32
    We agree with the district court below and the Ninth Circuit. The plain
    language of § 409(2) does not require a group registrant like Corbis to include each
    individual author of each individual work in the compilation to effectively register
    those individual works. The key word in § 409(2) is “work” instead of “author.”
    As the Ninth Circuit explained, “[t]his subsection says that the name of the author
    or authors of ‘the work’ must be provided, the statute defines a ‘collective work’
    as being a type of ‘work,’ and here, the author of the collective work was” Corbis.
    Alaska Stock, 
    747 F.3d 681
    (footnote omitted). Consequently, to obtain a valid
    group registration under § 409(2), “[t]he ‘author or authors’ that must be
    listed . . . are the author or authors of the collective work itself.” 3
    Id. The Corbis
    group registrations all satisfied this requirement by listing Corbis as the author of
    the collective work.
    Accordingly, the district court properly determined that Corbis validly
    registered each of the photographs in the relevant group registrations.
    3The Ninth Circuit reaffirmed Alaska Stock in Unicolors, Inc. v. Urban Outfitters, Inc., 
    853 F.3d 980
    ,
    989 (9th Cir. 2017).
    33
    III. Conclusion
    For the foregoing reasons, we AFFIRM the district court’s (1) recitation of
    the elements of a copyright infringement claim and its placement of the burden of
    proof on Sohm to demonstrate Scholastic’s use of his images outside the scope of
    the license; (2) conclusion that the discovery rule applies for statute of limitations
    purposes in determining when Sohm’s copyright infringement claims accrued;
    and (3) determination that Corbis’s group registrations were valid under the
    Copyright Act for Sohm’s individual photographs. We REVERSE the district
    court’s (1) finding that Scholastic’s use of Sohm’s copyrighted work sounded in
    breach of contract and not copyright infringement; (2) dismissal of Sohm’s claim
    corresponding to Row 4 of Exhibit 5 to the First Amended Complaint; and
    (3) allowance of damages for more than the three years prior to when Sohm filed
    his copyright infringement action. We further REMAND to the district court for
    proceedings consistent with this opinion.
    34
