The question presented, one of first impression in the courts of appeals, is whether an action for infringement by one coauthor of a song can be defeated by a “retroactive” transfer of copyright ownership from another co-author to an alleged infringer. This action arises under the current statute governing copyright law, the Copyright Act of 1976, 17 U.S.C. §§ 101
et seq.
(“the Copyright Act”), because “the complaint is [in part] for a remedy expressly granted by [the Copyright Act], e.g., a suit for infringement ..., [and] asserts a claim requiring construction of [the Copyright Act], ... or, at the very least ... presents a case where a distinctive policy of [the Copyright Act] requires that federal principles control the disposition of the claim.”
T.B. Harms Co. v. Eliscu,
Plaintiff Sharice Davis (“plaintiff’ or “Davis”) appeals from an order of the United States District Court for the Southern District of New York (Charles S. Haight, Jr.,
Judge)
dismissing by summary judgment her claims under the Copyright Act, her claim for a declaratory judgment under 28 U.S.C. § 2201, and her state-law claims alleging unfair competition, unjust enrichment, and violations of New York’s consumer protection statutes.
See Davis v. Blige,
*94 We disagree, and therefore vacate the judgment and remand for further proceedings consistent with this opinion.
BACKGROUND
A. Facts
The facts of this case are laid out fully in Judge Haight’s opinion. We recount here only those facts relevant to the issues on appeal. Unless otherwise noted, the facts are undisputed.
The dispute between the parties arises from the release in 2001 of an album entitled “No More Drama” (“the Album”). Defendant Mary J. Blige, the “Queen of Hip-Hop Soul,” J.A. 325, was the performer on the Album, which achieved “triple platinum” status. 2 Davis alleges that two of the songs contained on the Album— “LOVE” and “Keep It Moving” (collectively, the “Album compositions”) — infringe her copyright in two compositions (collectively, the “disputed compositions”). In particular, she claims that “LOVE” is virtually identical to her composition “L.O.V.E.,” and that “Keep It Moving” bears substantial similarity to her composition “Don’t Trade in My Love.” Davis does not receive any song-writing credit on the Album; instead, the labels and packaging of the Album identify (1) Blige, Miller, and defendants Kwame Holland and Ronald Lawrence as the authors of “LOVE” and (2) Blige, Miller, Holland, and defendant Dana Stinson as the authors of “Keep It Moving.” See id. at 495 n. 2.
Davis claims the disputed compositions were co-authored in 1998 by her and Chambliss, Miller’s father; Chambliss is not a party to this action. According to one witness, Hunter College Professor Bаrbara Ottaviani, the disputed composition “L.O.V.E.” was written in 1998 during jam sessions in the home of Ottaviani attended by, among others, Davis, Cham-bliss, and Miller. A tape recording of “L.O.V.E.” was made during one of these jam sessions, but the tape disappeared shortly thereafter. At about this time Davis met Blige, who is Miller’s sister and the step-daughter of Chambliss. Davis states that she had performed “L.O.V.E.” for Blige and that Miller subsequently approached Davis on behalf of Blige, seeking to buy several of Davis’s songs, including “L.O.V.E.” Davis alleges that she declined the offer. She also alleges that she wrote “Don’t Trade in My Love” with Chambliss in or around November 1998 at Ruff Riders Studio.
In August 2001, defendants Ausar Music, Mary J. Blige Publishing, Bruce Miller Publishing, and Kwame Holland Publishing registered “LOVE” and defendant Universal Music MCA Music Publishing, and Blige, Miller, and Stinson registered “Keep It Moving” with the United States Copyright Office (“Copyright Office”). On February 28, 2002, Miller contracted with Universal Tunes, a division of defendant Universal, Inc., to provide an exclusive license to exploit his copyright interest in the Album compositions as well as his copyright interests in any other compositions not previously assigned to other music publishing companies. On August 14, 2002, Davis registered the disputed compositions with the Copyright Office, listing Chambliss as a co-author. In December 2003, Davis filed suit, alleging infringement of her copyright in the two disputed *95 compositions and a variety of related state claims.
Defendants’ April 30, 2003 and August 11, 2003 answers to Davis’s complaint denied that anyone other than the defendants listed as authors on the Album wrote the songs. But in depositions given in December 2003 and January 2004 (Miller), and June and August 2004 (Chambliss), both Miller and Chambliss testified that
Chambliss
had initially written the disputed compositions and that they formed the basis for the Album compositions;
3
Cham-bliss denied ever collaborating on any songs with Davis.
4
Chambliss and Miller also stated that they had orally agreed Chambliss would grant Miller certain rights in the compositions, although the existence and nature of the alleged oral agreement is in dispute.
5
See Davis,
B. Procedural History
Davis’s complaint alleges that defendants infringed her copyright to the disputed compositiоns by (1) recording and registering copyrights on “LOVE” and “Keep It Moving,” which were substantially similar to her compositions, and (2) falsely attributing authorship to (a) Blige, Miller, Holland, and Lawrence on “LOVE” and (b) Blige, Miller, and Stinson on “Keep It Moving.” Davis also alleges that defendants falsely designated the origin of their goods in violation of the Lanham Act § 43(a), 15 U.S.C. § 1125(a); 7 engaged in unfair competition; and were unjustly enriched. Finally, she claims that defendants’ acts were intentionally designed to mislead the public in violation of N.Y. Gen. Bus. Law §§ 349 and 350. 8
Following the completion of discovery, defendants moved for summary judgment on the ground that Chambliss had transferred his rights in the disputed compositions to Miller through an oral agreement before the compositions were used by Miller, or, alternatively, on the ground that the written transfer agreements conveyed the copyrights retroactively.
See Davis,
The District Court agreed. In a memorandum and order filed November 22, 2005, it declined to determine whether the written ratification of a prior oral transfer could satisfy the Copyright Act’s requirement that transfers of copyright ownership be in writing, 17 U.S.C. § 204(a), or whether the transfer agreements indeed ratified a prior oral agreement between Chambliss and Miller. Instead, it held that Chambliss could “cure past infringement” through the grant of a retroactive assignment of the copyright.
Davis,
DISCUSSION
In reviewing a grant of summary judgment, we draw all factual inferences in favor of the nonmoving party and review the matter
de novo. See, e.g., Miller v. Wolpoff & Abramson, L.L.P.,
The question of whether one joint owner of a copyright can retroactively transfer his ownership by a written instrument, and thereby cut off the accrued rights of the other owner to sue for infringement, is an issue of first impression in the courts of appeals. Although the Copyright Act itself is silent on the issue of retroactive transfer or license, we conclude that such retroactive transfers vio *98 late basic principles of tort and contract law, and undermine the policies embodied by the Copyright Act.
A. General Principles of Copyright Law
We revisit some general principles of copyright law in order to place the instant case in its legal context.
Copyright, of course, is a federal grant of a property interest in the production, replication, publication, and distribution of certаin classes of “original works of authorship fixed in any tangible medium of expression,” 17 U.S.C. § 102(a), including musical compositions,
Id.
§ 102(a)(2).
9
“Copyright in a work protected under [the Copyright Act] thus initially vests in the author or authors of the work.” 17 U.S.C. § 201(a). “The authors of a joint work are co[-]owners of copyright in the work,”
id.,
and, as described in the House Report accompanying passage of the Copyright Act, are to “be treated generally as tenants in common, with each co[-]owner having an independent right to use or license the use of a work, subject to a duty of accounting to the other co[-]owners for any profits.” H.R.Rep. No. 94-1476, at 121 (1976);
see Thomson v. Larson,
[t]he rights of property which the [co-owner] had were transferable by sale and delivery, and there is no distinction, indеpendent of statute, between [copyrighted property] and property of any other description. The right to sell and transfer personal property is an inseparable incident of the property. An author or proprietor of a literary work or manuscript [or other work protected by the Copyright Act] possesses such a right of sale as fully and to the same extent as does the owner of any other piece of personal property. It is an incident of ownership.
Maurel v. Smith,
Like other forms of property ownership, copyright ownership is a “bundle of discrete rights” regarding the owner’s ability to use his property.
See Faulkner v. Nat’l Geographic Enters., Inc.,
The right to prosecute an accrued cause of action for infringement is also an incident of copyright ownership.
ABKCO Music, Inc. v. Harrisongs Music, Ltd.,
Early in the twentieth century, we stated in the copyright context the venerable principle of the law of property that, while an owner may convey any of his rights to others permanently or temporarily, he may not convey more than he owns.
Maurel,
An owner may not, however, convey the interests of his fellow co-owners without their express written consent, even if the transferee has no notice of the non-consenting owners’ interest.
See Crosney v. Edward Small Productions,
A co-owner may grant a
nonexclusive
license to use the work unilaterally, because his co-owners may also use the work or grant similar licenses to other users and because the non-exclusive license presumptively does not diminish the value of the copyright to the co-owners.
See Meredith v. Smith,
B. Retroactive Licenses and Transfers Are Invalid
In this case, we deal with the question of whether a copyright co-owner — who, according to the legislative history of the Copyright Act, we are to treat as a tenant in common,
see ante
page 98 —can convey his copyright interest to a third party retroactively, thereby defeating a claim of infringement asserted against that third party by another co-owner. In
Eden Toys,
we held that a later writing could memorialize or confirm an earlier oral agreement.
Eden Toys,
We conclude that the district court decisions relied upon by the District Court are distinguishable from the instant case insofar as they involved retroactive licenses granted pursuant to negotiated settlements of accrued infringement claims.
See, e.g., Country Road Music,
We believe that reliance on cases involving settlements is misplaced. Licenses and assignments function differently from settlements and releases, and the use of the term “retroactive license” for “settlement” or “release” by the parties causes unnecessary confusion and potentially creates legal mischief. Settlements are generally retrospective and exclusively between the parties to the settlement — the unauthorized user and the owner; and, absent clear language to the contrary, they are not licenses for future use. The Seventh Circuit has aptly observed that “[a] settlement agreement [is] nothing more than a promise by [one party] to pay liquidated damages for past infringements in return for a dismissal of the infringement suit. [The party] erroneously equates a settlement for past infringement with a license for prospective use.... ”
Ransburg Electro-Coating Corp. v. Spiller & Spiller, Inc.,
A settlement agreement can only waive or extinguish claims held by a settling owner; it can have no effect on co-owners who are not parties to the settlement agreement. It is a venerable principle of New York co-tenancy law, for example, that “[o]ne tenant in common can settle for or release his interest in ... personal property, but he cannot settle for or release the interest of his co-tenants. If one tenant in common should settle for his portion of the damages before action, the other may sue without joining him.”
Jackson v. Moore,
Licenses and assignments, however, are prospective; they permit use by a non-owner who would not otherwise have a right to use the property. “In its simplest form, a license means only leave to do a thing which the licensor would otherwise have a right to prevent.”
Western Elec. Co. v. Pacent Reproducer Corp.,
The co-owner’s right that would be extinguished by a rule permitting retroactive licenses or assignments' — the right to sue for infringement — is a valuable one; indeed, it is one of the most valuable “sticks” of the “bundle of rights” of copyright.
See Silvers v. Sony Pictures Entm’t, Inc.,
As we have observed, “[u]nder general principles of [tort] law, a cause of action accrues when conduct that invades the rights of another has caused injury. When the injury occurs, the injured party has the right to bring suit for all of the damages, past, present and future, caused by the defendant’s acts.”
Leonhard v. United States,
A retroactive license or assignment that purports to eliminate the accrued causes of action for infringement held by a co-owner who is not party to the license or agreement also violates the fundamental principle of contract law prohibiting the parties to a contract from binding nonparties.
See, e.g., EEOC v. Waffle House, Inc.,
None of what we say above should be read as preventing an owner and an infringer from settling infringement claims among themselves.
See ABKCO Music, Inc. v. Harrisongs Music, Ltd.,
We find support for this holding in the law of patents. Although patent and copyright law function somewhat differently, courts considering one have historically looked to the other for guidance where precedent is lacking.
See Sony Corp. of Am. v. Universal City Studios, Inc.,
There is little from a policy perspective to recommend a rule that allows retroactive licenses or assignments, and there are
*105
two strong reasons disfavoring them — (1) the need for predictability and certainty and (2) discouragement of infringement. A rule permitting retroactive assignments and transfers would inject uncertainty and unpredictability into copyright ownership, contrary to the intent of Congress in enacting the Copyright Act of 1976.
See, e.g., Cmty. for Creative Non-Violence v. Reid,
This case demonstrates why permitting such an indeterminate legal regime could create substantial mischief. Construing the facts in a light most favorable to Davis, as we are required to do in the case of a summary judgment, Miller had no right to use or license the disputed compositions at the time they were used on the Album or at the time he licensed them to the third-party defendants. The third-party defendants are, in turn, potentially liable for infringement to Davis because they never obtained a legitimate right to use the disputed compositions. 13 If Chambliss were *106 permitted to assign his interest in the disputed compositions retroactively, Davis’s infringement claims would fail not only against Miller (because Miller would be “retroactively authorized” to use the compositions as a co-owner), but also against the third-party defendants, whose illegitimate licenses would retroactively become legitimate because Miller (by operation of the legal fiction of retroactivity) would now have been authorized as a co-owner to grant third parties the right to use the disputed compositions. Thus, Chambliss’s alleged retroactive assignment to Miller of the disputed compositions, for consideration of one dollar each, would have the effect of unraveling valuable accrued infringement claims against not only the retroactive assignee (Miller) but also his licensees. 14
The second policy reason disfavoring retroactive copyright transfers and licenses that extinguish the right of other co-owners is that such retroactive activity lowers the cost of infringement to infring-ers, thus making infringement more attractive. An infringer could “buy” his way out of an infringement suit, in which an injured owner may seek enhanced statutory damages and costs,
see
17 U.S.C. § 504, by paying a single co-owner for a license or assigned copyright interest. A retroactive license or assignment that can be obtained from a co-owner not bringing suit, or one willing to settle for a lower price than the co-owner bringing the action, is likely to cost much less than the value of the copyright interest including the cost of litigation. The result is that infringement is encouraged and rewаrded. This economic incentive to infringe runs directly counter to the intent of Congress in passing 17 U.S.C. § 504 — namely to “compensate the copyright owner for losses from the infringement, and ... to prevent the infringer from unfairly benefitting from a wrongful act.”
Abeshouse v. Ultragraphics, Inc.,
*107 For the reasons stated above, we conclude that the written transfer agreements, through which Chambliss allegedly transferred his interests in the disputed compositions to Miller, cannot extinguish Davis’s accrued infringement claims against any of the defendants. On remand, the District Court shall adjudicate Davis’s infringement claims without giving effect to the purported retroactive assignment of Chambliss’s interest in the disputed compositions. 16
We now turn to address defendants’ alternative argument regarding ratification. Miller argued before the District Court that Chambliss transferred his interests in the disputed compositions (and potentially other compositions) to Miller in 1998 or early 1999, in an alleged oral agreement, before the alleged infringement occurred. Miller and his co-defendants acknowledged that the Copyright Act requires all transfer agrеements — including assignments— to be in writing,
see
17 U.S.C. § 204(a), but argued that the transfer agreements ratified the earlier oral agreement.
See Davis,
We conclude that, even if an oral agreement assigning Chambliss’s copyright in the disputed compositions to Miller was reached in 1998 or 1999, the oral agreement cannot be “ratified” retroactively by the 2004 transfer agreements to defeat Davis’s accrued infringement claims. This is so for the same reasons we cannot give the transfer agreements themselves retroactive effect. If there was no written agreement between Miller and Chambliss documenting the alleged assignment at the time the disputed compositions were used by defendants, defendants had no legal right to use the disputed compositions, 17 and Davis’s right to sue fоr infringement accrued. Chambliss and Miller could not extinguish Davis’s accrued infringement *108 claims by “ratifying” an earlier oral agreement that had no legal effect at the time it was made, because doing so would require us to employ a legal fiction- — treating the transfer agreements as if they were written in 1998 or 1999, rather than 2004 — to obtain a counterintuitive and inequitable result.
Our opinion in
Eden Toys
is readily distinguishable from the facts of the instant case. In
Eden Toys,
we held that a third-party infringer could not assert the invalidity of an alleged 1975 oral agreement for an exclusive license, which was allegedly memorialized in a 1980 writing, to defeat an infringement claim brought by the exclusive licensee.
See Eden Toys,
In this case, however, the “third party” is a copyright holder who
does
have a dispute with the alleged licensee or transferee and who would stand to lose her accrued rights to sue for infringement if an allegedly fraudulent oral agreement were given legal effect. Thus it would be anomalous
not
to let Davis invoke § 204(a) in support of her infringement claims. Even if a third-party infringer cannot, under
Eden Toys,
contest the validity of an oral transfer agreement under pre-1978 copyright law that is later confirmed in writing,
see Magnuson v. Video Yesteryear,
*109 CONCLUSION
Inasmuch as the alleged retroactive written agreements purporting to transfer Chambliss’s copyright interests to Miller could not also transfer Davis’s copyright interests, Davis’s accrued causes of action for infringement were not affected by the agreement between Chambliss and Miller. Accordingly, the District Court erred in granting summary judgment to defendants. The District Court’s order of November 22, 2005 is hereby vacated and the cause is remanded for proceedings consistent with this opinion.
Notes
. "Platinum” status, a term of art of musical-recording sales certification created by the Recording Industry Association of America, refers to the sale of over one million copies of a musical recording. Thus, "triple platinum” status means over 3 million copies of the Album were sold. See Recording Industry Association of America, Gold and Platinum, http://www.riaa.com/goldandplatinum.php (last visited Aug. 8, 2007).
. Miller testified that he and Blige contributed to the "revised” version of "LOVE.”
. Chambliss’s deposition testimony is somewhat confused on this point. Although during his deposition he categorically denied ever having written songs with Davis, Chambliss identified several instances in which Davis’s handwriting or name appeared in his papers documenting several songs. Chambliss explained this documentation as either identifying songs meant for her as a performer, or areas where she added unauthorized verses.
. Miller’s and Chambliss’s deposition testimony contain inconsistent descriptions of the nature and timing of the alleged oral agreement. Miller stated during his deposition that he and Chambliss had a conversation "[plrobably like the end of '98, '99 ... somewhere in there,” during which Chambliss told him, "basically, 'Any song that I have written, if it needs to be used at any point in time, use it. It is yours.’ ” Miller said that this agreement was never written down, and that he never compensated Chambliss for any songs that Chambliss had given to him.
According to Chambliss, he "sign[ed] all of [his] songs over to [Miller]” because he "knew [Chambliss] was going to be in prison, and [he] knew [Miller] could handle everything.” Chambliss also described the alleged oral agreement alternatively as an agreement that “[Miller] can
use
all of [the songs].” As the District Court noted, however, Chambliss was inсarcerated sometime in 1997, and again from 2001 to 2003; thus, it appears that Chambliss could not have known "he was going to be in prison” during late 1998 or early 1999, when Miller says that the oral agreement was reached.
See Davis,
.When asked during his first deposition on June 24, 2004, if there was any written agreement memorializing the transfer of his interest to Miller, Chambliss first said “No, he's my son, I don’t need a written agreement.” But when questioned further, he changed his answer and stated, “Yeah, there is a signed document.” When asked about the details of that signed document, Chambliss responded:
Q.... Do you recall what songs were listed on that document?
A. L-O-V — I'm not sure.
Q. Do you remember if there any other songs besides L-O-V-E that were listed?
A. I'm not positive.
Q. Do you know if there were more than five songs listed?
A. I’m not positive.
Q. Do you know why [Miller] was asking you to sign that document?
A. Yes.
Q. Why?
*96 A. Because he was trying to sell them [the songs].
Q. Do you know who he was going to try to sell them to?
A. Not right offhand. There was a lot of songs.
The alleged agreement was not made available to Davis, however, until August 8, 2004— the day before Chambliss’s
second
deposition — when
two
written agreements transferring Chambliss's rights in the disputed compositions (but no others) to Miller were shown to Davis. The District Court took note that Chambliss’s vague testimony during his June 24, 2004 deposition appeared to be inconsistent with the written agreements that he allegedly signed the day before,
see Davis,
. Davis did not respond to defendants’ motion for summary judgment on this claim, and does not appeal the resulting dismissal of her Lanham Act § 43(a) claim.
. N.Y. Gen. Bus. Law § 349 reads in relevant part as follows: "(a) Deceptive acts or practices in the conduct of any business, trade or commerce or in the furnishing of any service in this state are herеby declared unlawful.”
N.Y. Gen. Bus. Law § 350 reads in relevant part as follows: "False advertising in the conduct of any business, trade or commerce or in the furnishing of any service in this state is hereby declared unlawful.”
. The United States Constitution confers on Congress the power "[t]o promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries.” U.S. Const, art 1, § 8, cl. 8. In the exercise of that power, Congress regulates copyright of creative works through the Copyright Act.
. Under current copyright law, exclusive licenses are recognized as a type of an ownership interest, conveying a particular exclusive right of copyright.
See
17 U.S.C. § 101 (" 'Copyright owner', with respect to any one of the exclusive rights comprised in a copyright, refers to the owner of that particular right.”). Exclusive licensees may sue without joining the copyright owners, 17 U.S.C. § 501, and exclusive license agreements must be in writing, 17 U.S.C. § 204(a);
see also Eden Toys, Inc. v. Floretee Undergarment Co.,
Under the earlier version of the copyright statute, the Copyright Act of 1909, copyright ownership was generally considered indivisible; thus, the individual rights comprising the bundle of copyright property rights could not be separately assigned, and exclusive licenses granted more limited rights — for example, exclusive licensees had to join copyright owners in suits for infringement. Apparently, because exclusive licenses were not transfers of ownership, oral agreements granting exclusive licenses were permissible. See 3 Nimmer § 10.01[C].
. Infringement has long been recognized as a tort.
See Ted Browne Music Co. v. Fowler,
. Venegas-Hemandez had no occasion to address the retroactivity issue — what it described as a "recherché area of copyright law,” id. — because the party seeking to benefit from a retroactive license in that case did not adequately pursue it.
. Miller could be exposed to liability under a theory of contributory infringement or for unauthorized licensing of the disputed compositions even if he himself had not used the disputed compositions without authorization. While an owner of a copyright may assign an expectancy of a renewal interest in that copyright validly,
see Fred Fisher Music Co. v. M. Witmark & Sons,
In any event, Miller would have exceeded his authority as a co-owner to the extent he granted a third-party an exclusive license to the disputed compositions, because he did not join Davis to the licensing agreement. See 17 U.S.C. § 201(d)(2); 1 Nimmer § 6.11 (noting prohibition on one co-owner granting an exclusive license without consent of co-owners).
. We note that were we to permit retroactive transfers of copyright interests in these circumstances, infringers who obtained a retroactive transfer of a copyright interest could not only grant retroactive licenses but also sue other past infringers of the copyright. These retroactive co-owners could then issue retroactive licenses to these other past in-fringers, thwarting yet other potential infringement suits by a non-licensing co-owner.
. If the retroactive agreement were given effect, the possibility that Davis could seek an accounting from Miller,
see Shapiro, Bernstein & Co. v. Jerry Vogel Music Co.,
. We express no opinion on whether the transfer agreements should be given prospective effect, or — if they are given prospective effect — whether the transfer agreements would limit Davis's remedies against the third-party defendants.
. The following discussion assumes that Davis proves at trial that she holds copyright in the disputed compositions, and that the Album compositions infringed her copyright in the disputed compositions.
. Because we hold that a written confirmation of an earlier oral transfer agreement cannot extinguish a copyright owner's accrued infringement claims, we need not decide whether there ought to be, as a general rule, any other limitations on permitting oral transfer agreements to be validated at a later date by a writing that complies with the requirements of § 204(a).
Cf. Konigsberg Int'l Inc. v. Rice,
We also need not decide whether Cham-bliss's alleged oral agreement with Miller might be interpreted to have granted Miller a valid nonexclusive license to use the disputed compositions.
