Last year, the United States Supreme Court held that as long as a claim is timely filed, damages may be recovered for any loss or injury, including losses incurred more than three years before the claim is filed (Warner Chappell Music. v. Nealy). The Court expressed no opinion about whether the Copyright Act’s three-year limitation period begins to run when the infringing act occurs or when the victim discovers it, leaving that question for another day. “Another day” arrived, but the Court still declined to address it. What, if anything, can be made of that?
Statute of Limitations for Copyright Infringement
The Copyright Act imposes a 3-year limitations period for copyright infringement claims. Specifically:
No civil action shall be maintained under the provisions of this title unless it is commenced within three years after the claim accrued.
But when does a claim accrue? That is the (potentially) million-dollar question.
According to the “incident of injury” rule, an infringement claim accrues when an infringing act occurs. Petrella v. Metro-Goldwyn-Mayer, Inc., 572 U. S. 663, 670 (2014). Under this rule, an infringement victim who did not learn about an infringing act until three years after it occurred would be out luck.
Courts in many circuits, however, apply an alternative rule. Known as the “discovery rule,” it holds that a copyright infringement claim accrues when “the plaintiff discovers, or with due diligence should have discovered, the injury that forms the basis for the claim.” William A. Graham Co. v. Haughey, 568 F. 3d 425, 433 (CA3 2009) (internal quotation marks omitted). According to Patry on Copyright, this is the majority rule.
If a court applies the discovery rule, then the infringement complaint must be filed within three years after the victim learns or should reasonably have learned of the infringing act, even if that act occurred more than three years earlier.
The Look-Back Period for Damages
As I explained in a previous blog post, the United States Supreme Court did not have the question about the validity of either accrual theory before it in Warner Chappell Music. Accordingly, it did not address the issue. Instead, the Court limited itself to deciding only the specific question before it, namely, whether damages can be claimed for all injuries that occurred before the victim learned (or reasonably should have learned) of an infringing act. The Court held that they can be. And this is true even for losses occurring more than three years before the infringement was discovered. Statutes of limitations only determine when a claim may be filed; they do not limit the look-back period for recovering damages for injury. “The Copyright Act contains no separate time-based limit on monetary recovery.” Warner Chappell Music, supra.
It must be kept in mind that the discovery rule has an important proviso. The clock starts clicking on a claim from the first date a victim actually knew or should have known of an infringement. In many cases, it may become more difficult to convince a judge that the victim’s unawareness of the infringing act was reasonable if a lot of time has gone by since the infringement occurred. Reasonableness, however, depends on all the facts and circumstances, so it has to be decided on a case-by-case basis.
RADesign, Inc. v. Ruthie Davis et al.
Michael Grecco Productions, Inc. sued RADesign, Inc. and others for copyright infringement. The complaint alleged that the defendant’s infringing use of a copyright-protected photograph began on August 16, 2017, and that the plaintiff discovered it on February 8, 2021. The complaint was filed in October, 2021. As a result, the claim would be barred under the “incident of injury” rule because it was filed more than three years after the alleged infringement occurred. The complaint, however, was filed in the Second Circuit, a jurisdiction that recognizes the discovery rule. Therefore, the question became whether the failure to discover the infringement within three years was reasonable. The district court held that it was not. The court described the copyright owner in this case as “sophisticated” in detecting and litigating infringements and therefore not entitled to the benefit of the discovery rule.
The Second Circuit Court of Appeals reversed, declaring, “This ‘sophisticated plaintiff’ rationale has no mooring to our cases.”
The U.S. Supreme Court’s Denial of Certiorari
RADesign, Inc. filed a petition for certiorari to the United States Supreme Court. The sole question presented was “Whether a claim ‘accrue[s]’ under the Copyright Act’s statute of limitations for civil actions, 17 U.S.C. 507(b), when the infringement occurs (the ‘injury rule’) or when a plaintiff discovers or reasonably should have discovered the infringement (the ‘discovery rule’).” The petition argued that the Copyright Act does not explicitly provide for a discovery rule and asserted that the courts of appeal should not have adopted one.
Unlike in Warner Chappell Music, the Court now had the validity of the discovery rule in copyright infringement cases squarely before it. The Court, however, declined the invitation to review that question. On June 16, 2025, it denied certiorari.
What a Denial of Certiorari Means
Really, the only legal effect of a denial of certiorari is that the lower court’s decision stands. In this case, that would mean that the Second Circuit Court of Appeals’ decision remains in effect for that specific case. For the time being, anyway, attorneys can cite the reasoning and holding of the Second Circuit Court of Appeals decision as legal precedent in other cases.
What a Denial of Certiorari Does Not Mean
A denial of certiorari does not mean that the Supreme Court agreed with the Court of Appeals. The Court of Appeal’s decision sets a precedent in the Second Circuit, but the denial of certiorari does not have that effect. It simply means the Supreme Court has decided not to trouble itself with the question at this time.
Caveats
Copyright owners and practitioners should not read too much into this decision. Even if the discovery rule forecloses a finding of untimeliness on the face of a complaint, a defendant may still be able to assert untimeliness as an affirmative defense. Again, the reasonableness of delayed acquisition of knowledge of infringement must be decided on a case-by-case basis. Copyright owners and their attorneys should be vigilant in detecting infringement of protected works and diligent in timely filing claims.
