On May 9, 2024, in Warner Chappell Music, Inc. v. Nealy, the U.S. Supreme Court ruled 6-3 that a copyright owner is entitled to monetary relief for timely infringement claims — i.e., claims brought within the Copyright Act’s statute of limitations — no matter when the infringement occurred. This could potentially allow some plaintiffs to claim damages stretching back many years into the past.

The majority “assum[ed] without deciding that a claim is timely under [Section 507(b)] if brought within three years of when the plaintiff discovered an infringement, no matter when the infringement happened.”
