Sony Music Publishing sued Anthropic in the Northern District of California on August 28, alleging direct copyright infringement via torrenting, contributory infringement against Anthropic executives Dario Amodei and Benjamin Mann, and removal or alteration of copyright management information, per Chat GPT Is Eating the World. The suit closely mirrors Concord Music Group's second case against Anthropic, was filed by the same law firm, and is expected to land before Judge Eumi Lee, who already presides over both Concord suits and BMG v. Anthropic. It is the 13th copyright suit filed against Anthropic, per the outlet's litigation tracker.

Why it matters: Filed by the same firm behind Concord Music v. Anthropic II and expected before the same judge who already hears the Concord and BMG suits against Anthropic, the case adds a fourth music-publisher plaintiff to a cluster of litigation testing Anthropic's training practices on the same legal theories.
