Sony Music and Warner Chappell Sue Anthropic Over Copyright Infringement

ai-technology · 2026-08-29

Sony Music Publishing and Warner Chappell, along with other music rights holders, have initiated a lawsuit against AI firm Anthropic and its founders, Dario Amodei and Benjamin Mann, in the Northern District of California. Filed on Friday, the suit accuses Anthropic of unlawfully seizing copyrighted material to develop its AI model, Claude, which reportedly incorporates a vast array of protected content, including lyrics and sheet music. This legal challenge follows a previous infringement case involving Concord Music Group and Universal Music Group, which led to a substantial $1.5 billion ruling against Anthropic. The company has yet to address the new allegations.
