Sony Music Publishing and Warner Chappell Music filed a massive copyright infringement lawsuit against artificial intelligence startup Anthropic in a federal court in the Northern District of California, according to court documents cited by Music Business Worldwide and reported by Terra and AI Art. The lawsuit alleges that the company systematically downloaded, extracted, and used tens of thousands of copyrighted musical compositions and pirate books via BitTorrent to train its Claude AI models without permission or licensing fees.
Massive Copyright Infringement Claims Against Anthropic and Founders
The 48-page complaint targets not just the startup, but also Dario Amodei and co-founder Benjamin Mann as individual defendants. According to the reporting by Terra, the legal action details how company employees allegedly downloaded millions of pirated books and vast acervos of musical compositions. The lawsuit points to specific tracks utilized by the AI models, including popular songs like “Ain’t No Mountain High Enough,” “All I Want for Christmas is You,” “Eye of the Tiger,” “Here Comes Santa Claus,” and “Paper Rings.”
Financial Stakes and Statutory Damages
The music publishers are seeking substantial financial penalties that could reach billions of dollars, according to AI Art. Under the filed claims, the publishers are asking for statutory damages of up to US$ 150 mil for each intentionally infringed work. Furthermore, the suit requests up to R$ 25 mil per violation for the alleged removal of copyright management information. While the exact total of violated works is still being quantified, the filing notes that “thousands and thousands of copyrighted musical compositions” were improperly acquired and copied.
Broader Legal Battleground for Generative AI
This California action represents a significant escalation in the ongoing legal confrontations between the music industry and AI developers. Terra notes that other major entities—such as Universal Music Publishing Group, Concord Music Group, and ABKCO—previously initiated a separate lawsuit in Nashville in October 2023 involving roughly 500 songs, a case that later migrated to California. Additional legal challenges from BMG and Round Hill Music further solidify a unified front among music publishers against unauthorized data harvesting.
