Sony Music Publishing, Warner Chappell, and several other music publishers have filed a lawsuit against AI company Anthropic and its co-founders, Dario Amodei and Benjamin Mann. The complaint, filed in the U.S. District Court for the Northern District of California, alleges that Anthropic engaged in a campaign of illegal scraping and downloading of copyrighted works to train its Claude AI model.
Allegations of Copyright Infringement

Anthropic case involving a group of authors.
