The story
Units of Sony Music and Warner Music filed a federal lawsuit in Northern California on Friday accusing Anthropic, CEO Dario Amodei, and co-founder Benjamin Mann of mass copyright infringement. The 48-page complaint alleges the defendants illegally torrented and scraped copyrighted musical works to train and operate the Claude AI model series. Plaintiffs characterize the alleged conduct as one of the largest intellectual property thefts in history and seek statutory damages reaching hundreds of thousands of dollars per work. This legal action follows Anthropic’s record $1.5 billion copyright settlement with authors in September 2025. The new suit suggests that previous agreements regarding text data do not immunize AI developers against claims involving distinct creative mediums. Industry observers view this filing as the beginning of protracted litigation defining intellectual property rights for generative AI training on audio content.
