Sony Music Publishing, Warner Chappell and several other music publishers have filed a lawsuit against Anthropic and its co-founders, Dario Amodei and Benjamin Mann, alleging that the company used copyrighted music and related materials without permission to train its AI system, Claude.
The complaint was submitted to the U.S. District Court for the Northern District of California and argues that Anthropic relied on thousands of protected works gathered through torrenting, scraping and downloading. The publishers say the practice amounted to large-scale misuse of intellectual property.
This is not the first legal challenge Anthropic has faced over AI training data. Earlier cases involving authors and music-rights holders have already pushed the company into major copyright disputes, including a landmark settlement tied to the use of protected books. The new filing broadens that debate by focusing on lyrics, sheet music and other music-related content.
As AI models become more capable, the question of how creative works are sourced is moving to the center of the industry. The outcome of cases like this may help define clearer standards for responsible AI development in the years ahead.
