Sony Music, Warner sue Anthropic, alleging a "brazen campaign" of intellectual property theft

Sony Music Publishing, Warner Chappell, and other music publishers have sued Anthropic and co-founders Dario Amodei and Benjamin Mann, alleging illegal torrenting and downloading of copyrighted works to train Claude. Anthropic told TechCrunch it intends to defend itself robustly. The suit follows prior cases, including Bartz, where Anthropic was ordered to pay $1.5 billion after a judge ruled acquiring content through piracy was illegal.
