Sony Music and Warner Chappell Sue Anthropic Over Alleged Copyright Infringement

Sony Music and Warner Chappell have filed a lawsuit against Anthropic in the US District Court for the Northern District of California, alleging widespread copyright infringement involving "tens of thousands" of copyrighted works.

The publishers are seeking up to $150,000 per infringed work, plus an additional $25,000 for each instance where identifiable copyright management information was stripped from the content. If the court awards the maximum damages, total potential liability could reach into the billions of dollars.

The lawsuit characterizes Anthropic's conduct as a "brazen campaign" of intellectual property theft and a "blatant violation" of copyright law. This legal action adds to Anthropic's mounting legal challenges in the copyright space—the company recently settled a separate suit brought by the publishing industry for $1.5 billion.

The case raises ongoing questions about how AI companies source training data for their models and the extent to which existing copyright law applies to machine learning practices.
