Anthropic sued by music publishers over alleged use of tens of thousands of songs

A lawsuit alleging the misuse of copyrighted music to train artificial‑intelligence models has been filed against Anthropic, the startup behind the Claude chatbot. Sony Music Publishing and Warner Chappell, two major music publishers representing songwriters and composers, claim that Anthropic used “tens of thousands” of copyrighted works without permission in the development of its language‑model technology. The plaintiffs are seeking multibillion‑dollar damages for the alleged infringement and for the unauthorized use of their catalogues.

The suit argues that the AI training process incorporated large amounts of copyrighted audio and lyrics, providing the models with proprietary content that was never licensed. Anthropic maintains that it complied with applicable copyright laws and that the data used were either public domain or properly licensed. The case highlights the growing legal scrutiny of how AI companies source and use copyrighted material during model training, raising questions about the balance between technological innovation and intellectual‑property rights.

If the court sides with Sony and Warner Chappell, the decision could set a precedent for how AI firms obtain and use copyrighted works, potentially reshaping licensing practices in the industry. The lawsuit remains pending, with both parties preparing for a protracted legal battle that could influence future AI‑training protocols.
