Music publishers sued Anthropic on 10/18/2023, alleging it copied copyrighted song lyrics without permission to train Claude and that Claude reproduced them in outputs. Anthropic denies infringement and argues its training use is fair use. In 2025 a federal judge denied the publishers' preliminary-injunction request.

What this means for youCourts are still deciding whether AI companies may train on copyrighted work without permission. The outcome affects songwriters, publishers, and anyone whose writing or music might be used to build AI tools.
