币界网报道：Anthropic secured a partial victory in a copyright lawsuit regarding its AI training data after a California federal judge dismissed several claims from music publishers. The publishers, including Concord Music Group and Universal Music, alleged that Anthropic's AI models reproduced copyrighted song lyrics without permission. While Judge Araceli Martínez-Olguín dismissed claims of direct and vicarious copyright infringement, she allowed the plaintiffs to amend their complaint regarding contributory infringement. The case highlights ongoing legal debates over whether AI companies must license copyrighted material used to train their models. Anthropic argued its use of lyrics falls under fair use, while publishers contend it harms songwriters. The ruling follows similar lawsuits against OpenAI and Microsoft over AI-generated content.
