AI firm Anthropic is still facing copyright-infringement lawsuits from music publishers… and now the publishers are going in for what they hope will be the legal kill.

The publishers, who include various UMG subsidiaries as well as Concord Music Group and ABKCO Music, have filed for partial summary judgement against Anthropic in the case, which focuses on their allegations that the company’s Claude model was trained on their lyrics.

“Anthropic’s actions are quintessential infringement—not fair use,” claims the filing, which also reiterates the publishers’ claims that Claude’s outputs – its responses to users – are also clear copyright infringement.

“Anthropic trained Claude using Publishers’ lyrics precisely so the model could respond to queries for those lyrics, including by serving up unauthorized copies and derivatives of Publishers’ lyrics on demand, and Claude has repeatedly been put to that very use,” claims the filing.

“Training an AI tool to output copyrighted works on command is not transformative and plainly harms the market for the underlying works,” it adds.
