Major music publishers including Sony Music Publishing and Warner Chappell have filed a lawsuit against AI lab Anthropic and co-founders Dario Amodei and Benjamin Mann, accusing the company of conducting a blatant campaign of illegally torrenting, scraping, and downloading copyrighted works.

The lawsuit was filed in the U.S. District Court for the Northern District of California, with publishers accusing Anthropic of using thousands of copyrighted works to train its Claude AI model without permission.

An Anthropic spokesperson responded via an emailed statement to TechCrunch, stating that the company disagrees with the publishers' claims and intends to defend itself robustly in court.

This legal action highlights the intensifying clash between creative industries and artificial intelligence developers over training data acquisition methods. As copyright holders push back aggressively against unauthorized scraping and piracy, the outcomes of these high-stakes lawsuits could fundamentally reshape how AI companies source and license copyrighted content for future models.

This is not the first intellectual property lawsuit faced by Anthropic. Previously, the landmark Bartz v. Anthropic case resulted in a $1.5 billion judgment after a judge ruled that while training AI models on copyrighted works might be disputed, acquiring that content through piracy is strictly illegal.
