Music publishers accuse Anthropic and co-founders Dario Amodei and Benjamin Mann of illegal piracy.

Why It Matters

The case follows earlier litigation, such as Bartz v. Anthropic, where a court ruled that using copyrighted data for AI training was legal, but acquiring files through piracy was illegal, leading to a $1.5 billion payout order. This new suit broadens those accusations, establishing critical precedents regarding how AI labs acquire training datasets from commercial content creators.

Industry Reaction

An Anthropic spokesperson stated to TechCrunch that the company disagrees with the publishers' claims and intends to defend itself robustly in court.
