Anthropic is facing a new **Anthropic copyright lawsuit** from Sony Music Publishing and Warner Chappell Music over the training data behind its Claude models. The publishers filed the complaint on August 28 in the US District Court for the Northern District of California, naming CEO Dario Amodei and co-founder Benjamin Mann as individual defendants.

The suit alleges that Anthropic copied tens of thousands of the publishers' musical compositions to train and operate Claude, drawing lyrics and sheet music from pirated collections including Library Genesis and the Pirate Library Mirror, from scans of physical books, and from licensed lyric services such as Musixmatch and LyricFind. The publishers call the alleged scheme among the largest and most blatant intellectual property thefts on record, and cite works tied to The Beatles, Taylor Swift and Michael Jackson, among them I Am the Walrus, Hallelujah, Eye of the Tiger, Ain't No Mountain High Enough and Paper Rings.

## What the Anthropic copyright lawsuit alleges

The 48-page complaint asserts that Claude reproduces copyrighted lyrics verbatim when prompted and that Anthropic's existing safeguards are easy to get around. The publishers are seeking statutory damages of up to $150,000 for each work willfully infringed and up to $25,000 for every removal of copyright management information. Applied across tens of thousands of works, the publishers frame the case as a multi-billion-dollar claim, and they are asking for a jury trial plus an order blocking Anthropic from using their catalog in AI training.

By naming Amodei and Mann alongside the company, the publishers put the individual decisions behind Claude's training data squarely before the court.

## Why this matters

For Claude users, the practical stakes are direct: a court order against Anthropic would mean the chatbot can no longer serve up protected lyrics, and output filtering could tighten across the board. For the wider AI industry, the Anthropic copyright lawsuit tests whether labs can keep building models on content scraped or torrented without licenses, and who pays when the provenance of training data is questioned. A ruling that holds either the company or its founders liable would raise the cost of that approach for every developer that follows.
