Anthropic, music publishers square off on ‘fair use’ defence in AI copyright case

In brief

On Oct 21, 2026, Anthropic asked a judge in California to find that its use of millions of song lyrics to train the Claude chatbot is covered by fair use under US copyright law. The company is trying to end a lawsuit against it.

The dispute matters because it tests whether training AI systems on copyrighted creative works can be defended as fair use. The supplied text is cut off, so it does not say how the judge ruled, what the publishers argued, or what remedies are sought.

Main points

  1. Anthropic made its request to a judge in California on Oct 21.
  2. The training material at issue is described as millions of song lyrics.
  3. The chatbot named in the case is Claude.
  4. Anthropic wants the lawsuit scuttled by a ruling that its use is fair use under US copyright law.

The problem

Anthropic's use of millions of song lyrics to train Claude is being challenged in a copyright lawsuit, and the company is asking a judge to rule that the use is protected as fair use.

The rundown

The article is datelined San Jose, California, and says Anthropic urged a judge to rule in its favour on Oct 21. The request is framed as an attempt to scuttle a lawsuit, so it is a legal argument rather than a decided outcome.

The opening line states that Anthropic used millions of song lyrics to train Claude. The text then describes the company's position that this use falls under the fair use doctrine of US copyright law. The headline indicates music publishers are on the other side, but the supplied body does not set out their arguments.
