Severity moderate: test met: data of others (authors' works) touched with a bounded scope stated, over 480,000 works included in the settlement.

Anthropic's Claude chatbot was trained on books, and the authors who sued said the company used pirated copies without permission. A federal judge in San Francisco granted final approval of a $1.5 billion class settlement, rejecting objections that it was too small. An earlier ruling had found that training on books was fair use, but that keeping pirated books in a central library infringed copyright. Authors and copyright holders filed claims covering over 92% of the more than 480,000 works in the settlement. Some authors and publishers opted out and have ongoing lawsuits. The company is now required to destroy the pirated material.
