Quick Summary

At a hearing on October 21 in San Jose, California, Anthropic defended its use of millions of song lyrics to train its chatbot Claude as protected under the "fair use" doctrine. The company faces a lawsuit from Universal Music Group and other publishers who claim that Claude’s ability to generate synthetic lyrics threatens their market. Judge Eumi Lee questioned both sides but did not rule on the case, which could set a precedent for dozens of similar AI copyright disputes. Anthropic argues that its AI training leads to transformative new content, while the publishers assert that it undermines human songwriters’ work and market.

Story summary

Anthropic, an AI company, faced off against Universal Music Group and other music publishers in a California court on October 21, 2026, arguing that its use of millions of song lyrics to train its chatbot Claude is protected under the "fair use" doctrine of US copyright law. During the hearing before US District Judge Eumi Lee in San Jose, Anthropic’s lawyer Sonal Mehta claimed that AI training results in transformative new content. In contrast, the publishers' attorney Matt Oppenheim argued that Anthropic's actions harm human songwriters by using lyrics to generate competing content. Claude reportedly received nearly 120,000 requests for "synthetic" lyrics over a six-month period, according to Oppenheim. The case could set a precedent for numerous other high-stakes copyright infringement cases involving AI technology.
