Anthropic urged a judge in California on Wednesday to rule that the AI company's use of millions of song lyrics to train its chatbot Claude is protected as "fair use" under US copyright law, as it seeks to scuttle a lawsuit brought by Universal Music Group and other music publishers.
US District Judge Eumi Lee did not rule at a hearing in San Jose but pressed both sides on the fair use question, which could be key to dozens of other high-stakes copyright infringement cases in the AI era.
