The judge on Tuesday rejected opt-out requests from several others who made the request too late.But she allowed two other plaintiffs to exit the settlement due to extenuating circumstances.In one case, an author was not notified of the settlement in time, and in another the plaintiff was recovering from a stroke.Anthropic “intentionally downloaded known pirated copies of books from the internet, made unlicensed copies of them, and then used those unlicensed copies to digest and analyze the copyrighted expression—all for its own commercial gain,” the authors’ 2024 complaint said.Last June, U.S. District Judge William Alsup ruled that Anthropic could utilize purchased copyrighted books to train its AI models under so-called “fair use.”That’s a legal doctrine that allows the use of copyrighted material without getting permission from the copyright owner.But since Anthropic had also initially used some pirated copies, that was not fair use, and he ordered the case to go to trial in December.“That Anthropic later bought a copy of a book it earlier stole off the internet will not absolve it of liability for the theft, but it may affect the extent of statutory damages,” Alsup said in his ruling.Reuters contributed to this report.
