Blake Brittain , Reuters; US authors suing Anthropic can band together in copyright class action, judge rules

"A California federal judge ruled on Thursday that three authors suing artificial intelligence startup Anthropic for copyright infringement can represent writers nationwide whose books Anthropic allegedly pirated to train its AI system.

U.S. District Judge William Alsup said the authors can bring a class action on behalf of all U.S. writers whose works Anthropic allegedly downloaded from "pirate libraries" LibGen and PiLiMi to create a repository of millions of books in 2021 and 2022."
