A U.S. federal judge dismissed a copyright lawsuit brought by thirteen authors against Meta Platforms, ruling that the authors "made the wrong arguments" in their complaint about Meta using their books to train AI systems. Judge Vince Chhabria's decision didn't address whether Meta's actions might violate copyright law under different legal theories, leaving room for future challenges. This case adds to growing legal precedents regarding AI training on copyrighted works, with courts increasingly considering the fair use doctrine as a potential defense for AI companies. While a victory for Meta, the dismissal doesn't resolve broader debates about copyright in AI, as similar lawsuits against OpenAI, Google, and Midjourney continue to work through the courts.
