Meta Wins Copyright Lawsuit Over AI Book Training, But Fair Use Debate Continues

A U.S. federal judge ruled in favor of Meta Platforms (NASDAQ:META) on Wednesday, dismissing a copyright lawsuit brought by a group of authors. The authors claimed Meta unlawfully used pirated versions of their books to train its artificial intelligence model, Llama, without permission or compensation.

U.S. District Judge Vince Chhabria in San Francisco concluded that the authors failed to provide sufficient evidence that Meta's AI training practices caused market harm to their works. However, he emphasized that his ruling does not mean Meta’s actions were necessarily lawful under copyright law. Instead, he stated that the plaintiffs did not present the right legal arguments or build a strong evidentiary record.

Chhabria’s ruling contrasts with a separate decision earlier in the week by another judge in San Francisco, who found that Anthropic's use of copyrighted material to train its AI constituted fair use.

While Meta welcomed the decision and defended the use of copyrighted works under the fair use doctrine as essential for developing transformative AI technology, the authors' legal team at Boies Schiller Flexner criticized the ruling, calling Meta’s actions “unprecedented pirating.”

The case is part of a broader legal battle involving AI developers like OpenAI, Microsoft (NASDAQ:MSFT), and Anthropic, all of whom face lawsuits from copyright owners including writers and news publishers. These cases center on whether AI training on copyrighted data without consent qualifies as fair use.

Chhabria acknowledged the concern that generative AI could harm creative industries by producing content rapidly and cheaply, undermining incentives for human creators. He noted that while current legal standards allowed Meta to prevail in this instance, the broader issue of fair use in AI remains unresolved.
