Anthropic secures Fair Use Victory in AI Copyright Lawsuit
Updated June 24, 2025
Anthropic, an artificial intelligence company, has won a significant round in a copyright battle that could set a precedent for numerous other AI copyright lawsuits across the U.S. legal landscape.A court ruled that training its AI models on copyrighted material falls under the “fair use” doctrine, which permits unauthorized use of such material under specific conditions. This ruling addresses the complex intersection of artificial intelligence models, copyright law, and fair use.
Senior District Judge william Alsup issued a summary judgment order late Monday, stating, “The training use was a fair use.” Central to the ruling is the concept of “transformative” use, where the new work doesn’t simply substitute for the original but creates something new. Alsup added, “The technology at issue was among the most transformative many of us will see in our lifetimes.”
Chris Mammen, a managing partner at Womble Bond Dickinson specializing in intellectual property law, noted the significance of the decision. “This is the first major ruling in a generative AI copyright case to address fair use in detail,” Mammen said. “Judge Alsup found that training an LLM is transformative use-even when there is significant memorization.”
The lawsuit, Bartz v. Anthropic, a class action filed in U.S. District court for the Northern District of California by authors alleging copyright infringement, was initiated in August 2024. The plaintiffs claimed Anthropic used their works without permission.
While this represents a victory for Anthropic, its not without caveats. Alsup resolute that while the AI training itself constituted fair use, the authors can still proceed to trial regarding the company’s use of pirated copies of books.
The court order highlighted that Anthropic initially amassed a large library of pirated books, even after transitioning to training on legally purchased copies. “Anthropic downloaded over seven million pirated copies of books, paid nothing, and kept these pirated copies in its library even after deciding it would not use them to train its AI,” Alsup wrote. The court agreed with the authors’ argument that Anthropic should compensate them for these pirated copies.
The order concludes,”We will have a trial on the pirated copies used to create Anthropic’s central library and the resulting damages.” Neither Anthropic nor the plaintiffs’ lawyers offered immediate comments.
