The lawsuit between Bartz and Anthropic: Exploring the Implications for Writers if Their Books Were Used in AI Training
In a groundbreaking development, a significant copyright infringement lawsuit has been filed against the AI company Anthropic. The case, which could reshape how AI companies handle copyrighted works, has been consolidated into one unified trial scheduled for December 1, 2025.
The lawsuit, originally filed by three authors in late 2023, alleges that Anthropic used their books, along with millions of others, to train its AI without permission. The authors affected by the case are Andrea Bartz, Charles Graeber, and Kirk Wallace Johnson, who claimed that Anthropic used their works without permission to train the AI assistant Claude.
The Authors Guild has launched a separate class action against Anthropic on behalf of authors whose works were allegedly downloaded from pirate libraries and used to train Claude. Thousands of authors could be represented under the Guild-backed action.
In June 20225, U.S. District Judge William Alsup issued a partial summary judgment, ruling that using pirated copies of books opens the door to significant liability. This ruling could potentially lead to billions in liability for Anthropic.
Anthropic has agreed to a "settlement in principle" regarding the Bartz v. Anthropic lawsuit. However, the details of the settlement are yet to be disclosed.
The court will release a comprehensive list of affected works, showing which books were used to train Anthropic's Claude AI models, on September 1, 2025. This list is expected to include works by authors from around the world, as some international authors may still be included if their books were scraped from pirate libraries.
The case against Anthropic is not the only one of its kind. Multiple suits have been filed against OpenAI over its use of copyrighted materials, though these cases are moving more slowly than Bartz.
If you've published a book, it's worth staying informed about the Bartz v. Anthropic case and the Authors Guild-backed class action. The outcome of these legal proceedings could have far-reaching implications for authors and the AI industry as a whole.
Richard Kadrey, one of the authors who have sued Meta over the use of their books to train its AI models, emphasized the importance of protecting authors' rights. "It's crucial that we stand up for our work and ensure that companies respect our intellectual property," he said.
The trial, scheduled to begin December 1, 2025, will focus on the use of pirated books and could lead to damages in the billions. The case could potentially set a precedent for how AI companies handle copyrighted works in the future, ensuring that authors are fairly compensated for the use of their work.
