A federal judge sides with Anthropic in lawsuit over training AI on books without authors’ permission

In a landmark ruling, Federal Judge William Alsup has determined that Anthropic, an artificial intelligence company, is permitted to train its AI models on published books without needing permission from the authors. This decision represents a significant moment in the ongoing debate over the intersection of AI development and copyright law, affirming the stance that the fair use doctrine can protect AI firms when utilizing copyrighted materials. The implications of this ruling are profound, especially for authors, artists, and publishers who have initiated numerous lawsuits against major tech entities, including OpenAI, Meta, and Google. While this verdict does not guarantee that other judges will echo Judge Alsup’s interpretation, it establishes a potential precedent that favors technology companies at the expense of creative rights. The legal disputes surrounding fair use are complex, often hinging on the specific circumstances of each case. Fair use considerations include the purpose of the use, whether it is for commercial gain, and the transformative nature of the resulting work. Prior to this ruling, the outcome of similar cases remained uncertain, with companies like Meta also advocating for fair use in their defense. In the particular case of Bartz v. Anthropic, the plaintiff authors raised concerns about how Anthropic obtained and stored their works. They claimed that the company aimed to build a comprehensive "central library" of all published texts, with allegations that many of these books were illegally downloaded from piracy websites. Although the judge ruled in favor of Anthropic's training practices under fair use, the court has ordered a trial to further examine the implications of the alleged piracy related to the central library. Judge Alsup stated, "We will have a trial on the pirated copies used to create Anthropic’s central library and the resulting damages." He emphasized that while Anthropic's later acquisition of a legitimate copy of a book does not erase the liability for prior theft, it could influence the calculation of statutory damages in the case.
