A federal judge has given final approval to the $1.5 billion settlement between Anthropic, the company behind the Claude chatbot, and a group of authors who sued the company for unauthorized use of their works. The agreement, the largest ever in an AI copyright lawsuit, was approved by U.S. District Judge Araceli Martinez-Olguin of San Francisco, who took over the case after Judge William Alsup retired. The case raises critical questions about the boundaries between fair use and copyright infringement in the era of large language models.
The 2024 lawsuit and allegations of book piracy
In 2024, a group of authors filed a class-action lawsuit against Anthropic, claiming the company used pirated copies of their works to train the Claude model. According to the complaint, Anthropic allegedly collected more than 7 million copyrighted books illegally, storing them in a central repository for AI training. The issue quickly became a test case for data mining practices in artificial intelligence, drawing attention from scholars, lawyers, and industry activists.

Contrasting opinions from two judges on fair use
Judge Alsup, initially assigned to the case, ruled that using the works for training Claude constituted fair use but that storing pirated copies violated copyright. However, Alsup rejected the first version of the settlement in September 2025, calling it “incomplete and imposed on authors.” The revised version, approved by Judge Martinez-Olguin, includes an official website listing over 480,000 covered works, allowing authors to verify their eligibility for compensation.

Financial details and obligation to destroy copies
Under the final agreement, each author will receive approximately $3,000 per affected work. In addition, Anthropic is required to destroy all pirated copies of the books in its archive. Some authors found the compensation too low and opted out of the settlement to pursue separate lawsuits against the company. The total $1.5 billion sum is unprecedented in an AI copyright case, setting a precedent for similar disputes.
Judge Martinez-Olguin's decision comes amid growing tension between creators and AI developers. While companies like Samsung establishes a robotics division explore new technological horizons, the Anthropic case demonstrates that innovation must respect copyright. Other giants, such as Insta360 which recently unveiled a photography robot, may face similar legal challenges if their training data includes protected works without authorization.
