Anthropic Says Its Chatbot AI Training Is a Fair Use of Books

Anthropic has asked a California federal court to dismiss a lawsuit filed by authors who claim the company used their copyrighted books without permission to train its AI chatbot, Claude. The company contends that its method is transformative because it repurposes the text to build new technology rather than reproduce the original content. This legal request, noted as of March 28, 2025, highlights the growing debate over fair use in AI training data.

Recent cases in the tech industry have similarly tested the boundaries of copyright law. For example, on March 26, 2025, a California judge denied a preliminary injunction in a copyright case brought by music publishers, reinforcing the argument that certain AI training methods do not infringe on copyrights when they create new forms of technology. Anthropic’s case may thus become a pivotal reference point for future disputes over AI and copyright in various creative sectors.
