A US court analyzed whether the use of copyrighted books to train Anthropic's Claude model qualifies as fair use under copyright law. Applying relevant precedents such as Google Books and Texaco, the court considers that the training process of large language models is likely transformative, which favors fair use protection as long as the model's outputs do not reproduce infringing material or substitute for the original works in the market.
The plaintiff authors argue that even format changes or repackaging of content could infringe their rights, but the court emphasizes the importance of case law and the public benefit derived from transformative uses for research, innovation, and access to knowledge. In this case, the first factor of the fair use analysis, concerning the purpose and character of the use, is clearly favorable to Anthropic, while other factors such as the amount and the effect on the market remain under examination.
The implications for companies and developers are clear: training models with protected material requires evaluating licenses, applying technical and procedural safeguards to minimize infringement risks, and documenting the transformative nature of the use. Measures such as output filtering, responsible data sampling, annotation, and the inclusion of licensed data help mitigate legal and reputational risks.
