A judge considers training AI with complete books reasonably necessary
A court determined that Anthropic's use of complete books to train its Claude models may be legitimate use under the fair use doctrine due to the transformative nature of the result, the fact that the output does not compete with the original texts, and the enormous amount of material needed to obtain useful models. However, the court ruled against fair use when pirated copies were included in an internal digital library, deeming that scope of copying unjustified.
The ruling is based on an assessment of the classic fair use factors: the purpose and character of the use, the nature of the protected material, the amount and substantiality of what was copied, and the effect on the potential market. The court highlighted that training language models produces transformative results that do not replace the original books and that, in many cases, processing complete texts is reasonably necessary to learn linguistic and conceptual patterns. However, keeping pirated copies accessible and without legitimate commercial justification was considered unjustified harm to rights holders.
The practical consequences for technology companies and AI developers are clear: responsible data curation, license compliance, and transparency in processing chains are essential. The ruling underscores the difference between extracting knowledge from texts to improve models and retaining or redistributing protected material without permission.
