- Decision rejects transformative use defense for commercial AI model development on copyrighted content.
- Thomson Reuters alleged defendant scraped its legal database to build competing AI products.

- Ruling creates new liability precedent for AI companies using unlicensed third-party training data.
- Legal analysts predict accelerated licensing deals between content owners and AI developers.
The story
A U.S. federal court ruled that training artificial intelligence models on copyrighted legal data does not constitute fair use, handing a significant victory to Thomson Reuters in its litigation against an AI developer. The decision establishes that commercial AI training on proprietary content may require licensing, rejecting the argument that such use is sufficiently transformative under copyright law. Legal experts state this ruling creates substantial liability exposure for AI companies relying on unlicensed third-party data for model development. Thomson Reuters alleged the defendant unlawfully scraped and utilized its legal database to build competing products. The defendant has denied wrongdoing and signaled intent to appeal the verdict. This marks one of the first major judicial determinations specifically addressing AI training practices under U.S. copyright statutes. Industry stakeholders anticipate the ruling will accelerate licensing negotiations between content owners and AI developers seeking to mitigate litigation risks.
