The law firm Troutman Pepper provides an analysis of two recent, conflicting court rulings in California that have added a new layer of complexity to the legal debate over "fair use" of copyrighted materials for training AI algorithms. These dueling decisions, issued by different courts within the state, have reached opposing conclusions on whether the unauthorized use of protected works to train generative AI systems qualifies as a permissible fair use under U.S. copyright law. This has created significant legal uncertainty for AI developers and content creators alike.

One ruling has leaned in favor of the AI developers, suggesting that the use of copyrighted data for training is transformative and thus likely to be considered fair use. This perspective emphasizes the innovative nature of the technology and its function in creating new, distinct outputs rather than simply reproducing the original works. In contrast, the other ruling has sided more with the rights holders, indicating that such large-scale, unauthorized copying for commercial purposes does not meet the criteria for fair use and directly harms the market for the original content. This judicial split highlights the lack of clear precedent and signals that the definitive legal answer on this critical issue will likely need to be resolved by higher courts, such as the Ninth Circuit or the Supreme Court.
