Two groundbreaking decisions from the Northern District of California—Kadrey v. Meta Platforms, Inc. and Bartz v. Anthropic PBC—shed light on how courts are approaching the use of copyrighted materials in training large language models (LLMs). Both cases involved authors alleging copyright infringement based on the use of their books to train generative AI models, and both courts held that use of the copyrighted materials to train the AI models was transformative. The court in Anthropic held, however, that copying pirated books constitutes copyright infringement and the transformative nature of the use did not rescue such infringement. Conversely, the Meta court held that copying from pirate sites to train AI is fair use, but only because the plaintiffs failed to submit evidence of market harm, which the court believed to be the most relevant factor. As such, while use of copyrighted works to train AI may be fair use, copying works without permission carries the risk of infringement. Read the full Alert on the Duane Morris website.
