On April 11, the Copyright Alliance, the Association of American Publishers (AAP), a group of Intellectual Property (IP) professors, the International Association of Scientific, Technical, and Medical Publishers, and others filed amicus briefs in the Kadrey v. Meta class-action lawsuit filed by a group of authors against the tech company over the unlicensed use of literary works to train the Llama AI model. The Copyright Alliance's amicus brief explains that Meta's unauthorized use of copyrighted literary works to train its Llama large language model is not for a transformative purpose, but even if it were, a finding of transformativeness does not control the fair use analysis. The brief goes on to distinguish the fair use cases Meta relies upon and makes clear that they have been significantly undermined by the U.S. Supreme Court's decision in Warhol v. Goldsmith.
