This case tracker monitors key U.S. litigation that raises copyright (and copyright adjacent) issues related to the creation and use of generative AI. These issues can have a significant impact across the AI value chain, from content creators to those providing datasets, models, or AI solutions, and further still to the downstream uses of AI solutions (and AI outputs).
We monitor key copyright issues raised by the proliferation of generative AI technology by tracking key pending litigation. Each case has a page devoted to an overview of the lawsuit, a repository of key filings that address substantive legal issues, and a running summary of these filings.
This case tracker is in archive mode. For questions or feedback, please reach out to our editor, Theresa M. Weisenberger, and contributor, Harrison A. Enright.
