Plaintiffs counsel in Doe v. GitHub, which is widely considered to be the first lawsuit to challenge companies' use of copyrighted materials to train generative artificial intelligence models, on Tuesday filed a new petition to the U.S. Court of Appeals for the Ninth Circuit.

The appeal questions whether liability under §1202(b) of the Digital Millennium Copyright Act is limited to the "removal or alteration of Copyright Management Information from an identical copy of a work." It was filed by Joseph Saveri of Joseph Saveri Law Firm, Matthew Butterick of Butterick Law and Maxwell V. Pritt and Jesse Panuccio of Boies Schiller Flexner.
