As we close out 2025, the copyright lawsuits against AI companies continue unabated. We have now hit Copyright Lawsuit No. 68.
It’s the 30th copyright lawsuit filed in 2025 against AI companies.
LYON V. ADOBE
Earlier this week, book author Elizabeth Lyon, who writes about how to get published, sued Adobe for training its slim language model (SLM) allegedly using pirated copies of books from shadow libraries, including the SlimPajama dataset. Lyon seeks a class action.
The Complaint alleges: “The SlimPajama dataset is a training dataset assembled and published by Cerebras Systems Inc. (“Cerebras”) that is directly derived from Together Computer, Inc.’s (TogetherAI”) RedPajama dataset. Notably, Cerebras describes its SlimPajama dataset as a copied, cleaned, and deduplicated version of Together AI’s RedPajama dataset.”
The Complaint alleges one count for direct copyright infringement by Adobe. It was filed in the Northern District of California and is assigned, for now, to Magistrate Judge Nathanael Cousins.
