Anthropic sued 2x in 1 day. Shadow Library Strategy strikes again. Total all copyright suits v. AI companies hits 93.

The Shadow Library Strategy is back. Two new copyright lawsuits were filed against Anthropic.

The first, Chicken Soup for the Soul v. Anthropic, was filed by the same Stris & Maher law firm that already filed a similar lawsuit against the same defendants: Anthropic, Google, OpenAI, Meta, xAI, Perplexity, Apple, and NVIDIA. Docket is here.

I call this the omnibus copyright lawsuit against the entire U.S. AI industry. The lawyers have already stated that the Chicken Soup for the Soul lawsuit is related to Cambronne v. Anthropic, originally filed by book author John Carreyrou (who doesn’t own the copyight to his books, his company Cambronne does).

Following motion to dismiss, John Carreyrou substitutes his company Cambronne as Plaintiff, plus adds NVIDIA and Apple to the omnibus copyright suit v. the U.S. AI industry

The second lawsuit is BMG Rights Management v. Anthropic, a case involving copyrighted musical works. It is quite similar to the Concord Music v. Anthropic I and Concord Music II lawsuits now before Judge Eumi Lee.

Anthropic scores minor win as Judge Lee deems Concord Music v. Anthropic II (alleged use of shadow libraries) is related to Concord Music v. Anthropic I. II gets reassigned to Judge Lee
