Anthropic sued (again) for training on song lyrics and US government sides with OpenAI on issue of training LLMs on copyrighted material

What is the training of large models on copyrighted material (intellectual property)? Fair use or pirating? This answer to this question becomes very urgent.

The statutory damages asked for by plaintiffs could easily bankrupt Anthropic or any other company involved in model training.

I again strongly suggest to reform intellectual property rights. They are effective for way too many years! E.g. books and songs in the US, they "last for the life of the author plus an additional 70 years." (Google search) This is insane!!!

"In a lawsuit that The New York Times filed against OpenAI, the Trump administration has contributed a 20-page brief in defense of the ChatGPT maker’s unlicensed use of copyrighted material to train its LLMs.

“The United States has a strong interest in continuing to develop a robust and competitive artificial intelligence industry that sets the standard for the practice and procedure of AI use globally… As such, it is critical for the United States to ‘retain global leadership in artificial intelligence,’” the brief reads, referencing an executive order that President Donald Trump signed last year. ..."

"Sony Music Publishing and Warner Chappell Music sued Anthropic, along with CEO and co-founder Dario Amodei and co-founder Benjamin Mann, in the U.S. District Court for the Northern District of California, alleging Claude was trained on tens of thousands of copyrighted songs without permission. The complaint accuses Anthropic of torrenting pirated books from Library Genesis and Pirate Library Mirror, scraping lyrics from licensed sites like Musixmatch and LyricFind, and running a “destructive scanning” operation on physical books, citing findings already unsealed in the separate Bartz v. Anthropic authors’ case. The publishers seek statutory damages up to $150,000 per willfully infringed work plus up to $25,000 per removed copyright notice, destruction of infringing copies, and disclosure of Claude’s training data.
This is the fifth major music-industry suit against Anthropic, following actions from Universal Music Publishing Group, Concord, and ABKCO (over $3 billion), BMG, and Round Hill Music.
It also follows Anthropic’s $1.5 billion settlement with book authors over similar torrenting conduct, announced in 2025 and approved this year. The suit signals that music publishers are pushing for damages and licensing terms rather than accepting a one-time settlement. ..." (DataPoints)

Now Sony Music Publishing and Warner Chappell sue Anthropic in multi-billion dollar lawsuit: ‘One of the largest and most blatant ongoing thefts of intellectual property in history.’
