Authors Sue Meta One by One in New AI Copyright Cases Over Book Training

Hundreds of authors sue Meta in new copyright lawsuits over the use of their books to train its artificial intelligence models, choosing to bring individual cases rather than join a class action. The four complaints, led by novelists Jacqueline Winspear and Daniel José Older, writer Robert Sheard and author Tosca Reno, were filed on Monday, 19 October 2026, in the US District Court for the Northern District of California, Publishers Lunch and Bloomberg Law reported.

Publishers Lunch counted 231 authors across the four suits, while Bloomberg Law put the number who had signed on at around 300. Their lawyers say they plan to file individual cases for close to 1,000 more authors in the coming months.

Why Are Authors Suing Meta Individually?

Most copyright cases against AI companies have used the class-action mechanism, in which thousands of authors are grouped together and litigate as one. The new plaintiffs say that approach does not serve them. “Plaintiffs desire to retain full control of their case and avoid having their rights diluted by being swept into sprawling class-action settlements structured to resolve claims for pennies on the dollar,” the complaints state, according to Publishers Lunch.

The cases are being brought by the law firms Freedman Normand Friedland and Stris & Maher, Bloomberg Law said. Each author is seeking statutory damages, which under US copyright law can reach a maximum of $150,000 per infringed work.

What Do the Authors Allege?

The lawsuits make claims similar to earlier cases: that Meta downloaded hundreds of thousands of e-books from illegal online databases, known as shadow libraries, and used them to train its large language models without permission, Bloomberg Law reported.

The Winspear complaint goes further, according to a summary of the filing by the legal blog ChatGPT Is Eating the World. It targets both Meta’s older Llama models and its newer Muse models, and alleges that Meta’s scanning of physical books it lawfully owns, a programme that emerged in earlier litigation as “Project Vellum”, is also infringement.

• Court: US District Court for the Northern District of California, San Francisco.
• Lead plaintiffs: Jacqueline Winspear, Daniel José Older, Robert Sheard, Tosca Reno.
• Case numbers: 3:26-cv-12100, 3:26-cv-12115, 3:26-cv-12126 and 3:26-cv-12131.
• Models named: Llama and, in at least one complaint, Muse.
• Damages sought: statutory damages of up to $150,000 per work.
• Meta’s response: Meta did not immediately respond to Bloomberg Law’s request for comment.

How Have Similar AI Copyright Cases Gone?

Results so far have been mixed. The first class action brought by authors against Anthropic ended in a $1.5 billion settlement, which Bloomberg Law said would yield roughly $3,000 for each author who opted in. In Kadrey v. Meta, a proposed class action, the judge found that the plaintiffs had failed to show that Meta’s AI model was harming the market for their works.

In the Anthropic case, Judge William Alsup held that scanning lawfully purchased print books to create digital copies for training was fair use, while declining to extend that protection to copies acquired from shadow libraries, according to ChatGPT Is Eating the World. The new complaint’s challenge to physical-book scanning therefore tests an issue on which the only federal ruling so far has gone the AI company’s way.

What Is Meta’s Defence Likely to Be?

AI companies, including Meta, have argued that their use of books is protected by the fair use doctrine because they transform the copies into an entirely new technology, Bloomberg Law reported. The blog noted that the new cases are likely to be assigned to Judge Vince Chhabria, who presides over the related author and publisher lawsuits against Meta.

Why Does This Matter for Authors and Publishers?

If the strategy succeeds, individual suits could put far more financial pressure on AI developers than class settlements, because statutory damages are calculated per work and each author controls their own claim. It could also make litigation slower and more complex for courts and companies alike.

The cases add to a crowded legal landscape. By one unofficial count from ChatGPT Is Eating the World, Meta faces 17 copyright lawsuits related to its AI models, and the Winspear suit is the 149th copyright case against an AI company in the US. Pressure is building elsewhere too: publishers in South Korea have urged a copyright trust body to act against what they call AI “book theft”, the Seoul Economic Daily reported.

What to Watch

• More filings: whether the promised suits for close to 1,000 more authors arrive.
• Case assignment: whether the new cases are related to Kadrey v. Meta before Judge Chhabria.
• Project Vellum: how the court treats the claim over scanning physical books.
• Meta’s response: any motion to dismiss or to consolidate the individual suits.
• Other AI companies: whether authors take the same individual approach against other developers.
