AI industry horrified to face largest copyright class action ever certified; Ars Technica, August 8, 2025

ASHLEY BELANGER, Ars Technica ; AI industry horrified to face largest copyright class action ever certified

"AI industry groups are urging an appeals court to block what they say is the largest copyright class action ever certified. They've warned that a single lawsuit raised by three authors over Anthropic's AI training now threatens to "financially ruin" the entire AI industry if up to 7 million claimants end up joining the litigation and forcing a settlement.

Last week, Anthropic petitioned to appeal the class certification, urging the court to weigh questions that the district court judge, William Alsup, seemingly did not. Alsup allegedly failed to conduct a "rigorous analysis" of the potential class and instead based his judgment on his "50 years" of experience, Anthropic said.

If the appeals court denies the petition, Anthropic argued, the emerging company may be doomed. As Anthropic argued, it now "faces hundreds of billions of dollars in potential damages liability at trial in four months" based on a class certification rushed at "warp speed" that involves "up to seven million potential claimants, whose works span a century of publishing history," each possibly triggering a $150,000 fine.

Confronted with such extreme potential damages, Anthropic may lose its rights to raise valid defenses of its AI training, deciding it would be more prudent to settle, the company argued. And that could set an alarming precedent, considering all the other lawsuits generative AI (GenAI) companies face over training on copyrighted materials, Anthropic argued."

Judge Rules Class Action Suit Against Anthropic Can Proceed; Publishers Weekly, July 18, 2025

"In a major victory for authors, U.S. District Judge William Alsup ruled July 17 that three writers suing Anthropic for copyright infringement can represent all other authors whose books the AI company allegedly pirated to train its AI model as part of a class action lawsuit.

In late June, Alsup of the Northern District of California, ruled in Bartz v. Anthropic that the AI company's training of its Claude LLMs on authors' works was "exceedingly transformative," and therefore protected by fair use. However, Alsup also determined that the company's practice of downloading pirated books from sites including Books3, Library Genesis, and Pirate Library Mirror (PiLiMi) to build a permanent digital library was not covered by fair use.

Alsup’s most recent ruling follows an amended complaint from the authors looking to certify classes of copyright owners in a “Pirated Books Class” and in a “Scanned Books Class.” In his decision, Alsup certified only a LibGen and PiLiMi Pirated Books Class, writing that “this class is limited to actual or beneficial owners of timely registered copyrights in ISBN/ASIN-bearing books downloaded by Anthropic from these two pirate libraries.”

Alsup stressed that “the class is not limited to authors or author-like entities,” explaining that “a key point is to cover everyone who owns the specific copyright interest in play, the right to make copies, either as the actual or as the beneficial owner.” Later in his decision, Alsup makes it clear who is covered by the ruling: “A beneficial owner...is someone like an author who receives royalties from any publisher’s revenues or recoveries from the right to make copies. Yes, the legal owner might be the publisher but the author has a definite stake in the royalties, so the author has standing to sue. And, each stands to benefit from the copyright enforcement at the core of our case however they then divide the benefit.”"

"Alphabet's Google (GOOGL.O) was accused in a proposed class action lawsuit on Tuesday of misusing vast amounts of personal information and copyrighted material to train its artificial intelligence systems.

The complaint, filed in San Francisco federal court by eight individuals seeking to represent millions of internet users and copyright holders, said Google's unauthorized scraping of data from websites violated their privacy and property rights."
