An author who opted out of the Bartz settlement sues Anthropic on his own in Massachusetts over the LibGen copy of his book
Daniel Gilbert, co-author of the 2007 book Hacking World of Warcraft, sued Anthropic on May 26, 2026, representing himself, and filed an amended complaint on July 7. He alleges the book is on the Bartz v. Anthropic Works List, that it was added to LibGen in 2011, before Anthropic's June 2021 LibGen download, and that Anthropic copied it and kept it in a permanent internal library. He says the settlement administrator confirmed his opt-out as timely. The complaint says the claim is for the downloading and retention, "not for model training." Because his publisher, Wiley, holds the copyright, he sues as a beneficial owner entitled to royalties, and alleges Wiley did not pursue the claim after he asked it to, which he says leaves any recovery to him under his publishing contract. He seeks statutory damages for willful infringement, an injunction and destruction of the copies. These are allegations; Anthropic has answered and denies infringement.

What the labels mean
Every item says what kind of source it rests on. A court ruling or order is the court's own statement. A company filing is what a defendant says about itself. A government filing is a statement by a government agency that is not a party to the case, such as a statement of interest; it is the government's position, not a ruling. An allegation is what a complaint or motion claims and has not been decided. Reported means press reporting we have not confirmed from the primary document. Summaries are our own; follow the links for the source.
This page is general information, not legal advice. An allegation is not a finding. Whether any of this matters for a particular work or claim is a question for a lawyer.
