Hachette, Elsevier, Cengage, and novelist Scott Turow say Google's Gemini generates summaries and explanations that rival the books and journals it was trained on, and seek damages and an injunction.
A federal class action filed in New York on Friday makes a claim earlier AI-training copyright lawsuits have not. Hachette Book Group, Cengage Learning, Elsevier, and author Scott Turow argue that Google's Gemini, the search company's flagship AI assistant, now produces summaries and textbook-style explanations that compete with the books and journal articles it was trained on. They say Google built a multibillion-dollar business while sidestepping a market publishers had formed to license content to AI labs.
The complaint was filed in the U.S. District Court for the Southern District of New York, docket 1:26-cv-05870. It alleges Google copied millions of books and journal articles without permission, drawing from Google Books, online libraries, and "allegedly" pirated websites, according to TheWrap.
What separates the new case from the wave of AI-training suits it joins is the second-order argument. Earlier complaints, including The New York Times' lawsuit against OpenAI, have focused on whether models were trained on copyrighted material without a license. The Hachette complaint goes further. Plaintiffs argue Gemini's outputs are not just derivatives of the works it learned from, but substitutes for them. When a user asks Gemini to summarize a chapter or explain a concept from a textbook, the complaint says, Google's product is doing the job the original was bought to do.
That shift converts a copyright dispute over copying into a competition dispute over substitution. A finding for the plaintiffs would not only expose Google to damages for past copying. It would constrain what Gemini and similar products are allowed to generate, and would hand publishers a legal basis to demand licensing for any output that could plausibly replace a copyrighted work.
The complaint also targets an emerging licensing market. Publishers including Hachette had begun negotiating content deals with AI companies, the same kind of arrangement OpenAI struck with the Financial Times and others, that would let labs train on books and journals in exchange for payment. The plaintiffs argue Google built Gemini while bypassing those talks, according to Hachette's announcement of the suit. "Multibillion-dollar AI business" and "one of the most prolific infringements of copyrighted materials in history" are the plaintiffs' characterizations, not adjudicated findings.
The case joins a wave of similar AI-training copyright suits that have accumulated in federal courts. The New York Times sued OpenAI and Microsoft in late 2023, image-generator suits against Stability AI, Midjourney, and others followed, and the new filing adds Google to the list of defendants, Publishers Weekly reports.
Publishers are not neutral stewards of the public's reading life. They are businesses with shareholders and quarterly results, and the same firms now arguing that Gemini substitutes for their books were, a decade ago, fighting authors over e-book royalties. The licensing market they describe is one in which they would be paid twice for the same work: once by readers, once by AI labs. The complaint does not address that tension, and a court asked to police substitution will eventually have to weigh it.
The Elsevier and Cengage plaintiffs add a second front. Elsevier publishes flagship scientific journals including The Lancet and Cell, and Cengage's textbooks dominate undergraduate classrooms. If Gemini can explain a chemistry concept in a way that replaces the relevant chapter, the affected market is not just trade fiction but the high-margin course-material and journal-licensing business that funds a large share of academic publishing, CNET notes.
Google did not immediately respond to a request for comment, TheWrap reported. The complaint seeks damages and a court order blocking further alleged infringement, which, if granted in the plaintiffs' preferred form, would limit what Gemini is allowed to output as much as what it is allowed to ingest, Adweek reports.
The next markers to watch are Google's first filing. A motion to dismiss is the standard opening move in this kind of suit, and the more interesting question is whether the court treats the substitution theory as a separate cause of action, or folds it back into the traditional copying claim.
