Major Publishers Seek to Join Lawsuit Accusing Google of Using Copyrighted Books to Train AI
GeokHub
San Francisco | Jan 15, 2026 — GeokHub Two major publishing companies have asked a U.S. federal court in California for permission to join an ongoing lawsuit against Google, escalating legal pressure on the tech giant over how it trains its artificial intelligence systems.
Hachette Book Group and Cengage Group, both leading global publishers, argue that Google unlawfully copied large volumes of copyrighted books and educational materials to develop its AI models, including its flagship systems.
Allegations of Large-Scale Copyright Infringement
In filings submitted to the court, the publishers claim Google built its AI capabilities by reproducing protected content without authorization, describing the alleged conduct as one of the most extensive copyright violations ever linked to AI development.
The publishers cite multiple examples of textbooks and literary works they say were used without consent, including titles from well-known authors, and are seeking financial damages on behalf of themselves and other affected rights holders.
Why Publishers Want to Join the Case
The lawsuit currently includes groups of writers and visual artists who accuse Google of misusing their work to train generative AI tools. The publishers argue their participation would strengthen the case, saying they are uniquely positioned to address technical, legal, and evidentiary questions related to publishing rights and licensing.
The Association of American Publishers, which represents major book publishers, said the industry’s involvement would help clarify how copyrighted materials should be treated in the age of AI.
Part of a Broader AI Legal Battle
The case is one of many high-profile legal actions worldwide as creators, publishers, and music companies challenge how technology firms collect and use data to train artificial intelligence systems.
Courts are increasingly being asked to determine whether AI training qualifies as fair use or requires licensing agreements — a question that could reshape how future AI models are built.
What Happens Next
The decision now rests with the federal judge overseeing the case, who will determine whether the publishers can formally join the lawsuit. If approved, their involvement could significantly raise the potential financial and legal stakes for Google.
Google has not publicly commented on the latest court filing.
