A group of book publishers has filed a lawsuit against Google, accusing the company of using copyrighted books without permission to train its Gemini artificial intelligence models. The plaintiffs—Hachette Book Group, Cengage Learning, and Elsevier—also include author Scott Turow, according to reporting that the case is filed in federal court in New York. The publishers allege that Google built Gemini using “millions” of copyrighted books and characterize the alleged conduct as among the most prolific infringements of copyrighted materials in history. The dispute centers on whether Google’s AI training processes involve unlawful copying or other copyright violations when using large quantities of book content. Separate coverage also notes that the lawsuit arrives as some web publishers consider changing how they distribute or rely on Google Search services, reflecting broader tensions between content industries and major technology platforms. Google has not been described as conceding wrongdoing in the cited reporting. The legal standoff is ongoing, and the allegations have yet to be tested in court.
