Penguin Random House deployed a new copyright notice in all new and reprinted books, stating that no part of each book may be used to train AI systems. This change, first reported in October 2024, applies globally across all PRH imprints.

The updated copyright text reads: 'No part of this book may be used or reproduced in any manner for the purpose of training artificial intelligence technologies or systems.' PRH also added language to its books published in EU markets that expressly reserves its works from the text and data mining exception provided under European Union copyright law. This is a legal and policy measure rather than a technical AI system, but it directly governs how PRH's content may interact with AI pipelines. The company has stated it 'maintains that the unauthorized use of copyrighted content to train generative AI models constitutes copyright infringement.'
