News Penguin Random House v OpenAI 2026
April 6, 2026 — Penguin Random House Germany has filed a copyright infringement lawsuit against OpenAI's Ireland-based European subsidiary in a German court, alleging that ChatGPT reproduced content virtually indistinguishable from the Coconut the Little Dragon children's book series by Ingo Siegner.[1][2][3]
Overview
PRH claims that when prompted to create a similar story, ChatGPT generated text and images "virtually indistinguishable from the original," due to OpenAI's "memorization" of training data.[1][2] The case was filed in Germany, likely at the Munich Regional Court, following a November 2025 ruling by that court that ChatGPT violated German copyright by reproducing musicians' songs.[1][3]
Context
OpenAI has faced a steady accumulation of copyright lawsuits from publishers, authors, and media organizations. Prior to this case, OpenAI was already defending itself against suits from Encyclopedia Britannica, Merriam-World, and a group of authors whose case survived a motion to dismiss.[4][5]
