Penguin Random House Sues OpenAI Over 'Drache Kokosnuss'
Penguin Random House’s German publishing group has filed a lawsuit at the Landgericht München (Munich Regional Court) against OpenAI, alleging that ChatGPT infringes the copyrights of author‑illustrator Ingo Siegner and the publisher’s exclusive rights to the Der kleine Drache Kokosnuss book series. The complaint says simple prompts can produce recognizably similar text and illustrations, that ChatGPT supplies print‑ready manuscript suggestions and publishing instructions, and that Siegner’s works were likely used unlawfully for model training and now appear as memorized content. The publisher claims these outputs constitute unauthorized reproduction and public communication, violating rights held by the author, illustrator and CBJ (an imprint). The article notes a prior partial legal win by Germany’s Gema against OpenAI (Nov 2025) and cites a wave of related suits from other publishers and rights holders in 2026.
A major publisher suing OpenAI in Germany over alleged unlawful use of copyrighted books could set precedent for how generative AI vendors may use creative works for training and what outputs are permissible—affecting AI vendors, publishers, creators and any businesses that integrate generative models into creative workflows.

Penguin Random House Sues OpenAI Over 'Dragon Kokosnuss'
Penguin Random House has filed a lawsuit at the Munich Regional Court against OpenAI, alleging that ChatGPT infringes the copyrights of author-illustrator Ingo Siegner’s 'Der kleine Drache Kokosnuss' series. The publisher says ChatGPT can reproduce recognisable excerpts, generate illustrations closely resembling the dragon character, propose print-ready manuscripts with covers and blurbs, and provide step-by-step self-publishing instructions. Penguin Random House claims the works were improperly used to train OpenAI’s models and now appear memorized in outputs, violating the author’s and the publisher’s exclusive rights. The article references a prior partial court victory by German rights society Gema against OpenAI over song lyrics (November 2025) and notes an industry-wide wave of suits by publishers and music companies against AI firms.
Britannica and Merriam-Webster Sue OpenAI Over Copyright Violations
Encyclopedia Britannica and Merriam‑Webster have filed a lawsuit against OpenAI alleging large‑scale copyright infringement, claiming nearly 100,000 online articles owned by Britannica were scraped and used to train OpenAI’s large language models without permission. The complaint accuses OpenAI of producing outputs that reproduce full or partial verbatim content and of using Britannica’s articles in ChatGPT’s retrieval‑augmented generation (RAG) workflows. The suit also alleges Lanham Act violations for false attribution when the model hallucinates. The filing joins multiple publisher lawsuits against OpenAI; a similar Britannica suit against Perplexity is pending. The legal landscape over using copyrighted material as LLM training data remains unsettled.
Book Publishers Sue Google Over AI Training
A coalition of major publishers and authors — including Hachette Book Group, Cengage, Elsevier, novelist Scott Turow and S.C.R.I.B.E. — filed a class-action lawsuit against Google on July 14, 2026 in the U.S. District Court for the Southern District of New York. The complaint alleges Google trained its Gemini models on copyrighted books sourced from Google Books and titles uploaded to Google Play without permission, and removed or altered copyright information to conceal that use. Plaintiffs cite internal Google estimates of potential liabilities in the tens to hundreds of billions and say the practice displaces sales and undermines licensing markets. The filing is part of a broader wave of litigation over AI training data and follows publisher tactics such as crawler blocks and threats to delist from search.
