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.<ref name="cooldown" /><ref name="techstrong" /> 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.<ref name="cooldown" /><ref name="mlex" />
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.<ref name="afterdawn">Template:Cite web</ref><ref name="reuters">Template:Cite web</ref>
