Apple has sued OpenAI in federal court, saying in a complaint filed in the U.S. District Court for the Northern District of California that OpenAI, io Products, Tang Tan, and Chang Liu were involved in efforts to get hold of trade secrets tied to unreleased Apple hardware. In the filing, Apple asks for damages, a jury trial, and court orders that would block any use of its confidential materials and force their return or destruction. Apple says the information at issue includes product details, parts, drawings, engineering presentations, and technical specifications for devices that haven’t been announced, and argues this wasn’t an isolated mistake but part of a broader recruiting and hardware effort.
Apple says the internal investigation began after Chang Liu allegedly didn’t return a company laptop in January 2026. In the complaint, Apple claims Liu later exploited an unknown security flaw to keep accessing Apple systems after joining OpenAI and downloaded confidential files.
The complaint also says Tang Tan asked candidates to bring “actual parts” to interviews. Apple points out that OpenAI has hired more than 400 former Apple employees, while OpenAI rejected the accusations in a statement, saying it has “no interest in other companies’ trade secrets.”
The lawsuit marks a clear break after Apple and OpenAI had been working together on ChatGPT features for the iPhone. It also lands as OpenAI moves deeper into hardware following its acquisition of Jony Ive’s io Products in a deal reportedly worth about $6.5 billion, with smart speakers and smart glasses having surfaced in earlier reports as products under consideration.
If you keep a close eye on Apple and OpenAI, this is a case to watch. You can follow it in the Northern District of California as the early-stage proceedings start to unfold.
