Apple Targets OpenAI in Trade Secret Lawsuit
Apple has filed a legal complaint in the U.S. District Court for the Northern District of California against OpenAI and two former Apple engineers, alleging a systematic misappropriation of trade secrets. The lawsuit claims that former employees Tang Yew Tan and Chang Liu transferred proprietary technical data to OpenAI to facilitate the development of the artificial intelligence company’s hardware initiatives.
Inside the Alleged Hardware Espionage
The lawsuit centers on the actions of Tang Yew Tan and Chang Liu, both of whom held significant roles within Apple’s hardware divisions. Tang Yew Tan served for 24 years at Apple, eventually becoming vice president of product design for the iPhone and Apple Watch. The complaint alleges that Tan used confidential internal codenames during recruitment interviews to extract sensitive information from candidates. Furthermore, the filing claims Tan requested that prospective hires bring physical hardware components, such as circuit boards and batteries, to interviews.
Chang Liu, previously a senior engineer on the iPhone team, is accused of unauthorized data extraction. The lawsuit states that before resigning from Apple, Liu downloaded dozens of files containing engineering presentations, technical specifications, and documentation for unreleased products onto a corporate computer that was never returned to the company.
Demands for Injunction and Damages
In its 41-page filing, Apple characterizes OpenAI’s hardware division as being built upon the foundation of these misappropriated secrets. The company asserts that it first contacted OpenAI regarding these concerns in February, but received no substantive response. Consequently, Apple is seeking a court order to force OpenAI to cease the use of any trade secrets, destroy all improperly obtained confidential material, and potentially redesign any products developed using that information. Apple has also requested a jury trial and unspecified financial damages.
A Strained Partnership Under Pressure
OpenAI has denied the allegations in an official statement, noting that the company has no interest in the trade secrets of other organizations. The company emphasized that its focus remains on developing technology designed to empower users globally.

This legal action creates a complex dynamic between the two firms. Currently, OpenAI remains a key partner for Apple, as its ChatGPT technology is integrated into Apple Intelligence and certain features within the Siri digital assistant. This lawsuit marks a shift toward direct litigation between two of the most influential entities in the artificial intelligence sector, signaling a potential strain on their ongoing collaborative efforts.
