Apple has filed a lawsuit against OpenAI, OpenAI hardware chief Tang Tan, and former Apple engineer Chang Liu, accusing them of stealing trade secrets tied to OpenAI’s hardware efforts. According to Apple’s complaint, Liu kept a company-issued MacBook and maintained access to internal cloud files after leaving Apple, and later joined OpenAI.
The lawsuit does not appear primarily aimed at immediately stopping OpenAI from shipping a device. Rather, Apple’s action targets the origin story: the company seeks to challenge the narrative around how OpenAI’s first hardware product was developed and to associate that development with alleged wrongdoing.
In consumer hardware development, engineers contribute more than technical skills. They bring tacit knowledge such as supplier relationships, lessons from failed prototypes, manufacturing trade-offs, and practical experience with bringing products to market. Apple’s claim is that OpenAI did not merely hire talent but also inherited — improperly, Apple alleges — that industrial memory.
The case raises broader questions about how technology companies handle employee mobility and protect proprietary information, and whether legal action is the appropriate tool to question the provenance of a new product. Apple contends the facts and evidence it will present could show that OpenAI’s hardware push was in part built on another company’s confidential information.
In short: Apple’s lawsuit against OpenAI, Tang Tan, and Chang Liu seeks to expose and legally contest the origins of OpenAI’s hardware work, even if it may not directly prevent the device from reaching the market.
