Apple sues OpenAI and ex-staff over hardware trade secrets

The interesting part of Apple suing OpenAI is not the headline but the names on the complaint. According to CNBC's reporting, Apple filed Friday in the Northern District of California, accusing OpenAI of trade-secret misappropriation and breach of contract, and it named OpenAI's Chief Hardware Officer Tang Tan, a former Apple VP of product design who led iPhone and Apple Watch design before departing in February 2024, alongside Chang Liu, a senior systems electrical engineer of eight years who joined OpenAI in January 2026 and allegedly failed to return his Apple-issued laptop before downloading confidential hardware files.

Apple's framing is that the scheme was "at every level." The specifics in the complaint, as reported, are unusually granular. Tan is accused of using Apple's confidential project code names during OpenAI's recruiting process, asking job candidates to bring "actual parts" from Apple to interviews for "show and tell" sessions, and coaching departing Apple employees on how to evade the company's security procedures. Apple also alleges that OpenAI is asking hardware firms to carry out a metal finishing technique Apple invented, while misleading those partners into believing they had Apple's permission to do so.

Why it matters beyond the courtroom drama is the money already spent. OpenAI bought Jony Ive's startup IO Products, also named as a defendant, for $6.4 billion last year, and the whole point of that deal was consumer hardware. A trade-secret suit is one of the few tools that can actually slow a hardware roadmap because discovery drags on and injunctive relief can force redesigns. Apple and OpenAI are also still, on paper, partners on the ChatGPT integration inside Apple Intelligence, and Apple declined to comment on whether the lawsuit changes that.

The honest caveat is that this is Apple's version of the facts on day one. Trade-secret complaints almost always read damning; the defendants have not answered, no court has ruled, and the reporting does not describe the metal finishing technique in enough detail to judge how proprietary it really is. What the coverage does not give you yet is Apple's damages ask, whether it will seek a preliminary injunction, or whether the ChatGPT partnership survives.

If you are a competitor, the quieter opportunity is the talent market. Any Apple engineer OpenAI now cannot safely recruit is a person Google, Anthropic, Meta or a well-capitalised startup can. Lawsuits rarely stop people moving; they just change who they can move to.
