Apple isn’t just suing two ex-employees. It is watching everyone who jumped ship to OpenAI.
Reports indicate the tech giant sent legal preservation letters to around 40 former Apple employees currently working at the AI lab. These letters are a formal command: keep everything. Any email, file, or slack message related to Apple must be saved. It’s a warning shot, loud and clear.
Why is Apple targeting former OpenAI employees?
This isn’t about friendship. It’s about hardware.
Apple recently filed a lawsuit accusing two key former staff members—Tang Yew Tan, the former VP of Product Design, and Chang Liu, an iPhone engineer—of stealing trade secrets. Apple claims these individuals used confidential internal information to help build OpenAI’s new consumer hardware.
Tan is now OpenAI’s Chief Hardware Officer. Liu joined the firm earlier this year. Apple calls these two the tip of an iceberg. The lawsuit suggests the leak runs deeper than two people.
“Just the tip of the iceberg”
That’s how Apple described the scale of the alleged data breach in court documents. If the rumors are right, there are 400 former Apple employees now working at OpenAI. That’s a massive talent drain. But why serve legal letters to only 40?
The strategy seems twofold. First, it freezes their ability to destroy evidence before discovery begins. Second, it creates psychological pressure. You know you are being watched.
OpenAI has denied all allegations, of course. They call it baseless. But the litigation game has changed. The scope of the fight is expanding from two individuals to potentially dozens of insiders who knew too much about the inner workings of Apple hardware design.
Who are the key players in the Apple OpenAI lawsuit?
The faces matter. You need to know who walked out the door with Apple’s secrets, or at least, the keys to the castle.
- Tang Yew Tan : Former Vice President of Product Design at Apple. He now leads hardware strategy at OpenAI as Chief Hardware Officer. His access level was high. His knowledge of the Mac ecosystem and device form factors is likely the prize Apple thinks it lost.
- Chang Liu : An engineer who worked on the iPhone. She left for OpenAI earlier this year. Her specific technical insights into smartphone construction could be valuable for AI-driven device optimization or new gadget designs.
These aren’t interns. They are veterans with deep institutional memory. Apple argues this memory shouldn’t have traveled across town in a LinkedIn migration.
The 40 letter recipients remain unnamed in public reports, but their selection likely points to other areas where hardware knowledge intersects with AI ambitions. Maybe camera sensors? Thermal management? Battery tech? The specific targets will likely emerge only in discovery, assuming these former workers comply.
OpenAI stands firm, but the landscape has shifted. It used to be about talent acquisition. Now, it’s a liability minefield. Every ex-Apple hire comes with a shadow of potential litigation.
Apple knows its brand relies on hardware perfection. If OpenAI is cloning that DNA using stolen notes, it threatens the core identity of the Cupertino company. The letters are just the first move. There are 360 more former employees left in the open. Apple could decide to widen the net next month.
Or it could stop here. The silence is the loudest part of the strategy.
