Apple Sues OpenAI For Systematically Recruiting Employees to Steal Secrets

Apple’s lawsuit against OpenAI reads less like a typical trade secrets complaint and more like a corporate espionage thriller, complete with smuggled hardware components, a leaked internal security document, and an employee who texted a colleague to celebrate accidentally keeping access to Apple’s systems.

The actual claim, filed in the Northern District of California, is that OpenAI systematically directed incoming hires to extract confidential information before leaving Apple, and that two former Apple employees coordinated that effort from inside OpenAI.

How OpenAI’s Hardware Team Allegedly Ran the Operation

Apple names Tang Tan, its former head of product design who later became OpenAI’s hardware lead, as the central figure. According to the lawsuit, Tan used his detailed knowledge of Apple’s internal departure procedures to coach new OpenAI recruits on how to stay at Apple as long as possible without revealing where they were going. He allegedly retained an internal Apple document marked “Need to Know” that described security protocols for departing employees, then shared it with incoming OpenAI hires before they gave notice, effectively teaching them how to avoid triggering the exact safeguards Apple had built to prevent this.

The other named defendant, Chang Liu, allegedly kept an Apple-issued laptop after leaving the company and exploited a vulnerability to download dozens of confidential documents while already employed at OpenAI. He also maintained contact with a current Apple employee, Yu-Ting Peng, who continued feeding him updates on Apple projects, vendor decisions, and engineering details. When Liu discovered his network access had not been revoked, he texted Peng: “LOL, I found out I can access the [network storage], so funny.”

Apple says the pattern extended to job interviews themselves. Tan allegedly instructed one candidate to bring physical hardware components, including batteries, SIPs, and logic boards, to her OpenAI interview. Apple claims this was not a one-off request.

Apple Supplier Relationships Were Apparently on the Table Too

The lawsuit includes a detail that goes beyond personnel and documents. Apple alleges OpenAI used confidential supplier information to approach Apple’s own hardware vendors, and in at least one case tricked a supplier into applying a specific trade secret metal-finishing technique to an OpenAI device by falsely claiming Apple had given permission. That allegation, if it holds up, extends the liability chain well beyond the two named individuals and into OpenAI’s procurement and hardware development operations directly.

Apple’s statement says it first tried to contact OpenAI in February after uncovering initial evidence, and that OpenAI did not respond. The lawsuit followed. The complaint describes the situation as “the tip of the iceberg,” arguing Apple cannot fully assess the damage because it lacks visibility into what has happened inside OpenAI’s walls.

What This Lawsuit Actually Signals About OpenAI’s Hardware Ambitions

OpenAI has been publicly working toward its own hardware device, a project that gained visibility after the company hired Tan away from Apple. The irony of that hire is now the core of this lawsuit. Apple’s argument is not just that individual employees misbehaved but that OpenAI leadership created a structure where this kind of extraction was normalized and encouraged. The phrase “rotten to its core” appears in the actual complaint, which is unusually pointed language for a legal filing.

For Apple, the strategic concern is real regardless of how the lawsuit resolves. If OpenAI has been building its hardware roadmap using Apple’s supplier relationships and manufacturing knowledge, the competitive damage may already be done. Litigation can award damages and injunctions, but it cannot un-share information that has already shaped product development decisions.

For most Apple users, this lawsuit has no immediate practical effect. No products are recalled, no services are changing, and no security vulnerability affects your devices. The case is worth watching if you care about how Apple’s unannounced hardware pipeline might have been exposed, but there is nothing to do or update in response to today’s filing.
