Apple Sues OpenAI for Trade Secret Theft, Names Chief Hardware Officer Tang Yew Tan as Defendant

Apple sued OpenAI and two former employees on Friday, July 10, 2026, alleging a deliberate and systematic campaign to steal confidential hardware designs, supplier data, and engineering files — a dramatic escalation that pits the iPhone maker against its own AI partner just as OpenAI pushes into physical devices. The suit, confirmed by court records, names OpenAI’s chief hardware officer Tang Yew Tan and former Apple employee Chang Liu as individual defendants alongside the AI company itself, according to Reuters.

This is not a case about a couple of rogue engineers. Apple’s complaint paints a picture of coordinated corporate raiding — the kind of allegation that implicates institutional decision-making, not just individual misconduct. Tang, before he left for OpenAI, allegedly emailed himself confidential information about Apple’s suppliers. And since? He’s been directing job candidates still on Apple’s payroll, according to details surfaced in the lawsuit text — an active, ongoing effort to poach talent that knows the company’s hardware operations from the inside. Chang Liu, the second named defendant, is also accused of walking off with proprietary information before joining OpenAI. What exactly Liu allegedly took is fuzzier in the public filing, but the overall accusation is sweeping: that OpenAI orchestrated a systematic effort to strip Apple of trade secrets relevant to building consumer hardware (CNBC).

The ‘Coaching’ Allegation

Apple’s most striking claim goes further still. The suit alleges OpenAI did not merely benefit from what departing employees happened to carry out the door — it actively coached them on how to circumvent Apple’s own security and exit processes before they left. Prove that, and the case leaps from routine employee poaching into something closer to a conspiracy, implicating OpenAI’s processes and potentially its leadership in the alleged theft. According to Axios, the lawsuit accuses OpenAI of deliberately and systematically soliciting and stealing confidential information — not passively receiving it.

The Hardware Competition Angle

The strategic motive is obvious. OpenAI is building hardware devices, which drops the AI company straight into Apple’s turf — a consumer electronics market where Apple has spent two decades constructing one of the most tightly controlled supply chains in manufacturing history. The alleged stolen intellectual property — supplier relationships, hardware designs, engineering files — would be a shortcut past years of painstaking development work, the very work that has historically guarded Apple’s margins and product differentiation. As The Wall Street Journal reports, the lawsuit specifically accuses OpenAI and Tang Tan of stealing trade secrets to develop competing devices, making the hardware ambitions the explicit motive in Apple’s legal theory.

The Partnership Paradox

Then there’s the backdrop, which makes the whole thing extraordinary. Apple and OpenAI maintain a public partnership that integrates ChatGPT into Apple’s iOS ecosystem — a deal announced with considerable fanfare, positioned as a flagship AI feature for iPhone users. This lawsuit does not quietly coexist with that arrangement. It is a direct accusation that one partner has been systematically robbing the other, even as the two keep collaborating in public. Whether Apple intends to unwind or renegotiate that partnership in light of the litigation is an open question, but the suit itself represents a profound rupture in what had been presented as a high-profile alliance.

Legal and Industry Implications

The legal road ahead is steep. Trade secret litigation typically requires the plaintiff to demonstrate that the information at issue was genuinely confidential, that reasonable measures were taken to protect it, and that the defendants acquired or used it improperly. Apple’s allegation that OpenAI coached employees to evade security processes — if the evidence backs it up — could prove decisive, because it cuts to the core question of intent and the adequacy of safeguards. Remedies in such cases can include injunctive relief barring use of the disputed information, monetary damages, and in some instances punitive damages if willful misconduct is established. Apple has not publicly specified the exact remedies it is seeking, and the court in which the suit was filed has not been detailed in the initial reporting.

The case lands amid a broader pattern, too. As AI companies race to move beyond software and into physical products, the boundaries between tech platforms are collapsing — and so are the informal norms that once governed how talent and intellectual property moved between them. OpenAI’s reported hardware ambitions, widely understood to involve former Apple design chief Jony Ive, put the company on a collision course with Apple regardless of this lawsuit. The litigation simply makes that collision formal.

What’s Next

No public statement from OpenAI had been issued as of the initial filings. The case is now in court, confirmed by records. Next milestones to watch: OpenAI’s formal response, any preliminary injunction motions Apple may file to block use of the disputed information, and whether the ChatGPT integration partnership survives the legal fallout.
