Apple Sues OpenAI for Trade Secrets — Seeks Hardware Ban

Apple just launched the most aggressive legal assault on a competitor's hardware ambitions in a decade — and it's aimed squarely at OpenAI's first consumer device before it ever reaches a customer.

On July 10, 2026, Apple filed a federal trade-secret lawsuit in the Northern District of California alleging that OpenAI engaged in a "systematic effort to acquire, retain, and use Apple's trade secrets" through a campaign of targeted hiring and confidential-information extraction. The complaint names specific individuals, specific documents, and a specific manufacturing partner — it reads less like a fishing expedition and more like a case Apple has been building for months. The remedy Apple is seeking is equally pointed: an injunction that would effectively halt OpenAI's hardware division.

What happened — Apple's trade-secret allegations

The complaint centers on two key individuals:

Tang Tan, OpenAI's chief hardware officer, spent 24 years at Apple as VP of product design for iPhone and Apple Watch. Apple alleges that before leaving, Tan emailed Apple supplier details to himself; during OpenAI recruiting interviews, he asked Apple employees for confidential information about unannounced products; and he coached departing Apple staffers on how to evade the company's security procedures.

Chang Liu, who spent 8 years at Apple as a senior systems electrical engineer, is accused of using an Apple-issued laptop after leaving to download "dozens of Apple's confidential hardware-related files, including voluminous, detailed information about unreleased products, engineering presentations, technical specifications, and proprietary project data." Liu allegedly instructed a former colleague on how to copy confidential files and "avoid trouble" with Apple's security team ahead of her joining OpenAI — suggesting they use Line Messenger to avoid detection.

Apple claims more than 400 former Apple staffers now work at OpenAI — a number that transforms this from an individual-misconduct case into what Apple portrays as a deliberate talent-acquisition strategy. The complaint alleges OpenAI told Apple employees to bring "CAD/design artifacts" and "prototypes" to job interviews, and advised departing staffers to let OpenAI know if Apple personnel "ask you to sign anything."

The lawsuit also names io Products — Jony Ive's hardware startup, acquired by OpenAI in 2025 for $6.5 billion — and describes an incident where OpenAI allegedly misled a shared manufacturing partner into performing Apple's proprietary metal-finishing technique by falsely claiming it had Apple's permission.

Apple first reached out to OpenAI in February 2026 to raise concerns. "OpenAI never responded," the complaint states.

OpenAI spokesperson Drew Pusateri responded minimally: "We have no interest in other companies' trade secrets. We remain focused on building innovative technology that empowers people everywhere."

Why it matters

This isn't a routine IP dispute — three dimensions make it significant:

1. Apple is trying to kill a competitor before it ships. Industry analyst Ming-Chi Kuo has reported that OpenAI's first hardware product could be an AI phone that replaces apps with agents — a direct threat to the iPhone, Apple's most important product. Apple's complaint language is unusually blunt: "OpenAI's nascent hardware business now rests on the shakiest of foundations, rotten to its core by its illegal reliance on misappropriated trade secrets." This isn't legal boilerplate; it's a statement of intent.

2. The lawsuit exposes OpenAI's hardware strategy in detail. The complaint confirms that OpenAI's hardware push isn't a side project — it's a fully-resourced effort with a chief hardware officer, an acquired design studio, and a systematic recruiting pipeline targeting Apple's most experienced hardware engineers.

3. OpenAI's IPO timeline gets a new risk vector. Coming off the April release of GPT-5.5, OpenAI filed confidentially for an IPO in June 2026 (OpenAI, 2026). A federal trade-secret lawsuit from Apple — seeking an injunction that could halt a major business line — is the kind of unresolved legal risk that makes institutional investors demand a discount, or pause entirely.

What changes for you

FAQ

Is Apple suing over AI models or hardware? Hardware exclusively. The complaint targets OpenAI's consumer-device ambitions — not ChatGPT, not GPT models, not API access. Apple's concern is competition for the iPhone, not the AI software market.

What happens next? The case is in its earliest stages. Apple will seek discovery to learn the full extent of OpenAI's use of its trade secrets. OpenAI has not yet filed a formal response. A preliminary injunction hearing could come within months, and it will be the first real test of whether Apple's allegations hold up.

Could this actually stop OpenAI's hardware division? It's possible. Trade-secret injunctions are rare but not unprecedented. If discovery surfaces evidence that OpenAI's hardware development is substantially built on misappropriated Apple information, a court could bar the use of that knowledge — which, for a hardware product in development, can be functionally equivalent to a shutdown.

Does io Products / Jony Ive face personal liability? No. The complaint names io Products as a corporate entity but does not name Ive individually.
