Apple sues OpenAI for trade secret theft in thermonuclear escalation over hardware talent

Apple Sues OpenAI for Trade Secret Theft Over Hardware Talent War

Apple has sued OpenAI, alleging the AI startup and its hardware chief orchestrated a coordinated campaign to steal confidential information about unreleased products. The complaint centers on Chang Liu, a former Apple employee who left for OpenAI and allegedly retained his company laptop for weeks after departure, downloaded proprietary files, and encouraged other Apple employees to share materials—drawings, components, and product details—with OpenAI.

The lawsuit names Tang Tan, OpenAI's chief hardware officer, as a key architect of the theft operation. Tan, who spent 24 years at Apple rising to vice president of product design, worked closely with industrial designer Jony Ive before both left to found IO Products, which OpenAI acquired in 2025. Apple alleges Tan systematically solicited trade secrets from Apple employees interviewing for roles at OpenAI, asking them to bring "actual parts" to sessions—a request that caught the attention of those involved, though some observers note that engineers discussing their work in interviews is standard practice.

The scale of the defection is the broader irritant: OpenAI has hired over 400 former Apple employees in recent years. Apple does not characterize this hiring as illegal, but the lawsuit frames it within a pattern of systematic misappropriation.

Security failures and brazen access

Ben Thompson, analyzing Apple's filing, notes that the company's security posture emerges as surprisingly weak. Liu kept his laptop after leaving and continued accessing Apple's internal servers for weeks due to what Apple claims was a bug. Apple failed to disable his credentials remotely or track that he had not returned the device—oversights that Thompson suggests should have been impossible at a company known for aggressive control over employee hardware.

Liu's behavior was neither subtle nor deniable: he downloaded dozens of proprietary hardware files and encouraged colleagues to do the same. Thompson describes Liu as "almost certainly guilty and an idiot to boot" for executing the theft on his company-issued machine, leaving a clear trail.

Why now, why thermonuclear

The lawsuit arrives as OpenAI readies an unspecified family of consumer devices and echoes Apple's 2010 declaration of "thermonuclear war" on Google over Android. But the timing and framing suggest this case is as much about Apple's deteriorating position in the AI era as it is about any single employee's misconduct.

The AI era has functionally upended Apple's playbook. Since 2022, the company has faced existential questions about competing in model development, fumbled its 2024 Siri redesign (prompting prominent observers to declare something "rotten in the state of Cupertino"), lost its supply chain primacy at TSMC, and absorbed a $10 billion revenue headwind from its own app-tracking transparency feature crushing Meta's ad targeting. Worse, losing 400 employees—many to Tan, the hardware lead of the iPhone, partnering with Jony Ive, Apple's most celebrated designer outside Steve Jobs—represents a symbolic rout.

Thompson's reading: Apple has a smoking gun in Liu's stupidity and is using it as a cudgel to exact revenge on the company now representing everything that has made Apple's life worse. The litigation may slow OpenAI's poaching, drain resources, and keep OpenAI in legal limbo before it even ships a product—a form of sand in the gears that works even if Apple never wins on the merits.

Historical precedent

Apple has litigated rivals before, though outcomes are mixed. In 2010, it sued Samsung and other Android manufacturers over smartphone design, securing a $539 million verdict in 2018 before settling on undisclosed terms. The Samsung battle ran seven years.

The more instructive precedent is Waymo v. Uber. Waymo accused Uber of acquiring autonomous driving trade secrets through Anthony Levandowski, a Google engineer who downloaded thousands of confidential files before founding Otto, which Uber acquired. Uber settled in February 2018, ceding 0.34% of its equity—worth $245 million at the time—and pledging not to use any of Waymo's confidential information. That promise arguably crippled Uber's autonomous vehicle program; the company eventually sold its self-driving unit to Aurora in 2020 for $4 billion and shifted to a platform-focused strategy.

A similar settlement here could force OpenAI to architect its devices around a self-imposed blindness to any information it may have acquired from Apple—a technical and legal mine field that could delay product launches or hobble competitive advantage even in victory.

The irony

Apple itself has been accused of stealing others' ideas frequently enough to spawn a verb: "Sherlocking," named after a Mac search utility that became the built-in Spotlight feature. The practice—where Apple absorbs a third-party innovation into iOS or macOS—has killed startups. Whether Apple's current lawsuit sits comfortably with that history is a separate question.

OpenAI has declined to comment beyond stating it has no interest in Apple's trade secrets and remains focused on building innovative technology. Liu and Tan did not respond to requests for comment.

The suit lands before OpenAI has shipped any consumer device and as the technology industry races to define what comes after the smartphone era. The winner could dominate consumer hardware for the next twenty years, just as the iPhone has. That's what makes this a thermonuclear escalation worth fighting—and worth fighting dirty.
