In a staggering legal escalation that has sent shockwaves through Silicon Valley, Apple has filed a federal lawsuit against OpenAI, accusing the artificial intelligence giant of orchestrating a "widespread, institutional scheme" to steal its most sensitive hardware trade secrets. The blockbuster complaint, filed on Friday, July 10, 2026, in the Northern District of California, alleges that OpenAI’s entire new consumer hardware division is built on a "foundation of theft" orchestrated by poaching key Apple engineers and smuggling unreleased prototypes.

The lawsuit paints a dramatic picture of espionage, accusing OpenAI of coaching job candidates to physically sneak components out of Apple’s offices in "show and tell" sessions, exploiting a network security glitch to download thousands of confidential engineering files, and tricking Apple’s exclusive manufacturing partners into sharing proprietary processes. The legal action comes as a stunning blow to the 2024 partnership between the two companies, which centered on integrating ChatGPT into Apple devices.

According to court documents, the core of Apple's grievance lies in OpenAI's alleged desperation to deliver its first commercial hardware product. The complaint asserts that rather than investing the necessary billions of dollars and years of research required to build a hardware business from the ground up, OpenAI took "unlawful shortcuts."

The Methods of Theft: From Bugs to Backpacks

Apple’s legal team detailed several distinct methods by which OpenAI allegedly obtained its secrets. The most technically brazen involves former Apple systems engineer Chang Liu. The lawsuit claims Liu kept his Apple-issued work laptop after quitting and discovered an unpatched authentication bug that allowed him to remain logged into Apple’s secure internal servers. While working at OpenAI, Liu allegedly exploited this bug to download dozens of top-secret engineering files, blueprints, and custom manufacturing presentations.

• The “Show and Tell” Interviews: OpenAI’s Chief Hardware Officer, Tang Tan (a 24-year Apple veteran who previously led iPhone design), is accused of coaching job candidates to bypass Apple security and physically smuggle unreleased hardware parts to OpenAI headquarters for engineering analysis.
• Digital Hoarding: Multiple departing employees allegedly emailed confidential supplier lists and proprietary project data to personal accounts before leaving Apple.
• Supply Chain Deception: OpenAI is accused of approaching one of Apple’s exclusive metal-finishing partners and misleading them into believing Apple had authorized the use of a secret, proprietary metal-shaping process.

OpenAI's Hardware Ambitions and Fallout

OpenAI has been secretly developing a "family" of screenless AI-powered consumer devices, including a tabletop smart "puck" and a vision-equipped home speaker. The company had ambitious plans to manufacture 100 million units, but the lawsuit is already throwing those plans into disarray. The lawsuit notes that OpenAI has already delayed its product launch timeline to at least April 2027.

In response to the lawsuit, OpenAI spokesperson Drew Pusateri issued a brief statement: "We have no interest in other companies' trade secrets. We remain focused on building innovative technology that empowers people everywhere." However, the company has already been forced to abandon the "io" brand name for its hardware, which it had acquired through the purchase of Jony Ive's startup.

Apple is seeking a federal injunction to block OpenAI from using any of its trade secrets, a complete return of all stolen data, and an order forcing the company to redesign any upcoming hardware that utilizes its technology. The legal filing marks a dramatic souring of relations between the two tech titans, who had previously enjoyed a close partnership.
