OpenAI coached workers on how to preserve access to secrets before they left
When former allies become rivals, the question of what knowledge belongs to whom grows urgent. Apple's lawsuit against OpenAI, filed in federal court in California, alleges that the AI company systematically harvested confidential product information by recruiting roughly 400 Apple employees and coaching them to carry proprietary secrets across the threshold. At the center of the dispute stands Tang Tan, once Apple's VP of product design and now OpenAI's hardware chief — a figure whose career arc traces the very fault line between collaboration and competition. The case arrives at a charged moment, as OpenAI moves toward a public offering and enlists Apple's legendary former designer Jony Ive, suggesting that what began as partnership has quietly become a contest for the future of intelligent devices.
- Apple alleges OpenAI ran a coordinated, multi-level operation to extract trade secrets — not a rogue act, but a strategy reaching from technical staff to executive leadership.
- Former Apple VP Tang Tan is accused of using job interviews as intelligence-gathering sessions, prompting candidates to reveal specifications and designs for unreleased products.
- Hardware engineer Chang Liu allegedly accessed dozens of internal Apple documents without authorization before departing, then used that information to build hardware for OpenAI.
- OpenAI's recruitment of approximately 400 Apple employees in the lead-up to its IPO frames the alleged theft as part of a deliberate competitive acceleration.
- Apple is demanding destruction of all obtained materials and a redesign of any products built on copied technology, raising the stakes well beyond financial damages.
- OpenAI denied any interest in rivals' secrets but declined to address the specific accusations, leaving the most damaging claims unanswered as tensions between the two companies harden.
Apple filed a federal lawsuit in California on July 11 against OpenAI, accusing the company of orchestrating a systematic campaign to steal confidential information about unreleased products. At the center of the complaint is Tang Tan, OpenAI's chief hardware officer and a former Apple vice president who oversaw development of the iPhone, Apple Watch, and AirPods. Apple alleges that Tan used the interview process to encourage Apple employees to share proprietary details — specifications, component designs, technical drawings — before joining OpenAI.
The lawsuit also names Chang Liu, a former Apple hardware engineer who allegedly accessed dozens of internal documents without authorization and used that information to develop hardware at OpenAI. Beyond individual actors, Apple contends that OpenAI actively coached departing employees on how to preserve access to confidential files during their transitions — a claim that frames the alleged misconduct as institutional rather than incidental. The scale is striking: OpenAI is said to have hired approximately 400 Apple employees in the months approaching its planned IPO.
The lawsuit marks a sharp turn in what had been a productive relationship. OpenAI's technology underpins Apple Intelligence and powers enhancements to Siri, but that partnership has visibly frayed. The breaking point came when OpenAI recruited Jony Ive — the designer who defined Apple's aesthetic identity for decades — to help build new devices, signaling a move from collaboration into direct competition.
OpenAI responded by denying any interest in competitors' trade secrets, though it did not address the specific allegations against Tan or Liu. Apple is seeking the destruction of all misappropriated materials and a redesign of any products built on stolen technology — demands that, if granted, could reshape OpenAI's hardware ambitions at a pivotal moment in the company's history.
Apple filed suit against OpenAI in federal court in California on July 11, alleging that the artificial intelligence company orchestrated a systematic campaign to extract confidential information about unreleased products from Apple's workforce. The lawsuit names Tang Tan, OpenAI's chief hardware officer, as a central figure in the scheme. Tan previously held the position of vice president of product design at Apple, where he oversaw development of the iPhone, Apple Watch, AirPods, and other hardware products across the company's engineering division.
According to the complaint, Tan used job interviews at OpenAI as an opportunity to encourage Apple employees to share details about upcoming products—specifications, component designs, technical drawings, and other proprietary materials. The suit also identifies Chang Liu, a former Apple hardware engineer, as having provided OpenAI with confidential files by illegally accessing dozens of Apple's internal documents related to unreleased products and engineering presentations. Liu subsequently developed hardware for OpenAI using information obtained through this unauthorized access.
Apple's legal filing contends that OpenAI went further than simply accepting information from departing employees. The company allegedly "actively coached" workers on how to manage their transitions in ways that would preserve their ability to access and extract secret files. The scale of the alleged recruitment effort is substantial: according to the lawsuit, OpenAI has successfully hired approximately 400 Apple employees in the months leading up to its planned initial public offering.
The relationship between the two companies had been collaborative until recently. OpenAI provided critical technology that powers Apple Intelligence, the company's new artificial intelligence features, as well as enhancements to Siri, Apple's digital assistant. But that partnership has fractured. Tensions escalated when OpenAI recruited Jony Ive, the legendary Apple designer who shaped the aesthetic and philosophy of the company's most iconic products, to help develop new devices. The move signaled a fundamental shift from cooperation to direct competition.
In its response, OpenAI dismissed the allegations, stating that the company has "no interest in other companies' trade secrets" and remains committed to developing innovative technology. The company did not address the specific claims about Tan's recruitment practices or Liu's file access.
Apple is demanding that OpenAI destroy all proprietary materials it obtained and redesign any upcoming products that incorporate copied technology. The lawsuit characterizes the alleged theft as systematic and coordinated across multiple levels of OpenAI's organization, from technical staff to executive leadership, and involving coordination with business partners. The case represents an escalation of competitive tensions between two technology giants at a critical moment—as OpenAI prepares for public markets and Apple seeks to protect the competitive advantages embedded in its unreleased hardware roadmap.

The Hearth Conversation Another angle on the story
Why would someone like Tang Tan, who built Apple's most successful products, turn around and help OpenAI extract Apple's secrets?
He wasn't just accepting information—he was actively soliciting it during interviews. That suggests a deliberate strategy, not casual conversation. When you've spent years at the top of a company's design hierarchy, you understand exactly what information is valuable and how to extract it.
But 400 employees? That's not espionage, that's just hiring.
The lawsuit says OpenAI coached them on how to preserve access to files before they left. That's the distinction. Hiring is normal. Teaching people how to extract and secure proprietary data on their way out is something else entirely.
They were collaborators just months ago. What broke?
Jony Ive. When OpenAI brought in the person who designed the iPhone, it signaled they weren't interested in partnership anymore—they wanted to compete directly. That's when the gloves came off.
Does Apple have a real case here?
They have names, dates, and specific allegations about unauthorized file access. Whether a court agrees that it constitutes theft depends on what Liu actually took and whether OpenAI knowingly benefited from it. The coaching angle is harder to prove—that requires showing intent.
What happens to OpenAI's IPO if they lose?
Massive liability, destroyed reputation with enterprise clients, and the kind of discovery process that could expose how the company actually operates. That's probably why they're denying everything rather than settling quietly.
