Apple’s Blockbuster Lawsuit Accuses OpenAI of Stealing Hardware Secrets to Build an iPhone Killer

 Apple’s Blockbuster Lawsuit Accuses OpenAI of Stealing Hardware Secrets to Build an iPhone Killer

## The partnership that brought ChatGPT to the iPhone has devolved into one of Silicon Valley's most dramatic trade-secret battles—with OpenAI's hardware ambitions and its IPO hanging in the balance.

---

### Introduction: From Partners to Legal Adversaries

In 2024, Apple and OpenAI stood side by side and announced a landmark partnership. OpenAI would provide the ChatGPT technology that would power Apple Intelligence and give Siri a much-needed brain transplant. It was a marriage of convenience between the world's most valuable company and the world's hottest AI startup.

Two years later, that partnership has shattered. On July 10, 2026, Apple filed a bombshell lawsuit in the U.S. District Court for the Northern District of California, accusing OpenAI of orchestrating a "coordinated pattern of misconduct at an institutional level" to steal its trade secrets.

"OpenAI's nascent hardware business now rests on the shakiest of foundations, rotten to its core by its illegal reliance on misappropriated trade secrets," Apple wrote in its complaint.

The lawsuit names OpenAI, its chief hardware officer Tang Tan, former Apple engineer Chang Liu, and io Products—the design startup founded by former Apple design chief Jony Ive that OpenAI acquired for $6.5 billion. The case threatens to disrupt OpenAI's long-anticipated hardware device, complicate its upcoming IPO, and escalate what was already one of Silicon Valley's most consequential rivalries.

### The Backstory: A Partnership That Unraveled

Apple first partnered with OpenAI in 2024 to integrate ChatGPT into its operating systems, seeking to catch up in the AI race. But the relationship soured as OpenAI began poaching Apple's top hardware talent.

According to the lawsuit, **more than 400 former Apple employees now work at OpenAI**. OpenAI has aggressively recruited current and former Apple leadership and engineering talent, primarily to build a dedicated hardware division. The tensions worsened when OpenAI announced plans to enter the hardware industry and acquired Jony Ive's startup, io Products, for $6.5 billion in 2025.

Apple also shifted its AI strategy away from OpenAI, turning to Google's Gemini to power Siri and Apple Intelligence. OpenAI grew disappointed with how Apple integrated ChatGPT and reportedly considered legal action against Apple. By July 2026, the partnership was effectively dead—and the legal battle had begun.

### The Allegations: A Systematic Campaign to Steal Apple's Hardware Secrets

Apple's 41-page complaint paints a picture of a deliberate, coordinated effort by OpenAI to acquire Apple's most sensitive hardware information.

#### Tang Tan: The Architect of the Theft

At the center of the lawsuit is **Tang Tan**, OpenAI's chief hardware officer and a former Apple vice president who spent 24 years at Apple leading product design for the iPhone, Apple Watch, AirPods, and other hardware.

Apple alleges that Tan:

- **Directed Apple employees interviewing at OpenAI to bring "actual parts" from Apple** to their interviews for "show and tell" sessions.

- **Coached departing Apple employees on how to avoid the "dreaded walk out"** that would immediately remove their access to Apple systems.

- **Instructed candidates still working at Apple** to bring proprietary hardware components to their interviews at OpenAI.

- **Used confidential Apple information** when recruiting candidates.

Tan left Apple in 2024 to co-found io Products alongside Jony Ive, and later joined OpenAI when it acquired io Products.

#### Chang Liu: The Engineer Who Took the Files

The lawsuit also names **Chang Liu**, a former electrical engineer who left Apple to join OpenAI in January 2026. According to Apple:

- **Liu failed to return a company-issued work laptop** after departing.

- He **exploited a software bug to access Apple's internal file servers** after leaving.

- He **accessed and downloaded "dozens of Apple's confidential hardware-related files"** including unreleased product details, engineering presentations, technical specifications, and proprietary project data.

- He also **accessed a former colleague's work computer** after leaving the company.

Apple said Liu did not respond to attempts to ensure he signed a confidentiality reminder, scheduled an exit interview, or confirmed he returned his company devices.

#### The Systemic Pattern

Beyond the individual allegations, Apple describes a systemic pattern of misconduct:

- **OpenAI coached Apple employees on how to handle their exits** to avoid scrutiny.

- **OpenAI approached Apple's manufacturing partners** to extract information about Apple's design and manufacturing processes.

- **OpenAI asked hardware firms to carry out a metal finishing technique** that Apple invented.

- **OpenAI encouraged employees to share confidential information, components, drawings, and other materials** related to upcoming products.

- **More than 400 former Apple employees are now at OpenAI**.

"At every level, from members of its technical staff to its chief hardware officer, and in coordination with business partners, OpenAI has been stealing Apple's trade secrets and confidential information," Apple wrote in its filing.

### What Apple Is Demanding

Apple is seeking sweeping relief:

- **Preliminary and permanent injunctions** preventing OpenAI from possessing, using, or disclosing Apple's confidential information.

- **An order requiring OpenAI to return all Apple intellectual property**.

- **Compensatory and exemplary damages**, though Apple has not specified an amount.

- **A requirement that OpenAI redesign its upcoming products** to ensure they don't include any Apple technology.

- **A jury trial**.

Apple also sent legal preservation orders to dozens of former Apple employees now working at OpenAI, demanding they preserve documents and data relevant to the case.

### OpenAI's Response: "We Have No Interest in Other Companies' Trade Secrets"

OpenAI has pushed back against the allegations. A spokesperson for the company said in a statement that OpenAI has "no interest in other companies' trade secrets" and remains "focused on building innovative technology that empowers people everywhere".

On July 14, 2026, OpenAI said it was "not aware of any evidence" that Apple's lawsuit has merit. The company is reviewing the complaint.

### The Stakes: OpenAI's Hardware Dreams and IPO Plans

The lawsuit couldn't come at a worse time for OpenAI. The company is preparing to release its first consumer hardware device—reportedly a new kind of AI gadget developed with Jony Ive—later this year. The lawsuit could throw a wrench into those plans, potentially forcing OpenAI to redesign its products if Apple proves its case.

OpenAI has also confidentially filed for an initial public offering, and the lawsuit threatens to complicate those plans. According to prediction market Kalshi, the probability that OpenAI completes its IPO by the end of 2026 fell from 22% to 18.5% after the lawsuit was filed. The odds of an IPO announcement by March 2027 dropped from 73% to 59%.

Even if the lawsuit ultimately fails, it could "bog down Sam Altman's company in injunctions and red tape" and disrupt OpenAI's device ambitions long before the case is resolved.

### The Broader Context: The Battle for Physical AI

The Apple-OpenAI lawsuit highlights a growing battle over physical, consumer-facing AI products. Apple, OpenAI, Meta, and others are racing to develop new gadgets that put artificial intelligence at the center, preparing for a post-smartphone future. Apple is working on devices including smart glasses, pendants, and camera-equipped AirPods.

The case also echoes the 2017 Waymo-Uber trade secrets lawsuit, where Waymo accused Uber of stealing its autonomous vehicle hardware designs. Uber ultimately agreed to pay $245 million to settle the case.
