 Apple Sues OpenAI, Alleging Theft of Trade Secrets to Build AI Hardware

**The lawsuit claims a "coordinated pattern of misconduct" involving over 400 former Apple employees, including key hardware executives, who allegedly brought confidential information to OpenAI to launch its own consumer devices.**

## Introduction: The Partnership That Turned Sour

In a dramatic escalation of Silicon Valley tensions, Apple has filed a federal lawsuit against OpenAI, accusing the artificial intelligence company of systematically stealing trade secrets to develop its own consumer hardware.

The lawsuit, filed on July 10, 2026, in the U.S. District Court for the Northern District of California, alleges that OpenAI orchestrated a "coordinated pattern of misconduct at an institutional level" to poach Apple employees and extract confidential information about unreleased products, manufacturing processes, and supplier relationships.

"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 represents a stunning rupture between two companies that were once close partners. Just two years ago, Apple integrated ChatGPT into its devices as it sought to catch up in the AI race. Now, they are locked in a legal battle that could reshape the future of AI hardware.

## The Allegations: A "Pattern of Theft"

### Poaching and Extraction

Apple's 41-page complaint paints a picture of a systematic campaign by OpenAI to acquire Apple's intellectual property. The company alleges that OpenAI:

- **Actively recruited Apple employees** and encouraged them to bring confidential information

- **Coached departing employees** on how to avoid security protocols and the "dreaded walk out" that would immediately remove their access

- **Instructed job candidates** still working at Apple to bring "actual parts" as "props" for "show and tell" sessions during interviews

- **Acquired information from Apple suppliers** and used proprietary manufacturing techniques

"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," the lawsuit states.

### The Scale of the Operation

According to the lawsuit, **more than 400 former Apple employees now work at OpenAI**. Apple alleges that this mass exodus was not coincidental but part of a deliberate strategy to build a hardware division on the foundation of Apple's expertise.

The company claims it first raised concerns with OpenAI in February 2026 but was "ultimately ignored".

## The Key Figures

### Tang Yew Tan: From Apple VP to OpenAI's Hardware Chief

The lawsuit names **Tang Yew Tan** (also referred to as Tang Tan), OpenAI's chief hardware officer, as a central figure in the alleged misconduct.

Tan spent **24 years at Apple**, rising to vice president of product design for iPhone, Apple Watch, AirPods, and other hardware offerings. He left the company in 2024 to co-found io Products, an AI devices startup alongside former Apple design chief Jony Ive. OpenAI acquired io Products last year for **$6.5 billion**.

Apple alleges that Tan:

- **Methodically used Apple's confidential information** to benefit OpenAI

- **Took information about Apple suppliers** with him to OpenAI

- **Directed job candidates** still working at Apple to bring Apple parts to their interviews

- **Discussed company meetings with a supplier** and emailed himself information about Apple's supply chain

### Chang Liu: The Engineer Who Took Files

The lawsuit also names **Chang Liu**, a senior electrical engineer who worked at Apple for eight years.

According to the complaint, Liu:

- **Joined OpenAI in January 2026**

- **Failed to return an Apple-issued laptop** after departing

- **Exploited a network bug** to access Apple's internal systems

- **Downloaded "dozens of Apple's confidential hardware-related files"** including unreleased product details, engineering presentations, and technical specifications

### io Products and Jony Ive

The lawsuit also names **io Products**, the design startup founded by Jony Ive, Apple's former design chief. OpenAI acquired the company last year.

Notably, **Ive himself is not named as a defendant** and the suit does not accuse him of wrongdoing.

## Apple's Demands

Apple is seeking multiple forms of relief:

- **A court order** prohibiting OpenAI from possessing, using, or sharing Apple's trade secrets

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

- **Unspecified monetary damages**

- **A jury trial**

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

## OpenAI's Response

OpenAI has denied the allegations.

**Drew Pusateri**, a spokesperson for OpenAI, told multiple news outlets: "We have no interest in other companies' trade secrets. We remain focused on building innovative technology that empowers people everywhere".

The company said it is "reviewing the complaint".

## The Context: From Partners to Rivals

### A Partnership That Unraveled

The lawsuit marks a dramatic reversal in the relationship between the two tech giants.

In **2024**, Apple and OpenAI announced a partnership to integrate ChatGPT into Apple's operating systems for iPhones, iPads, and Macs. Apple sought OpenAI's help as it was "behind in the AI race sparked by ChatGPT's arrival".

But tensions began to simmer when OpenAI acquired io Products, signaling its ambition to enter the hardware market. More recently, Apple shifted more of its AI features to run on **Google's Gemini** model.

### The Hardware Race

Both companies are racing to develop next-generation AI devices. Apple is reportedly working on smart glasses, pendants, and camera-equipped AirPods. OpenAI is expected to release its first hardware product—reportedly a type of keyboard for use with its AI tools—as early as this month.

The lawsuit could throw a wrench into those plans. Legal experts suggest the case could "significantly delay OpenAI's hardware development process".

## What This Means for the Industry

### A New Frontier in Trade Secret Litigation

Legal experts note that this case is unusual because it involves **hardware trade secrets**, whereas most AI trade secret litigation focuses on software. This could complicate the legal proceedings.

### Implications for OpenAI's IPO

OpenAI is reportedly planning to go public soon in a highly anticipated IPO. The lawsuit could complicate those plans.

### A Warning to Tech Companies

The case serves as a warning to technology companies about the risks of aggressively poaching talent from competitors. California law allows employees to switch jobs, but if OpenAI is found to have knowingly used stolen trade secrets, it could face severe consequences.

## Conclusion: A Legal Battle That Could Reshape AI Hardware

Apple's lawsuit against OpenAI is more than just a legal dispute. It's a battle for the future of AI hardware—a market that both companies see as the next frontier.

The allegations are serious: a coordinated campaign to poach employees, extract trade secrets, and build a hardware business on the foundation of Apple's intellectual property. If proven, the case could force OpenAI to redesign its upcoming products and significantly delay its hardware ambitions.

For OpenAI, the stakes are high. A protracted legal battle could complicate its planned IPO and cast a shadow over its hardware division. For Apple, the lawsuit is a defense of its most valuable asset: the intellectual property that has made it one of the world's most valuable companies.

As the case moves forward, it will likely hinge on whether Apple can prove that OpenAI knowingly used stolen trade secrets—and whether the "more than 400" former Apple employees at OpenAI were part of a coordinated scheme or simply talented professionals exercising their right to change jobs.

One thing is certain: the relationship between these two tech giants has been permanently altered. The partnership that once brought ChatGPT to the iPhone has given way to a legal battle that could define the next era of the AI hardware race.
