Apple filed a federal lawsuit against OpenAI, accusing the AI company of orchestrating trade secret theft through former Apple employees now working on OpenAI's hardware ambitions. The complaint alleges Chief Hardware Officer Tang Tan and engineer Chang Liu misappropriated confidential Apple technologies, unreleased hardware designs, and proprietary project data to advance OpenAI's nascent consumer device business.

Apple Sues OpenAI Over Alleged Pattern of Trade Secret Theft

Apple filed a lawsuit Friday against OpenAI in the U.S. District Court for the Northern District of California, alleging trade secret theft and breach of contract orchestrated by the AI company's senior leadership

1

. The iPhone maker claims it uncovered a systematic pattern of former Apple employees stealing hardware secrets and misappropriated confidential Apple technologies to benefit OpenAI's hardware ambitions

2

. Named as defendants are OpenAI Chief Hardware Officer Tang Tan, technical staff member Chang Liu, and IO Products—the startup founded by legendary designer Jony Ive that OpenAI acquired for $6.5 billion in 2025

The lawsuit against OpenAI marks what could become the highest-stakes intellectual property battle in Silicon Valley since Waymo sued Uber in 2017 over autonomous vehicle technology, a case that settled for $245 million

2

. Apple alleges that OpenAI has hired more than 400 former Apple employees, creating what the company describes as an environment where "such misconduct is normalized and exemplified by leadership"

Stealing Hardware Secrets Through Systematic Recruitment Tactics

According to the complaint, Tang Tan—who spent 24 years at Apple as VP of product design for the iPhone and Apple Watch—allegedly used Apple's confidential project code names during OpenAI's recruiting process and asked job candidates to bring actual Apple hardware components to their interviews

1

. Apple claims Tan directed prospective hires "still working for Apple to bring 'actual parts' from Apple to their interviews for 'show and tell' sessions," specifically naming batteries, logic boards, and shields as sought-after components

2

.

The filing alleges Tan coached departing Apple employees on how to evade security procedures, asking for details about unannounced products and emailing himself information about Apple's suppliers before leaving the company

3

. Apple identified one instance where a then-Apple employee was "screenshotting and downloading files relating to a highly confidential Apple project" in the hours before an interview with Tan at OpenAI

Chang Liu Accused of Downloading Confidential Documents

Chang Liu, who worked at Apple for eight years as a senior systems electrical engineer before joining OpenAI in January 2026, allegedly failed to return his Apple-issued laptop and used it to access confidential documents

1

. According to the lawsuit, Liu "surreptitiously accessed and downloaded dozens of Apple's confidential hardware-related files," including unreleased hardware designs, engineering presentations, technical specifications, and proprietary project data about unannounced technologies, features, and products

3

.

Apple's investigation revealed that Liu wrote to a former colleague about still having access to Apple's internal file-sharing system—access enabled by a bug that has since been fixed

2

. The complaint further alleges Liu coached an Apple employee he was recruiting to join OpenAI on how to "'avoid trouble with the security team' when copying confidential Apple files"

OpenAI's Hardware Ambitions Fuel Competitive Tensions

The accusations arrive as OpenAI pursues AI-powered consumer device development that could directly compete with Apple's core business. Industry analyst Ming-Chi Kuo suggested in April that OpenAI might be developing a smartphone relying on AI agents instead of apps—representing one of the largest threats to the iPhone to date

1

. Apple's filing references a proprietary metal finishing technique allegedly used by OpenAI after the company misled a partner into believing it had Apple's permission

1

.

The lawsuit states that "OpenAI's nascent hardware business now rests on the shakiest of foundations, rotten to its core by its illegal reliance on misappropriated trade secrets"

1

. Apple and OpenAI have been partners since 2024, when they announced a landmark deal to distribute ChatGPT on iPhones, MacBooks, and iPads for integration with Siri

2

. However, the relationship has reportedly frayed in recent years, prompting Apple to rely more on Google's Gemini AI technology

Apple Seeks Injunctions and Evidence Preservation

Apple sent a letter to OpenAI in February raising concerns about the alleged misconduct but received no response, according to the complaint

1

. The company is now requesting a jury trial and asking the court to bar OpenAI from using or disclosing its trade secrets, require the company to return any confidential Apple materials, and preserve evidence related to the case

5

. Apple is also seeking damages, attorney fees, and other injunctions

5

.

In a prepared statement, Apple spokesperson Hannah Smith emphasized: "At Apple, our teams are constantly developing breakthrough technologies to create the best products and services in the world, and protecting their work and intellectual property is something we take very seriously"

4

. The filing acknowledges that "this is the tip of the iceberg" and that "Apple lacks visibility into what's been happening behind closed doors at OpenAI"

1

. If the case proceeds to trial, it could drag several former high-level Apple employees into testimony through legal discovery, potentially revealing the full scope of OpenAI's AI hardware plans and how extensively unreleased Apple technologies may have influenced them
