Apple Escalates Trade Secrets Lawsuit Against OpenAI Over Hardware Secrets and Ex-Employees

In brief: Apple has filed for a preliminary injunction in its ongoing trade secrets lawsuit against OpenAI, claiming that more than a dozen former employees downloaded confidential documents regarding unannounced hardware. OpenAI responded with a public blog post publishing email receipts, asserting it neither holds nor desires Apple's proprietary technology.

The Legal Battle Over Next-Generation AI Hardware

Tensions between Apple and OpenAI have reached a boiling point. The Cupertino tech giant has escalated its legal offensive by filing a motion for a preliminary injunction in federal court. Apple's primary objective is to halt OpenAI's development of standalone consumer AI hardware—projects closely linked to OpenAI's acquisition of io, the hardware startup co-founded by former Apple design chief Sir Jony Ive.

As reported by TechCrunch, Apple's latest filing asserts that its ongoing forensic investigation has identified at least 11 additional former employees who may have accessed or exfiltrated trade secrets. These individuals add to the key figures named in the original lawsuit, including OpenAI Chief Hardware Officer Tang Yew Tan and senior engineer Chang Liu, both accused of retaining proprietary schematics and screenshots of unannounced Apple products before leaving the company.

Allegations of Data Exfiltration and Systemic Offboarding Flaws

At the core of Apple's complaint is the alleged theft of confidential product blueprints, hardware component specs, and supply chain details. Court documents claim that engineer Chang Liu maintained access to Apple's cloud storage weeks after resigning in January by exploiting authentication loopholes, allegedly downloading technical files and advising another colleague on how to extract documentation ahead of her OpenAI interview.

According to details shared by Ars Technica, Apple is pushing for expedited discovery to compel OpenAI executives and key engineers to sit for depositions under oath. The lawsuit reflects growing friction as more than 400 former Apple engineers have joined OpenAI over recent years, raising alarm bells inside Cupertino regarding institutional knowledge transfer.

OpenAI Rebuts in the Court of Public Opinion

OpenAI quickly pushed back against Apple's motion, taking the dispute directly to the public. As highlighted by The Verge, the ChatGPT creator published a blog post titled "Apple is getting this wrong," attaching iMessage screenshots and legal email threads to challenge Apple's narrative.

OpenAI characterized the lawsuit as "careless, aggressive, and oddly personal," declaring that it neither possesses nor wants any of Apple's trade secrets. OpenAI argued that Apple engineers themselves had reached out to Liu post-departure asking for assistance locating specific files—a scenario Apple now frames as unauthorized access. Furthermore, OpenAI revealed that Apple's outside counsel initially sent warning notices to the wrong individual due to confusing two Asian surnames, exposing procedural oversights in Apple's initial inquiry.

Mocchi's take

The trade secret battle between Apple and OpenAI marks a pivotal shift in the AI race from software algorithms to proprietary hardware ecosystems. For enterprise tech leaders and software builders, this dispute underscores two vital lessons: first, the absolute necessity of rigorous offboarding protocols and zero-trust cloud permission management, as systemic administrative oversights can leave organizations vulnerable to severe legal exposure; second, the reality that next-generation AI agents will increasingly depend on specialized consumer hardware. As tech giants clash over physical device intellectual property, enterprises must ensure their AI strategies remain platform-agnostic to safeguard against ecosystem lock-in and regulatory litigation.
