Apple Sues OpenAI for Trade Secret Theft: Engineer's "Lol" Message 2026

Apple has filed a lawsuit against OpenAI, accusing the AI company of stealing trade secrets and breaching contract. The case centers on two former Apple employees, including a high-profile engineer whose message "Lol, I have access" has become the flashpoint of the scandal.

What Happened: Apple's 40-Page Complaint

In a 40-page complaint, Apple paints a damning picture of OpenAI's conduct. The lawsuit alleges that "at every level, from members of its technical staff to its head of hardware, and in coordination with business partners, OpenAI has been stealing trade secrets and confidential information from Apple."

The dispute threatens OpenAI's first hardware product, which is still in development. It also raises serious questions about Apple's internal security and the loyalty of its former employees.

The Two Former Apple Employees at the Center

Apple names two former employees: Chang Liu and Tang Tan. Both allegedly continued to access Apple's confidential information after joining OpenAI.

Chang Liu: The Engineer Who Kept His Laptop

Chang Liu, a senior electrical systems engineer, left Apple in January 2026 after eight years. According to the complaint, Liu retained his corporate laptop and discovered a flaw that allowed him to access Apple's internal servers.

He then downloaded a compilation of technical files exceeding 1,000 pages, covering unannounced technologies, features, and products, including technical specifications. The message "Lol, I have access" was reportedly sent by Liu, highlighting the brazen nature of the breach.

Tang Tan: A 24-Year Apple Veteran

Tang Tan spent 24 years at Apple, most recently as Vice President of Product Design for the iPhone and Apple Watch. His move to OpenAI was seen as a major coup for the AI company's hardware ambitions.

Apple alleges that Tan also misappropriated trade secrets. His deep knowledge of Apple's product design process makes him a key figure in the case.

Why This Matters: The Race for AI Hardware

OpenAI has been rumored to be working on a hardware device, possibly an AI-powered gadget. Apple's lawsuit could derail those plans if it leads to an injunction or damages.

The case also underscores the fierce competition for talent and intellectual property in the tech industry. Companies are increasingly willing to litigate to protect their secrets.

What to Watch Next

OpenAI has not yet responded publicly to the lawsuit. The case will likely hinge on digital forensics and whether OpenAI can prove it did not use any of Apple's confidential information.

Earlier coverage in Wrongful Arrest Lawsuit Filed in Savannah Guthrie Mother Case shows how the argument developed.

For Apple, the lawsuit is a wake-up call about data loss prevention. The fact that a former employee could access internal servers months after leaving suggests serious security gaps.

For OpenAI, the stakes are high. A loss could result in significant damages and an injunction against its hardware plans. The company's reputation is also on the line.
