Apple v. OpenAI: What the Trade-Secret Lawsuit Actually Alleges

On July 10, 2026, Apple filed suit against OpenAI — plus two of its own former employees — in the U.S. District Court for the Northern District of California. The claims: trade secret misappropriation and breach of contract, tied to OpenAI's push into consumer hardware. This isn't a vague IP shakedown; the complaint names names and describes specific conduct.

The two people at the center of it

• Tang Tan — OpenAI's Chief Hardware Officer and a 24-year Apple VP before he left. Apple alleges he used internal Apple project code names while recruiting, asked candidates to bring Apple hardware to interviews, and coached departing Apple staff on how to evade the company's exit-security process.
• Chang Liu — an eight-year Apple senior systems engineer who joined OpenAI in 2026. Apple alleges he failed to return a company laptop, downloaded confidential technical documents on his way out, and shared Apple's confidential information with other Apple employees who were interviewing at OpenAI.

Apple says it sent OpenAI a warning letter in February 2026 and got no response before filing. OpenAI's public statement so far is terse: "We have no interest in other companies' trade secrets."

Why now: OpenAI is building a device

The timing isn't a coincidence. OpenAI bought Jony Ive's design studio io in 2025 for $6.5 billion and has been reported to be working on a consumer AI hardware product — something positioned to compete with, not plug into, the iPhone. Hiring Apple's own former hardware chief to lead that effort was always going to draw scrutiny; Apple's complaint argues it crossed from aggressive recruiting into deliberate extraction of confidential manufacturing methods, supplier relationships, and device designs.

The builder angle: talent wars have legal edges

For anyone running an engineering org in a hot AI category, this case is a useful data point, not just gossip. Hiring senior talent from a competitor is normal and legal. What Apple is alleging is different in kind: using code names from a former employer during recruiting, prompting new hires to bring proprietary hardware to interviews, and instructing people on how to route around a former employer's offboarding controls. Those are the specific acts that turn a hiring spree into a trade-secret exposure — and they're exactly the kind of thing a fast-scaling team can drift into without meaning to, especially when recruiting pressure is high and the line between "domain knowledge" and "someone else's confidential IP" gets blurry in a candidate's head, not just a lawyer's.

What happens next

Apple is asking the court to bar OpenAI from using or disclosing the disputed material, order the return of Apple property, and preserve evidence — the standard first moves in a trade-secret case, ahead of any damages fight. OpenAI has yet to file a formal response. Given the stakes — a first-party AI hardware push versus the company that defined the category — expect this to run for a while, and expect it to shape how the next wave of AI hardware teams handle recruiting from Apple's supply chain and hardware org specifically.
