On July 11, 2026, Apple sued OpenAI in federal court in Northern California, accusing the company of stealing trade secrets “at every level,” from junior technical staff up to OpenAI’s own Chief Hardware Officer, Tang Tan. The complaint says Tan used Apple’s internal project code names while recruiting, asked job candidates to bring physical Apple hardware components to interviews, and coached departing engineers on how to dodge Apple’s security checks. One named engineer, Chang Liu, left Apple for OpenAI this year and kept his company laptop, which held confidential technical documents.

Here’s the argument: this lawsuit will not save Apple, because what OpenAI took was never sitting in a filing cabinet. Trade secrets law protects documents, drawings, source code: things you can point to and say “that’s ours.” But the real value Apple lost is the kind of knowledge that lives in a person’s head after eight years on a hardware team. Which tolerances actually work. Which vendors lie about yield. Which design choices got killed for reasons nobody wrote down. Chang Liu’s laptop is evidence. His judgment is not, and no subpoena gets that back.

You could argue this is just how Silicon Valley has always worked: engineers leave, they take what they know, competitors hire them for exactly that knowledge. True, most of the time. But asking candidates to bring physical components to interviews and coaching people on evading security procedures is not ordinary hiring. That is a company operationalizing theft as a recruiting strategy, which is why Apple is suing instead of just losing talent the normal way.

The partnership backstory makes this sharper. Apple and OpenAI struck a high-profile deal in 2024. Then OpenAI bought Jony Ive’s hardware startup, IO Products, for $6.4 billion and started building consumer devices of its own. Two years later they are opponents in federal court. That is not a coincidence. That is what happens when your former partner decides your talent pool is more valuable than your friendship.

Courts move slowly. OpenAI’s hardware ships regardless of how this case ends. Apple can win the lawsuit and still lose the market, because the thing it was actually trying to protect walked out the door already, wearing someone else’s badge.
