Apple is sending legal letters to dozens of OpenAI employees, escalating its trade-secrets lawsuit into a campaign that could chill talent mobility across the tech industry

Apple's Trade-Secrets Lawsuit Has Become a Campaign Against Individual Engineers

Apple is sending legal letters to dozens of OpenAI employees who used to work at Apple, turning its July 10 trade-secrets lawsuit into a direct pressure campaign against individual engineers across OpenAI's hardware division 1.

A company suing a competitor over stolen intellectual property is corporate routine. A company sending legal letters to dozens of individual engineers at that competitor is a different kind of move. It makes the decision to change jobs carry personal legal risk.

The lawsuit itself, a 41-page complaint filed July 10, alleges that OpenAI orchestrated a coordinated effort to extract confidential information from Apple employees. Apple names OpenAI chief hardware officer Tang Yew Tan as the director of that effort. Tan spent 24 years at Apple, most recently as VP of product design for iPhone and Apple Watch 2.

The allegations are granular. Apple claims Chang Liu, a former senior systems electrical engineer, exploited an authentication bug to access Apple's confidential systems after leaving the company, using a colleague's Apple-issued work computer. That colleague, Yu-Ting "Alyssa" Peng, allegedly served as a conduit between the two companies before joining OpenAI herself. Peng is not a defendant 2.

Apple also alleges that Tan instructed job candidates still employed at Apple to bring physical parts, prototypes, and design files to their OpenAI interviews. The complaint further claims OpenAI coached departing employees on evading Apple's security procedures to retain access to confidential systems longer 2.

Apple says it first contacted OpenAI about these concerns in February and received no response before filing suit 2.

OpenAI responded on July 14, calling the complaint meritless and arguing for the freedom to work wherever you choose 1. Its initial statement on July 13 was more measured: "We have no interest in other companies' trade secrets" 2.

The legal letters shift the dispute from one company to many individuals. Apple's complaint states that more than 400 former Apple employees now work at OpenAI 2. Apple is now sending letters to dozens of them. If that tactic works, companies with substantial legal budgets gain a retention mechanism that operates outside any employment contract: the implicit threat that leaving means hiring your own lawyer.

This fight centers on OpenAI's push into hardware. The company acquired io, founded by former Apple employees including Jony Ive, for $6.5 billion, and is rumored to be developing a device that could compete with the iPhone 2. Apple's complaint describes OpenAI's hardware business as "rotten to its core" by its reliance on misappropriated trade secrets 2. The complaint also suggests the documented allegations are a fraction of what Apple expects to uncover through discovery 2.

Apple frames this as theft. OpenAI frames it as an attack on the right to switch employers. Both characterizations can hold simultaneously. An engineer who exploits an authentication bug to download files after resigning is doing something that resembles theft. A legal campaign that reaches dozens of engineers for the act of working at a competitor creates pressure regardless of what each individual did.

The complaint details specific allegations against named individuals. The legal letters reach well beyond them. Any engineer who handles proprietary technology now has a new variable to weigh alongside salary and equity: taking a job at a rival could mean a letter from a former employer's legal department.

In a sector where the talent supply is finite and movement between companies is constant, that variable changes career calculations. Whether targeting individuals becomes a standard corporate practice or stays a one-company escalation depends on what happens next. Apple has the resources to sustain this fight indefinitely. The engineers on the receiving end do not.
