Apple just filed a federal lawsuit against OpenAI, alleging the AI company orchestrated the theft of trade secrets related to consumer hardware development. The suit, filed in the Northern District of California, also names two former Apple employees as defendants.

What Apple is alleging

The 41-page complaint lays out a detailed case. Apple accuses OpenAI and the two former engineers of conspiring to steal confidential designs, supplier lists, and engineering files related to consumer device development.

The allegations go beyond simple poaching. Apple claims OpenAI actively coached departing engineers on how to circumvent the company’s internal security protocols.

Among the more striking details in the complaint, Apple points to what it describes as casual revelations by employees about accessing restricted network storage.

The suit was filed on July 10, 2026, and represents one of the most aggressive intellectual property actions in the AI industry this year.

From partners to adversaries

Apple and OpenAI had built a commercial relationship around integrating generative AI features into Apple’s products. ChatGPT became part of the Apple ecosystem, a move that signaled cooperation between two of the most influential entities in tech.

OpenAI has been making increasingly loud noises about entering the consumer hardware market, exploring physical devices that would bring AI directly into users’ hands. Apple’s lawsuit appears timed to disrupt that trajectory.
