SAN FRANCISCO, United States (AFP) — Apple on Friday sued OpenAI, accusing the AI company of orchestrating a campaign to steal the iPhone maker’s trade secrets as it tries to develop its own consumer hardware device.

The lawsuit, filed in a federal court in California, paints a picture of an aggressive effort by OpenAI to poach Apple employees and extract confidential information to build its own device.

“At every level, from members of its Technical Staff to its Chief Hardware Officer, and in coordination with business partners, OpenAI has been stealing Apple’s trade secrets and confidential information,” Apple said in the 41-page complaint.

The suit will significantly complicate OpenAI’s plans for a hotly anticipated initial public offering.

The company, valued at roughly $852 billion, has raised more than $180 billion from investors, and expanding into consumer hardware was seen as a major opportunity for growth.

“We will always defend our teams’ hard work and innovations, and we are taking all appropriate steps to do so,” Apple said in a statement to AFP.

The suit names OpenAI, its hardware subsidiary io Products — the company co-founded by former Apple design chief Jony Ive — and two former Apple employees: Tang Yew Tan, now OpenAI’s chief hardware officer, and engineer Chang Liu.

Apple said it was seeking damages and an injunction barring OpenAI from using its confidential information, calling the lawsuit necessary after OpenAI failed to respond to concerns the company raised in February.

Tan spent 24 years at Apple, most recently as vice president of product design for the iPhone and Apple Watch, before co-founding io Products, which OpenAI acquired for roughly $6.5 billion in 2025.

Apple alleged that Tan used confidential project code names during OpenAI job interviews to probe candidates about unreleased Apple products.

He also allegedly told Apple employees to bring physical components, such as batteries, circuit boards, and other parts, to interviews for “show and tell” sessions.

Apple described its findings as “the tip of the iceberg,” saying it had limited visibility into what was happening behind OpenAI’s closed doors.

“OpenAI’s nascent hardware business now rests on the shakiest of foundations, rotten to its core by its illegal reliance on misappropriated trade secrets,” the complaint said.
