Apple sued OpenAI on July 10 in the Northern District of California, and the complaint reads less like a personnel grievance than an attempt to strand a $6.5 billion acquisition on the runway. The named defendants include io Products, the design startup OpenAI bought for that sum, along with OpenAI’s hardware chief Tang Tan, a former Apple VP who ran product design for the iPhone and Apple Watch, and engineer Chang Liu.

The allegations are unusually cinematic. Per TechCrunch, Tan used Apple’s internal project codenames on recruiting calls, coached departing Apple staff on evading security procedures, and asked candidates to bring hardware components to interviews. Axios reports that batteries, logic boards, and SiPs were requested by category, for what Tan reportedly called “show and tell.” Liu, according to the same filing, walked out of Apple in 2026 with a company laptop he never returned and used it to pull confidential technical documents. Apple’s filing calls the theft an operation running “at every level, from members of its Technical Staff to its Chief Hardware Officer,” and describes the current complaint as “the tip of the iceberg.”

OpenAI’s public response, to Axios: “We have no interest in other companies’ trade secrets.”

The remedy is where this gets structural. Bloomberg reports Apple is seeking preliminary and permanent injunctions barring OpenAI and io from possessing or using the alleged trade secrets. An injunction of that shape doesn’t just extract damages, it forecloses the roadmap. Chris Lehane, OpenAI’s chief global affairs officer, told Axios at Davos in January that the first io device would ship in the first half of 2026. It hasn’t. The New York Times now reports OpenAI’s IPO listing is slipping to 2027.

Read alongside the fact that Apple’s fall Siri revamp reportedly runs on Google Gemini rather than any OpenAI model, this looks less like an isolated dispute than the visible endpoint of a relationship that quietly ended months ago. Litigation is the divorce filing, not the fight. What Apple is asking a federal judge to do is convert its ex-partner’s most expensive bet into a stranded asset.
