On a Friday morning in a federal courthouse in California, Apple filed what may prove to be one of the most consequential intellectual-property lawsuits in the history of consumer technology. The complaint, running to 41 pages, names two former Apple employees — a senior systems electrical engineer and a former vice president of product design for the iPhone and Apple Watch — alongside three OpenAI entities: OpenAI Foundation, OpenAI Group PBC, and io Products. Apple's central allegation is blunt: its former staff stole confidential hardware secrets and delivered them to a rival. The details alleged in the filing are specific and damaging.

One defendant, Apple claims, exploited an authentication vulnerability in the company's internal network after leaving — using an unreturned work laptop to download dozens of confidential hardware-related files. The other is accused of emailing himself sensitive supplier information and internal industry summaries in the weeks before his departure. Apple argues that the misconduct extended well beyond junior staff, reaching, in its own words, "from members of its Technical Staff to its Chief Hardware Officer." The lawsuit represents a sharp rupture in what had been, until recently, a carefully managed partnership.

Apple had integrated ChatGPT access into Siri and allowed iPhone users to subscribe to ChatGPT directly from iOS settings. That cooperative arrangement now sits awkwardly alongside OpenAI's broader ambitions in consumer hardware — ambitions sharpened last year when OpenAI acquired io Products, a startup co-founded by the celebrated former Apple designer Jony Ive. What OpenAI is actually building remains deliberately vague; the company has described it only as "a new way of interacting with AI" that moves beyond conventional devices.
