Apple sues OpenAI, and the AI hardware fight goes to court

The two most important companies in consumer technology are now in court. On 10 July, Apple filed a lawsuit against OpenAI in the Northern District of California, alleging that the AI company systematically poached Apple employees and used Apple trade secrets to build its hardware division. On 3 August, Apple moved for a preliminary injunction, asking the court to bar OpenAI and two former Apple executives, including Tang Tan, who led iPhone hardware design for years, from accessing or using Apple’s confidential information while the case proceeds. OpenAI has denied the allegations in full.

The stakes are real, and they are not about Siri. The case targets OpenAI’s hardware programme, its attempt to build AI devices of its own, and the allegations involve the mechanics of how Apple designs hardware, its supplier relationships and its product roadmaps. The complaint names OpenAI, its hardware unit, its chief hardware officer and a former Apple engineer, and claims the company’s recruiting went after employees with access to Apple’s most sensitive projects. If the allegations are proven, they would amount to the most serious industrial espionage case in Silicon Valley in years. If they are not, they will look like an attempt by Apple to use the courts against a competitor it cannot beat in the market.

The timing is worth examining. The lawsuit landed in the middle of an escalating rivalry. OpenAI has spent the past two years building out a hardware strategy, hiring heavily from Apple and poaching executives with deep supply-chain experience, while Apple has been deepening its own AI push and, more quietly, negotiating with OpenAI’s competitors. Bloomberg reported in May that OpenAI was itself weighing legal action against Apple over their Siri partnership, which OpenAI believed had failed to deliver the promised integration and subscription revenue. Whatever the merits, both companies were already heading for a fight, and the lawsuit is the fight arriving in public.

The procedural rhythm now matters as much as the rhetoric. Apple’s injunction motion is set to be heard on 1 October, the same morning the court will hear OpenAI’s motion to dismiss, which argues that Apple never identified the trade secrets it says were taken. Between now and then come the written briefs, due 17 August and 24 August, in which both sides will argue the merits to the judge rather than to the press. A case that could be bound tight or thrown out on the same day, comfortably ahead of the hardware launch OpenAI is expected to make before the end of the year, concentrates everyone’s attention on the schedule.

The user-facing reality is calmer than the headlines. The lawsuit does not touch the ChatGPT integration on the iPhone, which remains in place, and Siri’s AI functions no longer depend on OpenAI anyway: Apple signed a multi-year deal with Google’s Gemini in January to power the rebuilt assistant. The fight is about hardware and talent, not about the software sitting in your pocket, and neither company has signalled any change to the consumer arrangement. That distinction is easy to lose in the coverage and worth keeping in mind while the motions pile up.

The longer view is that this case is the first big legal collision of the AI hardware era, and its outcome will shape how every company in the field hires, competes and litigates. If OpenAI’s hardware plans survive, the case reads as a warning shot that missed; if the injunction holds, it becomes a brake on the company’s most ambitious bet. What makes it worth watching is that both companies can survive a loss, and both have reasons to fight, which is exactly the combination that produces a long, expensive, precedent-setting case rather than a quick settlement.
