OpenAI answers Apple's trade-secrets suit with a claim that an ex-employee moved 100-plus device files
OpenAI alleges an ex-employee now at Apple sent more than 100 files on an unreleased device to a personal account. Apple, which sued OpenAI in July, says it found no evidence, so each company now faces untested allegations from the other.

What happened
- OpenAI further alleges the employee later made a presentation on the unreleased product to Apple's senior leadership, and it places that presentation months ago.
- Apple's July complaint in San Jose names OpenAI, its hardware unit io Products, Tang Yew Tan and former Apple engineer Chang Liu as defendants.
- Apple alleges Liu, after leaving the company in January 2026, exploited an authentication bug to download confidential files.
- The material Apple says is at issue includes hardware files, engineering presentations and supplier information.
Why it matters
- exposure OpenAI's allegation puts Apple's senior leadership in the room for the presentation, so what was shown and when becomes a question the case has to answer.
- capability OpenAI can now argue that leakage ran in both directions, a position it did not have while it was mostly answering Apple's complaint.
- decision Apple has to choose between resting on its denial and producing development records for HomeView, and the months-versus-this-week timing makes the records the stronger answer.
OpenAI's theory of harm is use. "OpenAI is very concerned that its trade secret and confidential information is now circulating inside Apple, where Apple engineers can shape Apple's upcoming products based on OpenAI's confidential and innovative work," the company said in its filing [8]. Two links have to hold: the presentation carried OpenAI material, and an Apple product changed because of it. For the second, OpenAI cites the release of Apple's HomeView product this week [7], while placing the presentation itself months ago [2]. We think that timing gap is where OpenAI's theory is weakest. Apple says it has policies and procedures to keep new employees from using a previous employer's confidential information [9]. If OpenAI can show HomeView changed after the presentation, we are wrong.
The counter-thesis is that the filing pays off even if the HomeView link fails. CryptoBriefing wrote that OpenAI had been mostly on defense and is now arguing that leakage also flowed toward Apple [15], an argument that arrived about three months after Apple's July complaint [18]. OpenAI denies wrongdoing and, according to CryptoBriefing, has framed Apple's claims as the product of Apple's own mismanagement [6]. Both sets of allegations are untested in court [5].
The exposure on OpenAI's side is a purchase price and a schedule. It paid about $6.5 billion for io Products in 2025 [12] and has reportedly hired more than 400 former Apple employees across various projects [13]. Tang Yew Tan, a named defendant in Apple's suit, leads a group that includes multiple ex-Apple engineers working on the hardware [14]. The first device, an AI companion product, is expected in late 2026 or 2027 [19]. The $6.5 billion pays off only if that device ships in that window. A case that can claim the time of the man leading the group building it is a cost to the schedule.
Apple's records could show the presentation held nothing of OpenAI's. That would leave a filing that drew attention and little else. The documents could show the opposite, and CryptoBriefing has already called the claim awkward for a company whose brand rests on secrecy and tight control over unreleased products [16]. Or the allegations stay untested past the device's unveiling window [19].
What to watch
- Whether Apple produces records showing when HomeView's design was fixed relative to the presentation OpenAI says took place months ago.
- How the San Jose court handles OpenAI's new filing alongside Apple's July complaint, including any dispute over the presentation's date and content.
- Whether OpenAI's AI companion device is unveiled in late 2026 or slips into 2027 while the case is open.
