Apple Lawsuit Filing Accuses OpenAI of Stealing Trade Secrets

Apple filed a lawsuit against OpenAI on Friday in a California federal court, alleging that former employees stole trade secrets tied to hardware development and handed that knowledge to OpenAI's device team. The apple lawsuit filing marks a sharp escalation between two companies that have spent the past two years as AI partners rather than adversaries.

What the Apple Lawsuit Filing Actually Alleges

Apple's complaint frames the matter as institutional, not incidental. The filing describes a "coordinated pattern of misconduct at an institutional level" and centers on two named individuals: Tang Tan, who worked on the iPhone, Apple Watch and iPod before becoming OpenAI's chief hardware officer, and Chang Liu, a former Apple electrical engineer who Apple says had access to sensitive product development work before joining OpenAI earlier this year.

The specific allegations are granular. Apple claims Liu accessed and downloaded confidential hardware files using an Apple issued device he retained after leaving the company. Separately, Apple alleges Tan told job candidates still employed at Apple to bring "actual parts" to their OpenAI interviews. Apple says it opened an internal investigation, found what it calls a pattern of theft, and reached out to OpenAI in February to flag the concerns, only to get no response. OpenAI has not commented on the suit.

Numbers Behind the Hardware Push

The financial scale of OpenAI's hardware ambitions gives the dispute weight beyond a personnel spat. OpenAI's acquisition of io Products, the hardware venture co founded by former Apple design chief Jony Ive along with Tan and two others, was valued at nearly 6.5 billion dollars. That figure signals how much capital OpenAI has already committed to a device business that, per Apple's filing, now rests on what the company calls "the shakiest of foundations."

• io Products acquisition value: nearly 6.5 billion dollars
• Apple OpenAI partnership start: 2024, integrating ChatGPT into Siri as an answer engine
• Apple's outreach to OpenAI over concerns: February 2025, described as unanswered
• OpenAI hardware timeline, per CFO Sarah Friar in April: consumer device expected by late 2025

From Integration Partner to Direct Competitor

Apple turned to OpenAI a few years back after finding itself behind in the generative AI race that ChatGPT ignited. The 2024 deal let ChatGPT function as a fallback answer engine on iPhones when Siri came up short. That arrangement has not aged into deeper cooperation. Instead, OpenAI recruited Ive to lead a hardware effort many analysts view as a potential rival to Apple's own device lineup, a project OpenAI has publicly described only as a new way to interact with AI beyond "traditional products and interfaces."

That ambiguity has not stopped comparisons to prior attempts at ambient AI hardware. Amazon and Google pushed screen free voice assistants into households roughly a decade ago, and OpenAI's project is widely read as an attempt to leapfrog that generation of devices with something built around large language models rather than fixed voice commands.

A Tangled Web of Related Litigation

Apple's suit does not exist in isolation. A separate case already pits a lesser known startup, iyO Inc., against Ive and OpenAI CEO Sam Altman over trademark infringement, stemming from the similarity between iyO's name and io Products along with prior business contact between the parties. iyO has also sued one of its own former employees over an alleged leak of a confidential product drawing, and later folded in trade secret claims against Tan specifically.

Apple's new filing names io Products itself as a defendant alongside Tan and Liu, layering a third active dispute onto a hardware project that has yet to ship a single unit. Lawyers previously representing io Products and Tan did not respond to requests for comment on Apple's suit.

Where This Leaves OpenAI's Device Ambitions

The timing cuts against OpenAI on two fronts. The company has been weighing a path toward a public listing, and it already contends with intensifying competition from Anthropic and Google on the model side. OpenAI trimmed several side projects earlier this year to refocus on ChatGPT, yet Friar's April comment that consumer hardware would arrive by the end of 2025 suggests the device remains a priority. Whether that timeline survives a trade secret fight that questions the foundation of the hardware team itself is the question Apple's filing now puts squarely on the table.
