Apple Inc. has initiated a high-stakes legal battle against OpenAI, filing a comprehensive lawsuit that accuses the artificial intelligence powerhouse and several former Apple employees of a systematic effort to misappropriate confidential hardware trade secrets. The complaint, lodged in the U.S. District Court for the Northern District of California, alleges that OpenAI orchestrated a "pattern of theft" designed to jumpstart its nascent consumer hardware division by leveraging proprietary engineering processes, manufacturing techniques, and unreleased product specifications developed over years at Apple.
The lawsuit names OpenAI, its hardware-focused subsidiary io Products, and two high-profile former Apple staff members: Tang Tan, a former Vice President of Product Design, and Chang Liu, a former senior systems electrical engineer. According to the filing, these individuals played pivotal roles in a coordinated scheme to transfer Apple’s intellectual property to OpenAI, potentially saving the AI company years of research and billions of dollars in development costs as it seeks to move beyond software and into the physical device market.
A Coordinated Campaign for Intellectual Property
The core of Apple’s complaint centers on the allegation that OpenAI did not merely hire Apple talent but actively sought to acquire Apple’s internal technical blueprints. Apple claims that its former employees, under the direction or encouragement of OpenAI, downloaded thousands of highly sensitive documents before or immediately following their departures. These files allegedly included detailed engineering presentations, manufacturing specifications for unreleased hardware, and proprietary data related to Apple’s secretive hardware development cycles.
According to the legal documents, Apple first identified suspicious activity and raised concerns directly with OpenAI in February 2026. The Cupertino-based tech giant claims it requested an internal investigation by OpenAI to address the alleged misconduct and ensure that no Apple trade secrets were being utilized in OpenAI’s development pipelines. Apple asserts that OpenAI failed to respond to these inquiries, eventually necessitating the current litigation.
The complaint describes the situation as "the tip of the iceberg," suggesting that the identified theft by Tan and Liu may be part of a much broader effort involving hundreds of other former Apple employees who have migrated to OpenAI in recent years. Apple estimates that more than 400 of its former staff members are currently employed by the AI company, creating a significant channel for potential intellectual property leakage.
The Role of Tang Tan and io Products
At the center of the dispute is Tang Tan, who served as Apple’s Vice President of Product Design until his departure in 2024. Tan was a high-ranking executive with intimate knowledge of the hardware roadmaps for the iPhone and Apple Watch, two of the world’s most successful consumer electronics lines. Following his exit from Apple, Tan joined io Products, a hardware startup founded by legendary former Apple Chief Design Officer Sir Jony Ive.
The trajectory of io Products is central to Apple’s claims of a strategic hardware push by OpenAI. In 2025, OpenAI reportedly acquired io Products in a massive $6.5 billion deal. This acquisition not only brought Tang Tan into the OpenAI fold but also integrated over 50 specialized engineers, many of whom had prior experience at Apple. Apple alleges that Tan utilized his position at io Products and later OpenAI to recruit former colleagues, specifically targeting those with access to sensitive hardware data.
The lawsuit further alleges that during the recruitment process, Tan and other OpenAI recruiters encouraged Apple candidates to bring "actual parts," prototypes, and CAD (Computer-Aided Design) files to interviews for "show and tell" sessions. Apple claims Tan used internal Apple project codenames during these interviews to probe candidates for specific technical details about unreleased Apple products, effectively using the hiring process as a mechanism for industrial espionage.
Allegations of Post-Employment System Access
While Tang Tan is accused of orchestrating the broader strategy, Chang Liu is named as a primary actor in the physical theft of data. Liu, who spent eight years as a senior systems electrical engineer at Apple, is alleged to have exploited a security vulnerability to maintain access to Apple’s internal systems even after his employment had officially ended.
The complaint details how Liu allegedly downloaded confidential hardware files including engineering presentations and manufacturing documentation shortly before joining OpenAI earlier this year. Furthermore, Apple claims that Liu did not act alone in his technical efforts; the lawsuit alleges he instructed another Apple employee on how to bypass security protocols to copy confidential files without triggering internal alarms. This "instructional" element suggests a premeditated and collaborative effort to strip Apple of its proprietary assets before moving to a competitor.
Beyond the digital theft, Apple alleges that OpenAI used confidential supplier information—acquired through these former employees—to bypass traditional market barriers. The suit claims OpenAI approached longtime Apple manufacturing partners, requesting they perform work using proprietary production techniques that Apple had developed and funded, all without Apple’s authorization.
Official Statements and Responses
OpenAI has moved quickly to dismiss the allegations, framing the lawsuit as an attempt by a dominant incumbent to stifle competition in the emerging AI hardware space. In a statement shared on social media by Drew Pusateri, OpenAI’s Director of Strategic Communications, the company maintained its innocence.
"We have no interest in other companies’ trade secrets," the statement read. "We remain focused on building innovative technology that empowers people everywhere." OpenAI’s defense is expected to center on the argument that the skills and knowledge of the hired engineers are general professional expertise rather than protected trade secrets, and that the company has independent development paths for its hardware products.
Apple, conversely, emphasized the necessity of protecting the labor of its engineering teams. "At Apple, our teams are constantly developing breakthrough technologies to create the best products and services in the world, and protecting their work and intellectual property is something we take very seriously," an Apple spokesperson stated. The company is seeking both monetary damages and a permanent injunction to prevent OpenAI from using any of the allegedly stolen information in its products.
Context: The AI Hardware Arms Race
The legal confrontation comes at a critical juncture for OpenAI. Having dominated the generative AI software market with ChatGPT, the company is now looking to solidify its ecosystem through "AI-native" hardware. The acquisition of io Products and the partnership with Jony Ive were widely seen as the first steps toward a device that could potentially challenge the smartphone’s dominance by offering a more seamless, AI-driven user experience.
This is not the first time OpenAI’s hardware ambitions have landed the company in court. Earlier this year, a hardware startup named iyO brought separate trade secret allegations against OpenAI and its leadership, including CEO Sam Altman. That case resulted in a preliminary injunction, signaling that the judiciary is taking a close look at the aggressive talent and technology acquisition strategies employed by the AI giant.
The broader tech industry has seen similar high-stakes litigation before, most notably the Waymo v. Uber case, which involved the alleged theft of self-driving car secrets by a former Google engineer. Such cases often hinge on the "inevitable disclosure" doctrine and the forensic evidence of data transfers. For Apple, the challenge will be proving that the information taken provides OpenAI with a specific, unfair competitive advantage that could not have been achieved through independent research.

Industry Implications and Future Outlook
The outcome of this lawsuit could have profound implications for the Silicon Valley labor market and the future of AI hardware. If Apple succeeds, it could set a precedent that makes it significantly more difficult for AI companies to "poach" entire engineering teams from established tech giants. It could also lead to stricter security protocols and more aggressive enforcement of non-compete and non-disclosure agreements across the industry.
For OpenAI, a loss or a restrictive injunction could derail its hardware timeline, forcing the company to re-engineer core components of its upcoming devices to prove they do not rely on Apple’s intellectual property. This could give Apple more time to integrate its own advanced AI features into the iPhone and Apple Watch, maintaining its market lead.
As the case moves through the legal process, the discovery phase is expected to reveal more about the specific technologies OpenAI is developing. For now, the tech world remains focused on the Northern District of California, where the battle over the foundation of the next generation of consumer devices has just begun. The intersection of artificial intelligence and physical hardware is the new frontier of innovation, and as this lawsuit proves, it is also the new front in the war over intellectual property.
