Apple files a major federal lawsuit against OpenAI, alleging a systemic, employee-led campaign to steal hardware trade secrets for its upcoming consumer devices.
The corporate partnership that briefly defined the AI smartphone era is officially dead. In a stunning legal escalation, Apple Inc. has filed a major federal lawsuit against OpenAI, accusing the artificial intelligence giant of orchestrating a coordinated, highly aggressive campaign of industrial espionage. The complaint alleges that OpenAI systematically poached senior engineering talent and coaxed them into exfiltrating tightly guarded trade secrets to accelerate its own secretive consumer hardware roadmap.
The legal bombshell was filed in the U.S. District Court for the Northern District of California. The lawsuit names OpenAI, its hardware subsidiary io Products, OpenAI Chief Hardware Officer Tang Yew Tan, and former senior systems electrical engineer Chang Liu as primary defendants. The move marks an abrupt collapse in relations between two tech giants that integrated ChatGPT directly into Apple’s operating systems just two years ago.
“Show and Tell” via Corporate Codenames
The core of Apple’s complaint targets Tang Yew Tan, a 24-year Apple veteran who previously served as the Vice President of Product Design for the iPhone and Apple Watch. Tan left the iPhone maker to spearhead OpenAI’s physical device ambitions following OpenAI’s massive $6.5 billion acquisition of Jony Ive’s design firm, io Products, in 2025.
According to court filings, Apple alleges that Tan actively weaponized his intimate knowledge of internal operations during OpenAI’s recruitment drives. The suit claims Tan utilized highly confidential internal Apple project codenames while interviewing prospective hires. More egregiously, the complaint states that Tan explicitly instructed Apple job applicants to bring actual physical components from Apple’s design laboratories to present during “show and tell” sessions at OpenAI job interviews.

The Network Exploitation Allegations
While the allegations against Tan focus on corporate poaching tactics, the technical charges leveled against engineer Chang Liu border on criminal hacking. Liu left Apple in January 2026 to join OpenAI’s engineering division.
Apple legal teams assert that Liu intentionally failed to return his corporate-issued laptop upon resignation. The filing details that Liu subsequently discovered a rare, unmonitored authentication vulnerability within Apple’s internal enterprise servers after his termination date. Instead of reporting the bug, Liu allegedly exploited the flaw to download over 1,000 pages of highly sensitive manufacturing blueprints, proprietary metal finishing techniques, and upcoming product timelines, even messaging a current Apple employee to boast about the backdoor access.
As reported by The Guardian, Apple’s legal filing pulls no punches, declaring that OpenAI’s upcoming hardware unit “now rests on the shakiest of foundations, rotten to its core by its illegal reliance on misappropriated trade secrets.”
OpenAI spokesperson Drew Pusateri quickly issued a formal rejection of the claims:
“We have no interest in other companies’ trade secrets. We remain focused on building innovative technology that empowers people everywhere.”
A High-Stakes Battle Over Post-Smartphone Silicon
The timing of Apple’s lawsuit is far from accidental. OpenAI is currently laying the groundwork for a highly anticipated initial public offering (IPO) targeting a valuation near $850 billion. Simultaneously, OpenAI is reportedly weeks away from unveiling its first standalone consumer device, an AI-agent-centric physical keyboard and communication interface developed alongside legendary designer Jony Ive.
Industry analysts at Semafor suggest that Apple is deploying its strongest legal levers to freeze OpenAI’s hardware momentum before it can threaten the iPhone ecosystem. If the court grants the permanent injunctions and punitive damages Apple is demanding, it could legally block OpenAI from manufacturing any hardware derived from the disputed intellectual property, effectively resetting its hardware pipeline.
With more than 400 former Apple employees now identified on OpenAI’s payroll, the litigation promises an intense, lengthy discovery process. As the tech industry transitions from apps to physical ambient AI agents, the trial stands as a monumental showdown defining the legal boundaries of talent acquisition and corporate engineering in the post-smartphone era.
