The tech world is abuzz with the news that Apple has filed a lawsuit against OpenAI, accusing the AI startup of trade secret theft. The legal battle pits the $4.6 trillion iPhone maker against the fast-growing AI company, marking a dramatic escalation in their relationship. At the heart of the dispute are allegations that former Apple employees, now working at OpenAI, systematically stole confidential data, including information about unreleased hardware products and technical specifications.
The lawsuit, filed in the Northern District of California court, names OpenAI, io Products, and two former Apple employees, Tang Tan and Chang Liu, as defendants. io Products, a hardware design firm acquired by OpenAI last year, was co-founded by Apple’s former design boss, Jony Ive. The complaint alleges that OpenAI’s nascent hardware business is built on a foundation of misappropriated trade secrets.
Key Allegations in Apple’s Lawsuit
Apple’s 41-page complaint outlines a series of shocking allegations against OpenAI and its employees. Tang Tan, OpenAI’s chief hardware officer and a former vice president at Apple, is accused of systematically stealing secrets. The complaint states that Tan used confidential Apple codenames during OpenAI’s recruiting process, encouraged interviewers to share secrets from the iPhone maker, and directed them to physically bring Apple hardware parts into interviews.
Chang Liu, a member of OpenAI’s technical staff, is accused of downloading dozens of confidential hardware files, including technical specifications, engineering presentations, and proprietary data for unreleased products. Liu is also accused of instructing an Apple employee on how to bypass security teams when copying files. OpenAI is accused of misappropriating knowledge of Apple’s supplier relationships and proprietary terminology to approach Apple’s supply chain partners.
The Background of the Dispute
The lawsuit comes at a time of transition for both companies. Apple CEO Tim Cook is set to hand the reins to John Ternus in September, while OpenAI prepares for an initial public offering. The partnership between Apple and OpenAI faded over time, and in January, Apple announced that it was turning to Google for its Apple Intelligence efforts.
OpenAI has been developing hardware devices designed to feature its AI tools, part of a strategy to control its own physical products rather than rely on giants like Apple. OpenAI has recruited from Apple, including hiring some of its top product leaders. In May 2026, OpenAI announced that it was buying Ive’s io Products for $6.4 billion. OpenAI CEO Sam Altman has made no secret that he envisions a new class of AI gadgets that replace smartphones as the primary consumer tech device.
The Implications of the Lawsuit
The lawsuit marks a significant moment in the tech industry, highlighting the intense competition and the high stakes involved in developing cutting-edge hardware and AI technologies. Apple is seeking a combination of injunctive relief, monetary damages, and declaratory judgments to stop the alleged theft. The outcome of this legal battle could have far-reaching implications for both companies and the tech industry as a whole.
This isn’t the first time OpenAI has faced such accusations. In 2026, the New York Times sued OpenAI and Microsoft, alleging that the companies used its articles and other content to train their AI models without permission. In June, a California judge dismissed a lawsuit from xAI, the company run by Elon Musk, alleging that OpenAI recruited a former xAI engineer to share information about the Grok chatbot.
