Apple Sues OpenAI Over Alleged Hardware Trade Secret Theft

Key Takeaways

• Apple initiated legal action against OpenAI in California federal court, claiming trade secret misappropriation and contractual violations
• Tang Yew Tan, ex-hardware executive at Apple, is accused of transferring supplier information and instructing candidates to bring confidential Apple components to job interviews
• Chang Liu, a former Apple engineer, allegedly retained company equipment after departure and accessed sensitive files
• OpenAI reportedly demonstrated Apple’s exclusive metal-finishing process to a third-party manufacturer without authorization
• Industry experts suggest the litigation may hinder OpenAI’s consumer device roadmap and strain its collaborative ties with Apple

The Cupertino-based tech giant launched legal proceedings against OpenAI this past Friday, alleging systematic theft of confidential information and violation of existing agreements. The complaint was submitted to the U.S. District Court for the Northern District of California.

The legal action marks a dramatic shift in relations between the two technology leaders, who established a collaborative arrangement in 2024 integrating ChatGPT functionality into iOS. This partnership has now devolved into courtroom confrontation.

The Allegations in Detail

At the heart of Apple’s complaint stands Tang Yew Tan, who spent nearly a quarter-century at the iPhone maker working on design initiatives for flagship products including the iPhone and Apple Watch. Tan later established io Products, a hardware development firm that OpenAI purchased for approximately $6.5 billion last year.

According to the filing, Tan systematically transferred sensitive supplier data to his private email account during his final days at Apple. The lawsuit further claims he provided guidance to prospective OpenAI hires on circumventing Apple’s exit protocols and explicitly directed interview candidates to transport unreleased Apple components—such as battery systems, circuit boards, and integrated System-in-Package technology—to OpenAI facilities as demonstration materials.

The complaint also names Chang Liu, who served as a senior systems electrical engineer at Apple. The filing asserts Liu retained an Apple-issued computing device following his transition to OpenAI and subsequently utilized it to extract proprietary technical documentation.

A third accusation centers on manufacturing processes. Apple contends that OpenAI showcased a confidential metal surface treatment methodology to an external manufacturing collaborator while falsely implying Apple had granted permission for such disclosure.

OpenAI has categorically rejected these accusations. In an official response, the company stated: “We have no interest in other companies’ trade secrets.”

Implications for OpenAI’s Device Strategy

The timing of this lawsuit is particularly significant for OpenAI’s broader ambitions. The artificial intelligence company has publicly acknowledged its intention to enter the consumer hardware market, with industry sources describing products including a screenless wearable device and an intelligent camera-enabled speaker system. Development timelines for certain products have reportedly shifted into early 2027.

The legal process will now grant Apple extensive access to OpenAI’s hardware development operations during a pivotal phase. Should Apple secure preliminary injunctive relief, it could effectively halt progress on OpenAI’s entire device initiative.

Industry analyst Paolo Pescatore commented to Reuters: “Even if the allegations are not proven, the lawsuit could delay OpenAI’s hardware ambitions and further weaken what is already becoming an increasingly fragile partnership.”

The legal battle also coincides with a major transition in Apple’s executive structure. Tim Cook is scheduled to assume the role of executive chairman on September 1, transferring CEO responsibilities to John Ternus, who currently oversees hardware engineering operations.

Apple’s legal filing requests judicial intervention to prevent OpenAI from retaining or utilizing any allegedly misappropriated materials and demands their immediate return.

Legal proceedings are anticipated to extend through multiple procedural phases in the coming months. Despite their current dispute, both organizations recognize a fundamental truth: the battle to define the next generation of consumer computing platforms is unfolding in real time.
