TLDR
- Apple initiated legal proceedings against OpenAI in California’s Northern District, claiming misappropriation of proprietary information and contractual violations
- Tang Yew Tan, previously heading Apple’s hardware division, purportedly transmitted sensitive supplier information and instructed interview candidates to present unreleased Apple technology
- Chang Liu, a former engineer, allegedly retained Apple property after his departure and accessed confidential materials
- 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 device development timeline and strain its existing business relationship with Apple
In a significant legal development, Apple initiated federal litigation against OpenAI last Friday, charging the artificial intelligence firm with misappropriating confidential business information and violating contractual obligations. The complaint was lodged in California’s Northern District federal court.
The collaboration between these technology powerhouses began in 2024 when Apple integrated ChatGPT functionality directly into iOS. This once-cooperative arrangement has now evolved into contentious litigation.
Apple’s Allegations Detailed
At the heart of Apple’s complaint stands Tang Yew Tan, who spent nearly a quarter-century at Apple working on critical product design for iPhone and Apple Watch devices. He subsequently established io Products, a hardware development firm that OpenAI purchased for approximately $6.5 billion in 2025.
According to Apple’s filing, Tan transmitted confidential supplier data to his private email account prior to his resignation. The complaint further alleges he provided guidance to prospective employees on navigating Apple’s exit protocols and instructed job applicants to present unreleased Apple components—including power cells, circuit boards, and integrated package systems—during OpenAI interviews as demonstration materials.
The lawsuit also names Chang Liu, who served as a senior electrical systems engineer. Apple contends Liu retained company-issued computing equipment after transitioning to OpenAI and subsequently utilized it to extract sensitive technical documentation.
Additionally, the complaint addresses a specialized manufacturing method. Apple maintains that OpenAI revealed its proprietary metal surface treatment technique to an external production partner while creating the impression that Apple had granted permission for this disclosure.
OpenAI has categorically rejected these accusations. “We have no interest in other companies’ trade secrets,” the organization stated in its official response.
Implications for OpenAI’s Device Strategy
This legal action comes at a particularly crucial juncture for OpenAI. The company has publicly announced intentions to launch its inaugural consumer hardware product, with industry reports suggesting a screen-free wearable device and an intelligent camera-enabled speaker. Production schedules for certain products have already been pushed to early 2027.
The litigation will now expose OpenAI’s hardware development operations to legal scrutiny during this pivotal development phase. Should Apple secure a preliminary injunction, it could effectively halt progress on the entire device initiative.
Industry analyst Paolo Pescatore told 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 timing coincides with a significant transition in Apple’s executive structure. Tim Cook will assume the role of executive chairman on September 1, transferring chief executive responsibilities to John Ternus, who currently leads Apple’s hardware engineering operations.
Apple’s legal petition requests the court to prohibit OpenAI from retaining or utilizing any allegedly misappropriated materials and to mandate their complete return.
Legal proceedings are anticipated to continue through multiple procedural stages. Despite their adversarial positions, both corporations acknowledge a shared understanding: the competition to define the next generation of consumer computing devices is unfolding in real-time.
