At a Glance
- Apple filed a 41-page federal trade secret lawsuit against OpenAI, its hardware division io Products, and two former Apple employees.
- The complaint alleges that OpenAI’s Hardware Chief Tang Tan and engineer Chang Liu improperly accessed, exfiltrated, and used proprietary hardware design and supply chain files.
- OpenAI denied all allegations, asserting its focus remains on independent innovation and supporting standard employee mobility.
Introduction
Apple has launched a major legal action against OpenAI, marking a sharp operational conflict between two companies that previously maintained a high-profile integration partnership. Filed in the U.S. District Court for the Northern District of California, the lawsuit accuses the AI research firm of orchestrating an intentional campaign to acquire proprietary hardware blueprints, supplier pricing structures, and advanced manufacturing processes from Apple.
The action highlights growing competitive friction as frontier AI developers transition from purely software-based model deployment into custom consumer hardware. The dispute centers on OpenAI’s hardware group—formed in part through its acquisition of io Products—and former Apple engineering leaders who transitioned to the AI company.
What Happened
According to court filings, Apple alleges that OpenAI built its consumer hardware organization by systematically recruiting key engineering personnel and extracting protected design data. The lawsuit names OpenAI, its hardware subsidiary io Products, and two specific individuals: Tang Yew Tan (OpenAI’s Chief Hardware Officer and former Apple VP of Product Design) and Chang Liu (a former senior electrical engineer at Apple).

The complaint outlines distinct allegations regarding how proprietary information was allegedly acquired:
- Interview Demonstrations: Apple claims that Tang Tan instructed prospective hires during OpenAI interview cycles to bring physical, unreleased Apple hardware components for hands-on evaluation.
- Network Exploitation: The suit alleges that Chang Liu leveraged a network authentication flaw following his resignation to exfiltrate confidential engineering presentations, manufacturing specifications, and supplier contracts using an unreturned corporate laptop.
- Supply Chain Misrepresentation: Apple further claims OpenAI contacted contract manufacturers to request proprietary metal-finishing techniques by falsely representing that Apple had sanctioned the process sharing.
OpenAI has rejected the claims. In an official response, OpenAI stated that the company has no interest in third-party trade secrets and builds its technologies independently. Executives emphasized that former Apple employees are exercising standard professional mobility, which is protected under California labor standards.
Key Details
The legal filing documents a series of specific operational metrics, timelines, and technical claims:
- Jurisdiction: U.S. District Court for the Northern District of California.
- Primary Corporate Defendants: OpenAI, Inc. and io Products, Inc. (acquired by OpenAI for approximately $6.5 billion).
- Named Individual Defendants: Tang Yew Tan (Chief Hardware Officer, OpenAI) and Chang Liu (Technical Staff, OpenAI).
- Evidence Assertions: Apple alleges over 1,000 pages of internal manufacturing specifications were improperly downloaded alongside confidential supplier contact directories.
- Protective Legal Actions: Legal preservation notices have been issued to approximately 40 former Apple engineers currently employed at OpenAI.
Why This Matters
This suit represents the first major trade secret litigation where a legacy consumer electronics giant directly targets an AI developer’s hardware ambitions. As large language models reach parity across software interfaces, physical form factors—such as ambient home devices, smart wearables, or dedicated AI companions—represent the next primary distribution channel for enterprise AI labs.
For the tech ecosystem, the case draws a sharp line regarding talent acquisition practices in Silicon Valley. California law strongly favors worker mobility and invalidates non-compete clauses; however, trade secret laws explicitly prohibit the transfer of proprietary technical assets, source files, or physical prototypes to a new employer.
Background
The litigation arrives despite a previous commercial arrangement established in 2024 to integrate OpenAI’s ChatGPT directly into Siri and Apple Intelligence workflows. Apple explicitly noted in its filing that the lawsuit does not impact that software integration agreement, treating product licensing and IP protection as distinct operational matters.
Tensions have grown since OpenAI completed its $6.5 billion acquisition of io Products, the hardware venture co-founded by former Apple Chief Design Officer Sir Jony Ive. Over 400 former Apple employees have joined OpenAI across various software, systems, and hardware divisions, creating significant talent overlap between the two firms.
Tech Insight
Building custom consumer hardware requires years of capital investment, supplier qualification, and thermal/mechanical engineering validation. By targeting specialized manufacturing processes—such as custom alloy finishes, compact PCB layouts, and component density techniques—an emerging hardware player can bypass years of failure testing and prototype iterations.
Standard Hardware Lifecycle:

Accelerated Path via Alleged Exfiltration:

Apple’s legal strategy aims to protect its physical supply chain advantage. If Apple successfully secures preliminary injunctions preventing OpenAI from utilizing contested design principles or working with specific contract lines, OpenAI’s physical hardware roadmap could face multi-year delays.
What to Watch Next
Hardware Launch Timelines: Industry analysts will monitor whether ongoing litigation alters OpenAI’s projected schedule for announcing its inaugural consumer AI hardware device.
Preliminary Injunction Motions: Observers are tracking whether Apple files for an immediate injunction to freeze hardware development pipelines at io Products pending full discovery.
Discovery Filings: Court-ordered forensic audits of digital storage devices retained by the named individual defendants will determine whether data transfer actually occurred.
