In a dramatic fallout between former partners, Apple has filed a major federal lawsuit against OpenAI.
The complaint, filed in the U.S. District Court for the Northern District of California, accuses OpenAI of executing an institutional campaign to misappropriate Apple’s trade secrets and corporate intellectual property. The lawsuit alleges that OpenAI sought to accelerate its own consumer hardware initiatives by poaching talent and acquiring confidential engineering data from Cupertino.
What the Lawsuit Alleges
According to the 41-page legal filing, Apple claims that OpenAI’s upcoming hardware division rests on a “foundation of theft”. The complaint targets not only OpenAI, but also its hardware division io Products and two high-profile former Apple employees:
Tang Tan: Former Apple Vice President of Product Design (iPhone/Apple Watch) and current Chief Hardware Officer at OpenAI.
Chang Liu: Former senior systems electrical engineer at Apple.
Apple's Key Allegations:
├── Show-and-Tell Interviews: Candidates instructed to bring confidential Apple parts.
├── Post-Departure File Access: Ex-employees downloading confidential engineering files.
├── Corporate Mentorship: Coaching recruits on retaining system permissions upon exit.
└── Exploitation of Supply Chains: Replicating hardware R&D using leaked supplier data.
1. “Show-and-Tell” Job Interviews
Apple alleges that during recruitment interviews for OpenAI’s hardware team, incoming candidates—who were still actively employed at Apple—were asked to bring physical components, circuit boards, and unreleased prototype samples for demonstration.
2. Post-Departure Network Intrusion
The lawsuit highlights the case of Chang Liu, who allegedly failed to return a company laptop after quitting Apple. Apple claims Liu exploited a security loophole to log back into internal networks while already working at OpenAI, downloading over 1,000 pages of confidential hardware files, unreleased specs, and engineering presentations.
3. Exit Strategy Coaching
Apple alleges that OpenAI leadership actively mentored departing Apple engineers on how to bypass security protocols, delay handing over devices, and maintain access privileges to internal servers for as long as possible.
From Apple’s Court Complaint:
“OpenAI’s nascent hardware business now rests on the shakiest of foundations, rotten to its core by its illegal reliance on misappropriated trade secrets.”
From Partners to Rivals: How the Relationship Fractured
The legal action marks a total collapse in relations between the two tech giants:
| Milestone | Event |
| 2024 Partnership | Apple partners with OpenAI to integrate ChatGPT into iOS and Siri. |
| 2025 Hardware Push | OpenAI acquires Jony Ive & Tang Tan’s io Products for ~$6.5 billion to build AI hardware. |
| Early 2026 Warning | Apple warns OpenAI in February about data theft; receives no response. |
| July 2026 Lawsuit | Apple files federal suit seeking damages, injunctions, and destruction of stolen data. |
OpenAI’s Response & Future Outlook
In response to the filing, an OpenAI spokesperson rejected the claims, stating:
“We have no interest in other companies’ trade secrets. We remain focused on building innovative technology that empowers people everywhere.”
What This Means for the AI Industry
Complications for OpenAI’s IPO: The legal battle could create significant friction for OpenAI as it prepares for a highly anticipated public offering.
Siri Pivot: The lawsuit reinforces reports that Apple is shifting its primary AI integration away from ChatGPT in favor of alternatives like Google’s Gemini.
Hardware Ambitions on Hold: An injunction could delay or halt OpenAI’s physical device launch alongside design studio partners.
