A 41-page federal lawsuit and dozens of preservation letters signal Apple is treating OpenAI's hardware push as an intellectual property threat worth going nuclear over.
Apple just fired a legal broadside at OpenAI, and the shrapnel is landing on roughly 40 former Apple employees who made the jump to Sam Altman’s empire. The iPhone maker sent preservation letters to those individuals, demanding they safeguard documents and communications, and requesting sit-downs with Apple’s legal team.
This isn’t a polite corporate disagreement. It’s a 41-page federal complaint filed in the Northern District of California that Apple itself describes as just the “tip of the iceberg.”
What Apple is alleging #
The lawsuit, filed on July 10, names OpenAI, its hardware affiliate io Products, and two specific former Apple employees: Tang Yew Tan and Chang Liu. Apple’s core claim is that OpenAI orchestrated a systematic campaign to siphon proprietary hardware designs and manufacturing processes from departing Apple staff.
The individual accusations are remarkably specific. Tan is alleged to have instructed job candidates to physically bring proprietary Apple parts to their interviews. Liu’s alleged conduct is a different flavor of alarming. According to the complaint, Liu exploited a security bug to download files after he had already joined OpenAI earlier this year.
About a week after filing suit, Apple escalated further. On July 17, those preservation letters went out to approximately 40 of the more than 400 former Apple employees currently working at OpenAI.
Why this matters beyond Silicon Valley turf wars #
More than 400 former Apple employees now work at OpenAI. The 40 individuals who received preservation letters represent roughly 10% of that group, which implies Apple’s legal team has already identified specific threads worth pulling.
OpenAI’s hardware ambitions have been an open secret for months. The io Products affiliate is the vehicle for that strategy. Apple’s complaint paints a picture where OpenAI didn’t just hire experienced hardware engineers, but actively encouraged them to smuggle out the playbook.
Apple and OpenAI previously enjoyed a partnership that included the integration of ChatGPT into Apple devices. The lawsuit filed on July 10, 2026, reflects a significant escalation in these tensions, with Apple accusing OpenAI of orchestrating systematic efforts to siphon off intellectual property from Apple by targeting its former employees.
