Apple v. OpenAI: Trade Secret Claims and Employee Departures

Two named engineers, one filing in Northern California

Apple filed suit against OpenAI and io Products in the U.S. District Court for the Northern District of California on July 10, 2026, seeking injunctive relief and damages. The complaint names two former Apple employees: Tang Tan, a former vice president of product design who left in February 2024 to work with Jony Ive, and Chang Liu, a senior system electrical engineer with eight years at Apple who departed for OpenAI in January 2026. Apple says it first raised its concerns with OpenAI in February 2026 and received no response. [1]

The complaint alleges Tan used Apple's confidential project codenames during OpenAI job interviews, directed Apple job candidates to bring actual Apple hardware components to internal show and tell sessions, and possessed and distributed internal Apple security documents to new OpenAI hires before those hires had resigned from Apple. It alleges Liu exploited a security bug to download confidential engineering files after his departure, including more than 1,000 pages of circuit board manufacturing documents, and failed to return an Apple issued laptop. Apple's filing calls the conduct described "the tip of the iceberg" and says over 400 former Apple employees now work at OpenAI. [1]

Apple's later filings, through September 1, 2026, add that Liu downloaded a highly confidential Apple circuit schematic to his company issued MacBook, uploaded it to the circuit simulation program LTspice, and ran an AI agent against it. Apple says June 2026 messages between Liu and an OpenAI colleague, Yu-Ting Peng, discussed destroying the forensic data Apple would need to prove the theft, and Apple sought expedited discovery, including access to a Mac Mini Liu used, to head that off. OpenAI turned over Liu's laptop to investigators in August 2026. [2]

OpenAI calls the claims meritless

OpenAI has called Apple's claims meritless and argued they are motivated by Apple's own hiring difficulties and problems integrating AI into its products. On the allegation against Tan, OpenAI argues Apple has not identified a specific trade secret that was shared, which it says defeats a claim under the federal Defend Trade Secrets Act. OpenAI describes Liu's conduct as merely helping former Apple colleagues through their own departure procedures. [2]

Atlas interpretation: Apple's own framing in the filing goes further than the usual trade secret complaint about a document leaving the building. It argues that once confidential information is fed into an AI agent or model that learns from it, the resulting use of the secret becomes irreversible and self propagating, a claim built for an era when the alleged theft runs through a coding or simulation agent rather than a photocopier. Whether a court accepts that framing, rather than treating it as a description of ordinary misuse, is one of the things the case will test. [2]

The same talent gap that sent Apple to Google

Atlas interpretation: The lawsuit and Apple's decision six months earlier to license Gemini to run a rebuilt Siri rather than finish a frontier model of its own are not the same event, but they trace back to the same shortage. OpenAI's hardware effort, led by Jony Ive after its acquisition of Ive's io for roughly $6.5 billion, has pulled in more than 400 former Apple employees by Apple's own count, and Tan and Liu are only the two Apple chose to name. A company that cannot keep the engineers who know its hardware and cannot ship the model those engineers would have needed is dealing with one underlying problem described two different ways. [1]

Apple's public statement on the suit said, "At Apple, our teams are constantly developing breakthrough technologies, and we have a responsibility to protect their work and intellectual property. This is something we take very seriously, and we will pursue any means necessary to do so." [1]
