When Apple employees interviewed for jobs at OpenAI, the AI startup’s hardware head allegedly asked them to show up with something unusual: components they were working on and unreleased product samples. That’s according to a blockbuster lawsuit filed by Apple, which accuses OpenAI of stealing confidential documents, spying on hardware prototypes, and tricking one of its trusted partners into performing a proprietary product design technique.
The lawsuit primarily revolves around the alleged actions of three people:
- Tang Tan, a 24-year Apple veteran who recently served as the vice president of the Apple Watch. In 2024, Tan left to work on Jony Ive’s hardware company, io, which was acquired by OpenAI last year. OpenAI then appointed Tan as chief hardware officer.
- Chang Liu: A former Apple employee who worked as a systems electrical engineer on the iPhone for over eight years. Liu joined OpenAI in January 2026 as a member of technical staff.
- Yu-Ting “Alyssa” Peng: A former Apple employee who joined OpenAI in April 2026.
They’re accused of being part of an ongoing scheme to steal Apple’s secrets as OpenAI plans its first AI hardware device, which is supposed to be coming next year.
Here are the most surprising claims in Apple’s 41-page filing.
Liu allegedly kept an Apple-owned computer, allowing him to download dozens of confidential files
After announcing plans to leave Apple, Liu allegedly didn’t respond to requests to sign a confidentiality reminder, schedule an exit interview, or confirm that he returned company-owned devices, as is standard with departures at Apple. Instead, Apple claims Liu “failed to return at least one Apple-owned computer,” and told another employee, Peng, that he still has “another computer.”
Liu also allegedly accessed Apple’s cloud-based network storage weeks after he left the company, using an authentication vulnerability that Apple didn’t know about. “Mr. Liu celebrated his find with Ms. Peng and set about exploiting it: ‘LOL, I found out I can access the [network storage], so funny,’” Apple claims. “Ms. Peng’s response was immediate: “‘I’m ready.’”
Apple accuses Liu of downloading dozens of confidential files from its storage system, including documents containing technical specifications, details about unreleased products, and engineering presentations, including one detailing the manufacturing and testing of Apple’s main logic boards.
Peng is accused of siphoning confidential Apple information to Liu
In the months following Liu’s departure, Peng allegedly kept Liu in the loop about Apple’s projects, engineering details, and vendor relationships. “Ms. Peng and Mr. Liu would engage in depth about those confidential projects, while Mr. Liu was working on developing OpenAI’s competing hardware,” Apple claims. “Mr. Liu’s work for OpenAI was informed by a steadily flowing stream of Apple’s trade secret information from Ms. Peng.”
Apple also claims that Liu informed Peng on how to access and copy files from Apple’s devices “to avoid trouble with the security team,” while pointing her to “specific Apple project folders and proprietary engineering data.” Peng departed Apple for OpenAI in April 2026.
OpenAI’s hardware head allegedly digs for confidential Apple projects during interviews
Tan is accused of soliciting Apple’s trade secrets during interviews with OpenAI job candidates — and quizzing them on it. Apple claims Liu told Peng about how another former Apple employee “fumbled” his answers to a question Tan asked about “a top-secret project for an unreleased new Apple product.” Liu then allegedly downloaded “some info” using his access to Apple’s network to help Peng prepare for her interview.
In another instance, Apple claims another former employee began “screenshotting and downloading files relating to a highly confidential Apple project” before an interview with OpenAI. Tan is accused of asking for more information about that same project during the interview. Last year, Tan admitted to receiving confidential information about an AI hardware startup before joining Ive’s io.
Tan asks former Apple employees to share parts and product samples for “show and tell”
Aside from asking for more information about Apple’s secret projects, Tan is accused of telling interviewees to bring hardware components and product samples from their work at Apple for “show and tell sessions:”
For example, messages left on an Apple-issued work device show that Mr. Tan instructed an Apple employee to “bring some parts [she] worked on” such as “Batteries,” “SIP” (Systems-in-Package), “mlb” (multi-layer or main logic boards), and “shields” and that it may “be good to show” other interviewers these Apple components.
Additionally, OpenAI is accused of asking interviewees to prepare “Technical Deep Dive” presentations, with slides revealing confidential information from their work at Apple.
OpenAI allegedly “coached” Apple employees on how to bypass security measures
Apple claims Tan kept an internal document that outlines employee offboarding procedures. OpenAI allegedly used this information to warn employees coming from Apple about the company’s security checks, and “coached” them on how to avoid it.
The AI giant also advised departing Apple workers not to disclose their new employer, and also offered tips on how to avoid a “dreaded walk out,” which would result in their immediate removal from the company, preventing them from accessing Apple’s systems for a standard two weeks, the lawsuit alleges. OpenAI is accused of telling Apple employees not to “sign anything at the exit interview,” and if they’re asked to sign a document, to tell OpenAI “asap.”
In the lawsuit, Apple says that OpenAI’s alleged tactics “appear to be having their desired effect.” Apple claims it has noticed “a recent trend of employees who are leaving Apple for OpenAI and taking steps to evade security measures,” including workers “ignoring outreach by security personnel to schedule exit processes and security reviews.”
Apple accuses OpenAI of stealing its metal-finishing technique
Apple claims OpenAI has used its confidential information to approach its “trusted partners,” including one that carries out a proprietary, multi-step metal-finishing technique for its products. OpenAI allegedly misled Apple’s partner, making the company believe that OpenAI had Apple’s permission to use the metal-finishing technique. “Apple has not given OpenAI or io permission to use or a license to any of Apple’s trade secrets or confidential information, including those it has entrusted with this partner,” Apple says.
Apple also accuses OpenAI of approaching “at least” one other supplier that works with Apple on manufacturing related to power and batteries. OpenAI allegedly used confidential information and internal codenames to ask “targeted questions” about Apple’s components “that would be useful in furthering OpenAI’s hardware ambitions.”
OpenAI spokesperson Drew Pusateri provided this statement to The Verge on Friday: “We have no interest in other companies’ trade secrets. We remain focused on building innovative technology that empowers people everywhere.”
