OpenAI has asked a federal judge to dismiss Apple's lawsuit accusing the AI company of stealing trade secrets, calling the allegations "meritless."
Lawyers for OpenAI said Apple's suit twists the actions of its employees. Bloomberg reports that the filing defends Chief Hardware Officer Tang Yew Tan, who spent 24 years at Apple as VP of product design for iPhone and Apple Watch before leaving to co-found io Products with former Apple design chief Jony Ive. io merged with OpenAI in July 2025. OpenAI said Tan followed normal industry recruiting practices when interviewing Apple staff.
OpenAI also defended senior systems engineer Chang Liu, one of two former Apple employees named in the suit. Apple claims Liu accessed confidential hardware files over several weeks after finding an authentication bug. OpenAI said Liu was simply helping a former Apple colleague find information for their own work, and published excerpts of text messages it says back up that account. "Apple should not be permitted to use a baseless and pretextual lawsuit," OpenAI's lawyers wrote.
OpenAI's motion argues Apple never properly identified what information actually counts as a protectable trade secret. The company said it has no interest in Apple's confidential material because it is "building something entirely new and different from anything at Apple."
Axios reported that OpenAI's filing also disputes how Apple built its case. According to OpenAI, Apple's own security practices, including letting staff use personal iCloud accounts for work and later reviewing personal messages left on company devices, are what gave former employees leftover system access in the first place, not evidence of a coordinated theft. The 31 page filing repeatedly frames the case as Apple trying to cover for its own struggles, with variations of the word "fail" appearing nearly 50 times.
OpenAI's filing also revisited an earlier dispute over how the two sides first fell out of contact. Apple's suit had claimed OpenAI never responded to its outreach in February, and that the two sides discussed the matter with OpenAI's general counsel. OpenAI says neither is true, and that the breakdown traced back to Apple's own outside counsel confusing two OpenAI employees with similar surnames and sending a message to the wrong person.
This week's motion follows the suit Apple filed against OpenAI in July, which accuses the company of running a scheme to pull confidential product information out of job candidates and new hires. Apple and OpenAI had spent about two years partnering to build ChatGPT integration into Siri, but the relationship soured as OpenAI moved into hardware, a shift accelerated by its acquisition of Ive's startup. Apple's suit claims more than 400 former Apple employees now work at OpenAI.
Apple escalated the case further this week, asking the same judge for a preliminary injunction to stop OpenAI from using any alleged trade secrets while the case continues, along with expedited discovery targeting Liu, Tan, OpenAI and its foundation, and io. Apple said its investigation has since turned up 11 more former employees who may have been witnesses or otherwise involved, beyond Liu, Tan, and previously named OpenAI employee Yu-Ting Peng.
Apple claims one former employee met with Liu and Peng before Peng's OpenAI interview and discussed proprietary information about unannounced products, and that another took screenshots of confidential documents relating to an unannounced Apple product before their own interview. Apple also said that after it filed its complaint, several former staffers now at OpenAI reached out about returning Apple issued devices they had kept.
OpenAI called that injunction request "based on false information and completely unnecessary" in a public blog post responding to Apple's filing. OpenAI has a court ordered deadline of August 17 to formally respond to Apple's preliminary injunction request. The judge is set to hear arguments on October 1.
