Apple released a new court filing pushing back on OpenAI’s latest trade-secret accusations, claiming the claims aren’t part of the core lawsuit and were filed without prior notice. Apple says the involved engineer briefly moved to OpenAI and then back to Apple, and that its investigation found no OpenAI confidential data.

The case isn’t settled yet. The court will decide how these separate claims relate to the main dispute, and more filings could come from either side.

  • OpenAI alleges a former Apple employee carried confidential files to personal accounts.
  • Apple argues the new claims are unrelated to the main case and filed without notice.
  • The engineer returned to Apple after a stint at OpenAI; no OpenAI confidential data was found in Apple’s review.

Apple has sent a new court filing pushing back on OpenAI’s recent trade-secret allegations, arguing the fresh claims are not connected to the main lawsuit and were raised without advance notice to Apple.

Here’s the context: earlier this year Apple filed a suit alleging misappropriation of trade secrets, naming two former employees, OpenAI and io Products. OpenAI later claimed a former Apple engineer who moved to OpenAI carried confidential files about an unreleased OpenAI device to personal accounts. Apple says it began investigating as soon as the matter was raised and found no evidence that any OpenAI confidential information was involved.

In its new filing, Apple emphasizes that OpenAI’s accusations were disclosed in court without giving Apple a chance to respond first, and it argues the new claims should be treated separately from the central misappropriation case.

Apple also reveals that the engineer at the heart of the dispute initially left Apple for OpenAI but later returned to Apple. The company explains the engineer held the same Manufacturing Design role both before and after the switch and notes that Apple’s check found no OpenAI confidential material in the engineer’s accounts. Apple requests more precise information to continue examining the issue, but OpenAI did not provide it before pushing the docket forward, according to Apple.

“Apple will continue to work with OpenAI to get to the bottom of these allegations,” the filing states, and Apple says it is taking steps to preserve relevant evidence as required by law while it reviews the new material. The company also reiterates that the new assertions do not alter the core dispute about OpenAI allegedly misusing Apple confidential information.

The public dispute between Apple and OpenAI underscores how seriously both sides guard sensitive tech information when employees move between companies. The latest filing appears to seek clarity on how these separate accusations relate to the main case and whether the court will require further evidence from either side.
