[Apple accuses OpenAI of "destroying evidence" and claims former engineers "took away secrets and used them in OpenAI"] On September 1, it was reported that Apple's legal battle against OpenAI has escalated. In new court documents, OpenAI claimed that OpenAI "actively destroyed key evidence" and that Chang Liu, a former iPhone engineer who quit OpenAI, "not only downloaded Apple's confidential circuit schematics, but also used them in OpenAI's work." This court written document was submitted on August 31, local time, to support Apple’s motion to expedite pretrial fact-finding. Apple accused OpenAI of stealing trade secrets, and the latter asked the court to dismiss the case.
