Apple is escalating its trade secrets lawsuit against OpenAI by requesting expedited discovery and a preliminary injunction. The core claim: former Apple employees—specifically Chang Liu and Tang Yew Tan—shared confidential information about unannounced products with OpenAI. Apple's latest filing expands the alleged scope: 11 additional ex-Apple employees may have been involved as witnesses or participants. The filing includes specific allegations: one employee discussed Apple proprietary data with Liu and Yu-Ting Peng before Peng's OpenAI interview; another took screenshots of confidential documents before interviewing there. Apple also notes that after filing suit, multiple ex-employees working at OpenAI contacted the company about returning Apple-issued devices they'd retained. OpenAI denies possessing any Apple trade secrets and points to procedural errors in Apple's initial contact (emailing the wrong person). The practical question here: does the expanded witness list change the evidentiary weight, or is it still circumstantial without direct proof of what data actually moved?
