Apple has filed a lawsuit against OpenAI alleging trade secret theft, claiming the AI company poached over 400 employees from Apple. According to a new court filing, evidence discovered on former Apple employee Chang Liu's work MacBook suggests OpenAI is actively destroying evidence. The filing claims Liu secretly downloaded confidential Apple circuit schematics and coordinated with colleagues to destroy data after learning of Apple's investigation.

Apple urges expedited discovery, warning that delays cause increasing harm and risk further evidence loss. OpenAI denies wrongdoing, arguing Apple's lawsuit is a competitive tactic. The case highlights ongoing tensions between tech giants in the AI space, with Apple asserting that Liu's laptop contains critical evidence of systematic data theft that defendants have allegedly ignored.

Legal experts note this follows a July lawsuit naming two former Apple executives accused of IP theft.
