It states that Liu used a company-issued laptop after his departure to access engineering presentations, technical specifications, and project data, and coached a colleague on bypassing security protocols while copying files. The filing further alleges that Tan directed job candidates to bring physical parts for “show and tell” sessions about unannounced products and instructed new hires not to disclose their OpenAI roles to Apple so they could remain longer at the company.
Apple and OpenAI formed a partnership in 2024 to integrate ChatGPT into Apple devices.
Apple seeks a preliminary and permanent injunction requiring the return of confidential information along with unspecified damages. The suit follows internal concerns Apple raised before filing, with discovery expected to examine whether evidence was concealed or destroyed.
” TechCrunch reported that Apple alleges the misconduct was directed by OpenAI's senior leadership, including a longtime former employee.
