The filing also addressed the conduct of the two former Apple employees named in the lawsuit. According to Chang Liu, any post-departure access to Apple documents was carried out to assist former colleagues in finding files or responding to questions about Apple work, and he said Apple employees had reached out to him for help after he had already left the company. Tang Tan, a 24-year Apple veteran who now leads hardware at OpenAI, stated in the filing that he gave back all Apple prototypes prior to his exit and kept nothing that qualified as confidential, pointing to an employee departure checklist as an example of what he held onto.
