Apple is suing OpenAI, alleging that the company encouraged prospective employees to study confidential Apple materials and bring hardware components to interviews. The lawsuit claims that former iPhone engineer Chang Liu left Apple with a company-issued MacBook and knowledge of a software bug that gave him access to internal file servers, which he used to download confidential information while working at OpenAI. According to the suit, Liu wrote to a former Apple colleague, "LOL, I found out I can access the [network storage], so funny," and then used that access to download presentations, hardware designs, manufacturing details and testing procedures. The colleague replied, "I'm ready," and helped obtain more information. OpenAI responded that it has "no interest in other companies' trade secrets" and remains focused on building innovative technology, while Apple alleges that OpenAI's hardware business relies on misappropriated trade secrets. The lawsuit was filed Friday.
