OpenAI fires back at Apple’s trade secret lawsuit with chat logs showing Apple employees kept texting their…

What happened

OpenAI responded to Apple’s trade secret lawsuit by releasing iMessage conversations involving former Apple engineer Chang Liu. The chats reveal that Apple employees continued to reach out to Liu after he left the company, requesting technical information and internal files. This challenges Apple’s claim that Liu misappropriated trade secrets without company authorization.

Why it matters

Apple’s case depends on proving that Liu acted alone and improperly accessed confidential information. These chat logs suggest Apple employees were actively involved in contacting their ex-colleague, showing a blurred line in control over sensitive information. This could weaken Apple’s legal position and shift some responsibility back onto the company itself. For operators and investors, it highlights the challenge of policing talent movement and internal knowledge flow in highly competitive AI and tech sectors.

What to watch next

The courts will need to decide whether Apple’s internal practices contributed to the alleged trade secret leak. Watch for how both companies adjust their messaging and legal strategies as the back-and-forth over information access unfolds. For AI builders and business leaders, the case underscores the importance of rigorous security protocols and clear post-employment policies on knowledge and data handling.
