Apple Sues Former Vision Pro Employee for Stealing Secrets

Apple (NASDAQ:AAPL) has accused a former engineer for its Vision Pro headset computer of stealing company trade secrets before starting a new job at Snap (NYSE:SNAP), according to a lawsuit filed in California last week.

In the June 24 court filing, Apple accuses Di Liu, a senior design engineer, of downloading thousands of documents in his final days at the Cupertino company last year and saving them to his personal cloud accounts.

This lawsuit is the latest example of Apple publicly going after a former employee for leaking internal information. Apple is an intensely secretive company, and lawsuits like this one highlight how the iPhone maker exercises tight control over its internal information, even if it has to pursue legal action against former staff.

Apple alleges that Liu didn’t inform the company when he resigned late last year that he was headed to Snap, a competitor and maker of smart glasses. As a result, Apple did not shut off his access to accounts and allowed him a customary two-week transition period, which he used to download company files, according to the lawsuit.

Many of the files downloaded by Liu had codenames for Apple projects and described the company’s technology, product design and supply chain, according to the lawsuit. Apple says that all employees agree to keep Apple files confidential and that Liu broke confidentiality agreements he made when he joined. Liu worked for Apple between 2017 and 2024, according to the lawsuit.

AAPL shares popped $5.07, or 2.4%, to $212.89, while those for SNAP eked up two cents to $9.37.
