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 example of Apple publicly going after a former employee for leaking internal information

Apple is an intensely secretive company, and lawsuits 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. "Worse still, the review of Mr

Liu's Apple-issued work laptop also shows that while maintaining access to Apple's prietary Information under false pretenses, he used his Apple credentials to exfiltrate thousands of documents containing prietary Information from Apple's secure file storage systems," the iPhone maker's lawyers said in the filing

Many of the files downloaded by Liu had codenames for Apple jects and described the company's nology, duct 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

Liu worked on Apple's Vision headset as a system duct design engineer, per the filing

Apple is not suing Snap, and the social media company did not respond to a request for. "The overlap between Apple's prietary Information that Mr

Liu retained and Snap's AR ducts (for which Mr

Liu is a 'duct design engineer') suggests that Mr

Liu intends to use Apple's prietary Information at Snap," according to the filing

Apple is seeking damages and for Liu to have his devices inspected by a forensic examiner to make sure all the trade secrets are deleted

The iPhone maker has sued several former employees in recent years for taking files when they left the company

That lawsuit was dismissed after Aude apologized

Additionally at least three former Apple employees have also been arrested and accused by the government of taking company secrets and giving them to China-linked organizations

One pled guilty and was sentenced to four months in prison, and two are still in ceedings
