Apple claims an ex-employee stole Apple Watch trade secrets for Oppo

Here is a 193-word summary of the news article: Apple is suing a former employee, Chen Shi, who worked on the Apple Watch team, for allegedly stealing trade secrets and sharing them with his new employer, Chinese tech company Oppo. According to the lawsuit, Shi did not disclose that he was leaving Apple to join Oppo, and instead claimed he was returning to China to care for his elderly parents. However, Apple claims Shi secretly met with Apple Watch team members to learn about their work on sensors and other technologies. The lawsuit alleges Shi downloaded 63 files from a protected Apple folder and searched the internet for ways to cover his tracks. Apple also claims Shi told Oppo he would "collect as much information as possible" about Apple's health-sensing technologies. Oppo has denied any wrongdoing, stating it has found no evidence linking the allegations to the employee's conduct during his time at the company. This is not the first time Apple has sued a former employee over trade secret theft - earlier this year, the company took legal action against a design engineer who allegedly shared Vision Pro secrets with Snap. Apple appears determined to protect its proprietary technologies, even as employees move to competitors.
