Overview

• Apple filed the case in the Northern District of California, accusing former employee Chen Shi and Oppo of misappropriating Apple Watch confidential information.
• Apple alleges Shi, a Sensor System Architect until June 2025, downloaded 63 files from a protected Box folder, copied them to a USB drive, and searched how to wipe a MacBook and avoid shared-drive detection.
• The complaint says the materials included proprietary health‑sensing methods for PPG, ECG, and temperature features, plus chip engineering documents and product roadmaps.
• Exhibits quote Shi telling Oppo he was “collecting as much information as possible,” with Oppo health executive Zi Zijing Zeng replying “alright” and an OK emoji, which Apple cites to name Oppo as a defendant.
• Apple seeks injunctions and monetary damages, while Oppo denies any misappropriation and says it will cooperate with the legal process.
