What key R&D staff take away when they leave is often not "complete drawings / complete code / complete formula," but key parameters, structural coupling relationships, process windows, test data, BOM component-selection logic, digital model drawings, algorithm details and other "parts of the technical solution." Individually, these fragments look unremarkable — but once the new employer pieces them together, they can significantly shorten the R&D cycle, bypass trial-and-error costs, and even go straight into mass production. This is exactly the high-frequency scenario in technical-secret disputes. In the second-instance (appeal) proceedings of the Geely v. WM Motor technical-secret infringement case , the Intellectual Property Court of the Supreme People's Court expressly held that the defendants had not only obtained technical secrets by improper means, but had also "illegally disclosed part of the technical secrets by filing patent applications" and used the technical secrets to manufacture and sell products — conduct constituting infringement. The court ultimately awarded damages of approximately RMB 640,000,000, and applied double punitive damages for part of the period. The signal sent by such second-instance rulings is unmistakable: technical secrets can be protected, can attract high damages awards, and can drive the cost of infringement to the point where it is "not worth the gain." What follows is an actionable rights-enforcement roadmap, framed from the angle of what companies can actually "follow and do."
