The document summarizes a presentation by Michael Lin on patent enforcement in China. It discusses that China has a civil law system with non-binding precedents and inconsistent court rulings. It outlines that the patent office and customs office can administratively enforce patents through investigations, seizures and fines. However, customs enforcement depends on the information provided and often requires following up in court. It also notes issues with arbitration in China through CIETAC, recommending designating cases in Beijing for now.
