This facility means that China does not recognize unregistered trademark rights. So you must register your trademark to have any trademark protection. Without trademark protection, someone else can register “your” trademark and then prevent you from using it. The person who registers for the trademark in China will get the right to distribute and sell the products. Effective and beneficial at the same time. Your Chinese trademark, just like your U.S. trademark, will not expire as long as the goods and services.
