A: China Trademark Network is updating its new system, so the website has been unable to open recently and will not open at ordinary times, but it is not as serious as it is now. Just get used to it. The main reason is that the website server can't work, and it can't be opened when the query volume is large, which has something to do with your network bandwidth. Then the trademark network will update the content regularly, and it can't get on at this time. Try the trademark inquiry network. Trademark. com
