The China Trademark Network always cannot be opened. This is mainly because the website server is not maintained regularly, and the query volume is relatively large, so the Trademark Network often cannot be opened.

"China Trademark Network" is the only website hosted by the Trademark Office of the State Intellectual Property Office for online query of trademark registration information. The website provides three types of trademark registration information inquiries: identical or similar trademark information inquiries, trademark comprehensive information inquiries and trademark review status information inquiries.

Trademark identical or similar information query refers to querying whether there are identical or similar registered or previously applied trademarks on the same or similar goods; trademark comprehensive information query refers to the known trademark registration number ( or application number), applicant (or registrant) or trademark text; querying trademark review status information means that the applicant queries the status of the relevant trademark in the business process through the trademark application number or registration number.
