1. "Madrid International Trademark Registration" is only a simple "way" for applicants to register international trademarks. In the end, whether a trademark is protected by a member country must be handled in accordance with the procedures of that country.

2. A trademark whose territory extends to China and is registered is essentially the same as a trademark where the applicant applies directly to China and is approved for registration. Naturally, it must abide by the provisions of China's Trademark Law.

3. According to Article 44 of the Trademark Law, if a registered trademark is used and any of the following acts are committed, the Trademark Office shall order it to correct or cancel the registered trademark within a time limit:

( 1) Changing the registered trademark on one's own initiative;

(2) Changing the name, address or other registration information of the registered trademark on one's own initiative;

(3) Transferring the registered trademark on one's own initiative;

(4) Stopped from use for three consecutive years.

4. Therefore, if you think that the trademark has not been used for three consecutive years, you can apply to the Trademark Office to cancel the registered trademark.
