Hello, after successfully obtaining the trademark registration certificate, you need to pay attention to the following issues:

1. When using a trademark, it is necessary to abide by the trademark use regulations stipulated by the state, otherwise it will easily lead to the revocation of the trademark;

2. If the trademark has not been used for three consecutive years, then anyone can apply for cancellation of its trademark;

3. The trademark is valid for 10 year, and can be renewed 6 months before its expiration. After the expiration of the validity period, there will be a six-month extension, during which an additional extension fee will be charged. If it is not renewed within the time limit, the Trademark Office will revoke the overdue trademark;

4. Pay close attention to the use of trademarks in time, and beware of fraudulent use or infringement by others. If this happens, you should keep the evidence and apply to the judicial organs to safeguard your legitimate rights and interests.
