The validity period of a registered trademark is usually 10 years, calculated from the date of approval of registration.

If the trademark registrant wants to continue to use the trademark, he should go through the renewal procedures within 12 months before the expiration date. The validity period of each renewal is also 10 years, starting from the day after the last validity period expires. If the trademark owner fails to complete the renewal procedures in time, there is still a 6-month extension period, that is, it can be renewed for up to 6 months after the trademark expires. If the renewal is not completed within the grace period, the registered trademark will be cancelled.

1. The principle of good faith must be followed;

2. Legal elements must be present;

3. The trademark must have distinctive features, be easy to identify, and must not conflict with the legal rights previously obtained by others;

Trademark registrants can apply for renewal within 12 months before the expiration of the validity period, or apply for renewal procedures during the subsequent 6-month extension period to maintain their trademark rights.
