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

If the registered trademark expires and needs to be continued to be used, the registrant should apply for renewal of registration within 6 months before expiration.

If the registrant fails to apply for renewal during this period, it can apply within the 6-month extension period after the expiration, but a renewal registration delay fee will be required.

If no renewal application is submitted after the extension period expires, the Trademark Office will cancel the registered trademark; if the registrant wants to continue to use the registered trademark, he must resubmit a registration application.
