Trademark validity period

The validity period of a registered trademark is 10 years, calculated from the date of approval of registration. You can renew and pay the renewal fee 12 months before the expiration of the validity period. Each renewal is still valid for 10 years, and there is no limit to the number of renewals. If the application is not submitted within this period, a 6-month extension period may be granted. If the renewal of registration is not submitted within the extension period, the Trademark Office will cancel the registered trademark and make an announcement.
