Legal analysis: The validity period of a registered trademark is ten years, calculated from the date of approval of registration. If a registered trademark expires and needs to be continued to be used, the trademark registrant shall go through the renewal procedures in accordance with the regulations within twelve months before expiration; if it fails to do so during this period, a six-month extension period may be granted. Each renewal of registration is valid for ten years, starting from the day after the expiration of the previous term of validity of the trademark. If renewal procedures are not completed upon expiration, the registered trademark will be cancelled. The Trademark Office shall announce the renewal of registered trademarks. It is known from the above that the validity period of a trademark is 10 years, and the trademark holder can renew it indefinitely.
