Of course, paragraph 1 of Article 38 of the Trademark Law stipulates: "If a registered trademark needs to continue to be used after its expiration, it shall apply for renewal of registration within 12 months before its expiration; Failing to apply within this time limit, a grace period of 6 months may be granted. If no application is made at the expiration of the extension period, its registered trademark will be cancelled. " This paragraph stipulates the application period and extension period for renewal of registration. Each application shall submit an application for trademark renewal registration, five copies of the trademark pattern of the registered trademark and a copy of the trademark registration certificate (the original trademark registration certificate is not required) to the Trademark Office, and pay the renewal registration fee. If the registrant applies for renewal within the grace period, it shall pay the renewal fee in accordance with the regulations.
