The validity period of a registered trademark is 10 years. If a registered trademark needs to be continued to be used after its validity period expires, it should apply for renewal of registration within 12 months before expiration; if the application fails to be made during this period, a six-month extension period can be given. If an application is not made within the extension period, the registered trademark will be cancelled. After reviewing the trademark renewal registration application, the Trademark Office will issue a trademark renewal certificate and will not issue another trademark registration certificate. The original trademark registration certificate and trademark renewal certificate will be used together. According to the Trademark Law revised in 2013, Article 40 If a registered trademark expires and needs to be continued to be used, the trademark registrant shall handle 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 grace 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.
