Legal analysis: The validity period of trademark registration is generally 10 years, and an application needs to be made one year before expiration. Failure to renew the trademark upon expiration will cause irreparable losses to the enterprise. Because after a trademark is successfully registered, its validity period is generally ten years. If it is not renewed after expiration, it will not be protected by law. The adverse consequences are as follows: 1. The intangible assets represented by the registered trademark will return to zero; 2. The brand influence gained by promoting and publicizing this trademark for many years will be easily taken away by others and no longer belongs to the owner; 3. If the trademark is used by others again Once registered, it can no longer be used; if no one else registers it, the trademark can no longer be used as a registered trademark, and the trademark needs to be re-registered.

Legal basis: Article 40 of the Trademark Law of the People's Republic of China. If a registered trademark expires and needs to be continued to be used, the trademark registrant shall comply with the regulations within twelve months before expiration. Go through the renewal procedures; if you fail to do so during this period, you can be given a six-month extension period. 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.
