The useful life of a trademark is only 10 years, for example: 2018.7.25~2028.7.24

If you need to continue to use a registered trademark after it expires, you should do so 6 months before expiration. Apply for renewal of registration within. If you fail to apply during this period, there is still a 6-month extension period. If an application has not been filed within the extension period, the Trademark Office will cancel it after the expiration of the extension period. After the Trademark Office examines the trademark renewal registration application, it 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.

How to apply for renewal of a registered trademark:

Entrust a nationally recognized trademark agency to handle it.

Applicants go directly to the Trademark Registration Hall of the Trademark Office to apply.
