a registered trademark is valid for 1 years. Where it is necessary to continue to use a registered trademark after its expiration, it shall apply for renewal of registration within 6 months before its expiration. If an application cannot be submitted during this period, there will be a six-month grace period. If no application is filed within the grace period, the Trademark Office will cancel it after the expiration. (The new Trademark Law was implemented on May 1, 214, and a registered trademark can be renewed 12 months before its expiration.)
