There is a six-month grace period after trademark expiration. If the extension is not renewed after the extension, the protection period will be one year according to the provisions of the Trademark Law. However, it is recommended to apply within the protection period, and rejected documents can be reviewed and resolved later. If you wait for the protection period to expire before processing the registration, you may be preempted by someone else's identical or similar trademark application. You will lose your right to use it
