If the change certificate is not submitted, it can be corrected within 30 days from the date of filing the application. If it is not submitted at the expiration of the time limit, it shall be deemed as giving up the application for change, and the Trademark Office shall notify the applicant in writing.
Where the name or address of a trademark registrant is changed, the trademark registrant shall change all its registered trademarks together; If it is not changed at the same time, it shall be deemed as a waiver of the application for change, and the Trademark Office shall notify the applicant in writing.
