In the event that this period is missed, the renewal request may be made within a six-month extension from the last day of the month in which the protection period ends, provided that an additional fee is paid. The renewal period starts on the day the current registration ends. The renewal is registered and published. Trademarks which are not renewed within six months after the end of the protection period shall be deemed null and void.
