On request, the registration of a mark may be indefinitely renewed for consecutive periods of ten years each, subject to payment by the owner of the prescribed renewal fee. A grace period of ten (10) months shall be granted for the payment of the renewal fee after the deadline, in return for payment of the prescribed surcharge.
