In order to safeguard the rights of the holder of an application or the holder of a patent registration certificate, payment of the renewal fee to the Registration Authority commences after two years have elapsed from the date of filing of the application, and thereafter continues annually or periodically, within the window of two months before the expiry of its validity. Delay in payment of this fee is permitted for at most six months, subject to payment of a penalty equal to twice the renewal fee; otherwise, the application shall be deemed withdrawn or the patent certificate shall become invalid, and the Registration Authority is obliged to publish the invalidity of the patent certificate within forty-five days.

Note 1 — The amount of the annual or periodic installments for inventions shall be determined in the executive regulations of this Act, and the future installments of inventions registered before the adoption of this Act and its executive regulations shall be calculated in accordance with the new tariffs.

Note 2 — The holder of an application or patent registration certificate may pay the fee for a five-year period in one payment.

Note 3 — Where early publication takes place pursuant to Article (27) of this Act and, for other reasons, registration of the invention is effected before two years from the date of filing of the application, the initial registration fee must be paid in a single payment and ahead of schedule.

Note 4 — The Registration Authority is obliged, one month before the due date for payment of the annual installments stated in this Article, to inform the holder of the patent registration certificate, in an appropriate manner, of the necessity of paying the renewal fee.
