If the applicant fails to go through the registration formalities within the prescribed time limit, it shall be deemed as giving up the right to obtain the patent right. If the applicant has justified reasons to delay the deadline, he can request the restoration of his rights. The request to restore the right shall be filed within 2 months from the date when the Patent Office issues the notice of giving up the patent right, and at the same time, the registration formalities shall be completed (the patent registration fee and the annual fee for authorization shall be paid, and the maintenance fee shall also be paid if the application for a patent for invention is required) and the fees required for restoring the right shall be paid.
