(2) Every such application shall contain a statement of the circumstances which have led to the omission of the payment of the prescribed fee.
(3) If it appears from such statement that the omission was unintentional and that no undue delay has occurred in the making of the application, the Registrar shall advertise the application in the prescribed manner, and within such time as may be prescribed any person may give notice of opposition at the Registry of Patents.
(4) Where such notice is given the Registrar shall notify the applicant.
(5) After the expiration of the prescribed period the Registrar shall hear the case and, subject to an appeal to the Court, issue an order either restoring the patent or dismissing the application: Provided that in every order under this article restoring a patent such provisions as may be prescribed shall be inserted for the protection of persons who may have availed themselves of the subject-matter of the patent after the patent had been announced as void in the Gazette.
