Status:

This is the original version (as it was originally enacted).

18Substantive examination and grant or refusal of patent

(1)Where the conditions imposed by section 17(1) above for the comptroller to refer an application to an examiner for a preliminary examination and search are satisfied and at the time of the request under that subsection or within the prescribed period—

(a)a request is made by the applicant to the Patent Office in the prescribed form for a substantive examination; and

(b)the prescribed fee is paid for the examination;

the comptroller shall refer the application to an examiner for a substantive examination; and if no such request is made or the prescribed fee is not paid within that period, the application shall be treated as having been withdrawn at the end of that period.

(2)On a substantive examination of an application the examiner shall investigate, to such extent as he considers necessary in view of any examination and search carried out under section 17 above, whether the application complies with the requirements of this Act and the rules and shall determine that question and report his determination to the comptroller.

(3)If the examiner reports that any of those requirements are not complied with, the comptroller shall give the applicant an opportunity within a specified period to make observations on the report and to amend the application so as to comply with those requirements (subject, however, to section 76 below), and if the applicant fails to satisfy the comptroller that those requirements are complied with, or to amend the application so as to comply with them, the comptroller may refuse the application.

(4)If the examiner reports that the application, whether as originally filed or as amended in pursuance of section 17 above, this section or section 19 below, complies with those requirements at any time before the end of the prescribed period, the comptroller shall notify the applicant of that fact and, subject to subsection (5) and sections 19 and 22 below and on payment within the prescribed period of any fee prescribed for the grant, grant him a patent.

(5)Where two or more applications for a patent for the same invention having the same priority date are filed by the same applicant or his successor in title, the comptroller may on that ground refuse to grant a patent in pursuance of more than one of the applications.
