(7) A patent granted in Zambia for an invention upon an application made in terms of this section shall not be invalidated by reason only of—

(ii) an application for a patent has been made by any other person, or a patent has been granted on such an application;

(3) The powers of the Minister under this section, so far as they are exercisable for the benefit of persons from whom inventions have been communicated to the Government by the government of any country, shall only be exercised if and to the extent that the Minister is satisfied that substantially equivalent provision has been or will be made under the law of that country for the benefit of persons whose inventions have been communicated by the Government to the government of that country.
(4) References in sub-section (3) to the communication of an invention to or by the Government or the government of any country shall be construed as including references to the communication of the invention by or to any person authorised in that behalf by the government in question.

[S 12 am by GN 185 of 1964.]
(1) Every application for a patent, other than a convention application, shall be accompanied by either a complete specification or a provisional specification and every convention application shall be accompanied by a complete specification.
(2) If a complete specification does not accompany an application, it shall be lodged within 12 months after the date of lodging of the application or within such further period, not exceeding three months, as the Registrar may in writing allow upon payment of the prescribed fee, and if the provisions of this sub-section are not complied with the application shall lapse.
(3) Where two or more applications accompanied by provisional specifications have been lodged in respect of inventions which are cognate or of which one is a modification of another, a single complete specification may, subject to the provisions of this section and section 14, be lodged in pursuance of those applications, or, if more than one complete specification has been lodged, may with the leave of the Registrar be proceeded with in respect of those applications.
(4) Where applications for protection have been made in one or more convention countries in respect of two or more inventions which are cognate or of which one is a modification of another, a single convention application may, subject to the provisions of sections 11 and 14, be made in respect of those inventions at any time within 12 months from the effective date of the earliest of the said applications for protection.
(5) In considering the validity of applications made in terms of sub-section (3) or (4) and in determining other relevant matters under this Act, the Registrar shall have regard to the effective dates of the applications or the convention applications concerned relating to the several matters claimed in the specification, and the requirements of sub-section (4) of section 12 shall, in the case of any such application, apply separately to the applications for protection in respect of each of the said inventions.
(6) Where an application for a patent, not being a convention application, is accompanied by a specification purporting to be a complete specification, the Registrar may, if the applicant so requests at any time before the acceptance of the specification, direct that it shall be treated for the purposes of this Act as a provisional specification and proceed with the application accordingly.
(7) Where a complete specification has been lodged in pursuance of an application for a patent accompanied by a provisional specification or by a specification treated by virtue of a direction under sub-section (6) as a provisional specification, the Registrar may, if the applicant so requests at any time before the acceptance of the complete specification, cancel the provisional specification and post-date the application to the date of lodging of the complete specification.
(1) Every specification shall indicate whether it is a provisional or a complete specification and shall commence with a title sufficiently indicating the subject to which the relevant invention relates.
(2) A provisional specification shall fairly describe the invention.
(3) A complete specification shall—
(a) fully describe the invention and the manner in which it is to be performed;
(b) disclose the best method of performing the invention known to the applicant at the time when the specification is lodged at the Agency; and

(4) The claim or claims of a complete specification must relate to a single invention, must be clear and succinct, and must be fairly based on the matter disclosed in the specification.
(5) Every specification shall be accompanied by drawings if required by the Registrar, and such drawings shall be deemed to be part of the specification, but if drawings which accompanied a provisional specification are sufficient for the purpose of a complete specification, it shall suffice if that complete specification refers to such drawings.
(6) Subject to the foregoing provisions of this section, a complete specification lodged at the Agency after a provisional specification, or with a convention application, may include claims in respect of developments of or additions to the invention which was described in the provisional specification or, as the case may be, in respect of which application for protection was made in a convention country, being developments of or additions in respect of which the applicant would be entitled to make a separate application for a patent:
Provided that an application shall, in so far as the complete specification contains claims in respect of any such developments or additions, be deemed to have been made on the date on which the complete specification was lodged at the Agency.
(7) Where a complete specification claims a new substance, the claim shall be construed as not extending to that substance when found in nature.
(1) Every claim of a complete specification shall have effect from the date prescribed by this section in relation to that claim and a patent shall not be invalidated by reason only of the publication or use of the invention, so far as claimed in any claim of the complete specification, on or after the effective date of that claim, or by the grant of another patent upon a specification claiming the same invention in a claim of the same or later effective date.
(2) Where the complete specification is lodged in pursuance of a single application preceded by a provisional specification or by a specification which is treated by virtue of a direction under sub-section (6) of section 13 as a provisional specification, and the claim is fairly based on the matter disclosed in that specification, the effective date of that claim shall be the effective date of the application.
(3) Where the complete specification is lodged or proceeded with in pursuance of two or more applications accompanied by such
