(3): An application for a patent may be made under subsection (1) or (2) by the legal representative of—
(a): a deceased person who, immediately before his death, was entitled to make such an application; or
(b): a person under disability who, had it not been for such disability, would himself have been entitled to make such application. 7 Form of application

(1): An application for a patent—
(a): which is not a Convention application, shall be accompanied by either a complete specification or a provisional specification;
(b): which is a Convention application, shall be accompanied by a complete specification.
(2): Subject to this section, where an application referred to in paragraph (a) of subsection (1) is accompanied by a provisional specification a complete specification shall be lodged within twelve months from the date that the application was lodged and if the complete specification is not so lodged the application shall be deemed to be abandoned: Provided that the complete specification may be lodged at any time after the expiration of the twelve months but within fifteen months from the date the application was lodged if a request to that effect is made to the Registrar and the prescribed fee is paid on or before the date on which the complete specification is lodged.
(3): Where two or more applications accompanied by provisional specifications have been lodged in respect of matters which are cognate or of which one is a modification of another, a single complete specification may, subject to this section and section nine, 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.
(5): In considering the validity of applications made in terms of subsection (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 subsection (4) of section seven shall, in the case of any such application, apply separately to the applications for protection in respect of each of the said matters.
(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 expiration of the period specified in subsection (2) and 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 subsection (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. 9 Contents of specification
(b): commence with a title clearly indicating the subject to which the relevant invention relates.
(c): contain an abstract of not more than two hundred words and drawings, if any. [inserted by Act 9 of 2002, with effect from the 20th December, 2002.]

(c): end with a claim or claims defining the subject-matter for which protection is claimed.
(5): A specification may, and if so required by the Registrar shall, be accompanied by drawings and such drawings shall be deemed to be part of the specification: Provided that 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.
(7): Where a complete specification claims a new substance, the claims shall be construed as not extending to that substance when found in nature. 10 Effective date of claims of complete specification
(1): A claim of a complete specification shall have effect from the date provided in 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 a 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 subsection (6) of section eight 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 specifications as are mentioned in subsection (2), and the claim is fairly based on the matter disclosed in one of those specifications, the effective date of that claim shall be the effective date of the application accompanied by that specification.
(4): Where the complete specification is lodged in pursuance of a Convention application, and the claim is fairly based on the matter disclosed in the application for protection in a Convention country or, if the Convention application is founded upon more than one such application for protection, in one of those applications, the effective date of that claim shall be the effective date of the relevant application for protection.
(5): Where, under subsections (1) to (4), any claim of a complete specification would, but for this subsection, have two or more effective dates, the effective date of that claim shall be the earlier or earliest of those dates.
(6): In any case to which subsection (2), (3), (4) or (5) does not apply, the effective date of a claim shall be the date of lodging of the complete specification in Zimbabwe. 11 Examination of applications and specifications
(1): An application for a patent, including any specification and other document accompanying such application or subsequently lodged within such time as may be prescribed at the Patent Office in pursuance of such application, shall be examined by an examiner for the purpose of ascertaining—
(a): whether the application, specification and accompanying documents comply with the requirements of this Act, including whether any of the grounds of opposition specified in subsection (1) of section seventeen are applicable; and
(b): in the case of a complete specification lodged after a provisional specification or of a Convention application, whether the matter claimed is substantially the same as that disclosed in the provisional specification or in the application lodged in the Convention country, as the case may be.
(2): An examination or investigation required by this Act shall not be deemed to warrant the validity of any patent and no liability shall be incurred by the State, the Minister, the Registrar or any examiner or other officer of the Patent Office by reason of or in connection with any such examination or investigation or report or other proceeding consequent thereon. 12 Ante-dating and post-dating of applications and specifications
(i): no application shall be post-dated under this subsection to a date later than six months from the date on which it was actually lodged or would, but for this subsection, be deemed to have been so lodged;
(ii): a Convention application shall not be post-dated under this subsection to a date later than the last date on which, under this Act, the application could have been made.
(2): Where an application or specification lodged under this Act is amended before
acceptance of the complete specification, the Registrar may direct that the application
or specification shall be post-dated to the date on which it is amended or, if it has
been returned to the applicant, to the date on which it is again lodged under this Act.
(3): Where, at any time after an application or specification has been lodged at the
Patent Office and before acceptance of the complete specification, a fresh application
or specification is lodged in respect of any part of the subject-matter of the first-
mentioned application or specification, the Registrar may direct that the fresh
application or specification shall be ante-dated to a date not earlier than the date of
lodging of the first-mentioned application or specification.
(4): An appeal shall lie from any decision of the Registrar under subsection (2) or (3).
13 Refusal of application in certain cases
(1): Subject to subsection (2), if it appears to the Registrar in the case of any
application for a patent that—
[amended by Act 9 of 2002, with effect from the 20th December, 2002.]
(a): it is frivolous on the ground that it claims as an invention anything obviously contrary to well-established natural laws; or

(b) the patent applied for cannot be granted by virtue of section two A; or

(b1) the use of the invention in respect of which the application is made would be generally expected—

(i): to endanger public order or public safety; or
(ii): to encourage offensive, immoral or anti-social behaviour; or

(iii) to endanger human, animal or plant life or health; or

(iv): to promote serious prejudice to the environment; or [inserted by Act 9 of 2002, with effect from the 20th December, 2002.]
(c): it claims as an invention a substance capable of being used as food or medicine which is a mixture of known ingredients possessing only the aggregate of the known properties of the ingredients or that it claims as an invention a process producing such a substance by mere admixture; he may refuse the application.

(3): An appeal shall lie from any decision of the Registrar under subsection (1) or (2). 14 Powers of Registrar if specification or application defective
(1): If, in the case of a complete specification lodged in pursuance of an application for a patent, which application was accompanied by a provisional specification, the result of any examination made in terms of subsection (1) of section eleven is adverse to the applicant in regard to any matter referred to in that subsection or it is found that the invention described in the complete specification includes matter not included in the provisional specification, the Registrar may, subject to subsection (6) of section nine—
(a): refuse to accept the complete specification until it has been amended to his satisfaction; or
(b): with the consent of the applicant, cancel the provisional specification and direct that the application be post-dated to the date upon which the complete specification was lodged at the Patent Office; or
(c): where the complete specification includes matter not included in the provisional specification—
(i): allow the application to be proceeded with in so far as the matter included both in the provisional and in the complete specification is concerned; and
(ii): allow an application for the additional matter included in the complete specification to be made and authorize the application for such additional matter, if lodged at the Patent Office within such period as he may determine, to be dated with the date on which the complete specification was lodged at the Patent Office.
(2): If in the case of a Convention application it is found that the matter claimed is not substantially the same as that claimed in the application made in the Convention country in question, the Registrar may, subject to subsection (6) of section nine—
(a): refuse to accept the application until it has been amended to his satisfaction; or
(b): with the consent of the applicant, treat the application as an application which is not a Convention application.
(3): If in the case of a Convention application it is found that the specification lodged in Zimbabwe includes matter not included in the specification lodged in the Convention country, the Registrar may—
(a): allow the application to be proceeded with in so far as the matter included in both the Convention country and the Zimbabwe specifications is concerned; and
(b): allow an application for the additional matter to be made and authorize such application, if lodged at the Patent Office within such period as he may determine, to be dated with the date on which the Zimbabwe specification was lodged at the Patent Office.
(4): An appeal shall lie from any decision of the Registrar under subsection (1), (2) or (3). 15 Lapsing of applications
(1): If a complete specification is not accepted within eighteen months from the date of lodging of the complete specification, the application to which that specification relates shall lapse unless—
(a): an appeal has been lodged in respect of the application and has not been determined or abandoned; or
(b): the time within which an appeal in respect of the application may be lodged has not expired; or
(c): the delay in accepting the specification was not due to any neglect or default on the part of the applicant: Provided that if, within twenty-one months from the date of the lodging of the complete specification, the applicant, by notice accompanied by the prescribed fee, so requires, the said period of eighteen months shall be extended to such period, not exceeding twenty-one months from the date of the lodging of the complete specification, as may be specified in that notice.
(2): If, at the expiration of the period allowed under subsection (1), an appeal to the Tribunal is pending under any of this Act in respect of the application or, in the case of an application for a patent of addition, either in respect of that application or in respect of the application for the patent for the main invention, or the time within which such an appeal could be brought in accordance with Part X, apart from any future extension of time thereunder, has expired, then—
(a): where such an appeal is pending or is brought within the time aforesaid or before the expiration of any extension of that time granted, in the case of the first extension, on an application made within that time or, in the case of a subsequent extension, on an application made before the expiration of the last previous extension, the said period shall be extended until such date as the Tribunal may determine;

(b) where no such appeal is pending or is so brought, the said period shall continue until the end of the time aforesaid or, if any extension of that time is granted as aforesaid, until the expiration of the extension or the last extension so granted. 16 Acceptance and publication of complete specification and cancellation thereof

(1): Subject to section fifteen, the complete specification may be accepted by the Registrar at any time after the applicant has complied with the requirements imposed upon him by this Act: Provided that the applicant may give notice to the Registrar requesting him to postpone acceptance until such date, not being later than eighteen months from the date of lodging of the complete specification, as may be specified in the notice and the Registrar may postpone acceptance accordingly.
(2): Subject to subsection (5), on the acceptance of a complete specification the Registrar shall give notice to the applicant who shall, within the prescribed period or within such further period as the Registrar may allow, advertise in the Journal the fact that the specification has been accepted and, unless the acceptance of the specification is so advertised, the application shall lapse.
(3): Upon advertisement in terms of subsection (2) the application form, the specification and the other documents essential to obtain acceptance which were lodged in pursuance thereof shall be open to public inspection unless the acceptance of the complete specification has been cancelled in terms of subsection (5) before such advertisement.
(4): After the date of the publication in terms of subsection (2) of notice of acceptance of a complete specification and until the sealing of a patent in respect thereof, the applicant shall have the like privileges and rights as if a patent for the invention had been sealed on the date of the publication of the notice unless the acceptance of the complete specification has been cancelled in terms of subsection (5) before that date.
(b): if the advertisement of the acceptance is subsequently published in the Journal, cause notice of the cancellation of the acceptance of the specification to be published in the Journal.
(6): The cancellation of the acceptance of a complete specification in terms of subsection (5) shall not preclude the Registrar from re-accepting that complete specification at a later date if at the time the applicant requested the cancellation he also gave notice to the Registrar such as is referred to in the proviso to subsection (1). 17 Opposition to grant of patent
(1): Any person interested, including the State, may within three months from the date of the advertisement of the acceptance of a complete specification which has not been cancelled in terms of subsection (5) of section sixteen or within such further period as the Registrar, on application made to him within the said period of three months, may allow, or, with the consent of the applicant, at any time before the sealing of the patent, oppose the grant of a patent in accordance with this section by giving written notice to the registrar of the Tribunal of opposition to such grant on any of the following grounds and no others—
(a): that the applicant is not a person entitled under section six to make the application;
(b): that the application is in fraud of the rights of the person giving such notice or of any persons under or through whom he claims;
(c): that the invention does not relate to an art, whether producing a physical effect or not, process, machine, manufacture or composition of matter which is capable of being applied in trade or industry;
(e): that the invention, in so far as is claimed in any claim of the complete specification, is not useful;

( f ) that the complete specification does not fully describe and ascertain the invention and the manner in which it is to be performed;

(i): that the application form or any other document filed in pursuance of the application contains a material misrepresentation;

( j) that the matter described or claimed in the complete specification is not the same as that described in the provisional specification, and—

(i): in so far as it is not described in the provisional specification, was not new at the date when the complete specification was lodged at the Patent Office; or
(ii): forms the subject of a pending application made in Zimbabwe for a patent the effective date of which is prior to the date on which the complete specification was lodged at the Patent Office;
(k): in the case of a Convention application, that the specification describes or claims matter other than that for which protection has been applied for in the Convention country and that such other matter either—
(m): that the specification includes claims which, in terms of subsection (1) of section thirteen, should have been refused.
(2): Any notice of opposition given under subsection (1) shall—

Provided that, for the purpose of determining whether there has been any abuse of the monopoly rights under a patent, due regard shall be had to the fact that patents are granted not only to encourage invention but also to secure that inventions shall so far as possible be worked on a commercial scale in Zimbabwe without undue delay. (6a) In the event of a practice determined after judicial or administrative process to be anti-competitive, the requirements contained in subsection (1) that the interested person shows that he has been unable to obtain a licence shall not apply.

(7): The Tribunal may order the grant to the applicant of a licence on such terms as it may think expedient, including a term precluding the licensee from importing into Zimbabwe any goods the importation whereof, by persons other than the patentee or persons claiming under him, would be an infringement of the patent.
(8): The terms of a licence ordered to be granted under subsection (7) shall be so framed as—
(a): to authorise the making, use or vend of the invention primarily to satisfy the market in Zimbabwe, except in the case of a determination of anti-competitive practices, in which case no such restriction shall apply; and

patent in question and shall in all other respects have the same rights as any other
licensee, and if the patentee fails, within two months after being called upon by the
licensee or within such further period as the Tribunal may allow, to institute any such
proceedings, the licensee may himself institute such proceedings as if he were the
patentee, making the patentee a defendant, but the patentee shall not be liable for any
costs in connection with such proceedings unless he enters an appearance and takes
part in those proceedings.
(14): The existence of a compulsory licence granted solely on the ground that an
invention is not being worked in Zimbabwe on a commercial scale shall not preclude
the grant of further licences, including compulsory licences, in respect of that
invention, but the holder of any compulsory licence shall not be entitled to transfer
that licence or grant a sub-licence thereunder except to a person to whom the business
or the part of the business in connection with which the rights under the licence were
exercised, has been transferred.
(15): No licence shall be granted in terms of this section or of section thirty-two while
