(2)

Applications for patents

(2)Anything which consists of—

(a)a discovery;

(b)a scientific theory;

(c)a mathematical method;

(d)a literary, dramatic, musical or artistic work or any other aesthetic creation;

(e)a scheme, rule or method for performing a mental act, playing a game or doing business;

(3)The provisions of subsection (2) shall prevent, only to the extent to which a patent or an application for a patent relates to that thing as such, anything from being treated as an invention for the purposes of this Act.

(4)A patent shall not be granted—

(a)for an invention the publication or exploitation of which would be generally expected to encourage offensive or immoral behaviour; or

(b)for any variety of animal or plant or any essentially biological process for the production of animals or plants, not being a micro-biological process or the product of such a process.

(5)An invention shall be deemed to be new if it does not form part of the state of the art immediately before the priority date of any claim to that invention.

(6)The state of the art shall comprise all matter (whether a product, a process, information about either, or anything else) which has been made available to the public (whether in the Republic or elsewhere) by written or oral description, by use or in any other way.

(7)The state of the art shall also comprise matter contained in an application, open to public inspection, for a patent, notwithstanding that that application became open to public inspection on or after the priority date of any claim to that invention, if—

(a)that matter was contained in that application both as lodged and as open to public inspection; and

(b)the priority date of that matter is earlier than that of the relevant claim.

(8)An invention used secretly and on a commercial scale within the Republic shall also be deemed to form part of the state of the art for the purposes of subsection (5).

(10)Subject to the provisions of section 39 (6), an invention shall be deemed to involve an inventive step if it is not obvious to a person skilled in the art, having regard to any matter which forms, immediately before the priority date of any claim to the invention, part of the state of the art by virtue only of subsection (6) (and disregarding subsections (7) and (8)).

(11)An invention of a method of treatment of the human or animal body by surgery or therapy or of diagnosis practised on the human or animal body shall be deemed not to be capable of being used or applied in trade or industry or agriculture.

26. Prior knowledge or publication of invention excused in certain circumstances

A patent shall not be invalid by reason only of the fact that the invention in respect of which the patent was granted or any part thereof was disclosed, used or known prior to the priority date of a claim to the invention—

(a)if the patentee or his predecessor in title proves that such knowledge was acquired or such disclosure or use was made without his knowledge or consent, and that the knowledge acquired or the matter disclosed or used was derived or obtained from him, and, if he learnt of the disclosure, use or knowledge before the priority date of the claim in question, that he applied for and obtained protection for his invention with all reasonable diligence after learning of the disclosure, use or knowledge; or

(b)as a result of the invention being worked in the Republic by way of reasonable technical trial or experiment by the applicant or patentee or the predecessor in title of the applicant or patentee.

27. Who may apply for a patent

(1)An application for a patent in respect of an invention may be made by the inventor or by any other person acquiring from him the right to apply or by both such inventor and such other person.

(2)In the absence of an agreement to the contrary, joint inventors may apply for a patent in equal undivided shares.

28. Disputes as to rights in or to inventions or patents

(3)The licensee under a licence granted by virtue of the endorsement of a patent in terms of this section may (unless in the case of a licence whereof the conditions are decided by agreement, the licence otherwise expressly provides) call upon the patentee to institute proceedings in respect of any infringement of the patent, and if the patentee fails to do so within two months after being so called upon, the licensee may institute proceedings for the infringement in his own name as if he were patentee, joining the patentee as a defendant.

(4)A patentee so joined as a defendant shall not be liable for any costs unless he enters an appearance and takes part in the proceedings.

(5)An application for the endorsement of a patent in terms of this section shall contain a statement, to be verified in such manner as may be prescribed, that the patentee is not precluded by contract from granting licences under the patent, and the registrar may require from the applicant such further evidence as he may think necessary.

(6)An application under this section for the endorsement of a patent of addition shall be dealt with as an application for the endorsement of the patent for the main invention also, and an application made under this section for the endorsement of a patent in respect of which a patent of addition is in force, shall be dealt with as an application for the endorsement of the patent of addition also, and where a patent of addition is granted in respect of a patent already endorsed under this section, the patent of addition shall also be so endorsed.

(2)Where such an application is made and the balance paid of all renewal fees which would have been payable if the patent had not been endorsed, the registrar may, if he is satisfied that there is no existing licence under the patent or that all licensees under the patent consent to the cancellation, cancel the endorsement.

(3)Within the prescribed period after a patent has been endorsed in terms of section 53, any person who claims that the patentee is, and was at the time of the endorsement, precluded by a contract in which the claimant is interested from granting licences under the patent, may apply to the registrar for cancellation of the endorsement.

(4)Where the registrar is satisfied, on an application under subsection (3), that the patentee is and was precluded as aforesaid, he shall cancel the endorsement, and thereupon the patentee shall pay to the registrar, within such period as may be prescribed, a sum equal to the balance of all renewal fees which would have been payable if the patent had not been endorsed and, if that sum is not paid within that period, the patent shall lapse at the expiry of that period.

(5)An application for the cancellation of the endorsement of a patent of addition shall be dealt with as an application for the cancellation of the endorsement of the patent for the main invention also, and an application for the cancellation of the endorsement of a patent in respect of which a patent of addition is in force shall be dealt with as an application for the cancellation of the endorsement of the patent of addition also.

(6)Where the endorsement of a patent is cancelled under this section, the rights and liabilities of the patentee shall thereafter be the same as if the endorsement had not been made.

55. Compulsory licences in respect of dependent patents

Where the working of a patent (hereinafter referred to as a dependent patent) without infringement of a prior patent is dependent upon the obtaining of a licence under that prior patent, the proprietor of the dependent patent may, if agreement cannot be reached as to such licence with the proprietor of the prior patent, apply to the commissioner for a licence under the prior patent, and the commissioner may grant such a licence on such conditions as he may impose, but including a condition that such licence shall be used only for the purpose of permitting the dependent patent to be worked and for no other purpose.

(a)the patented invention is not being worked in the Republic on a commercial scale or to an adequate extent, after the expiry of a period of four years subsequent to the date of the application for the patent or three years subsequent to the date on which that patent was sealed, whichever period last expires, and there is in the opinion of the commissioner no satisfactory reason for such non-working;

(b)the working of the invention in the Republic on a commercial scale or to an adequate extent is being prevented or hindered by the importation of the patented article;

(c)the demand for the patented article in the Republic is not being met to an adequate extent and on reasonable terms;

(d)by reason of the refusal of the patentee to grant a licence or licences upon reasonable terms, the trade or industry or agriculture of the Republic or the trade of any person or class of persons trading in the Republic, or the establishment of any new trade or industry in the Republic, is being prejudiced, and it is in the public interest that a licence or licences should be granted; or

(e)the demand in the Republic for the patented article is being met by importation and the price charged by the patentee, his licensee or agent for the patented article is excessive in relation to the price charged therefor in countries where the patented article is manufactured by or under licence from the patentee or his predecessor or successor in title.

(3)The patentee or any other person appearing from the register to be interested in the patent may in the prescribed manner oppose the application.

(4)

(a)The commissioner may order the grant to the applicant of a licence on such conditions as he may deem fit, including a condition precluding the licensee from importing into the Republic any patented articles.

(b)If the commissioner is of the opinion that an order directing the grant of a licence is not justified, he may refuse the application.

(5)If the only abuse found by the commissioner to have been established is that set out in subsection (2)(a), any licence granted shall be non-exclusive but shall not be transferable 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.

(6)In all other cases the commissioner may grant an exclusive licence if, having regard to all the circumstances of the case, he considers it justified, and for that purpose he may revoke any existing licence on such conditions as he may deem fit.

(7)In determining the conditions on which any licence is granted the commissioner shall have regard to any relevant facts, including the risks to be undertaken by the licensee, the research and development undertaken by the patentee and the terms and conditions usually stipulated in licence agreements in respect of the subject-matter of the invention, between persons who voluntarily enter into such agreements.

(7A)The commissioner may order that a licence granted in terms of this section shall be deemed to have been granted on the date on which the application has been received by the registrar.[subsection (7A) inserted by section 2(b) of Act 76 of 1988]

(a)the patentee concerned shall be cited as a party to such proceedings;

(b)the patentee may join in the proceedings either as co-plaintiff or as co-defendant; and

(c)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.

(a)the exclusive licensee shall be cited as a party to such proceedings;

(b)the exclusive licensee may join in the proceedings either as co-plaintiff or as co-defendant; and

(b)In so awarding costs, the commissioner shall inter alia have regard to—

(i)the nature and extent of the abuse found by him to have been established; and

(ii)whether the application for a licence under this section might have been avoided by the grant, by the patentee concerned to the applicant, of a voluntary licence on reasonable terms.

(14)For the purposes of this section the expression "patented article" includes any composition of matter or any product of a patented process or method or any product produced by a patented machine.

57. Termination of contracts relating to licences

(2)Nothing in this section shall affect any right to terminate a contract or a condition in a contract independently of this section.

58. Effect of licence

In default of an agreement to the contrary—

(a)a licence to make a patented article shall carry with it the right to use or dispose of the patented article; and

63. After revocation on ground of fraud inventor may obtain patent in certain circumstances

Where a patent is revoked on the ground of fraud, or a patent fraudulently obtained has been surrendered and revoked, the commissioner may, on the application of the inventor of the relevant invention or his assignee or legal representative, made accordance with the provisions of this Act, direct the grant to him of a patent for the whole or any part of the invention, bearing the same date as the patent so revoked.

(6)Damages contemplated in subsection (3)(c) may be calculated on the basis of the amount of a reasonable royalty which would have been payable by a licensee or sublicensee in respect of the patent concerned.[subsection (6) added by section 3(c) of Act 76 of 1988]

66. Restriction on recovery of damages for infringement

(1)A patentee shall not be entitled to recover damages in respect of infringement of a patent from a defendant who proves that at the date of the infringement he was not aware, and had no reasonable means of making himself aware, of the existence of the patent, and the marking of an article with the word "patent" or "patented" or any word or words expressing or implying that a patent has been obtained for the article, stamped, engraved, impressed on or otherwise applied to the article, shall not be deemed to constitute notice of the existence of the patent unless such word or words are accompanied by the number of the patent: Provided that nothing in this section shall affect any proceedings for an interdict.

(2)Any person who represents that any invention is patented, without such representation disclosing the number of the patent concerned, and from whom the number of such patent has been requested in writing by registered post by any other person unaware of such number, may not recover from such other person damages, or obtain an interdict against him, in respect of any infringement of such patent by such other person, committed during the period commencing with the representation and terminating two months after the date on which such other person was notified in writing by the first-mentioned person of the number of the patent concerned.

(3)Any person who, having made a request referred to in subsection (2), expends during the period referred to in that subsection, any money, time or labour with a view to making, using, exercising or disposing of the, invention, may apply in the manner prescribed to the commissioner for compensation in respect of the money, time or labour reasonably so expended, and the commissioner may issue such order as he may deem fit.

67. Presumptions in relation to new substances

(1)A claim in respect of a patent for a process or an apparatus for producing any product shall be construed as extending to such product when produced by the process or apparatus claimed.

(2)If the invention for which a patent is granted is a process for obtaining a new product, the same product produced by a person other than the proprietor of the patent or a licensee under that patent shall, unless the contrary is proved, be deemed, in any proceedings, to have been obtained by that process.

(3)In considering whether any person has discharged the onus imposed upon him by subsection (2), the commissioner shall not require him to disclose any secret process used by him in producing the product concerned, if it appears to the commissioner that it would be unreasonable to do so.

68. Relief for infringement of partially valid specification

Where in any proceedings for infringement of a patent, the commissioner finds that any claim in the complete specification in respect of which infringement is alleged, is valid, but that any other claim therein is invalid, the following provisions shall, notwithstanding anything contained in section 66(5), apply, namely—

(a)If a counterclaim for the revocation of the patent has been made in the proceedings on the ground of the invalidity of any claim in the specification, the commissioner may postpone the operation of any order issued thereon for such time as may be required to enable the patentee to effect any amendment of the specification pursuant to the conditions imposed by the commissioner, who may attach such other condition to any order to be issued on the counterclaim as he may deem fit; and

(b)when the specification has been amended in terms of paragraph (a), the commissioner may, subject to such order as to costs as he may issue and as to the date from which damages shall be calculated, grant relief in respect of any claim which had, before the amendment, been found to be valid and infringed, and in exercising his discretion he may take into consideration the conduct of the patentee in inserting in the specification those claims which had been found, before amendment, to be invalid or permitting such claims to remain there.

69. Declaration as to non-infringement

(1)A declaration that the use by any person of any process, or the making or use or sale by any person of any article, does not or would not constitute an infringement of a patent, may be made by the commissioner in proceedings between that person and the patentee or an exclusive licensee mentioned in section 56(11), notwithstanding that no assertion to the contrary has been made by the patentee or licensee, if it is proved—

(a)that such person has applied in writing to the patentee or licensee for a written acknowledgement to the effect of the declaration claimed, and has furnished him with full particulars of the process or article in question; and

(b)that the patentee or licensee has failed to give such an acknowledgement.

(2)The costs of all parties to proceedings for a declaration instituted by virtue of this section shall be awarded in such manner as the commissioner may deem fit.

70. Remedy for groundless threats of infringement proceedings

(1)Where any person, by circular, advertisement or otherwise, threatens any other person with proceedings for infringement of a patent, a person aggrieved thereby may, whether the person making the threats is or is not entitled to or interested in a patent or an application for a patent, institute proceedings against him and obtain a declaration to the effect that such threats are unjustifiable and an interdict against the continuance of such threats, and may recover such damages, if any, as he has sustained thereby, unless the person making the threats proves that the acts in respect of which the proceedings are threatened, constitute or, if done, would constitute an infringement of a patent in respect of a claim in the specification which is not shown by the plaintiff to be invalid: Provided that a circular, advertisement or communication addressed to any person, which comprises only a notification of the existence of a particular patent upon which the proprietor relies for protecting his interests shall not, by itself, be deemed to be a threat of proceedings for infringement.

(2)The defendant in any such proceedings may apply by way of a counterclaim in the proceedings for any relief to which he would be entitled in separate proceedings in respect of any infringement by the plaintiff of the patent to which the threat relates.

71. Special provisions as to vessels, aircraft and land vehicles of convention countries

(1)Subject to the provisions of this section, the rights of a patentee shall not be deemed to be infringed—

(a)by the use on board a convention vessel of the patented invention in the body of the vessel or in the machinery, tackle, apparatus or other accessories thereof, if the vessel comes into the territorial waters of the Republic temporarily or accidentally only, and the invention is used exclusively for the actual needs of the vessel; or

(b)by the use of the patented invention in the construction or working of a convention aircraft or land vehicle or accessories thereof if the aircraft or vehicle comes into the Republic temporarily or accidentally only.

(2)For the purposes of this section, vessels and aircraft shall be deemed to be vessels and aircraft of the country in which they are registered, and land vehicles shall be deemed to be vehicles of the country within which the owners are ordinarily resident.

(6)The communication of any such invention to the Minister of Defence or to any person authorized by him to inquire into the invention shall not, nor shall anything done for the purpose of the inquiry by such person, be deemed to be publication or use of the invention so as to prejudice the grant or validity of any patent for the invention.

(7)The Minister of Defence may by notice in writing to the registrar direct that any invention directed to be kept secret need no longer be kept secret, and thereupon the specification and drawings may be published.
