(2) The application must be made in the prescribed form, and must be left at, or sent by post to, the Registrar in the prescribed manner.

(3) The application must contain a declaration to the effect that the applicant is in possession of an invention, whereof he, or in the case of a joint application one at least of the applicants, claims to be the true and first inventor, and for which he desires to obtain a patent, and must be accompanied by either a provisional or complete specification.

(4) The declaration required by this section may be either a statutory declaration or not, as may be prescribed.

4. (1) A provisional specification must describe the nature of the invention.

(2) A complete specification must particularly describe and ascertain the nature of the invention and the manner in which the same is to be performed.

(3) In the case of any provisional or complete specification where the Registrar deems it desirable he may require that suitable drawings shall be supplied with the specification, or at any time before the acceptance of the same, and such drawings shall be deemed to form part of the said specification.

(4) A specification, whether provisional or complete, must commence with the title, and in the case of a complete specification must end with a distinct statement of the invention claimed.

(5) Where the invention in respect of which an application is made is a chemical invention, then, subject to L~e prescribed rules, typical samples and specimens shall, if in any particular case the Registrar considers it desirable so to require, be furnished before the acceptance of the complete specification, and the applicant shall be at liberty, where he so desires, and subject to the prescribed rules, so to furnish any typical samples and specimens, unless the Registrar in any particular case considers that it is undesirable that any should be received.

5. (1) The Registrar shall refer, if he thinks fit, any application Proceedings to an examiner. ~gglication.

(2) If the Registrar is of opinion, or if, after reference to an [30 of 19491 examiner, the examiner reports that the nature of the invention is not fairly described, or as respects a complete specification that the nature of the invention or the manner in which it is to be performed is not therein particularly described and ascertained, or that the application, specification, or drawings have not been prepared in the prescribed manner, or that the title does not sufficiently indicate the subject-matter of the invention, the Registrar may refuse to accept the specification or require that the application, specification, or drawings be amended before he proceeds with the application; and in the latter case the application shall, if the Registrar so directs, be deemed to have been made on the date on which the requirement is complied with.

(3) The Registrar may, where the application was accompanied by a specification purporting to be a complete specification, if the applicant so requests, treat the specification as. a provisional specification and proceed with the application accordingly.

(4) The Registrar may, where the applicant before acceptance of the complete specification so requests and upoP-. payment by the applicant of the prescribed fee, direct that the application shall be deemed to have been made on such date within a period of six months running from the date when the application was actually made, as the applicant may request.

(5) The applicant may appeal from any decision of the Registrar under this section to the Appeal Tribunal who shall, if required, hear the applicant and the Registrar, and may make an order determining whether and subject to what conditions (if any) the specification shall be accepted.

(6) The Registrar shall, when a specification has been accepted, give notice thereof to the applicant.

6. An invention may, during the period between the date of an application for a patent therefor and the date of sealing a patent on that application, be used and published without prejudice to that patent, and such protection from the consequences of use and pUblication is in this Act referred to as provisional protection.

In this section the expression "date of an appiication for a patent" means, as respects an application which is post-dated or ante-dated under this Act, the date to which the applic:tion is so post-dated or ante-dated, and means, as respects any other application, the date on which it is actually made.

Comparison of prov~sjonal and complete specification.

~. (1) Where a c;)Il,.plete specification is lefe after a provisional specification, the Registrar may, if he thinks fit, refer ~oth specifi7 cations. to an examiner.

(2) If the Registrar is of opinion, or if, after reference to an examiner, the examiner reports that the nature of the invention or the manner in which it is to be performed is not particularly described and ascertained in the complete specification or that the complete specification or drawings have not been prepared in the prescribed manner, the Registrar may refuse to accept the complete specification until it has been amended to his satisfaction.

(3) If the 'Re'gistrar is of opinion, or if, after reference to an examiner, the examiner reports that the invention particularly described i"n the complete specification is not substantially the same as that which is described in the provisional specification the Registrar may-

(a) refuse to accept the compiete 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 shall be deemed to have been made on the date at which the complete specification was left, and proceed with the application accordingly:

Provided that where the complete specification includes an invention not included in the provisional specification the Registrar may allow the original application to proceed so far as the invention included both in the provisional and in the complete specification is concerned, and allow an application for the additional invention included in the complete specification to be made and direct that that application shall be deemed to have been made on the date at which the complete specification was left.

(4) An appeal sha1llie from the decision of the Registrar under this section to the Appeal Tribunal, who shall, if required, hear the applicant and the Registrar and may make an order determining whether and subject to what conditions (if any) the complete -specification shall be accepted.

(2) If on investigation it appears that the invention claimed has been wholly or in part claimed or described in any such speci- 'fication, the applicant shall be informed thereof, and the applicant may, within such time as may be prescribed, amend his specification, and the amended specification shall be investigated in like manner as the original specification.

(3) If the Registrar is satisfied that no objection exists to the -spedfication on the ground that the invention claimed thereby has been wholly or in part claimed or described in a previous specification .as before mentioned, he shall, in the absence of any other lawful ground of objection, accept the specification.

(4) If the Registrar is not so satisfied, he shall, unless the .objection is removed by amending the specification to the satisfaction <:>f the Registrar, determine whether a reference to any, and, if so, what prior specifications ought to be made in the specification by way of notice to the public:

Provided that the Registrar, if satisfied that the invention claimed has been wholly and specifically claimed or wholly and specifically described in any specification to which the investigation has extended, may in lieu of requiring references to be made in the applicam's specification as aforesaid, refuse to grant the application for a patent.

(5) If it is within the knowledge of the Registrar that the invention claimed has been made available to the public by publication in Guyana, before the date which the patent applied for would bear if granted, in any document (other than a Guyana specification or a specification describing the invention for t..1].e purposes of an applic- ation for protection made in any country outside Guyana more than fifty years next before that date, or any abridgment of, or extract from, any such specification published, under the authority of the Registrar or of the Government of any country outside Guyana), the provisions of subsections (2), (3) and (4) shall apply in relation to a claii'll or description of the invention in that document in like manner as those provisions apply in- relation to a description thereof in a prior specification to which the investigation has extended.

(6) An appeal shall lie from the decision of the Registrar under this section to the Appeal Tribunal.

10. (1) In addition to the investigation under the last preceding section, the Registrar, or, if the application has been referred to an examiner; the examiner shall make an investigation for the PUl. jJose of ascertaining whether the invention claimed has been wholly or in part claimed in any specification published on or after the date which the patent applied for would bear if granted and deposited pursuant to an application made in Guyana for a patent which if granted would bear prior date to the date which the patent applied for woule bear if granted.

(2) Where OIi such further investigation it appears that the invention claimed has been wholly or in part claimed in any such specification, the applicant shall, whether or not his specification has been accepted or a patent granted to him, be afforded such facilities as may be prescribed for amending his specification, and in the event of his failing to do so the Registrar shall, in accordance with such procedure as may be prescribed, determine what reference, if any, to other specifications ought to be made in his specification by way of notice to the public.

(3) An appeal shall lie from the decision of the Registrar under this section to the Appeal Tribunal. .

(4) The. investigations and reports required by this and the last preceding section shall not be held in any way to guarantee the validity of any pa,tent and no liability shall be incurred by the

Government or any officer thereof by reason of or in connection with any such investigation or report or any proceedings consequent thereon.

(4) If the application is in order before the expiration of twenty-one months from the date thereof and within the said period, upon a request for postponement being made by the applicant before the complete specification has been accepted,and, in the case of a request for postponement to a date later than eighteen months from the date of the application, upon payment of the prescribed fee, the Registrar may postpone acceptance of the specification to such date, not being later than the expiration of twenty-one months from the date of the application, as may be specified in the request, or, where more than one such request has been made, as may be specified in the last request.

(5) The period allowable for the purposes of this section shall be a period of eighteen months from the date of the application:

Provided that- (a) the applicant may give notice to the Registrar that he

desires the said period to be extended to nineteen, to twenty or to twenty-one months from the date of the application, and if he gives such a notice and pays the prescribed fee within the period specified in the notice, that period (or where more than one such notice has been given, the period specified in the last notice) shall be the period allowable;

(b) if at the expiration of the period which would otherwise be the period allowable by virtue of the foregoing provisions of this subsection the last day has not passed on which an appeal

Term of patent. [30 of 1949 4 of 1972]

(2) Every patent may be in the prescribed form and shall be granted for one invention only, but the specification may contain more than one claim; and it shall not be competent for any person in an action or other proceeding to take any objection to a patent on the ground that it has been granted for more than one il1Vention.

19. (1) A patent granted on the application of the true and first Fra~du[~n.t inventor shall not be invalidated by an application in fraud of him, ;g!,~~~:~~~ or by provisional protection obtained thereon, or by any use or . . publication of the invention subsequent to that fraudulent application during the period of provisional protection.

(2) Where a patent has been revoked by the Court on the ground that it has been obtained in fraud of the true and first inventor, or where the grant has been refused by the Registrar under section 14 (1) (a), or revoked on the same ground under section 30, the Registrar may, on the application of the true inventor made in accordance with this Act, grant to him a patent for the whole or any part of the invention in lieu of and bearing the same date as the patent so revoked, or as -would have been borne by the patent if the grant thereof had not been refused.

(3) Where in proceedings before the Registrar under this Act for opposition to the grant of a patent or for revocation of a patent, the Registrar has found that an invention was in part obtained from the opponent or the applicant for revocation and has required that the specification be amended by exclusion of that part of the invention, he may, on the application of the true inventor made in accordance with this Act, grant to him a patent for that excluded part of the invention bearing the date of the opposed application or the date of the patent sought to be revoked as the case may be.

(4) No action shall be brought for any infringement of a patent granted under either of the last two foregoing subsections committed before the date of sealing the patent.

20. (1) Where the same applicant has put in two or more pro- visional specifications for inventions which are cognate or modifi- cations one of the other, and has obtained thereby concurrent provisional protection for the same, and the Registrar is of opinion that the whole of such inventions are such as to constitute a single invention and may properly be included in one patent, he may accept one complete specification in respect of the whole of such applications and grant a single patent thereon.

(2) Such patent shall bear the date of the earliest of such applications, but in considering the validity of the same, and in determiping other questions under this Act, the Court or the Registrar, as the case may be, shall have regard to the respective dates of the provisional specifications relating to the several matters claimed in the complete specification.

TERM OF PATENT

21. (1) The term liroited in everj patent for the du::ation thereof shall, save as otherwise expressly provided by this Act, be a term beginning on the date of the patent and ending at the expiration of sixteen years from the date (to be entered in the register of patents) on which the specification accepted as a complete specification is treated by the Registrar as having been first left.

(2) Any patent the original term of which had not expired at the date of the commencement of this Act shall have effect as if the term mentioned therein was sixteen years instead of fourteen years, subject to the following conditions-

(a) any licence existing at that date which has been granted for the term of the patent shall be treated as having been granted for the term as· so extended if the licensee so desires;

(b) if the patent would, apart from this section, have expired on or before the commencement of this Act, the patent shall, during the period of extension, be subject to all the provisions of section 28 (except subsection (5) thereof) as if the patent had been endorsed "licences of right".

(3) Where any party to a contract with the patentee or any other person, entered into before the commencement of this Act, is

subjected to loss or liability by reason of the extension of the term of any patent under this section, the Court shall have power to determine in what manner and by which parties such loss or liability shall be borne.

(4) A patent shall, notwithstanding anything therein or in this Act, cease at the expiration of the period prescribed for the payment of any prescribed renewal fee, unless the patentee pays the fee within that period or within that period as extended under this subsection.

The period prescribed for the payment of any such fee shall from time to time be extended to such period (not exceeding a period three months longer than the prescribed period) as may be specified in a request in that behalf made by the patentee to the Registrar, if the request is made, and the fee and the prescribed additional fee (which shall not exceed one hundred dollars) are paid, within the period so specified.

(5) If any proceeding is taken in respect of an infringement of the patent committed after a failure to pay any renewal fee within the prescribed period, and before any extension thereof, the Court before which the proceeding is proposed to be taken may, if it thinks fit, refuse to award any damages in respect of such infringement.

Page 19

22. (1) A patentee may, after advertising in manner provided by E:tension rules of the High Court his intention to do so, present a petition to ~~::~~ of L'1e Court praying that his patent may be extended for a further [30 of 1949 term, but such petition must be presented at least six months before 4 of 1972j the time limited for the expiration of the patent:

Provided that the Court may allow such a petition to be presented at such time, not being later than the time limited for the expiration of the patent, as the Court may in its discretion think fit.

(2) Any person may give notice to the Court of objection to the extension.

(3) On the hearing of any petition under this section the patentee and any person who has given such notice of objection shall be made parties to the proceeding, and the Registrar shall be entitled to appear and be heard, and shall appear if so directed by the Court.

(4) The Court, in considering its decision, shall have regard to the nature and merits of the invention in relation to the public, to the profits made by the patentee as such, and to all the circumstances of the case.

(5) If it appears to the Court that the patentee has been inadequately remunerated by his patent, t.~e Court may by order extend the term of the patent for a funher term not exceeding five years, or in exce,J onal cases, ten years, or may order the grant of a new patent for such t~rm as may be specified in the order and cClltai:ning an-y restrictions, conditions, and provisions the Court may think fit. .

Page 20

(6) Where, by reason of hostilities between Guyana and any foreign state, the patentee as such has suffered loss or damage (including loss of opportunity of dealing in or developing his invention owing to his having been engaged in work of national importance connected with such hostilities) an application under this section may be made by originating summons instead of by petition, and the Court in considering its decision may have regard solely to the loss or damage so suffered by the patentee:

Provided that this subsection shall not apply if the patentee is a subject of such foreign state as aforesaid, or is a company the business whereof is managed or controlled by such subjects or is carried on wholly or mainly for the benefit or on behalf of such subjects, notwithstanding that the company may be registered within the Commonwealth.

(7) Where an application is made under subsection (6)- (a) the power conferred on the Court by the proviso to

subsection (1) to allow th.e application to be made at such time as the Court may in its discretion think fit shall be exercisable free from the restriction imposed by that proviso that the time allowed must be not later than the time limited for the expiration of the patent, if the Court is satisfied that the allowance of a time later than the expiration thereof is justified by the patentee's having been prevented from making the application by being on active service or by other circumstances arising by reason of hostilities between Guyana and any foreign state;

(b) an order may be made notwithstanding that the term of the patent may have been previously extended, or that a new patent for the invention may have been previously granted, by one or more orders made under this section, and notwithstanding that the previous order, or one of the previous orders, may have been made otherwise than pursuant to an application under subsection (6);

(c) the restriction imposed by subsection (5) of this section on the length of the further term for which a patent may be extended shaIl not have effect, but the term granted by an order, whether by way of extension or grant of a J;lew patent, shall not exceed ten years, and, where two or more orders are made pursuant to applications under subsection (6) in relation to the same invention, the aggregate of the terms thereby granted, whether by way of extension or grant of a new patent, shall not exceed ten years.

(8) In any case where an application could be made to the Court under subsection (6)--

(a) the application may, at the option of the patentee, be made in the prescribed manner to the Registrar instead of to the Court, and the foregoing provisions of this section shall apply, so far as applicable and subject to the necessary modifications, to such an application in li..~e manner as they apply to an application to the Court 1IDder the said subsection (6), except that the requirement imposed on an applicant by subsection (1) to advertise his intention to make the application shall be dispensed \vith;

(b) if the Registrar considers that the application raises issues of a kind that would ce more fittingl] de:::ided by the Court, he may, if he thinks fit, refer the application for decision by the Court;

23. (1) Wnere a patent for an invention has been applied for or granted, and the applicant or the patentee, as the case may be, applies for a further patent in respect of any improvement in or modification of the invention, he may, if he thinks fit, in his applic- ation for the further patent, request that the term limited in that patent for the duration thereof be the same as that of the original patent or so much of that term as is unexpired.

(2) Where an application containing such a request is made, a patent of addition may be granted for such term as aforesaid.

(3) Where an invention, being an improvement in or modi.fi.~ cation of an original IDvention, is the subject of an independent patent and the patentee in respect of the independent patent, being also the patentee in respect of the patent for the original invention, so requests, the Registrar may make an order for the revocation of the independent patent and a patent of addition may be granted in respect of the improvement or modification bearing the same date as the date of the independent patent so revoked.

(4) A patent of addition shall remain in force during the term limited in the patent for the original invention or until the previous cesser thereof and no longer, but may be extended under the last foregoing section fer any period for vvhich the patent for the original

invention is extended thereunder, and in respect of a patent of addition no fees shall be payable for renewal:

Provided that, if the patent for the original in-v'ention is revoked, then the patent of addition shall, if the Court or Registrar so orders, become an independent patent, and the fees payable, and the dates when they become payable, shall be determined by its date, but its duration shall not exceed the unexpired term of the patent for the original invention.

(5) The grant of a patent of addition shall be conclusive evidence that the invention is a proper subject for a patent of addition, and the validity of the patent shall not be questioned on the ground that the invention ought to have been the subject of an independent patent.

RESTORATION OF LAPSED PATENTS

24. (1) Where any patent has become void owing to the failure of the patentee to pay any prescribed fee within the prescribed time, the patentee may apply to the Registrar in th.,; prescribed manner for an order for the restoration of the patent.

(5) The decision of the Registrar in either case shall be sub- ject to an appeal, where the person making the request to amend is a patentee, to the Court, and, where the person making the request to amend is an applicant for a patent, ·to the Appeal Tribunal and the Court or the Tribunal, as the case may be, shall, if required, hear the

. person making the request to amend, and, where notice of opposition has been given the person giving that notice, if he is in the opinion of the Court or of the Tribunal, as the case may be, entitled to be heard in opposition to the request, and, where there is no opposition, the Registrar, and may make an order determining whether and subject to what conditions (if any) the amendment ought to be allowed.

(6) No amendment shall be allowed that would make the 'specification, as amended, claim an invel),tion substantially larger

. than or substantially different from the invention claimed by the specification as it stood before amendment.

(7) Leave to amend shaH be conclusive as to the right of the party to make the amendment allowed, except in case of fraud; and the amendment shall be advertised in the prescribed manner, and shall in all courts and for all purposes be deemed to fonn part of the specification:

Provided that no amendment shall be so allowed that would make the specification, as amended, claim an invention substantially larger than, or substantially different from, the invention claimed by the specification as it stood before the amendment, and where an appli- cation for such an order is made to the Court notice of the application shall be given to the Registrar, and the Registrar shall have the right to appear and be heard, and shall appear if so directed by the Court.

27. Where an amendment of a specification by way of disclaimer, correction, or explanation, has been allowed under this Act, no damages shall be given in any action in respect of the use of the invention before the date of the decision allowing the amendment, unless the patentee establishes to the satisfaction of the Court that his original claim was framed in good faith and with reasonable skill and knowledge.

COMPULSORY LICENCES AND REVOCATION

28. (1) At any time after the sealing of a patent the Registrar shall, jf the patentee so requests, cause the patent to be endorsed with the words "licences of right", and a corresponding entry to be made in the register, and thereupon-

(a) any person shall at any time thereafter be entitled as of right to a licence under the patent upon such terms as, in default of agreement, may be settled by the Registrar on the application of either the patentee or the applicant:

Provided that any licence the terms of which are settled by agreement shall be deemed, unless otherwise expressly provided, to include the terms and conditions specified in paragraphs (c) and (d) as if they had been·imposed by the Registrar thereunder in like manner as if the terms had been settled by the Registrar;

(b) in settling the terms of any such licence the Registrar shall be guided by the following considerations-

(i) he shall, on the one hand, endeavour to secure the widest possible user of the invention in Guyana consistent with the patentee deriving a reasonable advantage from his patent rights;

(ii) he shall, on the other hand, endeavour to secure to the patentee the maximum advantage consistent with the invention being worked by the licensee at a reasonable profit in Guyana;

(iii) he shall also endeavour to secure equality of advantage among the several licensees, and for this purpose may, on due cause being shown, reduce the royalties or other payments accruing to the patentee under any licence previously granted: Provided that, in considering the question of equality of

advantage, the Registrar shall take into account any work done or outlay incurred by any previous licensee with a view to testing the commercial value of the invention or to securing the working thereof on a commercial scale in Guyana.

Page 23

Page 24

(c) any such licence the terms of which are settled by the Registrar may be so framed as to preclude the licensee from importing into Guyana any goods the importation of which, if made by persons other than the patentee or those claiming under him, would be an infringement of the patent, and in such a case the patentee and all licensees under the patent shall be deemed to have mutually covenanted against such importation;

(d) every such licensee shall be entitled to call upon a patentee to take proceedings to prevent the infringement of the patent, and if the patentee refuses, or neglects to do so within two months after being so called upon, the licensee may institute proceedings for the infringement in his own name as though he were patentee, making tl1e patentee a defendant. A patentee so added as defendant shall not be liable for any costs unless he enters an appearance and takes part in the proceedD.igs. Service on him may be effected by leaving the writ at his address for service given on the register;

(e) if in any action for infringement ofa patent so endorsed the infringing defendant IS ready and willing to take' a licence upon terms to be settled by the Registrar, no injunction against him shan be awarded, and the 'amount recoverable against him by way of damages (if any) shall not exceed double the amount which would have been recoverable against rJm as licensee if the licence had been dated prior to the earliest infringement:

Provided that this paragraph shaH not apply where the infringement consists of the importation of infringing ~oods;

(f) the renewal fees payable by the patentee of a patent so endorsed shall, as from the date of the endorsement, be one moiety only of the fees which would otherwise have been payable.

(2) The Registrar shall, before acting on any request to endorse a patent made by the patentee li...llder this section, advertise such request in the Gazette and shall satisfy himself that the patentee is not precluded by contract from making such request, and for that purpose shall require from tnepatentee such evidence, by statutory declaration or otherwise, as he may deem necessary:

Provided that a patentee shaH not be deemed to be so precluded by reason only of his having granted a licence under the patent where the licence does not limit his right to grant other licences.

(3) Any person, alleging that a request under this section has. been made contrary to some contract in which he is interested, may apply to the Registrar within the prescribed time and in the prescribed manner, and the Registrar, if satisfied of the truth of such allegation. shall refuse to endorse the patent pursuant to the request or shall cause the endorsement, if already made, to be cancelled.

(4) Where a patent of addition is in force any request made under this section for an endorsement either of the original patent or of the patent of addition shall be treated as a request for the endorse- ment of both patents, and if refused as respects the one shall be refused as respects the other also, and where a patent of addition is granted in respect of a patent which is endorsed under this section the patent of addition shall also be so endorsed.

(5) All endorsements of patents under this section shall be entered on the register of patents and shall be published in the Gazette, and in such other manner as to the Registrar may seem desirable for the purpose of bringing the invention to the notice of manufacturers.

(6) The Registrar may, if he thinks fit, on the application of the patentee and on payment by him of the unpaid moiety of all renewal fees which have become due since the endorsement, cancel the endorsement, and in that case the patentee's rights and liabilities shall be the same as if no such endorsement had been made:

Provided that before acting on any application for the cancellation of an endorsement, the Registrar shall advertise the application in the prescribed manner and shall satisfy rumself that there is no existing licence or that all existing licensees consent to the application.

(7) Any person may within the prescribed time and in the prescribed manner, give notice at the Patent Office of opposition to an application for the cancellation of an endorsement, and where any such notice is given the Registrar shall, after giving notice of the opposition to the applicant and after giving to the applicant and to the opponent an opportunity of being heard, decide on the case.

monopoly rights ta'1e:-eunder and asking for relief under this section. [~ih~f 1949] (2) The monopoly rights under a patent shall be deemed to

have been abused in any of the following circumstances-

(a) if t..'1e patented invention (being one capable of being worked in Guyana, is not being worked within Guyana on a cOIT'L.1TI.ercial scale, and no satisfactory reason can be given for such non-working:

Provided that, if an application is presented to the Registrar on this ground, and the Registrar is of opinion that the time which has elapsed since the sealing of the patent has by reason of the nature of the invention or for any other cause been insufficient to enable the invention to be worked within Guyana on a corrunercial scale, the Registrar may make an order adjourn- ing the application for such period as will in his opinion be sufficient for that purpose;

(b) if the working of the invention within Guyana on a com- mercial scale is being prevented or hindered by the importation from abroad of the patented article by the patentee or persons claiming under h1.'ll, or by persons directly or indirectly purchas- ing from him, or by other persons against whom the patentee is not taking or has not taken any proceedings for infringement;

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

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

(e) if any trade or industry in Guyana, or any person or class of persons engaged therein, is unfairly prejudiced by the condi- tions attached by the patentee, whether before or after the passing of this Act, to the purchase, hire, licence, or use of the patented article, or to the using or working of the patented process;

Provisions as to unfair exercise of process patent.

(f) if it is shown that the existence 01 the patent, oemg a patent for an invention relating to a process involving the use of materials not protected by the patent or for an invention relating to a substance produced by such a process, has been utilised by the patentee so as unfairly to prejudice in Guyana the manu- facture, use or sale of any such materials:

Provided that, for the purpose of determining whether there has been any abuse of the monopoly rights under a patent, it shall be taken that patents for new inventions are granted not only to encourage invention but to secure that new inventions shall so far as possible be worked on a commercial scale in Guyana without undue delay.

(3) On being satisfied that a case of abuse of the monopoly rights under a patent has been established, the Registrar may exercise any of the following powers as he may deem expedient in the circum- stances:

(a) he may order the patent to be endorsed with the words "licences of right" and thereupon the same rules shall apply as are provided in this Act in respect of patents so endorsed, and an exercise by the Registrar of this power shall entitle every existing licensee to apply to the Registrar for an order entitling him to surrender his licence in exchange for a licence to be settled by the Registrar in like manner as if the patent had been so endorsed at the request of the patentee, and the Registrar may make such order; and an order that a patent be so endorsed may be made notwithstanding that there may be an agreement subsisting which would have precluded the endorsement of the patent at the request of the patentee;

(b) he may order the grant to the applicant of a licence on such terms as the Registrar may think expedient, including a term precluding the licensee from importing into Guyana any goods the importation of which, if made by persons other than

the patentee or persons claiming under i',m1, would be an infringe- ment of the patent, and in such case the patentee and all licensees for the time being shall be deemed to have mutually covenanted against such importation. A licensee under this paragraph shall be entitled to call upon the patentee to take proceedings to prevent infringement of the patent, and if the patentee refuses, or neglects to do so within two months after being so called upon, the licensee may ins.titute proceedings for infringement in his own name as though he were the patentee, making the patentee a defendant. A patentee so added as defendant shall not be liable for any costs unless he enters an appearance and takes part in the proceedings. Service on him. may be effected by leaving the writ at his address for service given on the register.

lil settling the terms of a licence under this paragraph the Registrar shall be guided as far as may be by the same considera- tions as are specified in section 23 for ris guidance in settling licences under that section;

(c) if the Registrar is satisfied that the invention is not being worked on a comlTIercial scale· in Guyana, and is such that it cannot be so worked without the expenditure cf capital for the raising of which it will be necessary to rdy on the patent mono- poly, he may, unless the patentee or those clairning under him ",rill undertake to find su;;h capital, order the grant to' the appli- cant, or any other person, or to the applicant and any ether person or persons jointly, jf able and willing to provide suer.

capital, of an exclusive licence on such terms as the Registrar may think just, but subject as hereinafter provided;

(d) if the Registrar is satisfied that the m.onopoly r:.ghts have been abused in the circumstances specified in paragraph. (f) of the last preceding subsection, he may order the grant of licences to the applicant and to such of his customers and cor:- taining such terms as the Registrar may LlUnk expedient;

(e) if the Registrar is of opinion that objects of this section will be best attained by making no order under the aboye provisions of ihis section, he may make an order refusing fue. application and dispose of any question as to costs t.1J.ereon as he thinks just.

(4) In settlliig the terms of any Budy e~clusi'fe licence as is provided in paragraph (c) of the last preceding subsection, due regard shall be had to the risks llndertaken by the licensee in providing tile capital and 'Working the invention, but, subject thereto, the licence shall be so framed as-. .

(a) to secure to the patentee the maXimUil1 royalty com- patible with the licensee working the invention in Guyana on 2. commercial scale and at a reasonabie profit;

(0) to guarantee to the patentee a rr.tinimum yearly sum by way of royalty, if and so far as it is reasonable so to do, having regard to the capital requisite for the proper working of the invention and all the cirCuilistances of the case;

a.l"ld, in additicn to any ot.lJ.er powers expressed in the licence or- order, the licence and the order granting the licence shall be made revocable at the discretion of the Registrar if 6e licensee fails to expend the amount specified in the licence as being the amount which he is able and willing to provide for the purpose of working the invention on a COIllitiercial scale within Guyana, or if he fails so to work the L'lvention within the thile specified in the order.

(5) In deciding to whom such an exclusive licence is to be granted the Registrar shall, unless good reason is shown to the contrary, prefer an existing licensee to a person having no registered interest in the patent.

(6) The order granting an exclusive licence under this section shall operate to take away from t.ile patentee any right which he may have as patentee to work or use the invention and to revoke all existing licences, unless otherwise provided in the order, but on granting an exclusive licence the Registrar may, if he thinks it fair and equitable, make it a condition that the licensee shall giye proper compensation to be fi'{ed by the Registrar for any money or labour expended by the patentee or any existing licensee in developing or- exploiting the invention.

(7) If an application is made under subsection (1) in relation to a patent, and-

(a) an order has already been made in relation to that patent under subsection (3) (b), (e) or (d);

(0) a period of not less than two years has elapsed between the date of that order and the date of the application; and

(c) the Registrar is satisfied that the objects of this section cannot be attained by the exercise of any of the powers conferred by the said subsection (3),

Page 29

the Registrar may order the patent to be revoked, either forthwith,. or after such reasonable interval as may be specified in the order, unless in the meantime such conditions as may be prescribed in the order with a view to attaining the objects of this section are fulfilled,. and the Registrar may, on reasonable cause shown in any case, by- subsequent order extend the interval so specified:

Provided that the Registrar shall make no order for revocation which is at variance with any treaty, convention, arrangement or engagement subsisting between Guyana and any Commonwealth. territ0ry 0I any foreign country.

The application must be accompanied by statutctY. declarations verifying the applicant's interest and the facts set out in the application.

(9) The Registrar shall consider the matters alleged in the application and declarations, and, if satisfied that the applicant has a bona fide interest and that a prima facie case for relief has been made out, he' shall direct the applicant to serve copies of the appli- cation and declarations upon the patentee and upon any other persons appearing from the register to be interested in the patent and shall advertise the application in the Gazette.

(10) If tile patentee OJ any person is desirous of opposing the granting of any relief under this section, he shall, within such time as may be prescribed or within such extended time as the Registrar may on application (made either before or after the expiration of the prescribed time) further allow, deliver to the Registrar a counter statement verified by a statutory declaration fully setting out the grounds on which the application is to be opposed.

(11) The Registrar shall consider the counter statement and declarations in suppcn thereof and may thereupon dismiss the application if satisfied that the allegations in the application have been adequately ans'Nered, unless any of the parties demands a hearing or unless the Registrar himself appoints a hearing. In any case the Registrar may require the 'attendance before hun of any of the dec1arants to be cross-exawjned or further examined upon matters relevant to the issues raised in the application and counter stateme..."'1t, and he may, subject to due precautions against disclosure ofi.J.ifonna- tion to rivals in trade, require the production before him of books and documents relating to the matter in issue.

(12) ..'ill orders of the Registrar Imaer this sec·don shall. be subject to appeal to the Court, and on any such appeal the Attorn.,:;y- General or such ether counsel as he may appoint shall be entitled to appear and be heard.

(13) In any case where the Registrar aces not dismiss an application as hereintefore provided, and

Ca) if th~ parties interested consent; or (b) if the proc:;;dings require any prolonged e~,-a:mination of

cccuments or any scientific or local investigation which. cannot in the opinion of the Registrar ;;onveniently be made before him,

the Registrar may at any time order the whole proceedings or any question or issue of fact arising th~reunder to be referred to an arbitrator agreed on by the pa:iies, or in default of agreement

Right of State to use patented inventions. [30 of 1949]

appointed by the Registrar, and, where the whole proceedings are so referred, the award of such arbitrator shall, if aU the parties consent, be final, but otherwise shall be subject to the same appeal as the decision of the Registrar under this section, and, where a question or issue of fact is so referred, the arbitrator shall report bjs findings to the Registrar.

Provided that any Government department may, by themselves or by such of their agents, contractors, or others as may be authorised in writing by them at any time after the application, make, use or exercise the invention for the services of the State on such terms as may, either before or after the use thereof, be agreed on, with the approval of the Minister responsible for such department, between the department and the patentee, or, in default of agreement, as may be settled in the manner hereinafter provided. And the terms of any agreement or licence concluded between the inventor or patentee and any person other ll1.an a Government department, shall be inoperative so far as concerns the making, use or exercise of the invention for the service of the State:

If in the opinion of the department the disclosure

Page 31

Page 32

to the applicant or the patentee, as the case may be, of the document recording the invention, or the evidence of the trial thereof, if re- quired, would be detrimental to the public interest, it may be made confidentially to counsel on behalf of the applicant or patentee, or to any independent expert mutually agreed upon.

(2) The power of a Governrilent department under subsection (1) to make, use or exercise an invention for the services of the State shall include power during any war period to make, use, exercise or vend an invention, upon such terms as are mentioned in the said subsection (1), for any plli-pose which appears to the department necessary or expedient for the efficient prosecution of any war in which the Government. may be engaged or for the maintenance of supplies and services essential to the life of the community; and the terms of any such agreement or licence as is mentioned in the said subsection (1) shall be inoperatiVe so far as concerns the making, use, exercise or vending of an invention under this subsection as they are inoperative so far as concerns the making, use or exercise of an invention under that subsection.

(3) For the purposes of subsection (2) the expression "'war period" means fu'1.y period beginning with such date as may be declared by order of the Minister responsible for defence to be the commencement, and ending with such date as may be so declared to be the termination, of a war period for the purpose of this section; and nothing in subsection (5) of this section shall affect the right to vend an invention conferred by subsection (2).

(a) if the patentee furnishes proof to the satisfaction of the_ Court that the invalid claim was framed in good faith and with reasonable skill and knowledge, or if the patent is dated before the commencement of this Act, the Court shall, subject to its discretion as to costs and as to the date from which damages should be reckoned, and to such terms as to amendment of the specification as it may deem desirable, grant relief in respect of any valid claim which is infringed"without regard to the invalidity of any other claim. in the specification and in exercising such discretion the Court may take into consideration the conduct of the parties in inserting the invalid claim in the specification or permitting that claim to remain there;

(b) if the patentee does not furnish proof as aforesaid, and the patent is dated after the commencement of this Act, the Court shall not grant any relief by way of damages or costs, but may grant such other relief in respect of any valid claim. which is infringed as to the Court seems just, and may impose such terms as to amendment of the specification as a condition of granting any such relief as it may deem desirable;

(c) if a counter-claim for revocation of the patent has been made in the action on the ground of the invalidity of any claim

in the specification, the Court may postpone the operation of any order made thereon during such time as may be requisite for enabling the patentee to effect any amendment of the speci- fication pursuant to terms imposed upon him and may attach any such other condition to any order to be made on the counter- claim as the Court may deem desirable.
