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

Registrar considers it desirable so to require, be furnished before the 
acceptance of the complete specification, and the applicant shall be

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

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

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. 
7. (1) If the applicant does not leave a complete specification with 
his application, he may leave it at any subsequent time within the 
period allowable under subsection (2). 
(2) The period allowable for leaving a complete specifi­
cation shall be a period of twelve months from the date of the 
application: 
Provided that the said twelve months shall be extended to such 
period, not exceedi;}g thirteen months from the date of the appli­
cation, as may be specified in a request made by the applicant to the 
Registrar if the request is made and the prescribed fee is paid within 
the period specified ..

~. (1) Where a c;)Il,.plete specification is left 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. 
9. (1) "''here an application for a patent has been made and a 
complete specification has been left, the Registrar, or if, the applic­
.ation has been referred to an examiner, the examiner shall, in addition 
to the other inquiries which he is directed to make by this Act, make 
.a further investigation for the purpose of ascertainjng whether the 
invention claimed has been wholly or in part claimed or described 
in any specification (other than a provisional specification not 
followed by a complete specification) published before the date which 
the patent applied for would bear if granted and left pursuant to any 
application for a patent made in Guyana and dated within fifty years 
next before such date. 
(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. Investigation

application. (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 would 
bear if granted. 
(2) Where oa 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. IPlNlllGUYlIll

(2) If the application is not in order within that period, it 
shall become void at the expiration of twenty-one months from the 
date thereof or at the expiration of that period, whichever is the later. 
(3) Subject to subsection (4), if the application is in order 
within that period, the complete specification may be accepted at any 
time after the application is in order, and, if not accepted before the 
expiration of that period, shall be accepted as soon as may be 
thereafter. 
(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

fication describing the invention for the purpose of an application 
for protection made in any country outside Guyana more than 
fifty years next before such 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

apply to the Registrar in the prescribed manner for a certificate that 
the claimant ought not to have been so mentioned and the Registrar IPIN/1/GUY/I/1

(b) applications for patents made before, as well as to 
applications made on or after, the 31st Dec,ember, 1949. 
16. (1) If there is no opposition, or, in case of opposition, if the Gr~t and 
determination is in favour of the grap.t of a patent, a patent shall, on ~~eci: of 
payment of the prescribed fee, be granted to the applicant, or in the [30 of 1949] 
case of a joint application to the applicants jointly, and the Registrar 
shall cause the patent to be sealed in duplicate with the seal of the 
Patent Office and one duplicate shall be retained and filed in the 
Patent Office: 
Provided that-
(a) where an applicant under ajoint application has died, the 
patent may, with the consent of his personal representative, be 
granted to the survivors or survivor of the joint applicants; 
(b) where an applicant has agreed in writing to assign the 
patent when granted or, in the case of a joint application, his 
interest in the patent when granted, the patent may, upon proof 
of the agreement to the satisfaction of the Registrar, be granted 
to the assignee or, in the case of an assignment by a joint 
applicant of his interest to an assignee not being the other joint 
applicant, to the assignee jointly with the other applicant or his 
assignee. 
(2) Where disputes arise between joint applicants or their 
assigns as to proceeding with an application, the Registrar, if satisfied 
that one or more of such persons ought to be allowed to proceed 
alone, may allow him or them to proceed with the application and 
may grant a patent to him or them, so, however, that all parties 
interested shall be entitled to be heai-d before the Registrar. 
(3) An appeal shall lie from the decision of the Registrar 
under this section to the Appeal Tribunal.

(a) where the period for the leaving of the complete speci­
fication has been extended beyond twelve months from the date 
of the application, or the period within which the application 
must be in order is longer than eighteen months from that date, 
or the acceptance of the complete specification has been post­
poned under section 11 (4) to a date later than the expiration of 
eighteen months from that date, the patent may be sealed 
within twenty-five months from that date; (b) where the sealing of a patent is delayed by an appeal to 
the Appeal Tribunal or by any proceedings taken for obtaining 
the decision of the Registrar under subsection (2), or by 
opposition to the grant of the patent, or by a request or claim 
under section 15, that patent and any patent of addition the

sealing of that patent may be sealed at such time as in the first­
mentioned case the Tribunal, or· in any other such case as 
aforesaid the Registrar, may direct; 
(c) where the patent is granted to the legal representative of 
an applicant who has died before the expiration of the time

prescribed fee is paid within that longer period: 
Provided that the period so allowed as aforesaid for the sealing of 
a patent shall not be extended under this subsection by more than

allowable in that case by or under subsections (4) and (5) has been 
allowed, and it is proved to the satisfaction of the Registrar that 
hardship would arise in connection with the prosecution by an 
applicant of an application for a patent in any country outside 
Guyana unless that period is extended, that period may be extended 
from time to time to such longer period as appears to the Registrar 
to be necessary in order to prevent that hardship arising if an 
application in that behalf is made to him, and the prescribed fee is 
paid, within the first mentioned period, or in the case of a second or 
. subsequent application under this subsection within the period to 
which thal period was extended on the last preceding application 
thereunder.

[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, :gi~~~!~~: 
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 
L"he 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-IJ>~/1/CJlJJ{/I/1 
J>age 19 
(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. 
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 anal cases, ten years, or may order the grant of a 
new patent for such t~rm as may be specified in the order and 
cOlltai:ning an-y restrictions, conditions, and provisions the Court may 
think fit. . IP/N/1/GUYlIIl 
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 shall 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; Restoration

(c) an appeal shall lie to the Appeal Tribunal from any 
decision of the Registrar on an application made under this 
subsection, and on such an appeal the applicant and any other 
parties to the proceedings shall be entitled to appear and be 
heard, and the Registrar shall also be entitled to appear and be 
heard and shall appear if so directed by the TribunaL 
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 pa.tent 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. 
(2) Every such application shall contain a statement of the 
circumstances wpich have led to the omission of the payment of the 
prescrjbed fee. 
(3) If it appears from such statement that th.e omission was 
unintentional and that no undue delay has occurred in the making 
of the application, the Registrar shall advertise the application in the 
prescribed manner, and within such time as may be prescribed any 
person may give notice of opposition at the Patent Office. 
(4) ¥7here such notice is given the Registrar shall notify the 
applicant thereof. Patents of

(5) Mter the expiration of the prescribed period the Registrar 
shall hear the case and issue an order either restoring the patent or 
dismissing the application: 
Provided that the Registrar may, if he thinks fit, as a condition of 
issuing an order under this 'section restoring a patent require that an 
entry shall be made in the register of patents in respect of any 
document or instrument in respect of which the provisions of this 
Act as to entries in the register have not been complied with. 
(6) In every order under this section restoring a patent such 
provision as may be prescribed shall be inserted for the protection 
of persons who may have availed themselves of the subject matter of 
the patent after the patent has been announced as void in the Gazette. r 
(7) An appeal shall lie from the decision of the Registrar under 
this section to the Court. 
AMENDMENT OF SPECIFICATION 
25. (1) An applicant at any time after acceptance of his complete A ... mend!llent

month from its first advertisement any person may give notice at the 
Patent Office of opposition to the amendment. 
(3) Where such a notice is given the Registrar shall give notice 
of the opposition to the person making the request, and shall hear 
and d~ide the case. 
(4) Where no notice of opposition is given, or the person so 
giving notice of opposition does not appear, the Registrar shall deter­
mine whether and subject to what conditions, if any, the amendment 
ought to be allowed.

before a court for the revocation of a patent the Court may by order 
allow the patentee to amend his spedfication by way of disclaimer, 
correction or explanation in such manner, and subject to such tenus 
as to costs, advertisements or otherwise, as the Court may think fit: 
Provided that no amendment shall be so allowed that would make 
the specification, as amended, claim an invention substantially larger

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.

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. IPINIlIGUY/IIl 
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 
shall 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. Revocation

(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. 
(8) Any decision of the Registrar under this section shall be 
subject to an appeal to the Court.

manner in which the invention is to be performed; . 
(i) that the complete specification does not sufficiently and· 
dearly ascertain the scope of the ·monopoly claimed; 
(j) that the complete specification does not disclose the best 
method of performance of the invention known to the applicant 
for the patent at the time when the specification was left at the 
Patent Office; , 
(k) that the patent was obtained on a false suggestion or 
repres<!nta tion; 
(1) that the invention claimed in the complete specification is 
not the same as that contained in the provisional specification,

Government department; 
(p) that, in the case of a patent bearing a date within any war 
period as defined by section 33 (3), the invention was secretly 
worked prior to that date by a Government department or the

the applicant for the patent directly or indirectly to a Government 
department; 
(q) that, in the case of inventions relating to substances 
prepared or produced by chemical processes or intended for 
food or medicine, the specification includes claims which under 
section 44 cannot lawfully be made; or 
upon any other ground upon which a patent might, immediately 
before the 6th December, 1902, have been repealed by scire facias: 
Provided that this subsection shall have effect, as respects the 
ground of revocation specified in paragraph (e) thereof, subject to 
section 19 (1), section 34 (12), section 45 and section 50. 
(3) Every ground on which a patent may be revoked shall be

patent. 
(4) A petition for revocation of a patent may be presented­

him; or 
(b) by any person alleging-
(i) that the patent was obtained in fraud of his rights, or

30. (1) Any person who would have been entitled to oppose the 
grant of a patent or is the successor in interest of a person who was

patent. 
(3) A patentee may at ailY time by giving notice in the pre­
scribed manner to the Registrar offer to surrender his patent, and the

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; IP /NI lIG UY 1111

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 sucr. IPINIlIGUY/IIl

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 t.1Unk 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 suc1Y 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; 
(b) 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 i...'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), (c) or (d); 
(b) a period of not less than two years has elapsed between 
the date of that order and the date of the application; and 
Cc) the Registra: 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), IPIN/lIGUYIII 1 
Page 30 
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.

section,must set out fully the nature of the applicant's interest and the 
facts upon which the applicant bases his case and the relief which he 
seeks. 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 01: 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 ef 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 declarants 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 Imeer 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 
(a) if th~ parties interested consent; or 
(b) if the proc:;;dings require any prolonged e~,-a:mination of 
cccuments or any scientific er 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

the State as it has against a citizen: 
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

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: 
Provided further that, where an invention which is the subject of 
any patent has, before the d;;te of the patent, been duly recorded in a
