BE it enacted by the King's most Excellent Majesty, by and with the advice and consent of the Lords Spiritual and Temporal, and Commons, in this present Parliament assembled, and by the authority of the same, as follows:-

1.-(1) An application for a patent for an invention may be made by any of the following persons, that is to say:-

(b) by any person being the assignee of the person claiming to be the true and first inventor in respect of the right to make such an application;

(2) Without prejudice to the foregoing provisions of this section, an application for a patent for an invention in respect of which protection has been applied for in a convention country may be made by the person by whom the application for protection was made or by the assignee of that person:

Provided that no application shall be made by virtue of this subsection after the expiration of twelve months from the date of the application for protection in a convention country or, where more than one such application for protection has been made, from the date of the first application.

(3) An application for a patent may be made under subsection (1) or subsection (2) of this section by the personal representative of any deceased person who, immediately before his death, was entitled to make such an application.

(4) An application for a patent made by virtue of subsection (2) of this section is in this Act referred to as a convention application.

2.-(1) Every application for a patent shall be made in the prescribed form and shall be filed at the Patent Office in the prescribed manner.

(2) If the application (not being a convention application) is made by virtue of an assignment of the right to apply for a patent for the invention, there shall be furnished with the application or within such period as may be prescribed after the filing of the application a declaration, signed by the person claiming to be the true and first inventor or his personal representative, stating that he assents to the making of the application.

(3) Every application (other than a convention application) shall state that the applicant is in possession of the invention and shall name the person claiming to be the true and first inventor; and where the person so claiming is not the applicant or one of the applicants, the application shall contain a declaration that the applicant believes him to be the true and first inventor

(4) Every convention application shall specify the date on which and the convention country in which the application for protection, or the first such application, was made, and shall state that no application for protection in respect of the invention had been made in a convention country before that date by the applicant or any person from whom he derives title.

(5) Where applications for protection have been made in one or more convention countries in respect of two or more inventions which are cognate or of which one is a modification of another, a single convention application may, subject to the provisions of section four of this Act, be made in respect of those inventions at any time within twelve months from the date of the earliest of the said applications for protection:

Provided that the fee payable on the making of any such application shall be the same as if separate applications had been made in respect of each of the said inventions, and the requirements of the last foregoing subsection shall in the case of any such application apply separately to the applications for protection in respect of each of the said inventions.

3.-(1) Every application for a patent (other than a convention application) shall be accompanied by either a complete specification or a provisional specification; and every convention application shall be accompanied by a complete specification.

(2) Where an application for a patent is accompanied by a provisional specification, a complete specification shall be filed within twelve months from the date of filing of the application and if the complete specification is not so filed the application shall be deemed to be abandoned:

Provided that the complete specification may be filed at any time after twelve months but within fifteen months from the date aforesaid if a request to that effect is made to the comptroller and the prescribed fee paid on or before the date on which the specification is filed.

(3) Where two or more applications accompanied by provisional specifications have been filed in respect of inventions which are cognate or of which one is a modification of another, a single complete specification may, subject to the provisions of this and the next following section, be filed in pursuance of those applications, or, if more than one complete specification has been filed, may with the leave of the comptroller be proceeded with in respect of those applications.

(4) Where an application for a patent (not being a convention application) is accompanied by a specification purporting to be a complete specification, the comptroller may, if the applicant so requests at any time before the acceptance of the specification, direct that it shall be treated for the purposes of this Act as a provisional specification, and proceed with the application accordingly.

(5) Where a complete specification has been filed in pursuance of an application for a patent accompanied by a provisional specification or by a specification treated by virtue of a direction under the last foregoing subsection as a provisional specification, the comptroller may. if the applicant so requests at any time before the acceptance of the complete specification, cancel the provisional specification and post-date the application to the date of filing of the complete specification.

4.-(1) Every specification, whether complete or provisional, shall describe the invention, and shall begin with a title indicating the subject to which the invention relates.

(2) Subject to any rules made by the Board of Trade under this Act, drawings may, and shall if the comptroller so requires, be supplied for the purposes of any specification, whether complete or provisional; and any drawings so supplied shall, unless the comptroller otherwise directs, be deemed to form part of the specification, and references in this Act to a specification shall be construed accordingly.

(a) shall particularly describe the invention and the method by which it is to be performed;

(b) shall disclose the best method of performing the invention which is known to the applicant and for which he is entitled to claim protection; and

(4) The claim or claims of a complete specification must relate to a single invention, must be clear and succinct, and must be fairly based on the matter disclosed in the specification.

(5) Rules made by the Board of Trade under this Act may require that in such cases as may be prescribed by the rules, a declaration as to the inventorship of the invention, in such form as may be so prescribed, shall be furnished with the complete specification or within such period as may be so prescribed after the filing of that specification.

(6) Subject to the foregoing provisions of this section, a complete specification filed after a provisional specification, or filed with a convention application, may include claims in respect of developments of or additions to the invention which was described in the provisional specification or, as the case may be, the invention in respect of which the application for protection was made in a convention country, being developments or additions in respect of which the applicant would be entitled under the provisions of section one of this Act to make a separate application for a patent.

(7) Where a complete specification claims a new substance, the claim shall be construed as not extending to that substance when found in nature.

5.-(1) Every claim of a complete specification shall have effect from the date prescribed by this section in relation to that claim (in this Act referred to as the priority date); and a patent shall not be invalidated by reason only of the publication or use of the invention, so far as claimed in any claim of the complete specification, on or after the priority date of that claim, or by the grant of another patent upon a specification claiming the same invention in a claim of the same or later priority date.

(2) Where the complete specification is filed in pursuance of a single application accompanied by a provisional specification or by a specification which is treated by virtue of a direction under subsection (4) of section three of this Act as a provisional specification, and the claim is fairly based on the matter disclosed in that specification, the priority date of that claim shall be the date of filing of the application.

(3) Where the complete specification is filed or proceeded with in pursuance of two or more applications accompanied by such specifications as are mentioned in the last foregoing subsection, and the claim is fairly based on the matter disclosed in one of those specifications, the priority date of that claim shall be the date of filing of the application accompanied by that specification.

(4) Where the complete specification is filed in pursuance of a convention application and the claim is fairly based on the matter disclosed in the application for protection in a convention country or, where the convention application is founded upon more than one such application for protection, in one of those applications, the priority date of that claim shall be the date of the relevant application for protection.

(5) Where, under the foregoing provisions of this section, any claim of a complete specification would, but for this, provision, have two or more priority dates, the priority date of that claim shall be the earlier or earliest of those dates.

(6) In any case to which subsections (2) to (5) of this section do not apply, the priority date of a claim shall be the date of filing of the complete specification.

6.-(1) When the complete specification has been filed in respect of an application for a patent, the application and specification or specifications shall be referred by the comptroller to an examiner.

(2) If the examiner reports that the application or any specification filed in pursuance thereof does not comply with the requirements of this Act or of any rules made by the Board of Trade thereunder, or that there is lawful ground of objection to the grant of a patent in pursuance of the application, the comptroller may either-

(b) require the application or any such specification as aforesaid to be amended before he proceeds with the application.

(3) At any time after an application has been filed under this Act and before acceptance of the complete specification, the comptroller may, at the request of the applicant and upon payment of the prescribed fee, direct that the application shall be post-dated to such date as may be specified in the request:

(a) no application shall be post-dated under this subsection to a date later than six months from the date on which it was actually made or would, but for this subsection, be deemed to have been made; and

(b) a convention application shall not be post-dated under this subsection to a date later than the last date on which, under the foregoing provisions of this Act, the application could have been made.

(4) Where an application or specification filed under this Act is amended before acceptance of the complete specification, the comptroller may direct that the application or specification shall be post-dated to the date on which it is amended or, if it has been returned to the applicant, to the date on which it is refiled.

(5) Rules made by the Board of Trade under this Act may make provision for securing that where, at any time after an application or specification has been filed under this Act and before acceptance of the complete specification, a fresh application or specification is filed in respect of any part of the subject matter of the first-mentioned application or specification, the comptroller may direct that the fresh application or specification shall be ante-dated to a date not earlier than the date of filing of the first-mentioned application or specification.

(6) An appeal shall lie from any decision of the comptroller under subsection (2) or subsection (4) of this section.

7.-(1) Subject to the provisions of the last foregoing section, the examiner to whom an application for a patent is referred under this Act shall make investigation for the purpose of ascertaining whether the invention, so far as claimed in any claim of the complete specification, has been published before the date of filing of the applicant's complete specification in any specification filed in pursuance of an application for a patent made in the United Kingdom and dated within fifty years next before that date.

(2) The examiner shall, in addition, make such investigation as the comptroller may direct for the purpose of ascertaining whether the invention, so far as claimed in any claim of the complete specification, has been published in the United Kingdom before the date of filing of the applicant's complete specification in any other document (not being a document of any class described in subsection (1) of section fifty of this Act).

(3) If it appears to the comptroller that the invention, so far as claimed in any claim of the complete specification, has been published as aforesaid, he may refuse to accept the specification unless the applicant either-

(a) shows to the satisfaction of the comptroller that the priority date of the claim of his complete specification is not later than the date on which the relevant document was published; or

(4) An appeal shall lie from any decision of the comptroller under this section.

(8).-(1) In addition to the investigation required by the last foregoing section, the examiner shall make investigation for the purpose of ascertaining whether the invention, so far as claimed in any claim of the complete specification, is claimed in any claim of any other complete specification published on or after the date of filing of the applicant's complete specification, being a specification filed-

(a) in pursuance of an application for a patent made in the United Kingdom and dated before that date; or

(b) in pursuance of a convention application founded upon an application for protection made in a convention country before that date.

(2) If it appears to the comptroller that the said invention is claimed in a claim of any such other specification as aforesaid, he may, subject to the provisions of this section, direct that a reference to that other specification shall be inserted by way of notice to the public in the applicant's complete specification unless within such time as may be prescribed either-

(a) the applicant shows to the satisfaction of the comptroller that the priority date of his claim is not later than the priority date of the claim of the said other specification; or

(b) the complete specification is amended to the satisfaction of the comptroller.

(3) If in consequence of the investigation under section seven of this Act or otherwise it appears to the comptroller-

(a) that the invention, so far as claimed in any claim of the applicant's complete specification, has been claimed in any such specification as is mentioned in subsection (1) of that section; and

(b) that the other specification was published on or after the priority date of the applicant's claim,

then unless it has been shown to the satisfaction of the comptroller under that section that the priority date of the applicant's claim is not later than the priority date of the claim of that other specification, the provisions of subsection (2) of this section shall apply as they apply in relation to a specification published on or after the date of filing of the applicant's complete specification.

(4) The powers of the comptroller under this section to direct the insertion of a reference to another specification may be exercised either before or after a patent has been granted for the invention claimed in that other specification, but any direction given before the grant of such a patent shall be of no effect unless and until such a patent is granted.

(5) An appeal shall lie from any direction of the comptroller under this section.

9.-(1) If, in consequence of the investigations required by in case of the foregoing provisions of this Act or of proceedings under potential section fourteen or section thirty-three of this Act, it appears to the comptroller that an invention in respect of which application for a patent has been made cannot be performed without substantial risk of infringement of a claim of any other patent, he may direct that a reference to that other patent shall be inserted in the applicant's complete specification by way of notice to the public unless within such time as may be prescribed either-

(a) the applicant shows to the satisfaction of the comptroller that there are reasonable grounds for contesting the validity of the said claim of the other patent; or

(b) the complete specification is amended to the satisfaction of the comptroller.

(2) Where, after a reference to another patent has been inserted in a complete specification in pursuance of a direction under the foregoing subsection,-

(b) specification of that other patent is amended by the deletion of the relevant claim; or

(c) it is found, in proceedings before the court of the comptroller, that the relevant claim of that other patent is invalid or is not infringed by any working of the applicant's invention,

the comptroller may, on the application of the applicant, delete the reference to that other patent.

(3) An appeal shall lie from any decision or direction of the comptroller under this section.

10.-(1) If it appears to the comptroller in the case of any application for a patent-

(a) that it is frivolous on the ground that it claims as an invention anything obviously contrary to well-established natural laws; or

(b) that the use of the invention in respect of which the application is made would be contrary to law or morality; or

(c) that it claims as an invention a substance capable of being used as food or medicine which is a mixture of known ingredients possessing only the aggregate of the known properties of the ingredients, or that it claims as an invention a process producing such a substance by mere admixture,

(2) If it appears to the comptroller that any invention in respect of which an application for a patent is made might be used in any manner contrary to law, he may refuse the application unless the specification is amended by the insertion of such disclaimer in respect of that use of the invention, or such other reference to the illegality thereof, as the comptroller thinks fit.

(3) An appeal shall lie from any decision of the comptroller under this section.

11.-(1) The powers of the comptroller under section eight or section nine of this Act may be exercised either before of after the complete specification has been accepted or a patent granted to the applicant, and references in those sections to the applicant shall accordingly be construed as including references to the patentee.

(2) Where a complete specification is amended under the foregoing provisions of this Act before it has been accepted, the amended specification shall be examined and investigated in like manner as the original specification.

(3) The examination and investigation required by the foregoing provisions of this Act shall not be deemed to warrant the validity of any patent, and no liability shall be incurred by the Board of Trade or any officer thereof by reason of or in connection with any such examination or investigation or any report or other proceedings consequence thereon.

12.-(1) An application for a patent shall be void unless within twelve months from the date of filing of the complete specification, or within such longer period as may be allowed under the following provisions of this section, the applicant has complied with all requirements imposed on him by or under this Act, whether in connection with the complete specification or otherwise in relation to the application; and where the application or any specification or, in the case of a convention application, any document filed as part of the application, has been returned to the applicant by the comptroller in the course of the proceedings, the applicant shall not be deemed to have complied with the said requirements unless and until he has refiled it.

(2) The period allowed by subsection (1) of this section shall be extended to such period, not exceeding fifteen months form the date of filing of the complete specification, as may be specified in a notice given by the applicant to the comptroller, if the notice is given and the prescribed fee paid before the expiration of the period so specified.

(3) If at the expiration of the period allowed under the foregoing provisions of this section an appeal of the Appeal Tribunal is pending under any of the provisions of this Act in respect of the application (or, in the case of an application for a patent of addition, either in respect of that application or in respect of the application for the patent for the main invention) or the time within which such an appeal could be bought in accordance with the rules of that Tribunal (apart from any future extension of time thereunder) has not expired, then-

(a) where such an appeal is pending, or is brought within the time aforesaid or before the expiration of any extension of that time granted (in the case of a first extension) on an application made within that time or (in the case of a subsequent extension) on an application made before the expiration of the last previous extension, the said period shall be extended until such dates as the Appeal Tribunal may determine;

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

13.-(1) Subject to the provisions of the last foregoing section, the complete specification filed in pursuance of an application for a patent may be accepted by the comptroller at any time after the applicant has complied with the requirements mentioned in subsection (1) of that section, and if not so accepted within the period allowed under that section for compliance with those requirements, shall be accepted as soon as may be thereafter:

Provided that the applicant may give notice to the comptroller requesting him to postpone acceptance until such date, not being later than fifteen months from the date of filing of the complete specification, as may be specified in the notice; and if such notice is given and, where the notice requests a postponement to a date later than twelve months from the date aforesaid, the prescribed fee is paid, the comptroller may postpone acceptance accordingly.

(2) On the acceptance of a complete specification the comptroller shall give notice to the applicant, and shall advertise in the Journal the fact that the specification has been accepted and the date on which the application and the specification or specifications filed in pursuance thereof will be open to public inspection.

(3) Any reference in this Act to the date of the publication of a complete specification shall be construed as a reference to the date advertised as aforesaid.

(4) After the date of the publication of a complete specification and until the sealing of a patent in respect thereof, the applicant shall have the like privileges and rights as if a patent for the invention had been sealed on the date of the publication of the complete specification:

Provided that an applicant shall not be entitled to institute any proceedings for infringement until the patent has been sealed.

14.-(1) At any time within three months from the date of the publication of a complete specification under this Act, any person interested may give notice to the comptroller of opposition to the grant of the patent on any of the following grounds:-

(a) that the applicant for the patent, or the person described in the application as the true and first inventor, obtained the invention or any part thereof from him, or from a person of whom he is the personal representative;

(b) that the invention, so far as claimed in any claim of the complete specification, has been published in the United Kingdom, before the priority date of the claim-

(i) in any specification filed in pursuance of an application for a patent made in the United Kingdom and dated within fifty years next before the date of filing of the applicant's complete specification;

(ii) in any other document (not being a document of any class described in subsection (1) of section fifty of this Act);

(c) that the invention, so far as claimed in any claim of the complete specification, is claimed in any claim of a complete specification published on or after the priority date of the applicant's claim and filed in pursuance of an application for a patent in the United Kingdom, being a claim of which the priority date is earlier than that of the applicant's claim;

(d) that the invention, so far as claimed in any claim of the complete specification, was used in the United Kingdom before the priority date of that claim;

(e) that the invention, so far as claimed in any claim of the complete specification, is obvious and clearly does not involve any inventive step having regard to matter published as mentioned in paragraph (b) of this subsection, or having regard to what was used in the United Kingdom before the priority date of the applicant's claim;

(f) that the subject of any claim of the complete specification is not an invention within the meaning of this Act;

(g) that the complete specification does not sufficiently and fairly described the invention or the method by which it is to be performed;

(h) that, in the case of a convention application, the application was not made within twelve months from the date of the first application for protection for the invention made in a convention country by the applicant or a person form whom he derives title;

(2) Where any such notice is given, the comptroller shall give notice of the opposition to the applicant, and shall give to the applicant and the opponent an opportunity to be heard before he decides on the case.

(3) The grant of a patent shall not be refused on the ground specified in paragraph (c) of subsection (1) of this section if no patent has been granted in pursuance of the application mentioned in that paragraph; and for the purposes of paragraph (d) or paragraph (e) of the said subsection (1) no account shall be taken of any secret use.

(4) An appeal shall lie from any decision of the comptroller under this section.

15.-(1) If at any time after the acceptance of the complete specification filed in pursuance of an application for a patent and before the grant of a patent thereon it comes to the notice of the comptroller, otherwise than in consequence of proceedings in opposition to the grant under the last foregoing section, that the invention, so far as claimed in any claim of the complete specification, has been published in the United Kingdom before the priority date of the claim-

(a) in any specification filed in pursuance of an application for a patent made in the United Kingdom and dated within fifty years next before the date of filing of the applicant’s complete specification; or

(b) in any other document (not being a document of any class described in subsection (1) of section fifty of this Act),

the comptroller may refuse to grant the patent unless within such time as may be prescribed the complete specification is amended to his satisfaction.

(2) An appeal shall lie from any decision of the comptroller under this section.

16.-(1) If the comptroller is satisfied, upon a request or claim made in accordance with the provisions of this section-

(a) that the person in respect of or by whom the request or such in patent claim is made is the inventor of an invention in respect of which application for a patent has been made, or of a substantial part of that invention; and

(b) that the application for the patent is a direct consequence of his being the inventor,

the comptroller shall, subject to the provisions of this section, cause him to be mentioned as inventor in any patent granted in pursuance of the application, in the complete specification, and in the register of patents:

Provided that the mention of any person as inventor under this section shall not confer or derogate from any rights under the patent.

(2) For the purposes of this section the actual deviser of an invention or a part of an invention shall be deemed to be the inventor, notwithstanding that any other person is for any of, the other purposes of this Act treated as the true and first inventor; and no person shall be deemed to be the inventor of an invention or a part of an invention by reason only that it was imported by him into the United Kingdom.

(3) A request that any person shall be mentioned as aforesaid may be made in the prescribed manner by the applicant for the patent or (where the person alleged to be the inventor is not the applicant or one of the applicants) by the applicant and that person.

(4) If any person (other than a person in respect of whom a request in relation to the application in question has been made under the last foregoing subsection) decides to be mentioned as aforesaid, he may make a claim in the prescribed manner in that behalf.

(5) A request or claim under the foregoing provisions of this section must be made not later than two months after the date of the publication of the complete specification, or within such further period (not exceeding one month) as the comptroller may, on an application made to him in that behalf before the expiration of the said period of two months and subject to payment of the prescribed fee, allow.

(6) No request or claim under the foregoing provisions of this section shall be entertained if it appears to the comptroller that the request or claim is based upon facts which, if proved in the case of an opposition under the provisions of paragraph (a) of subsection (1) of section fourteen of this Act by the person in respect of or by whom the request or claim is made, would have entitled him to relief under that section.

(7) Subject to the provisions of the last foregoing subsection, where a claim is made under subsection (4) of this section, the comptroller shall give notice of the claim to every applicant for the patent (not being the claimant) and to any other person whom the comptroller may consider to be interested; and before deciding upon any request or claim made under subsection (3) or subsection (4) of this section, the comptroller shall, if required, hear the person in respect of or by whom the request or claim is made, and, in the case of a claim under the said subsection (4), any person to whom notice of the claim has been given as aforesaid.

(8) Where any person has been mentioned as inventor in pursuance of this section, any other person who alleges that he ought not to have been so mentioned may at any time apply to the comptroller for a certificate to that effect, and the comptroller may, after hearing, if required, any person whom be may consider to be interested, issue such a certificate, and if he does so, he shall rectify the specification and the register accordingly.

(9) An appeal shall lie from any decision of the comptroller under this section.

17.-(1) If the comptroller is satisfied, on a claim made in the prescribed manner at any time before a patent has been granted, that by virtue of any assignment or agreement made by the applicant or one of the applicants for the patent, or by operation of law, the claimant would, if the patent were then granted, be entitled thereto or to the interest of the applicant therein, or to an undivided share of the patent or of that interest, the comptroller may, subject to the provisions of this section, direct that the application shall proceed in the name of the claimant or in the names of the claimant and the applicant or the other joint applicant or applicants, according as the case may require.

(2) No such direction as aforesaid shall be given by virtue of any assignment or agreement made by one of two or more joint applicants for a patent except with the consent of the other joint applicant or applicants.

(3) No such direction as aforesaid shall be, given by virtue of any assignment or agreement for the assignment of the benefit of an invention unless either-

(3) The licensee under any licence granted by virtue of the endorsement of a patent under this section shall (unless, in the case of a licence the terms of which are settled by agreement, the licence otherwise expressly provides) be entitled to call upon the patent to take proceedings to prevent any 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 if he were patentee, making the patentee a defendant:

Provided that a patentee so added as defendant shall not be liable for any costs unless he enters an appearance and takes part in the proceedings.

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

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

(6) All endorsements of patents under this section shall be entered in the register of patents and shall be published in the Journal and in such other manner as the comptroller thinks desirable for bringing the endorsement to the notice of manufacturers.

36.-(1) At any time after a patent has been endorsed under the last foregoing section, the patentee may apply to the comptroller for cancellation of the endorsement; and where such an application is made and the balance paid of all renewal fees which would have been payable if the patent had not been endorsed, the comptroller may, if satisfied that there is no existing licence under the patent or that all licensees under the patent consent to the application, cancel the endorsement accordingly.

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

(3) Where the comptroller is satisfied, on application made under the last foregoing subsection, that the patentee is and was precluded as aforesaid, he shall cancel the endorsement; and thereupon the patentee shall be liable to pay, within such period as may be prescribed, a sum equal to the balance of all renewal fees which would have been payable if the patent had not been endorsed, and if that sum is not paid within that period the patent shall cease to have effect at the expiration of that period.

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

(5) The comptroller shall advertise in the prescribed manner any application made to him under this section; and within the prescribed period after such advertisement-

(8) An appeal shall lie from any decision of the comptroller under this section.

37.-(1) At any time after the expiration of three years from the date of the sealing of a patent, any person interested may apply to the comptroller upon any one or more of the grounds specified in the next following subsection for a licence under the patent or for the endorsement of the patent with the words “licences of right.”

(2) The grounds upon which application may be made for an order under this section are as follows, that is to say:-

(a) that the patented invention, being capable of being commercially worked in the United Kingdom, is not being commercially worked therein or is not being so worked to the fullest extent that reasonably practicable ;

(b) that a demand for the patented article in the United Kingdom is not being met on reasonable terms, or is being met to a substantial extent by importation;

(c) that the commercial working of the invention in the United Kingdom is being prevented or hindered by the importation of the patented article;

(d) that by reason of the refusal of the patentee to grant a licence or licences on reasonable terms-

(i) a market for the export of the patented article manufactured in the United Kingdom is not being supplied; or

(ii) the working or efficient working in the United Kingdom of any other patented invention which snakes a substantial contribution to the art is prevented or hindered; or

(iii) the establishment or development of commercial or industrial activities in the United Kingdom is unfairly prejudiced;

(e) that by reason of conditions imposed by the patentee upon the grant of licences under the patent or upon the purchase, hire or use of the patented article or process, the manufacture, use or sale of materials not protected by the patent, or the establishment or development of commercial or industrial activities in the United Kingdom is unfairly prejudiced.

(3) Subject as hereinafter provided, the comptroller may, if satisfied that any of the grounds aforesaid are established, make an order in accordance with the application; and where the order is for the grant of a licence, it may require the licence to be granted upon such terms as the comptroller thinks fit:

(a) where the application is made on the ground that the patented invention is not being commercially worked in the United Kingdom or is not being worked to the fullest extent that is reasonably practicable, and it appears to the comptroller that the time which has elapsed since the sealing of the patent has for any reason been insufficient to enable it to be so worked, he may by order adjourn the application for such period as will in his opinion give sufficient time for the invention to be so worked ;

(b) an order shall not be made under this section for the endorsement of a patent on the ground that a market for the export of the patented article is not being supplied, and any licence granted under this section on that ground shall contain such provisions as appear to the comptroller to be expedient for restricting the countries in which the patented article may be sold or used by the licensee;

(c) no order shall be made under this section in respect of a patent on the ground that the working or efficient working in the United Kingdom of another patented invention is prevented or hindered unless the comptroller is satisfied that the patentee in respect of that other invention is able and willing to grant to the patentee and his licensees a licence in respect of that other invention on reasonable terms.

(4) An application under this section may be made by any person notwithstanding that he is already the holder of a licence under the patent; and no person shall be estopped from alleging any of the matters specified in subsection (2) of this section by reason of any admission made by him, whether in such a licence or otherwise, or by reason of his having accepted such a licence.

(5) In this section the expression "patented article" includes any article made by a patented process.

38.-(l) Where the comptroller is satisfied, on application made under the last foregoing section, that the manufacture, use or sale of materials not protected by the patent is unfairly prejudiced by reason of conditions imposed by the patentee upon the grant of licences under the patent, or upon the purchase, hire or use of the patented article or process, he may, subject to the provisions of that section, order the grant of licences under the patent to such customers of the applicant as he thinks fit as well as to the applicant.

(2) Where an application under the last foregoing section is made by a person being the holder of a licence under the patent, the comptroller may, if he makes an order for the grant of a licence to the applicant, order the existing licence to be cancelled, or may, if he thinks fit, instead of making an order for the grant of a licence to the applicant, order the existing licence to be amended.

(3) Where on an application under the last foregoing section the comptroller orders the grant of a licence, he may direct that the licence shall operate-

(a) to deprive the patentee of any right which he may have as patentee to make, use, exercise or vend the invention or to grant licences under the patent;

(4) Subsection (3) of section thirty-five of this Act shall apply to any licence granted in pursuance of an order under the last foregoing section as it applies to a licence granted by virtue of the said section thirty-five.

39.-(1) The powers of the comptroller upon an application under section thirty seven of this Act shall be exercised with a view to securing the following general purposes, that is to say:-

(b) that the inventor or other person beneficially entitled to a patent shall receive reasonable remuneration having regard to the nature of the invention;

(c) that the interests of any person for the time being working or developing an invention in the United Kingdom under the protection of a patent shall not be unfairly prejudiced.

(2) Subject to the foregoing subsection, the comptroller shall, in determining whether to make an order in pursuance of any such application, take account of the following matters, that is to say:-

(a) the nature of the invention, the time which has elapsed since the sealing of the patent and the measures already taken by the patentee or any licensee to make full use of the invention ;

(b) the ability of any person to whom a licence would be granted under the order to work the invention to the public advantage; and

(c) the risks to be undertaken by that person in providing capital and working the invention if the application is granted;

but shall not be required to take account of matters subsequent to the making of the application.

40 -(1) At any time after the expiration of three years from the date of the sealing of a patent, any Government department may apply to the comptroller upon any one or more of the grounds specified in section thirty-seven of this Act for the endorsement of the patent with the words “licences of right” a licence under the patent; and the comptroller may, if satisfied that any of those grounds are established, make an order in application with the application.

(2) Subsections (3) and (5) of section thirty-seven of this Act and sections thirty-eight and thirty-nine of this Act shall, so far as applicable, apply in relation to an application and an order under the last foregoing subsection as they apply in relation to an application and an order under the said section thirty-seven.

(3) Where according to a report of the Monopolies and Restrictive Practices Commission as laid before Parliament under section nine of the Monopolies and Restrictive Practices
(Inquiry and Control) Act, 1948, conditions to which that Act applies prevail in respect of the supply of goods of any description which consist of or include patented articles, or in respect
of exports of such goods, or in respect of the application to goods of any description of any process which consists of or includes a patented process, and, not earlier than three months from the date on which the report was laid before the Commons House of Parliament, a resolution has been passed by that House declaring that those conditions or any things which, according to the report as laid before Parliament, are done by the parties concerned, as a result of or for the purpose of preserving those conditions, operate or may be expected to operate against the public interest, a competent authority within the meaning of the said Act of 1948 may apply to the comptroller for an order under the next following subsection in respect of the patent.

(4) If upon an application under the last foregoing subsection it appears to the comptroller that the matters which, according to the resolution mentioned in that subsection, operate or may be expected to operate against the public interest include-

(a) any conditions in a licence or licences granted by the patentee under the patent restricting the use of the invention by the licensee or the right of the patentee to grant other licences under the patent; or

(b) a refusal by the patentee to grant licences under the patent on reasonable terms,

he may by order cancel or modify any such condition as aforesaid or may, if he thinks fit, instead of making such an order or in addition to making such an order, order the patent to be endorsed with the words "licences of right ".

41.-(1) Without prejudice to the foregoing provisions of this Act, where a patent is in force in respect of-

(a) a substance capable of being used as food or medicine or in the production of food or medicine; or

(b) that the purposes for which an order may be made in pursuance of an application under the said section thirty-seven could not be achieved by the making of any such order as is authorised to be made in pursuance of such an application,

(2) An order for the revocation of a patent under this section may be made so as to take effect either unconditionally or in the event of failure to comply, within such reasonable period as may be specified in the order, with such conditions as may be imposed by the order with a view to achieving the purposes aforesaid; and the comptroller may, on reasonable cause shown in any case, by subsequent order extend any period so specified.

43.-(1) Every application under sections thirty-seven to forty-two of this Act shall specify the nature of the order sought by the applicant and shall contain a statement (to be verified in such manner as may be prescribed) setting out the nature of the applicant's interest (if any) and the facts upon which the application is based.

(2) Where the comptroller is satisfied, upon consideration of any such application, that a prima facie case has been made out for the making of an order, he shall direct the applicant to serve copies of the application upon the patentee and any other persons appearing from the register of patents to be interested in the patent in respect of which the application is made, and shall advertise the application in the Journal.

(3) The patentee or any other person desiring to oppose the application may, within such time as may be prescribed or within such further time as the comptroller may on application (made either before or after the expiration of the prescribed time) allow, give to the comptroller notice of opposition.

title learned of the publication before the date of the application for the patent or (in the case of a convention application) the date of the application for protection in a convention country, that the application or the application in a convention country, as the case may be, was made as soon as reasonably practicable thereafter:

Provided that this subsection shall not apply if the invention was before the priority date of the claim commercially worked in the United Kingdom, otherwise than for the purpose of reasonable trial, either by the patentee or applicant for the patent or by any other person from whom he derives title or by any other person with the consent of the patentee or applicant for the patent or any person from whom he derives title.

(3) Where a complete specification is filed in pursuance of an application for a patent made by a person being the true and first inventor or deriving title from him, an invention claimed in that specification shall not be deemed to have been anticipated by reason only of any other application for a patent in respect of the same invention, made in contravention of the rights of that person, or by reason only that after the date of filing of that other application the invention was used or published, without the consent of that person, by the applicant in respect of that other application, or by any other person in consequence of any disclosure of the invention by that applicant.

(3) As a condition of relief under subsection (1) or subsection (2) of this section the court may direct that the specification shall be amended to its satisfaction upon an application made for that purpose under section thirty of this Act, and such an application may be made accordingly whether or not all other issues in the proceedings have been determined.
