9. (1) Any person may, on payment of the prescribed fee, at any time within four months from the date of the advertisement of the acceptance of an application, give notice at the Department of Patents, Designs and Trade Marks of opposition to the grant of the patent on any of the following grounds, namely:- (a) that the applicant obtained the invention from him, or from a person of whom he is the legal representative or assign; or (b) that the invention has been claimed in any specification filed in Bangladesh which is or will be of prior date to the patent, the grant of which is opposed; or (c) that the nature of the invention or the manner in which it is to be performed is not sufficiently or fairly described and ascertained in the specifications; or (d) that the invention has been publicly used in any part of Bangladesh or has been made publicly known in any part of Bangladesh; or (e) that the complete specification describes or claims an invention other than that described in the provisional specification, and that such other invention either froms the subject of an application made by the opponent for a patent which if granted would bear a date in the interval between the date of the application and the leaving of the complete specification, or has been made available to the public by publication in any document published in Bangladesh in that interval; but on no other ground.(2) Where such notice is given, the Registrar shall give notice of the opposition to the applicant, and shall, on the expiration of those four months, after hearing the applicant and the opponent, if desirous of being heard, decide on the case. (3) The decision of the Registrar shall be subject to appeal to the Government.

10. (1) If there is no opposition, or, in case of opposition, if the determination is in favour of the grant of a patent, a patent shall, on payment of the prescribed fee, be granted, subject to such conditions (if any) as the Government thinks expedient, to the applicant, or in the case of a joint application to the applicants jointly, and the Registrar shall cause the patent to be sealed with the seal of the Department of Patents, Designs and Trade Marks. (1A) Notwithstanding anything contained in sub-section (1), where- (a) an applicant has agreed in writing that on the grant to him of a patent he will assign it to another party or to a joint applicant and refuses to proceed with the application, or (b) disputes arise between joint applicants as to proceeding with an application, the Registrar, if he is satisfied of the existence of such agreement or, in any other case, that any joint applicant or applicants ought to be allowed to proceed alone, may direct that such other party or joint applicant or applicants may proceed with the application accordingly and may grant a patent to him or them, as the case may be: Provided that- (i) the Controller shall not give any such direction until every party interested has had an opportunity of being heard by him, and (ii) an appeal from any such direction shall lie to the Government. (2) A patent shall be sealed as soon as may be, and not after the expiration of twenty-four months from the date of application: Provided that,- (a) where the Registrar has allowed an extension of the time within which an application may be accepted a further extension of four months after the said, twenty-four months shall be allowed for the sealing of the patent; (b) where the sealing is delayed by an appeal to the Government, or by opposition to the grant of the patent, or by any proceedings taken for obtaining a direction of the Registrar under the provisions of sub-section (1A), or by reason of the Registrar, in exercise of the powers given to him by ⁸[any other law for the time being in force], having omitted to do or delayed the doing of anything relating to the application the patent may be sealed at such time as 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 which would otherwise be allowed for sealing the patent, the patent may be sealed at any time within twelve months after the date of his death or at such later time as the Registrar may think fit; (d) where for any reason a patent cannot be sealed within the period allowed by any of the foregoing provisions of this section that period may on payment of the prescribed fee and on compliance with the prescribed conditions be extended to the extent applied for but not exceeding three months.

11. Except as otherwise expressly provided by this Act, a patent shall be dated and sealed as of the date of the application:Provided that no proceedings shall be taken in respect of an infringement committed before the advertisement of the acceptance of the application.

12. (1) A patent sealed with the seal of the Department of Patents, Designs and Trade Marks shall, subject to the other provisions of this Act, confer on the patentee the exclusive privilege of making, selling and using the invention throughout Bangladesh and of authorizing others so to do.(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 a suit or other proceeding to take any objection to a patent on the ground that it has been granted for more than one invention.

13. (1) A patent granted to the true and first inventor or his legal representative or assign shall not be invalidated by an application in fraud of him, or by protection obtained thereon or by any use or publication of the invention subsequent to that fraudulent application during the period of protection.(2) Where a patent has been revoked by the High Court Division on the ground that it has been obtained in fraud of the true and first inventor, or where the grant of a patent has been refused by the Registrar under section 9 on the ground stated in clause (a) of sub-section (1) of that section, the Registrar may, on the application of the true inventor or his legal representative or assign made in accordance with the provisions of this Act, grant to him a patent for the whole or any part of the invention, and the patent so granted shall bear the same date as the patent so revoked or, in the case of a patent the grant of which has been refused, the same date as would have been borne by the patent if it had been granted:Provided that no suit shall be brought for any infringement of the patent so granted committed before the actual date when such patent was granted.

⁹[13A. (1) Where the same applicant has put in two or more provisional specifications for inventions which are cognate or modifications 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 allow 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 determining 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.]

14. (1) The term limited in every patent for the duration thereof shall, save as otherwise expressly provided by this Act, be sixteen years from its date. (1A) and (1B) [Omitted by section 3 and 2nd Schedule of the Bangladesh Laws (Revision And Declaration) Act, 1973 (Act No. VIII of 1973).] (2) A patent shall, notwithstanding anything therein or in this Act, cease if the patentee fails to pay the prescribed fees within the prescribed times: Provided that where the patentee, before, or within three months after, the expiration of the time for payment, applies to the Registrar for an extension of time, the patent shall, on payment of such additional fee as may be prescribed, be continued or revived, as the case may be, for any period so applied for not exceeding in all three months from the expiration of the time for payment. (3) If any proceeding is taken in respect of an infringement of the patent committed after a failure to pay any fee within the prescribed time, and before any enlargement thereof, the Court before which the proceeding is taken may, if it thinks fit, refuse to award any damages in respect of such infringement.

15. (1) A patentee may, present a petition to the Government praying that his patent may be extended for a further term; but such petition must be left at the Department of Patents, Designs and Trade Marks at least six months before the time limited for the expiration of the patent and must be accompanied by the prescribed fee and must be advertised by the patentee within the prescribed time and in the prescribed manner. (2) Any person may within such time as may be prescribed and on payment of the prescribed fee give notice to the Registrar of objection to the extension. (3) Where a petition is presented under sub-section (1), the Government may, as it thinks fit, dispose of the petition itself or refer it to the High Court Division for decision.

(5) The Government or the High Court Division to which a petition is referred shall in considering the petition have regard to the nature and merits of the invention in relation to the public, to the profits made on the Patent and to all the circumstances of the case. (6) If it appears to the Government or to the High Court Division when the petition is referred to it that the patent has not been sufficiently remunerative, the Government or the High Court Division as the case may be, may by order extend the term of the patent for a further term not exceeding five or in exceptional cases ten years or may order the grant of a new patent for such term not exceeding ten years as may be specified in the order and subject to any restriction, conditions and provisions which the Government or the High Court Division, as the case may be, may think fit.

¹⁰[15A. (1) Where 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 in his application 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, and, if he does so, a patent (hereinafter referred to as a patent of addition) may be granted for such term as aforesaid. (2) Save as otherwise expressly provided by this Act, a patent of addition shall remain in force as long as the patent for the original invention remains in force, but no longer, and in respect of a patent of addition no fees shall be payable for renewal: Provided that if the patent for the original invention is revoked, then the patent of addition shall, if the authority by which it is revoked 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. (3) 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 and independent patent.]

(4) Where such notice is given the Registrar shall notify the applicant thereof. (5) After the expiration of the prescribed period the Registrar shall hear the case and, subject to an appeal to the Government issue an order either restoring the patent subject to any conditions and restrictions deemed to be advisable or dismissing the application: Provided that in every order under this section restoring a patent such provisions 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 had ceased.

17. (1) An applicant or a patentee may at any time, by request in writing left at the Department of Patents, Designs and Trade Marks and accompanied by the prescribed fee, seek leave to amend his application or specification, including drawings forming part thereof, by way of disclaimer, correction or explanation, stating the nature of, and the reasons for, the proposed amendment. (2) If the application for a patent has not been accepted, the Registrar shall determine whether and subject to what conditions (if any) the amendment shall be allowed. (3) In any other case the request and the nature of the proposed amendment shall be advertised in the prescribed manner, and at any time within three months from its first advertisement any person may give notice at the Department of Patents, Designs and Trade Marks of opposition to the amendment. (4) Where such a notice is given the Registrar shall give notice of the opposition to the person making the request, and shall hear and decide the case. (5) Where no notice of opposition is given, or the person so giving notice of opposition does not appear, the Registrar shall determine whether and subject to what conditions, if any, the amendment ought to be allowed. (6) The decision of the Registrar in either case shall be subject to an appeal to the Government. (7) No amendment shall be allowed that would make the application or specification, as amended, claim an invention substantially larger than, or substantially different from, the invention claimed by the application or specification as it stood before amendment. (8) Leave to amend shall be conclusive as to the right of the party to make the amendment allowed, except in case of fraud; and the amendment shall be advertised in the prescribed manner, and shall in all Courts and for all purposes be deemed to form part of the application or specification. (9) This section shall not apply when and so long as any suit for infringement or proceeding before a Court for the revocation of the patent is pending.

18. In any suit for infringement of a patent or proceeding before a Court for the revocation of a patent the Court may by order allow the patentee to amend his specification by way of disclaimer correction or explanation in such manner, and subject to such terms as to costs, advertisement 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 than, or substantially different from, the invention claimed by the specification as it stood before the amendment, and where an application for such an order is made to the Court notice of the application shall be given to the Registrar, and the Registrar shall have the right to appear and be heard.

19. Where an amendment of a specification by way of disclaimer, correction or explanation has been allowed under this Act, no damages shall be given in any suit 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.

20. (1) There shall be kept at the Department of Patents, Designs and Trade Marks a book called the Register of Patents, wherein shall be entered the names and addresses of grantees of Patents, notifications of assignments and of transmissions of patents, of licenses under patents, and of amendments, extensions, and revocations of patents, and such other matters affecting the validity or proprietorship of patents as may be prescribed. (2) The register of inventions and address book existing at the commencement of this Act shall be incorporated with, and form part of, the register of patents under this Act. (3) The register of patents shall be prima facie evidence of any matters by this Act directed or authorised to be inserted therein. (4) Copies of deeds, licenses and any other documents affecting the proprietorship in any patent or in any license thereunder, must be supplied to the Registrar in the prescribed manner for filing in the Department of Patents, Designs and Trade Marks.

¹¹[21. (1) Subject to the other provisions of this section, a patent shall have to all intents the like effect as against the Government as it has against any person. (2) The officers or authorities administering any department of Government 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 , and after giving notice to the applicant or patentee, make, use or exercise the invention for the service of the Government on such terms as may, either before or after the use thereof, be agreed on, with the approval of the Government between such officers or authorities and the applicant or patentee, or, in default of agreement, as may be settled in the manner hereinafter provided. And the terms of any agreement or license concluded between the applicant or patentee and any person other than such officers or authorities, shall be inoperative so far as concerns the making, use or exercise of the invention for the service of the Government. (3) Where an invention which is the subject of any patent has, before the date of the patent, been duly recorded in a document by, or tried by or on behalf of, the officers or authorities administering any department of Government (such invention not having been communicated directly or indirectly by the applicant or patentee), such officers or authorities, or such of their agents, contractors, or others, as may be authorised in writing by them, may, after giving notice to the applicant or patentee, make, use or exercise the invention so recorded or tried for the service of the Government, free of any royalty or other payment to the applicant or patentee, notwithstanding the existence of the patent. If, in the opinion of such officers or authorities, the disclosure to the applicant or patentee, as the case may be, of the document recording the invention, or the evidence of the trial thereof, if required, would be detrimental to the public interest, it may be made confidentially to counsel on behalf of the applicant or patentee, or to any independent expert mutually agreed upon. (4) In the event of any dispute as to the making, use or exercise of an invention under this section, or the terms therefor, or as to the existence or scope of any record or trial as aforesaid, the matter shall be referred to the High Court Division for decision, who shall have power to refer the whole matter or any question or issue of fact arising thereon to be tried before a special or official referee or an arbitrator upon such terms as it may direct. The Court, referee or arbitrator, as the case may be, may, with the consent of the parties, take into consideration the validity of the patent for the purposes only of the reference and for the determination of the issues between the applicant or patentee and such officers or authorities. The Court, referee, or arbitrator, further, in settling the terms as aforesaid, shall be entitled to take into consideration any benefit or compensation which the applicant or patentee, or any other person interested in the patent, may have received directly or indirectly from the Government or from such officers or authorities in respect of such patent: Provided that, if the inventor or patentee is a Government servant and the subject-matter of the invention is certified by the Government to be connected with work done in the course of such service, any such dispute shall be settled by the Government after hearing the applicant or patentee and any other person having an interest in the invention or patent. (5) The right to use an invention for the services of the Government under the provisions of this section, or any provisions for which this section is substituted, shall include, and shall be deemed always to have included, the power to sell any articles made in pursuance of such right which are no longer required for the services of the Government. (6) Nothing in this section shall affect the right of the Government or of any person deriving title directly or indirectly from the Government to sell or use any articles forfeited under any law for the time being in force relating to customs or excise.

21A. (1) The inventor of any improvement in instruments or munitions of war may (either for or without valuable consideration) assign to the Government all the benefit of the invention and of any patent obtained or to be obtained for the invention; and the Government may be a party to the assignment. (2) The assignment shall effectually vest the benefit of the invention and patent in the Government, and all covenants and agreements therein contained for keeping the invention secret and otherwise shall be valid and effectual (notwithstanding any want of valuable consideration), and may be enforced accordingly by or on behalf of the Government. (3) Where any such assignment has been made, the Government may, at any time before the publication of the specification, certify to the Registrar that, in the interest of the public service, the particulars of the invention and of the manner in which it is to be performed should be kept secret. (4) If the Government so certify, the application and specifications, with the drawings (if any) and any amendment of the specification and any copies of such documents and drawings, shall instead of being left in the ordinary manner at the Department of Patents, Designs and Trade Marks, be delivered to the Registrar in a packet sealed by authority of the Government. (5) The packet shall, until the expiration of the term during which a patent for the invention may be in force, be kept sealed by the Registrar, and shall not be opened save under the authority of an order of the Government. (6) The sealed packet shall be delivered at any time during the continuance of the patent to any person authorised by the Government to receive it, and shall, if returned to the Registrar, be again kept sealed by him. (7) On the expiration of the term of the patent the sealed packet shall be delivered to the Government. (8) Where the Government certifies as aforesaid after an application for a patent has been left at the Department of Patents, Designs and Trade Marks but before the publication of the specification, the application and specifications, with the drawings (if any) shall be forthwith placed in a packet sealed by authority of the Registrar, and the packet shall be subject to the foregoing provisions respecting a packet sealed by authority of the Government. (9) No proceeding by petition or otherwise shall lie for revocation of a patent granted for an invention in relation to which a certificate has been given by the Government as aforesaid. (10) No copy of any specification or other document or drawing, by this section required to be placed in a sealed packet, shall in any manner whatever be published or open to the inspection of the public, but, save as otherwise provided in this section, the provisions of this Act shall apply in respect of any such invention and patent as aforesaid. (11) The Government may at any time waive the benefit of this section with respect to any particular invention, and the specifications, documents and drawings shall be thenceforth kept and dealt with in the ordinary way. (12) The communication of any invention for any improvement in instruments or munitions of war to the Government or to any person or persons authorised by the Government to investigate the same or the merits thereof, shall not, nor shall anything done for the purposes of the investigation, be deemed use or publication of such invention so as to prejudice the grant or validity of any patent for the same.]

22. (1) Any person interested may present a petition to the Government which shall be left at the Department of Patents, Designs and Trade Marks, together with the prescribed fee, alleging that the demand for a patented article in Bangladesh is not being met to an adequate extent and on reasonable terms and praying for the grant of a compulsory license, or, in the alternative, for the revocation of the patent. (2) The Government shall consider the petition, and if the parties do not come to an arrangement between themselves the Government may, as it thinks fit either dispose of the petition itself or refer it to the High Court Division for decision. (3) The provisions of sub-section (4) of section 15, prescribing the procedure to be followed in the case of references to the Court under that section, shall apply in the case of references made to the Court under this section. (4) If the Government is of opinion, or, where a reference has been made under sub-section (2) to the High Court Division, that Court finds that the demand for the patented article in Bangladesh is not being met to an adequate extent and on reasonable terms, the patentee may be ordered to grant licenses on such terms as the Government or the High Court Division, as the case may be, may think just, or, if the Government or the High Court Division is of opinion that the demand will not be adequately met by the grant of licenses, the patent may be revoked by order of the Government or the High Court Division: Provided that an order of revocation shall not be made before the expiration of four years from the date of the patent, or if the patentee gives satisfactory reasons for his default. (5) For the purposes of this section the demand for a patented article shall not be deemed to have been met to an adequate extent and on reasonable terms- (a) if by reason of the default of the patentee to manufacture to an adequate extent and supply on reasonable terms the patented article, or any parts thereof which are necessary for its efficient working, or to carry on the patented process to an adequate extent or to grant licenses on reasonable terms, any existing trade or industry or the establishment of any new trade or industry in Bangladesh is unfairly prejudiced,; or (b) if any trade or industry in Bangladesh is unfairly prejudiced by the conditions attached by the patentee to the purchase, hire or use of the patented article or to the using or working of the patented process.

An order of the High Court Division under section 22 or of the Government under section 22 or section 23, directing the grant of any license shall, without prejudice to any other method of enforcement, operate as if it were embodied in a deed granting a license and executed by the patentee and all other necessary parties.]

23.

(3) No order revoking a patent shall be made under the last sub-section which is at variance with any treaty, convention, arrangement or engagement with any foreign country ¹³[* * *]. (4) The Government may, on the application of the patentee, extend the time limited in any order made under sub-section (2), clause (ii), for such period not exceeding two years as it may specify in a subsequent order, or revoke any order made under sub-section (2), clause (ii), or any subsequent order if sufficient cause is in its opinion shown by the patentee.

24. A patentee may at any time, by giving notice in the prescribed manner to the Registrar, offer to surrender his patent, and the Registrar may, if after giving notice of the offer and hearing all parties who desire to be heard he thinks fit, accept the offer, and thereupon make an order for the revocation of the patent.

25. A patent shall be deemed to be revoked if the Government declares, by notification in the official Gazette the patent or the mode in which it is exercised to be mischievous to the State or generally prejudicial to the public.

30. A patentee shall not be entitled to recover any damages in respect of any infringement of a patent granted after the commencement of this Act from any defendant who proves that at the date of the infringement he was not aware, nor had reasonable means of making himself aware, of the existence of the patent, and the marking of an article with the word “patent,” “patented,” or any word or words expressing or implying that a patent has been obtained for the article, stamped, engraved, impressed on, or otherwise applied to the article, shall not be deemed to constitute notice of the existence of the patent unless the word or words are accompanied by the year and number of the patent: Provided that nothing in this section shall affect any proceedings for an injunction.

¹⁹[38A. A patent shall not be held to be invalid on the ground that the complete specification claims a further or different invention to that contained in the provisional, if the invention therein claimed, so far as it is not contained in the provisional, was novel at the date when the complete specification was put in, and the applicant for the patent was the true and first inventor thereof, or the legal representative or assignee of such inventor.]
