(4) Where a request is made under this section for the correction of any error in a patent or application for a patent or any document filed in pursuance of such an application, and it appears to the Controller that the correction would materially alter the meaning or scope of the document to which the request relates and ought not to be made without notice to persons affected thereby, he shall require notice of the nature of the proposed correction to be advertised in the prescribed manner.

(5) Within the prescribed time after any such advertisement as aforesaid any person interested may give notice to the Controller of opposition to the request, and, where such notice of opposition is given, the Controller shall give notice thereof to the person by whom the request was made, and shall give to him and to the opponent an opportunity to be heard before he decides the case.

79. Evidence how to be given and power of Controller in respect thereof

Subject to any rules made in this behalf, in any proceeding under this Act before the Controller, evidence shall be given by affidavit in the absence of direction by the Controller to the contrary, but in any case in which the Controller thinks it right so to do, he may take oral evidence in lieu of or in addition to, evidence by affidavit, or may allow any party to be cross-examined on the contents of his affidavit.

80. Exercise of discretionary powers by Controller

Without prejudice to any provision contained in this Act requiring the Controller to hear any party to the proceedings thereunder or to give any such party an opportunity to be heard, the Controller shall give to any applicant for a patent, or for amendment of a specification (if within the prescribed time the applicant so requires) an opportunity to be heard before exercising adversely to the applicant any discretion vested in the Controller by or under this Act.

81. Disposal by Controller of applications for extension of time

Where under the provisions of this Act or the rules made thereunder the Controller may extend the time for doing any act, nothing in this Act shall be deemed to require him to give notice to or hear the party interested in opposing the extension, nor shall any appeal lie from any order of the Controller granting such extension.

CHAPTER XVI

WORKING OF PATENTS, COMPULSORY LICENCES,

LICENCES OF RIGHT AND REVOCATION

82. Definition of `patented articles’ and "patentee"

In this Chapter, unless the context otherwise requires, -

1. "patented article" includes any article made by a patented process; and 2. "patentee" includes an exclusive licensee.

83. General principle applicable to working of patented inventions

Without prejudice to the other provisions contained in this Act, in exercising the powers conferred by this Chapter, regard shall be had to the following general considerations, namely -

1. that patents are granted to encourage inventions and to secure that the inventions are worked in India on a commercial scale and to the fullest extent that is reasonably practicable without undue delay; and 2. that they are not granted merely to enable patentees to enjoy a monopoly for the importation of the patented article.

84. Compulsory licences

(1) At any time after the expiration of three years from the date of the sealing of a patent, any person interested may make an application to the Controller alleging that the reasonable requirements of the public with respect to the patented invention have not been satisfied or that the patented invention is not available to the public at a reasonable price and praying for the grant of a compulsory licence to work the patented invention.

(2). 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 that the reasonable requirements of the public with respect to the patented invention are not satisfied or that the patented invention is not available to the public at a reasonable price 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.

(3) Every application under sub-section (1) shall contain a statement setting out the nature of the applicant’s interest together with such particulars as may be prescribed and the facts upon which the application is based.

(4) In considering the application filed under this section the Controller shall take into account the matters set out in section 85.

(5) The Controller, if satisfied that the reasonable requirements of the public with respect to the patented invention have not been satisfied or that the patented invention is not available to the public at a reasonable price, may order the patentee to grant a licence upon such terms as he may deem fit.

(6) Where the Controller directs the patentee to grant a licence he may as incidental thereto exercise the powers set out in section 93.

85. Matter to taken into account in granting compulsory licences

In determining whether or not to make an order in pursuance of an application filed under section 84, the Controller shall take into account, -

(i) 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;

(ii) the ability of the applicant to work the invention to the public advantage;

(iii) the capacity of the applicant to undertake the risk in providing capital and working the invention, if the application were granted,

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

86. Endorsement of patent with the words "Licences of Rights"

(1) At any time after the expiration of three years from the date of the sealing of a patent, the Central Government may make an application to the Controller for an order that the patent may be endorsed with the words "Licences of right" on the ground that the reasonable requirements of the public with respect to the patented invention have not been satisfied or that the patented invention is not available to the public at a reasonable price.

(2) The Controller, if satisfied that the reasonable requirements of the public with respect to the patented invention have not been satisfied or that the patented invention is not available to the public at a reasonable price, may make an order that the patent be endorsed with the words "Licences of right".

(3) Where a patent of addition is in force, any application made under this section for an endorsement either of the original patent or of the patent of addition shall be treated as an application for the endorsement of both patents, and where a patent of addition is granted in respect of a patent which is already endorsed under this section, the patent of addition shall also be so endorsed.

(4) All endorsements of patents made under this section shall be entered in the register and published in the Official Gazette and in such other manner as the Controller thinks desirable for bringing the endorsement to the notice of manufacturers.

87. Certain patents demand to be endorsed with the words "Licences of Rights"

(b) every patent granted after the commencement of this Act in respect of any such invention as is referred to in section 5 shall be deemed to be endorsed with the words "Licences of right" from the date of expiration of three years from the date of sealing of the patent.

(2) In respect of every patent which is deemed to be endorsed with the words "Licences of right" under this section, the provisions of section 88 shall apply.

88. Effect of endorsement of patent with the words is "Licences of Rights".

(1) Where a patent has been endorsed with the words "Licences of right", any person who is interested in working the patented invention in India may require the patentee to grant him a licence for the purpose on such terms as may be mutually agreed upon, notwithstanding that he is already the holder of a licence under the patent.

(2) If the parties are unable to agree on the terms of the licence, either of them may apply in the prescribed manner to the Controller to settle the terms thereof.

(3) The Controller shall, after giving notice to the parties and hearing them and after making such inquiry as he may deem fit, decide the terms on which the licence shall be granted by the patentee.

(4) The Controller may at any time before the terms of the licence are mutually agreed upon or decided by the Controller, on application made to him in this behalf by any person who has made any such requisition as is referred to in sub-section (1), permit him to work the patented invention on such terms as the Controller may, pending agreement between the parties or decision by the Controller, think fit to impose.

(5) In the case of every patent in respect of an invention referred to in sub-clause (i), or sub-clause (ii), of clause (a) of sub-section (1) of section 87 and deemed to be endorsed with the words "Licences of right" under clause (a) or clause (b) of that sub-section, the royalty and other remuneration reserved to the patentee under a licence granted to any person after such commencement shall in no case exceed four per cent of the net ex-factory sale price in bulk of the patented article (exclusive of taxes levied under any law for the time being in force and any commissions payable) determined in such manner as may be prescribed.

(6) Save as otherwise provided in sub-section (5), the provisions of sub-sections (1), (2), (4) and (5) of section 93 (regarding the powers of the Controller) and of sections 94 and 95 shall apply to licences granted under this section as they apply to licences granted under section 84.

89. Revocation of patents by the Controller for non-working.

(1) Where, in respect of a patent, a compulsory licence has been granted or the endorsement "Licences of right" has been made or is deemed to have been made, the Central Government or any person interested may, after the expiration of two years from the date of the order granting the first compulsory licence or, as the case may be, the date of the grant of the first licence under section 88, apply to the Controller for an order revoking the patent on the ground that the reasonable requirements of the public with respect to the patented invention have not been satisfied or that the patented invention is not available to the public at a reasonable price.

(2) Every application under sub-section (1) shall contain such particulars as may be prescribed and the facts upon which the application is based, and, in the case of an application other than by the Central Government, shall also set out the nature of the applicant’s interest.

(4) Every application under sub-section (1) shall ordinarily be decided within one year of its being presented to the Controller.

90. When reasonable requirements of the public deemed not satisfied

For the purposes of sections 84, 86 and 89, the reasonable requirements of the public shall be deemed not to have been satisfied -

1. if, by reason of the default of the patentee to manufacture in India to an adequate extent and supply on reasonable terms the patented article or a part of the patented article which is necessary for its efficient working or if, by reason of the refusal of the patentee to grant a licence or licences on reasonable terms, -

(i) an existing trade or industry or the development thereof or the establishment of any new trade or industry in India or the trade or industry of any person or classes of persons trading or manufacturing in India is prejudiced; or

(ii) the demand for the patented article is not being met to an adequate extent or on reasonable terms from manufacture in India; or

(iii) a market for the export of the patented article manufactured in India is not being supplied or developed; or

(iv) the establishment or development of commercial activities in India is prejudiced; or  2. if, by reason of conditions imposed by the patentee (whether before or after the commencement of this Act) 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 any trade or industry in India, is prejudiced; or   3. if the patented invention is not being worked in India on a commercial scale to an adequate extent or is not being so worked to the fullest extent that is reasonably practicable; or   4. if the demand for the patented article in India is being met to a substantial extent by importation from abroad by -

(i) the patentee or persons claiming under him; or

(ii) persons directly or indirectly purchasing from him; or

(iii) other persons against whom the patentee is not taking or has not taken proceedings for infringement; or

(e) if the working of the patented invention in India on a commercial scale is being prevented or hindered by the importation from abroad of the patented article by the patentee or the other persons referred to in the preceding clause.

91. Power of Controller to adjourn applications for compulsory licenses, etc., in certain cases

(1) Where an application under section 84, section 86 or section 89, as the case may be, is made on the ground mentioned in clause (c) of section 90 and the Controller is satisfied that the time which has elapsed since the sealing of the patent has for any reason been insufficient to enable the invention to be worked on a commercial scale to an adequate extent or to enable the invention to be so worked to the fullest extent that is reasonably practicable, he may, by order adjourn the further hearing of the application for such period not exceeding twelve months in the aggregate as appears to him to be sufficient for the invention to be so worked:

Provided that the in any case where the patentee establishes that the reason why a patented invention could not be worked as aforesaid before the date of the application was due to any State or Central Act or any rule or regulation made thereunder or any order of the Government imposed otherwise than by way of a condition for the working of the invention in India or for the disposal of the patented articles or of the articles made by the process or by the use of the patented plant, machinery, or apparatus, then, the period of adjournment ordered under this sub-section shall be reckoned from the date on which the period during which the working of the invention was prevented by such Act, rule or regulation or order of Government as computed from the date of the application, expires.

(2) No adjournment under sub-section (1) shall be ordered unless the Controller is satisfied that the patentee has taken with promptitude adequate or reasonable steps to start the working of the invention in India on a commercial scale and to an adequate extent.

92. Procedure for dealing with applications under sections 84, 86 and 89

(1) Where the Controller is satisfied, upon consideration of an application under section 84, section 86 or section 89, 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 person appearing from the register to be interested in the patent in respect of which the application is made, and shall advertise the application in the Official Gazette.

(2) 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 Controller may on application (made either before or after the expiration of the prescribed time) allow, give to the Controller notice of opposition.

(3) Any such notice of opposition shall contain a statement setting out the grounds on which the application is opposed.

(4) Where any such notice of opposition is duly given, the Controller shall notify the applicant, and shall give to the applicant and the opponent an opportunity to be heard before deciding the case.

93. Powers of Controller in granting compulsory licences

(1) Where the Controller is satisfied on application made under section 84 that the manufacture, use or sale of materials not protected by the patent is 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 section 84 is made by a person being the holder of a licence under the patent, the Controller 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 made under section 84, the Controller orders the grant of a licence, he may, for reasons to be recorded in writing, direct that the licence shall operate -

1. 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; 2. to revoke all existing licences in respect of the invention.

(4) Where two or more patents are held by the same patentee and an applicant for a compulsory licence establishes that the reasonable requirements of the public have not been satisfied with respect to some only of the said patents, then, if the Controller is satisfied that the applicant cannot efficiently or satisfactorily work the licence granted to him under those patents without infringing the other patents held by the patentee, he may, by order, direct the grant of a licence in respect of the other patents also to enable the licensee to work the patent or patents in regard to which a licence is granted under section 84.

(5) Where the terms and conditions of a licence have been settled by the Controller, the licensee may, at any time after he has worked the invention on a commercial scale for a period of not less than twelve months, make an application to the Controller for the revision of the terms and conditions on the ground that the terms and conditions settled have proved to be more onerous than originally expected and that in consequence thereof the licensee is unable to work the invention except at a loss:

Provided that no such application shall be entertained a second time.

94. General purposes for granting compulsory licences

The powers of the Controller upon an application made under section 84 shall be exercised with a view to securing the following general purposes, that is to say, -

1. that patented inventions are worked on a commercial scale in India without undue delay and to the fullest extent that is reasonably practicable; 2. that the interests of any person for the time being working or developing an invention in India under the protection of a patent are not unfairly prejudiced.

95. Terms and conditions of compulsory licences

(1) In settling the terms and conditions of a licence under section 84, the Controller shall endeavour to secure -

(i) that the royalty and other remuneration, if any, reserved to the patentee or other person beneficially entitled to the patent, is reasonable, having regard to the nature of the invention, the expenditure incurred by the patentee in making the invention or in developing it and obtaining a patent and keeping it in force and other relevant factors;

(ii) that the patented invention is worked to the fullest extent by the person to whom the licence is granted and with reasonable profit to him;

(iii) that the patented articles are made available to the public at reasonable prices.

(2) No licence granted by the Controller shall authorise the licensee to import the patented article or an article or substance made by a patented process from abroad where such importation would, but for such authorisation, constitute an infringement of the rights of the patentee.

(3) Notwithstanding anything contained in sub-section (2), the Central Government may, if in its opinion it is necessary so to do in the public interest, direct the Controller at any time to authorise any licensee in respect of a patent to import the patented article or an article or substance made by a patented process from abroad (subject to such conditions as it considers necessary to impose relating among other matters to the royalty and other remuneration, if any, payable to the patentee, the quantum of import, the sale price of the imported article and the period of importation), and thereupon the Controller shall give effect to the directions.

96. Licensing of related patents

(1) Notwithstanding anything contained in the other provisions of this Chapter, at any time after the sealing of a patent, any person who has the right to work any other patented invention either as patentee or as licensee thereof, exclusive or otherwise, may apply to the Controller for the grant of a licence of the first mentioned patent on the ground that he is prevented or hindered without such licence from working the other invention efficiently or to the best advantage possible.

(2) No order under sub-section (1) shall be made unless the Controller is satisfied -

(i) that the applicant is able and willing to grant, or procure the grant to the patentee and his licensees if they so desire, of a licence in respect of the other invention on reasonable terms; and

(ii) that the other invention has made a substantial contribution to the establishment or development of commercial or industrial activities in India.

(3) When the Controller is satisfied that the conditions mentioned in sub-section (1) have been established by the applicant, he may make an order on such terms as he thinks fit granting a licence under the first mentioned patent and a similar order under the other patent if so requested by the proprietor of the first mentioned patent or his licensee.

(4) The provisions of sections 92 and 110 shall apply to licences granted under this section as they apply to licences granted under section 84.

97. Special provisions for compulsory licences on notifications by Central Government

(1) If the Central Government is satisfied in respect of any patent or class of patents in force that is necessary or expedient in the public interest that compulsory licences should be granted at any time after the sealing thereof to work the invention or inventions, it may make a declaration to that effect in the Official Gazette, and thereupon the following provisions shall have effect, that is to say -

(i) the Controller shall on application made at any time after the notification by any person interested grant to the applicant a licence under the patent on such terms as he thinks fit;

(ii) in settling the terms of a licence granted under this section, the Controller shall endeavour to secure that the articles manufactured under the patent shall be available to the public at the lowest prices consistent with the patentees deriving a reasonable advantage from their patent rights.

(2) The provisions of sections 92, 93, 94 and 95 shall apply in relation to the grant of licences under this section as they apply in relation to the grant of licences under section 84.

98. Order for licence to operate as a deed between parties concerned

Any order for the grant of a licence under this Chapter shall operate as if it were a deed granting a licence executed by the patentee and all other necessary parties embodying the terms and conditions, if any, settled by the Controller.

shall also be deemed, for the purposes of this Chapter, to be use of such invention for the purposes of Government.

(3) Nothing contained in this Chapter shall apply in respect of any such importation making or using of any machine, apparatus or other article or of any such using of any process or of any such importation, using or distribution of any medicine or drug, as may be made by virtue of one or more of the conditions specified in section 47.

100. Power of Central Government to use inventions for purposes of Government

(1) Notwithstanding anything contained in this Act, at any time after an application for a patent has been filed at the patent office or a patent has been granted, the Central Government and any person authorised in writing by it, may use the invention for the purposes of Government in accordance with the provisions of this Chapter.

(2) Where an invention has, before the priority date of the relevant claim of the complete specification, been duly recorded in a document, or tested or tried, by or on behalf of the Government or a Government undertaking, otherwise than in consequence of the communication of the invention directly or indirectly by the patentee or by a person from whom he derives title, any use of the invention by the Central Government or any person authorised in writing by it for the purposes of Government may be made free of any royalty or other remuneration to the patentee.

(3) If and so far as the invention has not been so recorded or tried or tested as aforesaid, any use of the invention made by the Central Government or any person authorised by it under sub-section (1), at any time after the acceptance of the complete specification in respect of the patent or in consequence of any such communication as aforesaid, shall be made upon terms as may be agreed upon either before or after the use, between the Central Government or any person authorised under sub-section (1) and the patentee, or, as may in default of agreement be determined by the High Court on a reference under section 103:

Provided that in the case of any such use of any patent in respect of any medicine or drug or article of food the royalty and other remuneration shall in no case exceed four per cent of the net ex-factory sale price in bulk of the patented article (exclusive of taxes levied under any law for the time being in force and any commissions payable) determined in such manner as may be prescribed.

(4) The authorisation by the Central Government in respect of an invention may be given under this section, either before or after the patent is granted and either before or after the acts in respect of which such authorisation is given or done, and may be given to any person, whether or not he is authorised directly or indirectly by the applicant or the patentee to make, use, exercise or vend the invention or import the machine, apparatus or other article or medicine or drug covered by such patent.

(5) Where an invention has been used by or with the authority of the Central Government for the purposes of Government under this section, then, unless it appears to the Government that it would be contrary to the public interest so to do, the Government shall notify the patentee as soon as practicable of the fact and furnish him with such information as to the extent of the use of the invention as he may, from time to time, reasonably require; and where the invention has been used for the purposes of a Government undertaking, the Central Government may call for such information as may be necessary for this purpose from such undertaking.

(6) The right to make, use, exercise and vend an invention for the purposes of Government under sub-section (1) shall include the right to sell the goods which have been made in exercise of that right, and a purchaser of goods so sold, and a person claiming through him, shall have the power to deal with the goods as if the Central Government or the person authorised under sub-section (1) were the patentee of the invention.

(7) Where in respect of a patent which has been the subject matter of an authorisation under this section, there is an exclusive licensee as is referred to in sub-section (3) of section 101, or where such patent has been assigned to the patentee in consideration of royalties or other benefits determined by reference to the use of the invention (including payments by way of minimum royalty), the notice directed to be given under sub-section (5) shall also be given to such exclusive licensee or assignor, as the case may be, and the reference to the patentee in sub-section (3) shall be deemed to include a reference to such assignor or exclusive licensee.

101. Rights of third parties in respect of use of invention for purposes of Government

(1) In relation to any use of a patented invention, or an invention in respect of which an application for a patent is pending, made for the purposes of Government -

1. by the Central Government or any person authorised by the Central Government under section 100; or  2. by the patentee or applicant for the patent to the order made by the Central Government,

the provisions of any licence, assignment or agreement granted or made, whether before or after the commencement of this Act, between the patentee or applicant for the patent (or any person who derives title from him or from whom he derives title) and any person other than the Central Government shall be of no effect so far as those provisions -

(i) restrict or regulate the use for the purposes of Government of the invention, or of any model, document or information relating thereto, or

(ii) provide for the making of payments in respect of any use of the invention or of the model, document or information relating thereto for the purposes of Government (including payments by way of minimum royalty),

and the reproduction or publication of any model or document in connection with the said use for the purposes of Government shall not be deemed to be an infringement of any copyright subsisting in the model or document.

(2) Where the patent, or the right to apply for or obtain the patent, has been assigned to the patentee in consideration of royalties or other benefits determined by reference to the use of the invention (including payments by way of minimum royalty), then, in relation to any use of the invention made for the purposes of Government by the patentee to the order of the Central Government, sub-section (3) of section 100 shall have effect as if that use were made by virtue of an authority given under that section; and any use of the invention for the purposes of Government by virtue of sub-section (3) of that section shall have effect as if the reference to the patentee included a reference to the assignor of the patent, and any sum payable by virtue of that sub-section shall be divided between the patentee and the assignor in such proportion as may be agreed upon between them or as may in default of agreement be determined by the High Court on a reference under section 103.

(3) Where by virtue of sub-section (3) of section 100, payments are required to be made by the Central Government or persons authorised under sub-section (1) of that section in respect of the use of an invention for the purposes of Government and where in respect of such patent there is an exclusive licensee authorised under his licence to use the invention for the purposes of Government, such sum shall be shared by the patentee and such licensee in such proportions, if any, as may be agreed upon between them or as may in default of agreement be determined by the High Court on a reference under section 103 to be just, having regard to any expenditure incurred by the licensee -

1. in developing the said invention; or  2. in making payments to the patentees other than royalties or other benefits determined by reference to the use of the invention including payments by way of minimum royalty in consideration of the licence.

102. Acquisition of inventions and patents by the Central Government

(1) The Central Government may, if satisfied that it is necessary that an invention which is the subject of an application for a patent or a patent should be acquired from the applicant or the patentee for a public purpose, publish a notification to that effect in the Official Gazette, and thereupon the invention or patent and all rights in respect of the invention or patent shall, by force of this section, stand transferred to and be vested in the Central Government.

(2) Notice of the acquisition shall be given to the applicant, and, where a patent has been granted, to the patentee and other persons, if any, appearing in the register as having an interest in the patent.

(3) The Central Government shall pay to the applicant, or, as the case may be, the patentee and other persons appearing on the register as having an interest in the patent such compensation as may be agreed upon between the Central Government and the applicant, or the patentee and other persons; or, as may, in default of agreement, be determined by the High Court on a reference under section 103 to be just having regard to the expenditure incurred in connection with the invention and, in the case of a patent, the term thereof, the period during which and the manner in which it has already been worked (including the profits made during such period by the patentee or by his licensee whether exclusive or otherwise) and other relevant factors.

103. Reference to High Court of disputes as use for purposes of Government

(1) Any dispute as to the exercise by the Central Government or a person authorised by it of the powers conferred by section 100, or as to terms for the use of an invention for the purposes of Government thereunder or as to the right of any person to receive any part of a payment made in pursuance of sub-section (3) of that section or as to the amount of compensation payable for the acquisition of an invention or a patent under section 102, may be referred to the High Court by either party to the dispute in such manner as may be prescribed by the rules of the High Court.

(2) In any proceedings under this section to which the Central Government is a party, the Central Government may, -

1. if the patentee is a party to the proceedings, petition by way of counter-claim for revocation of the patent on any ground upon which a patent may be revoked under section 64; and 2. whether a patentee is or is not a party to the proceedings, put in issue the validity of the patent without petitioning for its revocation.

(3) If in such proceedings as aforesaid any question arises whether an invention has been recorded, tested or tried as is mentioned in section 100, and the disclosure of any document regarding the invention, or of any evidence of the test or trial thereof, would, in the opinion of the Central Government, be prejudicial to the public interest, the disclosure may be made confidentially to the advocate of the other party or to an independent expert mutually agreed upon.

CHAPTER XVIII

SUITS CONCERNING INFRINGEMENT OF PATENTS

104. Jurisdiction

No suit for a declaration under section 105 or for any relief under section 106 or for infringement of a patent shall be instituted in any court inferior to a district court having jurisdiction to try to suit:

Provided that where a counter-claim for revocation of the patent is made by the defendant, the suit, along with the counter-claim, shall be transferred to the High Court for decision.

105. Power of Court to make declaration as to non-infringement

(1) Notwithstanding anything contained in section 34 of the Specific Relief Act, 1963, any person may institute a suit for a declaration that the use by him of any process, or the making, use or sale of any article by him does not, or would not, constitute an infringement of a claim of a patent against the patentee or the holder of an exclusive licence under the patent, notwithstanding that no assertion to the contrary has been made by the patentee or the licensee, if it is shown -

1. that the plaintiff has applied in writing to the patentee or exclusive licensee for a written acknowledgement to the effect of the declaration claimed and has furnished him with full particulars in writing of the process or article in question; and 2. that the patentee or licensee has refused or neglected to give such an acknowledgement.

(2) The costs of all parties in a suit for a declaration brought by virtue of this section shall, unless for special reasons the court thinks fit to order otherwise, be paid by the plaintiff.

(3) The validity of a claim of the specification of a patent shall not be called in question in a suit for a declaration brought by virtue of this section, and accordingly the making or refusal of such a declaration in the case of a patent shall not be deemed to imply that the patent is valid or invalid.

(4) A suit for a declaration may be brought by virtue of this section at any time after the date of advertisement of acceptance of the complete specification of a patent, and references in this section to the patentee shall be construed accordingly.

106. Power of Court to grant relief in cases of groundless threat of infringement proceedings

(1) Where any person (whether entitled to or interested in a patent or an application for a patent or not) threatens any other person by circulars or advertisements or by communications, oral or in writing addressed to that or any other person, with proceedings for infringement of a patent, any person aggrieved thereby may bring a suit against him praying for the following reliefs, that is to say -

1. a declaration to the effect that the threats are unjustifiable; 2. an injunction against the continuance of the threats; and 3. such damages, if any, as he has sustained thereby.

(2) Unless in such suit the defendant proves that the acts in respect of which the proceedings were threatened constitute or, if done, would constitute, an infringement of a patent or of rights arising from the publication of a complete specification in respect of a claim of the specification not shown by the plaintiff to be invalid, the court may grant to the plaintiff all or any of the reliefs prayed for.

Explanation – A mere notification of the [existence] of a patent does not constitute a threat of proceeding within the meaning of this section.

107. Defences etc., in suits for infringement

(1) In any suit for infringement of a patent, every ground on which it may be revoked under section 64 shall be available as a ground for defence.

(2) In any suit for infringement of a patent by the making, using or importation of any machine, apparatus or other article or by the using of any process or by the importation, use or distribution of any medicine or drug, it shall be a ground for defence that such making, using importation or distribution is in accordance with any or more of the conditions specified in section 47.

108. Reliefs in suits for infringement

The reliefs which a court may grant in any suit for infringement include an injunction (subject to such terms, if any, as the court thinks fit) and, at the option of the plaintiff, either damages or an account of profits.

109. Rights of exclusive licencee to take proceedings against infringement

(1) The holder of an exclusive licence shall have the like right as the patentee to institute a suit in respect of any infringement of the patent committed after the date of the licence, and in awarding damages or an account of profits or granting any other relief in any such suit the court shall take into consideration any loss suffered or likely to be suffered by the exclusive licensee as such or, as the case may be, the profits carried by means of the infringement so far as it constitutes an infringement of the rights of the exclusive licensee as such.

(2) In any suit for infringement of a patent by the holder of an exclusive licence under sub-section (1), the patentee shall, unless he has joined as a plaintiff in the suit, be added as a defendant, but a patentee so added as defendant shall not be liable for any costs unless he enters an appearance and takes part in the proceedings.

110. Right of licencee under section 84 to take proceedings against infringement

Any person to whom a licence has been granted under section 84 shall be entitled to call upon the patentee 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 though he were the patentee, making the patentee a defendant; but a patentee so added as defendant shall not be liable for any costs unless he enters an appearance and takes part in the proceedings.

111. Restoration on power of Courts to grant damages or account of profits for infringement

(1) In a suit for infringement of a patent, damages or an account of profits shall not be granted against the defendant who proves that at the date of the infringement he was not aware and had no reasonable grounds for believing that the patent existed.

Explanation – A person shall not be deemed to have been aware or to have had reasonable grounds for believing that a patent exists by reason only of the application to an article of the word "patent", "patented" or any word or words expressing or implying that a patent has been obtained for the article, unless the number of the patent accompanies the word or words in question.

(2) In any suit for infringement of a patent the court may, if it thinks fit, refuse to grant any damages or an account of profits in respect of any infringement committed after a failure to pay any renewal fee within the prescribed period and before any extension of that period.

(3) Where an amendment of a specification by way of disclaimer, correction or explanation has been allowed under this Act after the publication of the specification, no damages or account of profits shall be granted in any proceeding in respect of the use of the invention before the date of the decision allowing the amendment, unless the court is satisfied that the specification as originally published was framed in good faith and with reasonable skill and knowledge.

(4) Nothing in this section shall affect the power of the court to grant an injunction in any suit for infringement of a patent.

112. Restriction of power of Court to grant injunction in certain cases

If in proceedings for the infringement of a patent endorsed or deemed to be endorsed with the words "Licences of right" (otherwise than by the importation of the patented article from other countries) the infringing defendant is ready and willing to take a licence upon terms to be settled by the Controller as provided in section 88, no injunction shall be granted against him, and the amount if any recoverable against him by way of damages shall not exceed double the amount which would have been recoverable against him as licensee if such a licence had been granted before the earliest infringement.

113. Certificate of validity of specification and costs of subsequent suits for infringement thereof

(1) If in any proceedings before a High Court for the revocation of a patent under section 64 the validity of any claim of a specification is contested and that claim is found by the Court to be valid, the Court may certify that the validity of that claim was contested in those proceedings and was upheld.

(2) Where any such certificate has been granted, then, if in any subsequent suit before a court for infringement of that claim of the patent or in any subsequent proceeding for revocation of the patent in so far as it relates to that claim, the patentee or other person relying on the validity of the claim obtains a final order or judgement in his favour, he shall be entitled to an order for the payment of his full costs, charges and expenses of and incidental to any such suit or proceeding properly incurred so far as they concern the claim in respect of which the certificate was granted, unless the court trying the suit or proceeding otherwise directs:

Provided that the costs as specified in this sub-section shall not be ordered when the party disputing the validity of the claim satisfies the court that he was not aware of the grant of the certificate when he raised the dispute and withdrew forthwith such defence when he became aware of such a certificate.

(3) Nothing contained in this section shall be construed as authorising courts hearing appeals from decrees or orders in suits for infringement or petitions for revocation to pass orders for costs on the scale referred to therein.

114. Relief for infringement of partially valid specification

(1) If in proceedings for infringement of a patent it is found that any claim of the specification, being a claim in respect of which infringement is alleged, is valid, but that any other claim is invalid, the court may grant relief in respect of any valid claim which is infringed:

Provided that the court shall not grant relief except by way of injunction save in the circumstances mentioned in sub-section (2).

(2) Where the plaintiff proves that the invalid claim was framed in good faith and with reasonable skill and knowledge, the court shall grant relief in respect of any valid claim which is infringed subject to the discretion of the court as to costs and as to the date from which damages or an account of profits should be reckoned, and in exercising such discretion the court may take into consideration the conduct of the parties in inserting such invalid claims in the specification or permitting them to remain there.

115. Scientific advisers

(1) In any suit for infringement or in any proceeding before a court under this Act, the court may at any time, and whether or not an application has been made by any party for that purpose, appoint an independent scientific adviser to assist the court or to inquire and report upon any such question of fact or of opinion (not involving a question of interpretation of law) as it may formulate for the purpose.

(2) The remuneration of the scientific adviser shall be fixed by the court and shall include the costs of making a report and a proper daily fee and any day on which the scientific adviser may be required to attend before the court, and such remuneration shall be defrayed out of moneys provided by Parliament by law for the purpose.
