Power of Controller to make orders respecting division of application.—(1) A person who has made an application for a patent under this Act may, at any time 1[before the grant of the patent], if he so desires, or with a view to remedy the objection raised by the Controller on the ground that the claims of the complete specification relate to more than one invention, file a further application in respect of an invention disclosed in the provisional or complete specification already filed in respect of the first mentioned application.

(2) The further application under sub-section (1) shall be accompanied by a complete specification, but such complete specification shall not include any matter not in substance disclosed in the complete specification filed in pursuance of the first mentioned application.

(3) The Controller may require such amendment of the complete specification filed in pursuance of either the original or the further application as may be necessary to ensure that neither of the said complete specifications includes a claim for any matter claimed in the other.

2[Explanation.— For the purposes of this Act, the further application and the complete specification accompanying it shall be deemed to have been filed on the date on which the first mentioned application had been filed, and the further application shall be proceeded with as a substantive application and be examined when the request for examination is filed within the prescribed period.]

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 Controller.

(3) If it appears to the Controller, as a result of an investigation under section 13 or otherwise,—

(a) that the invention so far as claimed in any claim of the applicant’s complete specification

has been claimed in any other complete specification referred to in clause (a) of sub-section (1) of section 13; and

(b) that such other complete specification was published on or after the priority date of the

applicant’s claim,

then, unless it is shown to the satisfaction of the Controller that the priority date of the applicant’s claim is not later than the priority date of the claim of that specification, the provisions of sub-section (2) shall apply thereto in the same manner as they apply to a specification published on or after the date of filing of the applicant’s complete specification.

Powers of Controller in case of potential infringement.—(1) If, in consequence of the investigations required 2[under this Act], it appears to the Controller that an invention in respect of which an 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—

(a) the applicant shows to the satisfaction of the Controller that there are reasonable grounds for

contesting the validity of the said claim of the other patent; or

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

(c) it is found, in proceedings before the court or the Controller, that the relevant claim of that other patent is invalid or is not infringed by any working of the applicant’s invention, the Controller may, on the application of the applicant, delete the reference to that other patent.

Powers of Controller to make orders regarding substitution of applicants, etc.—(1) If the Controller 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 in writing 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 Controller 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 claimants and the applicant or the other joint applicant or applicants, accordingly 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.

(5) If any dispute arises between joint applicants for a patent whether or in what manner the application should be proceeded with, the Controller may, upon application made to him in the prescribed manner by any of the parties, and after giving to all parties concerned an opportunity to be heard, give such directions as he thinks fit for enabling the application to proceed in the name of one or more of the parties alone or for regulating the manner in which it should be proceeded with, or for both those purposes, as the case may require.

1[21. Time for putting application in order for grant.—(1) An application for a patent shall be deemed to have been abandoned unless, within such period as may be prescribed, the applicant has complied with all the requirements imposed on him by or under this Act, whether in connection with the complete specification or otherwise in relation to the application from the date on which the first statement of objections to the application or complete specification or other documents related thereto is forwarded to the applicant by the Controller.

Explanation.—Where the application for a patent or any specification or, in the case of a convention application or an application filed under the Patent Cooperation Treaty designating India any document filed as part of the application has been returned to the applicant by the Controller in the course of the proceedings, the applicant shall not be deemed to have complied with such requirements unless and until he has refiled it or the applicant proves to the satisfaction of the Controller that for the reasons beyond his control such document could not be refiled.

(6) In case the Controller issues an order under sub-section (4) that the patent shall be maintained subject to amendment of the specification or any other document, the patent shall stand amended accordingly.

In cases of “obtaining” Controller may

treat

the patent as

the patent of

(2) Where the Controller gives any such directions as are referred to in sub-section (1), he shall give notice of the application and of the directions to the Central Government, and the Central Government shall, upon receipt of such notice, consider whether the publication of the invention would be prejudicial to the defence of India, and if upon such consideration, it appears to it that the publication of the invention would not so prejudice, give notice to the Controller to that effect, who shall thereupon revoke the directions and notify the applicant accordingly.

(3) Without prejudice to the provisions contained in sub-section (1), where the Central Government
is of opinion that an invention in respect of which the Controller has not given any directions under
sub-section (1), is relevant for defence purposes, it may at any time before 3[grant of patent] notify the Controller to that effect, and thereupon the provisions of that sub-section shall apply as if the invention were one of the class notified by the Central Government, and accordingly the Controller shall give notice to the Central Government of the directions issued by him.

83. General principles 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:—

(a) 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;

(b) that they are not granted merely to enable patentees to enjoy a monopoly for the importation

of the patented article;

(c) that the protection and enforcement of patent rights contribute to the promotion of technological innovation and to the transfer and dissemination of technology, to the mutual advantage of producers and users of technological knowledge and in a manner conducive to social and economic welfare, and to a balance of rights and obligations;

(d) that patents granted do not impede protection of public health and nutrition and should act as instrument to promote public interest specially in sectors of vital importance for socio-economic and technological development of India;

(e) that patents granted do not in any way prohibit Central Government in taking measures to

protect public health;

(f) that the patent right is not abused by the patentee or person deriving title or interest on patent from the patentee, and the patentee or a person deriving title or interest on patent from the patentee does not resort to practices which unreasonably restrain trade or adversely affect the international transfer of technology; and

(g) that patents are granted to make the benefit of the patented invention available at reasonably

affordable prices to the public.

Compulsory licences.—(1) At any time after the expiration of three years from the date of the 1[grant] of patent, any person interested may make an application to the Controller for grant of compulsory licence on patent on any of the following grounds, namely:—

(a) that the reasonable requirements of the public with respect to the patented invention have not

been satisfied, or

(b) that the patented invention is not available to the public at a reasonably affordable price, or

(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 worked in the territory of India or that the patented invention is not available to the public at a reasonably affordable 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) 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 worked in the territory of India or that the patented invention is not available to the public at a reasonably affordable price, may grant a licence upon such terms as he may deem fit.

(5) Where the Controller directs the patentee to grant a licence he may, as incidental thereto, exercise

the powers set out in section 88.

Subs. by Act 15 of 2005, s. 52, for “sealing” (w.e.f. 1-1-2005).

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;

(iv) as to whether the applicant has made efforts to obtain a licence from the patentee on reasonable terms and conditions and such efforts have not been successful within a reasonable period as the Controller may deem fit:

Provided that this clause shall not be applicable in case of national emergency or other circumstances of extreme urgency or in case of public non-commercial use or on establishment of a ground of anti-competitive practices adopted by the patentee,

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

1[Explanation.—For the purposes of clause (iv), “reasonable period” shall be construed as a period

not ordinarily exceeding a period of six months.]

(7) For the purposes of this Chapter, the reasonable requirements of the public shall be deemed not to

have been satisfied—

(a) 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 class of persons trading or manufacturing in India is prejudiced; or

(ii) the demand for the patented article has not been met to an adequate extent or on

reasonable terms; or

(iii) a market for 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

(b) if, 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 any trade or industry in India, is prejudiced; or

(c) if the patentee imposes a condition upon the grant of licences under the patent to provide exclusive grant back, prevention to challenges to the validity of patent or coercive package licensing, or

(d) if the patented invention is not being worked in the territory of India on a commercial scale to

(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.

The Explanation ins. by Act 15 of 2005, s. 52 (w.e.f. 1-1-2005).

85. Revocation of patents by the Controller for non-working.—(1) Where, in respect of a patent, a compulsory licence has been granted, 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, apply to the Controller for an order revoking the patent on the ground that the patented invention has not been worked in the territory of India or that reasonable requirements of the public with respect to the patented invention has not been satisfied or that the patented invention is not available to the public at a reasonably affordable price.

(2) Every application under sub-section (1) shall contain such particulars as may be prescribed, 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.

(3) The Controller, if satisfied that the reasonable requirements of the public with respect to the patented invention have not been satisfied or that patented invention have not been worked in the territory of India or that the patented invention is not available to the public at a reasonably affordable price, may make an order revoking the patent.

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

presented to the Controller.

Power of Controller to adjourn applications for compulsory licences, etc., in certain
cases.—(1) Where an application under section 84 or section 85, as the case may be, is made on the grounds that the patented invention has not been worked in the territory of India or on the ground mentioned in clause (d) of sub-section (7) of section 84 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 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 the territory of 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 the territory of India on a commercial scale and to an adequate extent.

Procedure for dealing with applications under sections 84 and 85.—(1) Where the Controller is satisfied, upon consideration of an application under section 84, or section 85, 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 1[shall publish the application in the official journal].

(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.

Subs. by Act 15 of 2005, s. 53, for “shall advertise the application in the Official Gazette” (w.e.f. 1-1-2005).

(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.

Powers of Controller in granting compulsory licences.—(1) Where the Controller is satisfied on an 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 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 and if those patents involve important technical advancement or considerable economic significance in relation to the other patents, 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.

(4) 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.

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,—

(a) that patented inventions are worked on a commercial scale in the territory of India without

undue delay and to the fullest extent that is reasonably practicable;

(b) that the interests of any person for the time being working or developing an invention in the

territory of India under the protection of a patent are not unfairly prejudiced.

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 reasonably affordable prices;

(iv) that the licence granted is a non-exclusive licence;

(v) that the right of the licensee is non-assignable;

(vi) that the licence is for the balance term of the patent unless a shorter term is consistent with

public interest;

1[(vii) that the licence is granted with a predominant purpose of supply in the Indian market and that the licensee may also export the patented product, if need be in accordance with the provisions of sub-clause (iii) of clause (a) of sub-section (7) of section 84;

(viii) that in the case of semi-conductor technology, the licence granted is to work the invention

for public non-commercial use;

(ix) that in case the licence is granted to remedy a practice determined after judicial or administrative process to be anti-competitive, the licensee shall be permitted to export the patented product, if need be.]

(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.

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 the territory of 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:

Provided that the licence granted by the Controller shall be non-assignable except with the

assignment of the respective patents.

(4) The provisions of sections 87, 88, 89 and 90 shall apply to licences granted under this section as

they apply to licences granted under section 84.

Special provision for compulsory licences on notifications by Central Government.—(1) If the Central Government is satisfied, in respect of any patent in force in circumstances of national emergency or in circumstances of extreme urgency or in case of public non-commercial use, that it is necessary that compulsory licences should be granted at any time after the sealing thereof to work the invention, it may make a declaration to that effect, by notification 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 and conditions as he thinks fit;

Subs. by Act 15 of 2005, s. 54, for clause (vii) (w.e.f. 1-1-2005).

(ii) in settling the terms and conditions 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 83, 87, 88, 89 and 90 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.

(i) a circumstance of national emergency; or

(ii) a circumstance of extreme urgency; or

(iii) a case of public non-commercial use,

which may arise or is required, as the case may be, including public health crises, relating to Acquired Immuno Deficiency Syndrome, human immunodeficiency virus, tuberculosis, malaria or other epidemics, he shall not apply any procedure specified in section 87 in relation to that application for grant of licence under this section:

Provided that the Controller shall, as soon as may be practicable, inform the patentee of the patent

relating to the application for such non-application of section 87.

1[92A. Compulsory licence for export of patented pharmaceutical products in certain exceptional circumstances.—(1) Compulsory licence shall be available for manufacture and export of patented pharmaceutical products to any country having insufficient or no manufacturing capacity in the pharmaceutical sector for the concerned product to address public health problems, provided compulsory licence has been granted by such country or such country has, by notification or otherwise, allowed importation of the patented pharmaceutical products from India.

(2) The Controller shall, on receipt of an application in the prescribed manner, grant a compulsory licence solely for manufacture and export of the concerned pharmaceutical product to such country under such terms and conditions as may be specified and published by him.

(3) The provisions of sub-sections (1) and (2) shall be without prejudice to the extent to which pharmaceutical products produced under a compulsory licence can be exported under any other provision of this Act.

Termination of compulsory licence.—(1) On an application made by the patentee or any other person deriving title or interest in the patent, a compulsory licence granted under section 84 may be terminated by the Controller, if and when the circumstances that gave rise to the grant thereof no longer exist and such circumstances are unlikely to recur:

Provided that the holder of the compulsory licence shall have the right to object to such termination.

(2) While considering an application under sub-section (1), the Controller shall take into account that

the interest of the person who had previously been granted the licence is not unduly prejudiced.].

undertaking and the subject-matter of the invention is certified by the relevant Government or the principal officer of the Government undertaking to be connected with the work done in the course of the normal duties of the Government servant or employee of the Government undertaking, then, notwithstanding anything contained in this section, any dispute of the nature referred to in sub-section (1) relating to the invention shall be disposed of by the Central Government conformably to the provisions of this section so far as may be applicable, but before doing so the Central Government shall give an opportunity to the patentee and such other parties as it considers have an interest in the matter to be heard.

CHAPTER XVIII

SUITS CONCERNING INFRINGEMENT OF PATENTS

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 the 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.

1[104A. Burden of proof in case of suits concerning infringement.—(1) In any suit for infringement of a patent, where the subject matter of patent is a process for obtaining a product, the court may direct the defendant to prove that the process used by him to obtain the product, identical to the product of the patented process, is different from the patented process if,—

(a) the subject matter of the patent is a process for obtaining a new product; or (b) there is a substantial likelihood that the identical product is made by the process, and the patentee or a person deriving title or interest in the patent from him, has been unable through reasonable efforts to determine the process actually used: Provided that the patentee or a person deriving title or interest in the patent from him, first proves that

the product is identical to the product directly obtained by the patented process.

(2) In considering whether a party has discharged the burden imposed upon him by sub-section (1), the court shall not require him to disclose any manufacturing or commercial secrets, if it appears to the court that it would be unreasonable to do so.]

Power of court to make declaration as to non-infringement.—(1) Notwithstanding anything contained in section 34 of the Specific Relief Act, 1963 (47 of 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—

(a) that the plaintiff has applied in writing to the patentee or exclusive licensee for a written acknowledgment to the effect of the declaration claimed and has furnished him with full particulars in writing of the process or article in question; and

(b) that the patentee or licensee has refused or neglected to give such an acknowledgment.

(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 2[after the publication

of grant of a patent], and references in this section to the patentee shall be construed accordingly.

Ins. by Act 38 of 2002, s. 43 (w.e.f. 20-5-2003).
Subs. by Act 15 of 2005, s. 57, for certain words (w.e.f. 1-1-2005).

106. Power of court to grant relief in cases of groundless threats 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—

(a) a declaration to the effect that the threats are unjustifiable;

(b) an injunction against the continuance of the threats; and

(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 1[existence] of a patent does not constitute a threat of

proceeding within the meaning of this section.

Defences, etc., in suit 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 one or more of the conditions specified in section 47.

2[107A. Certain acts not to be considered as infringement.—For the purposes of this Act,—

(a) any act of making, constructing, 3[using, selling or importing] a patented invention solely for uses reasonably related to the development and submission of information required under any law for the time being in force, in India, or in a country other than India, that regulates the manufacture, construction, 4[use, sale or import] of any product;

(b) importation of patented products by any person from a person 5[who is duly authorised under

the law to produce and sell or distribute the product],

shall not be considered as an infringement of patent rights.]

Reliefs in suits for infringement.—6[(1)] 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.

7[(2) The court may also order that the goods which are found to be infringing and materials and implement, the predominant use of which is in the creation of infringing goods shall be seized, forfeited or destroyed, as the court deems fit under the circumstances of the case without payment of any compensation.]

Right of exclusive licensee 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 earned by means of the infringement so far as it constitutes an infringement of the rights of the exclusive licensee as such.
Subs. by Act 56 of 1974, s. 3 and the Second Schedule, for “existing” (w.e.f. 20-12-1974).
Ins. by Act 38 of 2002, s. 44 (w.e.f 20-5-2003).

(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.

Right of licensee 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.
Restriction on power of court 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 proceedings 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.

[Restriction on power of court to grant injunction in certain cases.]—Omitted by The Patents

(Amendment) Act, 2002 (38 of 2002), s. 46 (w.e.f. 20-5-2003).

thereof.—1[(1) If in any proceedings before 2*** a High Court for the revocation of a patent under section 64 and section 104, 3, the validity of any claim of a specification is contested and that claim is found by 2 the High Court to be valid, 2*** the High 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 judgment in his favour, he shall be entitled to an order for the payment of his full costs, charges and expenses of an 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.

Subs. by Act 15 of 2005, s. 59, for sub-section (1) (w.e.f. 2-4-2007).

1[(3) Nothing contained in this section shall be construed as authorising the courts 2*** hearing appeals from decrees or orders in suits for infringement or petitions for revocation, as the case may be, to pass orders for costs on the scale referred to therein].

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.

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 for 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.
