Section 6, 7(2) 54, 134, 135; Rule 10


(1)(a) If the Controller is satisfied with the claim 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 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.

Such a claim shall be made in Form 6 in the prescribed manner at any time before a grant of patent.

(b) 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.

(c ) The original assignment or agreement or an official copy or notarized copy thereof shall also be produced for the Controller’s inspection and the Controller may call for such other proof of title or written consent, as he may require.

(d) Further, the Controller shall not issue any such direction unless:

i. the invention is identified in the agreement or assignment by reference to the number of application for the patent, or
ii. there is an assignment/ agreement produced before the Controller by the person to whom it was made, indicating that the assignment or agreement relates to the invention in respect of which the application is made, or
iii. the rights of the claimant in respect of the invention have been finally established by decision of a court, or
iv. the Controller takes a decision after hearing the disputed parties as per the proceedings under section 20 (5) of the rules.

(2) Where one of two or more joint applicants for a patent dies at any time before the grant of patent, the Controller may, upon a request in that behalf made by the survivor or survivors, and with the consent of the legal representative of the deceased, direct that the application shall proceed in the name of the survivor or survivors alone.

Such request shall be made in Form 6 and shall be accompanied by proof of death of the joint applicant and a certified copy of the probate of the will of the deceased or letters of administration in respect of his estate or any other document to prove that the person who gives the consent is the legal representative of the deceased applicant.

(3) If any dispute arises between joint applicants for a patent as to 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 an opportunity to be heard to all parties concerned, 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.

Such application shall be made in Form 6 in duplicate and shall be accompanied by a statement setting out fully the facts upon which the applicant relies and the directions which he seeks. A copy of the application and statement shall be sent by the Controller to every other joint applicant.


Unlike many other Countries, Indian Patent Office functions from four locations viz. Kolkata, Delhi, Chennai and Mumbai for carrying out all procedures relating to patents.

An application for patent shall be filed with the Patent Office having appropriate jurisdiction. A territorial jurisdiction of patent office in respect of a patent application is decided based on any of the following:

i. Place of residence, domicile or business of the applicant (first mentioned applicant in case of joint applicants) or,

ii. Place from where an invention actually originated or,

iii. Address for service in India given by the applicant, when the Applicant has no place of business or domicile in India (Foreign applicants).

iv. Also, the further application referred to in section 16 of the Act shall be filed at the appropriate office of the first mentioned application only.

Territorial jurisdictions are as under:

Section 16, 74. Rule 4, 5.
