Section 7 explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Section 7 sets out what a patent application must look like. It must be for one invention only, in the prescribed form, filed in the patent office; it must name the inventor and say the applicant is in possession of the invention; it must be accompanied by a specification; and an assignee must prove the right to apply. It also deals with applications under the Patent Cooperation Treaty that designate India. Getting these basics right is the first step of any patent drafting and filing exercise.
Every application is for one invention only, in the prescribed form, filed in the patent office (7(1)). An international application designating India is deemed an application under this Act if a corresponding application is also filed before the Controller in India (7(1A)), and its filing date is the international filing date (7(1B)). An assignee furnishes proof of right (7(2)). The application names the inventor and states the applicant is in possession of the invention (7(3)), and carries a provisional or complete specification (7(4)).
Section 7(1): one invention, prescribed form, filed in the patent office
"Every application for a patent shall be for one invention only and shall be made in the prescribed form and filed in the patent office."
- One invention only. Two unrelated inventions need two applications. Where an application does include more than one, section 16 allows division; see our post on the divisional application.
- Prescribed form. The form is fixed by the Patents Rules, 2003, which are not part of the text consulted for this article. We name no form number or fee.
- Filed in the patent office. "Patent office" includes any branch office (section 2(2)(b)).
Section 7(1A): PCT applications designating India
"Every international application under the Patent Cooperation Treaty for a patent, as may be filed designating India, shall be deemed to be an application under this Act, if a corresponding application has also been filed before the Controller in India."
Here the word "if" does the work. An international application that designates India is treated as an Indian application only if a corresponding application has also been filed before the Controller in India. Merely designating India in the treaty filing is not enough on the text. Inserted by the 2002 Amendment Act, with effect from 20-5-2003. The Act does not say in this sub-section when the corresponding Indian application must be filed; that is for the Rules, and we state no period.
Section 7(1B): the filing date
"The filing date of an application referred to in sub-section (1A) and its complete specification processed by the patent office as designated office or elected office shall be the international filing date accorded under the Patent Cooperation Treaty."
So for such an application, the date is not the day the Indian filing was made but the international filing date. This sub-section was inserted by the 2005 Amendment Act, with effect from 1-1-2005. Our post on PCT national phase entry in India explains how the two steps fit together.
Section 7(2): proof of right where the applicant is an assignee
"Where the application is made by virtue of an assignment of the right to apply for a patent for the invention, there shall be furnished with the application, or within such period as may be prescribed after the filling of the application, proof of the right to make the application."
Flag: "filling" in the printed text is a typographical slip for "filing". The meaning is clear.
This links back to section 6(1)(b), where an assignee may apply. If you apply as assignee, you either hand in the proof with the application or within the period the Rules prescribe. The Act does not say what counts as proof, and gives no period.
Section 7(3): possession and the inventor's name
"Every application under this section shall state that the applicant is in possession of the invention and shall name the person claiming to be the true and first inventor; and where the person so claiming is not the applicant or one of the applicants, the application shall contain a declaration that the applicant believes the person so named to be the true and first inventor."
Three requirements:
- A statement that the applicant is in possession of the invention.
- The name of the person claiming to be the true and first inventor.
- If that person is not an applicant, a declaration that the applicant believes the named person to be the true and first inventor.
The word "person" in the second requirement was substituted for "owner" by the 2005 Act (with effect from 1-1-2005). The text before 2005 spoke of the "owner" as the one named; the present text speaks of the "person" claiming to be the true and first inventor.
Section 7(4): the specification
"Every such application (not being a convention application or an application filed under the Patent Cooperation Treaty designating India) shall be accompanied by a provisional or a complete specification."
An ordinary application needs either a provisional or a complete specification. Convention applications and PCT applications designating India are carved out of this sub-section. The difference between the two types of specification is the subject of section 9; see our article on section 9 and the post on provisional versus complete specifications. This sub-section was substituted by the 2005 Act.

Worked example
Example. Kiran Agro Tech Pvt Ltd wants to protect a fictional seed-coating machine and a separate, unrelated drone-spraying nozzle that two of its engineers also developed. Under section 7(1), each is a different invention and needs its own application. The machine was developed by Meenal Shah, who assigned her right to apply to the company. The company files as assignee, names Meenal as the person claiming to be the true and first inventor, states that it is in possession of the invention and, because Meenal is not an applicant, includes a declaration that it believes her to be the true and first inventor. Because the company applies by virtue of an assignment, it furnishes proof of the right with the application or within the prescribed period. The application is accompanied by a provisional or a complete specification.
What section 7 does not say
- It does not fix any fee, form number or time limit; the Rules do.
- It does not describe the contents of a specification; that is section 10.
- It does not say how many inventors can be named.
- It does not say what the patent office does if one invention requirement is breached; sections 16 and 17 and the Controller's powers deal with that.
