Official legal text
The verbatim statutory text of this provision is reproduced from the official source and checked by our legal reviewer before it is published here. Until that check is complete for this page, read the exact wording directly from the official source linked below — it is the only version that governs.
Read this as a plain-language summary. If it and the official text, or a relevant Gazette notification, say different things, the official text and the notification are what count.
What this section says, in plain language
Section 7 sets the shape of a patent application. Its first rule is the one-invention rule: every application must be for one invention only. This keeps examination manageable and keeps the fee structure fair. If claims are later found to cover more than one invention, the answer is not refusal but division, and Section 16 provides for filing a further application to carry the surplus subject matter.
The second rule is formal. The application must be made in the prescribed form and filed at the appropriate office. In practice this means Form 1 as the request for grant, supported by the specification in Form 2, a declaration as to inventorship in Form 5 where a complete specification is filed, a statement and undertaking about foreign applications in Form 3, and a power of authority in Form 26 where an agent acts. Applicants claiming startup or small entity status file the evidence required for that status. The appropriate office is determined by the applicant's place of residence, domicile or business, or the place where the invention originated, and for foreign applicants by the address for service in India.
The third rule is about proof of right. Where the application is made by an assignee rather than by the inventor, the applicant must furnish proof of the right to make the application. This is where the assignment deed or the endorsement on Form 1 is produced. Rule 10 fixes the period, which is currently six months from the date of filing of the application, and the Controller can allow further time in appropriate cases. Confirm the exact period against the Rules in force, because these timelines have been amended more than once.
Section 7 also handles international applications. An application corresponding to an international application filed under the Patent Cooperation Treaty and designating India is treated as an application under the Act, and the complete specification filed under the Treaty is treated as the complete specification for Indian purposes. This is the statutory hook for the national phase, which is why national phase entry is a continuation of an existing application rather than a fresh filing.
Finally, an application must be accompanied by a specification, either provisional or complete. Where a provisional specification is filed, the complete specification must follow within the time allowed by Section 9. An application without any specification is incomplete, and a date of filing cannot properly be secured on nothing.
Why this section matters
Every applicant, Indian or foreign, individual or organisation, and every agent preparing a filing.
At the moment of filing, and again when the Patent Office issues formal objections about documents or proof of right.
The formal requirements that a valid application must meet, and the obligation on an assignee to prove entitlement.
Objections, avoidable delay, loss of the intended filing date, or in serious cases refusal for failure to establish the right to apply.
How it works in practice
A startup files as assignee and completes its proof
Sundara Weavetech Pvt Ltd, a five-person textile machinery startup in Coimbatore, files an application for a yarn tension sensor invented by its two engineers. The company files Form 1 as applicant, names both engineers as inventors, files the complete specification in Form 2, and claims small entity status with the required evidence. Because the engineers, not the company, are the true and first inventors, the company is applying as an assignee. The founders assume their employment letters are enough and file nothing further. Four months later the Patent Office issues a formal objection asking for proof of the right to make the application. The company executes a short deed of assignment from both engineers, has it signed and dated, and files it within the period allowed by Rule 10 along with the endorsed Form 1. The objection is dropped. Had the founders waited past the period, they would have had to ask the Controller to allow the filing late, adding cost and uncertainty to an otherwise clean file.

Key points to remember
- One application, one invention. Extra inventions are handled by a divisional application under Section 16.
- The application must be in the prescribed form and filed at the appropriate office.
- An assignee applicant must furnish proof of the right to apply, with the period fixed by Rule 10.
- A specification, provisional or complete, must accompany the application.
- A PCT application designating India is treated as an application under the Act, which is how national phase entry works.
- The appropriate office depends on the applicant's residence, domicile, place of business, or the place where the invention originated.
Common mistakes and misunderstandings
- Filing a single application covering several unrelated inventions to save fees. This produces a unity objection and forces a divisional later.
- Assuming that naming the company on Form 1 is by itself proof of the right to apply. A document showing the transfer from the inventors is what is asked for.
- Choosing the wrong appropriate office. Jurisdiction follows defined criteria, not convenience.
- Treating the national phase as a brand new Indian application. It is a continuation of the international application already on file.

Forms, deadlines and fees
The Second Schedule to the Patents Rules contains the prescribed forms. A form that has been amended will not match an older saved copy, so take a fresh download from the official site before you fill anything in.
- Where the applicant is an assignee, proof of the right to make the application must be furnished within the period fixed by Rule 10, currently six months from the date of filing. Check the Rules in force, and note the Controller may allow further time.

We do not publish fee amounts. The First Schedule sets them, and they differ by category of applicant, such as a natural person, a startup, a small entity or another applicant, and by the mode of filing.

Questions people ask about Section 7
What documents are needed to file a patent application in India?
A complete filing generally includes Form 1 as the application for grant, the specification in Form 2 as either a provisional or a complete specification, drawings where needed, Form 3 with the statement and undertaking about foreign applications, Form 5 declaring inventorship where a complete specification is filed, and Form 26 if a patent agent or attorney acts for you. Applicants claiming startup or small entity status file the supporting evidence. An assignee applicant must also furnish proof of the right to apply.
Can one patent application cover more than one invention?
Section 7 requires an application to be for one invention only. In practice claims that form a single inventive concept can be grouped together, and Section 10 allows a group of inventions linked so as to form one inventive concept. If the examiner finds the claims cover more than one invention, you do not lose the extra subject matter. You file a further application under Section 16 before grant, and it takes the date of the original application.
What is proof of right in a patent application?
It is documentary evidence that the applicant is entitled to apply where the applicant is not the inventor. It is usually a deed of assignment executed by each inventor in favour of the applicant, or an endorsement signed by the inventors on Form 1 itself. Employment agreements are sometimes accepted where they clearly assign the invention, but a specific assignment is safer. Rule 10 fixes the period for filing it, and the Controller may allow further time on request.
Which patent office should I file at in India?
India has four patent offices, at Delhi, Mumbai, Chennai and Kolkata, and each has a defined territorial jurisdiction. The appropriate office is decided by the applicant's place of residence, domicile or business, or the place from where the invention originated. For an applicant with no place of business in India, the address for service in India decides jurisdiction. Once an application is filed at the appropriate office, all subsequent proceedings on it are conducted at that office.
