Patent Application Filing Procedure/Process in India

Filing a patent application in the Indian Patent Office is the first step towards securing a patent to your invention in India. To file a patent application, a set of forms has to be submitted to the patent office. The forms can be submitted online (http://ipindiaonline.gov.in/epatentfiling/goForLogin/doLogin) if you have a class 3 digital certificate. Alternatively, you can send true copies (hard copies) to the patent office. The patent office charges 10% additional fee if applications are filed offline.

 
Please note that, the most important factor in filing a patent application is preparing a patent specification. Drafting a patent specification is a highly skilled job, which can be only preformed by persons who have both techinical as well as patent law expertise. If a person or company is serious about protecting their intellectual property, it is highly recommeded to use the services of professional patent practitioners. To know more about this, you can read our article on this:
 
Further, we have provided this article for knowledge purposes only. It is recommened to avail services of professionals to file patent applications, as mistakes will prove costly. Thorough understanding of the Indian Patent Act is essential for filing patent applications. Patent agents have understanding of the Indian Patent Act and are the only persons (other than the applicant themselves) authorized by the Patent office to file patent applications on behalf of the applicant. InvnTree employs patent agents.

Indian Patent Filing Cost Calculator

 
It should be noted that Forms 1, 2, 3 and 5 can be submitted online. All forms of the patent office can be filed online.
 
An overview of each of the forms is provided below.
 
Form 1 – Application for Grant of Patent
 

 

As the name suggests, this form is an application for grant of patent in India. In this form, you will have to furnish information, such as, name and address of the inventor(s), name and address of the applicant(s), information corresponding to prior patent applications relating to the current invention, which you or any authorized entity has filed, and some declarations, among other information.
 
(Added after receiving comments from Mr. Naren) Please note that a local communication address (address in India) has to be provided. This point is of importance to foreign (Non-Indian) applicants.
 
Form 2 – Provisional/Complete Specification
 

 

Form 2 is used to furnish your patent specification. The patent specification can be provisional or a complete patent specification depending of the type of patent application (provisional or complete) you are filing. You might find our article on “What are the different patent filing options?” useful.
 
If you are filing a provisional patent application, then use the following preamble in the first page of Form 2:

The following specification describes the invention

 

On the other hand, if you are filing a complete patent application, then use the following preamble in the first page of Form 2:
 
The following specification particularly describes the invention and the manner in which it is to be performed

 

 
Note that, if you are filing offline, 2 copies of the patent specification has to be sent to the patent office. Additionally, count the number of sheets and claims (extra fee for more than 30 sheets and more than 10 claims) and calculate the appropriate fee. While counting the sheets, even the drawing sheets will have to be taken into account.
 
Form 3 – Statement and Undertaking Under Section 8

 

Form 3 is used to furnish information/actions relating to patent applications filed in other countries for the current invention. Additionally, any information relating to the rights corresponding to the present patent application has to be furnished. Further, you would be using form 3 to undertake that you will be keeping the patent office informed in writing the details regarding corresponding applications for patents filed outside India. You can read more about this in ourarticle.
Form 5 – Declaration as to Inventorship
 

 

This application is used to declare the inventors of the subject matter sought to be protected using the current patent application.
 
Form 9 – Request for Publication
 

 

If this form is not filed, then the patent specification will be published by the patent office after 18 months from the priority date (filing of the first patent application for the current subject matter). On the other hand, by filing this form, you can generally have your patent specification published within 1 month from filing this form. Note that the patent rights start from the date of publication of the patent application (enforceable after grant of patent).
 
Form 18 – Request for Examination of Application for Patent
 

 

This form can be filed within 48 months from the priority date. The patent office will not consider your patent application for examination unless this form is filed. Hence, if you wish to expedite the patenting process, filing of form 9 and 18 at an early stage is advised. A startup can also request for expedited examination of their patent application. The fee for this is INR 8000. At present, the patent office has limited this request to about 1000 request in a year.
 
As a final note, I would advise you to go through our article only for the purpose of gaining knowledge of the patenting process, not as a guide to file patents on your own, since this will lead to adverse affects at a later stage.
