Filing of Patent Application

It is not necessary to visit the Patent Office to file the application, as an online filing facility is provided. Only in cases where the application is required to be filed offline, the same can be filed physically at the counter of the Office or can be sent by post to the Patent Office. Moreover, all communications by the office are made through emails.

A patent application can be filed with the Indian Patent Office either with a provisional specification or with a complete specification along with the fee as prescribed in Schedule I. In case the application is filed with a provisional specification, the applicant must file the complete specification within 12 months from the date of filing of the provisional specification. There is no further extension of time to file the complete specification after the expiry of the said period.

Patent applications can be filed through the comprehensive online filing system available at:

To register for filing of a patent application, the applicant can use a Digital Signature Certificate (DSC) or E-sign as per convenience. If the user wants to use DSC, the user is required to obtain a Class II/III digital signature without encryption from authorized vendors.

The user can visit the e-filing website where detailed information is available:

If the user wants to use E-signature, complete information is available under different tabs. The user will have to procure the E-sign from the authorized vendor using Aadhaar number or PAN number.

After obtaining the Digital Signature or the E-sign, the user can register on the Patent Office website by creating a user ID and password. The user can log in using these credentials.

After logging into the e-filing account, the user can select the required form, fill in the details, save the draft, and upload all relevant documents. The documents can then be digitally signed through DSC or E-sign.

After digitally signing the documents, they will appear under the "Payment" tab. The user can click on the payment tab and select the particular form to make payment. After successful payment, an acknowledgement receipt will be generated.

All previously drafted forms are available under the "Form History" tab and further under the "Drafted Forms" section. If a user discards any forms, they will appear under the "Discarded Forms" section.

Users can locate previously drafted forms using the specific date range filter. Users can also update their mobile number and email through the e-filing module under the "User Panel" tab.


Generally, in order to file an application, an applicant is required to file Form 1 which is a request for filing an application and Form 2 which is either a provisional or complete specification with drawings, if any. In addition to these, an abstract of the invention is also required. If the application is filed through a registered patent agent, a power of authority in favour of the said agent in Form 26 is also required. The application can be examined only after receipt of request for examination on Form 18/18A. The complete list of forms is available on the website www.ipindia.gov.in
