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.

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.

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).
