Provisional and Complete Specification: Their Purpose

Basically, a patent specification serves the purpose of describing your invention. The main difference in the provisional and complete specification comes with the type of application you file. You can either file a provisional application or a complete application. However, the difference comes in Form 2 where you need to fill out the provisional and complete specification section. Of course, it depends on the type of application you are planning to file.

Provisional Specification

You should file a provisional application if your invention is still in the development stage. A provisional application allows you to secure a priority date for your application. Consequently, you get a 12 month period to file a complete application from the date of filing a provisional application.

You need not describe everything about the invention. Basically, just a simple description is enough. There is no need to include drawings or claims in a provisional specification. However, it is highly advisable to describe as much about the invention as possible. But, this’ll eliminate any doubts and you will have a stronger foothold in terms of the protection.

In conclusion, a provisional specification does not need to be very elaborate. The main idea of a provisional application is to secure a priority date.

Complete Specification

You should file a complete application when your invention is complete in a holistic sense. The complete application will enlist every single detail about your invention. From its components to its applicability, everything needs a precise description.

Basically, the more elaborate your description, the better your chances are of registering a patent. Therefore, inclusion of drawings is absolutely necessary and the claims need to be highly specific. Also, you must ensure that you clearly state the components of your invention, what its applicability is, and what its future scope is. Consequently, this will ensure that your IP rights are secure and safe.

If your specification is comprehensive, then it will discourage other entities from infringing/opposing your application at the time of publication.

Provisional and Complete Specification: Structural Differences

Chapter III, Section 10 of the Indian Patent Act explains how to structure the contents in a patent specification. Consequently, you must prepare a complete specification in a format as provided below.

  1. Title of the invention,
  2. Preamble,
  3. The field of the invention,
  4. Background of the invention,
  5. Objects of the invention,
  6. A brief description of the figures,
  7. Statement of the invention,
  8. An elaborate description of the invention,
  9. Claims,
  10. Abstract

A provisional specification also needs to follow a very similar format. However, it need not include the statement of the invention and the claims. Furthermore, the preamble also varies for a provisional and complete specification.
