Provisional Patent Application

Starting from INR 20,000 (USD 249.00)

To get the earliest possible priority date on your invention, you can file a provisional application. As a general rule, the priority date for your invention is the date on which you first filed a patent application that described your invention in detail.

A provisional application doesn't give you patent protection on its own (there are no 'provisional patents'), but it's useful in establishing an early priority date if you operate in a highly competitive industry where constant innovation requires you to get the jump on competitors.

A provisional application also gives you time to determine whether your invention is worthy of further time, money and effort associated with filing a complete application for a patent. It is also less expensive to file a provisional application than a standard complete application.

Complete (Non Provisional) Application

Starting from INR 40,000 (USD 499.00)

Every specification, whether provisional or complete, shall describe the invention and shall begin with a title sufficiently indicating the subject matter to which the invention relates. Every specification shall fully and completely describe the invention and its operation or use and the method by which it is to be performed.

We follow a comprehensive approach to encompass all aspects of the invention, including current and future designs and applications, ensuring complete protection.
