By doing the inventor secures his idea for a year’s period. The provisional patent application provides a priority to an inventor or applicant and gives a time line of one year to present the complete invention details failing which the provisional patent application is lapsed and the applicant is not able to claim the idea.

Also known as non-provisional patent application or specification in India. The complete patent application is filed when an invention is completely developed and inventor has all the specific technical data pertaining to the invention. The complete patent application is either filed directly (if the inventor already possess all the technical details) or within one year of filing the provisional patent application. The complete patent application is filed with claims and sometimes with experimental details. It is always advised to the inventor to disclose all the technical know how in the complete patent application to achieve best patent coverage.

3) Patent Publication

The priority date is first filing date for the complete patent application, it can be a provisional patent application date or directly a complete patent application date.

The inventor can also chose to publish the patent application earlier than the stipulated time of 18 months by filing Form 9 in the Indian patent office.
