Drafting a patent application is an art in itself. Seeking the help of a patent professional will be a wise choice here. If you are in the initial stages of the research and development process, then it is best to file an optional preliminary application called provisional patent application.

Step 2: Preparation of patentability report: Authorized patent professionals or patent agents will then do an extensive research and prepare the patentability report, that contains the analyses based on the above-mentioned criteria.

Why provisional patent application is a good idea before filing the patent application

A provisional patent application secures your date and work. This means that none of your competitors can file for a similar invention once you file for a provisional patent application.

  • As India follows the first-to-file system, this ensures that the holder of the provisional patent would also be granted the permanent patent
  • There is a buffer time of 12 months to further develop your invention and to specify the complete details. The application gets abandoned upon expiry of 12 months of the application
  • The cost and resource involved for provisional patent application are less when compared to the permanent patent
  • The provisional specification helps you assess the market potential of your invention before taking the final plunge and filing a complete specification.
  • Once you are ready with your R&D and your invention’s detailed specifications, you can go in for a complete patent application.

Step 3: Publication of patent application: The application is then published after 18 months. A request to the early filing of application can be made along with a prescribed fee.

Please Note:

A. Patent Examination: would be a formal submission of a request for the patent examination that must be filed within 48 months from first filing the patent (provisional patent or complete patent). If failed to file within the time frame, per the Patent Act the application will be treated as withdrawn by the patent office. The examiner then conducts a comprehensive investigation and releases the first examination report called patent prosecution.

B. Patent objections: It is common that patent applicants receive objections, like “inconsistent or unclear claims”, “invention lacking novelty”, etc. Hence, it is mandatory to analyse the patent examination report and draft a proper response to the objections.

Grant of patent: Once all the patentability requirements are met, the patent grant notification will be published in the Patent Journal.
