In terms of Section 9 of the Indian Patent Act, 1970, a patent application can be filed with a provisional specification to secure the novelty of the invention, the immediate advantage of a provisional specification is that the invention becomes safe at least from the point of view of leakage of information. However, the applicant must file the complete specification of the invention within 12 months of submitting the first application for patent with the provisional specification.
However, in case the Inventor is ready with its invention in the form of a new product or industrial process, then the application for the grant of the patent must be filed with complete specification.

Types of patent specifications (Section 9 of the Patent Act, 1970)

  1. Provisional Patent Specifications

The provisional specification is filed when the invention is not complete, and the research and development are midway, and the Inventor wants to protect the novelty of the invention. In other words, the provisional specification is the first disclosure before the controller of the patent by way of making a formal application in the prescribed manner. The complete specification is filed when the research and development are complete, and the product or the process is fully developed and is ready for mass production or usage.

The patent application can very well be submitted with complete specification at the very first stage provided the Inventor is ready with its invention. However, it is an excellent method to ensure the secrecy of the invention if the same is still at the stage of research and development. You should understand that the provisional application does not mean filing a patent application with just rough details, but it defines the scope of the invention.
The complete specification should be closely related to what is in the provisional specifications. The filing of the complete specification does not erase the provisional specification filed earlier. It remains there all the time, and the examiner refers to the provisional specification also while examining the patent application. Hence the drafting of the provisional specification is of equal importance.
