Every Inventor who wishes to protect his/her intellectual property has to go through a maze of complexity
to file their patent application.
Patent filing requires a basic knowledge and proper documentation to deal with theprocedural
complications faced by thecommon man.But with accurate and proper legal guidance it can be made a
very simple process. This makes it possible for the inventor to monetize the patent/s and enjoy the
incentives of one’s intellect and pains which s/he endured to possess an intellectual property.
The formalities and documentation requirements by patent office are different depending upon the
specification laid by Indian Patent Office. Hence the conceptualization and identification process is to be
done very cautiously before initiating the patent application process. The very first and crucial
consideration is which type of patent you are filing for. There are 5 common types of Patent application
defined by the Patent Office, they are as mentioned below:
1) Ordinary Application:
An Ordinary Application is applied for granting a Patent without claiming any priority of application
made in the convention country or without any reference to any other application under
process.Ordinary Patent application can be filed by givingspecification in atechnical disclosure
statement relating to the invention and contains fields of inventions, prior art, objective and
summary of inventions, detailed description of inventions, drawing, claims and abstract containing
the summary of the invention. It can be filed either by a provisional (complete specifications can
be submitted within 12 months of filing of provisional application) or a complete specifications and
claims.
2) Convention Application:
A Convention Application is a patent filed in the patent office claiming a priority date basis the
same or substantially similar application filed in one or more convention countries.To have a
convention status the application is required to be filled within 12 months from the earliest priority
application.
This is specified in Section 135 of the Patent Act, 1970, claiming the priority date on which
application was filed, where applicant has already filed an application for grant of patent in a
convention country or countries.
3) PCT Application:
A PCT is an internationally recognized application, where you can file a single application to
protect your invention and is validated in 142 countries and it is governed by the Patent
Cooperation Treaty (PCT). The Application gets 30-31 months to enter into various countries from
the international filing date or the priority date, as applicable and therefore gives more time for
viability assessment of the invention.
It can be filed via Indian Patent Office acting as Receiving Office ,or with International Bureau of
the World Intellectual Property Organization (WIPO).It allows the applicant to make an informed
decision early in the patent process and amend changes as major expense are involved in
patent filing process and prosecution of the application in each country.

2. 4) Divisional Application:
A Divisional Application is an application when there ismultiple inventions containing a common
matter previously (the so- called parent application) filed for, by the inventor. It retains its parent
filing date even though the presences of multiple inventions are there. It is generally applicable in
cases where the parent application describes more than one inventionand is required to split into
more than one divisional application. In the United States, a divisional application is seen as a
type of continuing patent application (an earlier –filed patent application) where one or group of
closely related inventions are together.
5) Additional Application:
An Additional patent application is a modification or improvement of the main application for which the
inventor has already applied for or has obtained a patent. Often after filing a patent many
modifications, refinements and other additional uses of the invention resurfaces and the inventor
wants these additions to be patented too. In such cases there is no need to pay separate renewal fee
for these additions of patent for the duration of the patent and it also expires along with the main
patent, as the patent for the additions will be granted with original application.
