An ordinary application must be accompanied with a complete specification and claims.

In order to get convention status, an applicant should file the application in the Indian Patent Office within 12 months from the date of first filing of a similar application in the convention country.

  • Provides an option for requesting an International Preliminary Examination Report, the report containing an opinion on the patentability of the invention.

PCT National Phase Application

Patent of Addition

When an applicant feels that he has come across an invention which is a slight modification of the invention for which he has already applied for or has obtained patent, the applicant can go for a patent of addition if the invention does not involve a substantial inventive step. There is no need to pay the separate renewal fee for the patent of addition during the term of the main patent and it expires along with the main patent.


Divisional Application

When an application made by applicant claims more than one invention, the applicant on his own or to meet the official objection may divide the application and file two or more applications, as applicable for each of the inventions. This type of application, divided out of the parent one, is called a Divisional Application. The priority date for all the divisional applications will be the same as that claimed by the Parent Application (Ante-dating).
