The inventor gets more 12 months to fully develop the invention and to file the complete requirements
• ORDINARY APPLICATION – An ordinary application for patent filed without claiming any priority either in a convention country or without any reference to any other earlier application under process in the office.
• CONVENTION APPLICATION – A convention application for patent filed with the intension of claiming a priority date based on the same or substantially similar application filed in one or more of the convention countries.
• PCT INTERNATIONAL APPLICATION – An Application filed in India under Patent Cooperation Treaty is an international application which can be filed in more than 150 countries by a single application.
• PCT NATIONAL PHASE APPLICATION – When an international application is made according to PCT designating India, an applicant can file the national phase application in India within 31 months from the international filing date or the priority date, whichever is earlier.
• PATENT OF ADDITION – When an invention is a slight modification of the earlier invention for which he has already applied for or has obtained patent, the applicant can go for patent of addition if the modification in the invention is new. One of the benefits of filing patent of addition is that there no need to pay 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 claims more than one invention, the applicant on his own may divide the application and file two or more applications, as the case may be for each of the inventions. The priority date for these applications is similar to that of the parent application.
