Procedure for filing a Patent application in India
- PCT International Application – An application filed under PCT which is an International filing system where the applicant gets an international filing date in the designated countries and later it enters the national phase (31 months from the priority date).
- Procedure of filing PCT International application – An International application can be filed with any of the Indian Patent office i.e Kolkata, Mumbai, Delhi, and Chennai as receiving office or with International Bureau of WIPO as receiving an office. The International application consists of the request form, description with one or more claims and one or more drawings (if required) and an abstract. The application should be in a language that is either ( English, Chinese, French, German, Japanese, Spanish, Russian or Arabic). The International application in triplicate with the requisite fees should be filed with the receiving office, which sends one copy of the International application to the International Bureau as “ record copy” , another copy to International Searching Authority as “search copy” and keeps one set of the application with itself as “ home copy”.
- Note – ” Residents of India have to take prior permission from the Government before filing an application outside India under section 39 due to security reasons, mainly to determine if the invention relates to defense purposes. This is done by filing Form-25 with the appropriate fee to seek permission from the government or otherwise an application for the same invention has to be filed in India six weeks prior filing of it outside India.”
- PCT National Phase Application – An International Application filed under the PCT designating India, enters the national phase within 31 months from the priority date of International application or filing of the International application whichever is earlier.The National phase application in India consists of the Forms prepared according to the Indian Patent Act and the same specification as filed in the International Application.
- Convention – Application Types of Patent Application Filings in India- When an application is filed by an applicant in India within twelve months from the priority date claimed for the same invention filed in two or more convention countries is called convention application.
- Ordinary Application – An application which does not claim any priority of an application made in a convention country or any other application is called an ordinary application.
- Divisional Application – An application made any time before the grant of the Patent, which is generally filed to obviate the objection of a unity of invention in examination reports, issued by the examiners of the Indian Patent office is called Divisional application. When the claims of an invention relating to more than a single invention then, in that case, a divisional application can be filed, which has the same specification as of the parent application but the different set of claims.
- Application for Patent of Addition – If there is any modification or improvement in the invention for which the applicant already has the patent or has already filed the application for a patent, then he may file a patent of addition application. Provided that the date of filing of a patent of addition application should be same or later than the filing date of the main invention. There is no separate renewal fee for Patent of Addition application unless it is made an independent application. Patent of Addition will not be granted before the granting of the patent of the main application.
