Information about PCT National Phase Patent in India

PCT stands for the Patent Co-operation Treaty. The PCT system facilitates the filing of one patent application to be effective for all countries and provides for a simplified procedure for the search and examination of such applications. This allows a resident or national of a PCT member state to obtain the effect of patent filings in all the PCT countries and to defer the bulk of filing costs usually due on filing. Since December 7, 1998, it is possible to designate India in PCT applications and to elect India in the demand for a preliminary examination.

If India is a designated country in the PCT application, then the deadline for entry into the National Phase in India is 31 months from the earliest priority date. If the applicant does not so elect India in the demand for preliminary examination, then the deadline for entry into the National Phase in India is 21 months from the Priority Date. Therefore, all applicants who have designated India in their PCT application filed on or after December 7, 1998, will be able to file PCT National Phase applications in India.

The procedure under the PCT has great advantages for you as an applicant, for the patent Offices, and the public:

1. You have up to 18 months more than if you had not used the PCT to reflect on the desirability of seeking protection in foreign countries, to appoint local patent agents in each foreign country, to prepare the necessary translations, and to pay the national fees.
2. You can rest assured that, if your international application is in the form prescribed by the PCT, it cannot be rejected on formal grounds by any PCT contracting state patent Office during the national phase of the processing of the application.
3. Based on the international search report and the written opinion, you can evaluate with reasonable probability the chances of your invention being patented.
4. You have the possibility during the optional international preliminary examination to amend the international application and thus put it in order before processing by the various patent offices.
5. The search and examination work of patent Offices can be reduced or eliminated thanks to the international search report, the written opinion, and, where applicable, the international preliminary report on patentability that accompanies the international application.
6. Since each international application is published together with an international search report, third parties are in a better position to formulate a well-founded opinion about the potential patentability of the claimed invention; and
7. For you as an applicant, international publication puts the world on notice of your application, which can be an effective means of advertising and looking for potential licensees.

Ultimately, the PCT:

brings the world within reach,
postpones the major costs associated with international patent protection,
provides a strong basis for patenting decisions; and
is used by the world’s major corporations, research institutions, and universities when they seek international patent protection.
