chennaitrademark.com - National Phase application

Since December 7, 1998, it has become possible to designate India in PCT applications and to elect India in the demand for preliminary examination.

If India is a selected country in the PCT application by you and you have also chosen in the demand for preliminary examination filed within 19 months of the priority date, then the applicant should enter the national phase within 31 months from the priority date.

But, the time limit for national phase entry in India is only 21 months from the priority date, if the applicant does not select India in the demand for preliminary examination.
