PCT National Stage Filing in India: Know the Facts


India as one of the top 5 economies and soon to be the third largest economy, is a crucial player for national-stage PCT filings for any corporate or startup.

To secure patent protection in India as national phase entry via the PCT route, applicants must file in India by following the regulations set forth in the Indian Patents Act. Unlike many other countries, the Indian Patent Office (IPO) does not permit substantive amendments while filing the national phase, except for deleting claims.

National stage filing requirements in India

The process of filing a PCT application in India involves adhering to specific requirements outlined by the Indian Patent Office (IPO). For a PCT application in India, submissions must be in English or Hindi, the official languages.

To secure a filing date, the Indian Patent Office requires:

  • You need to file the national stage by 31 months
  • A full specification comprises a description, claims, abstract, and drawings in either English or Hindi as per the PCT filing
  • You need a address of service in India.(Address of patent agent for nonresident applicants)
  • Priority claim particulars: date, application number, and country
  • Payment of the prescribed filing fee
  • Notarized Power of Attorney (POA) is must for agent filing

Meeting these requirements accurately and promptly is essential to successfully initiating the PCT national phase in India.

Examination Filing Timeline

As of now the timeline for filing examination of a national phase patent application in India is 48 months from the priority date or date of filing the international application. In future your timeline will reduce to 31 months from the priority date or filing date.
