What is PCT National Phase Entry in India?
India is one of the world's largest patent markets, and foreign applicants enter it through the PCT national phase. The deadline is 31 months from the earliest priority date and cannot be extended.
We file the national phase application, the declarations India requires (including Form 3 on foreign filings and, where needed, Form 5 on inventorship), request examination, and handle the First Examination Report, hearings and grant. Indian practice has specific requirements, such as Section 3(d) for pharmaceuticals and Section 3(k) for software, and we draft claim amendments with those in mind.
