International Patent Filing in India FAQ
Does an International Patent Application filed under Patent Cooperation Treaty (PCT) designating India be treated as a patent application for grant of patent under the Indian Patent 1970 Act?
Yes, an international patent application filed under Patent Cooperation Treaty (PCT) designating India shall be treated as a patent application for patent under the Indian Patent Act if filed within 31 months from the earliest priority date of the patent application before the Indian Patent Office.
Will filing a patent application under PCT grant worldwide patent protection?
No, the Patent Cooperation Treaty (PCT) patent application doesn’t provide universal or worldwide protection for a claimed invention. The international patent application only provides interim way out to extend the time line for filing the patent application in other foreign countries. The time available under Paris Convention for securing priority of the patent application in other countries is 12 months from the date of initial filing. Under the Patent Cooperation Treaty (PCT), the time available could be as much as minimum 20 and maximum 31 months in case of India. Moreover, a patent inventor is also benefited by the international search report prepared under the PCT system to be sure that the claimed patent invention is novel and non-obvious to a person skilled in the art. The patent inventor can also select for preliminary examination before filing in other foreign countries to be very positive about the patentability of the claimed invention.
