The Patent Cooperation Treaty (PCT) is an international treaty with more than 150 Contracting States. It is administered by the World Intellectual Property Organisation (WIPO). The PCT makes it possible to seek patent protection for an invention simultaneously in a large number of countries by filing a single “international” patent application instead of filing several separate national or regional patent applications. With having more than 10 years of experience, we have served several law firms and corporates in filing PCT applications with a national or regional patent Office or WIPO.
