WIPO Patent Cooperation Treaty (PCT)

The PCT is an international treaty, administered by the World Intellectual Property Organization (WIPO), between more than 140 Paris Convention countries. The PCT makes it possible to seek patent protection for an invention simultaneously in each of a large number of countries by filing a single “international” patent application instead of filing several separate national or regional patent applications. The granting of patents remains under the
control of the national or regional patent Offices in what is called the “national phase”.

PCT applicants generally pay three types of fees when they file their international applications:

  1. International filing fee of approximately 1,450 US dollars (depending on the applicable exchange rate),
  2. Search fee, which can vary from approximately 410 to 2,400 US dollars, depending on the International Searching Authority chosen, and a
  3. Small transmittal fee which varies depending on the receiving Office.

A 90% reduction on the international filing fee, the supplementary search fee and the handling fee applies to nationals of LDCs and residing in an LDC. If there are several applicants, each must satisfy those criteria. For more details, including the list of the PCT Contracting States the nationals and residents of which are eligible for such fee reductions, please refer to: Applicability of 90% Reduction in Certain PCT Fees.
