The Patent Cooperation Treaty (PCT) is a multilateral international treaty, administered by the World Intellectual Property Organization (WIPO). The PCT facilitates the obtaining of protection for inventions where such protection is sought in any or all of the PCT Contracting States. It 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.

The PCT procedure consists of two main phases, the "international phase" and "national (or regional) phase".

Detailed information about international patents and the PCT is available on the WIPO website.
