International Patents: Myth and Fact

There is no such thing as an International Patent. Patents are granted by individual countries. The only international patent organization is the World Intellectual Property Organization (WIPO). WIPO only publishes patent applications, called PCT Request. The PCT Request is a request under the Patent Cooperation Treaty. The purpose of this is to extend filing time in foreign countries. The phrase International Patent can sometimes be used to refer to the PCT Request, and, sometimes it means that someone is confused.
