What is an international patent?

An international patent is a type of patent that is recognized throughout the world. It is also known as a “patent of addition” or a “PCT patent.” International patents are authorized by the World Intellectual Property Organization (WIPO), a specialized agency of the United Nations. International patents are granted on the basis of a single application filed in any of the member countries of the Patent Cooperation Treaty (PCT). This application is examined by the International Searching Authority, who then issues an international search report as well as an opinion on the patentability of the invention. The applicant then has the option to enter the national phase or regional phase in any member countries of the PCT, or to abandon the process. In Washington, international patents are protected under the Patent Cooperation Treaty Implementation Act of 1984. This legislation implements the Patent Cooperation Treaty and directs the US Patent and Trademark Office (USPTO) to be the International Searching Authority for the United States. It sets out the procedures for requesting and granting international patents, and provides penalties for violations of the treaty. International patents provide inventors with protection for their inventions across multiple countries. It is an important tool for businesses to protect their Intellectual Property and ensure that their inventions are not copied or used without permission.
