Deciphering the PCT Application Process
While there is no such thing as a world-wide patent, there is something that approximates a world-wide patent application that can result in a patent being obtained in most countries around the world. This patent application is known as an International Patent Application, or simply an International Application. The international treaty that authorizes the filing of a single patent application to be treated as a patent application in countries around the world is the Patent Cooperation Treaty, most commonly referred to as the PCT.
What is the Patent Cooperation Treaty (PCT)?
The PCT is an international treaty with more than 150 Contracting States. 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. The granting of patents remains under the control of the national or regional patent offices in what is called the “national phase”.
