Is a patent valid in every country? Patents are territorial rights. In general, the exclusive rights are only applicable in the country or region in which a patent has been filed and granted, in ance with the law of that country or region.
Submit the application to the World Intellectual Property Organization (WIPO) or a national patent office. Your invention is then provisionally protected in all contracting states of the Patent Cooperation Treaty (PCT). The WIPO carries out a search on the state of the art (also known as the prior art).
General Format: Inventor1, Inventor2, et al. Title of patent. Patent number (include country code, the word “Patent”, and patent number with retained commas), date of filing (format Month Date, Year), and issued date of publication (format Month Date, Year).

European patents are given the same number, but with B1 at the end instead of A. International applications (see page 5 for an explanation of what these are) have the publication format WO X/Y AZ, where WO stands for “World”, X is the year of publication and Y is a serial number recommencing each year.
The standard number format for searching for PCT applications in the Register consists of the WIPO code WO followed by the year of filing (four digits), the country code of the country (two characters) and a five-digit serial number, adding up to a fixed length of 13 characters. For example: WO2007IB51010.
Although the WO designation itself does not confer patent rights, it simplifies the process by offering a common standard across the 184 PCT member countries, including the U.S., China, and European nations.
In 1861 the seven-year extension was eliminated and the term changed to seventeen years (12 Stat. 246, 248). The enactment of the 1994 Uruguay Round Agreements Act then changed the patent term from seventeen years from the date of issue to the current twenty years from the earliest filing date.
A WO patent is granted by the World Intellectual Property Organization, or WIPO. The prefix WO, which is short for WIPO, indicates that the patent will be administered by this body. In general, the protection conferred on an invention by patent law will only extend to the country or territory in which it is patented.
