The PCT System (see the following figure) is a patent “filing” system, not a patent “granting” system. The PCT System provides for an international phase comprising filing of the international application, international search and written opinion of the International Search Authority, international publication and international preliminary examination. The PCT System also provides for a national/regional phase. The decision on granting patents is taken by national or regional Offices in the national phase.
