Portuguese Patent | European Patent | International Patent | Utility Model

It is not a patent grant procedure but a unified patent filing procedure that covers states from all over the world. It allows the postponement of the costs of national applications in the different states until the 30th month from the application or priority date. One of the possible designations is the European patent. It includes two phases: the international phase and the national phase. The international phase includes a formal examination and a Search Report, both mandatory, and an optional in-depth examination.

The national phase is equivalent to a single application in each designated state, with the advantage that it has already been examined during the international phase. The yearly maintenance fees are to be paid during the national phase in the different states.
