Abstract

One way to achieve international patent protection is to file patents via the Patent Cooperation Treaty (PCT). The application process therein can be divided into two phases, those represented by chapters I and II of the PCT. According to the literature, patent applications filed via chapter II of the Treaty tend to be more valuable. The results presented in this paper suggest that in general this assumption is not justified. The analyses further revealed that for practitioners seeking fast patent protection at the European Patent Office (EPO) via the PCT, the choice should be chapter II of the PCT, with the EPO as preliminary examination authority.
