UPC is the result of pan-European efforts, in which we find here and there traces of one system or another. This also implies potentially dangerous consequences, which is likely to give rise to a number of difficulties: what about cases in which the UPCA’s provisions diverge from those of the national laws in question? Let’s take the example of article 25 of the UPCA: export does not constitute an act of infringement. This is also the case in German national law for instance (Sec. 10 of the Patentgesetz). On the contrary, in France, export constitutes an act of infringement (art. L. 613-3 of the French Intellectual Property Code). Which law should prevail in this case for acts committed in France? The UPCA regulation should certainly prevail, by virtue of the direct applicability of European regulations. However, the scope of such applicability is uncertain. Should the UPCA regulation apply only to unitary patents, or also to non-unitary European patents and national patents? In principle, as surprising and even shocking as it may seem, national titles should not be affected. Articles 24, 25, 26 and 29 of the UPCA refer to a “patent”, which is defined in Article 2(g) as a European patent or a unitary effect. On the other hand, the national patent, which is referred to in article 29, is distinguished and the Agreement is not intended to apply to it. However, in both cases, we are the owners of an invention, in other words, the right of ownership of the invention remains identical, even if the title recognizing this right is different. Is this not a breach of the principle of equal treatment under European law (article 21 of the Charter of Fundamental Rights of the European Union and article 2 of the Treaty on European Union)? For sure, we’ll have some complicated discussions here, such as: what about export to a country outside the Agreement (i.e., UK), in this case does export nevertheless constitute an act of infringement under French law or not? Does it depends on the type (EP/ unitary EP or FR) of patent you invoke, or not?
