Der patentrechtliche Verhältnismäßigkeitsgrundsatz im Bereich Arzneimittel und Medizinprodukte, Teil 2, PharmR 3/2023

With the Second Act on the Simplification and Modernization of Patent Law (2nd PatMoG), German patent law has undergone significant changes. In particular, in §139 (1) S.3 PatG a proportionality barrier with regard to the right to injunctive relief under patent law was codified. The first part of this article, which appeared in the last issue, focused on the history of these new provisions and the balancing of third-party interests. In the second part, Dr Marco Stief presents the other factors relevant for balancing and the claim for compensation according to §139 (1) S.4 Patent Act. Finally, an overview of central procedural considerations is given.
