1st decisions on the merits issued by the UPC Central Division (1/2): what does the UPC say about the assessment of inventive step compared to the EPO?

Since the entry into force of the Unified Patent Court (UPC), one of the burning questions that practitioners have in mind is whether the UPC will apply the problem-solution approach of the European Patent Office (EPO) in its assessment of the inventive step. While it is still too early to draw any conclusions, it would appear from the decisions we have studied that the UPC applies its own standards, drawing inspiration from the EPO's problem-solution approach without duplicating it. We offer here a first analysis of how UPC assessed inventive step up to the recent decisions of the Central Division issued on 16 July (Sanofi v. Amgen and Regeneron v. Amgen ). A second publication will focus on the Central Division's decisions of July 19 (Meril v. Edwards Lifesciences ).

San-Ei v. Nexira on the abuse of the right to sue for infringement: an isolated case or the beginning of a disturbing case law for right holders?

the abuse of the right to sue for infringement : When it comes to infringement proceedings, it is common for the defendant to counterclaim for abuse of process, and equally common for the defendant to be dismissed. The dismissal of such claims is usually based on the grounds that the plaintiff may be mistaken about the scope of his rights and that the mere bringing of such action is not abusive per se.
