Nokia filed two separate revocation actions challenging Mala’s EP 2 044 709 patent, valid only in Germany. The first was filed on 29 April 2021 in the German Federal Patent Court but was unsuccessful, as the patent was upheld (appeal pending). The second was filed on 15 December 2023 in the Unified Patent Court (UPC). This article focuses on Mala’s objection to the UPC's jurisdiction, in which they argued that since a revocation action was already ongoing in Germany, the UPC should reject Nokia’s action as inadmissible.
