This calls into question the way in which the \u2018long arm\u2019 is being applied with regard to European patents validated in States that are not party to the Agreement on a Unified Patent Court (UPCA), whether or not they are members of the European Union, since no counterclaim for revocation or plea of invalidity as a defence can be filed or raised with regard to such patents. This raises significant doubts about the compatibility of how the \u2018long arm\u2019 is applied in the Unified Patent Court system, given its own Rules of Procedure.<\/p>\n\n\n\n<div
