The Council of the EU has recorded here that Luxembourg deposited its instrument of approval of the Protocol on Privileges and Immunities (PPI) of the Unified Patent Court (UPC) with the Council’s General Secretariat on 3 April 2018.  The PPI will confer legal status on the UPC and certain privileges and immunities on the Court and its Registrar, Deputy-Registrar, judges and other staff to ensure its proper functioning.   Both the UPC’s Court of Appeal and Registry will be in Luxembourg, and Luxembourg is one of the four countries which must deposit their instruments of ratification, approval or accession in order for the PPI to come into force.  The other three countries are France, the UK and Germany.  France, which is hosting in Paris the seat of the UPC’s central division, deposited its instrument of ratification on 14 February 2018.   In the UK, which is hosting in London a section of the central division, the remaining piece of legislation enabling ratification was passed on 8 February 2018.  In Germany, which is hosting in Munich the other section of the central division, the parliament passed a draft law on 2 June 2017 enabling ratification but the law’s promulgation is on hold due to the case pending in the Federal Constitutional Court.
