Luxembourg’s law approving the Protocol on Privileges and Immunities (PPI) of the Unified Patent Court (UPC) was published yesterday in the Mémorial (the official journal) here, and it comes into force on 18 March 2018. Luxembourg will then be in a position to deposit its instrument of approval with the General Secretariat of the EU Council.  As reported here, 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.
