In an earlier blog, we outlined that the UK confirmed its intention to ratify the International Agreement on a Unified Patent Court. In December 2016, the UK government proceeded to sign the Protocol on Privileges and Immunities of the Unified Patent Court.  The Protocol provides EU privileges and immunities to the judges of the Unified Patent Court necessary for the exercise of its functions.  The Protocol is required in the individual countries hosting divisions of the court, one of which is in London.  This positive step would suggest that the UK is moving closer towards ratification.
