Portugal Becomes the Eighth State to Ratify the Agreement on the European Union’s (EU’s) Unitary Patent Court (UPC)
The agreement on the UPC was signed on 19 February 2013 by all of the EU's member states, except Croatia, Poland and Spain. Portugal became the eighth state (after Austria, France, Sweden, Belgium, Denmark, Malta and Luxembourg) to ratify the agreement on 28 August 2015 (see here).
The agreement will not enter into force until the three biggest validation states, namely the United Kingdom (UK), France and Germany, ratify the agreement. France has already ratified, but the UK and Germany have not yet.
