Denmark might be joining the Unified Patent Court within the next few months:

According to the newspaper Berlingske Tidende the Danish Government has included a bill in its legislative proposals to join the Unified Patent Court. The Minister for Trade and European Affairs, Nick Hækkerup declared about the bill that “(the) roadmap is to publish (the government’s proposals) and argue why the parliament should support this. It’s so obviously in our interest because it would also protect the inventions that are being made in Denmark”. It will not however be straightforward for Denmark to join the UPC. In fact because Denmark has an opt-out from EU legislation on Justice, if more than 80% of its MPs decide to vote against the bill, the Danish government will need to call for a referendum.
