Brexit and the EU Patent - Part II: what shall we do?

In my first article (GRUR Int. 2017, 301 and Journal
of Intellectual Property Law & Practice (2017) 12 (6):
516-525) I reached the conclusion that, after and because
of the withdrawal of the UK from the European
Union, the entire Patent Package, including the
UPCA (the agreement on the UPC), will become inapplicable
to the UK. In this new paper I propose a possible
way to have the Patent Package entering into
force, notwithstanding the withdrawal of the UK, but
without the participation of this country.
