Unified Patent Court Agreement under threat?

It had to happen: the xenophobic press has noticed (courtesy of Douglas Carswell MP, the sole UKIP member in the House of Commons, who has tabled an Early Day Motion) that however hard Brexit may be it presently does not involve trashing the Unified Patent Court Agreement. Now that the Daily Express is reportedly on the case (see Intellectual Asset Management's report - I could not bring myself to investigate that rag's website, still less to drive traffic to it), I don't give much for the Agreement's future. I am amazed that, after all the hard work creating the Agreement (and all the other good stuff that has come out of the EU - of which even its sternest critic, if apprised of the facts, would surely agree there is some, even if it's only compensation for delayed flights), anyone should think it is a good use of scarce resources to undo it all and recreate something new that probably won't look very much different. Although, of course, the Unified Patent Court, by definition, isn't something the UK could do by itself.
