The lawyers will be fine.
Instead of the UPC the UK will probably follow the US Patent methodology where anything can be patented (ideas, designs, art, etc.) with no burden of proof and completely ignoring any prior art or even the slightest inkling of common sense, and all disputes are sorted out in court at great expense. That way the lawyers will be able to afford Ferrari's and 2nd homes in St Tropez and only the rich/corporate will be able to afford to win. Cynical? Me?
