is mostly that it does not grant patents for trivial or frivolous applications that are not really inventions, such as amazon's one-click. If the UK patent office awards a patent, it's probably for a genuine invention rather than the bogus trash that the USA patent office accepts.

So above all, any changes to UK patent law should NOT result in the dilution of its present strengths. If it causes patents comparable to the present to happen faster, then fine -- but any weakening of its present diligence or any increase in the present scope would be a very bad step.

There'll still be the same amount of patenting going on, only bigger firms will of course pay the premium for "fast tracking", while smaller applicants will just get pushed to the back of the queue and receive a rubbish slow service.
