I will start, and maybe Albert can follow.
I don't have particular statistics at my fingertips on either of those things. What I think I could say, though, is that the first patent box I believe was in Ireland, probably about 20 or 30 years ago. It has been replicated in a number of European countries since that time. The latest I'm aware of is the U.K. just in the last year or two.
Sometimes imitation is the best form of flattery you can get. It's good evidence that it must be working. Otherwise, why would a whole bunch of other countries be doing it? I think that's a very key fact.
