The exchange that I proposed did not concern patents but copyright, a digital content right called the digital copyright exchange. Copyright, of course, unlike patent, is an unregistered right in Europe.
The idea here is to get a better quality of data into the marketplace, essentially so that markets in digital content work better, so that prices can be struck and deals can be made more readily. I would certainly see that as being an international phenomenon. There's work going on in a number of countries that I'm aware of on projects that bear some similarity to the idea that I've advanced in the review for the U.K.
