Just quickly, there are actually a number of issues that emerge. The first one is actually that IP, whether you're fighting China or anybody else, is a real issue. Everybody today is reverse-engineering. If you actually patent, you in a sense give them a step up to do that, because you teach them how you're doing what you do now, and they'll find another way to do the same thing, even if they respect your IP. It's a very competitive world.
In working with China, we've been concentrating on know-how rather than the patentable kind of IP. A classic example of that is a material we've developed here, which Toko is now building a $300 million facility to produce. It produces a core material that will actually be sent to China, where they will add value to it, but they won't be able to really replicate the mill or the know-how of how to produce this particular product. In our view, it's very unlikely that will happen.
So part of it is the way you do the deals too. I would agree, though, that you'd never want to give up on aggressive positioning with respect to counterfeiting and avoiding of IP. You just have to keep on in that case.
