It's a difficult question to answer. We already have the right to use the patents we have the licence to. If new patents came up that we thought were strategically important, I guess we would have to look at those.
I guess buying a patent means you can cross-license to somebody else. But again, because these technologies are built on such open standards and there are so many big companies working in these technologies, developing this intellectual property--not just the people who are developing the networks, like Ericsson, but the handset manufacturers, and how they work with the open standards--it is really to the benefit of the industry to keep licensing as open as possible, to cross-license.
So I guess there are a lot of conditions around it that we would have to consider before we'd say we have to go in and buy that licence. I mean, if we could just license on a non-exclusive basis, that would probably be the tack that would be the most--
