I'll ask my colleague who interfaces with the telecom sector on a regular basis to respond to that.
Within the broad issue of these patents and 4G technology, there are a number of companies out there who are working on patents to develop the 4G generation of handsets and cellphones so that we can all do many more things on our BlackBerrys, cellphones, and so forth. Obviously, Nortel was one. However, as I think one of the Nortel people mentioned this morning, it's one thing to be getting kudos from the industry, but if your customers aren't buying, it's not commercializeable research.
