how do you seperate what's more important between CDMA radio, power management, switching, handover, speech coding,etc etc. You keep changing the subject from important, still enforceable patents to 'important technology' - which isn't even remotely the question. Like it or not, there haven't been any really really big 'codec' breakthroughs - just a long evolution of little steps, with many completely in the public domain either due to expiration or academia. You think otherwise? - then find me a still valid patent that allows you to compress voice 2x better than any other technology that does not use the patent. Or find me a general compression system that gets just 1 db closer to the Shannon limit than any other patented system. They don't exist. Whereas it is clear that cellular CDMA allows about 3db improvement in capacity over anything else in a mobile wireless system - e.g. I haven't seen even an OFDM which doesn't use it. It is possible that in aggregate the patents in some other area are totally blocking even if individually they are not. E.g. if there were only 3 ways to get within 1 db of the Shannon limit and all three were individually patented the individual patents wouldn't be worth as much as the Q cellular CDMA patents - but in aggregate they would be. But I've seen no evidence of that. Clark
