Jim - I'll say it again - not all IPR is created equal. At this point in time, without Qualcomm's patent on power control in a cell system, CDMA doesn't work in a mobile cell system. Period. That is not true of, for instance, 538.

First, 538 is a compendium of different, virtually unrelated, items. The only thing they all have in common is that they mention CDMA. And of the three disparate things in the patent, two are worthless. I practically guarantee it. On a scale with the GTE patent at 0 and the Qualcomm Power Control patent at 10, the two items are at 1 with an uncertainty of 1. (The two items are: 1-general discussion of the merits and trades involved in different methods of power control, 2-a completely obvious multiple banks approach to a multipath correlator)

The third item has to do with varying the bandwidth of a transmitted signal. It is certainly something I have never seen before nor would I have thought of it (although that doesn't necessarily make it original) and thus rates higher on the originality scale. However, I have doubts about its utility, so at best I give it 4 with uncertainty of 3.

Clark

PS My scale of 0 to 10 covers a lot of facets. To be a 10 a patent must not only be very likely to be found valid in court (i.e. original and non-obvious in an adversarial trial), it must also be useful in the real world. If it fails completely on any of these counts it is a zero even if everything else is perfect.

PPS Note that humorously the second most referenced patent author in 538 is Gillhousen(sp?). Guess where he works?
