ALR - Here are some recent NOK patents NOI intended, but I can find most of the Nokia patents myself. That is the easieist of the easy part. The harder part is sifting through them to find the valuable ones - it takes a dead minimum of 15 minutes to give even the most cursory evaluation to a patent, and more nominally an hour. Then, after sorting the list comes the hardest part; it can take 5 to 10 hours apiece to do a moderate analysis of each patent. Clark PS I spent a few hours today doing a few simple filters (i.e. to be taken with a medium large grain of salt), and even combined Nokia and IDC come out behind Ericsson, which in turn comes out way behind Lucent and Motorola, which, you guessed it, comes out behind Qualcomm. Odd that Motorola should have so much CDMA related IPR and still have such trouble with the chipsets/software. PPS I find it very interesting that when I first came to the Qualcomm thread it was relatively easy to determine which patents where Qualcomm's key patents. In contrast, IDC afficionados are still unable to point me to valuable CDMA patents and some to which I have been pointed haven't been worth much more than the paper they were printed on (IMO).
