I recently mentioned the patent troll site link here. To give you a sample of its work, here is a paragraph posted today on patent suits filed and the number brought by trolls:

"Here are the cumulative statistics for the first 11 months of 2007, comparing the various districts. Note that I got an email from someone who had numbers run independently, and I am told I have undercounted the number of cases by X and the number of defendants in EDTX by Y. As I said above, this is really a judgment call. I may not have counted all of the bifurcated Judge Clark cases while someone else may have. Either way, even if my numbers are low, they are astoundingly high compared to history:

"ED Texas: 343 patent cases, 1,320 defendants sued (140 troll cases)

CD California: 251 patent cases, 647 defendants sued (17 troll cases)

D New Jersey: 176 patent cases, 329 defendants sued (13 troll cases)

D Delaware: 128 patent cases, 310 defendants sued (16 troll cases)

ND California: 127 patent cases, 240 defendants sued (19 troll cases)

ND Illinois: 125 patent cases, 231 defendants sued (23 troll cases)

SD New York: 95 patent cases, 244 defendants sued (13 troll cases)"
