To me it seems more and more like these companies with their huge patent pools are bored and now play a game against each other.
company1: "Hey company2, I hold a patent vaguely describing what you do with product X"
company2: "Hey company1, I have two patents even more vaguely describing what you do with product Y"
company3: "Hey both of you, I hold ten patents that you both infringe on"
company1: "Oh yeah, well guess what, I have twelve other patents, that ..."
...Ad infinitum...
It's getting ridiculus...
