I’m a bit confused, at this point, as to why patent trolls so often aggressively and confrontationally respond to companies that are aggressively unwilling to settle. It has a strongly increasing risk for the troll of getting the patents invalidated, and destroying their ability to get future settlements from the same patents. Even before this, it gets the troll in the spotlight, and lets other companies know that someone is fighting the patent. Keeping a low profile, and going after the (many) companies that are willing to settle without a fight would seem much more profitable.
It seems a bit like running a 419 scam, except instead of moving on to the next potential victim when someone emails back that they have the means to get you arrested, sending them your real information and telling them to go ahead and try. Sure, they might be bluffing, but is it really worth the risk when there are so many easy targets?
