> one of the main reasons that patent trolling is so successful is that the cost of settling is smaller even than the cost of winning a suit. Is the underlying reason for this strategy the low costs of settlement, or the extremely high costs of lawsuits? What if the value of a patent really is only a few thousand dollars? Note that this very tactic is used by big companies to avoid licensing valid and useful patents…
If you know you have a valid case (you aren't a troll), how hard would it be in practice to find someone to front the money for a lawsuit? Or for that matter, could you go to the competition and sell your patent? That is, say Apple's infringing on my patent; will Samsung buy the patent from me for a fair price and then sue Apple?
This isn't common. See Jarg corp which was basically out of cash, then hired lawyers on contingency (with patents licensed from Northeastern University) then sued google. I think google paid northeastern in a settlement.
