NPR: This American Life did an excellent episode about patent trolls where they cover east Texas and what it is about it that makes it so lucrative to file the suit there. Here is the episode transcript: http://www.thisamericanlife.org/radio-archives/episode/441/t... The audio of the show can be listened to there as well. Apologies on not giving a summary. I normally would, but it has been a while since I listened to it and I don't want to misrepresent it.
