I don't know, in my view a patent troll is a company that managed to obtain a patent for something trivial that most people would not even think of obtain a patent for. For example: - displaying originating city/state based on area code of a calling number - swipe to unlock the phone - rounded corners and is trying to get money from anyone who uses it Typing through swiping is a bit more innovative. To be honest, I think there shouldn't be any patents on software. That field is thrives on building on top of work of others, and things change quickly, so patents are actually stifling innovation. At least if software patents can't be eliminated they should be much much shorter.
