"A troll is simply someone who has patent property rights who has the gall to enforce those rights"
No a patent troll is someone who has patented an idea (usually something obvious) and then proceeds to threaten anybody who tries to make something to extort money from them.
There one patent lawyer who's whole existance is working out where technology is heading and patenting the ideas before someone makes it happen. He's a lawyer. He invents nothing. He earns around millions every year because for most companies, it's cheaper to "licence" it than to fight him.
The problem is now, that there is so many trolls all wanting a cut that there is little left for inventors.
The problem is the patent office hands out patents like lollies and it costs a fortune to fight it. Yes you may well win the fight but if the fight will cost you a million and licencing it will cost you $100K, do you fight? If you fight, will you get your costs back? No you won't. Trolls make nothing and the patents are owned by $2 shell companies with no assets. You win and the shell company vanishes leaving you with squat.
Problem is you end up feeding the trolls cause it's cheaper than fighting them and the real problem is now that there are so many trolls you can't afford to feed them all.
I've been there. I fought. I won. I lost a stack of money even thought I won
