What is a ‘patent troll’?................
Patent troll is a pejorative term used for a person or company that enforces its patents against one or more alleged infringers in a manner considered unduly aggressive or opportunistic, often with no intention to manufacture or market the product. A related, less pejorative expression is non-practicing entity (NPE) which describes a patent owner who does not manufacture or use the patented invention.[1]
Best simple description: a patent holding company.

I thought it was a person who illegally fills a White House position, but I could be wrong.
