I believe that a lot of you that complain about patent trolls have spare bedrooms that you aren't using for anything but storage. Just because you don't use the bedroom should some bum be able to move in and complain that he is entitled to live there just because you aren't using the room? It is the same with patents. Inventors and other R&D entities spend years and pay thousands of dollars to invent new products, both hardware and software. Often they have their products copied by the very companies they try to license to, those companies betting that the inventors don't have enough money to do anything about their theft. When one does get called out for their illegal, yes illegal, theft they whine about how they are entitled (much the way people that don't want to work whine about how they are entitled to unemployment) and how the mean patent troll is after them. People and companies with entitlement attitudes are ruining this country.
