Patent trolls are bad, but practicing patent holders are worse. The troll doesn’t want to put you out of business. He just wants a piece of your action. It’s like a tax. It’s those patent holders who actually make a patented item that want to shut down every competing producer. They are by far the bigger drain on the economy.
Huh?? If “patent holders” are making a patented item, it’s THEIRS and unless the “other manufacturers” are licensed, they are thieves.
