Bartees Cox Jr. contrasts the company image and the public image of the patent troll, Intellectual Ventures (http://www.publicknowledge.org/blog/two-sides-intellectual-ventures). He sums it up, "Intellectual Ventures is giving you the good side of the story. They say that they are champions of invention and they're quick to point out their health and medical research. Everyone else in the battle for patent reform sees the other side. The side that preys on businesses without penalty, that buys up patents to sue innovators building companies, and that ultimately keeps innovation at a standstill while raking in massive profits. Later, he writes, "Because when a company like Intellectual Ventures sits on technologies and patents, waiting for someone to independently make a product to become unintentional fodder for a lawsuit trap, there is no benefit to knowledge, consumers, or to society." Worth a read and thought about the purpose of patents and current experience and whether we wouldn't be better off without them.
