It's hard to think of any business more inherently obnoxious than a patent troll. These are the tech-world parasites that buy up troves of intellectual property, not so that they can make a product, but so that they can turn around and sue successful creators & small businesses for patent infringement with the aim of nabbing a quick and profitable settlement. They've infested the courts over the last decade, and by one count are now responsible for more than half of all U.S. patent cases, potentially costing American businesses some $29 billion a year. Oregon congressman Peter DeFazio introduced a bill aimed at putting the trolls out of commission. His smart and simple legislation, called the SHIELD Act, would force trolls that lose in court to reimburse the companies.
