Geoffrey.landis writes "According to the Wall Street Journal, there's a new species of patent troll out there. These new trolls sue companies that sell products with an expired patent number on them. That's right, it's against the law to sell a product that's marked with an expired patent number. The potential fine? $500. Per violation. And some of the companies have patent numbers on old plastic molds that have made literally billions of copies. Using whistle-blower laws, 'anyone can file a claim on behalf of the government, and plaintiffs must split any fine award evenly with it.' You've been warned."
