In June we reported on a boomlet in freelance lawsuits accusing companies of marking their products with outdated patent numbers or with other violations of a federal statute that prohibits the use of false or misleading patent marks on products. On December 28 the Federal Circuit issued a decision that may greatly stimulate the activities of what are already being called “marking trolls”. It holds that courts have discretion to impose the law’s $500 penalty per mislabeled item sold, which means that total penalties might rise to gigantic levels; lawyers who bring the cases then split the proceeds with the federal government in qui tam fashion.
