The Supreme Court on Monday limited the ability of patent holders to bring infringement lawsuits in courts that have plaintiff friendly reputations, a notable decision that could provide a boost to companies that defend against patent claims. The high court, in an opinion by Justice Clarence Thomas, ruled unanimously that a lower court has been following an incorrect legal standard for almost 30 years that made it possible for patent holders to sue companies in almost any U.S. jurisdiction. From a report: The justices sided 8-0 (PDF) with beverage flavoring company TC Heartland in its legal battle with food and beverage company Kraft Heinz, ruling that patent infringement suits can be filed only in courts located in the jurisdiction where the targeted company is incorporated. Justice Neil Gorsuch did not participate in the decision. The decision overturned a ruling last year by the U.S. Court of Appeals for the Federal Circuit, a Washington-based patent court, that said patent suits are fair game anywhere a defendant company's products are sold.
