Vringo
Vringo is a technology company. The company won a 2012 intellectual property lawsuit against Google, in which Google was ordered to pay 1.36 percent of US AdWords sales. The ruling was overturned on appeal, in August 2014, in a split 2-1 decision that Vringo is now appealing to the United States Supreme Court. The number of intellectual property suits filed by the firm has led some commentators to refer to the firm as a patent troll.
