In that twisty-turny world of patents, it seems that Encyclopedia Britannica is going after TomTom and Magellan for infringement of patents it holds for a “computerized mapping system.” The suit was filed in Wisconsin and also includes a retail store, American TV & Appliance of Madison Inc., with no explanation as to why they were included. A number of news outlets are reporting that TomTom has confirmed the suit, but no specifics seem to be available as yet.
