Garmin probably thought getting into the mobile phone game would just be smooth sailing, but it looks like they've made a deadly miscalculation. Okay, that might be over-dramatizing the situation, but the PND-maker is facing a new lawsuit over its upcoming 3G wonder-device, the Nuvifone. Apparently, internet telephone provider Nuvio Corp. feels that Garmin has crossed trademark boundaries just a smidge, alleging the nav company is stepping all over its good name. "Our customers commonly refer to our service as the Nuvio phone," said Jason P. Talley, the company's CEO. Not only is the provider calling for a cease-and-desist on the use of "Nuvifone," but it also wants kickbacks for past infringement, and termination of the word "Nuvi" on any device made by Garmin. Garmin spokesman Ted Gartner says the company has been using the Nuvi name since early 2006 in North America, and earlier in Europe. He went on to add that they don't discuss pending litigation -- though we understand to friends and family he was like, "Pfft, whatever."
