"The Study relates to a graphical interface providing a touch screen keyboard display that may not be minimized, maximized, closed or deleted. In a 2008 complaint filed in federal court in Chicago, SP Technologies, LLC (SPT) accused Garmin Limited and Garmin International, Inc. of infringing SPT’s patent. Garmin is a market leader in the portable navigation devices market. SPT is the owner of U.S. Patent No. 6,784,873 B1. In its complaint, SPT accused Garmin of infringing the patent by the sale of Garmin’s touch screen personal navigation devices “(such as the nuvi 260).” Garmin’s nuvi product line is part of Garmin’s auto/mobile segment. […] This litigation follows prior industry action from SPT involving this patent including infringement actions that have settled against Apple’s iPhone and iPod Touch (settled May, 2008) and Magellan Navigation products (settled January, 2009), in addition to ongoing cases against Samsung Group, HTC Corporation and TomTom."
