Mobile Telecommunications Technologies, LLC (MTel) filed suit (2:12-cv-00832) against Sprint Nextel alleging that Sprint’s 4G wireless network infringes a patent related to a two-way communications system between a central network and a mobile device (5,590,403). MTel has filed three prior suits since May 2012, one against Clearwire asserting the ‘403 patent, and two against RIM and UPS asserting a number of additional patents from MTel’s portfolio. The case against Clearwire, of which Sprint has transacted to own a 100 percent share, is currently set for trial in January 2014.
