Steelhead Licensing filed six separate suits against Acer, Amazon, Asustek, Dell, America Movil (and its subsidiaries PRTC and TELPRI), and Infosonics alleging that the defendants’ tablets and mobile phones infringe a patent related to a process for determining the manner in which a handover from one cell to another is performed in a mobile environment (5,678,185). Last week, Steelhead Licensing asserted the same patent in 15 suits against other handset makers and wireless network operators, including Apple, AT&T, Deusche Telekom, HTC, Kyocera, LG Electronics, MetroPCS, Motorola Mobility, NEC Casio Mobile, Pantech, RIM, Sony, Sprint Nextel, Verizon, and ZTE.  The patent-in-suit originated with British Telecommunications and was assigned to Steelhead Licensing by FTE Exchange in December 2012.  RPX reviewed the patent-in-suit as an open market opportunity (BT Wireless – OMA) in June 2012.  1/11, District of Delaware, 1:2013-cv-00076; 1:2013-cv-00077; 1:2013-cv-00078; 1:2013-cv-00079; 1/14, District of Puerto Rico, 3:2013-cv-01030; 3:2013-cv-01031.
