Steelhead Licensing Sues More Mobile Phone Makers and Wireless Services Providers

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.
