Just when you thought the lawsuits were over, it looks like Apple, RIM, Motorola and a bunch of other companies including US telcos have been hit with a massive lawsuit, and surprise, surprise, it looks like they are being sued over alleged patent infringement with regards to a wireless patent owned by Steelhead Licensing. The patent in question is a process in which how a handover is determined in a mobile radio network, including plurality of cells where each cell is associated with a base station that is supporting communication with a mobile device, or at least that’s what Steelhead Licensing claims in its filing of the lawsuit.


Steelhead Licensing has named Apple, RIM, Motorola, HTC, LG, Kyocera, NEC Casio, Pantech, Sony, ZTE, and US carriers such as AT&T, Verizon, T-Mobile, Sprint and MetroPCS. Apparently the carriers are just as “guilty” because of devices such as Verizon’s JetPack 4G Hotspot, and the SonicMobile 4G Hotspot from T-Mobile, along with AT&T’s Mobile Hotspot Elevate 4G. According to the USPTO, the patent it seems has been listed as belonging to UK network operator BT, but Steelhead claims that they bought the patent from them last year and are now seeking damages for past, present and possibly future infringements.
