The court filings say that Research In Motion Limited (NASDAQ:RIMM) (TSE:RIM))’s BlackBerry Curve, the iPhone, HTC’s Windows Phone 8X and the Droid X and Razr models all infringe on the patent allegedly owned by Steelhead Licensing. Other devices that Steelhead claims infringe on its patent include Verizon’s JetPack 4G Hotspot and similar devices from other companies on the list.
Currently the patent that’s involved in the lawsuit is listed by the U.S. Patent and Trademark Office as being owned by BT, a network operator in the U.K. However the fillings indicate that BT sold its patents to Steelhead last year.
The company has demanded that a jury be involved in all of these lawsuits and requested damages that will cover past infringement as well as current and future infringement.
