Newbury Park-based Nomadix, a developer of network gateway hardware, is in a major patent infringement offensive. Nomadix said late Wednesday evening that it has filed a patent infringement lawsuit against Hewlett-Packard Company, Wayport, Inc., iBAHN Corporation, Guest-Tek Interactive Entertainment Ltd., Guest-Tek Interactive Entertainment, Inc., LodgeNet Interactive Corporation, LodgeNet StayOnline, Inc., On Command Corporation, Aruba Networks, Inc., Superclick, Inc. and Superclick Networks, Inc., over what it says is unauthorized use of its patents.

The company said that eight of its more than 100 patents are involved in the litigation. Nomadix is owned by DOCOMO interTouch Pte. Ltd, which acquired the firm in 2008. Nomadix is being represented by Knobbe Martens Olson in the lawsuit.
