Wireless Monitoring Systems, LLC has initiated suit for the first time, asserting two patents (8,912,893; 9,280,886) generally related to circuit monitoring. The wireless security systems of defendants 3D Security (2:16-cv-01227), ADT (2:16-cv-01226), CenturyLink (2:16-cv-01228), iSmartAlarm (2:16-cv-01229), and Patroltag (d/b/a Korner d/b/a Korner Safe) (2:16-cv-01230) are accused of infringement. Wireless Monitoring alleges that the “control panels, hubs, and sensors” within those systems constitute devices that monitor an electrical parameter (e.g. the resistance of a circuit), comparing that parameter to values associated with a “safe” or “normal” condition and an “alarm” condition.
