Another Texas NPE managed by patent attorney Stephen McArthur has launched a litigation campaign. Soverain IP LLC has accused Microsoft (2:17-cv-00204) of infringing six patents (5,708,780; 6,212,634; 6,279,112; 7,191,447; 8,606,900; 8,935,706) and Apple (2:17-cv-00207) of infringing four of them (the ‘780, ‘634, ‘447, and ‘706 patents). The patents generally relate to various aspects of network communications, and the NPE identifies a wide list of accused products for each defendant. Soverain IP’s voluminous complaints detail the development of the patents-in-suit, which belong to a portfolio with members that have been previously litigated in the Eastern District of Texas.

Texas NPE Forward Thinking Tracking LLC has kicked off its first litigation campaign with a series of lawsuits filed over the last week targeting the real time location systems and asset tracking products of multiple defendants. The new complaints hit AeroScout (with alleged partners and distributors Extronics, Exloc Instruments, IoEworx, Stanley Black & Decker, and Vizzia Technologies) (2:16-cv-01172), AiRISTA Flow (with the alleged former owner of the accused system, Ekahau) (2:16-cv-01141), CenTrak (with Vizzia) (2:16-cv-01125), Elpas (with Sensormatic Electronics d/b/a Tyco Security Products) (2:16-cv-01143), RF Code (2:16-cv-01168), Savi Technology (2:16-cv-01169), TeleTracking Technologies (2:16-cv-01173), Vestac (2:16-cv-01174), and Zebra Technologies (ZIH) (2:16-cv-01175). Each complaint asserts a single patent (6,989,741) generally related to object tracking.
