As recently predicted by RPX, Delaware plaintiff Castlemorton Wireless, LLC has launched litigation, suing Avaya (1:20-cv-00059), Cox (1:20-cv-00060), Datto (1:20-cv-00058), and Onkyo (Pioneer Electronics) (1:20-cv-00057) in the state of its formation, as well as Arista Networks (6:20-cv-00023), Bose (6:20-cv-00029), Charter Communications (6:20-cv-00024), Comcast (6:20-cv-00034), Deutsche Telekom (T-Mobile) (6:20-cv-00027), Juniper Networks (6:20-cv-00026), Nokia (6:20-cv-00037), SoftBank (Sprint) (6:20-cv-00036), and Verizon (6:20-cv-00035) in the Western District of Texas and Consolidated Communications (5:20-cv-00005) and F-Secure (5:20-cv-00007) in the Eastern District of Texas. A single patent, generally related to the use of radio-frequency (RF) measurement equipment to detect the carrier frequency of a symmetrical, direct-sequence, spread-spectrum (DSSS) signal, is asserted. The NPE’s infringement allegations target a wide range of Wi-Fi-enabled products (including network management systems; access points, routers, gateways, and wireless modules; IP phones and videophones; and AV receivers) that support the detection of a carrier frequency in a DSSS signal through their implementation of the 802.11b and g standards.
