Cassiopeia IP LLC v. TTE Technology, Inc.

Valyrian IP LLC has become the seventh plaintiff in apparent association with IP Edge LLC to file suit over patents that the monetization firm received from Siemens in October 2018. The patent that Valyrian has now asserted against Avaya (1:19-cv-01436), Grandstream Networks (1:19-cv-01437), ICON Voice Networks (3:19-cv-01829), and Plantronics (Polycom) (1:19-cv-01438) generally relates to a cordless phone system where calls are forwarded from a base station to handsets based on one of three priority levels assigned to a phone number as stored with caller ID info in a directory: “lowest priority” (or “DO NOT DISTURB”), “intermediate priority”, and “highest priority”. The NPE targets the defendants over the provision of cordless phone systems with “Do Not Disturb” features that allow the user to pick certain phone numbers from a directory as “priority” numbers, where calls still go through when Do Not Disturb is enabled.

In March 2019, Cassiopeia IP LLC joined a growing list of other IP Edge affiliates to assert patents received from Siemens in litigation, accusing China Huaxin Post & Telecommunication Economy Development Center (Alcatel-Lucent Enterprise), HP Enterprise (Aruba Networks), and Western Digital of infringement through provision of networking products that maintain a list of discovered network services, including DLNA (Digital Living Network Alliance) and UPnP (Universal Plug and Play) services, that have advertised their availability within a network. The NPE has now added three more cases, this time accusing Best Buy (1:19-cv-00799), TTE Technology (1:19-cv-00800), and Westinghouse Electric (1:19-cv-00801) over the provision of smart TVs that support media casting using the DIAL protocol. Cassiopeia IP is an affiliate of Texas monetization firm IP Edge LLC.

Blueprint IP Solutions LLC and Cassiopeia IP LLC have become the latest affiliates of IP Edge LLC to litigate patents that the Texas monetization firm acquired from Siemens last October. Blueprint IP has sued Fortinet (1:19-cv-00577), Hitachi (Hitachi Vantara) (1:19-cv-00579), HP Enterprise (HPE) (1:19-cv-00578), NetApp (1:19-cv-00580), Oracle (1:19-cv-00581), and Talend (1:19-cv-00582) over a former Siemens patent generally related to a redundant and “geographically separate” pair of “switching systems” where a “monitoring unit” keeps one switching system active and the other in a “hot-standby” mode, and switches the latter into active mode when the former loses network communications. Meanwhile, Cassiopeia IP has filed suit against HPE (Aruba Networks) (1:19-cv-00593), China Huaxin Post & Telecommunication Economy Development Center (Alcatel-Lucent Enterprise) (1:19-cv-00599), and Western Digital (1:19-cv-00594), also in Delaware, but over a former Siemens patent broadly directed to a system that enables the use of network services by detecting all usable services and entering them on a “blackboard”.
