Late last month, Valyrian IP LLC added another round of complaints to its calling features campaign, suing 8x8 (1:22-cv-00562) and Charter Communications (1:22-cv-00563) in the District of Delaware and TPx Communications (6:22-cv-00431) in the Western District of Texas. The IP Edge LLC plaintiff has been litigating a single former Siemens patent since July 2019, again targeting call forwarding and/or call acceptance and rejection features within defendant systems, here, the 8x8 Business Phone, Spectrum Enterprise Unified Communications, and TPx Cloud Communication platforms, respectively.
