As part of its late August filing burst, patent monetization firm IP Edge LLC, through plaintiff Valyrian IP LLC, added cases against first Dialpad (1:21-cv-01221) and then Infratel (2:21-cv-01172) to a litigation campaign begun in July 2019. A single former Siemens patent, generally related to a cordless phone system where calls are forwarded from a base station to handsets based on priority, has been at issue throughout. Valyrian IP targets call forwarding and/or call acceptance and rejection features, in these latest complaints, within the Dialpad and MightyCall communications platforms, respectively.
