As part of a late July filing spree of Texas monetization firm IP Edge LLC, associated plaintiff Wave Linx LLC sued BigMarker (1:21-cv-01086), Five9 (reportedly soon to be acquired by Zoom) (1:21-cv-01087), GetResponse Services (1:21-cv-01085), Paylocity (6:21-cv-01226), and SpectrumVoIP (2:21-cv-00287). The NPE targets the defendants over the provision of their respective communications platforms (e.g., call center, videoconferencing, and VoIP platforms), targeting features related to providing notifications for incoming calls, live chats, and other messages. The sole patent asserted in this campaign was received from Siemens in October 2018; Wave Linx filed these new cases on the opening days of an evidentiary hearing before the International Trade Commission (ITC) in an investigation triggered by a complaint filed by sister IP Edge plaintiff Q3 Networking LLC, against respondents CommScope, HP Enterprise (HPE) (Aruba Networks), and NETGEAR. There, IP Edge asserts four other patents from among those received in October 2018, arguing the presence of a domestic industry based on the US activities of Siemens.
