Atlantic IP Services Limited plaintiff Iarnach Technologies Limited has sued a third defendant in its optical networking campaign, hitting Charter Communications (Spectrum Gulf Coast, Spectrum Management) (2:24-cv-00230) over the provision of products necessary for providing DPoE v2.0-compliant networks—including “all hardware and software, optical line terminals (ONTs), and optical network units (ONUs)/optical network terminals (ONTs), transport networks, and DOCSIS back office equipment”. Iarnach previously sued AT&T (AT&T Mobility and several other subsidiaries) in a May 2023 case in which Nokia has successfully intervened and Verizon (Verizon Wireless and several other subsidiaries) in a December 2023 case, all three suits filed in the Eastern District of Texas.
