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.

Last May, Atlantic IP Services Limited plaintiff Iarnach Technologies Limited sued AT&T (AT&T Mobility and several other subsidiaries) in the Eastern District of Texas over optical networking patents received from ZTE earlier in 2023. Nokia successfully intervened in September, the case moving into discovery. Now, Iarnach has filed a second suit, also in East Texas, this one against Verizon (Verizon Wireless and several other subsidiaries) (2:23-cv-00631), over the same five patents, infringement allegations again focused on the provision of “all components necessary”—including “hardware and software, optical line terminals (ONTs), and optical network units (ONUs)/optical network terminals (ONTs)”—for providing its fiber-optic networks and network services.

Iarnach Technologies Limited, a plaintiff tied to Dublin-based monetization firm Atlantic IP Services, has filed its first litigation, suing AT&T (AT&T Mobility and several other subsidiaries) (2:23-cv-00231) in an Eastern District of Texas complaint. Five optical networking patents are asserted, with infringement allegations focused on the provision of “all components necessary”—including “hardware and software, optical line terminals (ONTs), and optical network units (ONUs)/optical network terminals (ONTs)”—in providing its fiber-optic networks and network services. Iarnach received the patents from ZTE earlier this year.

Patent assignments executed in late 2022 and early 2023 continue to surface among USPTO data, with several transactions hinting at possible litigation campaigns to come. The assignees include a newly surfaced Atlantic IP Services Limited NPE, multiple NPEs apparently associated with a familiar figure in patent monetization, and an NPE that—according to public records—has received funding from a prominent litigation finance firm.
