Last September, Arlington Technologies, LLC, a Dominion Harbor Enterprises, LLC plaintiff, filed its first litigation over a large portfolio of former Avaya patents received earlier in 2024, suing Comcast in a pair of Eastern District of Texas complaints. Those cases have ended, after a notice of settlement. Now, Arlington has filed against Deutsche Telekom (Sprint, T-Mobile) (2:25-cv-00279) in the same district. Targeted is the provision of “wireless access points” that are configured to support 802.11ax and Wi-Fi Multimedia, cellular services that support Voice over LTE (VoLTE), and cellular networks that support STIR/SHAKEN call verification.
