Charter and Comcast Sued in Network Handover Campaign
July 13, 2025
In separate Eastern District of Texas complaints, Mobility Workx, LLC has accused Charter Communications (Spectrum Mobile and others) (4:25-cv-00752) and Comcast (Comcast Phone and others) (4:25-cv-00754) of infringing the same two patents asserted across this campaign, begun back in August 2017. Targeted in each complaint is the provision of “a wireless communications network that enables mobility through network handover”. Early in this campaign, the plaintiff disclosed a prominent Texas monetization firm, as “licensing advisor”, as a financially interested nonparty.
The two patents-in-suit (7,697,508; 8,213,417) generally relate to the allocation of network resources. A third patent, broadly pertaining to mobile network emulation, has also been asserted against some campaign defendants, including Amazon, Ericsson, and Samsung. In 2017, Mobility Workx sued Deutsche Telekom (T-Mobile) and Verizon (Verizon Wireless), ramping up its litigation in and after 2023. The prior suits against AT&T (AT&T Mobility), Cisco, Echostar (DISH Wireless) and Samsung, have been dismissed in light of settlements. Litigation against Amazon, Ericsson, and Nokia remains active in the Eastern District of Texas. The accused products include a broad range of mobile devices and wireless networking equipment.
The resource allocation patents comprise a family of two, issuing to the University of Florida Research Foundation, Incorporated (UFRF) in April 2010 and July 2012, respectively. The applications that led to these patents were assigned to UFRF in October 2004 by Abdelsalam (“Sumi”) Helal, a professor, and Edwin Hernandez, his doctoral student. Helal is the director and “principal investigator” of UFRF’s Mobile & Pervasive Computing Laboratory. Hernandez identifies himself as a former Motorola engineer with currently identified positions as the CTO and founder for EGLA Communications, a Florida company that advertises itself as developing a platform that “connects cloud to Cable TV enabling simplified distribution of video and music content”, as well as expert witness services, and as principal of Mobility Workx. Prior to his employment with Motorola, Hernandez also reports having worked for Microsoft.
In connected with the early case against T-Mobile, even though the Eastern District of Texas does not require it, Mobility Workx disclosed three entities with a financial interest in the outcome of the litigation: the plaintiff; Whitaker Chalk Swindle & Schwartz PLLC, as plaintiff’s counsel; and Dominion Harbor Group, LLC, as “licensing advisor” for Mobility Workx. For more detailed coverage of the 2017 cases against T-Mobile and Verizon Wireless, as well as of the formation and control of the plaintiff, see “Mobility Workx Sues Three More” (December 2024). For additional background, including an unsuccessful appeal from that IPR loss that alleged institutional bias, see “Its Tangle with the PTAB Behind It, Mobility Workx Hits AT&T Mobility” (June 2023). More recent reporting on patents moving to another Helal vehicle, see here.
Zeisler PLLC of Miami, Florida filed the new complaints for Mobility Workx. District Judge Amos L. Mazzant has been presiding. 7/11, Eastern District of Texas.
