TechSys Insights, LLC filed a patent infringement complaint on September 8, 2026, in the Eastern District of Texas, No. 2:26-cv-00798, before Judge Rodney Gilstrap. The docket names Verizon Communications, Inc. and multiple Verizon operating companies, including Cellco Partnership d/b/a Verizon Wireless and several Verizon Business and network entities.
What patents are reported
Contemporary press coverage of the filing identifies U.S. Patents 8,989,591 ("Remote optical demarcation point"), 9,014,558 ("Client grooming interface"), and 9,020,350 ("Optical spectrum recovery"). Public patent records confirm those titles. The free complaint text was not confirmed for this write-up, so claim charts and product mapping details are limited to what the coverage reports.
What is accused
According to that coverage, TechSys accuses Verizon's fiber optic network, SD-WAN architecture and services, broadband access services, data centers, AI-related network services, and wireless and cellular services. TechSys also alleges Verizon has known about the technology since 2013.
What it means in plain terms
This is an East Texas networking suit aimed at a large carrier's fiber and SD-WAN footprint, including AI-related network services. Until the complaint exhibits are confirmed, treat the product list as plaintiff-side theory from secondary coverage, not as a court finding.
What to watch next
Watch for service, Verizon's answer or early motions, and confirmation of the asserted claims and accused product charts from the complaint exhibits. Also watch whether TechSys files parallel suits against other carriers on the same three patents.
