TechSys Insights, LLC filed TechSys Insights, LLC v. Verizon Communications, Inc., No. 2:26-cv-00798 (E.D. Tex. Marshall), on September 8, 2026, before Judge Rodney Gilstrap. The complaint names Verizon Communications and nine Verizon operating companies, including Cellco Partnership d/b/a Verizon Wireless and several Verizon Business and network entities.

Patents and asserted claims

The complaint asserts U.S. Patents 8,989,591 (at least claim 11); 9,014,558 (at least claim 13); and 9,020,350 (at least claim 1). TechSys alleges Verizon has known about the technology since about 2013 and seeks damages for willful infringement.

U.S. Patent 8,989,591 (Remote optical demarcation point) covers putting an optical demarcation point inside customer-controlled equipment so the service provider can still control whether an optical signal enters the provider network. Asserted claims: at least claim 11. Claim 11 covers an optical-demarcation system with a customer interface inside the customer's network element in an optical network linking customer and provider elements.

U.S. Patent 9,014,558 (Client grooming interface) covers provider-side optical demarcation that gates access based on optical-signal characteristics and mapping or multiplexing of information flows. Asserted claims: at least claim 13. Claim 13 covers an optical-demarcation system with a provider interface inside the provider's network element.

U.S. Patent 9,020,350 (Optical spectrum recovery) covers rearranging optical spectrum so unused slices become contiguous by expanding a channel reservation, shifting the channel, and then collapsing the reservation without tearing the channel down. Asserted claims: at least claim 1. Claim 1 covers a method of changing an optical channel's frequency range or polarization state from an initial allocation to a target allocation by expanding, shifting, and collapsing the reservation without changing the signal's spectral width.

What is accused

TechSys points the claims at Verizon's fiber-optic network and related systems and services, including broadband and fiber access, SD-WAN / enterprise networking, data-center and DCI uses, and cellular/5G backhaul that ride Verizon fiber. The complaint discusses Verizon fiber facilities and equipment vendors such as Nokia, Ciena, Fujitsu, and Ericsson as part of that network story.

What it means

This is an East Texas carrier suit about how a national fiber network demarcates, grooms, and repacks optical spectrum - aimed at Verizon's fiber footprint rather than a single consumer gadget.

What to watch next

Watch for service, Verizon's answer or early motions, and claim-construction positions on demarcation and spectrum-recovery terms.
