Aug 21 (Reuters) - Verizon has agreed to settle a

patent infringement lawsuit that led to a $175 million verdict

against the telecom giant last month, according to a filing in

Texas federal court.

Verizon and patent holder Headwater Research filed their notice

of settlement under seal on Tuesday. Spokespeople and attorneys

for the companies did not immediately respond to requests for

comment and more details about the settlement on Thursday.

Headwater obtained the jury verdict in July based on allegations

that Verizon's mobile phones, tablets and cellular networks

infringed its wireless communications patents. Headwater also

won a $279 million verdict against Samsung in a related case in

the same Marshall, Texas, court in April, and settled similar

lawsuits against AT&T ( T ) and T-Mobile earlier this month.

Tyler, Texas-based Headwater was founded by scientist and

inventor Gregory Raleigh. Headwater said in its 2023 complaint

against Verizon that its patented technology allows wireless

devices to "reduce data usage and network congestion, extend

battery life by decreasing power consumption, and enable users

to stay connected."

Headwater said it shared information about its technology

with Verizon under a non-disclosure agreement between 2009 and

2011.

Verizon denied the allegations and argued that the patents

were invalid.

The case is Headwater Research LLC v. Verizon Communications

Inc ( VZ ), U.S. District Court for the Eastern District of Texas, No.

2:23-cv-00352.

For Headwater: Marc Fenster, Reza Mirzaie, Brian Ledahl, Ben

Wang and Adam Hoffman of Russ August & Kabat

For Verizon: Josh Krevitt, Kate Dominguez, Brian Rosenthal,

Robert Vincent and Andrew Robb of Gibson Dunn & Crutcher
