Aug 13 (Reuters) - AT&T ( T ) and patent owner Headwater

Research told a Texas federal court on Tuesday that they have

settled Headwater's lawsuit accusing the telecom giant of

violating its rights in wireless communications technology.

The companies asked the court to pause the case in light of

the settlement before a trial that was set to begin on Thursday,

according to an entry on the court's docket. Spokespeople for

AT&T ( T ) and attorneys for Headwater did not immediately respond to

requests for comment and more information.

Wireless carrier T-Mobile also settled a Headwater

lawsuit over related technology on Tuesday, according to a

separate court filing. Attorneys and spokespeople for T-Mobile

did not immediately respond to a request for comment on

Wednesday.

Tyler, Texas-based Headwater was founded by scientist and

inventor Gregory Raleigh. His company won a $279 million jury

verdict against Samsung and a $175 million verdict against

Verizon in separate cases over wireless technology in the same

Marshall, Texas, court earlier this year.

Headwater sued AT&T ( T ) and T-Mobile in 2023, alleging their

products infringed patents related to reducing data usage and

network congestion. The lawsuits said that both companies copied

Headwater's inventions after Raleigh met with their employees.

AT&T ( T ) and T-Mobile both denied the allegations and argued that

the patents were invalid.

The cases are Headwater Research LLC v. AT&T Inc ( T ), U.S.

District Court for the Eastern District of Texas, No.

2:23-cv-00397 and Headwater Research LLC v. T-Mobile US Inc ( TMUS ),

U.S. District Court for the Eastern District of Texas, No.

2:23-cv-00379.

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

Wang and Paul Kroeger of Russ August & Kabat

For AT&T ( T ): Nick Mathews, Kevin Hess and James Quigley of

McKool Smith

For T-Mobile: Josh Krevitt, Katherine Dominguez, Brian

Rosenthal, Robert Vincent and Andrew Robb of Gibson Dunn &

Crutcher
