Trial Prep Well Underway in Cases Against Earlier Wireless Carrier Defendants, Headwater Research Hits Amazon

Headwater Research LLC’s separate Eastern District of Texas cases against Deutsche Telekom (Sprint, T-Mobile) and Verizon (Verizon Wireless) are set for trial this week. Claims from two patents are to be tried against each defendant set, with Headwater docketing its final selection of seven claims from those two patents as to the Deutsche Telekom defendants; and three claims, as to Verizon. In its runup to trial, the Verizon docket has been hammered by recommended resolutions for the parties’ myriad pretrial motions, as well as (mostly sealed) objections thereto, including recommended denials of Verizon’s motions for summary judgment of noninfringement of the two patents to be tried as well as a recommended grant of a Verizon motion for summary judgment of noninfringement of a third patent. Meanwhile, Headwater Research has also just filed a new complaint, this one in the Western District of Texas, accusing Amazon (7:25-cv-00286) of infringing two other patents from the large family that Headwater has been litigating since October 2022.
