JOINT MOTION TO CONSOLIDATE 

Plaintiff Headwater Partners II LLC (“Headwater”) and Defendants T-Mobile USA, Inc., 

Case 2:24-cv-00015-JRG-RSP Document 52 Filed 07/01/24 Page 1 of 5 PageID #: 480

Sprint LLC (collectively, “T-Mobile”), AT&T Services, Inc., AT&T Mobility LLC, AT&T Corp. 

(collectively, “AT&T”), Cellco Partnership, d/b/a Verizon Wireless and Verizon Corporate 

Services Group (collectively, “Verizon,” and all together with Headwater, the “Parties”) 

respectfully request that the Court consolidate for pre-trial issues the above-captioned matters 

involving the Parties and pending before the Court for the reasons set forth below: 

1. On January 5, 2024, Headwater filed a lawsuit against Verizon in this district, 

alleging infringement of U.S. Patent Nos. 9,094,868 and 9,413,502 (the “Asserted Patents”). See 

Headwater Partners II LLC v. Cellco Partnership, d/b/a Verizon Wireless, et al., 24-cv-00007 

(E.D. Tex.) (the “Verizon Matter”). 

2. On January 10, 2024, Headwater filed two lawsuits alleging infringement of the 

same Asserted Patents against AT&T and T-Mobile. See Headwater Partners II LLC v. AT&T 

Servs., Inc., et al., 24-cv-00016 (E.D. Tex.) (the “AT&T Matter”); Headwater Partners II LLC 

v. T-Mobile USA, Inc., et al., 24-cv-00015 (E.D. Tex.) (the “T-Mobile Matter”). 

3. On February 13, 2024, the Court consolidated for pre-trial issues the AT&T Matter 

and T-Mobile Matter, and designated the T-Mobile Matter as the lead case (the “AT&T/T-Mobile 

Matter”). See AT&T Matter, Dkt. No. 10; T-Mobile Matter, Dkt. No. 10. The Court did not 

consolidate for pre-trial issues the Verizon Matter with the AT&T/T-Mobile Matter. 

4. The AT&T/T-Mobile Matter and the Verizon Matter share the same schedule 

(outside of trial dates) and discovery orders, and the Parties are represented by the same respective 

outside counsel. 

5. The Parties met and conferred concerning the consolidation for pre-trial issues of 

the AT&T/T-Mobile Matter with the Verizon Matter on June 11, 2024. The Parties respectfully 

submit that consolidating these matters will lead to greater efficiency in case management and

consistent rulings regarding overlapping legal claims, as both matters are pending before this 

Court, both matters contain overlapping questions of law and fact, maintaining separate matters 

would waste the Court’s and Parties’ resources and because there is little to no risk of prejudice 

or confusion resulting from consolidation. 

For the aforementioned reasons, the Parties respectfully request that the Court consolidate 

for pre-trial issues the Verizon Matter into the AT&T/T-Mobile Matter and designate the 

AT&T/T-Mobile Matter as the LEAD CASE following consolidation.
