HEADWATER RESEARCH LLC,

Plaintiff,

v.

T-MOBILE USA, INC. AND SPRINT CORP.,

Defendants.

Civil Action No. 2:23-CV-00379-JRG-RSP

HEADWATER RESEARCH LLC,

Plaintiff,

v.

T-MOBILE USA, INC. AND SPRINT CORP.,

Defendants.

Civil Action No. 2:23-CV-00377-JRG-RSP

JOINT MOTION TO AMEND DOCKET CONTROL ORDER AND ALIGN

CLAIM CONSTRUCTION PROCEEDINGS WITH VERIZON -352 CASE

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

Sprint LLC (“T-Mobile”) jointly file this Joint Motion to Amend Docket Control Order and Align 

Claim Construction Proceedings with Verizon -352 Case as follows: 

Under the operative Docket Control Order (Dkt. 42), the current dates for claim 

construction briefing and the claim construction hearing are: 

• September 20, 2024 – Comply with P.R. 4-5(a) (Opening Claim Construction Brief) and 

Submit Technical Tutorials (if any)

• October 4, 2024 – Comply with P.R. 4-5(b) (Responsive Claim Construction Brief)

• October 11, 2024 – *Comply with P.R. 4-5(c) (Reply Claim Construction Brief)

Case 2:23-cv-00379-JRG-RSP Document 84 Filed 09/17/24 Page 1 of 5 PageID #: 4913

• October 18, 2024 – *Comply with P.R. 4-5(d) (Joint Claim Construction Chart)

• November 1, 2024 – *Claim Construction Hearing – 9:00 a.m. in Marshall, Texas before 

Judge Roy Payne.

The parties jointly request a brief extension of each of the above deadlines to align them 

with the claim construction deadlines in Headwater Research LLC v. Cellco Partnership d/b/a 

Verizon Wireless et al., 2-23-cv-00352-JRG-RSP (E.D. Tex.) (“Verizon -352 Case”). In that case, 

Headwater asserts the same patents and claims. Furthermore, in this case and the Verizon -352 

Case, the parties (Plaintiff Headwater on one side and Defendants T-Mobile and Verizon on the 

other side) have identified the same terms for construction and proposed the same constructions 

for each term. Therefore, all parties believe it is appropriate to consolidate claim construction 

briefing and conduct one claim construction hearing for this case and the Verizon -352 Case. The 

adjustments requested herein are not for purposes of delay but instead to preserve the Court and 

parties’ resources and avoid duplicative briefing and argument on identical issues. 

Accordingly, the parties respectfully request that the Court grant this motion and extend 

the deadlines for the parties to comply with P.R. 4-5(a)–(d) and the claim construction hearing as 

follows: 

• October 8, 2024 – Comply with P.R. 4-5(a) (Opening Claim Construction Brief) and 

Submit Technical Tutorials (if any)

• October 22, 2024 – Comply with P.R. 4-5(b) (Responsive Claim Construction Brief)

• October 29, 2024 – *Comply with P.R. 4-5(c) (Reply Claim Construction Brief)

• November 5, 2024 – *Comply with P.R. 4-5(d) (Joint Claim Construction Chart)

• November 19, 2024 – *Claim Construction Hearing – 9:00 a.m. in Marshall, Texas before 

Judge Roy Payne.
