IN THE UNITED STATES DISTRICT COURT

FOR THE EASTERN DISTRICT OF TEXAS

MARSHALL DIVISION

VALTRUS INNOVATIONS LTD.

vs.

AT&T INC., ET AL.

CIVIL ACTION NO. 2:23-CV-0443-JRG

(Lead Case)

JOINT MOTION TO EXTEND CERTAIN DEADLINES

Plaintiff Valtrus Innovations Ltd and, Defendants T-Mobile USA, Inc. T-Mobile US, Inc., 

Sprint Corp., OnePlus Technology (Shenzhen) Co. Ltd., and OnePlus Mobile Communications 

(Guangdong) Co., Ltd. jointly move to extend certain deadlines shown in the chart below. The 

parties request the following deadlines be extended as follows:

Current Deadline Proposed Deadline Event

December 18, 2023 January 12, 2024 File Proposed Discovery Order

December 26, 2023 January 19, 2024 File Proposed Protective Order

The parties submit that good cause exists for the proposed extension. Among other things, 

the consolidated cases involve three sets of Defendants for which the issues addressed in the 

Discovery Order and Protective Order raise separate issues. For example, Plaintiff asserts nine 

patents against the Verizon and T-Mobile Defendants but only four patents against the OnePlus 

Defendants. The parties continue to discuss how, if at all, the default limits set forth in the 

discovery order should be altered to account for the scope of the case against the Verizon and TMobile Defendants without unduly burdening the OnePlus Defendants, given the relatively 

narrow scope of the case. Additionally, notwithstanding the above, the parties agree that 

discovery may begin on December 26, 2023, as would otherwise be the case if the deadlines were 

not moved. Accordingly, the requested extensions will not affect the remaining schedule.
