IN THE UNITED STATES DISTRICT COURT

FOR THE EASTERN DISTRICT OF TEXAS

MARSHALL DIVISION

COBBLESTONE WIRELESS, LLC,

Plaintiff,

v. 

SAMSUNG ELECTRONICS CO., LTD., 

SAMSUNG ELECTRONICS AMERICA, INC.,

Defendants.

Case No. 2:23-cv-00285-JRG-RSP

JURY TRIAL DEMANDED

UNOPPOSED MOTION TO AMEND DOCKET CONTROL ORDER

Defendants Samsung Electronics Co., Ltd. and Samsung Electronics America, Inc.

(collectively “Samsung”) move to amend the Docket Control Order (“DCO”) as set forth below 

and in the attached proposed order. The proposal would extend by three business days the deadline 

to comply to serve invalidity contentions pursuant to Patent Local Rule 3-3 and to produce 

documents accompanying invalidity contentions pursuant to Patent Local Rule 3-4. The proposal 

does not alter any other deadline. 

A scheduling order may be modified “upon a showing of good cause and by leave of the 

district judge.” Fed. R. Civ. P. 16(b). “[W]hen determining whether good cause exists to allow a 

deviation from the court’s scheduling order,” this circuit considers four factors: “(1) the 

explanation for the failure to [meet the deadline]; (2) the importance of the [modification of the 

deadline]; (3) potential prejudice in allowing the [modification]; and (4) the availability of a 

continuance to cure such prejudice.” Travelpass Group, LLC v. Caesars Entm’t Corp., No. 

5:18CV153-RWS-CMC, 2020 WL 10963947, at *4 (E.D. Tex. Nov. 9, 2020) (brackets in 

original). Each factor supports Samsung’s motion to amend the DCO.

The modest extension will accommodate for the holiday season, as well as allow time for 

Samsung to finalize its preliminary invalidity contentions and collect the documents it is required 

to produce accompanying the invalidity contentions. Samsung’s modest request—a threebusiness-day extension carrying over the weekend—would accommodate these circumstances. 

Samsung believes the parties would not suffer prejudice in allowing the modification of the DCO

because it would not result in an extension of the overall schedule, and the extension is modest. 

Moreover, this extension is unopposed. There is no need for continuance to cure prejudice to either 

party as this extension does not modify any other deadlines. 

Accordingly, Samsung respectfully requests the Court to issue the attached Amended 

DCO. The proposed dates are set forth below:
