JURY TRIAL DEMANDED

JOINT MOTION TO AMEND DOCKET CONTROL ORDER

Plaintiff Headwater Research LLC (“Headwater”) and Defendants Samsung Electronics 

Co., Ltd. and Samsung Electronics America, Inc. (collectively, “Defendants” or “Samsung”), 

(collectively, the “Parties”) respectfully file this Joint Motion to Amend the Docket Control Order 

and would show the Court as follows:

The current deadline for the Parties to complete fact discovery is September 10, 2024. The 

Parties request a brief extension of this deadline to accommodate additional depositions that were 

not able to be scheduled until at or after the current close of fact discovery. The Parties similarly 

request brief extensions to the current deadlines for opening expert reports, rebuttal expert reports, 

and the close of expert discovery to enable the Parties to prepare fulsome expert reports that 

address discovery provided at or after the current close of fact discovery. Neither the deadline for 

dispositive/Daubert motions, nor any other deadlines will be affected by these amendments. 

The Parties represent that this Motion is not filed for the purposes of delay but rather so 

that justice may be served. The Parties have met and conferred and are jointly seeking the relief 

sought in this Motion.
