No other deadlines will be affected by this amendment. The Parties do not file this Motion 

for the purposes of delay, but rather so that justice may be done. Good cause supports the Parties’ 

request in view of the scheduling conflicts of the Parties. The Parties and trial counsel for the 

Parties are scheduled for an upcoming jury trial before this Court, which is scheduled to begin on 

August 5, 2024, in Headwater Research LLC v. Samsung Electronics America, Inc. et al., Case 

No. 2:22-cv-00422-JRG-RSP, for which the Parties’ trial preparation, jury trial, and expected posttrial briefing schedules are will conflict with numerous deadlines in this case. The requested 

extension will allow the Parties adequate time to resolve discovery issues that have arisen in the 

ordinary course as well as to complete depositions of their respective witnesses and prepare expert 

disclosures. Accordingly, the Parties believe that good cause supports extending the deadlines in 

this case. Accordingly, the Parties respectfully request that the Court grant this Joint Motion to 

Amend Deadlines.
