Pursuant to the Parties’ Joint Notice and Stipulation Regarding Case Narrowing (Dkt. 190), 

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

“Samsung”) file this response to notify the Court that Samsung has withdrawn its Eighth 

Affirmative Defense (Inequitable Conduct / Infectious Unenforceability) asserted in Samsung’s 

Amended Answer and Defenses to Plaintiff Headwater Research LLC’s Second Amended 

Complaint for Patent Infringement. Thus, the Court should deny Headwater’s motion for summary 

judgment as moot.
