ORDER
Defendants T-Mobile USA, Inc. and Sprint Corp. (collectively, “Defendants”) previously filed a Motion for Partial Summary Judgment that Headwater’s Damages are Limited by 35 U.S.C. 287 (the “Motion”). (Dkt. No. 183.) Magistrate Judge Payne entered a Report and Recommendation recommending granting T-Mobile and Sprint’s Motion with respect to Plaintiff Headwater Research LLC (“Plaintiff”) not having given pre-suit actual notice to Defendants, but otherwise recommending denying the Motion. (Dkt. No. 310.) T-Mobile and Sprint have now filed Objections (Dkt. No. 333), with Plaintiff filing a Response (Dkt. No. 343).

Consequently, the Court OVERRULES T-Mobile and Sprint’s Objections, ADOPTS the Report and Recommendation, and ORDERS that the Motion for Partial Summary Judgment that Headwater’s
2.
Damages are Limited by 35 U.S.C. 287 (Dkt. No. 183) is GRANTED as to Plaintiff not having given pre-suit actual notice to Defendants, but is otherwise DENIED.
So ORDERED and SIGNED this 24th day of July, 2025.
