ORDER
Defendants AT&T Corp., AT&T Mobility LLC, AT&T Mobility II LLC, and AT&T Services Inc., and intervenors Ericsson Inc. and Nokia of America Corp. previously filed a Motion for Leave to Add Preclusion to Answers (Dkt. No. 476), as well as the related Motion for Summary Judgment on Issue Preclusion (Dkt. No. 477). Magistrate Judge Payne entered a Report and Recommendation (Dkt. No. 507), recommending grant of Defendants/Intervenor’s Motion for Leave to Add Preclusion to Answers, and grant-in-part of Defendants/Intervenor’s Motion for Summary Judgment on Issue Preclusion as to the Nokia base stations. Defendants/ Intervenors have now filed Objections (Dkt. No. 526).
After conducting a de novo review of the Motion for Leave to Add Preclusion to Answers, and the Motion for Summary Judgment on Issue Preclusion; the Report and Recommendation; and the briefing on Defendants/Intervenor’s Objections, the Court
2agrees with the reasoning provided within the Report and Recommendation and concludes . that the Objections fail to show that the Report and Recommendation was erroneous. Consequently, the Court OVERRULES Defendants/Intervenor’s Objections and ADOPTS the Report and Recommendation. The Court ORDERS that the Motion for Leave to Add Preclusion to Answers (Dkt. No. 476) is GRANTED, and that the Motion for Summary Judgment on Issue Preclusion (Dkt. No. 477) is GRANTED-IN-PART such that issue preclusion applies to argument of infringement by Nokia base stations.
So ORDERED and SIGNED this 3rd day of September, 2025.
