CAFC works through "personal jurisdiction" issues in Trimble; ND Cal holding of "no jurisdiction" reversed

The outcome was a finding of personal jurisdiction:

Trimble Inc. and Innovative Software Engineering, LLC (“ISE”) appeal a judgment dismissing their declaratory judgment noninfringement action against PerDiemCo LLC for lack of personal jurisdiction. PerDiemCo is the owner of eleven patents that it accused Trimble and ISE of infringing in letters and other communications sent to Trimble, a California resident. Relying on this court’s decision in Red Wing Shoe Co. v. Hockerson-Halberstadt, Inc., 148 F.3d 1355 (Fed. Cir. 1998), the United States District Court for the Northern District of California held that it would be unreasonable to assert personal jurisdiction over PerDiemCo based on its communications to Trimble in California. We conclude that Red Wing does not preclude personal jurisdiction on the facts of this case and that the district court had personal jurisdiction over PerDiemCo.

Appeal from the United States District Court for the Northern District of California in No. 4:19-cv-00526-JSW, Judge Jeffrey S. White.
