This morning, the Federal Circuit released a nonprecedential opinion addressing a patent infringement case appealed from a district court. Here is the introduction to the opinion.
Caddo Systems, Inc. v. Siemens Aktiengesellschaft (AG) (Nonprecedential)
This is a patent-infringement action by Caddo Systems, Inc. and 511 Technologies, Inc. (collectively, Caddo) against Siemens Aktiengesellschaft (AG) and Siemens Industry, Inc. The district court entered summary judgment for Siemens Industry based on an agreement between Caddo and Microsoft settling earlier litigation. Caddo Systems, Inc. v. Siemens Aktiengesellschaft (AG), No. 20 C 05927, 2022 WL 444134 (N.D. Ill. Feb. 11, 2022) (Caddo I). The district court then dismissed Caddo’s complaint against Siemens AG for lack of personal jurisdiction. Caddo Systems, Inc. v. Siemens Aktiengesellschaft (AG), No. 20 C 05927, 2022 WL 704779 (N.D. Ill. Mar. 9, 2022) (Caddo II). Caddo timely appeals both rulings. We have jurisdiction under 28 U.S.C. § 1295(a)(1). We affirm both rulings.
