Narrative Opinion Summary
This case involves a declaratory judgment action initiated by Cardiac Pacemakers, Inc. (CPI) against Coratomic, Inc. concerning the validity and potential infringement of three patents related to heart pacemakers. The District Court declared the patents invalid due to obviousness, with the design patent additionally invalidated for being functionally dictated, and ruled no infringement by CPI. The Eighth Circuit affirmed these findings, noting no clear error in the District Court's factual assessments and emphasizing the patents' obviousness to those skilled in the art, thereby sidestepping the infringement issue. Coratomic's challenge to personal jurisdiction was dismissed, as the courts found sufficient business contacts in Minnesota under the state's long-arm statute, compliant with due process. Additionally, the appellate court sustained the lower court's decision to strike Coratomic's jury demand concerning its Microthin pacemakers, citing no new substantive issues in the amended counterclaim. The judgment was affirmed without further elaboration, indicating the straightforward application of established legal principles without broad precedential impact.
