The Supreme Court's recent decisions in Goodyear and Daimler changed how general personal jurisdiction is understood. They now focus mainly on a defendant's domicile rather than their activities in a state. This shift has led courts to consider using registration statutes as a basis for personal jurisdiction over foreign corporations. The Court's personal jurisdiction analysis has evolved over time, from strict territorial limitations to a more flexible approach based on contacts with a forum. The concept of general jurisdiction has persisted after the landmark International Shoe case, with courts grappling with how to establish jurisdiction over corporations operating across state lines.
