The 11 numbered circuits and the D.C. Circuit are geographically defined by the boundaries of their assigned U.S. district courts. The Tenth Circuit is unique in that it contains a small portion of Idaho and Montana due to the U.S. District Court for the District of Wyoming extending out of state to cover all of Yellowstone National Park. The 13th court of appeals is the Federal Circuit, which has nationwide jurisdiction over certain appeals based on specialized subject matter. All of the courts of appeals also hear appeals from some administrative agency decisions and rulemaking, with by far the largest share of these cases heard by the D.C. Circuit. The Federal Circuit hears appeals from specialized trial courts, primarily the United States Court of International Trade and the United States Court of Federal Claims, as well as appeals from the district courts in patent cases and certain other specialized matters.
