(2) Interlocutory orders appointing receivers, or refusing orders to wind up receiverships or to take steps to accomplish the purposes thereof, such as directing sales or other disposals of property;
(3) Interlocutory decrees of such district courts or the judges thereof determining the rights and liabilities of the parties to admiralty cases in which appeals from final decrees are allowed.
(c) The United States Court of Appeals for the Federal Circuit shall have exclusive jurisdiction —
(2) of an appeal from a judgment in a civil action for patent infringement which would otherwise be appealable to the United States Court of Appeals for the Federal Circuit and is final except for an accounting.
(2) When the chief judge of the United States Court of Federal Claims issues an order under section 798(b) of this title, or when any judge of the United States Court of Federal Claims, in issuing an interlocutory order, includes in the order a statement that a controlling question of law is involved with respect to which there is a substantial ground for difference of opinion and that an immediate appeal from that order may materially advance the ultimate termination of the litigation, the United States Court of Appeals for the Federal Circuit may, in its discretion, permit an appeal to be taken from such order, if application is made to that Court within ten days after the entry of such order.
(3) Neither the application for nor the granting of an appeal under this subsection shall stay proceedings in the Court of International Trade or in the Court of Federal Claims, as the case may be, unless a stay is ordered by a judge of the Court of International Trade or of the Court of Federal Claims or by the United States Court of Appeals for the Federal Circuit or a judge of that court.
(4)
(B) When a motion to transfer an action to the Court of Federal Claims is filed in a district court, no further proceedings shall be taken in the district court until 60 days after the court has ruled upon the motion. If an appeal is taken from the district court’s grant or denial of the motion, proceedings shall be further stayed until the appeal has been decided by the Court of Appeals for the Federal Circuit. The stay of proceedings in the district court shall not bar the granting of preliminary or injunctive relief, where appropriate and where expedition is reasonably necessary. However, during the period in which proceedings are stayed as provided in this subparagraph, no transfer to the Court of Federal Claims pursuant to the motion shall be carried out.
