Whether administrative patent judges are principal or inferior officers under the Appointments Clause

QUESTIONS PRESENTED 1. Whether, for purposes of the Appointments Clause, U.S. Const. Art. IL § 2, Cl. 2, administrative patent judges of the U.S. Patent and Trademark Office are principal officers who must be appointed by the President with the Senate’s advice and consent, or “inferior Officers” whose appointment Congress has permissibly vested in a department head. 2. Whether, if administrative patent judges are principal officers, the court of appeals properly cured any Appointments Clause defect in the current statutory scheme prospectively by severing the application of 5 U.S.C. § 7513(a) to those judges.
