One of the most common problems the Court has faced since the creation of the Federal Circuit has been deciding what standard courts should use to assess the decisions of the Patent and Trademark Office (PTO) when it issues, or refuses to issue, a patent. So, the Court held in 1999 in
Dickinson v. Zurko that Administrative Procedure Act review applies when a rejected applicant seeks direct review in the Federal Circuit. Last Term in
Microsoft v. i4i, the Court reaffirmed long-standing rules that grant a strong presumption of validity when alleged infringers challenge patents in federal district court. On January 9, in
Kappos v. Hyatt, the Court considers yet another such problem – the standard to be applied under Patent Act Section 145, a little-used provision that allows a rejected applicant to file a new action in federal district court challenging the PTO’s denial.
