Summary
Background
Respondents sought a patent on a method for increasing computer security. A Patent and Trademark Office (PTO) examiner denied the application as obvious, and the PTO's internal review board upheld that denial. The Federal Circuit treated the core question about prior art as one of fact and used a stricter, trial-style "clearly erroneous" standard to overturn the PTO's finding; the Commissioner asked this Court to decide which review rules apply.
Reasoning
The central question was whether courts must use the Administrative Procedure Act's (APA) standards when reviewing PTO factual findings. The Court looked to §706 of the APA and to §559 (which preserves any "additional requirements ... recognized by law") and examined a large sample of pre-APA Patent Office appellate cases. The Court concluded those cases did not clearly show a pre-existing, stricter court-style review requirement, and that Congress intended the APA's uniform agency-review framework to govern. The Court therefore rejected the Federal Circuit's use of the stricter "clearly erroneous" standard and reversed.
Real world impact
As a result, when the Federal Circuit reviews PTO factfinding it must apply APA review standards, giving recognized deference to agency expertise and internal agreement. The decision was not a final ruling on patentability itself; the Court remanded the case for further proceedings consistent with the APA framework. The opinion notes the practical difference between the two review tests is often subtle but may affect some outcomes and strategies for applicants.
Dissents or concurrances
Chief Justice Rehnquist dissented, arguing the Federal Circuit and the patent bar had reasonably concluded a stricter "clearly erroneous" rule existed before the APA and that the Court should have deferred to that specialized court's view.
