Before: Newman, Clevenger, and DYK. Opinion by DYK. Dissenting opinion by Newman.


Garmin filed in the PTO a petition to institute an inter partes review (IPR) on patented claims owned by Cuozzo. The PTO granted the petition to institute the IPR and concluded that the claims at issue were obvious over prior art. Cuozzo appealed to CAFC, arguing: (1) the petition was defective as failing to identify prior art references for each claim; and (2) a broadest reasonable interpretation (BRI) standard should not be applied in the obviousness determination. CAFC held: (1) the statute prohibits a review on the PTO’s decision to institute the IPR even the final decision was on appeal; and (2) the BRI standard applies in IPR.
