Case: Patents/Procedure (Fed. Cir.)

The Federal Circuit denied Inari Agriculture Inc.'s petition seeking mandamus review of the decision of the Patent Trial and Appeal Board denying post-grant review of Pioneer Hi-Bred International Inc.'s plant patent. According to the court, Inari’s petition raises only constitutional challenges that it did not directly raise before the Patent Office, and the court declined to exercise its discretion to reach an issue raised for the first time here, particularly given the significant inexcusable delay in filing this petition.
