The Federal Circuit denied Tesla Inc.'s petition for a writ of mandamus directing the PTO to vacate and reconsider the deputy director’s non-institution decisions relating to Granite Vehicle Ventures LLC’s patents. The court said that the deputy director didn’t exceed his statutory authority in denying IPR review, and that Tesla didn’t show any clear and indisputable right to disturb the non-institution decisions for failure to conduct proper notice-and-comment rulemaking.
