A party to a proceeding under this part may file one request for Director Review of a decision as provided in paragraph (a) of this section, instead of filing a request for rehearing of that decision pursuant to § 42.71(d) , subject to the limitations herein and any further guidance provided by the Director.

A decision on institution, a final decision, a decision granting rehearing of such decision on institution or final decision, or any other decision concluding a proceeding brought under 35 U.S.C. 135 , 311 , or 321 shall become the final agency decision unless:(1) A party requests rehearing or Director Review within the time provided by § 42.71(d) or an extension of time for a request for Director Review is granted pursuant to paragraph (c)(1) of this section; or(2) The Director initiates sua sponte review as provided by § 42.75(b). Upon denial of a request for Director Review of a final decision, of a decision granting rehearing of a final decision, or of any other decision concluding a proceeding brought under 35 U.S.C. 135 , 311 , or 321 , the Board's decision becomes the final agency decision.(e)Process - (1)Effect on underlying proceeding. Unless the Director orders otherwise, and except as provided in paragraph (e)(3) of this section, a request for Director Review or the initiation of review on the Director's own initiative does not stay the time for the parties to take action in the underlying proceeding.(2)Grant and scope. If the Director grants Director Review, the Director shall issue an order or decision that will be made part of the public record, subject to the limitations of any protective order entered in the proceeding or any other applicable requirements for confidentiality. If the Director grants review and does not subsequently withdraw the grant, the Director Review will conclude with the issuance of a decision or order that provides the reasons for the Director's disposition of the case.(3)Appeal. A party may appeal a Director Review decision of a final decision under 35 U.S.C. 135 , 318 , or 328 , a decision granting rehearing of a final decision under 35 U.S.C. 135 , 318 , or 328 , or any other appealable decision concluding a proceeding brought under 35 U.S.C. 135 , 311 , or 321 to the United States Court of Appeals for the Federal Circuit using the same procedures for appealing other decisions under 35 U.S.C. 141(c) , 141(d) , 319 . Director Review decisions on decisions on institution are not appealable. A request for Director Review of a final decision, a decision granting rehearing of a final decision, or any other appealable decision concluding a proceeding brought under 35 U.S.C. 135 , 311 , or 321 , or the initiation of a review on the Director's own initiative of such a decision, will be treated as a request for rehearing under § 90.3(b)(1) of this chapter and will reset the time for appeal until after all issues on Director Review in the proceeding are resolved.(f)Delegation. The Director may delegate their review of a decision provided in paragraph (a) of this section, subject to any conditions provided by the Director.(g)Ex parte communications.
