    • (i) A copy of the decision granting a petition to accord § 1.47 status to the prior application, unless all inventors or legal representatives have filed an oath or declaration to join in an application accorded status under § 1.47 of which the continuation or divisional application claims a benefit under 35 U.S.C. 120 , 121 , or 365(c) ; and
    • (ii) If one or more inventor(s) or legal representative(s) who refused to join in the prior application or could not be found or reached has subsequently joined in the prior application or another application of which the continuation or divisional application claims a benefit under 35 U.S.C. 120 , 121 , or 365(c) , a copy of the subsequently executed oath(s) or declaration(s) filed by the inventor or legal representative to join in the application.
