409.03(c) Legal Representatives of Deceased Inventor Not Available
37 CFR 1.47 should not be considered an alternative to 37 CFR 1.42 or 35 U.S.C. 117 since the language "cannot be found or reached after diligent effort" has no reasonable application to a deceased inventor. In re Application Papers Filed September 10, 1954, 108 USPQ 340 (Comm'r Pat. 1955). See 37 CFR 1.42 and MPEP § 409.01. However, 37 CFR 1.47 does apply where a known legal representative of a deceased inventor cannot be found or reached after diligent effort, or refuses to make application. In such cases, the last known address of the legal representative must be given (see MPEP § 409.03(e)).
