409.03(a) At Least One Joint Inventor Available [R-11.2013]
[Editor Note: This MPEP section is not applicable to applications filed on or after September 16, 2012.]
Pre-AIA 37 CFR 1.47(a) and pre-AIA 35 U.S.C. 116, second paragraph, requires all available joint inventors to file an application "on behalf of" themselves and on behalf of a joint inventor who "cannot be found or reached after diligent effort" or who refuses to "join in an application."
In addition to other requirements of law (pre-AIA 35 U.S.C. 111(a) and 115 ), an application deposited in the U.S. Patent and Trademark Office pursuant to pre-AIA 37 CFR 1.47(a) must meet the following requirements:
- (A) All the available joint inventors must (1) make oath or declaration on their own behalf as required by pre-AIA 37 CFR 1.63 or 1.175 (see MPEP §§ 602, 605.01, 602.09, and 1414) and (2) make oath or declaration on behalf of the nonsigning joint inventor as required by pre-AIA 37 CFR 1.64. An oath or declaration signed by all the available joint inventors with the signature block of the nonsigning inventor(s) left blank may be treated as having been signed by all the available joint inventors on behalf of the nonsigning inventor(s), unless otherwise indicated.
- (B) The application must be accompanied by proof that the nonsigning inventor (1) cannot be found or reached after diligent effort or (2) refuses to execute the application papers. See MPEP § 409.03(d).
- (C) The last known address of the nonsigning joint inventor must be stated. See MPEP § 409.03(e).
