If the applicant is notified in a notice of allowability that an oath or declaration in compliance with § 1.63, or substitute statement in compliance with § 1.64, executed by or with respect to each named inventor has not been filed, the applicant must file each required oath or declaration in compliance with § 1.63, or substitute statement in compliance with § 1.64, no later than the date on which the issue fee is paid to avoid abandonment. This time period is not extendable under § 1.136 (see § 1.136(c)).

(3) Each inventor did not make a contribution to the subject matter of every claim of the application.

(c) If multiple inventors are named in a nonprovisional application, each named inventor must have made a contribution, individually or jointly, to the subject matter of at least one claim of the application and the application will be considered to be a joint application under 35 U.S.C. 116.
