Affidavit Not Needing Enabling Disclosure
Note:
An affidavit under 37 CFR 1.130 must show the disclosure was made by an inventor or joint inventor, or the subject matter was publicly disclosed before filing.

An affidavit or declaration under 37 CFR 1.130(a) or (b) need not demonstrate that the disclosure by the inventor, a joint inventor, or another who obtained the subject matter disclosed directly or indirectly from an inventor or a joint inventor was an “enabling” disclosure of the subject matter within the meaning of 35 U.S.C. 112(a). Rather, an affidavit or declaration under 37 CFR 1.130 must show that: (1) the disclosure in question was made by the inventor or a joint inventor, or the subject matter disclosed was obtained directly or indirectly from the inventor or a joint inventor (37 CFR 1.130(a)); or (2) the subject matter disclosed had, before such disclosure was made or before such subject matter was effectively filed, been publicly disclosed by the inventor or a joint inventor or another who obtained the subject matter disclosed directly or indirectly from the inventor or a joint inventor (37 CFR 1.130(b)).
