715.01 37 CFR 1.131 Affidavits Versus 37 CFR 1.132 Affidavits - 700 Examination of Applications
715.01 37 CFR 1.131 Affidavits Versus 37 CFR 1.132 Affidavits
The purpose of a 37 CFR 1.131 affidavit or declaration is to overcome a prior art rejection by proving invention of the claimed subject matter by applicant prior to the effective date of the reference or activity relied upon in the rejection.
In some situations, an applicant may, alternatively, be able to overcome prior art rejections relying on references or activities which are available as prior art under 35 U.S.C. 102(a) or references which are available as prior art under 35 U.S.C. 102(e) by proving that the subject matter relied upon in the reference or activity was applicant's own invention.
Similarly, where the reference relied upon in a 35 U.S.C. 103 rejection qualifies as prior art only under 35 U.S.C. 102(f) or (g), or, in an application filed on or after November 29, 1999, under 35 U.S.C. 102(e), applicant may be able to overcome this rejection by proving that the subject matter relied upon and the claimed invention were commonly owned or subject to common assignment at the time the later invention was made. See MPEP § 706.02(l)(1) through § 706.02(l)(3).
