[Editor Note: This MPEP section is not applicable to applications subject to the first inventor to file provisions of the AIA unless being relied upon to overcome a rejection under pre-AIA 35 U.S.C. 102(g). See 35 U.S.C. 100 (note) and MPEP § 2159. For a discussion of 37 CFR 1.130, affidavits or declarations of attribution or prior public disclosure in applications subject to the first inventor to file provisions of the AIA, see MPEP § 717. For a discussion of affidavits or declarations under 37 CFR 1.131(c), see MPEP § 718.]
Unless it is a statutory bar, a rejection under pre-AIA 35 U.S.C. 102 or 103 based on an activity showing that the claimed invention was used or known prior to the filing date of the application may be overcome by an affidavit or declaration under 37 CFR 1.131(a) establishing a date of invention prior to the date of the activity. Alternatively, the applicant(s) may overcome the rejection by filing a specific affidavit or declaration under 37 CFR 1.132 showing that the activity was performed by the inventor or at least one joint inventor.
