Primary MPEP Section Summaries

This section discusses swearing behind a reference with an affidavit or declaration under 37 C.F.R. 1.131(a). Swearing back, (also called an affidavit or declaration under 37 C.F.R. 1.131) may be used to overcome rejections where the prior art used to establish the rejection was not by “another”, but filed by the same inventor.

This section covers situations where 37 C.F.R. 1.131 affidavits or declarations can and cannot be used and the reference date to be overcome.

For applications subject to pre-AIA 35 U.S.C. 102, when the reference in question is a noncommonly owned U.S. patent or patent application publication claiming the same invention as applicant and its publication date is less than 1 year prior to the presentation of claims to that invention in the application being examined, applicant’s remedy, if any, must be by way of 37 CFR 41.202 instead of 37 CFR 1.131(a).
