715.01(a)    Reference Is a Joint Patent or Published Application to Applicant and Another [R-07.2015]

[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.]

When subject matter disclosed in a patent or patent application publication filed jointly by S and another is claimed in a later application filed by S, the joint patent or joint patent application publication is a valid reference under pre-AIA 35 U.S.C. 102(a), (e), or (f)  unless overcome by an affidavit or declaration under 37 CFR 1.131(a)  showing prior invention (see MPEP § 715) or by an affidavit or declaration under 37 CFR 1.132. An unequivocal declaration under 37 CFR 1.132  by S that he/she conceived or invented the subject matter that was disclosed but not claimed in the patent or application publication and relied on in the rejection would be sufficient to overcome the rejection. In re DeBaun, 687 F.2d 459, 214 USPQ 933 (CCPA 1982). Where the reference is a U.S. patent or patent application publication which includes a claim reciting the subject matter relied upon in a rejection and that subject matter anticipates or would render obvious the subject matter of a claim in the application under examination, a declaration under 37 CFR 1.132  must also explain the presence of the additional inventor in the reference (e.g., the disclosure in claim 1 of the reference is relied upon to reject the claims; the affidavit or declaration explains that S is the sole inventor of claim 1, and the additional inventor and S are joint inventors of claim 2 of the reference). Disclaimer by the other patentee or applicant of the patent application publication should not be required but, if submitted, may be accepted by the examiner.

Note that an affidavit or declaration under 37 CFR 1.131(a)  cannot be used to overcome a rejection based on a U.S. patent or U.S. patent application publication naming another inventor which claims interfering subject matter as defined in 37 CFR 41.203(a). See MPEP § 715.05. See MPEP § 716.10 for a discussion of the use of 37 CFR 1.132  affidavits or declarations to overcome rejections by establishing that the subject matter relied on in the patent or application publication was the invention of the applicant.

For applications subject to current 35 U.S.C. 102, see MPEP §§ 717 and 2155.01.

Although affidavits or declarations submitted for the purpose of establishing that the reference discloses applicant’s invention are properly filed under 37 CFR 1.132, rather than 37 CFR 1.131(a), such affidavits submitted improperly under 37 CFR 1.131(a)  will be considered as though they were filed under 37 CFR 1.132  to traverse a ground of rejection. In re Facius, 408 F.2d 1396, 161 USPQ 294 (CCPA 1969).
