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). If the reference is claiming the same invention as the application and its publication date is less than 1 year prior to the presentation of claims to that invention in the application, this fact should be noted in the Office action. The reference can then be overcome only by way of interference. See MPEP Chapter 2300.

The expression “prior to one year from the date on which the patent was granted” in pre-AIA 35 U.S.C. 135(b) includes the one-year anniversary date of the issuance of a patent. See Switzer v.

A 37 CFR 1.131(a) affidavit is ineffective to overcome a United States patent or patent application publication, not only where there is a verbatim correspondence between claims of the application and of the patent, but also where there is no patentable distinction between the respective claims. In re Clark, 457 F.2d 1004, 173 USPQ 359 (CCPA 1972); In re Hidy, 303 F.2d 954, 133 USPQ 650 (CCPA 1962); In re Teague, 254 F.2d 145, 117 USPQ 284 (CCPA 1958); In re Ward, 236 F.2d 428, 111 USPQ 101 (CCPA 1956); In re Wagenhorst, 62 F.2d 831, 16 USPQ 126 (CCPA 1933).

If the application (or patent under reexamination) and the U.S. patent or patent application publication contain claims which are identical, or which are not patentably distinct, then the application and patent are claiming "interfering subject matter" as defined in 37 CFR 41.203(a).

As provided in 37 CFR 41.203(a), an interference exists if the subject matter of a claim of one party would, if prior art, have anticipated or rendered obvious the subject matter of a claim of the opposing party and vice versa. An applicant who is claiming an invention which is identical to, or obvious in view of, the invention as claimed in a domestic patent or patent application publication cannot employ an affidavit under 37 CFR 1.131(a) as a means for avoiding an interference with the reference. To allow an applicant to do so would result in the issuance of two patents to the same invention.

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).

If the reference is a U.S. patent which claims the same invention as the application and its issue date is more than 1 year prior to the presentation of claims to that invention in the application, a rejection of the claims of the application under pre-AIA 35 U.S.C. 135(b)(1) applicable generally to applications subject to pre-AIA 35 U.S.C. 102, see MPEP § 2159, should be made. See In re McGrew, 120 F.3d 1236, 1238, 43 USPQ2d 1632, 1635 (Fed.

The expression “prior to one year from the date on which the patent was granted” in pre-AIA 35 U.S.C. 135(b) includes the one-year anniversary date of the issuance of a patent. See Switzer v.

Form paragraph 23.14 or 23.14.01 may be used when making a rejection under pre-AIA 35 U.S.C. 135(b).

As provided in 37 CFR 41.203(a), an interference exists if the subject matter of a claim of one party would, if prior art, have anticipated or rendered obvious the subject matter of a claim of the opposing party and vice versa. An applicant who is claiming an invention which is identical to, or obvious in view of, the invention as claimed in a domestic patent or patent application publication cannot employ an affidavit under 37 CFR 1.131(a) as a means for avoiding an interference with the reference. To allow an applicant to do so would result in the issuance of two patents to the same invention.

Since 37 CFR 1.131(a) defines "interfering subject matter" in the same way as the interference rules (37 CFR 41.203(a)), the USPTO cannot prevent an applicant from overcoming a reference by a 37 CFR 1.131(a) affidavit or declaration on the grounds that the reference claims applicant’s invention and, at the same time, deny applicant an interference on the grounds that the claims of the application and those of the reference are not for substantially the same invention. See In re Eickmeyer, 602 F.2d 974, 202 USPQ 655 (CCPA 1979). Where, in denying an applicant’s motion in interference to substitute a broader count, it is held that the limitation to be deleted was material for the opponent patentee, this constitutes a holding that the proposed count is for an invention which is not interfering subject matter with respect to the claims of the reference. Therefore, the applicant may file an affidavit or declaration under 37 CFR 1.131(a) to overcome a prior art rejection based on the reference. Adler v. Kluver, 159 USPQ 511 (Bd. Pat. Int. 1968).

Where the reference and the application or patent under reexamination are commonly owned, and the inventions defined by the claims in the application or patent under reexamination and by the claims in the reference are not identical but are not patentably distinct, a terminal disclaimer and an affidavit or declaration under 37 CFR 1.131(c) may be used to overcome a rejection under pre‑AIA 35 U.S.C. 103(a).
