Reference Is a Patent or Published Application Naming Different Inventive Entity With at Least One Common Inventor
Note:
A patent or application publication naming an inventive entity including joint inventor S and another joint inventor can be used as prior art against a later application naming sole inventor S until proven otherwise.

When subject matter disclosed in a patent or patent application publication (reference) naming an inventive entity including joint inventor S and another joint inventor is claimed in a later application naming sole inventor S without the joint inventor, the reference may be properly applied under pre-AIA 35 U.S.C. 102(a), (e), or (f) until 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 traversing the rejection. An unequivocal declaration under 37 CFR 1.132 by S that S conceived or invented the subject matter that was disclosed but not claimed in the patent or application publication and relied on in the rejection has been sufficient to overcome the rejection. In re DeBaun, 687 F.2d 459, 214 USPQ 933 (CCPA 1982))(declaration corroborated by attached drawing). However, an affidavit or declaration under 37 CFR 1.132 that is only a naked assertion of inventorship by an (joint) inventor who has an interest at stake and that fails to provide any context, explanation or evidence to support that assertion is insufficient to show that the relied-upon subject matter was the work of the inventive entity. See EmeraChem Holdings, LLC v. Volkswagen Grp. of Am., Inc., 859 F.3d 1341, 1345, 123 USPQ2d 1146, 1149 (Fed. Cir. 2017) (The court found the declaration submitted by joint inventor Campbell more than twenty years after the invention insufficient to establish that he and Mr. Guth (deceased) alone invented the subject matter disclosed in a patent naming Campbell, Guth, Danziger, and Padron as joint inventors because "[n]othing in the declaration itself, or in addition to the declaration, provides any context, explanation, or evidence to lend credence to [Campbell’s] bare assertion."). 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 joint 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 joint inventor and S are joint inventors of claim 2 of the reference). Testimony or disclaimer from the other joint inventor(s) named in the reference is usually not required but, if submitted, should be considered by the examiner.

Inventorship Declaration to Overcome Rejection
Note:
An unequivocal declaration by an inventor that they conceived the subject matter disclosed but not claimed in a patent or application publication is sufficient to overcome a rejection, provided it is corroborated. However, a naked assertion without context or evidence is insufficient.

When subject matter disclosed in a patent or patent application publication (reference) naming an inventive entity including joint inventor S and another joint inventor is claimed in a later application naming sole inventor S without the joint inventor, the reference may be properly applied under pre-AIA 35 U.S.C. 102(a), (e), or (f) until 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 traversing the rejection. An unequivocal declaration under 37 CFR 1.132 by S that S conceived or invented the subject matter that was disclosed but not claimed in the patent or application publication and relied on in the rejection has been sufficient to overcome the rejection. In re DeBaun, 687 F.2d 459, 214 USPQ 933 (CCPA 1982))(declaration corroborated by attached drawing). However, an affidavit or declaration under 37 CFR 1.132 that is only a naked assertion of inventorship by an (joint) inventor who has an interest at stake and that fails to provide any context, explanation or evidence to support that assertion is insufficient to show that the relied-upon subject matter was the work of the inventive entity. See EmeraChem Holdings, LLC v. Volkswagen Grp. of Am., Inc., 859 F.3d 1341, 1345, 123 USPQ2d 1146, 1149 (Fed. Cir. 2017) (The court found the declaration submitted by joint inventor Campbell more than twenty years after the invention insufficient to establish that he and Mr. Guth (deceased) alone invented the subject matter disclosed in a patent naming Campbell, Guth, Danziger, and Padron as joint inventors because "[n]othing in the declaration itself, or in addition to the declaration, provides any context, explanation, or evidence to lend credence to [Campbell’s] bare assertion."). 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 joint 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 joint inventor and S are joint inventors of claim 2 of the reference). Testimony or disclaimer from the other joint inventor(s) named in the reference is usually not required but, if submitted, should be considered by the examiner.

Insufficient Declaration for Inventorship
Note:
A declaration alone by a joint inventor is insufficient to establish sole invention without providing context, explanation, or evidence.

When subject matter disclosed in a patent or patent application publication (reference) naming an inventive entity including joint inventor S and another joint inventor is claimed in a later application naming sole inventor S without the joint inventor, the reference may be properly applied under pre-AIA 35 U.S.C. 102(a), (e), or (f) until 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 traversing the rejection. An unequivocal declaration under 37 CFR 1.132 by S that S conceived or invented the subject matter that was disclosed but not claimed in the patent or application publication and relied on in the rejection has been sufficient to overcome the rejection. In re DeBaun, 687 F.2d 459, 214 USPQ 933 (CCPA 1982))(declaration corroborated by attached drawing). However, an affidavit or declaration under 37 CFR 1.132 that is only a naked assertion of inventorship by an (joint) inventor who has an interest at stake and that fails to provide any context, explanation or evidence to support that assertion is insufficient to show that the relied-upon subject matter was the work of the inventive entity.

Declaration Required to Overcome Invention Claim Rejection
Note:
A declaration must be submitted by an inventor to overcome a rejection based on subject matter disclosed in a patent or application publication without being claimed, ensuring it includes context and evidence supporting the inventorship claim.

When subject matter disclosed in a patent or patent application publication (reference) naming an inventive entity including joint inventor S and another joint inventor is claimed in a later application naming sole inventor S without the joint inventor, the reference may be properly applied under pre-AIA 35 U.S.C. 102(a), (e), or (f) until 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 traversing the rejection. An unequivocal declaration under 37 CFR 1.132 by S that S conceived or invented the subject matter that was disclosed but not claimed in the patent or application publication and relied on in the rejection has been sufficient to overcome the rejection. In re DeBaun, 687 F.2d 459, 214 USPQ 933 (CCPA 1982))(declaration corroborated by attached drawing). However, an affidavit or declaration under 37 CFR 1.132 that is only a naked assertion of inventorship by an (joint) inventor who has an interest at stake and that fails to provide any context, explanation or evidence to support that assertion is insufficient to show that the relied-upon subject matter was the work of the inventive entity. See EmeraChem Holdings, LLC v. Volkswagen Grp. of Am., Inc., 859 F.3d 1341, 1345, 123 USPQ2d 1146, 1149 (Fed.

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 joint 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 joint inventor and S are joint inventors of claim 2 of the reference). Testimony or disclaimer from the other joint inventor(s) named in the reference is usually not required but, if submitted, should be considered by the examiner.

Declaration Under 37 CFR 1.132 Must Explain Additional Joint Inventor
Note:
A declaration under 37 CFR 1.132 must explain the presence of an additional joint inventor in a reference where the subject matter relied upon anticipates or renders obvious claims in the application.

When subject matter disclosed in a patent or patent application publication (reference) naming an inventive entity including joint inventor S and another joint inventor is claimed in a later application naming sole inventor S without the joint inventor, the reference may be properly applied under pre-AIA 35 U.S.C. 102(a), (e), or (f) until 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 traversing the rejection.

Examiner Should Consider Joint Inventor's Statement
Note:
The examiner should consider any statement from a joint inventor named in the reference if submitted, but it is not usually required.

When subject matter disclosed in a patent or patent application publication (reference) naming an inventive entity including joint inventor S and another joint inventor is claimed in a later application naming sole inventor S without the joint inventor, the reference may be properly applied under pre-AIA 35 U.S.C. 102(a), (e), or (f) until 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 traversing the rejection.
