Pre-AIA 35 U.S.C. 103(c) Applies Only to Obviousness Rejection
Note:
The rule states that Pre-AIA 35 U.S.C. 103(c) applies only to prior art used in an obviousness rejection under 35 U.S.C. 103(a).

Pre-AIA 35 U.S.C. 103(c) applies only to prior art usable in an obviousness rejection under 35 U.S.C. 103(a). Subject matter that qualifies as anticipatory prior art under pre-AIA 35 U.S.C. 102 is not affected, and may still be used to reject claims as being anticipated. In addition, double patenting rejections, based on subject matter now disqualified as prior art in amended pre-AIA 35 U.S.C. 103(c), should still be made as appropriate. See 37 CFR 1.78(c) and MPEP § 804.

Patent Grants After December 10, 2004 Exempt From CREATE Act
Note:
This rule states that patents granted on or after December 10, 2004, are exempt from the requirements of the CREATE Act unless they fall under current 35 U.S.C. 102 and 103.

The CREATE Act (Public Law 108-453, 118 Stat. 3596 (2004)) was enacted on December 10, 2004, and is effective for applications for which the patent is granted on or after December 10, 2004, except those patents subject to the current 35 U.S.C. 102 and 35 U.S.C. 103. Specifically, the CREATE Act amended pre-AIA 35 U.S.C. 103(c) to provide that:

Amendment to Pre-AIA 35 U.S.C. 103(c) Now Applies to Pending Applications
Note:
The change in pre-AIA 35 U.S.C. 103(c) from 'subsection (f) or (g)' to 'one or more of subsections (e), (f), or (g)' now applies to applications filed before November 29, 1999, that were pending on December 10, 2004.

The effective date provision of the CREATE Act provided that its amendments shall apply to any patent (including any reissue patent) granted on or after December 10, 2004, except those patents subject to the current 35 U.S.C. 102 and 103. The CREATE Act also provided that its amendment shall not affect any final decision of a court or the Office rendered before December 10, 2004, and shall not affect the right of any party in any action pending before the Office or a court on December 10, 2004, to have that party’s rights determined on the basis of the provisions of title 35, United States Code, in effect on December 9, 2004. Since the CREATE Act also includes the amendment to pre-AIA 35 U.S.C. 103(c) made by section 4807 of the AIPA (see Public Law 106-113, 113 Stat. 1501, 1501A-591 (1999)), the change of “subsection (f) or (g)” to “one or more of subsections (e), (f), or (g)” in pre-AIA 35 U.S.C. 103(c) is now also applicable to applications filed prior to November 29, 1999, that were pending on December 10, 2004.

Pre-AIA 103(c) Applies Only to Certain Prior Art
Note:
The rule states that pre-AIA 35 U.S.C. 103(c), as amended by the CREATE Act, can only be used to disqualify prior art that qualifies under pre-AIA 35 U.S.C. 102(e), (f), or (g) and is relied upon in a rejection under pre-AIA 35 U.S.C. 103(a).

Pre-AIA 35 U.S.C. 103(c), as amended by the CREATE Act, continues to apply only to subject matter which qualifies as prior art under pre-AIA 35 U.S.C. 102(e), (f), or (g), and which is being relied upon in a rejection under pre-AIA 35 U.S.C. 103(a). If the rejection is anticipation under pre-AIA 35 U.S.C. 102(e), (f), or (g), pre-AIA 35 U.S.C. 103(c) cannot be relied upon to disqualify the subject matter in order to overcome or prevent the anticipation rejection. Likewise, pre-AIA 35 U.S.C. 103(c) cannot be relied upon to overcome or prevent a double patenting rejection. See 37 CFR 1.78(c) and MPEP § 804.

Recapture Doctrine Limits Reissued Claims
Note:
The recapture doctrine restricts the presentation of amended or cancelled claims in reissue applications for patents granted after December 10, 2004, due to potential disqualification under the CREATE Act.

Because the CREATE Act applies only to patents granted on or after December 10, 2004, the recapture doctrine may prevent the presentation of claims in the reissue applications that had been amended or cancelled (e.g., to avoid a rejection under pre-AIA 35 U.S.C. 103(a) based on subject matter that may now be disqualified under the CREATE Act) during the prosecution of the application which resulted in the patent being reissued.

Same Owner Prior Art Disqualified Against Invention
Note:
If subject matter and the claimed invention were owned by the same person at the time of invention, such prior art cannot be used against the claimed invention.

Enacted on November 29, 1999, the American Inventors Protection Act (AIPA) added subject matter which was prior art under former 35 U.S.C. 103(a) via pre-AIA 35 U.S.C. 102(e) as disqualified prior art against the claimed invention if that subject matter and the claimed invention “were, at the time the invention was made, owned by the same person or subject to an obligation of assignment to the same person.” The 1999 change to pre-AIA 35 U.S.C. 103(c) applied to all utility, design and plant patent applications filed on or after November 29, 1999. The Cooperative Research and Technology Enhancement Act of 2004 (CREATE Act), in part, redesignated the former 35 U.S.C. 103(c) to pre-AIA 35 U.S.C. 103(c)(1) and made this provision effective to all applications in which the patent is granted on or after December 10, 2004, but the AIA provides that certain applications are subject to the current 35 U.S.C. 102 and 103, see MPEP § 2159. Therefore, the provision of pre-AIA 35 U.S.C.103(c)(1) is effective for all applications (utility, design, plant and reissue) pending on or after December 10, 2004, including applications filed prior to November 29, 1999, except those applications subject to the current 35 U.S.C. 102 and 103. The amendment to pre-AIA 35 U.S.C. 103(c)(1) does not affect any application filed before November 29, 1999 and issued as a patent prior to December 10, 2004. See MPEP § 2159.

Common Ownership at Time of Invention Required for Prior Art Disqualification
Note:
The rule requires that there must be a statement showing common ownership between the reference and the application at the time the invention was made to disqualify prior art under pre-AIA 35 U.S.C. 103(c).

The burden of establishing that subject matter is disqualified as prior art is placed on applicant once the examiner has established a prima facie case of obviousness based on the subject matter. For example, the fact that the reference and the application have the same assignee is not, by itself, sufficient to disqualify the prior art under pre-AIA 35 U.S.C. 103(c). There must be a statement that the common ownership was “at the time the invention was made.”

Claims Amended to Overcome Pre-AIA Rejection Cannot Be Presented in Reissue
Note:
Claims amended or cancelled to overcome a pre-AIA rejection based on prior art cannot be presented in a reissue application if the prior art could not be disqualified under pre-AIA 35 U.S.C. 103(c).

For reissue applications, the doctrine of recapture may prevent the presentation of claims in the reissue applications that were amended or cancelled from the application which matured into the patent for which reissue is being sought, if the claims were amended or cancelled to overcome a rejection under 35 U.S.C. 103(a) based on prior art under pre-AIA 35 U.S.C. 102(e) which was not able to be disqualified under pre-AIA 35 U.S.C. 103(c) in the application that issued as a patent. If an examiner determines that this situation applies in the reissue application under examination, a consultation with the Office of Patent Legal Administration should be initiated via the Technology Center Quality Assurance Specialist.

Amendment to Pre-AIA 103(c)(1) Does Not Affect Patents Issued Before December 2004
Note:
The amendment to pre-AIA 103(c)(1), which disqualified certain prior art, does not affect patents issued before December 10, 2004.

Enacted on November 29, 1999, the American Inventors Protection Act (AIPA) added subject matter which was prior art under former 35 U.S.C. 103(a) via pre-AIA 35 U.S.C. 102(e) as disqualified prior art against the claimed invention if that subject matter and the claimed invention “were, at the time the invention was made, owned by the same person or subject to an obligation of assignment to the same person.” The 1999 change to pre-AIA 35 U.S.C. 103(c) applied to all utility, design and plant patent applications filed on or after November 29, 1999. The Cooperative Research and Technology Enhancement Act of 2004 (CREATE Act), in part, redesignated the former 35 U.S.C. 103(c) to pre-AIA 35 U.S.C. 103(c)(1) and made this provision effective to all applications in which the patent is granted on or after December 10, 2004, but the AIA provides that certain applications are subject to the current 35 U.S.C. 102 and 103, see MPEP § 2159. Therefore, the provision of pre-AIA 35 U.S.C.103(c)(1) is effective for all applications (utility, design, plant and reissue) pending on or after December 10, 2004, including applications filed prior to November 29, 1999, except those applications subject to the current 35 U.S.C. 102 and 103. The amendment to pre-AIA 35 U.S.C. 103(c)(1) does not affect any application filed before November 29, 1999 and issued as a patent prior to December 10, 2004. See MPEP § 2159.

Reexamination Proceeding Conditions for Pre-AIA 35 U.S.C. 103(c)
Note:
Determines whether pre-AIA 35 U.S.C. 103(c) applies in reexamination proceedings based on the patent's grant date and applicable changes.

In a reexamination proceeding, however, one must look at whether or not the patent being reexamined was granted on or after December 10, 2004, and whether the patent is subject the current 35 U.S.C. 102 to determine whether pre-AIA 35 U.S.C. 103(c), as amended by the CREATE Act, applies. For a reexamination proceeding of a patent granted prior to December 10, 2004, on an application filed on or after November 29, 1999, it is the 1999 changes to pre-AIA 35 U.S.C. 103(c) that are applicable to the disqualifying commonly assigned/owned prior art provisions of pre-AIA 35 U.S.C. 103(c). For a reexamination proceeding of a patent granted prior to December 10, 2004, on an application filed prior to November 29, 1999, neither the 1999 nor the 2004 changes to pre-AIA 35 U.S.C. 103(c) are applicable. Therefore, only prior art under pre-AIA 35 U.S.C. 102(f) or (g) used in a rejection under pre-AIA 35 U.S.C. 103(a) may be disqualified under the commonly assigned/owned prior art provisions of 35 U.S.C. 103(c).

Pre-AIA 103(c) Disqualification for Patents Granted Before December 2004
Note:
Only prior art under pre-AIA 102(f) or (g) can be disqualified in reexamination proceedings for patents granted before December 10, 2004.

In a reexamination proceeding, however, one must look at whether or not the patent being reexamined was granted on or after December 10, 2004, and whether the patent is subject the current 35 U.S.C. 102 to determine whether pre-AIA 35 U.S.C. 103(c), as amended by the CREATE Act, applies. For a reexamination proceeding of a patent granted prior to December 10, 2004, on an application filed on or after November 29, 1999, it is the 1999 changes to pre-AIA 35 U.S.C. 103(c) that are applicable to the disqualifying commonly assigned/owned prior art provisions of pre-AIA 35 U.S.C. 103(c). For a reexamination proceeding of a patent granted prior to December 10, 2004, on an application filed prior to November 29, 1999, neither the 1999 nor the 2004 changes to pre-AIA 35 U.S.C. 103(c) are applicable.

Consultation with Office of Patent Legal Administration Required for Certain Reissue Applications
Note:
An examiner must consult the Office of Patent Legal Administration via the Technology Center Quality Assurance Specialist if a reissue application amends or cancels claims to overcome a pre-AIA 103 rejection based on prior art that could not be disqualified under pre-AIA 103(c).

For reissue applications, the doctrine of recapture may prevent the presentation of claims in the reissue applications that were amended or cancelled from the application which matured into the patent for which reissue is being sought, if the claims were amended or cancelled to overcome a rejection under 35 U.S.C. 103(a) based on prior art under pre-AIA 35 U.S.C. 102(e) which was not able to be disqualified under pre-AIA 35 U.S.C. 103(c) in the application that issued as a patent. If an examiner determines that this situation applies in the reissue application under examination, a consultation with the Office of Patent Legal Administration should be initiated via the Technology Center Quality Assurance Specialist.

Anticipatory Prior Art Not Affected by Pre-AIA 103(c)
Note:
Subject matter qualifying as anticipatory prior art under pre-AIA 102 can still be used to reject claims as anticipated, despite the disqualification of certain prior art under 103(c).

Pre-AIA 35 U.S.C. 103(c) applies only to prior art usable in an obviousness rejection under 35 U.S.C. 103(a). Subject matter that qualifies as anticipatory prior art under pre-AIA 35 U.S.C. 102 is not affected, and may still be used to reject claims as being anticipated. In addition, double patenting rejections, based on subject matter now disqualified as prior art in amended pre-AIA 35 U.S.C. 103(c), should still be made as appropriate. See 37 CFR 1.78(c) and MPEP § 804.

Applicant Must Prove Prior Art Disqualification After Examiner's Prima Facie Case
Note:
The applicant must provide evidence to disqualify subject matter as prior art after the examiner establishes a prima facie case of obviousness.

The burden of establishing that subject matter is disqualified as prior art is placed on applicant once the examiner has established a prima facie case of obviousness based on the subject matter. For example, the fact that the reference and the application have the same assignee is not, by itself, sufficient to disqualify the prior art under pre-AIA 35 U.S.C. 103(c). There must be a statement that the common ownership was “at the time the invention was made.”

Amendments Apply to Patents Filed After December 10, 2004
Note:
The CREATE Act amendments apply to patents granted on or after December 10, 2004, except those subject to current 35 U.S.C. 102 and 103.

The effective date provision of the CREATE Act provided that its amendments shall apply to any patent (including any reissue patent) granted on or after December 10, 2004, except those patents subject to the current 35 U.S.C. 102 and 103. The CREATE Act also provided that its amendment shall not affect any final decision of a court or the Office rendered before December 10, 2004, and shall not affect the right of any party in any action pending before the Office or a court on December 10, 2004, to have that party’s rights determined on the basis of the provisions of title 35, United States Code, in effect on December 9, 2004. Since the CREATE Act also includes the amendment to pre-AIA 35 U.S.C. 103(c) made by section 4807 of the AIPA (see Public Law 106-113, 113 Stat. 1501, 1501A-591 (1999)), the change of “subsection (f) or (g)” to “one or more of subsections (e), (f), or (g)” in pre-AIA 35 U.S.C. 103(c) is now also applicable to applications filed prior to November 29, 1999, that were pending on December 10, 2004.
