Provisional Anticipation or Obviousness Based on Common Inventor Application
Note:
A provisional rejection of a second application may be made if it shares at least one inventor with the first application and the first application qualifies as prior art under 35 U.S.C. 102(a)(2).

If a first application has (1) at least one common (joint) inventor or common applicant with a second application or the applications are commonly assigned, and (2) the first application, upon publication or issuance, would qualify as prior art under 35 U.S.C. 102(a)(2) to the second application, then a provisional anticipation or obviousness rejection of the second application may be made on the basis of the first application. Since the first application is not published or issued at the time of the rejection, the rejection must be provisionally made under 35 U.S.C. 102(a)(2) or 103.

Provisional Anticipation or Obviousness Must Be Based on Copending Application
Note:
A provisional rejection for anticipation or obviousness must be based on a copending U.S. patent application that is not yet published or issued.

If a first application has (1) at least one common (joint) inventor or common applicant with a second application or the applications are commonly assigned, and (2) the first application, upon publication or issuance, would qualify as prior art under 35 U.S.C. 102(a)(2) to the second application, then a provisional anticipation or obviousness rejection of the second application may be made on the basis of the first application. Since the first application is not published or issued at the time of the rejection, the rejection must be provisionally made under 35 U.S.C. 102(a)(2) or 103.

Provisional Rejection Can Be Overcome Like Regular Rejection
Note:
A provisional rejection based on prior art can be overcome in the same manner as a regular 35 U.S.C. 102(a)(2) rejection.

A provisional rejection based on 35 U.S.C. 102(a)(2) prior art can be overcome in the same manner that a 35 U.S.C. 102(a)(2) rejection can be overcome. See MPEP § 2152.06. The provisional rejection can also be overcome by abandoning the applications and filing a new application containing the subject matter of both.

Provisional Rejection Overcome by New Application
Note:
A provisional rejection can be overcome by abandoning the current applications and filing a new application that includes both sets of subject matter.

A provisional rejection based on 35 U.S.C. 102(a)(2) prior art can be overcome in the same manner that a 35 U.S.C. 102(a)(2) rejection can be overcome. See MPEP § 2152.06.

Provisional Rejection for Earlier Copending Application
Note:
An examiner must determine if a provisional rejection under 35 U.S.C. 102(a)(2) can be made when an earlier filed, copending, and unpublished U.S. patent application discloses subject matter that would anticipate the claims in a later filed pending U.S. application with a different inventive entity.

If an earlier filed, copending, and unpublished U.S. patent application discloses subject matter which would anticipate the claims in a later filed pending U.S. application which has a different inventive entity, the examiner should determine whether a provisional rejection under 35 U.S.C. 102(a)(2) of the later filed application can be made. In addition, a provisional rejection under 35 U.S.C. 102(a)(2) may be made, in the circumstances described below, if the earlier filed, pending application has been published as redacted (37 CFR 1.217) and the subject matter relied upon in the rejection is not supported in the redacted publication of the patent application.

Confidentiality Requirement for Unpublished Applications
Note:
If no common assignee, applicant, or inventor exists and the application is not published under 35 U.S.C. 122(b), the application must remain confidential and cannot be used as prior art.

If there is no common assignee, common applicant, or common (joint) inventor and the application was not published pursuant to 35 U.S.C. 122(b), the confidential status of applications under 35 U.S.C. 122(a) must be maintained and no rejection can be made relying on the first (earlier filed), unpublished application, or subject matter not supported in a redacted application publication, as prior art under 35 U.S.C. 102(a)(2). For applications subject to pre-AIA 35 U.S.C. 102(g), if the filing dates of the applications are within 6 months of each other (3 months for simple subject matter) then interference may be proper. See MPEP Chapter 2300. If the first application will not be published pursuant to 35 U.S.C. 122(b), it must be allowed to issue once all the statutory requirements are met. After the patent has issued, it may be used as a reference in a rejection under 35 U.S.C. 102(a)(2) in the still pending application as appropriate. See MPEP §§ 2120.01 and 2154.

Issued Patent Can Be Used As Rejection Reference In Still Pending Application
Note:
An issued patent can be referenced in rejecting claims of a still pending application under 35 U.S.C. 102(a)(2) if the conditions are met.

If there is no common assignee, common applicant, or common (joint) inventor and the application was not published pursuant to 35 U.S.C. 122(b), the confidential status of applications under 35 U.S.C. 122(a) must be maintained and no rejection can be made relying on the first (earlier filed), unpublished application, or subject matter not supported in a redacted application publication, as prior art under 35 U.S.C. 102(a)(2).
