Copy of Oath or Declaration for Continuation Applications After September 16, 2012
Note:
A copy of an oath or declaration from a prior application can be submitted with a continuation or divisional application filed on or after September 16, 2012, but must identify the correct application number if filed after the filing date.

A copy of an oath or declaration from a prior application may be submitted with a continuation or divisional application, or with a continuation-in-part application filed on or after September 16, 2012, even if the oath or declaration identifies the application number of the prior application. However, if such a copy of the oath or declaration is filed after the filing date of the continuation or divisional application and an application number has been assigned to the continuation or divisional application (see 37 CFR 1.5(a)), the cover letter accompanying the oath or declaration should identify the application number of the continuation or divisional application. The cover letter should also indicate that the oath or declaration submitted is a copy of the oath or declaration from a prior application to avoid the oath or declaration being incorrectly matched with the prior application file. Furthermore, applicant should also label the copy of the oath or declaration with the application number of the continuation or divisional application in the event that the cover letter is separated from the copy of the oath or declaration.

Oath or Declaration from Prior Application Permitted in Continuation
Note:
A copy of the oath or declaration from a prior nonprovisional application can be used in a continuation or divisional application even if the specification has been revised, as long as the changes do not introduce new matter.

A copy of the oath or declaration from a prior nonprovisional application may be filed in a continuation or divisional application even if the specification for the continuation or divisional application is different from that of the prior application, in that revisions have been made to clarify the text to incorporate amendments made in the prior application, or to make other changes provided the changes do not constitute new matter relative to the prior application. If the examiner determines that the continuation or divisional application contains new matter relative to the prior application, the examiner should so notify the applicant in the next Office action and indicate that the application should be redesignated as a continuation-in-part.
