Requirement for Referencing Prior Application
Note:
An application must reference a prior filed application to claim its filing date if it is filed before the patenting, abandonment, or termination of proceedings on the first application.

An application for patent for an invention disclosed in the manner provided by section 112(a) (other than the requirement to disclose the best mode) in an application previously filed in the United States, or as provided by section 363 or 385 which names an inventor or joint inventor in the previously filed application shall have the same effect, as to such invention, as though filed on the date of the prior application, if filed before the patenting or abandonment of or termination of proceedings on the first application or on an application similarly entitled to the benefit of the filing date of the first application and if it contains or is amended to contain a specific reference to the earlier filed application. No application shall be entitled to the benefit of an earlier filed application under this section unless an amendment containing the specific reference to the earlier filed application is submitted at such time during the pendency of the application as required by the Director. The Director may consider the failure to submit such an amendment within that time period as a waiver of any benefit under this section. The Director may establish procedures, including the requirement for payment of the fee specified in section 41(a)(7), to accept an unintentionally delayed submission of an amendment under this section.

Continuation-In-Part Not Entitled to Parent Filing Date Without Proper Disclosure
Note:
A continuation-in-part application claiming both benefit under 35 U.S.C. 120 and priority under 35 U.S.C. 119(a)-(d) must meet the conditions of 35 U.S.C. 120; otherwise, it is not entitled to the parent application’s filing date.

Where a continuation-in-part application claims benefit under 35 U.S.C. 120 of the filing date of an earlier application, and also claims priority under 35 U.S.C. 119(a) – (d) of a foreign application through the earlier application, and the conditions of 35 U.S.C. 120 are not met, e.g., insufficient disclosure under 35 U.S.C. 112, the continuation-in-part application is not entitled to the benefit of the filing date of the parent application. In this situation, a determination must be made as to whether the foreign application would qualify as prior art under pre-AIA 35 U.S.C. 102(d) / 172. To qualify as prior art under pre-AIA 35 U.S.C. 102(d) / 172, the foreign application (for patent or registration) must have been filed more than six months before the filing date of the U.S. (CIP) application and the foreign application for patent/registration must have matured into a form of patent protection prior to the filing date of the U.S. (CIP) application. To determine the status of the foreign application, the charts in MPEP § 1504.02 should be used. If the foreign application for patent/registration has matured into a form of patent protection, the foreign application would qualify as prior art under pre-AIA 35 U.S.C. 102(d) / 172 and the examiner should consider whether the design shown in the foreign application papers would anticipate or render the claim in the CIP application obvious. If the design shown in the foreign application papers would anticipate or render the claim in the CIP application obvious, the claim should be rejected under 35 U.S.C. 102 / 103 using form paragraphs 15.74.01 and 15.75.fti followed with a rejection under pre-AIA 35 U.S.C. 102(d) / pre-AIA 35 U.S.C. 103(a).

Note:
The Director may establish procedures, including a surcharge, to accept an unintentionally delayed submission of an amendment that references an earlier filed application.

An application for patent for an invention disclosed in the manner provided by the first paragraph of section 112 of this title in an application previously filed in the United States, or as provided by section 363 of this title, which is filed by an inventor or inventors named in the previously filed application shall have the same effect, as to such invention, as though filed on the date of the prior application, if filed before the patenting or abandonment of or termination of proceedings on the first application or on an application similarly entitled to the benefit of the filing date of the first application and if it contains or is amended to contain a specific reference to the earlier filed application. No application shall be entitled to the benefit of an earlier filed application under this section unless an amendment containing the specific reference to the earlier filed application is submitted at such time during the pendency of the application as required by the Director. The Director may consider the failure to submit such an amendment within that time period as a waiver of any benefit under this section. The Director may establish procedures, including the payment of a surcharge, to accept an unintentionally delayed submission of an amendment under this section.

Timely Submission of Reference Required During Pendency
Note:
Failure to timely submit the reference required under 35 U.S.C. 120 and 37 CFR 1.78 in a design application during its pendency waives any benefit under 35 U.S.C. 120, 121, 365(c), or 386(c).

Except as provided for in 37 CFR 1.78(e), the failure to timely submit the reference required under 35 U.S.C. 120 and 37 CFR 1.78 in a design application during its pendency is considered a waiver of any benefit under 35 U.S.C. 120, 121, 365(c) or 386(c). See 37 CFR 1.78(d)(3)(iii).

Examiner Form Paragraphs

Examiner form paragraphs are standard language that you might see in an Office Action or communication from the USPTO. Examiners have latitude to change the form paragraphs, but you will often see this exact language.

¶ 15.26 ¶ 15.26 Identification of Prior Application(s) in Nonprovisional Applications – Benefit Claimed
¶ 15.74 ¶ 15.74 Continuation-In-Part

Reference to this design application as a continuation-in-part under 35 U.S.C. 120 is acknowledged. Unless the filing date of the earlier application is actually needed, such as to avoid intervening prior art, the entitlement to priority in this CIP application will not be considered. See In re Corba , 212 USPQ 825 (Comm’r Pat. 1981).

Examiner Note

This form paragraph should be used to notify applicant that the C-I-P application is not entitled to the benefit of the parent application under 35 U.S.C. 120 .
