Entry of Article 34 Amendments May Be Restricted
Note:
The U.S. Designated/Elected Office may not enter Article 34 amendments if they result in obvious inconsistencies.

Amendments to the international application that were properly made under PCT Article 34 during the international preliminary examination phase (i.e., Chapter II) will be annexed by the International Preliminary Examining Authority to the international preliminary examination report (IPER) and communicated to the elected Offices. See PCT Article 36, PCT Rule 70.16, and MPEP § 1893.03(e). If these annexes are in English, they will normally be entered into the U.S. national stage application by the Office absent a clear instruction by the applicant that the annexes are not to be entered. In this regard, the “Transmittal Letter To The United States Designated/Elected Office (DO/EO/US) Concerning A Submission Under 35 U.S.C. 371” (Form PTO-1390) available at www.uspto.gov/patent/patents-forms includes a check box by which the applicant may expressly instruct the U.S. Designated/Elected Office not to enter the Article 34 amendment(s) in the United States national stage application. However, if entry of the replacement sheets will result in an obvious inconsistency in the description, claims or drawings of the international application, then the annexes will not be entered. If the annexes are in a foreign language, a proper translation of the annexes must be furnished to the Office not later than the expiration of 30 months from the priority date, unless a period has been set pursuant to 37 CFR 1.495(c) to furnish an oath or declaration, English translation of the international application, search fee (37 CFR 1.492(b)), examination fee (37 CFR 1.492(c)), or application size fee (37 CFR 1.492(j)), in which case the translations of the annexes, accompanied by the processing fee set forth in 37 CFR 1.492(f), may be submitted within the period set pursuant to 37 CFR 1.495(c). See 37 CFR 1.495(e). Annexes for which translations are not timely received will be considered canceled. Amendments made under PCT Article 34 to the international application after commencement and entry into the U.S. national phase (see MPEP § 1893.01) will not be considered in a U.S. national stage application. However, applicants may still amend the U.S. national stage application by way of a preliminary amendment submitted in accordance with 37 CFR 1.115 and 37 CFR 1.121.

English Translation Must Match Original Description
Note:
The English translation of annexes must match the original application description to ensure consistency when substituting pages.

Where an English translation of the annexes is provided, the translation must be such that the translation of the originally filed application can be changed by replacing the originally filed application page(s) (of translation) with substitute page(s) of translation of the annex. Thus, applicant should check to be sure that the English translation can be entered by substituting the pages of translation for corresponding pages of the description or claims of the international application without leaving an inconsistency. If entry of the page of translation causes inconsistencies in the description or claims of the international application the translation will not be entered. Non-entry of the annexes will be indicated on the “NOTICE OF ACCEPTANCE OF APPLICATION UNDER 35 U.S.C. 371 AND 37 CFR 1.495” (Form PCT/DO/EO/903). For example, if the translation of the originally filed application has a first page which ends with the first part of paragraph 0012, with the remainder of paragraph 0012 on the next page then the translation of the annex of the first page must include a substitute page or pages ending with the exact same first part of paragraph 0012. This enables the original translated first page of description to be replaced by the translation of the annex without changing the subsequent unamended page(s). Alternatively applicant may submit a preliminary amendment in accordance with 37 CFR 1.121. The fact that an amendment made to the international application during the international phase was entered in the national stage application does not necessarily mean that the amendment is proper. Specifically, amendments are not permitted to introduce “new matter” into the application. See PCT Article 34(2)(b). Where it is determined that such amendments introduce new matter into the application, then the examiner should proceed as in the case of regular U.S. national applications filed under 35 U.S.C. 111(a) by requiring removal of the new matter and making any necessary rejections to the claims. See MPEP §§ 608.04 and 2163.06.

Translation of Foreign Language Annexes Required Within 30 Months
Note:
If annexes are in a foreign language, a proper translation must be submitted to the Office by the 30-month deadline from the priority date.

Amendments to the international application that were properly made under PCT Article 34 during the international preliminary examination phase (i.e., Chapter II) will be annexed by the International Preliminary Examining Authority to the international preliminary examination report (IPER) and communicated to the elected Offices. See PCT Article 36, PCT Rule 70.16, and MPEP § 1893.03(e). If these annexes are in English, they will normally be entered into the U.S. national stage application by the Office absent a clear instruction by the applicant that the annexes are not to be entered. In this regard, the “Transmittal Letter To The United States Designated/Elected Office (DO/EO/US) Concerning A Submission Under 35 U.S.C. 371” (Form PTO-1390) available at www.uspto.gov/patent/patents-forms includes a check box by which the applicant may expressly instruct the U.S. Designated/Elected Office not to enter the Article 34 amendment(s) in the United States national stage application. However, if entry of the replacement sheets will result in an obvious inconsistency in the description, claims or drawings of the international application, then the annexes will not be entered. If the annexes are in a foreign language, a proper translation of the annexes must be furnished to the Office not later than the expiration of 30 months from the priority date, unless a period has been set pursuant to 37 CFR 1.495(c) to furnish an oath or declaration, English translation of the international application, search fee (37 CFR 1.492(b)), examination fee (37 CFR 1.492(c)), or application size fee (37 CFR 1.492(j)), in which case the translations of the annexes, accompanied by the processing fee set forth in 37 CFR 1.492(f), may be submitted within the period set pursuant to 37 CFR 1.495(c). See 37 CFR 1.495(e). Annexes for which translations are not timely received will be considered canceled. Amendments made under PCT Article 34 to the international application after commencement and entry into the U.S. national phase (see MPEP § 1893.01) will not be considered in a U.S. national stage application. However, applicants may still amend the U.S. national stage application by way of a preliminary amendment submitted in accordance with 37 CFR 1.115 and 37 CFR 1.121.

Annex Translation Must Match Original Description
Note:
The translation of the annex must match the original description to ensure consistency when replacing pages during national stage entry.

Where an English translation of the annexes is provided, the translation must be such that the translation of the originally filed application can be changed by replacing the originally filed application page(s) (of translation) with substitute page(s) of translation of the annex. Thus, applicant should check to be sure that the English translation can be entered by substituting the pages of translation for corresponding pages of the description or claims of the international application without leaving an inconsistency. If entry of the page of translation causes inconsistencies in the description or claims of the international application the translation will not be entered. Non-entry of the annexes will be indicated on the “NOTICE OF ACCEPTANCE OF APPLICATION UNDER 35 U.S.C. 371 AND 37 CFR 1.495” (Form PCT/DO/EO/903). For example, if the translation of the originally filed application has a first page which ends with the first part of paragraph 0012, with the remainder of paragraph 0012 on the next page then the translation of the annex of the first page must include a substitute page or pages ending with the exact same first part of paragraph 0012. This enables the original translated first page of description to be replaced by the translation of the annex without changing the subsequent unamended page(s). Alternatively applicant may submit a preliminary amendment in accordance with 37 CFR 1.121. The fact that an amendment made to the international application during the international phase was entered in the national stage application does not necessarily mean that the amendment is proper. Specifically, amendments are not permitted to introduce “new matter” into the application. See PCT Article 34(2)(b). Where it is determined that such amendments introduce new matter into the application, then the examiner should proceed as in the case of regular U.S. national applications filed under 35 U.S.C. 111(a) by requiring removal of the new matter and making any necessary rejections to the claims. See MPEP §§ 608.04 and 2163.06.
