Published English Application Description, Claims, Abstract, and Drawings Used for U.S. National Stage
Note:
If the international application is published in English, the Office will use the description, claims, abstract, and drawings as published in the pamphlet for the U.S. national stage application under 35 U.S.C. 371.

The cover page is important as a source of the correct application data, most importantly the filing date and priority date accorded to the international application. If the international application is published in English, the Office will use the description, claims, abstract and drawings as published in the pamphlet for the U.S. national stage application under 35 U.S.C. 371. The description, claims and drawing parts of the international application reflect the application subject matter on the international filing date and are important for comparison with any amendments to check for new matter. The search report reflects the International Searching Authority’s opinion regarding the prior art.

Abstract Not Required on Separate Sheet for Published International Application
Note:
The abstract does not need to start on a separate sheet if it appears with the cover page in the published international application.

The abstract is reproduced on the cover page of the publication, even though it appears on a separate sheet of the international application in accordance with PCT Rule 11.4(a). The requirement of 37 CFR 1.52(b) that the abstract “commence on a separate physical sheet or electronic page” does not apply to the copy of the published international application communicated to the designated Offices by the International Bureau under PCT Article 20. Accordingly, it is improper for the examiner of the U.S. national stage application to require the applicant to provide an abstract commencing on a separate sheet if the abstract does not appear on a separate sheet in the publication of the international application. Unless the abstract is properly amended under the U.S. rules during national stage processing, the abstract that appears on the cover page of the published international application will be the abstract published by the USPTO under 35 U.S.C. 122(b) and in any U.S. patent issuing from the application.

Examiner May Adopt IPEA/ISA Patentability Report in National Stage
Note:
The examiner can use any part of the patentability report from the International Preliminary Examining Authority or International Searching Authority during the national stage, as long as it aligns with U.S. practice.

The examiner may adopt any portion or all of the report on patentability of the IPEA or ISA upon consideration in the national stage so long as it is consistent with U.S. practice. The first Office action on the merits should indicate the report on patentability of the IPEA or ISA has been considered by the examiner. The indication may be a mere acknowledgement.

Annexes May Vary in National Stage
Note:
If the international application was extensively amended, multiple versions of description, claims, and drawings may exist in the U.S. national stage application file.

The IPER may include annexes, i.e., amendments to the international application that were made during the international phase. See MPEP § 1893.01(a)(3). These annexes will be placed in the U.S. national stage application file. Consequently, if the international application has been extensively amended during the international stage, there may be a number of different copies of the description, claims and drawings present in the national stage application file. The IPER may be consulted in Box No. I “Basis of the report” to determine what pages the report was based upon.

Unless proper and timely translations are furnished by the applicant, foreign language annexes will be considered canceled. See MPEP § 1893.01(a)(3). All replacement sheets in the international application are marked with the international application number and the date of receipt in the upper right-hand corner. Replacement sheets that contain changes in format only and are accepted by the receiving Office are marked as “SUBSTITUTE SHEET” at the bottom of the page. Replacement sheets that contain a rectification of an obvious error or mistake and are accepted by either the ISA or the IPEA are marked as “RECTIFIED SHEET (RULE 91)” at the bottom of the page. Sheets that were incorporated by reference and accepted by the receiving Office are marked as “INCORPORATED BY REFERENCE (RULE 20.6).” Additionally, replacement sheets to the claims submitted to the International Bureau as Article 19 Amendments will be marked as “AMENDED SHEET (Article 19)” at the bottom of the page. Furthermore, replacement sheets to the description, claims and drawings submitted to the IPEA as Article 34 Amendments will be marked as “AMENDED SHEET” at the bottom of the page. The IPER will indicate in “Box No. I Basis of the Report” that claim numbers submitted under either PCT Article 19 or 34 have been considered and will indicate the date they were received and the replacement sheets will be annexed to the IPER. The NOTICE OF ACCEPTANCE OF APPLICATION UNDER 35 U.S.C. 371 AND 37 CFR 1.495 (Form PCT/DO/EO/903) should also be consulted, as it will indicate if the annexes or their translation have not been entered.

Basis of Report Must Be Determined Using IPER
Note:
The report must reference specific pages in the International Preliminary Examination Report to ensure accurate examination during the U.S. national stage.

The IPER may include annexes, i.e., amendments to the international application that were made during the international phase. See MPEP § 1893.01(a)(3). These annexes will be placed in the U.S. national stage application file. Consequently, if the international application has been extensively amended during the international stage, there may be a number of different copies of the description, claims and drawings present in the national stage application file. The IPER may be consulted in Box No. I “Basis of the report” to determine what pages the report was based upon. Using the IPER as a roadmap of what happened during Chapter II examination will help determine which version should be examined.

Notification of Withdrawal Must Appear on Specific Forms
Note:
The indication of withdrawal must appear on a Notification of Withdrawal (PCT/IB/307 or PCT/RO/136), a Notification that International Application Considered to Be Withdrawn (Form PCT/RO/117), or other notification.

If the national stage application papers include an indication that the international application or US designation has been withdrawn, then the application should be brought to the attention of the International Patent Legal Administration to determine whether the withdrawal occurred prior to completion of the requirements under 35 U.S.C. 371(c). If the withdrawal occurred prior to completion of the requirements under 35 U.S.C. 371(c), then entry into the U.S. national stage is prohibited. See 35 U.S.C. 366. The indication of withdrawal may appear on a Notification of Withdrawal (PCT/IB/307 or PCT/RO/136), a Notification that International Application Considered to Be Withdrawn (Form PCT/RO/117), or other notification.

Correct Application Data Must Be on Cover Page
Note:
The cover page must include the filing date and priority date for the international application, which are crucial for the U.S. national stage application.

The cover page is important as a source of the correct application data, most importantly the filing date and priority date accorded to the international application. If the international application is published in English, the Office will use the description, claims, abstract and drawings as published in the pamphlet for the U.S. national stage application under 35 U.S.C. 371. The description, claims and drawing parts of the international application reflect the application subject matter on the international filing date and are important for comparison with any amendments to check for new matter. The search report reflects the International Searching Authority’s opinion regarding the prior art.
