Introduction

An applicant may file amendments with a covering letter in response to an opinion, within a prescribed time limit. Under Article 19, only claims may be amended. These sheets are usually identified by ‘AMENDED SHEET (ARTICLE 19)’. Under Article 34, the applicant may amend the claims, the description, and the drawings. These sheets are usually identified by ‘AMENDED SHEET’.

Procedures related to Article 19 and Article 34 amendments

Verification of Article 19 amendments

Article 19 amendments need to be verified as having been received by the International Bureau (IB). If the applicant includes alleged Article 19 amendments with the Demand, check the correspondence file to see if the IB have transmitted these amended sheets to the International Preliminary Examining Authority (IPEA). If not, then check the published WO pamphlet on Espacenet to see if it has been published with amendments (and then check these against the amendments on file). If the Article 19 amendments have not been published with the WO pamphlet, then check with the PCT Unit by email. The PCT Unit will send a query to the IB.

Time limits for filing Article 19 amendments

Article 19 amendments are to be filed within whichever time limit expires later of:

• 2 months from the date of mailing of the International Search Report

• 16 months from the priority date.

However, it should be noted that the amendments will be considered as having been received on time if they are received by the IB after the expiration of the applicable time limit, but before the completion of the technical preparations for international publication (Rule 46.1).

If Article 19 amendments are not confirmed as received within the applicable time limits by the IB, then the examiner should first consult the applicant/attorney regarding the amendments, before deciding to consider the amendments as Article 34 amendments (Administrative Instructions 602(c)).

Disregarded amendments

If the applicant indicates that any amendments under Article 19 are to be disregarded, the IPEA treats those amendments as cancelled and marks the relevant sheets of amendments accordingly.

Amendments submitted with the Demand

Where the applicant has marked the check box in Box No. IV of the Demand that amendments under Article 19 and any accompanying statement are to be taken into account, the IPEA indicates on the last sheet of the Demand whether a copy of such amendments and any accompanying statement were actually submitted with the Demand.

Where amendments under Article 19 were submitted with the Demand to IB, a copy of such amendment and any accompanying statement will be transmitted by the IB promptly after the IB receives the Demand.

If no amendments under Article 19 have been made at the time when the Demand is received by the IB, the IPEA is so informed by the IB.

‘Any amendment’, where new claims are substituted for old, is interpreted as ‘any individual claim’. Where amended claims have been received, then these should have been numbered in accordance with Administrative Instructions 205.

Article 34 amendments

Where the international preliminary examination is to take into account amendments under Article 34, but the applicant failed to submit them with the Demand, the IPEA shall invite the applicant (using form PCT/IPEA/431) to submit them within a reasonable time limit specified in the invitation. Whether the amendments are submitted with the Demand or later, they shall be marked in accordance with Section 602(a)(i) to (iii) and (b) before the file is then forwarded to the examiner (Administrative Instructions 602 and PCT/GL/ISPE/12 at paragraph 18.04). See 6.3.3 The Demand and IPRPII for information about the Demand.

Claims from amendments not covered by search report

Where amendments insert claims not covered by the search report – such as claims for which additional fees were requested by the International Searching Authority but were not paid – the question of novelty, inventive step, and industrial applicability cannot be assessed since there are no documents to consider under Article 33(6). This reasoning is recorded in Box III ‘Non-establishment’ of the opinion/report form (Article 33(6) and PCT/GL/ISPE/12 at paragraph 19.25).

Marking of replacement and substitute sheets

The standard for the marking of replacement and substitute sheets is:

Note: If the amended pages are not numbered, then the file should be sent to the PCT Unit with a note to ask the agent for numbered pages.

New Subject Matter

Amendments to the description and drawings, as well as the claims, must not go beyond the disclosure of the international application as originally filed.

An amendment is impermissible if it introduces subject matter that extends beyond the content of the application as filed. This occurs if the overall change in the content of the application – whether by way of addition, alteration or excision – results in the skilled person being presented with information which was not expressly or inherently presented in the application as filed.  

Inherent new subject matter

The term ‘inherently’ requires that the missing descriptive matter is necessarily present in the disclosure, and that it would be recognised by persons of ordinary skill. Inherency cannot be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient.

Explicit mentioning of new subject matter

The subject matter newly presented may be introduced by explicitly mentioning matter which was either not previously mentioned at all or only implied.

For example, if in an application relating to a rubber composition comprising several ingredients the applicant seeks to introduce the information that a further ingredient might be added, then this amendment should normally be regarded as going beyond the disclosure in the application as originally filed.

However, if the applicant can show convincingly that the subject matter in question would, in the context of the claimed invention, be so well known to the person skilled in the art that its introduction could be regarded as an obvious clarification and, therefore, as not extending the content of the application, it is permissible.

Alteration, removal or addition of text

Alteration or excision of text, as well as the addition of further text, may introduce new subject matter.

For instance, suppose a claimed invention related to a multi-layer laminated panel and the description included several examples of different layered arrangements, one of these having an outer layer of polyethylene. Amendment either to alter the outer layer to polypropylene or to omit this layer altogether would not normally be regarded as permissible. In each case, the panel disclosed by the amended example would be quite different from that originally disclosed and hence the amendment would be considered as introducing new subject matter.

Amendment by the introduction of further examples should always be carefully considered, since prima facie any further example to illustrate a claimed invention may extend the disclosure of the application as originally filed.

For further guidance see PCT/GL/ISPE/12 at paragraph 20.10 et seq.

Note: The above provisions do not apply where a change to the application is for the purpose of rectifying an obvious mistake – see 6.1.17 Rule 91 Obvious Mistakes in Documents.

Handling claims that go beyond the disclosure

Where at least some claims go beyond the disclosure, this observation must be included in a written opinion (form PCT/IPEA/408) and IPRP (form PCT/IPEA/409) at Box 1 Item 4, with reasoning provided in the Supplemental Box of the last sheet.

Where only some claims go beyond the disclosure, no further consideration is made of these claims or other claims in so far as they are appended to those claims (Rule 66.2(a)(iv)).

Where all claims are considered to go beyond the disclosure, the file is to be referred to the supervising examiner immediately to obtain the supervising examiner’s agreement.

Note: It seems that, in any opinion, novelty and other questions should only be addressed to allowable or original claims. This course is not particularly useful where, as is likely, further amendment could overcome the problem. Some discretion may be desirable, but it must be remembered that:

• Further amendments might not be filed, and the examination report can be established only with respect to allowable claims.

• At least one opinion addressing the allowability of the claims should precede the ultimate report.
