2.2.2
Incorporating missing or correct parts or elements completely contained in the priority document

If the applicant files (a) missing or correct part(s) (i.e. part(s) of the description, part(s) of the claims and/or part(s) or all of the drawings) and/or (a) missing or correct element(s) (i.e. all of the description and/or all of the claims) which has (have) no basis in the priority document, the filing date of the application as a whole will be the date on which the part(s) and/or the element(s) was (were) subsequently furnished, unless the RO accepted the incorporation by reference of the missing or correct part(s) and/or element(s).

However, after the date of receipt of the purported international application, anAn applicant therefore hasdoes have the possibility to furnish parts of the application and/or entire elements which were erroneously omitted without affecting the international filing date by requesting their incorporation by reference to the priority document (see GL/PCT-EPO A-II, 5).

Similarly, an applicant therefore also has the possibility to request the correction of erroneously filed parts of the application and/or entire elements without affecting the international filing date by requesting their incorporation by reference to the priority document. This latter possibility is, however, not available before all ROs. In particular, the EPO acting as RO has notified the IB of the incompatibility of Rule 20.5bis(a)(ii) and Rule 20.5bis(d) with the legal framework under the EPC; see GL/PCT-EPO A-II, 6. This notification does not have any impact on the activity of the EPO as ISA and IPEA, which depends on the decisions taken by the RO with regard to the international application and its filing date (see GL/PCT-EPO B-III, 2.3.3 and GL/PCT-EPO B-III, 2.3.4, and GL/PCT-EPO B-XI, 2.1).

ThisA request for incorporation by reference can only be donefiled before the RO within two months of the date of receipt of the purported international application (or at the invitation of the RO) provided that the priority claim was present at that initial date of receipt and only if the applicant can show that the missing or correct part(s) and/or element(s) was (were) completely contained in the priority document. Missing or correct parts and/or elements which have been accepted under this criterion are considered to be part of the application documents "as originally filed" (see GL/PCT-EPO B-III, 2.3.4 and GL/PCT-EPO B‑XI, 2.1).

If the RO finds that the "completely contained" criterion is not met, the filing date of the application will be the date on which the part(s) and/or the element(s) was (were) subsequently furnished (unless, in the case of missing parts or of correct elements and/or parts, the applicant withdraws the subsequently furnished elements and/or parts). Where the EPO is (S)ISA or IPEA, the examiner must check (as far as the documents needed are available) whether the RO's assessment of the "completely contained" criterion was correct.
