PCT Receiving Office Guidelines
Chapter VIII: Missing Parts in the International Application
Processing of Later Received Sheets
199. Where the receiving Office receives sheets pertaining to an international application after the date on which one or more elements referred to in Article 11(1)(iii) were first received, following an invitation under Rule 20.5(a) or without such invitation, the receiving Office determines whether these sheets are furnished to complete the international application or whether the applicant intends to confirm the incorporation by reference of those sheets in accordance with Rule 20.6(a). The second option is not available if the receiving Office has notified the International Bureau under Rule 20.8(a) that Rule 20.6(a) is incompatible with its national law.
