Where there are two or more applicants each applicant must sign the request, or each applicant for whom an agent has been appointed must sign a power of attorney (Box No. IX PCT request form, see point 97
). However, if there is more than one applicant the EPO as receiving Office will not invite the applicant to furnish the missing signature(s) if the PCT request form is signed by at least one of the applicants
. Any designated Office, however, may require the missing signature of any applicant who has not signed the PCT request for that designated state.
