Note On Informal Communication With The Applicant {PCT-IPEA-428}

PCT/IPEA/428, NOTE ON INFORMAL COMMUNICATION WITH THE APPLICANT (PCT Rule 66.6). This form is used by the International Preliminary Examining Authority (IPEA) under the Patent Cooperation Treaty (PCT). PCT Rule 66.6 allows the IPEA to communicate with the applicant in an informal manner, without the need to comply with certain formal requirements that would normally apply to official communications. This can include, for example, using email instead of traditional mail, or omitting certain formal headings or references. The purpose of the note is to inform the applicant that the communication received from the IPEA is an informal communication under Rule 66.6, and that certain formalities have not been observed. The note also advises the applicant that any response to the communication should be marked as "not for publication," unless the applicant requests otherwise. www.FormsWorkflow.com
