PCT Electronic Data Exchange

Through the PCT Electronic Data Interchange (PCT-EDI) system, industrial property offices (IPOs) and WIPO can exchange large volumes of documents related to PCT international applications over the Internet in a fully automated “system to system” manner.

For IPOs of PCT member states that do not have a local automated system for processing PCT international applications, reference is made to the ePCT portal system for offices where it is possible to process PCT international applications without the need for a local automation system.

More about PCT-EDI

Procedures

The PCT-EDI system is based on a simple file management procedure using folders held on a secure file transfer protocol server.

Documents

  • Procedures for sending/receiving document batches PDF, Establishing and using PCT-EDIT
  • Minimal specification for transmitting documents to the IB PDF, data format specifications
  • Annex F of the PCT Administrative Instructions
  • From offices to the IB – participating offices send documents required by the PCT procedure--such as record copies, receiving office forms, priority documents, international search reports, international preliminary examination reports, etc.,--and national phase information using PCT-EDI.
  • From IB to offices:
    • Forms and attachments are distributed to offices using PCT-EDI.
    • Third party observations filed and related documents filed are distributed to offices using PCT-EDI.
    • Supplementary search reports and related documents are distributed to offices using PCT-EDI.
  • From IB to ISA offices – Search copies of international applications and related documents for international search are delivered to offices using PCT-EDI. The eSearchCopy system sends search copies on behalf of any receiving office that chooses to participate in the eSearchCopy system to participating ISA offices via PCT-EDI.
  • From IB to SISA offices – Documents and IB forms for supplementary international search are delivered to offices using the PCT-EDI.
  • From applicants to offices – Post filing documents to be sent from applicants to offices can be sent using ePCT; for offices that have local PCT processing systems these documents are sent using PCT-EDI.

Security

PCT-EDI is based upon the Secure Shell File Transfer Protocol (SFTP). 

Secure Shell, or SSH, provides a secure means of reliably transferring data over communications networks via SFTP. Unlike the standard Internet File Transfer Protocol (FTP), user authentication information is never transmitted in the clear.

All communications are encrypted using a user-selected data encryption algorithm.

Unlike Transport Layer Security (TLS) enhanced FTP, only a single port is used for bi-directional communications, eliminating some rather difficult firewall and security configuration issues. Unlike Hypertext Transfer Protocol (HTTP), SFTP provides asynchronous, block-oriented data transfer verification, including the facility to restart interrupted transmissions from the point of interruption. Unlike Simple Object Access Protocol (SOAP), no independent software development is required. It should be noted, however, that Offices desiring to develop customized SSH/SFTP applications for integration with existing systems may do so.

SFTP makes use of public/private key pairs to authenticate users and services, and to encrypt the stream of data between the client and server. The PCT-EDI supports multiple keys (and thus multiple users) per office account, with user-level account management being under control of the national office.

Current Server Key Fingerprint. Your SSH/SFTP client may prompt you to accept a server key. Please verify the certificate information associated with this link; should you have any questions, please contact us. If you are satisfied with the validity of the link certificate information and the key fingerprint information on that page matches the fingerprint information presented by the server, you may accept the certificate.

National offices are free to select the encryption algorithm and key lengths of their choice.
