Priority Document Access Service

Glossary

Term Description
APP Confirmation Date When the applicant comes to the system to confirm the availability of Priority Document.
OFF Office of First Filing (OFF) is the term used to refer to an Office whose digital library holds the copy of a document which is to be accessed by other Offices. This equates to the term "depositing Office" in the Framework Provisions. It should be noted that the term extends not only to the actual Office of First Filing, but to any other Office which holds a verified copy of the relevant document (for example, because it has been filed as a priority document in respect of a later application) and which makes it available through the system. This terminology is used rather than the more exact "depositing Office" because of the wide understanding of the term OFF in the context of the most important actual usage of the system.
OFF Confirmation Date Day when OFF Confirms the availability of Priority Document through the system.  In case of Route A, this day will be when OFF add PDOC to the system and therefore it is prior to APP Confirmation Date.  In case of Route B and C, the Confirmation Date will be greater than APP Confirmation Date.
OSF Office of Second Filing (OSF) is the term used to refer to an Office which wishes to retrieve a copy of a document which is held by an OFF. This equates to the term "accessing Office" in the Framework Provisions. The term is used here because it is in current widespread use to describe the most important (and initially only) usage of this role by an Office dealing with an application which claims priority from an earlier application, the latter being the document to be accessed.
PCT/EDI PCT/EDI is the document exchange system used by WIPO and Offices. It is implemented and operated over SFTP. The Service requests and responses for PDOC exchange operations are structured as XML files. A DTD is made available as version 1-0 (library-transaction-v1-0.dtd). Some sample instances of the XML are given in this document.
PDOC Priority Document
Publicly Available Date Publicly Available Date is the term used to refer to the date when the priority document is accessible to all participating Offices regardless of the setting in the access control list. It can be set by Applicant via the web portal or communicated to the Service by the OFF if some bilateral notification service between WIPO and OFF is available.
TDA Trilateral Document Access (TDA) is the document exchange system used by the Trilateral Offices: USPTO, EPO and JPO. It is implemented as web services and operated over a secure network.
