the basis of the first application at the OFF. 

4. Operational procedures for TIPO as the OFF:

application at KIPO with a priority claim may file a request to TIPO for electronic exchange of 
priority document. 
(2) The applicant that makes the request referred to in the preceding subparagraph shall be deemed 
to have agreed that the filing information relating to that application is to be electronically provided 
to KIPO and used as priority document.
(3) The applicant that subsequently files a patent application at KIPO and claims priority on the 
basis of the TIPO application may provide a statement that a request for electronic exchange of 
priority document has been made to TIPO in place of the priority document in paper form. 
(4) After receipt of the statement provided by the applicant pursuant to the preceding subparagraph, 
KIPO will proceed with its operational procedures.
