Previously, applicants could file unlimited requests for monthly extensions of the two month time period for responding to office actions in Korea. These extensions have now been limited to four months, i.e. a total time of six months from receipt of KIPO's first office action. If applicants request further extensions, they have to give justifiable reasons. No extension will be granted where the request for examination was filed by a third party. The new rules apply to office actions issued on or after 1 July 2008.
