Patent Application Encyclopedia

KIPO conducts formality examination and substantive examination of invention patent applications. Only after the application documents meet the conditions of formality examination, KIPO will assign the patent to the application number. Publication is completed within 18 months from the filing date/priority date. The applicant/interested party shall submit a substantive examination request no later than 5 years from the filing date. Once an examination request is made, it cannot be withdrawn, and KIPO conducts examination in the order in which the examination requests are filed. Patent applications that meet the grant conditions will be granted.
