You can access comprehensive legal-status data free of charge from the Korea Industrial Property Rights Information Service (KIPRIS). For each IP right, KIPRIS offers a chronological list of all legal-status events, including post-grant ones such as fee-payment data or litigation information. Most legal-status events are also shown with an English translation. Furthermore, you can access the Korean patent register in KIPRIS for information on patent lapses, term extensions, transfers of rights, etc.
On the “Searching in databases” section of the EPO’s Asian patent information website, we offer a search guide explaining step-by-step how to retrieve legal-status information from KIPRIS.
