Verification note

Read rights information together with its review date.

All 30 records are a snapshot of items shown as registered in KIPRIS searches reviewed on 2026-08-28. The two early joint patent applications and the Danakka mark were searched again on 2026-08-29 to separately review the rights-holder display then visible in KIPRIS.

This page summarizes public search results and does not replace the official register. Where current ownership, term, annuity payments, transfer, security interests, licenses, cancellation, or expiration matter, the Korean Intellectual Property Office register should be checked again.
