Renewed every 10 years, forever.

A registered Korean trademark lasts 10 years; renewal extends that term in additional 10-year increments. Repeated renewals can keep your right alive indefinitely — the foundation of long-term brand value.

Yes. There is no cap on the number of renewals. Global brands like Coca-Cola or Samsung have maintained their trademarks for many decades by renewing on schedule.

Filing is allowed within 1 year before expiration; completion before the expiration date is the recommended path. A 6-month grace period after expiration is available with a surcharge, but missing that window terminates the right — early action is much safer.

Yes. You can select a subset of the originally designated classes for renewal. Classes you choose not to renew lapse, and dropping unused classes is a common way to substantially reduce renewal costs.

The assignment must be recorded at KIPO before you can renew under the new holder's name. If not yet recorded, the assignment must be filed first — iphere can handle both in a single workflow.

Yes. Bulk Excel registration plus checkbox bulk-payment from the list view. Enter only the registration numbers — iphere pulls the mark, classes and expiration date directly from KIPO. Highly efficient for portfolio holders.

KIPO's renewal fee scales with the number of classes. A base statutory fee applies per class, plus the iphere service fee — totals appear on the checkout page automatically. Renewing fewer classes proportionally lowers the bill.

A 6-month grace period applies after expiration. Renewal is still possible with a surcharge during that window. After 6 months the right lapses entirely — you would need to refile from scratch, and a third party may register the same mark in the interim.
