Administered by the Korean Intellectual Property Office (KIPO) and governed by the
revised Korean Trademark Act (Act No.17728, effective 2021), South Korea adopts a
first-to-file trademark system compliant with the Paris Convention and Madrid Protocol.
Two non-negotiable compliance rules plague overseas brands expanding into the Korean
market: mandatory local Korean IP attorney representation for all non-resident filers
and strict three consecutive years’ domestic commercial use requirement to avoid
trademark revocation. Many cross-border beauty, fashion and electronics brands lose
registered marks permanently due to missing authorized local agents or insufficient domestic
use evidence. This case analyzes a French skincare brand’s cancelled trademark dispute,
clarifies KIPO’s examination standards, and delivers streamlined compliance guidance for global
trademark owners.
Non-resident foreign applicants must appoint a KIPO-qualified Korean IP attorney (Trademark
Act Article 6). Any enterprise or individual without a permanent domicile or business premise within
South Korea cannot independently submit trademark filings, oppositions, renewals or non-use defense
petitions. Unlicensed third-party middlemen have no legal standing to conduct KIPO procedures; all
documents signed by unauthorized intermediaries may be deemed void during post-registration
disputes. A general power of attorney issued to a local Korean attorney is mandatory at the initial
filing stage.
Three-year consecutive domestic commercial use cancellation mechanism (Trademark Act Article 73).
A registered trademark will be revoked if it has not been genuinely commercially used within South
Korea for three uninterrupted years after registration, with narrow exceptions only for force majeure.
Valid local use requires three core proof materials: Korean-printed product packaging/offline
advertising, domestic distributor sales contracts, and formal Korean tax invoices issued to local
purchasers. Pure cross-border parallel import overseas logistics records, overseas social media
promotion, and foreign-only sales cannot satisfy the domestic use threshold.
Fixed 2-month opposition publication window and 10-year registration term. After substantive e
xamination passes, the mark is published for 60 days for third-party opposition; failure to respond to
opposition within the statutory period leads to automatic abandonment. Trademark protection lasts
10 years from registration date, with a 12-month pre-expiry renewal window plus a 6-month
post-expiry grace period with surcharges.
Multi-class single application & priority formal requirements. KIPO accepts multi-class filings under
one application form following the Nice Classification. For Paris Convention six-month priority claims,
foreign applicants must submit certified priority documents with Korean translations within 3 months
of Korean filing; untranslated foreign certificates are rejected outright.
IPTAB two-tier appeal remedy system. If dissatisfied with non-use cancellation or opposition rulings,
applicants may file an appeal with IPTAB within 30 days of receiving the decision; further judicial
review before the Korean Patent Court is available if the IPTAB appeal fails. All appeal materials still
require submission through the designated local Korean IP attorney.
● Appoint a KIPO-licensed local Korean IP attorney before any trademark filing, and reserve a signed
general power of attorney for all subsequent dispute and renewal procedures.
● Systematically archive localized Korean use evidence: domestic retail invoices, Korean-language
packaging, offline store display photos and official distributor cooperation agreements to defend
against non-use cancellation petitions.
● Complete multi-class defensive filings covering core products and adjacent categories before
launching sales in South Korea; conduct free pre-filing conflict searches via the official KIPRIS database
to avoid prior mark conflicts.
● Track registration expiry 12 months in advance to complete renewals within the normal window and
avoid costly grace-period surcharges.
● Retain Korean IP litigation specialists to organize complete use evidence packages and draft formal
defense submissions if facing non-use cancellation petitions.
South Korea’s trademark system relies on the mandatory local agent rule and three-year
domestic use revocation mechanism to regulate foreign brand operations. This French skincare
cancellation case proves unauthorized intermediary filings and incomplete localized use evidence will
trigger irreversible trademark loss. For overseas consumer goods brands targeting the Korean
market, engaging a formal Korean IP attorney, long-term preservation of domestic Korean commercial
use records, and timely renewal management are mandatory safeguards to maintain stable trademark
exclusivity.
