How to Register a Trade Mark in South Korea with KIPO

Registering a trade mark in South Korea means securing exclusive rights in one of Asia's most advanced and brand-conscious economies, where filing volumes are high and where unregistered rights are comparatively weak. South Korea operates a first-to-file system administered by the Korean Intellectual Property Office (KIPO), so the date you file usually matters far more than how long you have traded under a name. If you are entering the Korean market, or licensing a brand there, getting a registration on file early is one of the more important protective steps you can take.

This guide walks through the practical stages of a Korean trade mark application, from working out who can apply through to renewal. It is written for businesses and their advisers who want to understand the shape of the process before instructing a representative. South Korea has its own distinctive features, particularly around the Hangul and transliterated forms of a mark and the way examination is conducted, so it pays to plan rather than treat it as a copy of a European or US filing. The timeframes and procedural periods mentioned below are general rather than guaranteed; confirm current details with KIPO or local counsel before you rely on them.

Who can apply

Any natural person or legal entity that uses, or intends to use, a trade mark in connection with goods or services can apply in South Korea. There is no requirement to be a Korean national or to have a Korean place of business in order to own a Korean registration. Foreign companies, individuals and groups all routinely hold Korean trade marks.

South Korea's system is built around first-to-file, which means that ownership generally goes to the first party to file a valid application for an identical or similar mark covering identical or similar goods or services, not necessarily the first to use it in trade. This is a significant point for brands expanding internationally: if you delay, a third party (including a bad-faith filer) can register your mark before you do. Recovering a mark from a squatter afterwards is possible in principle, but it is fact-specific, turns on the available evidence and is generally slower and more expensive than filing first, so the outcome is never guaranteed. South Korea does not require proof of use to obtain a registration, but a registered mark that is genuinely unused remains vulnerable to non-use cancellation, and a specification that is unjustifiably broad relative to genuine commercial intent can attract problems later. Confirm how use considerations apply to your particular filing with local counsel. The practical lesson nonetheless remains to file early.

The local-representative position for foreign applicants

Applicants without an address or place of business in South Korea generally need to appoint a local representative to act before KIPO, typically a qualified Korean patent attorney, who is among the professionals entitled to represent applicants before KIPO on trade mark, patent and design matters. This is the customary route, and in practice almost all foreign applicants file through a Korean representative who manages correspondence, deadlines and any objections raised during examination.

The representative receives official communications, responds to examiner objections and handles the local-language formalities. Because so much of the process turns on accurate Korean-language drafting and on understanding KIPO examination practice, instructing a competent local representative is not merely a formality; it materially affects the quality of your specification and your prospects of a smooth registration. IPEnvoy is not a law firm and cannot act as your representative, but we route applicants to vetted local firms who can. Confirm the current rules on representation, and any address-for-service requirements, with KIPO or your chosen representative, as these can change.

Clearance and searching, including Hangul and transliterated forms

Before filing, run a clearance search to check whether your mark, or something confusingly similar, is already registered or pending for related goods or services. KIPO provides a free public search platform (KIPRIS) covering Korean applications and registrations, and local representatives also use commercial tools. A search reduces the risk of a refusal on the ground of an earlier conflicting right and of a later dispute with an earlier rights holder.

What makes South Korea distinctive is that clearance cannot stop at the Latin-script form of your brand. A mark in Latin script may need to be assessed alongside its Hangul equivalents, because Korean consumers may transliterate or read a foreign brand in Hangul, and similarity is judged through Korean eyes. The phonetic rendering of your brand in Hangul can be just as important as the original, and two marks that look different in Latin script may sound confusingly alike when transliterated. This affects both what you search and what you choose to file. Many brands file the Latin-script mark and a Hangul version, either as separate applications or as part of a considered filing strategy. We cover this in more depth in our note on Korean-character marks, which is essential reading for any foreign brand entering South Korea.

Nice classification at KIPO

South Korea is a member of the Nice Agreement and classifies goods and services under the international Nice classification, with goods in classes 1 to 34 and services in classes 35 to 45. You select the classes that match your actual or intended commercial activity and list the specific goods or services within each.

In practice, KIPO applies its own examination approach to specifications and pays close attention to whether the listed goods and services are appropriately described and whether the breadth of the specification is consistent with the goods and services for which protection is genuinely sought. Overly broad or vague specifications can attract objections, and South Korea has its own conventions about acceptable terms. Your local representative will usually refine the specification to fit KIPO practice rather than copying a specification drafted for another office. Official fees apply and are generally driven by the number of classes, so the scope you choose has a direct cost effect; confirm the current amounts with KIPO or local counsel, as IPEnvoy does not quote fees.

The application and examination stages

Once the specification is settled, your representative files the application with KIPO. The office first checks formalities, then conducts a substantive examination. KIPO examines under the refusal grounds in the Korean Trademark Act, which cover both whether the mark itself is registrable (for example, whether it is descriptive, generic, deceptive or otherwise non-distinctive) and whether it conflicts with earlier marks. A point worth flagging is that KIPO examines for conflicts with earlier rights of its own motion (ex officio), whereas some offices, for example the EUIPO, do not examine earlier-rights conflicts and instead leave them to opposition by the earlier-rights holder.

If the examiner raises an objection, this is communicated through an office action (a notification of grounds for rejection), and you are given a period to respond with arguments or amendments. A well-reasoned response, or a sensible narrowing of the specification, often overcomes an objection. If the examiner is satisfied that the mark is registrable, KIPO publishes the mark for opposition purposes before registration takes effect, and the mark is registered once the prescribed registration fee is paid. For comparison, the examination-then-publication sequence in South Korea can be contrasted with the approaches in our guides to registering a trade mark in the United States and the European Union.

Opposition after publication

South Korea places its opposition window after publication and before final registration. Once an examiner decides the mark is registrable, KIPO publishes it, and any person can file an opposition within a limited statutory period asking KIPO to refuse the registration. This pre-registration, post-publication opposition is a defined feature of the Korean system, so a mark that has passed examination is not yet beyond challenge until the opposition window has run. The exact length of that period is set by Korean law; confirm it with KIPO or local counsel, as procedural periods can change and are easy to miscalculate from outside the jurisdiction.

Separately from opposition, registered marks can be attacked through invalidation and cancellation trials before KIPO's Intellectual Property Trial and Appeal Board (IPTAB), on grounds such as the mark having been registered contrary to the law, or for non-use over a continuous period. IPTAB decisions can themselves be appealed, in the ordinary course to the Patent Court and ultimately the Supreme Court; confirm the current appeal routes and time limits with local counsel. The exact non-use period and the evidential burden are set by statute, so confirm these with local counsel rather than relying on a figure. Non-use cancellation is a real risk for marks that are registered broadly but used narrowly, which is another reason to file specifications that reflect genuine commercial intent. We explain the challenge mechanisms more fully in our piece on KIPO opposition. Anyone relying on a Korean registration, whether as owner or as a party considering a challenge, should take local advice on the exact deadlines and grounds, because these are time-sensitive and fact-specific.

Rough timeline

How long registration takes depends on the office's workload, whether objections are raised and how quickly you respond. Examination pendency varies materially with KIPO's caseload and the complexity of each application; KIPO publishes current average pendency figures, so confirm the expected timeframe with KIPO or your representative rather than relying on a fixed estimate.

If an objection is raised, or if the application is opposed after publication, the overall timeline lengthens accordingly. There are also procedures that can, in some circumstances, accelerate examination where particular conditions are met, and a local representative can advise whether your situation qualifies. Build a realistic buffer into any commercial plan, such as a product launch, that depends on the registration being in place.

Renewal in general terms

A Korean trade mark registration runs for a fixed term and can be renewed indefinitely for further terms, provided you pay the renewal fee within the prescribed window. The registration is a property right that you maintain by renewing it on time; if you miss the deadline, there may be a limited grace period, but letting a registration lapse can mean losing the mark and having to start again, with the first-to-file risk that implies. State the renewal period generically and diary the date carefully, or have your representative manage it.

Renewal in South Korea does not generally require fresh proof of use at the point of renewal in the way some other systems demand, though a registration that is not genuinely used can still be challenged separately. Confirm the current renewal term, deadlines and any grace-period rules with KIPO or local counsel, as these are precisely the kind of details that change and that this guide deliberately does not state as fixed.

Direct filing versus the Madrid Protocol

You can protect a mark in South Korea in two main ways. The first is a direct national filing with KIPO, as described above, usually through a local representative. The second is to designate South Korea through an international registration under the Madrid Protocol, filing a single international application based on a home registration or application and adding South Korea as one of the designated territories.

Each route has trade-offs. A direct national filing gives you a specification drafted specifically for KIPO practice from the outset and a local representative engaged from day one, which can be an advantage given South Korea's particular approach to specifications and to the Hangul and transliterated forms of a mark. The Madrid route can be more efficient if you are filing in several countries at once and want centralised management and renewal, though if KIPO raises an objection you will usually still need a local representative to respond. Note too that for an initial period after registration the international registration remains dependent on the home application or registration (the central-attack risk), so if the home right falls away the Korean designation can be affected; confirm the current dependency period and its effect with local counsel. Many brands entering several Asian markets weigh South Korea alongside India and Türkiye; our guides to registering a trade mark in India and Türkiye follow the same structure and may help you compare.

A note on using this guide

This page is general information, not legal advice, and IPEnvoy is not a law firm and does not carry out regulated legal work. Korean trade mark practice involves procedural deadlines, language-specific assessment and office conventions that are easy to get wrong from outside the jurisdiction. Before you file, oppose, renew or rely on any deadline mentioned here, confirm the current position with KIPO's official website or instruct a qualified Korean IP professional. IPEnvoy can connect you with vetted IP firms in South Korea to handle the work properly.
