Foreign Corporation Trademark Filing in Korea: Procedures and Costs Practical Guide
Foreign corporations can file for Korean trademark rights regardless of whether they conduct business in Korea, but in practice most applicants get stuck on the mandatory local agent requirement and on classifying designated goods.
This guide is aimed at foreign-invested enterprises that have established a Korean entity, overseas headquarters preparing to enter the Korean market, and foreign businesses planning OEM, distribution, or online sales in Korea.
In the sections below, we walk through applicant eligibility, required documents, examination stages, cost structure, comparison with Madrid international filings, and how to respond to office actions — all in one place.
Conditions Under Which a Foreign Corporation Can File a Korean Trademark
Applicant Eligibility — Corporate Form and Nationality
Foreign corporations may file trademark applications directly with the Korean Intellectual Property Office (KIPO).
The key point is that filing is possible even without a place of business in Korea.
However, foreign applicants without an address or business location in Korea must appoint a domestic agent (a patent attorney, or a patent attorney in cooperation with an administrative scrivener) with an address in Korea, pursuant to Article 6 of the Trademark Act and its Enforcement Decree.
In practice, if you have already established a Korean entity, the first decision is whether to file under the Korean entity's name or under the overseas headquarters' name.
This choice has direct downstream effects on license agreements, assignments, and tax treatment.
Filing Under the Korean Entity vs. the Overseas HQ — What Actually Differs
On the surface this looks like a simple naming choice, but in practice the outcomes diverge significantly.
| Category | Korean Entity Name | Overseas HQ Name |
|---|---|---|
| Agent requirement | Not required | Domestic agent required |
| License handling | Simple domestic contract | International license agreement needed |
| Tax on assignment | Domestic transfer treatment | Cross-border transfer, withholding tax review |
| Dispute response | Direct response via Korean courts/IP Tribunal | Added HQ approval and translation steps |
Practical tip: If the brand will only be used in Korea, filing under the Korean entity is simpler. If the goal is unified global management, a common structure is filing under the HQ with the Korean entity granted a license to use.
The right filing name for your corporate structure cannot be determined by a simple side-by-side comparison.
In a recent matter, the wrong name was chosen at filing, and the trademark had to be re-filed at the licensing stage.
For an accurate determination on naming, please confirm through a consultation.
What You Must Verify Before Filing
Prior Trademark Search — The Most Commonly Skipped Step
The first thing to check is whether identical or similar trademarks are already registered.
A KIPRIS search alone has limitations.
You also need to assess phonetic similarity, visual similarity, and conceptual similarity together.
If this step is weak, office actions follow almost automatically after filing.
Designated Goods/Services Classification (Nice Classification)
A trademark application must specify which of the 45 Nice classes (1 through 45) the protected goods or services fall under.
In practice, defining classes too narrowly leaves protection gaps, while defining them too broadly increases cost and the chance of refusal.
Cosmetics, food, medical devices, and software tend to have especially blurry class boundaries and frequently cause confusion.
| Example Class | Representative Goods | Often Bundled With |
|---|---|---|
| Class 3 | Cosmetics, soap | Class 5 (pharmaceuticals), Class 21 (containers) |
| Class 25 | Apparel, footwear | Class 18 (bags), Class 35 (retail) |
| Class 9 | Software, apps | Class 42 (SaaS), Class 38 (telecom) |
| Class 30 | Processed food, coffee | Class 29 (processed meat), Class 43 (food service) |
Self-Check on Absolute Grounds for Refusal
Marks lacking distinctiveness (generic terms, customary marks, purely descriptive indications) will not be registered.
Marks consisting solely of a place name, common surnames, and simple combinations of numbers or letters are also typically blocked.
If your mark is weak on this dimension, even amendments rarely fix it.
Filing Procedure at a Glance
Overall Flow
- Prior trademark search
- Preparation of applicant information and power of attorney for the agent
- Drafting the application and filing electronically via Patent-Ro
- Formality examination (1–2 weeks)
- Substantive examination (typically 10–14 months)
- Submission of arguments and amendments in response to any office action
- Application publication (2-month opposition window)
- Decision to register and payment of the registration fee
- Receipt of the trademark registration certificate
Time Required at Each Stage
| Stage | Average Duration | Notes |
|---|---|---|
| Application filing | Immediate | Based on electronic filing |
| Formality exam | 1–2 weeks | May require formal amendments |
| Substantive exam | 10–14 months | Can be shortened via accelerated exam |
| Publication | 2 months | Opposition period |
| Decision to register → registration | 1–2 months | After fee payment |
Eligibility for accelerated examination requires specific grounds such as actual use, risk of infringement, or a Madrid basic application.
Whether your case qualifies for accelerated examination should be confirmed in a consultation.
Required Documents
- Proof of applicant identity (foreign corporate registration extract or business registration certificate — apostille or consular legalization may be needed)
- Power of attorney for the agent (Korean or English, signed and sealed)
- Trademark specimen (image file; figurative marks must meet resolution requirements)
- List of designated goods/services
- Priority documents, if claiming priority (within 6 months for treaty member countries)
Note: Foreign corporate documents must typically be issued within a certain period before filing and must come with a Korean translation. Validity periods for these documents can change, so verify them again immediately before filing.
Cost Structure — What Goes Into It
Trademark filing costs break down into three main categories.
- Government official fees (filing fee, registration fee)
- Agent fees (patent attorney / administrative scrivener cooperation fees)
- Ancillary costs (translation, notarization, apostille, specimen preparation)
Costs vary case by case, so exact figures are provided during a free consultation.
In particular, the number of designated classes, the number of items per class, whether accelerated examination is used, and the number of office-action responses can significantly change the total.
Practical tip: The biggest cost driver is the number of classes. Each added class increases both official fees and agent fees, so you should map out your business scope before designing the filing.
Government official fees are subject to change under the KIPO fee schedule notice, so always check the schedule in effect at the time of filing.

Madrid International Filing — When It Is Advantageous
Overview of the Madrid Protocol
The Madrid Protocol allows simultaneous trademark protection in approximately 130 member countries through a single international application.
It is administered by WIPO and is built on top of a Korean basic application or registration.
Korean Filing vs. Madrid — What Actually Differs
| Item | Individual Korean Filing | Madrid International Filing |
|---|---|---|
| Filing unit | Country-by-country | One application designating multiple countries |
| Cost structure | Stacked per country | Basic fee + designation fee per country |
| Dependence on basic application | None | Dependent on basic application for 5 years |
| Renewal management | Fragmented per country | Unified renewal in one step |
| Best for | Entering 1–2 countries | Entering 3 or more countries simultaneously |
The Reverse Case: Foreign HQ Entering Korea
When an overseas headquarters extends a mark already registered in its home country into Korea, designating Korea via the Madrid Protocol is the common route.
In that case, KIPO acts as the office of the designated country and conducts the substantive examination.
If the designated goods do not align with Korea's classification standards, an office action is issued and a response must be filed within the deadline.
Translation and interpretation gaps often cause friction at this point.
Office Actions — The Stage That Most Often Decides the Outcome
Frequently Cited Grounds for Refusal
- Similarity to a prior registered mark (Article 34(1)(7) of the Trademark Act)
- Lack of distinctiveness (Article 33)
- Unclear designation of goods
- Insufficient proof of the applicant's identity
Response Strategy
A focused response that nails down one or two key arguments is typically more persuasive than a lengthy submission.
Amending the specimen, deleting part of the designated goods, and submitting evidence of use should all be considered as part of the response toolkit.
If your response at this stage is weak, the filing fees you paid are effectively sunk.
In practice, more than 90% of cases are decided at the first round of office-action response.
The right response strategy depends on the specifics of the notice, which need to be reviewed alongside the office-action document itself.
Post-Registration Management — As Important as Filing
Duration and Renewal
Trademark rights last 10 years from the date of registration and can be renewed in 10-year increments.
Missing the renewal deadline causes the right to lapse, and during the gap a third party may register the mark first, creating risk for any refiling.
Preparing for Non-Use Cancellation Actions
If a trademark is not used without legitimate reason for three or more years after registration, a third party may file a non-use cancellation action with the IP Trial and Appeal Board.
This is the trap foreign corporations fall into most often.
Evidence of use (advertisements, transaction statements, packaging photos, website screenshots, etc.) should be collected as a matter of routine practice.
Assignment and Licensing
Assignments of trademark rights and the establishment of exclusive or non-exclusive licenses must be recorded in order to be enforceable against third parties.
License structures between an overseas HQ and a Korean entity should be designed alongside tax review to avoid disputes later.
Frequently Asked Questions (FAQ)
Q1. Can a foreign corporation without a Korean office still file a Korean trademark?
Yes.
You must, however, appoint an agent with a domestic address and prepare a power of attorney along with proof of the foreign corporation's identity (including translations).
Q2. Can we file a trademark before establishing a Korean entity?
A common approach is to file first under the overseas HQ's name and then transfer the right to the Korean entity once it is established.
Note that the transfer requires a separate change-of-name filing and triggers its own tax considerations.
Q3. How long does registration take?
Under standard examination, it typically takes 10–14 months.
Accelerated examination can shorten this, but whether your case qualifies needs separate review.
Q4. Should English and Korean versions of the trademark be filed together?
Even for the same brand, the English wording, Korean wording, and logo are treated as separate marks.
If you plan to use the Korean spelling in the Korean market, filing the Korean version as well gives broader protection.
Q5. Madrid international filing or individual Korean filing — which is better?
If you plan to enter only 1–2 countries, individual filings are simpler.
For 3 or more countries, the Madrid route is often more cost-effective and easier to manage.
A tailored comparison based on your expansion plan is provided in consultation.
Q6. Can the trademark be modified after filing?
The mark itself (the sign) generally cannot be changed after filing.
For designated goods, only amendments that narrow the scope are allowed; adding new items requires a separate application.
Need Expert Consultation?
For foreign corporations, the outcome of a Korean trademark filing is decided less by basic eligibility and more by name design, class composition, and office-action response.
Even with the documents in place, weak class design erodes the scope of protection, and a slow response to an office action can sink the filing entirely.
