Why Trademark Clearance Should Come Before Entering the Korean Market

One of the most common mistakes global companies make when entering the Korean market is focusing on business preparation—such as signing leases for retail locations, launching marketing campaigns, and building distribution networks—without first securing trademark rights.

Even if a company successfully completes its Korean incorporation and complies with Korean tax and corporate law requirements, the entire business may come to a standstill if it later discovers that it cannot legally use its own brand name in Korea. In some cases, companies may even be forced to pay substantial settlement amounts to recover trademark rights that were previously registered by others.

This article explains the key characteristics of Korean trademark law, common forms of trademark preemption and trademark squatting, available legal remedies, and practical measures for preventing such disputes.

1. Key Features of Korean Trademark Law

Failure to understand several basic principles of Korean trademark law can leave a foreign brand vulnerable from the outset.

First-to-File Principle

Korea generally follows the first-to-file principle. In other words, trademark rights are primarily determined by who first files the trademark application with the Korean Intellectual Property Office (“KIPO”), rather than by who first used the mark in commerce.

Accordingly, even if a brand is already well known overseas or has been used globally for many years, the foreign brand owner may face serious difficulties in Korea if it has not secured trademark rights through a Korean filing.

Territoriality Principle

Trademark rights are territorial.

A trademark registered in the company’s home country or in other jurisdictions does not automatically provide trademark protection in Korea. Unless the trademark is separately registered in Korea through KIPO or through an international registration designating Korea, the foreign registration itself generally does not create Korean trademark rights.

Registration Before Actual Use

In Korea, a trademark may generally be applied for and registered even before actual commercial use begins.

This feature creates an opportunity for trademark squatters to monitor promising foreign brands and file applications in Korea before the legitimate foreign brand owner enters the market.

2. Common Types of Trademark Preemption

Foreign companies considering entry into Korea commonly encounter trademark preemption in one of the following forms.

① Unauthorized Applications by Professional Trademark Squatters

Trademark squatters may monitor foreign brands that are beginning to gain popularity and file identical or similar marks with KIPO before the legitimate owner enters Korea.

Their objective is often not to operate a genuine business using the trademark, but to obtain leverage over the foreign company once it decides to enter the Korean market.

They may demand a substantial payment in exchange for assigning the trademark or threaten infringement proceedings if the foreign company refuses to purchase the registration.

② Unauthorized Applications by Korean Distributors or Agents

Another common problem arises where a Korean importer, distributor, agent, or commercial partner registers the foreign company’s trademark in its own name without authorization.

The issue may remain hidden while the commercial relationship is functioning smoothly.

However, once the distribution agreement terminates or the foreign company attempts to appoint a new distributor, the Korean partner may use the trademark registration as leverage, for example by demanding renewal of the distribution relationship as a condition for transferring the trademark.

③ Preemption of Korean Transliteration or Variant Marks

A foreign company may register only its English-language trademark while a third party separately applies for the Korean phonetic transliteration of the same brand.

Because Korean consumers often recognize, search for, and refer to foreign brands by their Korean transliterations, ownership of only the English-language mark may leave the foreign company exposed to infringement claims or significant marketing restrictions involving the Korean version of the brand.

3. Business Risks When a Trademark Has Already Been Registered by Another Party

Entering the Korean market after a third party has secured the relevant trademark can create losses far exceeding ordinary incorporation or tax costs.

Immediate Infringement Claims and Preliminary Injunctions

A prior trademark registrant may seek customs enforcement measures or apply to a Korean court for a preliminary injunction prohibiting trademark infringement.

This can result in imported products being detained by customs or the immediate suspension of sales of products already distributed in Korea.

Excessive Settlement Demands and Loss of Bargaining Power

Trademark squatters may demand tens or hundreds of millions of Korean won in exchange for transferring the trademark.

Foreign companies facing an imminent product launch or market entry often have limited negotiating leverage and may feel compelled to accept commercially unfavorable settlement terms.

Significant Rebranding Costs

If the company cannot recover the trademark, it may have to create a separate brand name for the Korean market and redesign packaging, websites, marketing materials, product labels, and other branding assets.

This can dilute global brand identity and result in the loss of significant marketing investments.

Civil and Criminal Exposure

Selling products bearing another party’s registered trademark without authorization may expose the company to civil claims for damages and, depending on the circumstances, criminal liability under the Korean Trademark Act.

4. Legal Remedies for Recovering a Preempted Trademark

If another party has already registered a company’s trademark in Korea, several legal remedies may be available through the Intellectual Property Trial and Appeal Board and the Korean courts.

Remedy	Trademark Invalidation Trial	Non-Use Cancellation Trial	Unfair Competition Claim
Typical Grounds	Bad-faith filing, unauthorized filing by agent or representative, or other statutory invalidity grounds	No genuine use in Korea for at least three consecutive years without justifiable reason	Unauthorized use causing confusion with another party’s well-known name, mark, or commercial identity
Burden of Proof	Generally on the foreign brand owner seeking invalidation	The trademark owner may be required to prove qualifying use	Generally on the foreign brand owner
Typical Duration	Approximately 8 months to 1.5 years	Approximately 6 months to 1 year	Approximately 1 to 2 years for civil litigation
Practical Strength	Depends heavily on evidence of prior reputation, relationship, and bad faith	Often effective where the registrant has never genuinely used the mark	Usually requires substantial evidence of recognition in Korea

Trademark Invalidation

A foreign brand owner may seek invalidation of an improperly registered trademark where applicable statutory grounds are satisfied.

Potential grounds may include:

Unauthorized filing by an agent or representative:
Where a Korean distributor, agent, business partner, or other related party applied for the foreign company’s trademark despite knowing that the trademark belonged to the foreign company, the registration may be challenged under applicable provisions of Korean trademark law.

Bad-faith filing:
Where the foreign company’s trademark was already recognized among relevant consumers and the applicant filed the mark for an improper purpose—such as obtaining an unfair benefit or causing damage to the legitimate brand owner—the registration may potentially be invalidated.

However, mere evidence that the mark was used overseas may not always be sufficient. Evidence regarding the reputation of the trademark and the applicant’s improper purpose may be important.

Non-Use Cancellation

If a trademark squatter registers a trademark but does not genuinely use it in Korea for at least three consecutive years without justifiable reason, a non-use cancellation action may provide an effective remedy.

This procedure can be particularly powerful against speculative registrants because the trademark owner may be required to produce evidence demonstrating qualifying use of the registered mark.

5. Practical Guide to Preventing Trademark Disputes

Trademark disputes can take a year or longer to resolve and can generate significant legal costs even where the legitimate brand owner ultimately prevails.

For that reason, securing trademark protection before entering the Korean market is generally far more efficient than attempting to recover a mark after it has been preempted.

① Conduct a Preliminary Trademark Search through KIPRIS

As soon as entry into the Korean market is being considered, the company should search KIPO records through KIPRIS or engage a Korean trademark professional to determine whether identical or similar marks have already been filed or registered.

② File Both the English Mark and Korean Transliteration

Foreign companies should consider filing not only the English-language version of the brand but also the Korean phonetic transliteration commonly used by Korean consumers.

This can help prevent third parties from exploiting gaps between English-language and Korean-language branding.

③ Strategically Choose Between Madrid Filing and Direct Korean Filing

Madrid international filing:
A foreign brand owner may use the Madrid System to designate Korea based on its home-country application or registration. This can simplify portfolio management where the company is entering multiple countries simultaneously.

Direct filing with KIPO:
Where entry into Korea is imminent, a direct Korean filing through local trademark counsel may provide greater flexibility in defining goods and services, addressing local examination issues, and considering expedited examination where available.

④ Include Trademark Protection Clauses in Korean Partnership Agreements

Agreements with Korean distributors, agents, OEM manufacturers, and other local partners should expressly provide that all trademarks and related intellectual property rights remain owned by the foreign brand owner.

The agreements should also prohibit unauthorized filings by the Korean partner and provide appropriate remedies, including termination and damages, in the event of a breach.

A Trademark That Is Not Secured in Advance Can Become a Serious Obstacle to Brand Growth

Even a company that fully complies with Korean tax and corporate law may face substantial commercial disruption if it fails to secure trademark protection at the appropriate time.

Trademark preemption can result in significant settlement demands, customs detention of products, injunction proceedings, forced rebranding, and loss of negotiating leverage.

A foreign company entering Korea should therefore conduct an early clearance search, protect both English and Korean versions of its brand, and include robust intellectual property protections in agreements with local partners.

Building a strong trademark protection strategy from the planning stage is one of the most effective ways to safeguard valuable brand assets and establish a stable long-term presence in the Korean market.
