1. Act of Unfair Competition | Definition and Significance

Unfair competition refers to an act that unjustly uses the achievements, reputation, or competitive position of another, or that causes damage.
The types of unfair competition established under the Unfair Competition Prevention and Trade Secret Protection Act (hereinafter the 'Unfair Competition Prevention Act') are regarded as acts that go beyond mere imitation and infringe on the fairness and creativity of the market.
A company should accurately understand and respond to this Act in order to protect intangible assets such as technology, brands, and know-how, and to maintain a fair competitive order.
The Unfair Competition Prevention Act is a law enacted for the purpose of creating a fair competitive environment for industrial development and protecting technological innovation. It has the purpose of protecting rights holders and consumers from unfair acts between competitors, and of encouraging creative business activity.
It is important for a company to strengthen its competitiveness by using differentiated trademarks and product designs, but it must not compete by unfair means or imitate what belongs to other companies.
For unfair competition, this firm offers solutions tailored to the client's needs, including preventive consulting, early-stage response to disputes, and negotiation know-how, and an attorney experienced in intellectual property rights reviews the case as a whole.
2. Act of Unfair Competition | Types

The acts of unfair competition under the Unfair Competition Prevention and Trade Secret Protection Act include the following types.
2. Acts causing confusion as to the source of a business
3. Acts diluting a well-known trademark
4. Acts inducing misconception
5. Improper use of a trademark by an agent
6. Acts of wrongfully acquiring a domain name
7. Acts imitating the form of goods, among others
Acts Causing Confusion as to the Source of Goods
This refers to the act of using an indication that signifies another person's goods, or a similar indication, so as to cause ordinary consumers to mistake the goods for those of another person.
Representative examples include imitating a trademark or logo, or using packaging or names with an appearance similar to the genuine product.
This is regulated as unfair competition because it causes confusion among consumers as to the source of the goods.
Companies may need to continuously monitor whether products similar to their own brand are being used in the market.
Acts Causing Confusion as to the Source of a Business
This is an act that causes confusion as to the entity behind a business and imitates another person's trade name, signboard, advertising name, website domain, or the like, or uses a similar name, thereby causing customers to confuse it with the business of a particular company.
It frequently occurs through online marketing, offline signboards, app store registration names, and the like.
Because it is particularly frequent in the franchise industry and in online platform services, it is important to conduct a prior search for the use of similar names and to have a legal response system in place.
Dilution of a Well-Known Trademark
This is the act of using another party’s widely known trademark or identification mark identically or similarly, thereby damaging the reputation and originality of that trademark.
Even if it does not cause confusion as to the source, it results in weakening the distinctiveness and identifying power of the trademark.
Marketing that implies or evokes an association with a famous brand, the setting of keyword advertising, and similar conduct fall under this category.
A company should monitor and take legal measures so that its famous trademark is not diluted by a third party.
Acts Causing Misunderstanding
This is the act of making false or exaggerated labeling or advertising regarding the place of origin, ingredients, manufacturing method, function, and the like, so as to cause consumers to perceive the product differently from reality.
For example, an expression such as "100% domestic raw materials" becomes a problem when it differs from the facts, and such conduct also occurs frequently in social media advertisements, sponsored content on YouTube, and false reviews.
Because the Act on Fair Labeling and Advertising may also apply concurrently, companies should establish internal content production guidelines, and verification of the accuracy of labeling should be carried out first.
Improper Use of a Trademark by an Agent
This is the case where an agent, distributor, contract manufacturer, or the like who used a trademark with the permission of the trademark holder continues to use the trademark without authorization even after the contract has ended.
In this case, consumers are likely to still mistake the goods for genuine products, so it is recognized as unfair competition.
At the time of contracting, it is important to specify the scope of use of the trademark and the prohibition of use after the contract ends, and to take follow-up measures such as recovering the trademark upon actual termination.
Bad Faith Acquisition of Domain Names
This refers to the act of preempting a domain that is identical or similar to another person's trademark, trade name, or personal name, thereby preventing the legitimate rightholder from using that domain.
Subsequently demanding monetary compensation or using a similar brand to draw search traffic also becomes a problem.
Before launching a new brand, a company should always check whether the domain has already been taken and secure key domains in advance, and when a domain dispute arises, it can respond through the procedures of the Korea Internet & Security Agency (KISA).
Acts of Imitating the Form of Goods
This refers to the act of substantially imitating the ‘form’ of another party's goods, such as the external appearance, packaging design, or UI layout, and producing or selling similar goods.
Even if the goods in question are not a registered design, the act may be deemed unfair competition if it causes external confusion between the two products from the standpoint of ordinary consumers.
Recently, the scope of protection has been broadening to include app screen layouts, package color combinations, and similar elements, and a company should secure a differentiated design and concept from the early stages of product development.
3. Act of Unfair Competition | Disadvantages upon Detection
The disadvantages arising from unfair competition are divided into civil, criminal, and administrative sanctions, and they can cause enormous losses from the company's standpoint.
The main disadvantages are summarized below.
Arising of Liability for Damages
For the loss suffered by the harmed company due to an act of unfair competition, the infringing company bears liability for damages.
In this case, the amount of damages may generally be calculated by selecting among the difference in profit and loss, an amount equivalent to a royalty, or the infringer's profit.
Because there are provisions presuming the amount of damages and punitive damages (up to three times), the amount of compensation may increase significantly.
Orders to Prohibit Sales and Recall Products
A court may order, with respect to goods, advertisements, packaging, and the like involved in an act of unfair competition, measures such as a prohibition on sale, suspension of advertising, removal of displayed items, and recall of inventory.
This halts a company's production and distribution lines and causes significant distribution losses.
A blow on the level of a suspension of business may become a reality.
Damage to Creditworthiness and Brand Image
If a company becomes embroiled in a legal dispute over unfair competition, its credibility may decline sharply, and its relationships with consumers and business partners may be damaged.
In particular, if an unfair competition case is disclosed through the internet or media reports, considerable time and cost may be required to restore brand value.
Criminal Punishment
When an act of unfair competition is detected, the following penalties are imposed.
Act | Level of punishment |
Overseas leakage of a trade secret | Imprisonment for up to 15 years or a fine of up to 1.5 billion won |
Domestic leakage of a trade secret | Imprisonment for up to 10 years or a fine of up to 500 million won |
| Registering, holding, or transferring another person's trademark or the like without authorization | Imprisonment for up to 3 years or a fine of up to 30 million won |
| Disclosing a secret learned in the course of duty | Imprisonment for up to 1 year or a fine of up to 10 million won |
Liability may also be attributed to a representative or an individual employee, so the legal risk is significant.
Administrative Sanctions Including Restrictions on Bidding for Government and Public Institutions
If unfair competition is confirmed in the course of cooperation with a public institution or a large company, a business may suffer disadvantages in public bidding or have a partnership terminated.
In particular, the Public Procurement Service, local governments, and public institutions often manage businesses engaged in unfair competition on a blacklist.

4. Act of Unfair Competition | Corporate Prevention and Response Measures

It is advisable for companies to prevent unfair competition and to prepare measures for responding when unfair competition occurs.
1. Conduct advance risk assessment and internal training
To reduce risks such as the leakage of trade secrets by departing employees or external partners and the development of products that imitate other companies' trademarks, a company-wide culture of raising risk awareness and focusing on prevention is needed.
Response measure: Conduct IP training at least once or twice a year, carry out a trade secret awareness assessment survey, and keep records of training completion
2. Secure intellectual property rights in advance and systematize their management
In particular, product designs and brand names are easily targeted for imitation, so the securing of the relevant rights should be completed before launch.
Response measure: Create in-house guidelines for trademark application, design registration, and copyright registration procedures, and embed an IP review at the product planning stage
3. Establish trade secret protection measures
To receive protection, the requirements of ‘non-public availability, economic usefulness, and management as a secret’ required by law must be met, so the practical establishment of a secret management system is key.
Response measure: Mark confidential materials as ‘confidential,’ restrict access rights, obtain pledges from departing employees, and put in place management rules such as external security policy manuals
4. Specify legal safeguards in contracts
Response measure: When reviewing contracts, review the clauses relating to unfair competition through the advice of the legal team or an outside expert
5. Check IP risks in advance for new products and marketing
Response measure: Conduct advance searches for similar trademarks, monitor designs and packaging in advance, and make use of consulting by an external IP expert
6. Monitor competitors' imitation and secure evidence
For matters such as the distribution of similar products, the preemptive registration of domains, and the unauthorized use of advertising keywords, evidence should be secured and measures taken immediately.
Response measure: Conduct ongoing monitoring through an internal or external investigation body, and automate the collection of evidence such as captures, receipts, and website addresses
7. Establish a legal response system and a network of experts
To take legal measures such as a provisional injunction, a criminal complaint, and a claim for damages promptly, it is necessary to secure a network of outside experts.
Response measure: Enter into a prior arrangement with an IP-specialized law firm or patent attorney, and put the response process into a manual for when infringement occurs
8. Prepare an in-house code of ethics on unfair competition
In particular, acts by insiders such as the leakage of trade secrets, the enticement of competitors' customers, and the hijacking of domains should be thoroughly blocked.
Response measure: Clarify the grounds for discipline relating to unfair competition, operate an advance pledge system, and establish an internal reporting system
9. Regularly update on industry trends and related legislation
Ongoing collection of information on legislative amendments and a system for sharing it within the company are required.
Response measure: Conduct quarterly IP briefings through the legal and strategy teams, and operate a channel for monitoring related news
10. Make active use of government support systems
Making active use of these can reduce the costs of advance prevention and of responding to disputes.
Response measure: Apply for consultation at the IP Direct Support Center, apply for mediation of design and trademark disputes, and make use of public institutions' infringement monitoring services
