2025.08.04

The Unfair Competition Prevention and Trade Secret Protection Act is a statute enacted to prevent acts of unfair competition that harm the interests of persons engaged in the same line of business. The Unfair Competition Prevention and Trade Secret Protection Act also prohibits acts of trade secret infringement.

1. Unfair Competition Prevention and Trade Secret Protection Act | Concept

Daeryun LLC's explanation of the concept of the Unfair Competition Prevention and Trade Secret Protection Act

The Unfair Competition Prevention and Trade Secret Protection Act was enacted to maintain fair competition among companies operating in the same line of business and to protect the rights and interests of consumers.

Where a company restricts competition with another company by unfair means or causes harm to another company, it may become subject to sanctions under the Unfair Competition Prevention and Trade Secret Protection Act.

The Unfair Competition Prevention and Trade Secret Protection Act provides that a claim for damages may be brought in respect of, among other things, conduct that unfairly restricts another company's participation in competitive activity, and conduct that, for one's own business and in a manner contrary to fair commercial practices or competitive order, makes unauthorized use of the fruits produced by another's substantial investment or effort.

If a complaint or report is filed on the basis of this Unfair Competition Prevention and Trade Secret Protection Act, one must respond immediately in order to defend against punishment and a claim for damages.

As the process of securing objective evidence that can support one's assertions in relation to an act of unfair competition is important, one should obtain the assistance of a specialist attorney who combines experience in handling cases under the Unfair Competition Prevention and Trade Secret Protection Act with specialized knowledge.

It is also a good approach to seek legal advisory on the optimal means of resolution so that the matter may be settled through negotiation or arbitration with the other party.

Purpose of Enacting the Unfair Competition Prevention and Trade Secret Protection Act

The purposes for which the Unfair Competition Prevention and Trade Secret Protection Act was enacted are as follows.

Maintaining a fair trading order

Protecting companies from imitation and misappropriation

Protecting intangible assets such as trade secrets and ideas

Encouraging the protection of new technology and creativity

Reasons Companies Must Comply with the Unfair Competition Prevention and Trade Secret Protection Act

1. Maintaining corporate value through the protection of intangible assets
Today, a company's competitiveness depends heavily on intangible assets such as patents, designs, trade secrets, and brand recognition.

The Unfair Competition Prevention and Trade Secret Protection Act prevents these assets from being imitated, misappropriated, or infringed by other companies.

If a company's internal technology, customer information, business strategy, and the like were not legally protected, competitors could easily imitate them and impede the company's growth.

Compliance with the Unfair Competition Prevention and Trade Secret Protection Act is thus both a defense of assets and a strategy for the company's survival.

2. Securing a fair competitive order
The Unfair Competition Prevention and Trade Secret Protection Act protects a fair market competitive order.

If a company violates the law, its relationship with competitors becomes unfair, which can lead to a decline in its market reputation and, further, to the loss of business partners.

In particular, in the subcontracting, distribution, and franchise industries, compliance with the Unfair Competition Prevention and Trade Secret Protection Act is important alongside the Monopoly Regulation and Fair Trade Act, and reports or litigation arising from unfair transactions are frequent.

3. Preventing civil and criminal liability and financial loss
A violation of the Unfair Competition Prevention and Trade Secret Protection Act is accompanied by various legal sanctions, including criminal punishment, damages, provisional injunctions, and corrective orders.

In practice, conduct such as leaking a competitor's trade secret or imitating the external appearance of a product can lead to consequences such as damages running into hundreds of millions of won or a prohibition on the use of a brand.

Familiarizing oneself with the relevant legislation in advance and putting preventive measures in place has a decisive effect on cost savings and risk avoidance over the long term.

4. Establishing an organizational culture and an internal ethics-management framework
An internal system for complying with the Unfair Competition Prevention and Trade Secret Protection Act is directly linked to strengthening a company's ethical management and compliance management systems.

For example, establishing an employee-invention compensation system, a trade secret management guideline, and an internal whistleblowing system leads, together with legal compliance, to securing employees' trust and to a culture of preventing leaks.

Ultimately, it leads toward reducing risk and protecting the corporate brand.
