Competition is one of the basic elements of commercial life. Businesses competing to offer better-quality products and services, reach a wider customer base and gain a strong position in the market is a natural part of economic life.

However, freedom of competition is not unlimited. Commercial activities must be carried out in line with the rules of good faith, and businesses must not try to gain an advantage over one another by unlawful methods.

Unfair competition (haksız rekabet) means practices that, through conduct contrary to the rules of good faith, harm the economic interests of another business or put them at risk of harm.

The unfair competition provisions of the Turkish Commercial Code (TTK) aim to ensure that competition between businesses continues in a reliable, transparent and honest way.

When Does Unfair Competition Arise?

Unfair competition is not limited to a single type of conduct. As commercial relationships develop, unfair competition practices can also appear in different forms.

A business disparaging a competitor, misleading consumers, taking unfair advantage of another business’s work or reputation, or using trade secrets may be regarded as unfair competition.

The key point here is not only whether the conduct harms a competitor. It is also examined whether an advantage contrary to the rules of good faith in commercial relationships has been obtained.

Misleading Advertising and Commercial Statements

Advertising to promote products or services is a normal part of commercial life. However, using false or misleading information in advertising and promotional activities can cause legal problems.

Sharing false information about competitors’ products, making misleading statements that may influence consumers’ decisions, or making untrue claims of superiority can amount to unfair competition.

With the spread of digital marketing channels in particular, misleading practices in online advertising, social media posts and search engine results have also become more important.

Disparaging a Competitor and Damaging Commercial Reputation

Trying to damage a business’s reputation by making untrue statements about its products, services or commercial activities may amount to unfair competition.

Statements aimed at reducing customers’ trust in a competing business, unfounded allegations or disparaging posts can have serious consequences for commercial reputation.

Uncontrolled posts on social media platforms in particular can cause businesses harm that spreads quickly and is difficult to repair.

Use of Trade Secrets and Customer Information

In the course of their activities, businesses create pricing policies, customer lists, production methods, business models and other confidential commercial information.

Obtaining or using this information without authorisation can directly affect a business’s competitive strength.

In particular, former employees using customer lists, the use of confidential information passed to a competing business, or the sharing of data that qualifies as a trade secret may be examined as unfair competition.

Unfair Competition Online

Today, because many commercial activities are carried out online, unfair competition practices have also moved into the digital environment.

Practices such as using a competitor’s brand in search engines to divert customers, creating fake reviews, posting reputation-damaging content on social media or misusing digital advertising tools may require legal assessment.

In infringements that take place online, screenshots, digital records, internet archives and other electronic evidence are important.

The Relationship Between Trademarks and Unfair Competition

Trademarks are among the most valuable commercial assets of a business. Imitating a trademark or using it in a way that creates confusion among consumers can have consequences under both trademark law and the law of unfair competition.

Taking advantage of another business’s reputation, misleading customers through similar names or visuals, or using the value of a brand without permission may be among the situations that require legal protection.

Lawsuits Available in Cases of Unfair Competition

Businesses harmed by unfair competition can bring different legal claims depending on the nature of the case.

Legal action can be taken to establish that unfair competition has occurred, to prevent it, to stop it, to obtain compensation for the damage caused and, where necessary, to remove its economic consequences.

In some cases, it may also be important to obtain interim measures quickly to stop the conduct that constitutes unfair competition from continuing.

The Importance of Evidence in Unfair Competition Cases

One of the most important issues in unfair competition disputes is proving the unlawful conduct and the resulting damage.

Advertising content, internet records, social media posts, commercial documents, correspondence and technical analyses by qualified professionals can play an important role in resolving the dispute.

In infringements that take place online in particular, securing the evidence in time is important to avoid losing rights.

Preventive Legal Measures Against Unfair Competition

For businesses, one of the most effective approaches is to take protective measures in advance rather than fighting unfair competition after it has occurred.

Protecting trade secrets, confidentiality arrangements with employees, securing trademark rights and managing digital reputation can reduce a business’s competition risks.

In sectors with intense competition in particular, building a strong legal framework helps protect the commercial value of the business.

Legal Assessment of Unfair Competition Disputes

Every unfair competition claim has its own features. When assessing whether conduct is unlawful, the commercial relationship between the parties, the method used, the damage caused and the effect on competition must be examined together.

For this reason, in unfair competition matters not only the incident itself but also its commercial consequences and legal basis must be assessed in detail.

Timely legal action plays an important role in protecting a business’s commercial reputation, customer base and competitive strength.
