The Basic Principles of Comparative Advertising Under Turkish Law

Comparative advertising is a marketing strategy that highlights the advantages of a product or service by referencing or comparing it with competitors. While widely used globally, the legal framework regulating comparative advertising in Turkey imposes strict conditions to prevent unfair competition. In this article, ER&GUN&ER Turkish Law Firm, a prominent Istanbul Lawyer Firm, outlines the key rules, principles, and legal risks associated with comparative advertising under Turkish law.

Legal Framework Governing Comparative Advertising

Comparative advertising is regulated under Article 8 of the Commercial Advertising and Unfair Commercial Practices Regulation. Key principles include:

  • Advertising must not be deceptive or misleading
  • Comparisons must involve goods/services fulfilling the same needs
  • Comparative claims must be verifiable, objective, and based on measurable data
  • No unfair disparagement or discrediting of trademarks, brand names, or products
  • Price comparisons must be clear and based on the same quality standard

Comparative Advertising in Turkey vs Other Countries

In countries like the U.S., Canada, or Australia, comparative advertising is more permissive and often used aggressively in the market. However, in Turkey, its use has historically been restricted due to concerns about brand reputation and consumer protection. Recent regulations have softened these restrictions, allowing comparative ads under specific legal conditions—provided they remain fair and evidence-based.

Key Components of Comparative Advertising

  • Clear Comparison: Advertising must compare material and relevant product features
  • Truthfulness: Claims must be true and supported by objective data (e.g., scientific tests)
  • Legal Compliance: Ads must comply with advertising, consumer protection, and intellectual property laws

Challenges and Risks

While comparative advertising can offer a competitive edge, it can also lead to legal disputes. Potential risks include:

  • Lawsuits for unfair competition
  • Intellectual property infringement (unauthorized use of trademarks or slogans)
  • Administrative fines from regulatory authorities

Ethical Considerations

Comparative ads must be respectful and avoid defamation. Misleading or aggressive comparative advertising can result in reputational damage and legal consequences. Brands are encouraged to pursue ethical marketing strategies aligned with consumer trust.

Comparative Advertising and IP Law

Comparative ads often involve references to trademarks, brand names, or patented technologies. According to Turkish intellectual property law, such references must not infringe upon IP rights. To ensure legal safety, businesses should verify:

  • Permission to use registered trademarks
  • No misleading use of logos or slogans
  • Respect for copyright and design rights

To mitigate IP risks, legal review of comparative ads is highly recommended. Our Turkish lawyers at Istanbul Lawyer Firm provide legal consultancy to ensure compliance with both advertising and IP laws.

LOI and MOU vs. Term Sheet

Letters of Intent (LOIs) and Memorandums of Understanding (MOUs) are similar pre-contractual documents. LOIs are often used when expressing intent to enter negotiations, while MOUs summarize mutual understandings without commitment. Unlike LOIs and MOUs, a term sheet tends to focus more on financial terms and shareholder rights.
