Trademark Opposition in Turkey

Homepage » Trademark Opposition in Turkey

Trademark opposition in Turkey is a critical legal mechanism that allows third parties to prevent the registration of conflicting trademarks. Under Turkish Industrial Property Law No. 6769, opposition procedures have become faster, more structured, and evidence-based.

This page provides an overview of how trademark opposition works in Turkey, deadlines, legal grounds, and how trademark owners can protect their rights effectively.

Legal Basis for Trademark Opposition in Turkey

Trademark opposition proceedings in Turkey are governed by Industrial Property Law No. 6769, which entered into force on 10 January 2017 and introduced significant changes to Turkish trademark practice.

Key objectives of the law include:

  • Encouraging genuine use of trademarks

  • Preventing abuse of opposition procedures

  • Accelerating trademark registration timelines

Trademark Examination and Publication Process

Before publication, trademark applications are examined ex officio by the Turkish Patent and Trademark Office (TPTO) for absolute and relative grounds for refusal.

If no refusal grounds are identified during examination:

  • The trademark is published in the Official Trademark Bulletin

  • A 2-month opposition period starts from the publication date

Important: The opposition period was reduced from 3 months to 2 months, making timely action essential.

Who Can File a Trademark Opposition?

During the publication period, any natural or legal person — including manufacturers, producers, suppliers, traders, or consumer associations — may file a trademark opposition, even if they are not a party to the application proceedings.

Grounds for Trademark Opposition in Turkey

Trademark opposition may be based on several legal grounds, including:

  • Likelihood of confusion with an earlier trademark

  • Similarity of goods and services

  • Bad faith, which is now recognized as both:

    • An absolute ground for refusal

    • A valid basis in opposition, appeal, and invalidation actions

Proof of Use Requirement

If the earlier trademark relied upon in an opposition has been registered for more than 5 years, the applicant may request proof of genuine use.

In such cases, the opponent must demonstrate:

  • Actual commercial use of the trademark in Turkey

  • Use for the goods and services claimed

This requirement aims to:

  • Prevent defensive registrations

  • Encourage active trademark use

  • Eliminate abusive opposition practices

Opposition Procedure Before the TPTO

The opposition process includes the following stages:

  1. Filing a written opposition within the 2-month publication period

  2. Submission of supporting evidence and Power of Attorney

  3. Applicant’s counter-statements

  4. Evaluation by TPTO examiners

  5. Issuance of an administrative decision

Failure to submit grounds, evidence, or Power of Attorney at the time of filing will result in the opposition being deemed not filed.

Appeals Against TPTO Decisions

Parties adversely affected by TPTO decisions may file an appeal before the Re-Examination and Evaluation Board of the TPTO.

  • Appeal deadline: 2 months from the notification date

  • Appeals must be filed through the Turkish Patent and Trademark Office

International Trademark Applications Designating Turkey

International trademark applications designating Turkey under the Madrid Protocol are treated the same as national applications.

  • They are examined and published for a 2-month opposition period

  • If protection is refused due to opposition, the refusal is notified to WIPO within the 18-month period
