# Who Can Oppose a Trademark Application? > Who can oppose a trademark application? Registered proprietors, earlier right holders, trade name owners, and third parties relying on absolute grounds. - Canonical: https://www.webx.net.tr/en/blog/who-can-oppose-a-trademark-application - Language: en - Last updated: 2026-08-20 - Publisher: Webx Marka Patent ve Fikri Sınai Haklar Danışmanlık A.Ş. (https://www.webx.net.tr/) _Machine-readable copy of the page above. The canonical HTML page is authoritative; fees and regulations may change — check the last-updated date._ --- The right to oppose a trademark application belongs to **"interested parties"** (Article 18 of the Industrial Property Code), and that concept is broader than commonly assumed. Holding a registered mark is *not* a precondition. Opponents fall into two groups, and their burdens of proof are entirely different: - **Those relying on relative grounds (Article 6):** persons with an earlier right, who must prove the existence and the date of that right. - **Those relying on absolute grounds (Article 5):** any third party, asserting not their own right but the unlawfulness of the application. ## Opponents Relying on an Earlier Right ### 1. Registered proprietors The strongest position. A person whose earlier registered mark is similar to the opposed application and whose goods and services overlap may oppose on likelihood of confusion (Article 6/1). One caution: if your mark has been registered in Türkiye for at least five years at the applicant's filing date, the applicant may request **proof of use** (Article 19). If you cannot prove it, your opposition is rejected. ### 2. Earlier applicants The proprietor of an earlier application not yet registered may also oppose. What matters is not registration but the **filing (or priority) date**. How priority operates is explained in [The Priority Right](https://www.webx.net.tr/en/blog/priority-right-in-trademark-registration). ### 3. Owners of unregistered marks and signs Even without registration, a sign you have used in the course of trade and over which you have acquired an earlier right may found an opposition (Article 6/3). The burden of proof on this route is heavy. You must show: - That you used the sign **before the opposed application** - That the use was in the course of trade and functioned as a trademark - That the use exceeded a merely local or limited level Dated invoices, catalogue and packaging images, advertising records and web archive printouts are decisive here. ### 4. Trade name and business name owners A trade name or business name may found an opposition as a sign used in trade. But registration in the commercial registry is not sufficient on its own; it must be shown that the name was **actually used in the course of trade**. The legal distinction is set out in [Trade Name, Business Name and Trademark](https://www.webx.net.tr/en/blog/trade-name-business-name-and-trademark-differences). ### 5. Owners of well-known marks Where, because of the level of recognition reached in Türkiye, use would take unfair advantage of the mark, be detrimental to its repute, or dilute its distinctive character, the proprietor of a well-known mark may oppose (Articles 6/4 and 6/5). This is the only route that crosses class boundaries; but reputation must be proved with concrete data. See [What Is a Well-Known Trademark?](https://www.webx.net.tr/en/blog/what-is-a-well-known-trademark) ### 6. Proprietors facing a commercial agent or representative Where an application is filed in the name of a commercial agent or representative without the proprietor's authorisation, the proprietor may oppose (Article 6/2). The provision applies where a distributor or agent attempts to register the mark in their own name. ### 7. Holders of personality, copyright and other IP rights Applications containing another person's name, trade name, photograph, copyright or any industrial property right may be refused upon the right holder's opposition (Article 6/6). ### 8. Interested parties in collective and certification marks, and lapsed marks Where protection of a collective or certification mark has ended through non-renewal, the earlier right holder may oppose identical or similar applications within three years of expiry (Article 6/7). A comparable protection for unrenewed marks appears in Article 6/8. How these marks work: [Collective and Certification Marks](https://www.webx.net.tr/en/blog/collective-and-certification-marks). ## Those Without an Earlier Right: Absolute Grounds The absolute grounds in Article 5 concern the public interest. Opposing on those grounds requires **no earlier right whatsoever**: - Lack of distinctive character - Descriptiveness — directly indicating the kind, quality or purpose of the goods - Signs used commonly in trade - Deceptiveness - Contrariety to public order or accepted principles of morality - Protected emblems, flags, religious symbols, registered geographical indications In practice this means any business in a sector may oppose the registration of a term common to that sector in the name of a single firm. The full set of grounds is collected in [Why Are Trademark Applications Refused?](https://www.webx.net.tr/en/blog/why-trademark-applications-are-refused) ## Who, on What Ground? A Summary | Opponent | Basis | What must be proved | | --- | --- | --- | | Registered proprietor | Art. 6/1 | Similarity + overlap of goods (and use, if 5 years old) | | Earlier applicant | Art. 6/1 | Priority of filing date | | Unregistered user | Art. 6/3 | Earlier use in the course of trade | | Trade name owner | Art. 6/3 | Actual use of the name | | Well-known mark owner | Art. 6/4, 6/5 | Level of recognition and likelihood of harm | | Proprietor v. agent | Art. 6/2 | The representative relationship and absence of consent | | Personality/copyright holder | Art. 6/6 | Existence of the right and absence of consent | | Any third party | Art. 5 | Unlawfulness alone — no own right required | ## The Deadline Is the Same for Everyone Whoever you are, the period is the same: **two months** from publication of the application in the bulletin. It is a forfeiture period and cannot be extended; see [What Is the Deadline for Opposing a Trademark?](https://www.webx.net.tr/en/blog/trademark-opposition-deadline-in-turkey) If you miss it, the mark registers and the only remaining route is an invalidation action in court. The practical value of the right to oppose therefore depends on regular monitoring of the bulletin: [Trademark Watch and Bulletin Monitoring](https://www.webx.net.tr/en/blog/trademark-watch-and-bulletin-monitoring). ## If You Are Considering an Opposition The prospects of success vary markedly with the type of right you rely on and the evidence you hold. Tell us which ground you are relying on and what you can document, and our [legal protection](https://www.webx.net.tr/en/hizmetler/hukuki-koruma) team will set out the realistic prospects and the evidence list. ## Frequently Asked Questions ### My mark is not registered. Can I still oppose? Yes. If you hold an earlier right over an unregistered mark or another sign used in trade, you may oppose (Article 6/3). But the burden of proof is yours: you must document that the right arose before the opposed application and that the sign was used in the course of trade. ### I have no rights, but the application is plainly descriptive. Can I oppose? Yes. Absolute grounds (Article 5) concern the public interest and opposing on those grounds does not require any earlier right of your own. Lack of distinctiveness, descriptiveness and deceptiveness may be raised by third parties. ### Can I oppose a competitor's application simply because we compete? An opposition must rest on a legal ground. Mere discomfort at competition is not a valid ground; an unfounded opposition will be rejected and the fee is not refunded. ### Can a foreign proprietor oppose an application in Türkiye? If their mark is registered or applied for in Türkiye, they may oppose directly. If they hold no right in Türkiye, special provisions such as reputation (Article 6/4) or the commercial agent rule (Article 6/2) may come into play. ### Someone has registered my name or photograph as a mark. What can I do? Applications containing another person's name, trade name, photograph, copyright or industrial property right may be refused upon the right holder's opposition (Article 6/6). The opposition period is two months from publication. ## Related Resources - [Legal Protection](https://www.webx.net.tr/en/hizmetler/hukuki-koruma): Explains attorney support for bulletin oppositions, appeals against refusals, counter-statements and trademark infringement cases. - [Trademark Watch](https://www.webx.net.tr/en/hizmetler/marka-izleme): Covers monitoring similar applications published in the Official Trademark Bulletin and reporting them before the opposition period ends. - [How to File a Trademark Opposition](https://www.webx.net.tr/en/blog/how-to-file-a-trademark-opposition): How do you oppose a published trademark application?
