If a new trademark application clashes with your brand, you can challenge it before it ever registers, and the tool for that is an opposition. A trademark opposition in Turkey is a formal objection filed with the Turkish Patent and Trademark Office within two months of the application being published in the Official Trademark Bulletin. Miss that window and the mark usually moves on to registration. This guide explains how to file a trademark opposition in Turkey, the grounds you can rely on, the deadlines, the fees and the mistakes that sink otherwise strong objections.
The fees and timeframes below are current as of the time this article is written. Because official fees and procedural rules change, confirm the exact details with a lawyer before you act.
Trademark Opposition in Turkey: The Short Answer
A trademark opposition in Turkey is a written objection that asks the Turkish Patent and Trademark Office to refuse a published application, and it must be filed within a strict two-month deadline. The process runs under the Industrial Property Law No. 6769, which governs trademarks in Turkey. Once an application passes the office’s own examination, it is published in the Official Trademark Bulletin, and that publication starts the clock. Any interested third party can then file an opposition, set out the legal grounds, attach evidence and pay the official fee. The applicant is given a chance to respond. The Trademarks Department then rules, and either side can appeal. It sounds involved, but each stage is predictable once you know the sequence.
What Is a Trademark Opposition in Turkey?
A trademark opposition in Turkey is the formal procedure that lets a third party stop a pending application from registering by raising legal objections before the Turkish Patent and Trademark Office. It is not a court case. It is an administrative proceeding inside the office, known in Turkish as Türk Patent ve Marka Kurumu, or TÜRKPATENT for short, and it is usually the fastest and cheapest way to keep a conflicting mark off the register.
Think of registration as a two-stage gate. First the examiner checks the application against absolute grounds, such as marks that are descriptive or deceptive. If it passes, the mark is published so that owners of earlier rights can react. A trademark objection in Turkey filed at this publication stage is your formal reaction. Without it, the office will not usually refuse an application on relative grounds, because those grounds depend on your earlier rights, and the office does not enforce them on your behalf. Silence is treated as consent.
Grounds for Trademark Opposition in Turkey
The grounds for trademark opposition in Turkey fall into two broad groups: relative grounds based on earlier rights, and absolute grounds based on the nature of the mark itself. Most oppositions rely on the first group. You cannot simply object because you dislike the mark; you need a legal basis under Law No. 6769. The common grounds include the following.
- Likelihood of confusion. The applied-for mark is identical or similar to your earlier mark, and it covers identical or similar goods or services, so the public could confuse the two.
- Identical mark for identical goods. A later application copies your registered mark for the same goods, which is the clearest case of all.
- Well-known marks. Your mark is well known in Turkey, and the new application would take unfair advantage of it or harm its reputation, even across different goods.
- Earlier unregistered or trade-name rights. You used the sign in trade before the application date and acquired rights that the later mark would infringe.
- Bad faith. The application was filed in bad faith, for example to block a genuine owner or to trade on a known foreign brand.
Absolute grounds can also support an opposition, for instance where a mark is descriptive, generic or misleading. When you plead more than one of these grounds for trademark opposition in Turkey, the office examines each in turn, so a well-drafted opposition sets out every basis that fits rather than betting on a single argument.
The Trademark Opposition Period in Turkey
The trademark opposition period in Turkey is two months, counted from the date the application is published in the Official Trademark Bulletin, and it cannot be extended. This is the single most important date in the whole procedure. If the deadline passes without a valid opposition, the office proceeds toward registration, and your remedy shifts to a costlier cancellation or invalidation action later on.
Because the trademark opposition period in Turkey is short and fixed, monitoring matters. The Bulletin is published regularly, and new applications appear in it long before any certificate issues. Many brand owners set up a watch service so that conflicting filings are flagged within days, leaving enough time to prepare a solid opposition rather than a rushed one. In our practice at Karanfiloglu Law Firm, the most common reason a client loses the chance to oppose is not a weak case but a missed publication that no one was watching for.
How to File a Trademark Opposition in Turkey, Step by Step
Knowing how to file a trademark opposition in Turkey comes down to five concrete steps, each with its own paperwork and each aimed at the Turkish Patent and Trademark Office. The process is document-driven, so preparation counts for more than speed.
- Confirm the deadline and the target. Identify the application number and its publication date in the Official Trademark Bulletin, and calculate the two-month cut-off precisely.
- Build the grounds and evidence. Decide which grounds apply, then gather proof: your earlier registration certificates, evidence of use, sales figures, advertising and, for a well-known claim, wider recognition materials.
- Draft the opposition petition. Prepare a reasoned petition that names the earlier rights, matches goods and services class by class, and argues confusion or the other chosen grounds.
- Pay the official fee and file online. Submit the opposition and its annexes through the office’s electronic system, EPATS, and pay the per-opposition fee before the deadline expires.
- Await notification to the applicant. The office serves the opposition on the applicant, who is given a period to respond, and the file then moves to examination.
Whether a particular ground will succeed depends on the similarity of the marks, the overlap of goods and the strength of your evidence; a lawyer can assess it in a short consultation before you commit to the filing. Getting the classes and the arguments right at this stage is what separates a persuasive opposition from a formality.
What Happens After You File
After you file, the Turkish Patent and Trademark Office notifies the applicant, who may respond and, in some cases, demand proof that your earlier mark has actually been used. If your mark has been registered for at least five years at the filing or priority date of the challenged application, the applicant can request proof of use, and you must then show genuine use for the relevant goods or explain a proper reason for not using it. Failing to meet a valid proof-of-use request can cost you the opposition even where the marks are close.
Once both sides have been heard, the Trademarks Department examines the file and issues a decision, either accepting the opposition in whole or in part, or rejecting it. The losing side is not stuck with that outcome. Either party can appeal to the Re-examination and Evaluation Board, the office’s higher review body, within two months of the decision. The Board’s ruling ends the administrative road. If you are still not satisfied, the next step is a cancellation action before the Ankara Civil Courts for Intellectual and Industrial Property Rights, which sit as the specialist courts for these disputes.
Timeline and Costs
Most oppositions are decided in months rather than weeks, though the exact time depends on the office’s workload and whether the case is appealed. The filing itself must happen inside the two-month publication window, but the decision that follows takes longer. As a rough guide, a first-instance opposition decision often arrives within around six to twelve months, and an appeal to the Re-examination and Evaluation Board can add several more months on top. Treat these as indicative, because processing times shift with caseload.
On cost, it helps to separate the official fee from professional fees:
- Official opposition fee. The Turkish Patent and Trademark Office charges a set fee per opposition, revised each year, and it is payable when you file.
- Appeal fee. A separate official fee applies if the matter goes to the Re-examination and Evaluation Board.
- Translation and evidence costs. Foreign certificates and use evidence often need translation, and well-known-mark claims can require substantial supporting material.
- Professional fees. If you instruct a lawyer or trademark attorney to prepare and argue the opposition, their fee is separate from the office charges.
Because the official fees are updated at the start of each year, treat any single figure you read online as a starting point only, and confirm the current amount before you budget.
Common Mistakes When Filing a Trademark Opposition
A handful of avoidable errors account for most failed oppositions. Each has a straightforward fix.
- Missing the two-month deadline. The trademark opposition period in Turkey is not extendable, so a late filing is simply rejected. Watch the Bulletin and diarise the cut-off the day you spot the application.
- Pleading the wrong classes. Objecting only in your own class, when the risky overlap sits in a neighbouring class, leaves a gap. Compare goods and services carefully across the whole specification.
- Thin evidence of use or reputation. Bare assertions rarely persuade the office. Back a confusion or well-known claim with dated invoices, advertising and market evidence.
- Ignoring a proof-of-use request. If your mark has been registered for at least five years and the applicant asks for proof, silence loses the case. Prepare your use evidence before you file.
- Treating opposition as the last resort. Some owners wait, then try to cancel the registered mark in court, which is slower and dearer. Oppose first while the cheaper administrative route is open.
In our practice at Karanfiloglu Law Firm, the oppositions that succeed are almost always the ones where the evidence was organised before the petition was drafted, not scrambled together after the deadline was already looming.
Summary
Filing a trademark opposition in Turkey is the practical way to stop a conflicting application before it registers, and the whole procedure hinges on one date: the two-month window that opens when the mark is published in the Official Trademark Bulletin. Choose the right grounds, match the goods class by class, back the case with real evidence, and file through the Turkish Patent and Trademark Office before the deadline. If the first decision goes against you, the Re-examination and Evaluation Board and then the Ankara IP courts remain open. Because fees and processing times change, a short review of your specific conflict before you file can be the difference between a clean win and a missed chance.

Frequently Asked Questions
How long do I have to file a trademark opposition in Turkey?
You have two months to file a trademark opposition in Turkey, counted from the date the application is published in the Official Trademark Bulletin. This period cannot be extended, so once it passes the office moves the application toward registration and your only remaining option is a costlier cancellation or invalidation action.
Who can file a trademark opposition in Turkey?
Any interested third party can file, most often the owner of an earlier trademark, an earlier application, a well-known mark or an unregistered sign used in trade. You do not need to be a Turkish company or resident, though foreign owners usually appoint a local trademark attorney or lawyer to file and represent them before the office.
What are the main grounds for trademark opposition in Turkey?
The main grounds for trademark opposition in Turkey are likelihood of confusion with an earlier mark, an identical mark for identical goods, protection of a well-known mark, earlier unregistered or trade-name rights, and bad-faith filing. Absolute grounds, such as a descriptive or misleading mark, can also support an opposition.
How much does a trademark opposition cost in Turkey?
The Turkish Patent and Trademark Office charges a set official fee per opposition, and that fee is revised at the start of each year. On top of the official fee you should budget for translation of foreign evidence and, if you instruct one, professional fees for a lawyer or trademark attorney to prepare and argue the case.
What happens if my trademark opposition is rejected?
If your opposition is rejected, you can appeal to the Re-examination and Evaluation Board within two months of the decision. If the Board also rules against you, the next step is a cancellation action before the Ankara Civil Courts for Intellectual and Industrial Property Rights, which handle these disputes as specialist courts.
Is a trademark objection in Turkey the same as a court case?
No. A trademark objection in Turkey is an administrative proceeding inside the Turkish Patent and Trademark Office, not a lawsuit before a judge. It is generally faster and cheaper than litigation, which is why oppositions are the first line of defence, with court action reserved for appeals or later invalidation.
Can the applicant ask me to prove I use my mark?
Yes. If your earlier mark has been registered for at least five years at the filing or priority date of the challenged application, the applicant can request proof of use during the opposition. You then have to show genuine use of the mark for the goods you rely on, or give a proper reason for not using it, or that ground of your opposition can fail.
