A trademark application deficiency notice in Turkey is the official letter that TÜRKPATENT (the Turkish Patent and Trademark Office) sends when its formal examination finds one of the legal elements of your application missing, and it starts a two-month period for you to remedy the gap (Article 15(1) of Industrial Property Law No. 6769 (SMK)). If the identity details, the representation of the mark, the list of goods and services or the application fee are missing, the filing date moves to the moment the deficiency is remedied; if the deadline passes, the application is removed from processing.
Below you will find what the formal examination checks, the most common types of deficiency, how each one affects your filing date, how the deadline is calculated and how to respond to the notice step by step.
What Is a Deficiency Notice, and How Does It Differ from a Refusal?
A deficiency notice is a letter stating that the application is formally incomplete; it makes no finding on whether the mark can be registered. A refusal is issued at a separate stage, under Article 16 of the SMK, after the mark has been examined on absolute grounds. One says "your file is incomplete"; the other says "this mark cannot be registered for this scope".
The distinction matters in practice. The answer to a deficiency notice is a document, a piece of information or a payment; the answer to a refusal is a reasoned appeal (Article 20). When a deficiency is remedied in time, the file as a rule continues from where it stopped; the most important exception is the shift in filing date explained below.
What Does the Formal Examination Check?
The formal examination means the Office checking the application against Article 3 of the SMK (who is entitled to apply) and Article 11 (the contents of the application). Under Article 11(1) of the SMK, a trademark application comprises:
- (a) An application form containing the applicant's identity details,
- (b) The representation of the mark,
- (c) The list of goods or services covered by the application,
- (ç) Proof that the application fee has been paid,
- (d) Technical regulations, if the application is for a collective or certification mark,
- (e) Proof that the priority claim fee has been paid, if priority is claimed,
- (f) A transliteration into the Latin alphabet of any non-Latin characters in the representation of the mark.
The letters matter a great deal: deficiencies under (a) to (ç) move the filing date, while those under (d) to (f) do not (Article 15(2)). If there is no formal deficiency, the application is fixed as of the date, hour and minute on which it was received (Article 15(1)); if there is one, the filing date is tied either to the original moment of filing or to the moment the deficiency is remedied, depending on its type. An application by a person who falls outside Article 3, meaning someone with no right to apply in Turkey, does not receive a deficiency notice; it is refused outright (Article 15(4)).
The Most Common Types of Deficiency
In practice, most deficiency notices fall under a handful of headings. Each has a different legal basis and a different consequence; identifying which heading you are under when you read the notice also tells you how urgently you need to act.
Identity details, signature and application form
Identity details mean, for an individual, the first name, surname and, for Turkish citizens, the Turkish ID number; for a legal entity, the company name and tax number (Regulation on the Implementation of the Industrial Property Law, the Regulation, Article 3(g)). Missing identity details, a missing signature or a missing application form are among the deficiencies that move the filing date (Regulation Article 8(3)). A typing error in the applicant's name or address, by contrast, is not a deficiency but an error to be fixed through a separate correction request (Regulation Article 21(1)).
Representation of the mark
Failing to submit a representation of the mark, or submitting one that does not meet the requirements, moves the filing date. Under Article 7(9) of the Regulation, if the representation does not meet the requirements, or if the information, representation and descriptions in the application form are inconsistent, a two-month period is granted and the filing date moves to the moment the document remedying the deficiency is received. Typical examples: failing to submit a playable recording for a sound mark, not stating the color code for a color mark, leaving out views for a three-dimensional mark, or uploading an image that does not match the type of mark selected on the form. If the Office finds the representation insufficiently clear, precise and intelligible, it may also request additional information, documents and explanations about the mark (Regulation Article 7(8)).
List of goods and services
There are three distinct situations regarding the list, and their consequences are very different. Failing to specify any list at all moves the filing date (Regulation Article 8(3)). If the list contains a general term or an expression that needs explaining, the Office asks for clarification within two months; in that case the filing date is not affected, but if no clarification is given, the expression is deleted from the list (Article 9(3)). If the list has not been drawn up in line with the Nice classification, the Office may ask for the fee for rearranging the classification list to be paid within two months so that it can make the adjustments; under TÜRKPATENT's 2026 trademark fee schedule this item (02.01.15) is TRY 1,240, and if it is not paid the application is removed from processing (Article 9(4)). We explain how to get the list right from the start in our guide to drafting the goods and services list.
Fee shortfalls
Missing proof that the application fee has been paid moves the filing date. In a multi-class application, a shortfall in the additional class fees does not affect the date; if it is not made up within two months, the application is examined for the classes covered by the fee paid, taking into account the order in which the classes appear on the form and, where you have stated one, your preference (SMK Article 15(3), Regulation Articles 8(4) and 9(5)). The one-month period in the general rule on underpaid fees (Article 161(3)) does not apply to formal-examination deficiencies; here the period is two months. Current amounts should always be checked against the TÜRKPATENT fee schedule, which is updated every year.
Priority document
If you have claimed priority based on a first application filed abroad, you must submit the priority document within three months of the filing date (Article 13(1)); the original document and a Turkish translation certified by a sworn translator are submitted (Regulation Article 6(1)(a)). This period starts from the filing date, not from a deficiency notice. The deficiency only leads to the loss of the priority right; the application continues with its Turkish filing date (Article 15(3)). We discuss what priority gains you in our article on priority rights in trademark registration.
Non-Latin characters and technical regulations
If the representation of the mark contains characters outside the Latin alphabet, such as Cyrillic, Arabic or Chinese characters, their equivalent in the Latin alphabet must be provided (Article 11(1)(f)). This deficiency, like the failure to submit technical regulations for a collective or certification mark, does not affect the filing date; however, if it is not remedied within two months, the application is removed from processing (Regulation Article 8(5)).
Power of attorney
If the application was filed through a trademark attorney and the power of attorney is missing or does not meet the requirements, the attorney is given two months to remedy the deficiency. If it is not remedied by the end of that period, notifications are sent directly to the applicant where the applicant resides in Turkey; where the applicant resides abroad, the application is deemed not to have been filed (Regulation Article 124(3)). We explain why persons residing abroad can only be represented before the Office by an attorney (SMK Article 160(3)) in our article on what a trademark attorney is.
When Does the Filing Date Shift, and Why Does It Matter So Much?
A filing date shift means that the date, hour and minute at which the deficiency is remedied, rather than the moment the application was first submitted, is treated as the filing date (Article 15(2)). Because priority in trademark law is determined by this date, the shift is not a mere calendar issue but a question of who ranks first.
A fictional example: an application for the mark KAHVEVA is filed on 3 March, but no representation of the mark is uploaded. The deficiency is remedied on 20 April and the filing date becomes 20 April. If someone else filed for the same term in the same class on 10 April, theirs is now the earlier application, and they are the party whose filing stands as a bar under Articles 5(1)(ç) and 6(1) of the SMK. What is more, the shifted date depends on the day you remedy the deficiency: using the two-month period to the very end pushes your date a little further back every day.
Outcome Table by Type of Deficiency
The table below summarizes the types of trademark application deficiency, with their legal basis, their effect on the filing date and the consequence if they are not remedied in time.
| Deficiency | Legal basis | Effect on filing date | If not remedied |
|---|---|---|---|
| Identity details, signature, application form | SMK Art. 11(1)(a); Regulation Art. 8(3) | Moves to the moment it is remedied | Removal from processing |
| Representation of the mark | SMK Art. 11(1)(b); Regulation Art. 7(9) | Moves to the moment it is remedied | Removal from processing |
| No list of goods and services at all | SMK Art. 11(1)(c); Regulation Art. 8(3) | Moves to the moment it is remedied | Removal from processing |
| Application fee | SMK Art. 11(1)(ç); Regulation Art. 8(3) | Moves to the moment it is remedied | Removal from processing |
| General term or expression needing clarification | Regulation Art. 9(3) | Does not move | The term is deleted from the list |
| Additional class fee | SMK Art. 15(3); Regulation Art. 8(4) | Does not move | Only the classes paid for are examined |
| Latin transliteration or technical regulations | SMK Art. 11(1)(d), (f); Regulation Art. 8(5) | Does not move | Removal from processing |
| Priority document or fee | SMK Arts. 13(1), 15(3) | Does not move | Only the priority right is lost |
| Power of attorney | Regulation Art. 124(3) | Does not move | If you reside in Turkey, notifications go to you; if abroad, the application is deemed not filed |
When Does the Two-Month Period Start?
The two-month period starts on the date the deficiency notice is served on you. Under Article 160(6) of the SMK, electronic service is deemed made on the date you first access the document and, in any event, at the end of the tenth day after it was placed in the electronic mailbox allocated by the Office. Not opening the notice does not stop the clock; after ten days at the latest, the period starts running on its own. If your contact details are out of date, or no one checks the electronic mailbox regularly, the period can expire without you noticing.
If you work with a trademark attorney, service is made on the attorney and counts as service on you (Article 160(4)); the period runs from the date of service on the attorney. Article 15 of the SMK provides no extension for formal deficiencies. Calculating the last day and putting it in your calendar on the day you see the notice is therefore the cheapest safeguard in the whole process.
How to Respond to a Trademark Application Deficiency Notice
The response to a trademark application deficiency notice is filed through EPATS, linked to the file. The sequence to follow is:
- Read the notice: Note which deficiency is being raised and under which article and paragraph.
- Calculate the last day: Establish the date of service and put the last day of the two-month period in your calendar.
- Assess the date risk: If the deficiency falls under Article 11(1)(a) to (ç), your date will move to the day you remedy it, so aim to remedy it the same day.
- Submit a complete response: Add the requested document, information or clarification to the file; if a fee is due, pay it and submit proof of payment.
- Confirm the record: Check that your response has been entered in the file and whether any new notification has arrived.
We explain how to reach your file in EPATS and where to find the correspondence in our guide to filing a trademark application through EPATS.
Spelling Mistakes and Obvious Errors: How They Differ from Deficiencies
Correcting spelling mistakes and obvious errors means having typing errors or clear mistakes in the application corrected at the applicant's request (SMK Article 11(6)). The difference from a deficiency notice is that you, not the Office, start the procedure, and it is not bound by a deadline.
The limit is clear: correction requests that change the representation of the mark or the list of goods and services are not accepted (Regulation Article 21(2)). That is also why you cannot use a deficiency response as an opportunity to add a new item to the list or update the logo. We cover in detail what can be changed after filing in our article on amending a trademark application.
What Happens If the Deficiency Is Not Remedied in Time?
A deficiency not remedied in time leads, as a rule, to the application being removed from processing (Article 15(3)). Removal from processing means that the application comes to an end before the Office: the file is not examined further, is not published and never reaches registration. The general rule in the law is that fees paid are not refunded unless otherwise provided (Article 161(4)).
Two exceptions are worth remembering: a shortfall in the additional class fees does not bring down the whole application but only leaves the unpaid classes out of scope, and a priority deficiency only costs you the priority right. For an applicant whose application has been removed, the practical route is a new application for the same mark; but that application carries a new date and ranks behind any applications filed in the meantime. We explain the stages a file goes through after the deficiency stage in our guide to what happens after filing a trademark application.
Preventing a Deficiency Notice in the First Place
Most deficiency notices can be prevented by a short check before the application is submitted. The full list of documents to prepare before filing is in our article on the documents required for trademark registration; before you submit, check these five points:
- Do the applicant's identity details match the official records exactly, and for a legal entity, the company name and tax number in the trade registry?
- Is the representation of the mark clear and consistent with the type of mark selected on the form?
- Is the list of goods and services written in the terms of the Office's classification, or does it contain general expressions that will need clarifying?
- Does the fee paid cover the number of classes in the list?
- Are additional elements such as the priority document, the Latin transliteration and the power of attorney ready?
Conclusion
- A deficiency notice is not a refusal; it asks for the file to be completed at the formal examination and starts a two-month period.
- Deficiencies in the identity details, the representation of the mark, the list of goods and services and the application fee move the filing date to the moment they are remedied.
- Deficiencies in additional class fees, the Latin transliteration, priority and the power of attorney do not move the date, but each has its own consequence.
- The period starts on service; electronic service is deemed made at the end of the tenth day at the latest, and Article 15 of the SMK provides no extension.
- If the deadline passes, the application is removed from processing, fees paid are as a rule not refunded and a new application carries a new date.
