A patent gives its holder the exclusive right to commercially exploit an invention for up to twenty years. In Turkey, patents are administered by the Turkish Patent and Trademark Office (TÜRKPATENT) under the Industrial Property Law No. 6769. Filing a patent application is not simply submitting a form — the strategic preparation of the application, particularly the claims, determines the practical scope of protection obtained.
The Three Requirements
For an invention to be patentable, it must satisfy three conditions:
Novelty (yenilik): the invention must not have been disclosed anywhere in the world before the filing date. A patent application, published article, conference presentation, product demonstration, or even a casual social media post by the inventor before filing can destroy novelty. The single most important rule: do not disclose before you file.
Inventive step (buluş basamağı): the invention must not be obvious to a person skilled in the relevant technical field. A minor modification to existing technology does not qualify.
Industrial applicability (sanayiye uygulanabilirlik): the invention must be capable of being made or used in some kind of industry. Pure theories and mental processes are excluded.
Components of the Application
A complete patent application submitted to TÜRKPATENT must include:
- Application form: identifying the applicant and inventor
- Description (tarifname): a detailed technical description of the invention explaining how it works and how to reproduce it
- Claims (istemler): the legally binding statement of what is protected — the single most critical document in the application
- Abstract: a brief technical summary
- Drawings: required where they are necessary to understand the invention
Why Claims Matter Most
The claims define the boundaries of the patent right. A claim that is too narrow is easy for competitors to design around. A claim that is too broad is more likely to be invalidated by prior art. Drafting claims that are simultaneously broad enough to be commercially useful and narrow enough to survive examination is a specialist task. In most cases, professional patent attorney assistance at this stage pays for itself many times over.
The TÜRKPATENT Process
| Stage | What Happens |
|---|---|
| Filing | Application submitted with fees; filing date assigned |
| Formal examination | TÜRKPATENT checks completeness of documents |
| Search report | Prior art search conducted; results communicated to applicant |
| Publication | Application published in the official bulletin approximately 18 months after filing |
| Opposition period | Third parties have 6 months from publication to oppose |
| Substantive examination | Examined against novelty and inventive step requirements |
| Registration or refusal | Patent granted or refused; refusal can be appealed |
The total timeline from filing to grant typically ranges from two to four years without complications.
International Filing: The Priority Right
Filing a patent application in Turkey creates a priority right lasting twelve months. During this period, you can file in other countries (via the PCT international system or direct national filings) and claim the Turkish filing date as the priority date. This means that disclosures or competing filings that occur after your Turkish filing date do not affect your international applications, provided you file within twelve months.
Patent vs Utility Model
Where the inventive step requirement cannot be clearly met, or where faster and cheaper protection is needed for a shorter lifecycle product, a utility model (faydalı model) may be more appropriate:
| Patent | Utility Model | |
|---|---|---|
| Inventive step required | Yes | No |
| Protection duration | 20 years | 10 years |
| Examination | Full substantive | Formal only |
| Annual fees | Required | Required |
| Strength in invalidity proceedings | Stronger | Weaker |
A utility model is faster to obtain and cheaper to maintain, but provides less robust protection that is more vulnerable to a cancellation challenge.
Frequently Asked Questions
I described my invention to a potential investor last week. Have I lost novelty? Disclosure to a third party without a non-disclosure agreement that was in place before disclosure may have entered the invention into the public domain. In some circumstances, Turkey’s law provides a grace period of twelve months for disclosures made by the inventor — but relying on this is risky, and the safer course is always to file before any disclosure.
Can I file a patent application myself without a patent attorney? You can file directly with TÜRKPATENT. However, the claims document — which determines the actual scope of your protection — requires specialist drafting skill. An application filed without professional assistance often results in claims that are either too narrow to be commercially useful or too broad to survive examination.
How much does it cost to maintain a patent? Annual renewal fees (yıllık ücret) must be paid to keep a patent in force from the third year onward. Failure to pay results in lapse. The fee schedule is published by TÜRKPATENT and increases progressively over the life of the patent.
Do I need to register my patent in each country separately? Yes. Patent protection is territorial. A Turkish patent gives rights only in Turkey. International protection requires separate applications — via the PCT system for broad coverage, or direct filings in individual countries. The twelve-month priority window coordinates these filings.
