Utility Model Protection in Turkey: A Guide for Foreign Product Manufacturers

Turkey’s utility model system protects qualifying technical inventions, but it is not a universal substitute for a patent. Article 142 of Industrial Property Code No. 6769 requires novelty and industrial applicability and excludes specified subject matter, including processes, biotechnology and the listed chemical and pharmaceutical inventions. Article 143 requires a search procedure and provides distinct opportunities for applicant objections and third-party observations. After grant, the patent opposition procedure in Article 99 is unavailable; invalidity is sought in court under Article 144.

For a foreign product manufacturer, the decision is therefore more than choosing a shorter or less expensive filing label. The actual technical subject, the claim scope, publication history and intended enforcement need to be assessed. This guide explains the statutory route and the questions an overseas owner or Turkish importer should address before relying on a utility model certificate.

Novelty and industrial applicability are the starting requirements

Article 142(1) of Code No. 6769 refers to novelty under Article 83(1) and industrial applicability under Article 83(6). It does not reproduce the separate inventive-step requirement used for patents. That distinction does not mean that an existing product can be protected merely by changing its name or selecting an alternative filing category.

Article 142(2) says that technical features making no contribution to the subject of the invention are disregarded in assessing novelty. The claim analysis must therefore identify the technical contribution rather than accumulate irrelevant details to make the wording appear different. Explain what the claimed configuration does and which features matter to that operation.

Prior disclosure must be examined carefully. Obtain dated catalogues, earlier publications and other relevant materials, distinguishing what was publicly available from internal confidential work. A document prepared after filing cannot automatically establish what was disclosed earlier. A foreign product launch can therefore be relevant to the technical-history investigation even though the right sought is Turkish.

A utility model concerns the claimed technical invention, not simply a product’s visual appearance or brand. Design and trademark protection answer different questions. A product portfolio can require more than one type of analysis, but the existence of one registration must not be described as automatically supplying every other form of protection.

Article 142 excludes important categories of invention

In addition to the exclusions in Article 82(2) and (3), Article 142(3) excludes the listed chemical and biological substances and processes and products obtained by those processes; pharmaceutical substances and processes and their resulting products; biotechnological inventions; and processes or products obtained through processes. The precise claimed subject must be classified before the application route is selected.

A manufacturer should not assume that a chemical formulation becomes eligible merely because it is packaged in a physical container. Similarly, describing a manufacturing process as a technical system does not conclusively resolve the exclusion. The assessment must follow the actual claimed teaching, not a marketing description chosen to make the application sound mechanical.

Where the subject is excluded from utility-model protection, assess whether a patent route is available under its own requirements. Exclusion from this particular system is not a general finding that the technology has no legal protection of any kind. Conversely, commercial value does not override the statutory exclusions.

The protection period is ten years from application

Article 101(1) sets utility-model protection at ten years from the application date and states that the period cannot be extended. The grant date does not begin a fresh ten-year term. A purchaser should calculate the remaining period using the correct application record rather than the date printed on a recently issued document.

Article 145(1) applies patent provisions where no express utility-model rule exists and application is consistent with the utility model’s nature. That provision must be used carefully: it does not erase the explicit differences in Articles 142–144. The maintenance and missed-fee guide explains the separate statutory framework for preserving rights and addressing payment failures.

Do not promise a fixed total filing cost or a guaranteed grant timetable without checking the applicable official tariff and the actual procedural record. Search requests, translations, responses and representative work are different items. This guide explains legal requirements rather than quoting an unverified package price.

Foreign-language documents and formalities have separate deadlines

Article 143(1) provides that an application missing any of the minimum elements identified in Article 90(3) is not processed. Paragraph 2 addresses other missing elements under Article 90(1) and elements supplied in a foreign language under Article 90(2). The deficiencies must be completed or Turkish translations supplied within two months from filing without a separate notification being required.

Failure under that paragraph results in the application being treated as withdrawn. A foreign applicant should therefore not wait for a reminder before arranging the necessary Turkish material. Keep the filing receipt, the documents actually submitted and a record of which items remain outstanding.

Article 143(4) concerns a different formal-deficiency stage: where the Office finds non-compliance with formal requirements, the applicant is asked to correct it within two months from notification. Failure then leads to refusal. The two-month filing-based period and the two-month notification-based period must not be merged into one generic deadline.

Technical translations should preserve the relationship between the claims, description and drawings. A translation that changes a limitation or introduces a feature not present in the original can affect the legal analysis. Keep source documents and version-controlled translations so that the response explains what was actually filed.

A search request is required

Article 143(5) permits the search request with the application or within two months from the notification that formal requirements are satisfied or deficiencies were corrected in time, with the fee paid and the implementing requirements met. No further reminder is required. Failure to request the search results in deemed withdrawal.

The search report is prepared, notified to the applicant and published under paragraph 6. This distinguishes the system from an assumption that registration occurs without any review of relevant earlier material. A certificate should not be purchased or relied upon without examining the search history and any issues raised in it.

Under Article 143(7), a report is not prepared where the subject falls within Article 142(3) or the description or all claims lack sufficient clarity to permit the search. The applicant is given three months from notification to submit objections or amendments. Failure to respond, or rejection of the objections or changes, leads to refusal.

Where the response is accepted, the search report is prepared, notified and published. The file should preserve the exact accepted claim text. A commercial summary saying that the application passed review is not enough to show what technical scope remains after the response.

Applicant objections and third-party observations are not the same act

Article 143(8) gives three months from publication of the search report for the applicant to object to its content and for third parties to submit observations, with the relevant supporting documents. The publication date is therefore central. The date a competitor happened to discover the report is not the statutory starting event.

A third party should identify the technical issue and the documents supporting it. A general allegation that the product has existed for years is less useful than a dated disclosure linked to the relevant claim features. Preserve the complete document, its publication evidence and the explanation of its significance.

Under paragraph 9, the Office considers the search report alone if there are no objections or observations, or considers it together with those submissions where they are made. Silence by third parties is not a legal guarantee that no relevant prior art exists. Equally, an observation is not itself a final judicial invalidity decision.

Grant, required amendments and the limits of the certificate

Article 143(10) provides for notification and publication where the Office decides to grant the utility model. Where changes are necessary, the applicant has two months from notification to make them. Accepted changes lead to grant and publication; failure to make them, or rejection of them, results in deemed withdrawal and publication of that result.

After grant publication, the document is issued on request and payment of the document fee. The legal record should distinguish the grant publication from later delivery of a physical or electronic certificate. A delayed request for the certificate should not be confused with a new application date or a fresh protection period.

Article 143(13) expressly states that grant is not an Office guarantee of validity or usefulness and does not create Office responsibility on that basis. Due diligence must therefore examine the claims and history rather than treating the certificate as conclusive proof that the right will survive every challenge.

After grant, invalidity belongs in court

Article 143(11) excludes the post-grant patent opposition procedure in Article 99 for utility models; only court invalidity can be requested through that route. The six-month patent opposition mechanism must not be copied into a utility-model enforcement plan. Refusal of an application has its separate Article 100 objection route under Article 143(12).

Article 144 identifies invalidity grounds: failure to satisfy Article 142, insufficient disclosure under Article 92(1), added subject matter beyond the relevant original application and lack of entitlement under Article 109. Each ground needs its own explanation and evidence. A technical novelty dispute is different from a claim that the registered holder was not entitled to seek the right.

Interested persons, prosecutors and the specified public bodies can seek invalidity, but the entitlement ground is reserved to the inventor or successors. The action can be brought during protection and for five years after the right ends, against the registered holder, with notice to other recorded right holders so they can participate. It is not a five-year period beginning at grant.

Article 144(5) and (6) permit partial invalidity through cancellation of affected claims, prohibit invalidity of only part of a claim and preserve remaining claims that satisfy Article 142. A challenge to one feature does not justify ignoring every other claim. The requested relief should follow the technical case actually established.

Enforcement and double protection require separate review

Article 141 addresses infringement of patents and utility models. A registered utility model therefore has an enforcement framework, but the product comparison and the statutory conditions still matter. Our non-infringement and patent-warning guide explains the importance of claim-based analysis and the distinction between a warning and an existing court case.

Article 145(2) prevents independent multiple patents or utility models, or both kinds of document, being granted to the same person or successor for the same invention with the same scope of protection. The rule should not be simplified into a claim that a company can never own related rights, but identical protection cannot simply be multiplied by changing the filing label.

For an investment or licence, obtain the register, complete claims, search report, objections, observations and accepted amendments. Check ownership and the permission actually offered. Our entitlement guide and technology-licensing guide explain related issues, subject to the utility-model applicability rule. Technical protection, ownership and permission to operate must remain distinct in the final decision.
