Industrial Design Registration in Turkey: Scope, Duration and Invalidation Lawsuits

What sets a product apart from its competitors is often not its function but its appearance: the line of a chair, the form of a package, the silhouette of a faucet. In Turkey, the legal route to protecting that visual value runs through industrial design registration. The Industrial Property Law No. 6769 (SMK) grants designs both registered and unregistered protection; yet the scope, the term, and the invalidation action available against a rival registration all follow technical rules worth understanding before entering the market.
Requirements for a Protectable Design: Novelty and Distinctive Character
Article 55 of the SMK defines a design as the appearance of the whole or a part of a product resulting from features such as line, colour, shape, texture or material. To qualify for protection, Article 56 requires two core conditions: novelty and distinctive character.
A design is new if no identical design has been made available to the public anywhere in the world before the application (or priority) date; designs that differ only in minor details are treated as identical. Distinctive character requires that the overall impression the design produces on an informed user differ from that produced by designs previously made available to the public. In this assessment, the degree of freedom the designer enjoyed in developing the design is taken into account. Article 57 grants a grace period: a disclosure made by the designer within the twelve months before the application does not destroy novelty, an essential safety valve for designers who wish to test a product at a trade fair or in the market first.
Registered and Unregistered Design Protection
The SMK offers two coexisting regimes. Unregistered design protection arises automatically upon first disclosure to the public in Turkey, but it protects only against unauthorised copying and lasts a short time. Registered design protection is acquired through an application to and registration with TÜRKPATENT, granting the holder a far stronger, exclusive right against designs that lack distinctive character compared to the protected one. For any product appearance with commercial value, registration is almost always the recommended path.
The TÜRKPATENT Application Process and Multiple Applications
An application comprises the elements listed in Article 61: identifying details of the applicant, a reproducible visual representation of the design, the product name, and designer information. Products are classified under the international Locarno Agreement. A significant convenience the law offers is the multiple application: provided the additional fee is paid and the products (excluding ornamentation) fall within the same Locarno class, several designs may be combined into a single filing. This substantially lowers costs for manufacturers seeking to protect an entire product family or dozens of variations of a collection in one file. Under Article 64, protection begins on the date the application is finalised.
Term of Protection: Five-Year Periods and Twenty-Five Years
Article 69 sets the term of protection for registered designs at five years from the application date. This term may be renewed in successive five-year periods up to a total of twenty-five years. The renewal request, together with the renewal fee, must reach the Office within the six months preceding expiry; if that window is missed, a six-month grace period with a surcharge applies. Unregistered designs, by contrast, are protected for only three years from first disclosure and cannot be renewed.
Invalidation Lawsuits: Grounds and Procedure
A registered design is not untouchable. Article 77 lists the grounds on which a court may declare it invalid: the design failing to meet the novelty or distinctive-character requirements, not fitting the statutory definition, ownership belonging to someone else, the application being filed in bad faith, or the design incorporating the unauthorised use of an intellectual property right. A registration may also be invalidated where a subsequently disclosed identical or similar design has an earlier application date.
Procedurally, Article 78 provides that, as a rule, any interested party may bring an invalidation action. The action is filed within the protection term or within five years following the lapse of the design right, against the person recorded in the register as the design owner. Under Article 79 an invalidation decision has retroactive effect: once final, the protection is deemed never to have arisen. Against rival registrations, this action is the most frequently used legal tool at market entry.
The Overlap of Design, Copyright and Trademark Protection
The same product appearance may benefit from several forms of protection at once. Article 58(3) of the SMK expressly states that design protection does not prejudice copyright protection where the conditions of the Law on Intellectual and Artistic Works No. 5846 are met; an original, artistic design may continue to be protected as a work even after the registration term expires. Likewise, a distinctive product shape can be registered as a trademark, establishing an indefinitely renewable chain of protection. This layered approach keeps a design protected without interruption throughout its commercial life.
For foreign manufacturers and designers entering the Turkish market the practical guidance is clear: file the application before launching the product in Turkey or displaying it at a fair; do not rely on the twelve-month grace period as a reason to delay registration; protect a collection economically through a multiple application; and carefully document the date of the first application abroad in order to claim priority.
Frequently Asked Questions
Is unregistered design protection as strong as registration? No. Unregistered protection covers only copying, lasts three years from first disclosure, and places the burden of proof on the right holder. For designs with commercial value, registration is strongly recommended.
I showed my product at a trade fair — have I lost my right to register? Not necessarily. Article 57 grants a twelve-month grace period running from your own disclosure. If you apply within that window, your fair presentation does not destroy novelty; once it lapses, however, your own product can become prior art against you.
How do I stop a competitor's imitation design? You can bring an infringement action based on your own registration and, if the competitor holds a registration, remove it through an invalidation action under Article 77. The two routes are often pursued together.
Can a foreign company register a design in Turkey? Yes. Foreign natural and legal persons may file with TÜRKPATENT through a Turkish agent and may claim priority based on their first application abroad.
