A trademark is a sign that allows the goods or services of one enterprise to be distinguished from those of other enterprises. It can be composed of various types of signs, including words (including personal names), shapes, colors, letters, numbers, sounds, and the forms of products or their packaging, provided that the trademark is recorded in a way that clearly and definitively conveys the subject of protection granted to the trademark owner.

The most important criterion related to a trademark is that the sign used must possess a "Distinctive Character" that allows it to differentiate the products or services from similar ones. This distinctiveness is crucial for obtaining and maintaining trademark protection, as it ensures that the trademark serves its primary function of identifying the source of the goods or services.

1. Citizens of the Republic of Turkey: Turkish citizens can apply for trademark registration.

2. Individuals or Legal Entities with a Residence or Business Activity in Turkey: Real or legal persons who have their residence in Turkey or engage in industrial or commercial activities within the country can file for trademark registration.

3. Individuals with Application Rights Under the Paris Convention or the World Trade Organization Agreement: Persons who have the right to apply under the provisions of the Paris Convention or the Agreement establishing the World Trade Organization can also apply for trademarks.

4. Individuals from Countries Providing Trademark Protection to Turkish Citizens Based on Reciprocity: Persons from countries that grant industrial property rights protection to Turkish citizens, in accordance with the principle of reciprocity, may apply for trademark registration.

These provisions ensure that both domestic and foreign entities can seek protection for their trademarks within Turkey, fostering a fair and competitive market environment.

- Trademark registration grants the right to place and use the trademark on the products and services specified in the registration certificate. It enables the owner to utilize the rights outlined in the law, including sending warnings to those who unlawfully use and/or imitate the registered trademark, obtaining injunctions and seizures of products bearing the trademark, and seeking compensation. For the trademark owner to effectively exercise these rights, they should actively monitor their trademark for potential imitations. Additionally, it is advisable to seek trademark monitoring services from trademark agents to identify similar marks published for registration and to exercise the right to object in order to prevent the registration of those marks.

- It is important to note that the right of application does not confer the right to protect the sign as a trademark. Until the trademark subject to an application that creates a right awaiting registration is actually registered, it will be subject to protection under the laws of unfair competition.

- Compensation claims can be made concerning situations that arise after the publication of the trademark application. The publication of the trademark application indicates the beginning of a two-month period during which it may be open to objections from third parties following the initial administrative examination. This stage is still part of the administrative process, as the trademark has not yet been registered. However, the rights that arise from the publication of the application will be evaluated within the scope of the rights of a registered trademark once the registration is published. In the event of a lawsuit, the court cannot decide on the validity of the claims before the publication of the registration.

- For these reasons, it is not recommended to use the trademark before it is registered. However, if a mark has been in use for a long time and is definitively distinct, its prior use means it cannot be classified under the recommendation against non-use stemming from the application status.

- The rights provided by the trademark take effect against third parties as of the publication date of the trademark registration. The publication of the trademark registration is understood to signify the end of administrative processes and the decision to document the registration.

- After the trademark is registered, the owner can initiate any legal or criminal claims. Trademark registration is a document that gives the owner the sole right to use the trademark and, as such, grants economic rights related to its use.

- Similarly, the trademark certificate gives the owner the right to prevent others from using identical or confusingly similar trademarks. This right to prevention encompasses filing lawsuits for infringement, seeking injunctions against infringement, compensation claims, and the right to file criminal cases aimed at seizing products, molds, and components used in the production of infringing goods.

In trademark registration, the principle that "the first applicant receives the certificate" applies; however, trademark legislation in Turkey also includes provisions that protect the first actual user of the trademark, rather than solely the one who registers it first.

In this case, a person who can demonstrate that they were the first to actually use the trademark and can provide evidence of this usage is regarded as the true rights holder of the trademark. The law favors the true owner of the trademark rights by recognizing the person who is the first actual user as the rightful holder.

As a result, even if a third party registers the trademark, the individual who was the first to use it can bring an action for invalidity against the later registrant by proving their actual use. This gives them a priority right based on their prior use, enabling them to seek cancellation of the registration and achieve registration of the trademark in their own name.
