Any name that is designed to distinguish the goods and services of one legal or natural person from the goods and services of another legal or natural person is called a trademark which consists of names, symbols, figures or numbers and can be published and reproduced through printed materials. According to Industrial Property Law No. 6769, trademarks that have the same or differentiating features with a trademark that has been registered in a certain class cannot be registered in the same class. Using a registered trademark without changing its main elements or distinctive characteristics may be sued against those who are considered to use the trademark. The trademark owner may pledge the registered trademark, show it as a guarantee or transfer it to another.
