A trademark is a protected sign of a legal or physical entity, but it is also a subjective right in the field of industrial and intellectual property, which takes as its subject of protection a sign with which the trademark holder marks his goods or services in commercial traffic, making them different from the same or similar goods or services of another participant in economic traffic. It is displayed in any suitable form using generally available technologies, provided that such display enables registration within the Intellectual Property Office in a clear, precise, independent, easily accessible, understandable, permanent, and objective manner. Regarding their form, they are divided into conventional and non-conventional, i.e., non-traditional trademarks, which represent new forms of trademarks and which, due to their characteristics, are often very difficult to register. They are focused on the sensory perception of the consumer, by which, through smell, taste, touch, and hearing, they try to win them over to choose their product. Due to the constant efforts of both European and, secondarily, Croatian law in providing trademark protection, numerous legal acts have been passed that try to prevent the theft and abuse of legally registered trademarks.
