A trademark is the right protecting a sign capable of distinguishing the products or services of one undertaking from the same or similar products/services of other undertakings. The nature of the products/services to which a trademark is to be applied shall not constitute an obstacle to registration of the trademark.

A sign that is capable of distinguishing identical or similar products/services, and that may be represented graphically may be protected by a trademark. A sign may consist of: words, including personal names, drawings, letters, numerals, images, the shape of a product or its packaging, colours, tri-dimensional forms or the combination of such elements.

A trademark as an identity sign has four main functions: distinguishing products/services, their source, quality, and market promotion. A trademark is granted by a responsible authority of a state with the payment of fees, and it lasts for a certain period of time in a certain territory.
