a trademark is a distinctive symbol made up of characters, figures, letters, numbers, three-dimensional symbols, sounds and colors, or the combination of the above elements, which is adopted by the producers and operators of commodities on the commodities they produce, manufacture, process, select or distribute or the services provided by service providers, and is used to distinguish the sources of commodities or services. It is a product of modern economy. In the commercial field, trademarks, including words, graphics, letters, numbers, three-dimensional signs and color combinations, as well as the combination of the above elements, can be applied for registration as trademarks. A trademark approved and registered by the state is a "registered trademark" and is protected by law. Trademarks protect trademark registrants by ensuring that they have the exclusive right to mark goods or services or to license others to use them for remuneration.

Trademarks are trademarks of goods, not where they are sold and changed indiscriminately!
