Marks that can be registered as EU trademarks include words, graphics, three-dimensional signs, colors, and sounds, but they must be distinctive (can be distinguished from other products and services), can be expressed clearly and objectively, and It must not conflict with prior rights. Marks that are purely descriptive, that is, only describe the characteristics of a product or service, cannot be registered as an EU trademark.

EU trademarks are divided into individual marks (individual mark), collective marks (collective mark) and certification marks (certification mark). EU trademarks operate in parallel with domestic trademarks in EU countries and do not conflict with each other.
