A trademark can be any sign capable of graphic representation, such as words, letters, symbols, drawings, or graphics, or any combination thereof. Furthermore, individual surnames and personal names, as well as the names of legal entities, may also be registered as trademarks.

In Spain, signs that cannot be represented graphically—such as, in principle, sounds, scents or fragrances, or colours in the abstract without a specific form—cannot be registered. This does not mean, however, that the aforementioned are exempt from other forms of legal protection.

Certainly, provided that they are not similar or identical to others already distinguishing the same or similar goods or services.
