2.1 Registered signs
Article 140 of Law 9947 defines which signs may be registered as a trademark: Every sign or combination of signs that can be represented graphically and that serve to distinguish goods or services of a person from those of another person, can be registered as a trademark. Such signs may be words, letters, numbers, abbreviations, figurative signs, drawings, two- or three-dimensional forms, forms of goods and/or their packaging, colours shades and their combination of colours per se. This criterion that marks have to be represented graphically is particularly important for the question whether special types of marks such as sound and light signals can be registered.
