What kind of trademarks can be registered?
Trademarks may be a single or a combination of words, letters, numerals, drawings, symbols, three- dimensional signs such as the shape and packaging of goods, audible signs such as music or vocal sounds, fragrances, or colors if those items are used as distinguishing features for goods or services. In addition to trademarks associated with a commercial source of goods or services, several other categories of marks exist. Collective marks are owned by an association whose members use them to identify themselves with a level of quality and other requirements set by the association. Examples of such associations would be those representing accountants, engineers, or architects.
