Which signs can be trademarked?

A trademark is typically a name, a word, a phrase, a logo, a symbol, a design, an image, or a combination of two or more of these elements. There is also a range of non-conventional trademarks comprising marks which do not fall into these standard categories, but can also be registered in some cases, such as those based on color, smell, sound, moving objects, etc...

As a matter of fact, any sign that meets the requirements of Availability and Distinctive Character can be registered, as long as they are capable of being represented, in a manner which enables the competent authorities and the public to determine the clear and precise subject matter of the protection afforded to its proprietor.
