Yes, it is possible to register a scent (olfactory trademark) and it is also possible to register a sound (sound trademark), since the current Law provides that these types of trademarks are registrable. In an olfactory mark the smell cannot derive from the nature of the product itself, for example, the case of perfumes.
Nor can the olfactory trademark have the scent of the product itself, for instance, someone who sells chewing gum cannot register an olfactory trademark that smells like chewing gum. An example of a national scent brand is the ecological paint with bamboo forest scent, which meets the above mentioned requirements.
Sound marks consist of musical sounds, pre-existing or created by devices, and for their effective registration it is required that the listener is able to associate the product with its origin or differentiate it from other similar products in the market. An example of this mark is the melody generated by 5 tinkling tones and from the third one onwards, Coca-Cola is heard being poured into a glass.
