Question: 

What is a trade mark?

Answer: 

A trademark is a distinctive sign that can consists of words, symbols, a slogan, a logo, or a combination thereof that distinguishes trader's goods or services from a competitor's goods or services. A trademark has no limited term of existence as long as the trademark holder continues to use the mark to indicate the source of good and services and pays the renewal fees.

The registration of a trade mark gives the trade mark holder the exclusive right to use the trade mark in the territories where it has been registered. A trademark, trade name or other similar indication may be associated with the denomination for the purposes of marketing or selling, provided that  the denomination must be easily recognizable as such (on documents, packaging, …).
