How to internationally protect your trade mark through the Madrid system?

A trade mark is a sign that is capable of distinguishing the goods or services of one undertaking from those of others. In general, it is possible to distinguish several trade mark categories: word marks consist exclusively of words, letters, numerals and other standard typographic characters; figurative marks consist exclusively of figurative elements; figurative marks containing word elements are signs with a combination of verbal and figurative elements; shape marks consist of a three-dimensional shape; shape marks containing word elements are shape marks containing verbal elements; position marks protect the specific way in which the mark is placed on or affixed to the product; pattern marks are signs where a set of elements are regularly repeated.
