Every country has its own definition of a trademark but in general terms we may say a trademark is a sign (word, phrase, symbol or design, or a combination of words, phrases, symbols or designs, even odors!!) useful to identify a product or a service.
How many times, while driving on a freeway with your kids, your 3-year old pointing at distant golden arches says: Look daddy, McDonalds!! This is what a trademark really is: a sign that even a little boy can use to distinguish his favorite restaurant!!
