What is a Trademark?
A trademark is any visible sign capable of distinguishing the goods.
It is any distinctive word, name, symbol, emblem, sign, or device, or any combination thereof, adopted and used by a manufacturer or merchant on his goods to identify and distinguish them from those manufactured, sold, or dealt by others. It is "intellectual property deserving protection by law," and "susceptible to registration if it is crafted fancifully or arbitrarily and is capable of identifying and distinguishing the goods of one manufacturer or seller from those of another."
