This important issue has arisen since the last few centuries when countries have been interconnected as if the whole world were like a house or a village and there has been strong commercial development all over the world and national companies have come into existence which are unprecedented in human history. It so happened that the goods offered to human beings differed in their excellence, characteristics and even in rates. It became difficult for every man to distinguish between good, inferior, best quality and low quality. Choose a method that allows the customer to distinguish between different quality items.The best way to do this is to use trade names and trademarks. In the early twentieth century, trade names began to be used¹. This is why we often hear that "something sells in its own name". The significance of this can be gauged from the fact that if a non-alcoholic beverage named Pepsi is removed from it, consumers will be reluctant to buy it as a normal drink, because it is trusted.
