What are Trademarks?
Trademark is a sign – a logo, a name, a word, a symbol or a combination thereof -- used within economic activities by a producer or vendor to identify a particular product or service. In other words, it is a 'distinctive sign' that enables offerings of goods or services to be--more or less consistently--differentiated, and consequently, enables consumers to distinguish between different goods and recognise their preference. These attributes make trademark an extremely powerful economic device.  The essential function or role of a Trademark is creating distinctiveness thereby enabling differentiation between brands. To sum up, it can be said that a trademark is a legally- protected word or symbol that is used to identify a business entity.
The primary reasons for the existence and protection of trademarks thus can be identified as: (1) To protect the public, by way of giving them confidence that, in purchasing a product bearing a particular trademark which it favorably knows, it will get the product which it asks for and wants to get.
(2) To Protect the owner of a trademark who has spent energy, time, and money in presenting to the public the product in a particular form, thus his investment is accorded protection from its misappropriation by pirates and cheats who may try to reap benefit out of his hard work and investments.
