A registered trademark contributes to the value of the goods and services and it increases the chances of marketability of the product and therefore it adds to the commercial value of the goods and services .
Trademark prevents others from using the trademark: Once a trademark is registered it cannot be used by any other person except the proprietor of such trademark . The user of such trademark has the legal right to sue and stop other from using his registered trademark and also has the right to recover profits, damages and costs which he has incurred due to trademark infringement.
It serves as a constructive notice : The registration of trademark serves as an indirect notice to the public that the trademark has been registered in India and therefore such registration can form a basis of registration in other countries as well .
