A trademark is a unique symbol or word(s) used to represent a business or its products.A trademark is a type of intellectual property consisting of a recognizable sign, design, or expression which identifies products or services and legally differentiates it from all other products of its kind. A trademark exclusively identifies a product as belonging to a specific company and recognizes the company's ownership of the brand. Unlike patents and copyrights, trademarks do not expire after a set term of years. The purpose behind trademarks is to allow companies and individuals to indicate the source of their goods or services and to distinguish them from others in the industry.A trademark not only gives the trademark owner the exclusive right to use the mark but also allows the owner to prevent others from using a similar mark that can be confusing for the general public. A trademark cannot, however, prevent another person or company from making or selling the same goods or service under a clearly different mark.
