Trademark is a word, phrase, symbol or design or a combination of those that identify and distinguish the source of goods of one party from those of others. So your trademark is studiously crafted personality of your product or services or your company or Institution. A trademark is a “brand” or “logo” that you can use to distinguish your product from those of your competitors. Through trademark registration or you can say logo registration/brand registration, you can protect your brand or logo by restricting other people from using the same.
Owners of trademarks have exclusive rights to use trademark under the categories they are registered in (there is a total of 45 categories, called classes). Only Trademarks that are registered under the Trademark Act, 1999 provides the trademark owner right to sue for damages when infringements of trademarks occur.
