Trademark is any unique expression related to a product or service that distinguishes it from others. This expression could be a word, slogan, photograph, logo, graphic, colour combination, sound or even smell; however, most businesses are only looking for a brand name registration or logo registration. Owners of trademarks have exclusive rights to their use under the categories they are registered in (there are a total of 45 categories, called classes).
Trademark registration enables owners to easily establish their right to the trademark in court and earn royalties. It also deters piracy and prevents similar company names from being registered by other businesses. You can conduct a trademark search, to check if your brand name clashes with existing trademarks. In India, you could get a ™ within three days, but it takes up to two years for it to be registered so that you can use the ® symbol.
Trademarks in India are registered by the Controller General of Patents Designs and Trademarks, Ministry of Commerce and Industry, Government of India. Trademarks are registered under the Trademark Act, 1999 and provide the trademark owner with a right to sue for damages when infringements of trademarks occur. Once a trademark is registered, R symbol can be used and the registration will be valid for 10 years. Registered trademarks nearing expiry can be easily renewed by filing a trademark renewal application for a period of another 10 years.
