Trademark protection in India requires owners to continuously use their trademarks by maximising their promotion and advertisement through all platforms. 

A trademark must be a mark that includes a device, heading, brand, label, ticket, signature, word, letter, name, numeral, packaging, or combination of colors or any combination of the above attributes. It should be easy to speak and spell and easy to remember.

The TM symbol is used when an application for a trademark is made with the trademark registry. The TM symbol is thus used to indicate the fact that a trademark application exists with respect to the trademark and serves as a warning for infringers and counter-fitters. The TM symbol can be used once you have filed the application.

The symbol ® is used when the applicant actually got the trademark registration. It shows the status of a trademark. Once the trademark is registered you can use the ® symbol next to your trademark.

Symbol © signifies that a particular work is protected under the relevant Copyright Act. Unlike trademarks, the moment your work comes into existence, it gets copyright protection by default, in absence of copyright registration. Thus, you can simply put © at the end corner or the beginning of your literary or any artistic piece of work or you can flash a declaration about your copyright on that particular work along with the name of the copyright holder and the year in which it was first published.
