A Trademark generally refers to a “brand” or “logo”.
Trademark registration can also be obtained for a business name, distinctive catch phrases, taglines or captions.
Properly used and promoted, a Trademark may become the most valuable asset of a business. Trademarks such as Coca Cola, HP, Canon, Nike and Adidas serve as an indication of origin of the goods as well as an indication of quality.
Use of TM, SM and ® symbols
'TM' stands for Trademark and 'SM' stands for Service mark. The use of TM and SM symbols notifies the public that the company is claiming exclusive ownership of the trademark and can generally be used by one who has filed a trademark application.
The ® symbol, can be used only once the trademark is registered and the registration certificate is issued. Also, you may use the registration symbol only in connection with the goods and/or services in respect of which the trademark is registered.
