Definition TM/ Trademark- 

  1. Trade Mark. Intellectual property comprising a word, phrase, logo, or other graphic symbol, sounds, or colors used by a manufacturer or seller to distinguish its products.


  2. A trademark, trade mark, or trade-mark is a recognizable sign, design, or expression which identifies products or services of a particular source from those of others, although trademarks used to identify services are usually called service marks. The trademark owner can be an individual, business organization, or any legal entity. A trademark may be located on a package, a label, a voucher, or on the product itself. For the sake of corporate identity, trademarks are often displayed on company buildings. (Reference - Wikipedia)

  3. The essential function of a trademark is to exclusively identify the commercial source or origin of products or services, so a trademark, properly called, indicates source or serves as a badge of origin. In other words, trademarks serve to identify a particular business as the source of goods or services. The use of a trademark in this way is known as trademark use. Certain exclusive rights attach to a registered mark.
