A word, phrase, logo,  symbol,  color,  sound  or  smell  used  by  a  business  to  identify  a  service  and distinguish  it from  those  of its  competitors.  In practice, the legal protections for trademarks and service marks are identical. A service mark is similar to a trademark  but is used  to refer to  services  rather  than goods. May be denoted by SM prior to registration (like TM); denoted by ® once.  A word,  phrase, slogan, design or symbol used to identify services and distinguish them  from the  services  provided  by  others is known as a service mark. Procedure for service mark is same as of trademark.
