The service mark symbol, designated by ℠ (the letters SM written in superscript style), is a symbol commonly used in the United States to provide notice that the preceding mark is a service mark. This symbol has no legal force, and is typically used for service marks not yet registered with the U.S. Patent and Trademark Office; registered service marks are instead marked with the same symbol used for registered trademarks, the registered trademark symbol ®. The proper manner to display the symbol is immediately following the mark in superscript style.
The character is mapped in Unicode under position U+2120[1] or ℠ in HTML[2]. Unlike the similar trademark symbol, there is no simple built-in way to type the service mark symbol on Microsoft Windows or Macintosh systems.
