The trademark symbol (), in Unicode U+2122 trade mark sign (HTML ™ · ™), \texttrademark in LaTeX,[1] [2] is a symbol to indicate that the preceding mark is a trademark. It is usually used for unregistered trademarks, as opposed to the registered trademark symbol (®) which is reserved for registered trademarks,[3] on Windows it may be entered by holding the Alt while typing the numbers 0 1 5 3 on the numeric keypad or by holding the Alt Gr and typing T.

Use of the symbol[edit]

Use of the symbol indicates an assertion that a word, image, or other sign is a trademark; it does not indicate registration. Registered trademarks are indicated using the registered trademark symbol (®), and in some jurisdictions it is unlawful or illegal to use the ® symbol with a mark which has not been registered.[4]

Trademarks versus service marks[edit]

There is a specific symbol () to indicate the assertion of a service mark (a trademark for the provision of services), the service mark symbol is less commonly used than the trademark symbol, especially outside the United States.
