The trademark symbol () 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 trademarks registered with the appropriate government agency.[1]

Trademark symbol

In Unicode it is U+2122 TRADE MARK SIGN.[2] In HTML the code ™ or ™ can be added.[3] LaTeX uses \texttrademark. On Windows it may be entered by holding the Alt while typing the numbers 0 1 5 3 on the numeric keypad (it is at 0x99 or 153 in CP1252) or by pressing Alt Gr+T. On macOS, it may be entered by pressing ⌥ Opt+2 . On Linux and some other POSIX-compatible systems the trademark symbol may be entered by keys sequence Compose T M.

An equivalent marque de commerce symbol (U+1F16A 🅪 RAISED MC SIGN) is used in Quebec.


Use of the trademark 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 registered trademark symbol with a mark that has not been registered.[4]

The use of the trademark symbol can also have an ironic meaning unrelated to trademark law.

Trademarks versus service marksEdit

There is a specific symbol, the service mark 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.
