The trademark symbol (™; Unicode U+2122 ™ TRADE MARK SIGN (HTML
\texttrademark in LaTeX) 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.
On Windows it may be entered by holding the Alt while typing the numbers 0 1 5 3 on the numeric keypad or by pressing Alt Gr+T. On macOS, it may be entered by pressing ⌥ Opt+2 .
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.
Trademarks versus service marks
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.
