Trademark symbol

The trademark symbol ™ is a symbol to indicate that the preceding mark is a trademark, specifically an unregistered trademark. It complements the registered trademark symbol ® which is reserved for trademarks registered with an appropriate government agency.

In Canada, an equivalent marque de commerce symbol, 🅪 (U+1F16A) is used in Quebec. Canada also has an Official mark symbol, $⟨Ⓜ⟩$, to indicate that a name or design used by Canadian public authorities is protected. Some German publications, especially dictionaries, also use a Warenzeichen grapheme, 🄮 (U+1F12E), which is informative and independent of the actual protection status of the name.

Use
Use of the trademark symbol indicates an assertion that a word, image, or other sign is a trademark; it does not indicate registration or impart enhanced protections. Registered trademarks are indicated using the registered trademark symbol, ®, and in many jurisdictions it is unlawful or illegal to use the registered trademark symbol with a mark that has not been registered.

The service mark symbol, ℠, is used 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 sign, especially outside the United States.
