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 also use a Warenzeichen grapheme, ⟨🄮⟩ (U+1F12E).
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 some 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 symbol, especially outside the United States.
