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.[3]
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 of the United States.
Entering the symbol [edit]

- In the X Window System, it can be input by pressing Compose, then T and finally M.
- On GNOME systems, it can be input by pressing Ctrl + ⇧ Shift + U + 2 1 2 2.
