The registered trademark symbol, designated by ® (the circled "R"), is a symbol used to provide notice that the preceding mark is a trademark or service mark that has been registered with a national trademark office. In some countries, including China, it is against the law to use the registered trademark symbol for a mark that is not officially registered in any country.

Trademarks not officially registered are instead marked with the trademark symbol ™, while unregistered service marks are marked with the service mark symbol ℠. The proper manner to display these symbols is immediately following the mark, and is commonly in superscript style but is not legally required.

Computer usage

The registered trademark symbol.

The registered trademark character has a standardized representation in most computer systems. It is mapped in Unicode as U+00AE ® registered sign (HTML: ® ®). The registered trademark symbol ® is distinct, in computer representation, from the similar character U+24C7 Ⓡ circled latin capital letter r (enclosed R)

Because the ® symbol has long been unavailable on typewriters and ASCII-based computer systems, it has been common to approximate this symbol with the characters (R) or (r); for example, the Python programming language Trademark Usage Policy advocates this usage. However, these forms do not have legal force.^{[citation needed]} Example of legal equivalents are the phrase "Registered, U.S. Patent and Trademark Office", which may be abbreviated to "Reg U.S. Pat & TM Off.", in the U.S., and the letters "RTM" in the UK.
