Registered trademark symbol
The registered trademark symbol, designated by ® (the circled capital letter "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.[1][2] In some countries it is against the law to use the registered trademark symbol for a mark that is not officially registered in any country.[1]
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 character has a standardized representation in most computer systems. It is mapped in Unicode as U+00AE ® registered sign (HTML: ® ®).[3] 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 not commonly been available 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.[4] 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.",[5] in the U.S.,[2] and the letters "RTM" in the UK.[1]
