Registered trademark symbol

  (Redirected from Registered trademark)

The registered trademark symbol, ®, is a typographic symbol that provides notice that the preceding word or symbol is a trademark or service mark that has been registered with a national trademark office. A trademark is a symbol, word, or words legally registered or established by use as representing a company or product.[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.[3]

Unregistered trademarks can instead be 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; the symbol is commonly in superscript style, but that is not legally required. In many jurisdictions, only registered trademarks confer easily-defended legal rights.[4]

In the US, the registered trademark symbol was originally introduced in the Trademark Act of 1946.[5]

Because the ® symbol is not commonly available on typewriters (or ASCII), it was common to approximate it with the characters (R) (or (r)).[a][b] 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..[7] in the US.[2]

Computer usageEdit

The registered trademark character was added to several extended ASCII character sets, including ISO-8859-1 from which it was inherited by Unicode as U+00AE ® REGISTERED SIGN.[8][9] This is a different character from U+24C7 CIRCLED LATIN CAPITAL LETTER R as many fonts draw the registered trademark symbol smaller and possibly superscripted.
