The registered trademark symbol, Template:Char, 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, product or service.[1][2]
Unregistered trademarks can instead be marked with the trademark symbol, Template:Char, while unregistered service marks are marked with the service mark symbol, Template:Char. 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.[3]
In the US, the registered trademark symbol was originally introduced in the Trademark Act of 1946.[4]
Because the symbol is not commonly available on typewriters (or ASCII), it was common to approximate it with "Template:Tt"[5] or "Template:Tt".[a] It is also legal in the US to use the text "Registered, U.S. Patent and Trademark Office" or "Reg U.S. Pat & TM Off."[2][6]
