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, product or service.For example,

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.For example

In the US, the registered trademark symbol was originally introduced in the Lanham Act.
