By the way, what is the difference(s) between \textregistered and \circleR? The LaTeX symbol list does not explain this but there must be some subtle differences. I now know the differences between \ldots and \textellipsis so I assume that there are meaningful (to someone) differences among the other choices, too.
\textregistered is the more or less official _text_ character. \circledR can also be used in text and math mode and is a symbol from package amssymb. There is a tiny difference
\scalebox{20}{\circledR\textregistered}
