Trademark Registration Notices In The USA
People like to pour a liberal sprinkling of the symbol ® onto all advertising and packaging, whether or not there is a legal basis for doing so.
In the United States, a registration symbol properly is used only to give notice that a trademark has been federally registered.
Registration notices need not pop up every place the registered mark appears. It is enough to use a notice once with the first or most prominent use of the mark, and it is desirable to use a notice in advertising as well as on packaging.
The proper form of registration notice is ® placed in immediate conjunction with the registered mark. Alternative forms of registration notice, which may appear as a footnote with an asterisk placed next to the registered mark, are "Registered in the U.S. Patent and Trademark Office," "Registered in U.S. Patent Office," "Reg. U.S. Pat & Tm. Off." or "Reg. U.S. Pat. Off."
