Trademarks, Registered Trademarks

For trademarked and registered trademarked items, include the appropriate symbol with the first or most prominent use of the item. Subsequent uses within the same page or chapter don't need the symbol.

Use a trademarked name only as an adjective, not as a noun or a verb (for example, write your BlackBerry smartphone, not your BlackBerry), and do not alter a trademark (for example, do not use BlackBerries). For Microsoft trademarks, see the Microsoft Trademarks Web page.
