[[Coca-Cola]], that are named after trademarks, but don't display the
symbols demanded by the lawyers.
As far as I recall, there is no legal requirement to use either
symbol. (r) and ™ are used by trademark holders to inform you that
they consider the terms trademarks. It is not commonplace to use
those symbols when you are NOT claiming trademark status on the terms
yourself.
