It is my impression (IANAL) that such usages are not necessary, nor are they standard in English-language writing style, when the usage is of a journalistic or encyclopedic nature rather than as part of marketing materials. After all, Wikipedia has many articles, like [[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.
