I have this doubt after read about the registered (trademarked or copyrighted, I don't know exactly) SarcMark infamous symbol for mark sarcasm in texts.
Anyone can register a symbol or the idea of the shape of a symbol (grapheme) or only can be registered a concrete typography of it (glyph in a concrete typeface)?
This symbol (grapheme) is registered as a symbol in a font (typeface), but could I create my own font which contains this same symbol (grapheme) in a different glyph form (although both forms were very similar)?
If I can, what are the real scope and aim of the registration of that symbol (glyph)? Ethical and Aesthetically, it is fair to register a symbol which is pretended to be used in communication and language, which is a fundamental part of the patrimony of the entire Mankind? What if Greeks, in order to pay his debts, decide to register their alphabet, language and word roots? I think it's absolutly ridiculous!
