That is not correct. I am aware of no country that uses the mark "TM" to signify registered trademarks. The circle R mark is used in the US after granted by the USPTO.
The rest of us are not legally allowed to write newLISP. Lutz has to allow it explicitly, but it goes against basic purpose of trade mark. This or other way, even if we are allowed to use newLISP, item in Wikipedia or any "open" text that follows common writing rules shouldn't be written as a trade mark. Even if Lutz (who has the right to write newLISP) did it, editors should not allow it.
This is mostly correct for a REGISTERED mark. But because newLISP is NOT registered, there is a lot of legal gray area about others using the same mark. In any case, there is no legal requirement to ask the USER (note I did not say OWNER) of the mark for permission to display the mark on other products or services. And similarly, an unregistered mark can be used by others in citations, etc., without appending "TM".
If other people write newLISP, and Lutz doesn't warn us against it, and he is too polite to do that, we harm him. His chance for retribution in the case of infringement are decreased, because he didn't "defended" his trade mark.
This only applies to registered marks. But in any case, the matter of due diligence is involved, and that can also be a tricky area, especially when various countries have different rulings for what constitutes due diligence.
Lutz can decide to NAME (not trade mark) Newlisp to be newLISP.
That is exaclty what using "TM" allows
- but it is questionable idea, first, it is not obvious that one can introduce his own spelling rules as a name (not trade mark) of the product in all countries. second, if that is done newLISP is not trade mark any more and Lutz has to invent new one.
As you'll see below, there ARE variations allowed in trademarks that comprise only (specified) alphanumerics.
It is like UNIX and Unix. Owner of the trade mark should write UNIX, the rest of us Unix.
Assuming this is a US trade mark, it is wrong in two ways: upper/lower case is not important so both examples are the same in the eyes of the USPTO; it needs to be appended with the circle R symbol.
Actually, according to the mark "newLISP
TM", this is not a registered trademark, so legal issues regarding others using it are not so clear cut as a trademark registered with a body such as the US Patent and Trademark Office (USPTO, which allows using the circle R symbol after they notifiy you that your mark has been officially allowed). By appending "
TM" to an unregistered mark, you make a public declaration that your product or service is to be recognized by that mark. That does not mean you "own" the mark. To "own" it, it must be registered with a recognized legal authority, and not all countries agree to be bound by the terms of other countries or by multi-national associations.
But even for a registered trademark, at least with the USPTO, that uses only alphnumeric characters, the size, font, weight, oreintation, etc. are NOT restricted to only the form in the trade mark application. ALthough not spelled out in the USPTO documentation , I suspect that the only requirement is that the characters be presented in the order given on the application. So "newLISP" and "newlisp" and "
newLISP" are all allowed variants, but things like "PSILwen" and other simialr variants of the order are not covered by that application.
And the issue of formating raised in the Wikipedia entry is blatantly wrong in US trade mark law. There are two classfications of marks: those of only (sanctioned) alphanumerics; and those of "graphical" marks, including size, shape, color, orientation, etc. And you pay more for the application for the latter type than the former type.
