curious about the use of (R) and TM symbols


Hi everybody,

I am curious, why if "SPDX" is a registered trademark in the US (I just
checked--not in canada, by the way) then there is the requirement to
postfix it with "TM" and not with (R) as is the case with the full name:
"Software Package Data Exchange (R)"
