STIX Trademark?



I probably shouldn’t ask questions I might not like the answer to - but I was asked a question about the STIX trademark (in a different context) and OCA came to mind because OCA uses the four letters “stix” quite a lot. E.g. the OASIS announcement for OCA contains “STIX” 14 times (and none with a “TM”). The CTI TC mostly (always?) uses 4 capital letters and puts the TM symbol on it. Since they don’t have a footnote saying it is someone else’s trademark, does that mean it is an OASIS trademark? I thought DHS or MITRE “owned” the STIX trademark. Can we refer to the OASIS “STIX” specification without using the TM? If we do use STIXTM, do we need a footnote saying “STIXTM is a Trademark of the MITRE corporation”? If we use it in other contexts (eg as part of another name like stix shifter), can we use lower case and not bother with the TM? Can/should I put STIXTM on a CC-BY-4 webpage (eg for Architecture Working Group)?

I’m hoping there is some blanket agreement that allows us to use STIX and that we don’t endanger anything if we aren’t perfect in always annotating it with a TM (or better yet, that we don’t have to use TM all).
