They just registered for "CORE-ONLINE" and "COREONLINE".

I was hoping for a possible Online Mech/Front Mission game (e.g. Armored Core Online), but it appears that "Core Online" is just a gaming service portal.

IC 041. US 100 101 107. G & S: Entertainment services, namely, the provision of online computer game services; online computer game services provided by means of an internet portal; information and advisory services relating thereto

This new registration is actually related to an older September filing called CORE:

They purchased the "CORE" trademark from another company a really long time ago too:

They don't appear to own most of the "CoreOnline" and "Core-Online" domains, so I don't think they have any serious or immediate use for this new trademark.
