I had always dismissed the absurd trademark claim without thinking about it (because of the obvious prior art in the term), but yeah, a shared trademark doesn’t make a lick of sense. The whole trademark claim falls apart for multiple reasons.
It’s almost as if they always knew the trademark claim was total bullshit that they couldn’t defend if it got to court, and were just using the threat of a legal fight with the two biggest comic/media companies to scare the rest of the industry into submission.
