Marvel and DC claim they own "superhero"

Zed sez, "It seems Marvel and DC co-own a trademark on the word 'superhero.'"
GeekPunk is announcing that their flagship comic book title featuring superheroes patronizing their favorite bar & grill during their off-hours will now be entitled Hero Happy Hour beginning with the fifth issue of the ongoing series.

According to creator Dan Taylor, "The decision to change the title was brought upon by the fact that we received a letter from the trademark counsel to 'the two big comic book companies' claiming that they are the joint owners of the trademark 'SUPER HEROES' and variations thereof."
