I'm curious.... if somebody opened up a BBQ stand called "Supergrill" and had a picture of an offset with a red cape attached to it, what the opinion would be?
Although I'm not one for lawyers picking on random helpless entrepreneurs the question remains, are they really playing off of Godzilla as a known and recognizable icon to enhance their marketing?
The person who came up with Grillzilla at their naming party surely did not put those random words together. Even the description of said events points to the fact that they are referencing, even if its in the back of their heads, Godzilla, when making the comparison.
Another question is: When does something so iconic move from a copyrightable entity in to main stream culture that anyone could use, and with what limits?
