intellectual property question

This was rejected for intellectual property.
Although I haven’t found the Iowa on any list, if it's protected I don’t want to waste anyone’s time resubmitting it.
However if the problem is just a trademark issue with the signage behind the blue tent it’s easily fixed. Does anybody know?
And yes (before somebody points it out) I would take care of that reflection in the lower right before resubmitting it if I did.
