Well, most icons and symbols and so on are pretty much all self-made - by Grandpa, misalo and co. The only things re-used are the blast/burst/melee/ranged icons from the MM. These are quickly replaced by something similar that conveys the same idea.You missed copyright images and trademarked logo's ...or other trademarked things.
And once the DDI -> powercards converter works, we really don't have to use anything directly from WotC.
