I think maybe you're taking the comment Fritz quoted too much to heart, and I have to say I really don't buy that argument that any licences that weren't given to the Extreme Ghostbusters production was down to Columbia/DiC not being “generous enough”, I find it much more believable that either the XGB production team didn't see the need to get all the designs, or the XGB legal team being sloppy to be much more likely.
I'm not passing judgement on the I.P. profession as a whole, but as we all know with all walks of life there are those who do their job well and then there are those who do the bare minimum.
If the XGB production team didn't see the need to get all the designs, it is unlikely that they would have created art for a Venkman statue only to blur its face out; they would have just used the XGB version of Venkman or made the statue a featureless manikin.
And it's true that every profession has good people and bad, but I find it hard to believe that the intellectual property lawyers behind the XGB production team dropped the ball. As I've seen these scenarios play out time and time again, the most probable scenario is that an agreement wasn't reached because Columbia/DiC wanted more money than the XGB team was willing/able to part with, hence Columbia/DiC not being “generous enough.”
