I remember reading a document that stated a few "Words" to use when determining Obviousness. I querried the words in thesaurus and of course up came many more similar words but they basically ment the same thing. Can't remember for sure was a while back, but the words made me think that the 336 and 148 were not obvioous because of what they yielded. That the three main patents were strong because while the industry ws going left these went right andresulted in something unique. Someone schooled in the art would have still been going left when what Moore and Fish did was way out of the box for the time.
