Well, I got the distinct impression (though it may be colored by hindsight and the journalists it was filtered through), that Oracle originally thought the patent portion of the case contained the real offenses, with the copyright arguments more limited (and restricted to just code copying, which I recall they were fairly vague with at first, implying many more instances of direct copying than there was).
It was only as the patents were knocked off one by one that the copyright portion of the suit became their major complaint and what they were pinning expectations and their hopes to.
