Ultimately, I'd agree that Apple are being far too aggressive in this, but IMO the similarities go further than you describe. The Galaxy Ace [1] (I assume the court cases are at least in part about the Ace?) looks very similar to the iPhone and is practically the same size. My Ace is stored in an iPhone case, and it fits almost perfectly.
It also ships with a "Samsung Keypad" as the default input device. As far as I can tell, all this does is make the keyboard look more like the one on the iPhone. Compare the Samsung keyboard [2] with the iPhone keyboard [3].
As I said earlier, I personally think that Apple are pursuing this further than I would like, but in some cases it seems (to me at least) that the similarities are more than incidental.
