This judgement says nothing about innovation. Note to whiners: copying isn't innovation. Apple innovate (and have exceptional design taste), that is why they are successful. Samsung just produce thinly disguised, poorly made knock-offs. Samsung have history, before the iPhone Samsung made Blackberry knock-offs, its what they do.
The important aspect here is that Apple went after the most obvious plagiarist (and softest target) first. Now there is a precedent, Google were the most blatant IP thieves and I have no doubt (nor do Google) that Apple are just warming up for the big game.
Obviously, you didn't look at all the designs Apple claims are copies. Unless you believe Apple invented the mobile phone, I don't think you can just claim that this isn't preventing innovation.
