By copying Apple's designs. Do they mean the rectangle with rounded edges? Because if so..... Apple copied the design of my sandwich to make the iphone....!
I agree that Touchwiz looks like iOS. But.... I don't think that is what Apple are going after.
But Apple could use the argument that it was "inspired by nature." A lot of companies do that, from furniture to cars. But "inspired by another company inspired by nature" sounds a bit of a stretch. Not saying Apple used nature, but an example.
And I think Apple is going after stock Android, not custom UIs. Wasn't HTC in this lawsuit? If they were, it wasn't after Sense, was it? Because that's pretty unique. Too bad HTC might go down.
Poor Motorola ate shit after the buyout/merger with Google. I see nothing on their front. Google really did just whore them out for patents.
