Earlier quoted context omitted.
It doesn't matter if they're original. No company should have exclusive rights to rounded corners.
It's not just "rounded corners." The patent addresses a very specific design, with rounded corners, a border, etc. It is basically only infringed if you try to make your product look like an iPhone, in order to free-ride on the iPhone brand, which is exactly what Samsung did.
Anyway, shouldn't this be copyright law and not patent law?
