> Samsung deliberately and shamelessly copied Apple's products
Maybe I'm missing something here, but if Samsung really copied from Apple, I'd have expected a lawsuit about copyright infringement, not about patents.

In some cases Samsung's lawyers's couldn't tell Samsung devices apart from Apple's devices[1].
When Samsung copies how Apple does something (that they've patented), it's a Patent infringement - which has the potential for more damages, so is generally preferred.
Copyright would apply if they had stolen or copied source code or original artwork and were using it verbatim.
