Okay, and do you think having a glossy effect on your icons is important in any way? Is that the magical secret sauce key to selling millions of phones? And, even if it was, do you think it's a significant enough "innovation" to warrant any kind of protection? While we're at it, do you think that if I comb through every Apple product, application, and website, there isn't at least
one minor element that a designer lifted from some pre-existing design found elsewhere? Be realistic.
Finally, a "clone" is different than minor design similarities. I specifically mentioned this in my post. Did Samsung copy every detail of the iPhone to make an indistinguishable product? No. They made an easily-distinguishable competitive product. I don't see how you can bring Chinese app clones into this discussion. Samsung's goal was never to confuse consumers.
Btw, Microsoft didn't come up with their own UI design from scratch. They were heavily influenced by Apple's original OS designs. For the past two decades, Jobs repeatedly accused Windows of being a copy. Look it up.
