Are these features patented in any way or unique to Android?
No...
Since these Android devices would NOT exist in their current form had the iPhone not been released I think Apple has a much better claim to being ripped off.
That's the funny thing, the patents Apple are suing for aren't innovations, they are vague and they aren't exactly protecting any iOS experiences.
What exactly has Android ripped from iOS? They are pretty remarkably different in terms of UI and UI philosophy. On one hand Android's UI is there to improve your experience and allow you to customize the experience.. on the other hand iOS is basically just there to jump from app to app.
