If they weren't allowed stupid patents no one would be infringing. Really, status bars and menus? Multitasking? Gmail like emails? Lists? Seriously?
Besides, apple copies too, no? They took the notification bar. Did they not draw inspiration from android? you think there wasn't an internal document at Apple showing exactly how the notifications on Android work?
Problem is Google has not been granted a patent on notification bars of yet. You can't use that as an example in court when no one has a patent on it currently. And not to mention this is Samsung vs. Apple not Google vs. Apple. It's about what in TouchWiz, not stock Android.
