Years refining this overscroll effect?
I don't know why people build so much of hate for big corporates. Samsung is no different. If you see number of patents Samsung holds, you will be stunned. And most of them are something they never even implemented in their software remotely.
I could probably see many things in iOS/the iPhone worth patenting, but this is not one of them.
I'm not against Apple, I'm against ALL useless patents like this and probably many of Samsungs'.
