The creation of folders in iOS, for example, is an original idea that requires the user to simply take an app icon and drop it over another, creating a folder in the process. This method was later adopted by Google in Android 4 ICS. Icon rearrangement, on the other hand, requires the user to hold their finger over an app icon for a moment, which automatically activates the rearrangement mode, causing all the apps on the home screen to start "jiggling."
It's uncertain whether this patent will help Apple defend its ideas, but still, it's good to know that the patent is held by its rightful owner. Here's the abstract from the patent application:
