Re: From TFP..
No, you need to look at the independent claims (the claims that don't reference a previous claim). If a device does everything described in each independent claims, then the patent applies.
IMO this patent is a bit more specific than many people would suppose. Nothing supplants the independent claims, but to help with some understanding of what they mean, on my reading they relate to having a heuristic (read algorithm) to detect, based on single or multiple touches, if scrolling should be constrained to being vertical or horizontal or (typically if the angle of movement is beyond a certain threshold, e.g. at 45 degrees instead of 5 degrees), and a heuristic (read algorithm) to determine if the the scrolling should "snap out" of being constrained to vertical and/or horizontal mode.
It's a nice feature for certain styles of interface (like the rubber-band effect on reaching the end of a scrolling table is nice), but this combination of constrained left-right, up-down scrolling combined with freeform scrolling if you really want it, is only useful in a relatively small subset of interfaces. Additionally, I believe the interface would need to implement all those things, plus allow the selection of sub-screens before it runs foul of this patent.
An example of why this is a limited patent is given by Apple themselves. Go to the App Store, you can scroll content up and down, scroll screen shots left and right and select to view a screenshot full screen. However you can't try to move a screenshot at 45 degrees up the screen and find it will break out into the freeform scrolling mode. So the app page alone does not clearly "contravene" this patent.
A more vexing question is if the patent applies if the API's implement functions which specifically support presenting to an app occurrences of 1 dimensional vertical scrolling, 1 dimensional horizontal scrolling and 2 dimensional freeform touch tracking/scrolling and item selection.
No warranty is made as to the validity of this interpretation !
