Re: Physically based kinetic scrolling

[Lieven van der Heide <lievenvanderheide gmail com>]

After a quick look at those patents, they seem to be just about allowing the user to scroll past the edge, and moving the document back when the touch is released, not about the actual curve that should be used (and of course, I assume it can't be possible to patent the laws of physics anyway). I think that if this new implementation violates it, then the previous implementation would violate it just as much. 

But then again, it seems the patent has been ruled invalid anyway, because of prior art:

But I'm no lawyer either, so maybe someone else can look at this?

Regards,

Lieven.
