Many of Apple's concepts such as icons stacks, parabolic zooming in panels and (most recently) widgets on media centers that they seem to feel are patentable are either unoriginal or just plain trivial.
The widgets on media center patent
The only thing in that patent filing we haven't implemented yet that I can see, though we have certainly already discussed it, is linking widgets to specific remote control buttons. Global shortcuts for widgets is already on our roadmap, though, and that's pretty much the same thing, just not specific to a t.v. remote. Really, it's a beyond trivial feature add.
addendum: so this leaves us in a really annoying situation of having to figure out how to work around this patent, unless Apple decides to be nice about it. That would be a nice change on their part, but I'm not sure I should hold my breath.
I've stayed away from the whole patent world long enough to forget exactly how one goes about alerting the USPTO about prior art ... and I wonder if they'd really even care.
Future society will look back upon us and cluck their tongue at how stupid we were for having let the patent system encroach upon things such as software on the one hand and become so baroque a system as to be generally lacking usefulness on the other. =/
