Fun patent of the day

Alright, I suppose I can see the value in making the paging interface more word-processor
intuitive, as in "page" = one standard-sized paper piece.  Which is essentially
re-granularizing the idea of document paging to be paper-page-compliant, as opposed to
more/less where the paging distance is based on display length (arguably more sensible for the
form).

But *patenting* such an obvious notion -- especially in the growing legal environment of
invalidity for "doing the above method in software on a computer" -- seems ridiculous!  You're
going to license the idea of interpreting paging commands according to the actual pages of a
document?  Amazon.com is calling, they want their lawsuit back.

Now, who do we know that might have done this before 2005?  Adobe?  Some other PDF-viewer
(like one of ours, where a documented commit might exist)?

Abstracting out the generic elements of a) software on storage medium, b) executed in a
computing environment, and the fact that c) you can't patent math (the equations by which they
calculate position and distance), the specific elements of the patent seem to be a
properly-constructed program/set of programs that displays a document, calculates position and
distance in pixels based on zoom level (which are also a detail that might be generic and
abstractable), and responds to PGUP/PGDN events by moving the current view to the same
relative location on the next or previous print-page representation.  For bonus points, they
cover the idea of having variable page sizes within a document, and accounting for
program-generated white-space in the display view.  

IOW, it seems they're patenting any piece of software that does print-page-size calculations
on generic hardware using the normal display unit of measure, can be configured to respond to
PGUP/PGDN with print-page granularity on decrement/increment, and has some of the bugs of GUI
implementation worked out.
