display on desktop computers with color monitors having at least 640x480 resolution.
Most PDAs and cell-phones, however, feature smaller displays. More specifically, the
difference in displays can lead to ratios of designed vs. available display area from 4-to-
1 to 100-to-1. The appellants opine that such ratios make direct presentation of most
Web documents on PDAs and cellular telephones "aesthetically unpleasant, un-
navigable, and in the worst case, completely undecipherable." (Spec. at 1.)
Accordingly, the appellants' invention "re-authors" a Web document for display
on a PDA or cell-phone. More specifically, the document and re-authoring parameters,
such as the size of a display and a default font, are input. The document is converted
into pages, where each page is fully displayable with almost no scrolling on the display
of the PDA or cell-phone. At each stage of re-authoring, transformations are applied to
the original document or to a "re-authored" page. The re-authored page is the best
page resulting from the previous re-authoring stage. At each stage, the best page is
determined based on the re-authoring parameters and the content of the document
being re-authored. (Id. at 53.)
