Appeal 2006-2594
Application 10/034,394
A. INVENTION
The invention at issue on appeal transforms markup language
documents for display on wireless communications devices. (Specification
1.) Wireless communications devices such as mobile telephones and
personal digital assistants ("PDAs") provide access Internet World Wide
Web sites and enterprise intranet servers. Data retrieved therefrom include
documents created in a markup language such as a HyperText Markup
Language ("HTML") or Extensible Markup Language ("XML"). (Id. 1-2.)
Markup language documents from Internet-type servers are generally
created and formatted for display on systems having large display areas, e.g.,
personal computers or workstations. Wireless communications devices, in
contrast, usually feature small display areas incapable of displaying markup
language documents in the form in which they were intended to be
displayed. Graphic images, tables, and forms are particularly problematic to
display on wireless communications device. (Id. 2.)
Accordingly, the Appellant's conversion controller scans part of a
markup language document for tags associated with graphical images. The
controller replaces each detected image with one of a set of placeholders,
each having a label corresponding to a button. Actuation of the button
initiates display of the replaced image. The controller reuses placeholders to
replace graphical image within other parts of the markup language source
when the other parts are displayed. (Id. 4.)
