Appeal No. 1998-2003
Application No. 08/440,246
Appellant admits in the specification (page 5) that PostScript
was developed as an improvement to bitmapping to reduce the volume of
data to communicate printing information to a laserprinter. As
Steiner suggests a need to reduce the amount of data required, it
would have been obvious in view of appellant's admissions to use
PostScript in Steiner's system.
Further, Adobe teaches (page 1) that PDF improves performance
over PostScript for interactive viewing. Steiner includes user entry
38 for interactive viewing, such as for requesting information about
a particular portion on the display (see column 10, lines 18-24),
and, as indicated above, desires the ability to sort for data easily.
Therefore, it would have been obvious to use PDF instead of
PostScript for further improvement in interactive viewing. In other
words, appellant's admissions together with the teachings in the
references provide the motivation to establish a prima facie case of
obviousness. The level of the skilled artisan should not be
underestimated. See In re Sovish, 769 F.2d 738, 743, 226 USPQ 771,
774 (Fed. Cir. 1985). Further, contrary to appellant's assertion
(Brief, page 6) that the arts of the references are unrelated,
appellant's admissions and Adobe address the same problems set forth
in Steiner and are, therefore, related thereto.
