Appeal 2007-2131
Application 10/401,331
decompresses files, we conclude that the scope of the claimed “archiving
means” encompasses equivalent mechanisms that also perform the function
of archiving using compression and decompression techniques, such as those
mechanisms taught by Ishii and Culbert, as pointed out by the Examiner in
the Answer (see Answer 4).
We further disagree with Appellants contention that neither Ishii nor
Culbert teaches an “identification means for identifying one or more content
files in content storage that are candidates for archiving based on access
information,” as claimed (see Br. 12, see also claim 16). In contrast, we find
Ishii clearly teaches compressing files with low access frequency and
decompressing files with high access frequency, as follows:
It is not until the available capacity becomes lower than the
threshold value that files are compressed. For such
compression, a search for files to be compressed is conducted
based on the file control information of the file attribute
controller 132 (Step 220). From the files other than those for
which compression is prohibited by the user, non-compression
files with low access frequency are picked up. If there is no file
to be compressed, the system returns to Step 210. In Step 221,
it is judged whether there is any file to be compressed. The
term "File to be compressed" means the files subject to
compression until the available file capacity exceeds the
predetermined threshold value [emphasis added].

alleged corresponding structure in specification for claimed “means for
converting” was a frame grabber, computer video processor, and software
routines (not described) for performing the conversion).
