Appeal No. 1997-1230
Application 08/274,807
Also, in the description of the prior art in the
background section of Patent No. 5,805,379 at column 1, lines
41-45, it is noted that prior art cartridge disks
conventionally require the use of finely machined parts having
exceptionally close tolerances.
In light of the foregoing, the examiner should consider
whether it would be appropriate to enter a prior art new
rejection of one or more of the pending claims of the present
application based on the above noted teachings and other prior
art references pertaining to the construction of the hub of a
platter assembly for a magnetic storage disk of which the
examiner may be aware. In this regard, in that appellants in
this appeal have not specifically argued the claimed twist-
lock connection feature of the platter assembly top to the
platter assembly hub as a patentably distinguishing feature of
the appealed claims over the cited prior art notwithstanding
that the applied prior art may not adequately address this
feature, the examiner may wish to have appellants clarify the6
record as to the nature of the prior art platter assemblies
