OPINION
“Anticipation is established only when a single prior art reference discloses,
expressly or under principles of inherency, each and every element of a claimed

In response to the section 102 rejection over Drewry, appellants submit that the
reference fails to teach the claimed steps of transmitting a bitmap from the host
computer to the channel control processor, the bitmap comprising a plurality of bits, and

from the mass data storage device corresponding to enabled bits of the bitmap.
According to appellants, the bitmap described by Drewry refers to an actual data object
being requested by the client for display. The bitmap is thus not used to indicate data to
be pre-staged. (Brief at 4.)
According to the rejection, Drewry refers to a “bitmap” in column 7. However, the
claimed bitmap to be transmitted is deemed to correspond to a “storable,” described in
column 4 of the reference. Bitmaps are defined as data structures used to describe
data bits which are stored in memory, which is exactly what Drewry’s “storable” does,
according to the examiner. (Answer at 4.)
Drewry is directed to a client/server system suited for an interactive television
environment. The “clients” may comprise set top boxes that have relatively small
amounts of local memory. Col. 1, l. 1 - col. 2, l. 2. Drewry teaches methods which allow
