(answer at page 8), the examiner asserts that "Figure 3 of Ellis
illustrates ... the same comparison technique, wherein the input
frames are compared [in element] 420 based on information (e.g.
the corresponding error count) generated by comparing each of the
previous frames (see col. 11, lines 28-46 and feedback loops
404-406-408-420 and 404-414-422-404 in Fig. 3)." We are
persuaded by the examiner's position. Ellis discloses a
technique where the input frames are compared based on the
information generated by comparing each of the previous frames as
pointed out by the examiner. Therefore, we sustain the
obviousness rejection of claims 27 and 55 over Takahama and
Ellis.
IV. Claims 33 and 46
Appellants argue (brief at page 11) that "if a successful
comparison occurs, which includes the beginning or ending portion
of the memorized segment, at least one frame is added to the
beginning or ending portion, as appropriate. Neither of the
Ellis nor Takahama patents discloses this concept of adding one
or more frames to a stored information segment based on a
successful comparison which includes the terminal frame of a
stored segment." The examiner responds (answer at page 8) that
"Takahama et al disclose such concept that the memorized segment
