Appeal No. 2002-1632
Application No. 08/941,785
Appellant further points to Figure 5 of Fujii and asserts that
actually an interpolation circuit is used for error correction
(id.). Further Referring to figures 6 and 7, Appellant points
out that Fujii selects two adjacent blocks for intrafield
interpolation if an error block is detected (brief, pages 10 & 11
and reply brief, pages 4 & 5). Appellant also indicates that the
claims recite coding of image signals by determining a
mathematical difference between macroblocks based on the
comparison of one macroblock to another (brief, page 13).
Additionally, Appellant argues that error flag 102 depicted in
Figure 5 of Fujii, as relied on by the Examiner (answer, page 3),
merely designates an error and is different from the claimed
difference bit that designates whether the coding is based on
macroblock intra-frame coding (brief, page 15).
In response to Appellant’s arguments, the Examiner asserts
that the argued features related to coding are not recited in the
claims (answer, pages 4 & 5). The Examiner further relies on
element 7 of Fujii (col. 3, lines 45-48 and col. 4, lines 17-22)
as an error correction encoding circuit and concludes that the
prior art relates to encoding data (answer, page 5). The
Examiner also argues that comparison steps S104-S107, shown in
Figure 7 of Fujii, are the same as the claimed step of
4
