Appeal No. 1998-0063
Application No. 08/057,805
if the alternative defects data area in the first sector is
full. The examiner states (Answer, page 8) that Harari's
substituting a replacement sector for a defective sector is
the motivation for creating a second relief area when a first
one is full. However, we fail to see how a teaching to
replace the entire sector would have motivated the skilled
artisan to create a second alternative defects area within the
same sector. The two methods for dealing with a full relief
area are quite different. Again the examiner has provided no
basis for the particular modification. Therefore, we cannot
sustain the rejection of claim 1 nor the claims grouped
therewith, claims 2 through 4, 7 through 14, 16, and 17.
