Application No. 08/077,599
zones in the process of Cheng inasmuch as the ratios in
question also are dependent on the amount of carbon black
produced. On this record, appellant simply has not pointed to
any objective evidence to demonstrate that the fuel/carbon
black ratios (fuel saving) resulting in Cheng’s process do not
necessarily result in the broadly recited fuel/carbon black
ratios recited in the claimed step (d). See Brief in its
entirety.
In view of the foregoing, we affirm the examiner’s
decision rejecting all of the claims on appeal under 35 U.S.C.
§ 103.
No time period for taking any subsequent action in
connection with this appeal may be extended under 37 CFR
§ 1.136(a).
