Appeal No. 2002-0866
Application No. 09/262,471
by both the examiner and the appellants in support of their
respective positions. As a consequence of this review, we have
made the determinations which follow.
We turn first to the examiner’s rejection of Claims 1, 2, 6,
8 through 13, 15 through 17 and 20 under 35 U.S.C. § 102(b) as
anticipated by the disclosure of Delft. We find that Delft
exemplifies a mixture useful for imparting chicken flavor to
foods, inclusive of a pet food, wherein the mixture is produced
by combining, inter alia, L-cysteine hydrochloride, a
carbohydrate, such as dextrose or arabinose, and an animal digest
(chicken fat and powder chicken meat) at a reflux temperature (an
elevated temperature). See column 15, Examples XXIII-XXVII.
Although Delft exemplifies using L-cysteine hydrochloride as the
sulfur containing compound useful for forming the above-mentioned
mixture, it lists other sulfur containing compounds, such as
ammonium sulfide and hydrogen sulfide, which can be utilized for
the same purpose. See column 5, line 65 to column 6, line 51.
Delft also lists other equally useful carbohydrates, such as
d-xylose, ribose and sucrose. See column 7, lines 2-8.
