Appeal No. 1996-2320
Application 08/221,224
(col. 1, lines 3-4). Guertin’s R can be C alkyl, which
1-20
encompasses C , and Guertin’s X can be hydrogen (col. 1,
1-6
lines 52-55).
Claim 9: Guertin’s temperature range is about -10 to
about 50EC (col. 1, lines 40-41).
Claim 10: Guertin’s feed rate range is at least about
0.005 lbmole/hr-ft , preferably about 0.005 to about3
0.03 lbmole/hr-ft (col. 3, lines 40-46). Depending on the3
length of the reactor, this range may be lower than
appellant’s recited range of about 0.5 to about 8.0 lbmole/hr-
ft . However, the teaching by Koch that use of a static mixer2
provides “consistent, predictable mixing performance,
regardless of flow rate or equipment dimensions” (page 2)
would have fairly suggested, to one of ordinary skill in the
art, using higher feed rates, such as those recited by
appellant, when Guertin’s reactor contains a static mixer.
Claim 11: Guertin teaches that R can be methyl (col. 1,
line 55).
Claim 12: Appellant’s statement that the product is
predominantly alkyl sulfonyl chloride when made at a
