Appeal No. 1996-2320
Application 08/221,224
Claim 2: The above discussion of claim 1 applies to the
elements of claim 2 which are in claim 1. In addition, Koch
teaches that the static mixers can fit vessels of any size and
shape (page 1) and can be made of intersecting corrugated
sheets forming open channels (page 2) which direct fluid
radially (page 7).
Claim 3: Adjacent Koch static mixers are positioned 90E
relative to each other (page 2).
Claim 4: Appellant’s statement that the product is
predominantly alkyl sulfonyl chloride when made at a
temperature of about -10 to about 50EC, and contains alkyl
sulfonic acid in a major amount when a higher reaction
temperature of about 85 to 115EC is used (specification, page
6, lines 16-20), indicates that Guertin’s product, which is
made at a temperature of about -10 to about 50EC (col. 1,
lines 40-41), contains some alkyl sulfonic acid. Guertin’s R
can be C alkyl, which encompasses C , and Guertin’s X can1-20 1-6
be hydrogen (col. 1, lines 52-55).
Claim 8: Guertin’s product is alkyl sulfonyl chloride
