Appeal No. 2003-0234
Application No. 09/446,202
builder in the type of composition disclosed by Murch ‘295. Two
such polycarboxylic acid salts are sodium ethylenediamine-
tetraacetate and potassium ethylenediaminetetraacetate as
disclosed by Murch ‘678 (col. 8, lines 56-59).
Claim 20
The appellants argue that Murch ‘295 does not disclose or
suggest a composition comprising a toxicologically-acceptable
suds suppressor (brief, page 5). The teaching in Murch ‘295 that
it is desirable that the composition is low sudsing (col. 2,
lines 42-43) would have fairly suggested, to one of ordinary
skill in the art, including in the composition a conventional
suds suppressor such as a toxicologically-acceptable silicone
which, as indicated by the appellants (specification, page 10),
was commercially available.
Conclusion
For the above reasons we conclude that the inventions
claimed in the appellants’ claims 1-21 would have been obvious to
one of ordinary skill in the art within the meaning of 35 U.S.C.
§ 103.
New ground of rejection
Claims 1-21 are rejected under 35 U.S.C. § 103 as being
unpatentable over Murch ‘678.
