Appeal No. 1996-3673
Application No. 08/139,893
that the disclosure of Moyer at column 1, lines 55 to column 2
,line 2 in combination with the disclosure of Moyer at column
6, lines 2-4 constitutes a teaching of a genus of reaction
products that includes appellants’ claimed subgenus of
alkylenepolyamine/formaldehyde reaction product scavengers.
However, even considering the teachings of the “secondary
references” of Wilson and Go which teach the related use of
alkylenepolyamine compounds (not reaction products), it is
apparent that there is inadequate guidance and direction in
the prior art that would have led a person of ordinary skill
in this art to the selection of appellants’ claimed subgenus
of “scavenger” reaction products.
Based on the above, we are constrained to agree with
appellants that the relevant combined teachings of the relied
upon references do not establish a prima facie case of
obviousness for the subject matter defined by the herein
appealed claims.
The decision of the examiner is reversed.
REVERSED
