Appeal 2007-1669
Application 10/434,038
Examiner cites the Lashley reference for describing that the particular amine
compounds of the claims are known to be suitable for reaction with acrolein
(Answer 7). Appellants have not challenged this teaching of the reference.
As stated above, a person of ordinary skill in the art would have reasonably
expected that in a non-aqueous waste stream comprising an aldehyde or
ketone a chemical reaction between the aldehyde or ketone with a polyamide
or nitrogen containing compound would occur.
For the reasons set forth above and in the Answer we affirm the
rejection of claims 1-5, 7-13, 15-22, and 24-26. As a final point with respect
to the § 103 rejections, we note that Appellants base no argument upon
objective evidence of nonobviousness, such as unexpected results.
ORDER
The rejection of claims 1-5, 7-13, 15-22, and 24-26 under 35 U.S.C.
§ 103(a) is affirmed.
No time period for taking any subsequent action in connection with
this appeal may be extended under 37 C.F.R. § 1.136(a)(1)(iv)(2006).
