Appeal No. 96-2708
Application 08/335,432
Additional matters
(1) If there is further prosecution of the merits in a continuation application, the
primary examiner should evaluate whether claim 6 satisfies 35 U.S.C. § 112, second
paragraph. Specifically, the examiner should note that claim 6, last two lines recite
“wherein the amount of zinc-containing compound is no more than 0.25% by weight of the
total weight of components B) C) and D).” No mention of B), C) and D) is made earlier in
claim 6.
(2) In addition, in the event of further prosecution in a continuation application, we
recommend that the examiner reevaluate the patentability of appellants’ claims in light of
Mafoti, U.S. Patent No. 5,158,607.
As noted by appellants(brief, page 5),
.... Mafoti... discloses active hydrogen containing mixtures of a polyol, a chain
extender containing amine groups or hydroxy groups, and an internal mold release
(IMR) agent comprising an ester having an acid number of 15 or less (column 1,
lines 31-46; column 4, line 35 through column 7, line 28; and claim 3 at column 11,
lines 16-35). The use of these active hydrogen group containing mixtures in a RIM
process is also disclosed.... (column 1, lines 32-35)
Mafoti also discloses the use of a three component catalyst system comprising a
zinc salt, tin salts and tertiary amine. (see examples 6 and 7).
