Appeal No. 2001-0647
Application 08/150,703
present invention include one or more of shellac, acrylics, epoxies,
alkyds, polyurethanes, linseed oil, and tung oil (page 5, lines 20-21).
...those compositions of the present invention which include a
pheromone, provide a controlled release of the
pheromone….controlled release may be augmented by incorporation
of certain high-molecular weight polymers which regulate the rate of
evaporation of the pheromone. (specification, page 7)
We recognize that the components enumerated in the claims are included in the
compositions because they provide certain functions. We also recognize that
certain components are able to serve more than one function in the claimed
composition as can be seen from Appellants’ specification and the teachings of the
cited prior art. For example, Quisumbing teaches that a polymer useful to control
pheromone release is an acrylic polymer. The present specification does not
provide any significant guidance as to the identity of “high molecular weight
polymers.” Since acrylics are described in the prior art as possessing the function
of the “high molecular weight polymers” of the claimed compositions and acrylics
are stated in the present specification to be a binder, it is reasonable to conclude
that acrylics serve to meet both the binder and high molecular weight polymer
requirements of the claims on appeal.
