Appeal No. 2000-0345
Application No. 08/419,219
8. A method for controlling flying insects comprising the steps of:
a. providing an insect control article having a substrate with an essentially open
surface that is impregnated with an active insect control ingredient in a
structure such that the ingredient will readily passively evaporate when
exposed to air, wherein the active insect control ingredient is selected from
the group consisting of transfluthrin, prallethrin, vaporthrin, tefluthrin, and
combinations thereof;
b. placing the insect control article in an environment with air movement and
exposing the substrate of the insect control article thereto; and
c. allowing the active insect control ingredient impregnated within the substrate
to passively evaporate into the air in an environment free of added heat.
The examiner relies on the following reference:

In addition, we refer to the following references, which were made of record
during the prosecution of the instant application, and are referred to on pages 2 and 3 of
the specification, respectively.
Kauth et al. (Kauth) 4,796,381 Jan. 10, 1989
Clarke 2,720,013 Oct. 11, 1955
Claims 8-14 stand rejected under 35 U.S.C. § 102(b) as being anticipated by
Landsman. After careful review of the record before us, we reverse the rejection. We
do, however, conclude that the claims on appeal are unpatentable over the prior art of
record, and thus enter new grounds of rejection under 37 CFR § 1.196(b).
