Appeal No. 1997-1515
Application 08/361,891
THE REFERENCE2
Ahmed 4,992,192 Feb. 12,
1991
THE REJECTION
Claims 30-40, 42-44 and 49 stand rejected under 35 U.S.C.
§ 103 as being unpatentable over Ahmed.
OPINION
We have carefully considered all of the arguments
advanced by appellant and the examiner and agree with
appellant that the aforementioned rejection is not well
founded. Accordingly, we reverse this rejection.
We need to address only appellant’s claim 49, which is
the sole independent claim.
Ahmed discloses electrorheological fluids (col. 1, lines
4-5), which are “colloidal dispersions of polymeric particles
in a low conductivity continuous medium which show dramatic
changes in flow properties when exposed to an electric field”
2The examiner refers to Stangroom (U.S. 4,129,513) and
Chung (U.S. 4,994,198) in the examiner’s answer. These
references are not included in the statement of the rejection
and, therefore, are not properly before us. See In re Hoch,
428 F.2d 1341, 1342 n.3, 166 USPQ 406, 407 n.3 (CCPA 1970).
