STATEMENT OF THE CASE
The Appellants appeal under 35 U.S.C. § 134 from the Examiner’s
decision finally rejecting claims 1, 7, 8, 10, 14, 15, and 21. Claims 17-20
have been cancelled. Claims 9 and 16 have been withdrawn. Claims 2-6,
11-13, and 22 have been objected to as being dependent upon a rejected base
claim, but would be allowable if rewritten in independent form including all
of the limitations of the base claim and any intervening claims. We have
jurisdiction over the appeal under 35 U.S.C. § 6(b).
We REVERSE.

REJECTIONS
The following Examiner’s rejections are before us for review.
Claims 1, 7, 10, 14, and 21 are rejected under 35 U.S.C. § 103(a) as
unpatentable over Wolf (US 3,147,964, issued Sept. 8, 1964) in view of
Bergdahl (US 6,416,030 B1, issued Jul. 9, 2002).
Claims 8 and 15 are rejected under 35 U.S.C. § 103(a) as unpatentable
over Wolf in view of Bergdahl as applied to claims 1 and 10, and further in
view of Dawda (US 5,941,511, issued Aug. 24, 1999).

CLAIMED SUBJECT MATTER
The claimed subject matter pertains to “an isolation mount used in
securing a support structure to a vehicle body, such as a vehicle cradle
mount or subframe, and for absorbing vibrations and movements between
the two structures.” Spec. 1.

Claims 1, 10, and 21 are the independent claims on appeal. Claim 1,
reproduced below with emphasis added, is illustrative of the subject matter
on appeal.
1. A mount assembly comprising:
an insert including a generally cylindrical
body having an aperture extending therethrough
and a first pair of radial projections and a second
pair of radial projections, said first pair of radial
projections extending at a distance greater than
said second pair of radial projections;
a microcellular urethane body disposed over
said insert; and
a cup member surrounding a portion of said
microcellular urethane body.

Claims 10 and 21 each recite “[a] mount assembly” including “an
insert . . . [and] a microcellular urethane body press-fit over said insert.”

OPINION
The Examiner has found that Wolf bushing “C” as shown in Figures
11-13 corresponds to the mount assembly as recited in independent claims 1,
10, and 21, except that Wolf’s polymer material “press-fit over said insert”
is made of elastic rubber not microcellular urethane. See Ans. 3-5. To
remedy this deficiency with respect to the independent claims the Examiner
turns to Bergdahl’s disclosure that “[v]arious materials such as natural
rubber compounds, microcellular urethanes, and other natural and synthetic
compounds and materials are suitable for elastomeric element 12 and other
elastomeric elements to be described later.” Ans. 4, citing Bergdahl, col. 3,
ll. 44-48. The Examiner concludes that “[i]t would have been obvious to

4
one of ordinary skill in the art to merely use the known microcellular
urethane into the mount of Wolf, as taught by Bergdahl et al., as a matter of
design choice depending upon the type of application in order to provide
different spring rates in different directions.” Ans. 4.
In rejecting claims under 35 U.S.C. § 103(a), the examiner bears the
initial burden of establishing a prima facie case of obviousness. In re
Oetiker, 977 F.2d 1443, 1445 (Fed. Cir. 1992). See also In re Piasecki, 745
F.2d 1468, 1472 (Fed. Cir. 1984). It is incumbent upon the examiner to
establish a factual basis to support the legal conclusion of obviousness. See
In re Fine, 837 F.2d, 1071, 1073 (Fed. Cir. 1988). In so doing, the examiner
must provide “some articulated reasoning with some rational underpinning
to support the legal conclusion of obviousness.” In re Kahn, 441 F.3d 977,
988 (Fed. Cir. 2006) (cited with approval in KSR Int’l Co. v. Teleflex, Inc.,
550 U.S. 398, 418 (2007)). Only if this initial burden is met does the burden
of coming forward with evidence or argument shift to the appellants. See
Oetiker, 977 F.2d at 1445.
Wolf’s bushing is an “elastic rubber bushing[] for automobile
suspensions and the like and more particularly to a durable elastic rubber
bushing having a spring rate in a vertical direction materially different from
its spring rate in a horizontal direction” and “is well suited for use in the
front suspension of a modern automobile where the rubber of the bushing is
employed to cushion angular deflections of low magnitude.” Col. 1, ll. 9-13,
and 30-33; see also fig. 1. Wolf discloses in Figures 11-13 bushing
assembly C, which includes a “cylindrical outer metal sleeve 8b having
radial end flanges 50 and a rounded oblate cross section, a tubular elastic
rubber insert 10b, and an inner metal sleeve 9b coaxial with the sleeve 8b

5
and having radially outward projecting ribs 56 on opposite sides thereof.”
Col. 4, ll. 4-9, figs. 11-13. Wolf’s bushing assembly C also includes
grooves 53 within an intermediate portion of bushing assembly C.
We note that the Examiner has found that that Wolf’s “elastic rubber
insert 10b (mounted between outer metal sleeve 8 and inner metal sleeve 9b)
is subjected to compression and tension when provided as rubber bushings
in automobile suspensions.” Ans. 6 (emphasis added).
Bergdahl is an elastomeric mounting/isolation assembly 10, especially
“for the undercarriage of a motor vehicle to isolate, or at least attenuate, the
influence of certain road induced forces on the vehicle body,” having an
elastomeric element 12 situated between the body and the chassis of the
vehicle. Abstract, col. 1, ll. 8-10, col. 2, ll. 1-24. Bergdahl’s elastomeric
element 12 is concentrically disposed within outer sleeve 16, wherein
suitable materials for elastomeric element 12 include “natural rubber
compounds, microcellular urethanes, and other natural and synthetic
compounds.” Col. 3, ll. 37-38, 44-48, fig. 1. As such, Bergdahl teaches that
natural rubber compounds and microcellular urethanes are alternative
materials for its particular purpose.
However, the Examiner has not established that Bergdahl’s
elastomeric element 12, which appears to only be subjected to compression
forces, is suitable for bearing the tension forces applied to Wolf’s tubular
elastic rubber insert 10b. Further, Bergdahl’s elastomeric element 12 does
not have a structural component that is a similar to Wolf’s groove 53. The
structure of groove 53, or a similar structural feature, is relevant in this case
because it could evidence a purpose of a structure to withstand tension
forces. See also App. Br. 5-7, Reply Br. 2. Therefore, the modification or

6
substitution of microcellular urethane, as taught by Bergdahl, for the rubber
material in Wolf would not have been a mere matter of design choice
because Bergdahl’s elastomeric element 12 and Wolf’s tubular elastic rubber
insert 10b appear to have different purposes. See In re Gal, 980 F.2d 717,
719-20 (Fed. Cir. 1992). Hence, the Examiner’s reasoning is not supported
by rational underpinning, and as such, the Examiner’s initial burden of
establishing a prima facie case of obviousness has not been met.
Thus, the rejection of independent claim 1 and its dependent claims 7
and 8, independent claim 10 and its dependent claims 14 and 15, and
independent claim 21, cannot be sustained.
As for the remaining rejection of claims 8 and 15, the Examiner finds
that “Dawda et al. teaches, as shown in fig. 2, the use of a cup member 16
with an end having a radially inwardly extending flange 40.” Ans. 5. This
finding does not remedy the lack of rational underpinning as discussed
above with respect to the rejection of the independent claims. Thus, the
rejection of dependent claims 8 and 15 as unpatentable over Wolf in view of
Bergdahl as applied to independent claims 1 and 10, and further in view of
Dawda, cannot be sustained.

DECISION
We REVERSE the rejections of claims 1, 7, 8, 10, 14, 15, and 21.
