pending claims, claims 1, 14, and 18 are independent; claim 1, reproduced
below, is illustrative of the claimed subject matter.
1. A shoe comprising an outsole extending from a heel end to a
toe end and from a medial side to a lateral side, the outsole
having a heel region, a midfoot region, a metatarsal region, and
a toe region, the heel region extending longitudinally from the
heel end to the midfoot region, the midfoot region extending
longitudinally from the heel region to the metatarsal region, the
toe region extending longitudinally from the toe end to the
metatarsal region, the outsole having a medial side region, a
central region, and a lateral side region, the medial side region
extending transversely from the medial side to the central
region, the lateral side region extending transversely from the
lateral side to the central region, the central region extending
transversely from the lateral side region to the medial side
region, the outsole having a bottom surface and a top surface,
the bottom surface of the outsole defining a concavity
extending longitudinally within the midfoot region and the
metatarsal region, the concavity extending transversely within
the central region, the concavity having a width at its widest
point that is between 45% and 55% the width of the outsole at
that point.

OPINION
Obviousness—Bjornson and Sokolowski
Claims 1–11
The Examiner finds that Bjornson discloses a shoe comprising an
outsole (sole element 300) having, in pertinent part, a bottom surface
“defining a concavity extending longitudinally within the midfoot region and
the metatarsal region (fig 6B and 6C), the concavity extending transversely
within the central region (the arch region extending transversely from medial
side to the lateral side).” Final Act. 3. In other words, it appears that the
Examiner reads the “concavity” of claim 1 on Bjornson’s deformable
longitudinal arch region, which comprises medial longitudinal cambered
arch 305 in a medial side of sole element 300 and lateral longitudinal
cambered arch 310 in a lateral side of the sole element 300, with the
intermediate region between the medial and lateral sides having a cambered
arch that blends between the medial and lateral arch shapes. See Bjornson
¶¶ 48, 49, 50; Figs. 6B, 6C.
Bjornson’s arch region does not satisfy the limitation that the
concavity have “a width at its widest point that is between 45% and 55% the
width of the outsole at that point” because it extends all the way from the
medial side to the lateral side of sole element 300. See Appeal Br. 18
(Claims App.); Bjornson ¶ 48 (describing the arch region as having a
Appeal 2021-004256

cambered arch that blends between the medial and lateral arch shapes). The
Examiner acknowledges that “Bjornson does not clearly show the concavity
having a width at its widest point that is between 45% and 55% the width of
the outsole at that point,” but finds that, “in the same field of endeavor,
Sokolowski teaches the concavity (fig 5, the concavity at the interior void
135) having a width at its widest point that is between 45% and 55% the
width of the outsole at the point.” Final Act. 4 (citing Sokolowski ¶ 53 and
noting that “the ratio between the width of the sole and the width across the
void is 2:1”). The Examiner reasons that it would have been obvious “to
modify the width of the concavity of Bjornson at its widest point [so] that
[it] is between 45% and 55% the width of the outsole at that point as taught
by Sokolowski for the benefit of enhancing cushioning and control[ling] foot
motions.” Final Act. 4.
Appellant argues, inter alia, that Sokolowski’s midsole void 135 is
irrelevant to the invention recited in Appellant’s claim 1, and that the
Examiner does not adequately explain why one would have been prompted
to modify Bjornson to arrive at the outsole recited in claim 1. Appeal Br. 6,
9. For the reasons that follow, we agree with Appellant that the Examiner
does not establish a sustainable case that the subject matter of claim 1,
particularly a shoe as claimed including an outsole having a bottom surface
“defining a concavity extending longitudinally within the midfoot region and
the metatarsal region, the concavity extending transversely within the central
region, the concavity having a width at its widest point that is between 45%
and 55% the width of the outsole at that point,” would have been obvious.
See Appeal Br. 18 (Claims App.).
Appeal 2021-004256
Application 16/208,190

As discussed above, Bjornson’s midfoot arch region comprises medial
longitudinal cambered arch 305 in a medial side of sole element 300 and
lateral longitudinal cambered arch 310 in a lateral side of the sole element
300, with the intermediate region between the medial and lateral sides
having a cambered arch that blends between the medial and lateral arch
shapes. Longitudinal cambered arches 305 and 310 of Bjornson’s midfoot
arch region are “configured to substantially conform to the shape of the
unloaded arch region of a foot.” Bjornson ¶ 49. The function of Bjornson’s
midfoot arch region is to “conformingly flatten[] and splay[] (e.g., elongate[]
in the longitudinal direction) along with the arch of the foot [upon loading
(e.g., upon the foot striking the ground during a walking or running gait)],
with the arch springing back to its curved unloaded configuration upon the
foot unloading (e.g., leaving the ground after the footstrike event).”
Bjornson ¶ 49.
Sokolowski’s interior void 135 is defined in midsole element 130 in
heel region 103. Sokolowski ¶¶ 41, 44, 45; Figs. 2, 5. Sokolowski does not
expressly explain the function of void 135, but the function of void 135, like
that of bores 136a-e, appears to be to vary the compressibility/stability
properties of the midsole in the location of the void. See Sokolowski ¶¶ 5, 6,
44, 49, 50. Sokolowski’s void 135 is not located in, or at least does not
extend substantially into, the arch area of the sole and is not pertinent to
causing a flattening or splaying of the sole along the arch of the foot during
loading or a springing back during unloading. Thus, it is not clear why
Sokolowski’s teachings regarding the width of void 135 relative to the width
of heel region midsole element 130 would be at all instructive in regard to
the construction or configuration of Bjornson’s deformable longitudinal arch

region, which extends across the entire width of Bjornson’s sole element
300, with the intermediate region between the medial and lateral sides
having a cambered arch that blends between medial longitudinal cambered
arch 305 in a medial side of sole element 300 and lateral longitudinal
cambered arch 310 in a lateral side of the sole element 300. Bjornson ¶ 48.
More particularly, it is not apparent why a person having ordinary skill in
the art would have been prompted by the combined teachings of Bjornson
and Sokolowski’s void 135 to modify the width of the longitudinal arch
region of Bjornson to be between 45% and 55% the width of the outsole at
its widest point. The Examiner’s articulated reason for the modification is
that this would provide “the benefit of enhancing cushioning and
control[ling] foot motions” (Final Act. 4), but the Examiner does not
adequately explain, nor is it apparent, why modifying Bjornson’s arch region
so that it has a width at its widest point that is between 45% and 55% the
width of the outsole at that point, rather than extending across the entire
width of the sole element in that region, would enhance cushioning or better
control foot motions.
The Examiner finds that Appellant does not point out the criticality of
the particular width percentage claimed. Ans. 4. Appellant’s Specification
discloses that “the concavity . . . , depression, channel, or the like” is wider
than a typical groove or sipe, and, thus, “[r]ather than providing flexibility or
traction as a typical groove or sipe, . . . provides the flex and/or restorative
force described,” for example, in paragraph 22 of the Specification, “and/or
otherwise increases the comfort of the wearer.” Spec. ¶ 33. The
Specification then discloses:
Appeal 2021-004256
Application 16/208,190

7
For example and without limitation, the channel has a width at
its widest point that is at least between 20% and 30% the width
of the outsole 22 at that point. More preferably, the channel has
a width at its widest point that is at least between 30% and 50%
the width of the outsole 22 at that point. Still more preferably,
the channel has a width at its widest point that is at least
between 50% and 80% the width of the outsole 22 at that point.
In some embodiments, the channel has a width as described
above not only at the widest point but for at least between 20%
and 30% of the longitudinal length of the outsole 22. More
preferably, the above described widths extend for at least
between 30% and 50% of the longitudinal length of the
outsole 22.
Spec. ¶ 33. The Specification also discloses that the concavity “extends
laterally within the central region 44,” which “extends laterally between the
lateral side region and the medial side region for a substantial distance”2 and
“has a width greater than a sipe, groove, or other feature inset into the
outsole 22.” Spec. ¶ 23.
Based on the aforementioned description of the concavity in
Appellant’s Specification, one of ordinary skill in the art would understand
that the concavity extends a substantial distance laterally across the width of
the outsole, within the central region thereof, but does not extend to the
medial or lateral side of the outsole, in order to provide the desired
spring-like absorption or dampening of impact and restorative force
discussed in paragraph 22 of the Specification. Thus, although we agree
with the Examiner that Appellant’s Specification does not disclose, much
less demonstrate, any criticality to the particular numerical width range
claimed (i.e., between 45% and 55% the width of the outsole at its widest

2 Appellant’s Specification defines “the term region [as referring] to a
margin or area as opposed to the term end.” Spec. ¶ 23.
Appeal 2021-004256
Application 16/208,190

8
point), the Specification indicates criticality to the concavity being wider
than a typical groove or sipe and suggests an intention for the concavity to
have a width at its widest point that is less than the width of the outsole at
that location (i.e., the concavity extending less than the full width of the
outsole). As discussed above, the Examiner does not adequately explain,
nor is it apparent, why modifying Bjornson’s arch region so that it has a
width at its widest point that is less than the width of the outsole at that
point, much less a width between 45% and 55% the width of the outsole at
its widest point as claimed, rather than extending across the entire width of
the sole element in that region, would enhance cushioning or better control
foot motions.
The Examiner directs our attention to interior void 315 extending
transversely in Bjornson’s midsole as shown in Figure 6E. Ans. 3–4. To the
extent that the Examiner intends to rely on Bjornson’s void 315, alone, as
the claimed “concavity,” void 315 as shown in Figures 6A, 6E, and 6F
would not satisfy the limitation in claim 1 that the concavity extend
“longitudinally within the midfoot region and the metatarsal region.”
Rather, as illustrated in Figure 6A, void 315 extends only within the midfoot
region, terminating rearward of the metatarsal region. To the extent that the
Examiner intends to rely on void 315 in combination with the midfoot arch
region (the longitudinal cambered arch), this position suffers from the
shortcoming discussed above. Although void 315 may define the deepest
portion of a concavity comprising the cambered arch and void 315, even if
one were to modify the width of Bjornson’s void 315 in view of Sokolowski,
the concavity (i.e., the longitudinal cambered arch portion) would still
extend transversely across the entire width of the sole element, thereby

Application 16/208,190

having a width at its widest point that is 100% of the width of the sole
element at this point.
Further, the Examiner points out that “Bjornson also teaches one
embodiment of the invention may include cambered arches in other portions
of the foot and or in other configurations, in addition to, or in place of
longitudinal cambered arches in the midfoot region.” Ans. 4 (citing
Bjornson ¶ 52). Bjornson indeed teaches that the sole “may include
cambered arches in other portions of the foot or in other configurations.”
Bjornson ¶ 52. Bjornson further discloses one embodiment of the sole
element comprising transverse cambered arch 400 in forefoot region 155 “to
support and conformingly adapt[] to a deformation of the forefoot (for
example a transverse flattening and splaying of the forefoot region at and
around the metatarsal heads).” Bjornson ¶ 52; Fig 6D. Transverse
cambered arch 400 has a curved profile when unloaded and deflects
downward during loading “to conformingly flatten and splay along with the
metatarsal head region of the foot.” Bjornson ¶ 52. This transverse
cambered arch in the particular embodiment that Bjornson discusses is
disposed in the forefoot region of the sole element and does not extend
“longitudinally within the midfoot region,” as called for in claim 1. Appeal
Br. 18 (Claims App.). The Examiner does not adequately explain why it
would have been obvious, in view of Bjornson’s broad teaching of
“cambered arches in other portions of the foot or in other configurations” of
the sole, or the particular embodiment of such a cambered arch (transverse
cambered arch 400) in the forefoot region, to provide a transverse cambered
arch extending “longitudinally within the midfoot region and the metatarsal

Application 16/208,190

10
region,” with a width between 45% and 55% the width of the outsole at its
widest point, as called for in claim 1. Appeal Br. 18 (Claims App.).
For the above reasons, the Examiner does not set forth the requisite
factual findings and reasoning to establish a sustainable case of obviousness
of the subject matter of claim 1. Accordingly, we do not sustain the
rejection of claim 1 or its dependent claims 2–11 as being unpatentable over
Bjornson and Sokolowski.
Claims 14–17
In addressing claim 14, the Examiner finds that Bjornson discloses, in
Figures 6A through 6F, an outsole having a depression within the central
region and the midfoot region thereof, “the depression having [a] curved
shape from lateral side to medial side.” Final Act. 7. The Examiner
acknowledges that “Bjornson does not clearly show the depression having a
width at its widest point that is between 45% and 55% the width of the
outsole at that point,” but determines that it would have been obvious “to
modify the width of the depression of Bjornson at its widest point [so] that
[it] is between 45% and 55% the width of the outsole at that point as taught
by Sokolowski for the benefit of enhancing cushioning and control[ling] foot
motions.” Final Act. 7.
Aside from referencing Figures 6A through 6F, the Examiner does not
specify what feature of Bjornson’s sole element 300 corresponds to the
“depression” of claim 14. However, the Examiner’s annotated version of
Bjornson’s Figure 6E on page 8 of the Final Office Action, provided by the
Examiner in addressing claim 15, which depends from claim 14, indicates
that the Examiner relies on the combination of the midfoot longitudinal
cambered arch and void 315 as corresponding to the depression. In
Appeal 2021-004256
Application 16/208,190

11
particular, the Examiner’s use of arrows to show the depth (or height) of the
depression in the central portion (i.e., within void 315) and the depths of the
depression in the medial and lateral portions of the longitudinal cambered
arch (in the region between void 315 and medial longitudinal cambered arch
305 and in the region between void 315 and lateral longitudinal cambered
arch 310) suggests that the Examiner relies on the depression defined by the
arch and void 315 relative to the ground contacting portions of the sole
element.3
The Examiner’s rejection of claims 14–17 thus suffers from the
deficiency discussed above in regard to the rejection of claim 1. More
specifically, although void 315 may define the deepest portion of a
depression comprising the cambered arch and void 315, even if one were to
modify the width of Bjornson’s void 315 in view of Sokolowski, the
depression would still extend across the entirety of the width of the sole
element, thereby having a width at its widest point that is 100% of the width

3 To the extent that the Examiner may be relying on some other feature, or
combination of features, illustrated in Bjornson’s Figures 6A through 6F as
the “depression” of claim 14, it is not the Board’s place to speculate on how
the Examiner reads claim 14 on the structure of Bjornson. A rejection must
be set forth in sufficiently articulate and informative manner as to meet the
notice requirement of 35 U.S.C. § 132, such as by identifying where or how
each limitation of the rejected claims is met by the prior art references. In re
Jung, 637 F.3d 1356, 1363 (Fed. Cir. 2011); see also 37 C.F.R. § 1.104(c)(2)
(“When a reference is complex or shows or describes inventions other than
that claimed by the applicant, the particular part relied on must be designated
as nearly as practicable. The pertinence of each reference, if not apparent,
must be clearly explained and each rejected claim specified.”); In re Stepan,
660 F.3d 1341, 1345 (Fed. Cir. 2011) (explaining that it is the PTO’s
obligation “to provide prior notice to the applicant of all ‘matters of fact and
law asserted’ prior to an appeal hearing before the Board”).

of the sole element at this point. The Examiner does not adequately explain,
nor is it apparent, why modifying Bjornson’s arch region so that it has a
width at its widest point that is between 45% and 55% the width of the
outsole at that point, rather than extending across the entire width of the sole
element in that region, would enhance cushioning or better control foot
motions. See Appeal Br. 12 (arguing the Examiner fails to explain why the
proposed modification would have been obvious in view of Sokolowski).
In responding to Appellant’s arguments against the rejection of claim
14, just as in the Examiner’s response to Appellant’s arguments against the
rejection of claim 1, the Examiner points out that “Bjornson also teaches one
embodiment of the invention may include cambered arches in other portions
of the foot and or in other configurations, in addition to, or in place of
longitudinal cambered arches in the midfoot region.” Ans. 7 (citing
Bjornson ¶ 52). However, the Examiner does not adequately explain why it
would have been obvious, in view of Bjornson’s broad teaching of
“cambered arches in other portions of the foot or in other configurations” of
the sole, or the particular embodiment of such a cambered arch (transverse
cambered arch 400) in the forefoot region, to provide a cambered arch
within “the midfoot region” as called for in claim 14. Appeal Br. 20–21
(Claims App.).
Accordingly, we do not sustain the rejection of claims 14–17 as being
unpatentable over Bjornson and Sokolowski.
Claim 18
The Examiner finds that Bjornson discloses a shoe comprising an
outsole having a bottom surface extending upward from the medial and
lateral side regions into the central region, and upward from the metatarsal
Appeal 2021-004256
Application 16/208,190

13
and heel regions into the midfoot region, to define a depression. Final Act. 9
(citing Bjornson, Figs. 6B, 6D, 6E). The Examiner finds that Bjornson does
not explicitly disclose the depression being defined at least partially by three
inflection points as called for in claim 18 or the depression having a width at
its widest point that is between 45% and 55% of the width of the outsole at
that point. Final Act. 9–10.
Referring to an annotated Figure 6E on page 10 of the Final Office
Action, the Examiner reasons that it would have been obvious “to recognize
that the depression further being defined at least partially by three inflection
points about which the bottom surface curves as it extends laterally for the
benefit of providing a more conforming adaptive flexion during loading and
unloading of the foot.” Final Act. 9. As evident from the Examiner’s
annotated Figure 6E, the Examiner relies on the depression defined by the
arch and void 315 relative to the ground contacting portions of the sole
element as the “depression” of claim 18. The Examiner’s rejection of claim
18 thus suffers from the deficiency discussed above in regard to the rejection
of claims 1 and 14. Moreover, the Examiner does not cite any evidence to
support the finding that those skilled in the art would recognize that defining
a depression in Bjornson’s sole element 300 by a curved bottom surface, as
drawn in by the Examiner in the annotated version of Figure 6E, would
provide a more conforming adaptive flexion during loading and unloading of
the foot. See Appeal Br. 15 (arguing that “[t]he [E]xaminer’s addition of a
curved line to Figure 6E of Bjornson applies impermissible hindsight”).
Accordingly, we do not sustain the rejection of claim 18, or its dependent
claims 19 and 20, as being unpatentable over Bjornson and Sokolowski.
Appeal 2021-004256
Application 16/208,190

14
Obviousness—Bjornson, Sokolowski, and Henderson
In rejecting claims 12 and 13, which depend from claim 1, the
Examiner relies on Henderson for its teaching of substantially rectangular
indentations (i.e., traction elements) extending upward from the bottom
surface of the sole element within the medial and lateral side regions
alternating with a plurality of sipes. Final Act. 11–12. The Examiner does
not set forth any additional findings or reasoning that would remedy the
aforementioned shortcomings of the rejection of claim 1. Accordingly, we
do not sustain the rejection of claims 12 and 13 as being unpatentable over
Bjornson, Sokolowski, and Henderson.
CONCLUSION
The Examiner’s rejections of claims 1–20 under 35 U.S.C. § 103 are
REVERSED.
