Collabo Innovations, Inc. (“Collabo”) appeals from the

COLLABO INNOVATIONS, INC. v. SONY CORPORATION 3
final written decisions of the Patent Trial and Appeal
Board (“Board”) in two inter partes reviews, each finding
claims 1–18 of U.S. Pat. No. 7,023,034 (“the ’034 patent”)
unpatentable. Because we agree with the Board that Col-
labo did not present a timely claim construction argument,
and because substantial evidence supports the Board’s
findings regarding the prior art, we affirm.
I
Collabo owns the ’034 patent, which is generally di-
rected to a “solid-state imaging device in which a plurality
of light-sensitive elements are arranged in a matrix form.”
’034 patent col. 1 ll. 7–10. Relevant to this appeal, the ’034
patent describes and claims a pair of “reflecting walls” that
exist over each light-sensitive element (such as a photodi-
ode), partitioning each element from neighboring light-sen-
sitive elements. Light that approaches the photodiode at
an oblique angle, which might otherwise be inadvertently
received by an adjacent photodiode, instead reflects off of
the reflecting walls onto the aperture of the desired photo-
diode, preventing color mixing and minimizing variation
across the image.
Sony Corporation (“Sony”) filed two petitions for inter
partes review of the ’034 patent. The first petition alleged
that each of claims 1–18 was either anticipated by Japa-
nese Patent Application Publication No. 2001-237404 (“To-
moda”), or obvious over Tomoda in view of various
additional references including, inter alia, Japanese Pa-
tent Application Publication No. H11-087674 (“Abe”). Sony
Corp. v. Collabo Innovations, Inc., No. IPR2017-00958, Pa-
per 31, at 10 (PTAB Aug. 31, 2018) (“-958 Decision”). The
second petition alleged that the same claims were rendered
obvious by U.S. Patent Application Publication No.
2001/0026322 (“Takahashi”) in view of various secondary
references including Abe. Sony Corp. v. Collabo

4 COLLABO INNOVATIONS, INC. v. SONY CORPORATION
Innovations, Inc., No. IPR2017-00960, Paper 31, at 10
(PTAB Aug. 31, 2018) (“-960 Decision”). 1
The Board instituted trial on both petitions, held a
consolidated hearing, and issued separate final written
decisions concluding that claims 1–18 are unpatentable
under each set of grounds. The decisions were unanimous
with respect to claims 1, 2, 4–11, and 13–18. With respect
to claims 3 and 12, a majority of the Board concluded that
Abe discloses the claim limitation “wherein a vertical cross
section of the reflecting wall is a trapezoid whose upper
base is longer than a lower base.” Administrative Patent
Judge Anderson dissented in each case and would have
found claims 3 and 12 not unpatentable. -958 Decision at
69; -960 Decision at 72.
Collabo timely appealed the Board’s decisions. We
have jurisdiction under
28 U.S.C. § 1295(a)(4)(A).
II
Collabo presents two arguments on appeal. First, it ar-
gues that the Board erred by adopting an unreasonably
broad construction of “reflecting walls,” and therefore its
decision with respect to all claims must be reversed. Ap-
pellant’s Br. 32. Second, Collabo argues that the Board’s
decision with respect to claims 3 and 12 must be reversed
for the additional reason that the Board’s finding that Abe
1 Sony’s two petitions are largely identical for the
purposes of this appeal. For clarity, this opinion refers to
the Board decisions, procedural history, briefing, and joint
appendix of the -958 IPR (Appeal No. 19-1154) except
where otherwise noted.

discloses a trapezoidal reflecting wall is not supported by
substantial evidence.
Id. at 49. We address each in turn. 2
A
During an inter partes review, claims are given their
broadest reasonable interpretation consistent with the
specification. Cuozzo Speed Techs., LLC v. Lee,
136 S. Ct.
2131, 2146 (2016). 3 Applying that standard, the Board con-
strued the term “reflecting walls” as “structures having ap-
proximately vertical surfaces that reflect light.” -958
Decision at 16. Collabo now argues that this was unrea-
sonably broad, and the Board should have given the term
its “plain and ordinary meaning,” which it contends is “a
wall that reflects oblique light from a micro lens onto a cor-
responding light-sensitive element.” Appellant’s Br. 43.
Sony responds that Collabo waived its claim construction
argument by failing to raise it before the Board in a timely
2 In its opening brief, Collabo also argued that the
Board’s application of inter partes review to patents issued
before the passage of the Leahy-Smith America Invents Act
was an unconstitutional taking or a violation of due pro-
cess. Appellant’s Br. 54–50. Prior to Collabo’s reply brief,
however, this court issued Celgene Corporation v. Peter,
concluding that such actions were not unconstitutional.
931 F.3d 1342, 1362–63 (Fed. Cir. 2019). Collabo conceded
on reply that its arguments were “foreclosed by the Court’s
recent precedent in Celgene” and related cases. Appellant’s
Reply Br. 28. We agree, and therefore do not further ad-
dress Collabo’s constitutional argument.
3 Although this standard has changed, the broadest
reasonable interpretation continues to apply to petitions,
like those at issue here, filed before November 13, 2018.
See Changes to the Claim Construction Standard for Inter-
preting Claims in Trial Proceedings Before the Patent Trial
and Appeal Board,
83 Fed. Reg. 51,340 (Oct. 11, 2018) (cod-
ified at 37 C.F.R. pt. 42).
Case: 19-1152 Document: 68 Page: 6 Filed: 02/25/2020

manner, and that in any case the Board’s construction was
correct. It notes that Collabo did not raise any claim con-
struction challenge until the hearing before the Board, and
the Board found that untimely challenge “expressly or im-
pliedly waived.” Appellee’s Br. 21 (quoting -958 Decision
at 16).
Decisions related to compliance with the Board’s proce-
dures are reviewed for an abuse of discretion.” Intelligent
Bio-Systems, Inc. v. Illumina Cambridge, Ltd.,
821 F.3d
1359, 1367 (Fed. Cir. 2016). The Board’s authority to con-
sider timely arguments, and to find untimely arguments
waived, is a matter of compliance with
37 C.F.R. § 42.5 and
the Office Patent Trial Practice Guide,
77 Fed. Reg. 48,756,
48,768 (Aug. 14, 2012), which states that “[n]o new evi-
dence or arguments may be presented at the oral argu-
ment.” See Dell Inc. v. Acceleron, LLC,
884 F.3d 1364, 1369
(Fed. Cir. 2018). Therefore, the Board’s decision to find an
argument waived, as it did in this case, is reviewed for an
abuse of discretion. See
id. (applying abuse of discretion
standard to Board’s refusal to consider “untimely argu-
ment”).
In its IPR petition, Sony proposed that the term “re-
flecting walls” be construed as “structures having approxi-
mately vertical surfaces that reflect light.” J.A. 92. Collabo
did not contest this construction in its patent owner pre-
liminary response. J.A. 594 (“[F]or the purposes of this
Preliminary Response, Patent Owner does not offer a con-
struction for any of the claim terms in the ’034 patent.”).
On that record, “and based on the [s]pecification,” the
Board preliminarily adopted Sony’s construction in its in-
stitution decision. J.A. 779.
Following the Board’s institution decision, Collabo
again declined to contest Sony’s construction or the Board’s
adoption of that construction. In its patent owner re-
sponse, Collabo stated that it had “applie[d] the Board’s
construction for its analysis.” J.A. 874. Similarly,
Case: 19-1152 Document: 68 Page: 7 Filed: 02/25/2020
COLLABO INNOVATIONS, INC. v. SONY CORPORATION 7
Collabo’s expert testified that he “applied the constructions
recommended by the board,” but “doesn’t agree or disagree”
with them. J.A. 1274. Collabo expressly reserved the right
“to seek alternative constructions in other proceedings and
matters,” but did not indicate that it was challenging the
Board’s construction in this proceeding. J.A. 874 (empha-
sis added).
At the hearing before the Board, however, Collabo nev-
ertheless attempted to challenge the Board’s claim con-
struction. See J.A. 1500 (“disagree[ing]” with “the current
construction that has been preliminarily adopted by the
Board”). When pressed, Collabo conceded that it had not
previously alerted the Board to its claim construction chal-
lenge, and that its claim construction challenge “is not in
the record.” J.A. 1499. Following the hearing, Collabo filed
a motion requesting additional briefing on the construction
of reflecting walls. See J.A. 1465. The Board denied this
motion, noting that Collabo “had ample opportunity to ar-
gue for an alternative construction” in its patent owner re-
sponse but “did not do so.” J.A. 1466.
In its final written decision, the Board reiterated that
Collabo had not raised a timely claim construction argu-
ment and concluded that Collabo “expressly or impliedly
waived any argument contrary to the preliminary con-
struction from the Institution Decision.” -958 Decision at
13. After further considering the claim language, the spec-
ification, and the prosecution history, the Board formally
adopted Sony’s proposed construction of reflecting walls
and performed its obviousness analysis under that con-
struction.
Id. at 15–16.
On this record, we agree with Sony that the Board did
not abuse its discretion when it declined to consider Col-
labo’s claim construction argument. Collabo admitted at
the hearing that it had not previously raised this argu-
ment. J.A. 1499. And neither Collabo’s patent owner pre-
liminary response nor its patent owner response contain a
Case: 19-1152 Document: 68 Page: 8 Filed: 02/25/2020
8 COLLABO INNOVATIONS, INC. v. SONY CORPORATION
facial challenge to Sony’s proposed claim construction or
the Board’s adoption of that construction. See J.A. 594,
874. Accordingly, Collabo did not properly present its
claim construction argument before the Board and is not
entitled to present that argument before us. See In re Bax-
ter Int’l,
678 F.3d 1357, 1362 (Fed. Cir. 2012) (“Absent ex-
ceptional circumstances, we generally do not consider
arguments that the applicant failed to present to the
Board”) (internal citations omitted).
Collabo’s argument to the contrary is not persuasive.
It primarily relies on our non-precedential opinion in Inter-
tainer, Inc. v. Hulu, LLC, 660 F. App’x 943 (Fed. Cir. Sept.
26, 2016) for the proposition that a party’s claim construc-
tion arguments on appeal are not waived so long as they
are “consistent with those it made to the Board.” Appel-
lant’s Br. 43–44. We disagree that Intertainer presents the
same situation as this case. In Intertainer, this court con-
cluded that a party’s claim construction challenge was not
waived because, although framed differently, it took “the
same position” before the Board that it took on appeal. 660
F. App’x at 947. As we noted, the “original scope of Inter-
tainer’s claim construction position” had not changed.
Id.
at 948.
The same cannot be said for Collabo’s position here. In
its patent owner response and patent owner preliminary
Response, Collabo acquiesced to Sony and the Board’s con-
struction, and expressly applied that construction in its
analysis. Now, on appeal, it argues that this construction
was incorrect, and the term should be accorded its “plain
and ordinary meaning.” Appellant’s Br. 28. And, for the
first time, Collabo specifies that this plain and ordinary
meaning is “a wall that reflects oblique light from a micro
lens onto a corresponding light-sensitive element.” Appel-
lant’s Br. 42–43. Because Collabo’s new claim construction
argument on appeal does not present “the same position” it
took below, Intertainer is inapplicable.
Case: 19-1152 Document: 68 Page: 9 Filed: 02/25/2020
COLLABO INNOVATIONS, INC. v. SONY CORPORATION 9
Because Collabo did not raise its claim construction ar-
gument below, that argument is waived, and we need not
address its merits on appeal.
B
Independent of its claim construction argument, Col-
labo challenges the Board’s conclusion that the prior art
renders claims 3 and 12 obvious. Claims 3 and 12 each
recite the dependent limitation “wherein a vertical cross
section of the reflecting wall is a trapezoid whose upper
base is longer than a lower base.” Collabo does not dispute
that the Abe reference discloses a vertical cross section of a
reflecting wall, but argues that substantial evidence does
not support the Board’s conclusion that the cross section
disclosed in Abe is a trapezoid.
“We review the PTAB’s factual findings for substantial
evidence and its legal conclusions de novo.” Redline Detec-
tion, LLC v. Star Envirotech, Inc.,
811 F.3d 435, 449 (Fed.
Cir. 2015) (citation omitted). While obviousness is ulti-
mately a question of law, it is based on underlying findings
of fact. In re Gartside,
203 F.3d 1305, 1316 (Fed. Cir. 2000).
As relevant here, the Board’s findings regarding “the scope
and content of the prior art” are reviewed for substantial
evidence.
Id. at 1319 (internal quotation omitted). “Sub-
stantial evidence is something less than the weight of the
evidence but more than a mere scintilla of evidence. It is
such relevant evidence as a reasonable mind might accept
as adequate to support a conclusion.” In re NuVasive, Inc.,
842 F.3d 1376, 1379–80 (Fed. Cir. 2016) (internal citations
and quotations omitted). “‘If the evidence in the record will
support several reasonable but contradictory conclusions,
we will not find the Board’s decision unsupported by sub-
stantial evidence simply because the Board chose one con-
clusion over another plausible alternative.’” Redline, 811
F.3d at 449 (quoting In re Jolley,
308 F.3d 1317, 1320 (Fed.
Cir. 2002)).
Case: 19-1152 Document: 68 Page: 10 Filed: 02/25/2020
10 COLLABO INNOVATIONS, INC. v. SONY CORPORATION
In its petition, Sony relied primarily on Figure 3 of Abe
and the accompanying description to teach the “is a trape-
zoid” limitation. Figure 3 of the English translation of Abe
is reproduced below:
J.A. 461. Sony’s petition further explained that element 9
is a “second light shielding film,” having “lateral faces 9a”
that are approximately vertical surfaces, and upper ex-
tended portions 92. J.A. 122–123 (citing Abe ¶¶ 38, 47).
Sony provided the following annotation of Figure 3 to sup-
port its contention that this figure discloses a trapezoidal
reflecting wall:
Case: 19-1152 Document: 68 Page: 11 Filed: 02/25/2020
COLLABO INNOVATIONS, INC. v. SONY CORPORATION 11
J.A. 122. As Sony explained:
Abe recites that “upper extended portions 92 may
be extended so as to incline upwardly from the up-
per ends of the lateral faces 9a of the second light
shielding film 9.” ([Abe], ¶0044)([Expert declara-
tion], ¶146). This describes that the vertical cross
section of the reflecting wall is a trapezoid whose
upper base is longer than a lower base, as seen in
Fig. 3. ([Expert declaration], ¶146).
J.A. 123. Sony cited to the declaration of its expert, who
opined that these passages of Abe, “as shown in Abe’s Fig-
ure 3 . . . disclose[] that the vertical cross section of the re-
flecting wall is a trapezoid whose upper base is longer than
a lower base.” J.A. 263–64. Based on this explanation, the
Board correctly explained in its final written decision that
Sony “has identified, through its annotations, what it con-
tends are the boundaries of Abe’s trapezoidal reflecting
wall, namely, the lateral faces of light shielding film 9, the
bottom surface of light shielding film 9, and the top surface
of second insulating film 14 within the interior of light
Case: 19-1152 Document: 68 Page: 12 Filed: 02/25/2020
12 COLLABO INNOVATIONS, INC. v. SONY CORPORATION
shielding film 9.” -958 Decision at 41 (citing Abe ¶¶ 38–
39).
The Board acknowledged Collabo’s counter-argument
that Abe does not disclose a trapezoid. “Petitioner relies on
Abe’s U-shaped design or the cup shape or bowl-shaped de-
sign of these walls . . . Patent Owner argues that there is
no top to Abe’s structure and, because it is a cup, it is not a
trapezoid.” -958 Decision at 43–44. Collabo provided the
following annotation to represent its preferred reading of
Abe:
-960 Decision at 46; see also -958 Decision at 44 (incorpo-
rating Collabo’s arguments from the ’960 IPR). 4 As the
Board noted, Collabo and its expert contended that the
striped green lines “represent transparent insulation 14 of
Abe.” -960 Decision at 46.
4 The 26 degree angle measurement depicted in this
annotation correlates to an unrelated argument made be-
low, which Collabo does not pursue on appeal.
Case: 19-1152 Document: 68 Page: 13 Filed: 02/25/2020
COLLABO INNOVATIONS, INC. v. SONY CORPORATION 13
After weighing both parties’ positions, the Board found
that Abe does disclose a trapezoid. Citing Sony’s petition,
as well as the same portions of Abe cited in Sony’s petition,
the Board determined that “the entire cup shaped struc-
ture, including the material within, is the recited ‘reflect-
ing wall.’” -958 Decision at 45. As a result, “Abe’s
description [of Figure 3] . . . describes that the vertical cross
section of the reflecting wall is a trapezoid.”
Id. (citing Abe
¶ 44, Sony’s petition, and the declaration of Sony’s expert).
Collabo argues that we must reverse the Board because
this finding was not supported by substantial evidence. We
disagree. The Board was presented with two alternative
interpretations of Abe, both supported by citations to Fig-
ure 3, the text of the reference, and expert testimony. The
question before us is not which of these interpretations we
would find more compelling in a vacuum. “[I]t is not for us
to second-guess the Board’s assessment of the evidence.”
Velander v. Garner,
348 F.3d 1359, 1378–79 (Fed. Cir.
2003). Rather, “[o]ur task is to determine whether sub-
stantial evidence supports the conclusion chosen by the
Board.”
Id. Here, we conclude that it does.
Figure 3 of Abe, on its face, discloses a trapezoidal
shape. As the Board described, it shows a quadrilateral
bounded by the lateral faces of light shielding film 9, the
bottom surface of light shielding film 9, and the top surface
of second insulating film 14 within the interior of light
shielding film 9. -958 Decision at 41 (citing Abe ¶¶ 38–39).
The top surface, made of a portion of second insulating film
14, is longer than the bottom surface of light shielding film
9. Abe undisputedly discloses that the lateral faces of the
light shielding film 9 reflect light. See Appeal No. 19-1152
J.A. 937 (Collabo’s expert referring to light shielding film 9
as a “reflector”). Therefore, we hold that substantial evi-
dence supports the Board’s conclusion that Abe discloses “a
vertical cross section of the reflecting wall is a trapezoid
whose upper base is longer than a lower base.”
Case: 19-1152 Document: 68 Page: 14 Filed: 02/25/2020
14 COLLABO INNOVATIONS, INC. v. SONY CORPORATION
None of Collabo’s arguments on appeal demonstrate
that the Board’s conclusion was not supported by substan-
tial evidence. First, Collabo argues that it was “improper
for the Board to conclude ‘that the entire cup shaped struc-
ture, including the material within, is the recited reflecting
wall,” because Sony allegedly “never argued [this] in the
petition.” Appellant’s Br. 51 (quoting -958 Decision at 45).
We disagree. In its petition, Sony presented the annotation
shown above, overlaying a solid brown trapezoid on top of
light shielding film 9 and insulating film 14 as depicted in
Figure 3 of Abe. This annotation could reasonably be
read—indeed, could only credibly be read—as an argument
by Sony that the trapezoidal reflecting wall includes both
the light shielding film and the insulating film inside of it,
as both were shown within the brown trapezoidal annota-
tion. See also Appeal No. 19-1152 J.A. 992 (Sony’s expert
referring to insulating film 14 as the “top of the structure
comprising the reflecting walls” during his deposition).
Thus, we are not persuaded by Collabo’s argument that the
Board “changed the ‘thrust’ of Sony’s unpatentability the-
ory,” Appellant’s Br. 51, when it concluded that the entire
cup shaped structure, including the material within, is the
reflecting wall. 5
5 On appeal, Collabo does not argue that Abe fails to
disclose a trapezoid merely because the trapezoid is made
of two different materials. See Oral Arg. at 9:53–10:01,
available at http://www.cafc.uscourts.gov/oral-argument-
recordings (“We’re not arguing that you can’t have a trape-
zoidal reflecting wall that’s made of multiple materials.
That’s not our argument.”). Such an argument would be
meritless. The Board’s construction of “reflecting walls”
does not preclude a reflecting wall made of multiple mate-
rials. Nor could it, as the ’034 patent itself depicts a re-
flecting wall made of a cup-shaped metal layer filled with
a second material. See ’034 patent at Fig. 5H.
Case: 19-1152 Document: 68 Page: 15 Filed: 02/25/2020
COLLABO INNOVATIONS, INC. v. SONY CORPORATION 15
Collabo further argues that, even assuming insulating
film 14 was part of the reflecting wall in Abe, the resulting
shape is not a trapezoid. Collabo presents numerous pro-
posed annotations, shown below, to demonstrate what it
contends are the shapes of the various structures in Abe.
For example, it presents the following annotation of Abe’s
Figure 3 purporting to show that “‘insulating film 14’ is not
a trapezoid, it is a different shape entirely.”
Appellant’s Br. 52. Collabo presents another annotation of
the same figure, shown below, to alternatively argue that
Abe’s walls are not trapezoids because its “structures have
at least eight edges or sides and vertices or corners.”
Appellant’s Br. 53.
As an initial matter, this argument was not made be-
fore the Board and is therefore waived. See Baxter, 678
F.3d at 1362. Collabo argued to the Board that Abe’s struc-
ture was “simply not a trapezoid.” J.A. 1508–09. But it
made that statement only in the context of its argument
that Abe discloses a “U-shaped design or [a] cup shape.” Id.
at 1509. The two new shapes argued by Collabo in its
Case: 19-1152 Document: 68 Page: 16 Filed: 02/25/2020
16 COLLABO INNOVATIONS, INC. v. SONY CORPORATION
opening brief, which are neither trapezoid nor cup, do not
appear anywhere in the record before the Board, nor does
any corresponding argument.
Even if the argument were not waived, we agree with
Sony that, at least as to the alleged “eight edges” annota-
tion, no evidence supports requiring the level of geometric
perfection that Collabo now advocates. Appellee’s Br. 61.
That is especially true where, as here, both parties’ experts
have conceded that the figures of Abe and the ’034 patent
are rough approximations which do not necessarily reflect
the detailed physical characteristics of the device. See J.A.
934. Further, Collabo’s arguments improperly require us
to perform fact finding. We are not in a position to evaluate
the correctness of Collabo’s new annotations. “It is not our
role to ask whether substantial evidence supports fact-find-
ings not made by the Board, but instead whether such evi-
dence supports the findings that were in fact made.”
Regents of Univ. of Cal. v. Broad Inst., Inc.,
903 F.3d 1286,
1294 (Fed. Cir. 2018).
For the reasons discussed above, substantial evidence,
including Abe’s figures and text, supports the Board’s con-
clusion that Abe discloses “a vertical cross section of the
reflecting wall is a trapezoid whose upper base is longer
than a lower base.” Although Collabo presents an alterna-
tive explanation of the Abe reference, that is insufficient
for reversal under the substantial evidence standard. See
AK Steel Corp. v. U.S.,
192 F.3d 1367, 1371 (Fed. Cir. 1999)
(“[O]ur analysis is not whether we agree with [the agency]’s
conclusions, nor whether we would have come to the same
conclusions reviewing the evidence in the first instance,
but only whether [the agency]’s determinations were rea-
sonable.”).
III
We have considered Collabo’s remaining arguments
and find them unpersuasive. For the foregoing reasons, we
affirm the Board’s construction of “reflecting wall” and its
Case: 19-1152 Document: 68 Page: 17 Filed: 02/25/2020

CLEVENGER, Circuit Judge, dissenting-in-part.
I join Parts I and II.A of the majority’s opinion, but I
respectfully dissent from Part II.B. The majority con-
cludes, as did the Board, that JPA Publication No. H11-
87674 (“Abe”) discloses a “reflecting wall” having a vertical
cross section that “is a trapezoid whose upper base is longer
than a lower base.” According to the majority, the Board’s
finding that Abe satisfies this additional limitation of de-
pendent claims 3 and 12 of
U.S. Patent No. 7,023,034 (the
“’034 patent”) was supported by substantial evidence be-
cause, when drawn together, light shielding film 9 and a
portion of the insulating film 14 form a trapezoid whose
upper base is longer than a lower base. But by blessing the
Board’s analysis, the majority commits the same error.
The question is not whether two structures (or portions
thereof) form a trapezoid when combined, or even whether
Fig. 3 of Abe, on its face, discloses a “trapezoidal shape.”
The appropriate inquiry is whether substantial evidence
supports the Board’s finding that Abe actually discloses
combining multiple, separately-designated, structures
such that their combination forms a trapezoidal “reflecting
wall”—a structure having approximately vertical surfaces
that reflects light? Because Abe does not disclose a trape-
zoidal “reflecting wall,” I respectfully dissent-in-part.

I
Abe’s cup-shaped light shielding film 9, on its own, is a
structure having approximately vertical surfaces that re-
flect light—in other words, it is, on its own, a “reflecting
wall.” It is undisputed that this light shielding film, how-
ever, is not a trapezoid. Thus, in an attempt to conjure up
a trapezoidal “reflecting wall” where one does not other-
wise exist, Sony simply drew a trapezoid onto Fig. 3 of Abe
encompassing both light shielding film 9 and the portion of
the insulating film 14 sitting directly above it.
In its Final Written Decision, the Board relied on
Sony’s annotated version of Fig. 3 of Abe in finding first
that “Figure 3 of Abe shows a ‘pair of reflecting walls’ (i.e.,
a ‘plurality of reflecting walls,’ as claimed),” and second
that “Abe’s description that ‘upper extended portions 92
may be extended so as to incline upwardly from the upper
ends of the lateral faces 9a of the second light shielding film
9’ . . . ‘describe that the vertical cross section of the re-
flecting wall is a trapezoid whose upper base is
longer than a lower base.’” J.A. 47–48 (internal cita-
tions omitted) (bold in original). Thus, the Board held, and
the majority affirms, that Abe discloses the trapezoidal “re-
flecting wall” of claims 3 and 12 of the ’034 patent.
II
In focusing solely on whether Abe discloses a “trapezoi-
dal shape,” Maj. Op. at 13, the majority commits two errors.
First, by focusing on whether Fig. 3 of Abe, on its face, gen-
erally “discloses a trapezoidal shape,”
id., the majority
reads out the requirement that it is specifically the “verti-
cal cross section of the reflecting wall” that must be in the
shape of a trapezoid. J.A. 179 (italics added). Second, the
majority fails to consider whether the Board’s finding that
Abe discloses the “reflecting wall” of claims 3 and 12, which
was not based on the mere existence of a “trapezoidal
shape,” was actually supported by substantial evidence. It
is not. For example, according to Sony, the “Board’s finding

was based on substantial evidence, in the form of Abe’s dis-
closure and Mr. Guidash’s declaration.” Appellee’s Br. at
61 (citing Abe at ¶¶ 44, 46, corresponding to J.A. 458, Abe
at Fig. 3, corresponding to J.A. 462, and Guidash Decl. at
¶341, corresponding to J.A. 381). 1 The cited portions of
both Abe and the Guidash Decl., however, deal solely with
the upwardly inclining portions of light shielding film 9
which, as mentioned above, is a non-trapezoidal “reflecting
wall.” Abe and the Guidash Decl. are entirely silent on a
light shielding film 9 / insulating film 14 combination re-
sulting in a single trapezoidal “reflecting wall.” When
pressed at the oral argument for any actual substantial ev-
idence to support the Board’s finding that Abe discloses a
trapezoidal “reflecting wall” comprising both light shield-
ing film 9 and insulating film 14, counsel for Sony could
only cite to paragraphs 38, 44, 48, and 49 of Abe. See, e.g.,
Oral Arg. at 36:40–37:06; 26:50–37:06, http://oralargu-
ments.cafc.uscourts.gov/default.aspx?fl=2019-1152.mp3.
Again, these paragraphs only disclose the upwardly inclin-
ing portions of light shielding film 9. The mere fact that
the lateral walls of the three-walled light shielding film 9
upwardly incline over the sensor parts 6, however, is not
substantial evidence of a trapezoidal “reflecting wall” com-
prising both light shielding film 9 and insulating film 14.
While the Board and majority are correct that the
claimed “reflecting walls” do not require a uniform compo-
sition, and in fact are not uniform in Fig. 5 of the ’034 pa-
tent, there is no suggestion in Abe that the alleged
combination of light shielding film 9 and portions of, but
not all of, insulating film 14 is, or can be used as, a
1 Sony also argues that Collabo’s expert admitted
that the identified structure is a trapezoid. However, Dr.
Afromowitz appears to have admitted only that the struc-
ture arbitrarily drawn by Sony in its petition, not any “re-
flecting wall” shown in Fig. 3 of Abe, looks like a trapezoid.

“reflecting wall.” 2 Nor does Abe, or Mr. Guidash, 3 explain
why a person of ordinary skill in the art (“POSITA”) at the
time of the invention would find it necessary to arbitrarily
combine the light shielding film 9 with portions of the in-
sulating film 14 so as to form a trapezoidal “reflecting
wall.” Indeed, it appears unlikely that a POSITA would
find such a combination necessary, as light shielding film
9, on its own, allows Abe to derive the same benefits as
those achieved by the ’034 patent’s trapezoidal reflecting
walls. Compare J.A. 457–58, Abe at ¶¶ 38, 44 (disclosing
that “the upper extended portions 92 may be extended so
as to incline upwardly from the upper ends of the lateral
faces 9a of the second light shielding film 9” to more readily
reflect “oblique light” towards the sensors) with J.A. 176,
3:57–60 (“a cross section of the reflecting wall is a trapezoid
whose upper base is longer than the lower base, whereby it
is possible to cause the oblique light to be reflected toward
the aperture more efficiently”).
2 With respect to Fig. 5, the ’034 patent explicitly
states that the combination of Tugsten W film 121 and Ti-
tanium Ti film 122 (which are both reflective and not insu-
lating) make up reflecting wall 62. See J.A. 178, 8:26–33.
In Abe, to the contrary, there is no suggestion or disclosure
of any structure formed through the combination of light
shielding film 9 and insulating film 14.
3 The Guidash declaration merely states that be-
cause the upper extended portions 92 may be extended so
as to incline upwardly, as discussed in Abe ¶ 44, Fig. 3 dis-
closes that the vertical cross section of the reflecting wall
is a trapezoid whose upper base is longer than a lower base.
This is conclusory and belied by the fact that Abe discloses
efficiently reflecting oblique light onto the sensor parts 6
using a three-sided U-shaped light shielding film 9 by it-
self, not a trapezoidal “reflecting wall.”

Even though Sony was unable to point to any substan-
tial evidence supporting the Board’s finding, the majority
finds substantial evidence in the mere existence of a “trap-
ezoidal shape” in Fig. 3 of Abe. As previously discussed,
however, the relevant inquiry is not whether Abe discloses
a “trapezoidal shape,” but whether substantial evidence
supports a finding that Abe discloses a trapezoidal “reflect-
ing wall.” It is clear, on the record before us, that it does
not.
III
For the foregoing reasons, this court should reverse the
Board’s finding of obviousness with respect to claims 3 and
12 of the ’034 patent.
