2 POLYCOM, INC. v. FULLVIEW, INC.
CLEVENGER, Circuit Judge.
Polycom, Inc. appeals a Patent Trial and Appeal Board
(“the Board”) inter partes reexamination decision, which
held claims 1–21 and 25–39 of U.S. Patent No. 6,700,711
(“the ’711 patent”) not obvious under 35 U.S.C. § 103, and
claims 1, 5, 9–15, 25, 29, and 33–39 not anticipated under
35 U.S.C. § 102. Because the Board correctly concluded
that claims 1–21 and 25–39 of the ’711 would not have been
obvious, and because we hold that Polycom waived its an-
ticipation argument, we affirm.
BACKGROUND
I
Cameras have long been capable of capturing an image
that reflects a certain portion of the scene in front of them.
The concept of telepresence, however, has fueled the desire
to capture not just a portion of a scene, but, instead, the
entire scene in which a camera is situated. Telepresence
refers to providing sensory information, especially visual
and audio information, from a given scene and relaying it
back to a person at a remote site. Many businesses use
telepresence, for instance, to enable their employees to at-
tend meetings in remote locations without requiring the
employee to physically travel to that location. In order to
achieve telepresence, one or more cameras must be capable
of capturing multiple views of a given scene, such that a
person can mimic physically being in that scene by switch-
ing between the various views.
The use of more than one camera to capture a scene
naturally creates challenges. Certain aspects of the scene
may go uncaptured because the cameras are arranged at
the remote scene in such a way that there are spaces be-
tween the fields of view they are capable of capturing.
Clearly, a user, such as an employee participating in a re-
mote meeting, would be hindered by the fact that he could
not view the entire meeting scene.
POLYCOM, INC. v. FULLVIEW, INC.
3
In more advanced telepresence systems, the views from
two cameras can be used to simulate a third view from the
points between those cameras, so that a user can view the
entire scene. The third, simulated view is created by “in-
terpolating” between the two actual camera views. ’711 pa-
tent col. 1 ll. 55–60. While interpolation may allow the user
to view the entire scene in which the cameras are situated,
it also creates other problems. Such procedures produce
irregularities in the simulated images due to the different
viewing angles and viewing directions of the actual camera
images. They also require a great amount of computational
power, which in turn drives up the expense and drives
down the efficiency of such systems.
The prior art recognized that one or more mirrors could
be used with one or more cameras to capture the entire
scene, thereby reducing or eliminating the need for inter-
polation. A problem that remained unresolved, however,
was the existence of image artifacts in the resulting com-
posite image caused by “portions of individual images being
captured off edges of mirrors.”
Id. col. 2 ll. 29–30.
In an effort to solve the issues inherent in prior
telepresence systems, the ’711 patent describes using mir-
rors and multiple cameras to capture images of a scene and
then merging those images to produce a composite, pano-
ramic image that eliminates “at least a portion of a cam-
era’s field of view.”
Id. Abstract.
In one embodiment of the invention, the cameras are
positioned around a polyhedron where each face of the pol-
yhedron has a reflective surface. The cameras each view a
different reflective face of the polyhedron as shown in Fig-
ure 2 below.
4 POLYCOM, INC. v. FULLVIEW, INC.
Cameras 52, 54, 56, and 58 are associated with reflec-
tive sides 48, 42, 44, and 46, respectively. The cameras all
share a virtual optical center 90—the position from which
the camera’s field of view appears to originate—within the
pyramid. The field of view of each camera—the reflection
it views off of the reflective surface of the polyhedron—is
merged with the individual fields of view of the other cam-
eras and arranged to form a composite field of view, which
is a continuous 360-degree view of an area when taken as
a whole.
In another embodiment of the invention, the cameras
are positioned around the pyramid “so that their effective
optical centers are offset from each other. The offsets pro-
duce narrow blind regions that remove image distortions
received from the edges of the pyramid’s reflective surface.”
Id. col. 3 ll. 12–15.
Figure 14, which depicts the additional embodiment, is
a top view of the pyramid arrangement shown in Figure 2.
In reference to Figure 2, cameras 52, 54, 56, and 58 have
been moved upward in the direction of base 50. As a result,
virtual optical centers 500, 502, 504, and 506, which corre-
spond to cameras 52, 54, 56, and 58, respectively, are
moved away from virtual optical center 90. According to
POLYCOM, INC. v. FULLVIEW, INC.
5
the invention, it is desirable to move the cameras away
from optical center 90 because then they do not capture im-
ages from the narrow planar shaped regions, 524, 526, 528,
and 530, also called “blind regions,” which include image
artifacts created by the edges of the reflective polyhedron.
Eliminating those regions from the cameras’ fields of view
alleviates the need for image processing, and, therefore, ex-
tensive computational power. The specification notes that
“it is desirable to keep virtual optical centers 500, 502, 504,
and 506 closely clustered so that planes 524, 526, 528, and
530 are only as thin as necessary to avoid edge artifacts”
while minimizing any noticeable effect seen by the user.
Id. col. 9 ll. 61-64.
The ’711 patent claims both a method and an appa-
ratus. Claim 1 is illustrative of the claimed method and
Claim 16 is illustrative of the claimed apparatus:
1. A method of producing a composite image with a
plurality of sensors each having an individual field
of view, comprising the steps of:
for at least one of the plurality of sensors,
redirecting at least a portion of its individ-
ual field of view with a reflective area; and
6 POLYCOM, INC. v. FULLVIEW, INC.
merging images corresponding to the indi-
vidual fields of view to produce the compo-
site image having a corresponding field of
view, wherein each one of at least two fields
of view corresponding to images that are
merged has a portion, where the images are
merged, that has viewing directions that
are substantially similar to the viewing di-
rections of the other portion, and wherein
the viewing directions within each one of
such two portions appear to originate sub-
stantially from a point that is offset from
the point for the other one of such two por-
tions.
16. A viewing apparatus having a composite field
of view, comprising:
at least two image sensors, each having an
individual field of view;
at least one reflective area that redirects at
least part of the individual field of view as-
sociated with one of the image sensors,
the individual fields of view of at least two
image sensors being merged to produce the
composite field of view, at least portions of
each of the two individual merged fields of
view having substantially similar viewing
directions where they are merged, and the
merged fields of view creating in the com-
posite field of view at least one blind region
that encompasses at least a portion of an
edge of the reflective area and that lies be-
tween portions of two individual fields of
view; and
a memory for storing data representative of
said composite field of view electronically.

The relevant prior art references disclose improve-
ments in image processing. One piece of prior art, an arti-
cle entitled “Seamless Image-Connection Technique for a
Multiple-Sensor Camera” (“Uehira”), describes a refine-
ment to prior methods of improving HDTV picture resolu-
tion. Kazutake Uehira & Kazumi Komiya, Seamless
Image-Connection Technique for a Multiple-Sensor Cam-
era, E77-B IEICE Trans. Comm. 232 (1994). The prior art
methods utilized multiple two-dimensional charge-coupled
device (“CCD”) sensors arrayed in a focal plane. Though
the prior method reduced the cost of a high-resolution cam-
era, it was not easy to join the images from the separate
CCD sensors without losing part of the image in the pro-
cess. The authors of Uehira solved that problem by using
a pyramidal mirror to produce four separate focal planes
that “prevent gaps along the joining lines of the combined
image,” as shown below in Figure 4.
Id. at 232. “Each CCD
sensor reads a quarter of the image and the four quarter-
images are combined in to one HDTV picture.”
Id. The au-
thors demonstrated that they could reduce image disconti-
nuity at the joining lines and eliminate shading caused by
the pyramidal mirror by using certain image-processing
techniques, such as electrical correction and dark-and
white-level correction.
8 POLYCOM, INC. v. FULLVIEW, INC.
Another piece of prior art, U.S. Patent No. 5,444,478,
entitled “Image Processing Method and Device for Con-
structing an Image from Adjacent Images” (“Lelong”), dis-
closes a method of processing images to construct a target
image from adjacent source images where the source and
the target images have “substantially common view
points.” Lelong Abstract. Lelong, like the ’711 patent,
sought to improve the concept of telepresence, or as Lelong
refers to it, “telemonitoring.”
Id. col. 1 ll. 28–31. Lelong
wanted to create a device that could provide views to a user
at a remote location that simulated the views seen by a sta-
tionary observer present at another location. For example,
Lelong wanted a remote user to be able to see to the left
and right, as well as above and below, an imaginary sta-
tionary observer at the scene.
To achieve that goal, Lelong’s system requires that the
combined fields of view of each camera capture all of the
details of the scene “so that no object under surveillance is
left out.”
Id. col. 6 ll. 37–38. To ensure that no aspects of
a scene are left uncaptured, the cameras in Lelong are “ar-
ranged in such a way that their optical centers P, referred
to as view points[,] coincide,”
id. col. 6 ll. 64–66, or are “very
close” to coinciding, as shown in Figure 1G.
Id. col. 6 l. 39.
Unlike the system disclosed in the ’711 patent, Lelong’s
system does not use a mirror.
POLYCOM, INC. v. FULLVIEW, INC.
9
The cameras in Figure 1G, though not shown, are clus-
tered around P, which denotes the “view point” or “optical
center” of the cameras.
Id. col. 6 ll. 65–66. Lelong explains
that, in certain circumstances, the view points of the cam-
eras need not be the same, i.e., “coincide physically.”
Id.
col. 7 ll. 3–4. The patent assumes, however, that “the con-
dition of coincidence is fulfilled sufficiently if the distance
separating each of these view points is small as regards
[sic] their distance to the filmed panoramic scene.”
Id. col 7
ll. 5–8. Stated another way, Lelong assumes that the con-
dition of coincidence is fulfilled when the ratio between the
distance to the panoramic scene and the distance separat-
ing the view points is equal to or greater than fifty. When
the ratio is equal to or greater than fifty, Lelong explains
that “it is not necessary to use costly optical mirror systems
which are difficult to adjust for achieving a strict coinci-
dence of the view points.”
Id. col. 7 ll. 13–15.
III
On January 26, 2012, Polycom filed a request for reex-
amination of the ’711 patent. The Examiner granted Poly-
com’s request in part, finding that it demonstrated a
reasonable likelihood of prevailing on anticipation of
claims 1–8, 12–21, 25–32, and 36–39 by Lelong and on ob-
viousness of claims 1–5, 9–18, 25–29, 38, and 33–39 over
Uehira. Obviousness over the combination of Lelong and
Uehira was asserted as a ground for reexamination in Pol-
ycom’s request, but the Examiner determined that “the re-
quest and claim charts . . . d[id] not make clear the
limitations Lelong is lacking and the limitations for which
Uehira is cited or how Lelong is modified by Uehira.” J.A.
264. Thus, the Examiner declined to institute reexamina-
tion on that ground. In sum, the Examiner instituted reex-
amination of claims 1–21 and 25–39, but declined to
institute reexamination with respect to claims 22–24 of the
’711 patent.
10 POLYCOM, INC. v. FULLVIEW, INC.
On March 14, 2012, the Examiner issued a non-final
office action rejecting claims 1–8, 12–21, 25–32, and 36–39
as anticipated by Lelong. The Examiner also rejected
claims 1–5, 9–18, 25–29, 38, and 33–39 as anticipated by
Uehira. 1
Polycom petitioned for review of the partial denial of
its reexamination request. The Director denied Polycom’s
petition.
The Examiner later withdrew the anticipation rejec-
tion based on Lelong, however, because Lelong “[did] not
expressly or inherently describe ‘at least one reflective area
for redirecting at least a portion of the field of view associ-
ated with one of the image sensors.’” J.A. 516. The Exam-
iner also noted that Lelong “did not make obvious
‘redirecting at least a portion of its individual field of view
with a reflective area’” because Lelong disclosed that opti-
cal mirrors were costly and difficult to use, and therefore
taught away from the use of such mirrors.
Id.
In the Action Closing Prosecution, the Examiner re-
jected claims 1, 5, 9–15, 25, 29, and 33–39 as anticipated
by Uehira. The Examiner confirmed the patentability of
claims 2–4, 6–8, 16–21, 26–28, and 30–32 by withdrawing
the anticipation and obviousness rejections under Lelong
and the anticipation rejection under Uehira. Polycom ap-
pealed the Examiner’s decision not to reject claims 1–8, 12–
21, 25–32, and 36–39 as anticipated by or obvious over
Lelong. Fullview appealed the Examiner’s rejection of
claims 1, 5, 9–15, 25, 29, and 33–39 as anticipated by
Uehira.
1 The Examiner did not reconcile its rejection for an-
ticipation by Uehira with the fact that the Examiner had
granted Polycom’s request for reexamination on the basis
that Uehira rendered obvious claims 1–5, 9–18, 25–29, 38,
and 33–39.
POLYCOM, INC. v. FULLVIEW, INC.
11
In the Board’s Decision on Appeal, it reversed the Ex-
aminer’s rejection of claims 1, 5, 9–15, 25, 29, and 33–39 as
anticipated by Uehira because it found that Uehira did not
describe the following limitation: “wherein the viewing di-
rections within each one of such two portions appear to
originate substantially from a point that is offset from the
point for the other one of such two portions.” Polycom , Inc.
v. Fullview, Inc., Appeal No. 2014-3318,
2014 WL 4923553,
at *4 (P.T.A.B. Sept. 29, 2014) (“Board Decision”). The
Board also found that the Examiner erred in concluding
that Lelong did not teach or suggest mirrors and that
Lelong teaches away from the redirecting limitation of
claim 1.
The Board then went on to reject claims 1–39 as obvi-
ous over the combination of Lelong and Uehira, a ground
on which the Examiner refused to institute. Notably, the
Board found that it was obvious to “employ Uehira’s mir-
rors in Lelong’s system to ‘redirect[] at least a portion of [a
sensor’s] individual field of view with a reflective area’ as
recited in claim 1.”
Id. at *7.
The Board also found that a person of ordinary skill in
the art (“POSA”) would have known to arrange the optical
elements taught by Lelong and Uehira “such that two sen-
sors having substantially similar viewing directions pro-
duce images that appear to originate from offset view
points by placing them at different distances from a reflec-
tive surface that redirects their individual fields of view to-
ward the same scene.”
Id. The Board thus found claim 1
invalid over Lelong and Uehira.
The Board also found claim 2 obvious over the two ref-
erences because Uehira disclosed “gaps along the joining
lines of the combined image” that could be “prevented”
when an image focused at the focal plane is wider than the
corresponding area of an object.
Id. at *3 (citing
Uehira,
supra, at 233). Additionally, Lelong disclosed “arranging
sensors such that view points are not strictly coincident,
12 POLYCOM, INC. v. FULLVIEW, INC.
which one skilled in the art would realize creates gaps or
overlaps.”
Id. at *8. Thus, the Board found claim 2 satisfied
because the references disclosed “at least one blind region
that encompasses at least a portion of an edge of a reflec-
tive area and that lies between the two portions of the two
individual fields of view.”
Id.
Because the rest of the claims recited either varying
the numbers of sensors or electronically merging and stor-
ing data, the Board found those claims were also obvious
variations in view of Lelong and Uehira. The Board there-
fore entered that new ground of rejection and, under 37
C.F.R. § 41.77(b) (2004), provided Fullview with the option
of reopening prosecution or requesting rehearing.
In response to the Board’s decision, Fullview filed a re-
quest to reopen prosecution and presented new evidence in
the form of two declarations: one of Arun Netravali
(“Netravali Declaration”) and one of Vishvjit S. Nalwa
(“Nalwa Declaration”). Polycom filed comments responsive
to Fullview’s request and presented new evidence in the
form of a declaration of Stephen D. Fantone (“Fantone Dec-
laration”). After receiving the parties’ submissions, the
Board then remanded the proceeding to the Examiner to
issue a determination that each rejection should be main-
tained or overcome by the new evidence.
The Examiner determined that the response by
Fullview, along with the Netravali Declaration, overcame
the new grounds of rejection by the Board. The Examiner
found that it would not have been obvious to employ
Uehira’s mirrors in Lelong’s system to redirect at least a
portion of a sensor’s individual field of view with a reflec-
tive area because, as the Netravali Declaration explained,
“it is counterintuitive why anyone would use mirrors to
make the viewpoints of multiple sensors coincide (as in
Uehira) only to turn around and deliberately offset the
viewpoints.” J.A. 764. The Examiner also determined that
“moving the sensors or mirrors of Uehira does not change
POLYCOM, INC. v. FULLVIEW, INC.
13
the sensor’s viewpoints precisely because the ‘field of view’
of each sensor is in front of its image-forming lens, where
it is out of reach of the mirrors of Uehira.” J.A. 765.
The Examiner found that the combination of Lelong
and Uehira also did not disclose the type of blind regions
required by the ’711 patent’s claims because any blind re-
gions in Uehira would be “wedge-shaped, each such wedge
expanding from the common viewpoint shared by multiple
CCD sensor[s], with the viewing directions on either side
of such ‘blind regions’ not being substantially similar.”
J.A. 766. The Examiner also noted that Polycom never ad-
dressed how any alleged blind regions disclosed by Lelong
“encompass a portion of an edge of a reflective area, as re-
quired by the claims.”
Id.
Following the Examiner’s determination during the re-
opened prosecution, Fullview and Polycom filed responsive
comments. The proceeding was then returned to the Board
to reconsider the matter and issue a new decision. The
Board affirmed the Examiner’s non-adoption of the rejec-
tion of claims 1–39 as obvious over the combination of
Lelong and Uehira. The Board noted that it was persuaded
by the Netravali Declaration that Polycom failed to demon-
strate “that Lelong (or Uehira) discloses or suggests the
‘viewing directions’ or ‘portions’ of at least two fields of view
as recited in claim 1.” J.A. 27. According to the Board,
Polycom did not explain how the “view points” of Lelong
both could be “substantially similar” yet “substantially . . .
offset” from each other at the same time. J.A. 28.
Fullview then requested a rehearing of the Board’s de-
cision, arguing the Board abused its discretion by consider-
ing obviousness over Lelong and Uehira, and that the
Board applied the wrong claim construction standard to an
expired patent. Polycom also requested rehearing, claim-
ing the Board’s non-obviousness determination was not
supported by substantial evidence. Polycom did not re-
quest rehearing of the Board’s failure to find claims 1–8,
14 POLYCOM, INC. v. FULLVIEW, INC.
12–21, 25–32, and 36–39 anticipated over Lelong, despite
the Board’s holding that the Examiner erred in concluding
the Lelong taught away from the use of mirrors.
First, the Board withdrew its rejection of claims 22–24
because, as both Fullview and Polycom argued, the Board
did not have the authority to consider those claims as they
were never subject to reexamination. The Board then con-
sidered and rejected Fullview’s argument that the Board
abused its discretion in entering a new ground of rejection.
The Board also denied Polycom’s request for a rehearing of
the Board’s decision to affirm the Examiner’s non-adoption
of the rejection of claims 1–21 and 25-39.
Polycom appeals from the Board’s decision on rehear-
ing. We have jurisdiction to consider Polycom’s appeal un-
der 28 U.S.C. § 1295(a)(4)(A).
DISCUSSION
Polycom argues that the alleged inconsistencies in the
Board’s original decision, its decision after reopening pros-
ecution, and its decision on rehearing warrant reversal.
First, Polycom contends that the Board should have found
the challenged claims of the ’711 patent anticipated by
Lelong after determining during the first Board hearing
that, contrary to the Examiner’s finding, Lelong disclosed
mirrors. According to Polycom, the Examiner withdrew
her anticipatory rejection because Lelong taught away
from mirrors, and thus, the Board’s finding that Lelong did
not, in fact, teach away from mirrors should have ended the
Board’s analysis. Second, Polycom claims that the Board
inextricably adopted a different reading of the ’711 patent’s
claims and Lelong’s disclosure than was laid out in its orig-
inal decision to erroneously affirm the Examiner’s nonob-
viousness determination.
The ultimate determination of obviousness is a ques-
tion of law, but that determination is based on underlying
factual findings. See In re Gartside,
203 F.3d 1305, 1316
POLYCOM, INC. v. FULLVIEW, INC.
15
(Fed. Cir. 2000). We review the Board’s legal determina-
tions de novo and any underlying factual determinations
for substantial evidence. In re Baxter Int’l, Inc.,
678 F.3d
1357, 1361 (Fed. Cir. 2012). Anticipation, on the other
hand, is strictly a question of fact subject to substantial ev-
idence review. Microsoft Corp. v. Biscotti, Inc.,
878 F.3d
1052, 1068 (Fed. Cir. 2017).
I
Fullview contends that we need not address Polycom’s
anticipation argument because it was waived below. Ac-
cording to Fullview, Polycom should have included its an-
ticipation argument in its request for rehearing, and,
because it failed to do so, it cannot resurrect that argument
now on appeal. We agree with Fullview.
Polycom argues that it is not required to first request
rehearing before challenging a Board decision on appeal.
To support its argument, Polycom cites a case which held
that “[n]owhere does the statute granting parties the right
to appeal a final written decision in an [inter partes review
(‘IPR’)] require that the party first file a request for rehear-
ing before the Board, especially a rehearing of the initial
institution decision.” In re Magnum Oil Tools Int’l, Ltd.,
829 F.3d 1364, 1377 (Fed. Cir. 2016). But that precedent
does nothing to save Polycom’s argument from waiver here.
In Magnum, the Patent and Trademark Office argued
that the appellant had to raise its concerns to the Board in
a request for rehearing of the initial institution decision,
but we found that the appellant’s issue was not with the
Board’s decision to institute the IPR on some grounds in-
stead of others.
Id. at 1373. Its issue, instead, was with
certain statements that the Board made in that institution
decision regarding the obviousness of the claimed inven-
tion which were later relied upon in the Board’s final writ-
ten decision.
Id. at 1373-74. We thus found that, because
those determinations were incorporated into the final writ-
ten decision, which is directly appealable to this court, the
16 POLYCOM, INC. v. FULLVIEW, INC.
appellant did not need to make arguments regarding those
statements in a request for rehearing of the institution de-
cision.
Id. at 1377.
Here, while Polycom could have directly appealed the
Board’s reopen decision to this Court, it instead decided to
request rehearing of that decision. Because it made that
strategic decision, it was required to include all of the
“points believed to have been misapprehended or over-
looked in rendering the Board’s opinion reflecting its deci-
sion.” 37 C.F.R. § 41.79 (2004). While it is true that the
Board’s reopen decision did not address arguments regard-
ing anticipation over Lelong, the reopen decision “is
deemed to incorporate the earlier decision[s], except for
those portions specifically withdrawn.” 37 C.F.R. § 41.77.
The Board’s original decision addressed the Examiner’s de-
cision to withdraw her anticipation rejection over Lelong.
That aspect of the Board’s original decision was never with-
drawn. Thus, Polycom could have, and should have, raised
the anticipation argument in its request for rehearing be-
cause this court should not be put in the position of review-
ing an alleged error in the Board’s reasoning that the
Board itself was not given a chance to address when it con-
sidered Polycom’s other arguments on rehearing. See In re
NuVasive, Inc.,
842 F.3d 1376, 1380 (Fed. Cir. 2016) (ex-
plaining that such a course of action “deprives the court of
‘the benefit of the [Board]’s informed judgment’” (citation
omitted)). For those reasons, we find that Polycom waived
its arguments regarding anticipation of the ’711 patent
over Lelong.
II
Polycom also challenges the Board’s nonobviousness
determination. First, Polycom contends that the Board
misread claim 1 to require a substantial offset between the
cameras. Second, Polycom argues that the Board incor-
rectly interpreted Lelong to teach that mirrors are not used
when the offset is small. Third, Polycom claims that the
POLYCOM, INC. v. FULLVIEW, INC.
17
Board erred in its determination that, if Lelong taught a
large offset, then the viewing directions would not be “sub-
stantially similar,” as required by claim 1. Fourth, Poly-
com argues that the Board’s incorrect reading of claim 1 to
require a substantial offset also led to error in the Board’s
analysis of a POSA’s motivation to combine Lelong and
Uehira.
Polycom’s first argument fails because, even if the
Board incorrectly interpreted claim 1 to require that the
offset between the points be substantial in its decision after
the reopened prosecution, it rectified that error in its deci-
sion on rehearing. The Board assumed that the claimed
offset was not substantial, and found that “Lelong explic-
itly disclose[d] that when the ‘offset’ of the ‘view points’ . . .
is not substantial, then ‘costly optical mirror systems’ (or
reflective areas) are not used.” J.A. 10.
To counter the Board’s determination, Polycom argues
on appeal that the Board’s rehearing decision inexplicably
contradicts the Board’s prior analysis of Lelong in its orig-
inal decision. According to Polycom, the Board previously
determined that Lelong did not teach away from the use of
mirrors, but instead indicated that mirrors may not be nec-
essary in certain situations.
Polycom mischaracterizes the Board’s original deci-
sion. The Board disagreed with the Examiner that Lelong
taught away from the claimed invention, “at least for ap-
plications where the distance to the filmed scene is rela-
tively small,” relative to the distance between the view
points. Polycom,
2014 WL 4923553, at *5 (emphasis
added). The Board also recognized, however, that “Lelong
purport[ed] to render mirrors unnecessary in situations
where ‘the distance separating each of these view points is
small as regards [sic] their distance to the filmed pano-
ramic scene.’”
Id. (emphasis added). The Board did not
comment definitively on whether Lelong taught away from
the use of mirrors when the distance separating the view
18 POLYCOM, INC. v. FULLVIEW, INC.
points was small as compared to their distance to the pan-
oramic scene. See
id. (“[W]ithout regard to whether
Lelong’s statement ‘criticizes, discredits, or otherwise dis-
courages’ the use of mirrors in all contexts.”).
Polycom’s second argument is also unpersuasive be-
cause the Board’s determination that Lelong does not teach
the use of mirrors when the offset is small is supported by
substantial evidence. First, despite Polycom’s arguments
to the contrary, the Board did not improperly read Lelong
to be limited to a small offset in absolute terms. The Board
noted “that Lelong . . . discloses that when the offset is not
substantial (e.g., “ 5cm or 10 cm [when] the distance to the
panoramic scene is 5 m”), then ‘costly optical mirror sys-
tems’ are not used.” J.A. 10. The Board thus clearly recog-
nized that the offset’s size was relative—not absolute—to
the distance to the panoramic scene.
Moreover, as the Board’s quoted language indicates,
Lelong does, in fact, state that “it is not necessary to use
costly optical mirror systems which are difficult to adjust
for achieving a strict coincidence of the viewpoints” when
the offset distance is small relative to the cameras’ distance
to the panoramic scene. Lelong col. 7 ll. 13–15. The Board
found that Polycom did not explain why it would have been
obvious to a POSA to incorporate a reflective area into
Lelong despite that disclosure. Polycom’s attempt to offer
that missing explanation through its expert’s declaration
is unavailing.
On appeal, Polycom cites to Dr. Fantone’s declaration
for the proposition that, when the scene being captured is
about two meters away, a POSA would understand that an
optical mirror system could be used in Lelong’s invention.
The Board, however, clearly credited Fullview’s expert’s
declaration, as opposed to the Fantone Declaration. See
J.A. 26-27 (citing the Netravali Declaration as persuasive
“that [Polycom] has not demonstrated sufficiently that
Lelong (or Uehira) discloses or suggests the ‘viewing
POLYCOM, INC. v. FULLVIEW, INC.
19
directions’ of ‘portions’ of at least two fields of view as re-
cited in claim 1”). “The Board has broad discretion as to
the weight to give to declarations offered in the course of
prosecution.” In re Am. Acad. of Sci. Tech Ctr.,
367 F.3d
1359, 1368 (Fed. Cir. 2004). Polycom does not present any
persuasive evidence for why the Board abused its discre-
tion in crediting the Netravali Declaration over the Fan-
tone Declaration. Moreover, Dr. Fantone never explained
how the “substantially similar” “viewing directions” from
“offset” “points” limitation would be satisfied in the situa-
tion where a mirror system is used to capture a panoramic
scene two meters away from the cameras. Thus, the Board
did not abuse its discretion.
Polycom’s third argument focuses on the Board’s al-
leged error in finding that the viewing directions would not
be substantially similar, as required by claim 1, if Lelong
disclosed a large offset between the view points. Polycom
claims that Figure 1G of Lelong is essentially the same as
Figure 14 in the ’711 patent. According to Polycom, Figure
14 demonstrates that, for example, “if the viewing direc-
tions are both pointing northeast when the offset (gap) is
small, they are still pointing northeast (i.e., the same di-
rection) when the offset (gap) is large.” Appellant’s Op. Br.
34. While the Board did not specifically address Polycom’s
argument in its decisions, that omission does not constitute
reversible error. See Yeda Research v. Mylan Pharm. Inc.,
906 F.3d 1031, 1046 (Fed. Cir. 2018) (“[F]ailure to explicitly
discuss every fleeting reference or minor argument does
not alone establish that the Board did not consider it.”).
Polycom cites no support for its argument, and, as Pol-
ycom admits, Figure 1G does not include the use of mirrors.
Additionally, Fullview’s expert’s declaration, which the
Board credited in its decision after the reopened prosecu-
tion, contradicted Polycom’s unsupported attorney argu-
ment. See J.A. 716 (“[O]ffset (rather than coincident)
viewpoints result in dissimilar viewing directions to any
object and yet, according to the patent, viewing directions
20 POLYCOM, INC. v. FULLVIEW, INC.
from different view-points are substantially similar where
the images are merged.”); see also Icon Health & Fitness,
Inc. v. Strava, Inc.,
849 F.3d 1034, 1043 (Fed. Cir. 2017)
(“Attorney argument is not evidence.”).
As for Polycom’s fourth argument, it contends that
Lelong does not characterize the offset between view points
in absolute terms. Polycom therefore claims that the Board
was wrong to limit Lelong’s teaching to a small or a large
offset distance. Because Lelong’s teaching is not so limited,
and because the claims require only an offset, Polycom con-
tends that Lelong’s teaching, in combination with Uehira’s
mirrors, should have been enough to render the ’711 pa-
tent’s claims obvious. Polycom’s argument is not persua-
sive.
The Board read claim 1 to recite:
[A] ‘viewing direction of one portion of an image
that is ‘substantially similar’ to a ‘viewing direc-
tion’ of a portion of another image and that the
‘viewing direction of the one portion appears to
‘originate’ from a ‘point’ that is offset from the
‘point’ from which the other ‘viewing direction’ (of
the portion of the other image) appears to origi-
nate.
J.A. 9. Polycom argued below that Lelong discloses cam-
eras arranged in such a way that “their optical centers P,
referred to as view points[,] coincide.” J.A. 147. Polycom
therefore claimed that Lelong discloses substantially simi-
lar viewing directions, as required by claim 1 of the ’711
patent, because if the view points coincided then the view-
ing directions from those points must be substantially sim-
ilar. Polycom also argued that Lelong’s cameras, and thus
its view points, need not coincide physically, and, instead,
can be separated or offset from each other. Based on that
argument, Polycom contended that the offsets claimed by
the ’711 patent were also disclosed in Lelong. As the Board
recognized, those positions are clearly contradictory.
POLYCOM, INC. v. FULLVIEW, INC.
21
Missing from Polycom’s evidence or arguments was an ex-
planation of how the viewing directions of Lelong’s cameras
could be substantially similar, while simultaneously ap-
pearing to originate from points that are offset from each
other.
Moreover, Fullview’s expert’s declaration, which the
Board credited, explained the counterintuitive nature of
“us[ing] mirrors to make the viewpoints of multiple sensors
coincide . . . only to turn around and deliberately offset the
viewpoints,” such that the offset is perceptible to the
viewer. J.A. 716. Lelong discloses the use of mirrors, as an
alternative to its claimed non-mirrored optical system, to
achieve “strict coincidence of view points,” Lelong col. 7 l.
15, in situations where the “condition of coincidence” is not
satisfied because the distance between the view points is
large relative to the distance to the panoramic scene.
Id.
col. 7 l. 5. Polycom therefore failed to counter Fullview’s
evidence in two respects. Polycom did not show that a
POSA would be motivated to use Uehira’s mirror’s in
Lelong’s optical system with insubstantial offsets. It also
failed to show that a POSA would be motivated to use the
mirrored optical system discussed in Lelong to arrive at the
claimed invention, which requires the use of a mirror to
achieve “substantially similar” viewing directions that ap-
pear to originate from offset, not coincident, view points.
We thus affirm the Board’s ultimate determination that
neither Lelong nor Uehira disclosed or suggested “the
claimed ‘viewing directions’ of ‘portions’ of fields of view or
the substantial similarity or offsets of points of apparent
origination of such viewing directions.” J.A. 29.
III
Last, Fullview raises an argument in its opposition
brief alleging that the Board abused its discretion in enter-
ing a new ground of rejection based on obviousness over
Lelong and Uehira. At oral argument, however, Fullview
made clear that argument was meant only as one in the
22 POLYCOM, INC. v. FULLVIEW, INC.
alternative if this court decided not to affirm the Board’s
nonobviousness finding. Oral Arg. at 25:54–26:21.
Fullview further agreed to withdraw that argument if this
court affirmed the Board’s nonobviousness findings.
Id.
Because we affirm the Board on that ground, we need not
reach Fullview’s new-ground-of-rejection argument.
CONCLUSION
After careful analysis of the parties’ arguments and the
Board’s determination, we affirm the Board’s finding that
claims 1–21 and 25–39 of the ’711 patent would not have
been obvious in view of the combination of Lelong and
Uehira. We also find that Polycom waived its argument
regarding anticipation for failing to raise it below.
