                  ______________________

    Before NEWMAN, TARANTO, and STOLL, Circuit Judges.
STOLL, Circuit Judge.
     Emerson Electric Co. challenged various claims of
SIPCO, LLC’s U.S. Patent No. 8,013,732 in an inter
partes review. The U.S. Patent and Trademark Office’s
Patent Trial and Appeal Board determined that Emerson
failed to show that certain claims would have been un-
patentable as obvious. Because the Board did not ade-
quately explain its reasoning on a point that was central
to its analysis and its conclusion on that point was con-
trary to another Board opinion on nearly identical facts,
we vacate the Board’s determination as to the appealed
claims and remand for further proceedings.
                              I
                             A
    SIPCO’s ’732 patent is titled “Systems and Methods
for Monitoring and Controlling Remote Devices.” It
describes and claims systems and methods for “monitor-
ing a variety of environmental and/or other conditions
within a defined remotely located region,” such as utility
meters in a specific area. ’732 patent, Abstract.
     The patent effectively takes a prior art wired sensor
network and converts it to a wireless network. Compare
id. Fig. 1, with id. Fig. 2, and col. 4 ll. 42–43, and col. 7
ll. 33–56. Independent claim 13 is illustrative of the
invention, which is directed to a system for wirelessly
monitoring conditions in a defined region:
    13. In a system comprising a plurality of wireless
    devices configured for remote wireless communi-
    cation and comprising a device for monitoring and
    controlling remote devices, the device comprising:
EMERSON ELECTRIC CO.   v. SIPCO, LLC                       3

    a transceiver having a unique identification code
    and being electrically interfaced with a sensor, the
    transceiver being configured to receive select in-
    formation and identification information trans-
    mitted from another wireless transceiver in a
    predetermined signal type;
    the transceiver being further configured to wire-
    lessly retransmit in the predetermined signal type
    the select information, the identification infor-
    mation associated with the nearby wireless trans-
    ceiver, and transceiver identification information
    associated with the transceiver making retrans-
    mission; and
    a data controller operatively coupled to the trans-
    ceiver and the sensor, the data controller config-
    ured to control the transceiver and receive data
    from the sensor, the data controller configured to
    format a data packet for transmission via the
    transceiver, the data packet comprising data rep-
    resentative of data sensed with the sensor.
Id. at claim 13.
                              B
    In September 2015, Emerson petitioned for inter
partes review of claims 13, 14, 16–21, and 23–35 as obvi-
ous under 35 U.S.C. § 103. Each ground Emerson articu-
lated included Kahn1 in view of the Admitted Prior Art. 2

    1   Robert E. Kahn et al., Advances in Packet Radio
Technology, 66 Proceedings of the IEEE 1468 (1978)
(Ex. 1002) (“Kahn”), J.A. 376–404.
    2   Petitioner defined the “Admitted Prior Art” as the
disclosures found in the ’732 patent at column 1, lines 54
through 65; column 2, lines 27 through 29; column 5,
lines 32 through 44; and Figure 1. Emerson Elec. Co. v.
4                        EMERSON ELECTRIC CO.   v. SIPCO, LLC

Kahn discloses a wireless packet radio network. Kahn
at 1468 col. 1, J.A. 376. Indeed, Kahn explained that one
capability of the packet radio network was rapid and
convenient deployment. Kahn at 1470, J.A. 378. The
Admitted Prior Art discloses monitoring and control
systems, including sensor actuators electrically coupled to
a local controller. See ’732 patent, col. 5 ll. 32–37. Emer-
son, in its petition, relied on Kahn for the motivation to
use the wireless packet radio of Kahn as a communication
network for the prior art monitoring and control systems
described in the Admitted Prior Art. Petition Requesting
Inter Partes Review, Emerson Elec. Co. v. SIPCO, LLC,
IPR2016-01973, Paper 2 at 14 (P.T.A.B. Sept. 25, 2015)
(“Petition”), J.A. 82. Specifically, Emerson argued that a
skilled artisan:
    would have recognized the advantage of using the
    communication infrastructure disclosed in Kahn
    to allow the sensors and actuators of the [Admit-
    ted Prior Art] to be moved from location to loca-
    tion without having to re-install physical cables
    and wires to connect the sensors and actuators.
Id. In March 2016, the Board instituted inter partes
review based on all of the grounds in Emerson’s petition. 3
    At the oral hearing, Emerson for the first time re-
ferred to an article by Bill Greeves, SCADA Uses Radio to
Bridge the Gap, 14 Sensor Review, no. 2, 1994, at 31
(“Greeves”), J.A. 1368–72, to support its argument regard-

SIPCO, LLC, No. IPR2015-01973, Paper 25 at 2 n.2
(P.T.A.B. Mar. 27, 2017) (“Final Written Decision”).
    3   Because the Board issued a Final Written Deci-
sion addressing all the claims that Emerson challenged,
this case is not impacted by the Supreme Court’s recent
decision in SAS Institute Inc. v. Iancu, 138 S. Ct. 1348
(2018).
EMERSON ELECTRIC CO.   v. SIPCO, LLC                    5

ing motivation to combine. Emerson relied on Greeves to
show that a person of ordinary skill in the art would have
been motivated to combine Kahn and the Admitted Prior
Art, noting that Kahn itself affirmed that the need for
cost reduction described in the Admitted Prior Art was a
known problem. The Board, however, determined that it
would be improper for it to rely on Greeves as evidence of
motivation to combine because Emerson did not rely on it
until oral argument. It was SIPCO’s declarant who
introduced Greeves into the record for the purpose of
showing challenges with radio technology. Emerson did
not even mention Greeves in its briefing or its expert
declaration. Accordingly, the Board focused its analysis
only on Kahn and the Admitted Prior Art.
    The Board, in its Final Written Decision, concluded
that it was “not persuaded that Kahn provides a ra-
tionale, separate and apart from hindsight, which would
motivate one of ordinary skill in the art to combine the
teachings of Kahn and the [Admitted Prior Art].” Final
Written Decision at 12. Accordingly, the Board held that
Emerson had not proven by a preponderance of the evi-
dence that the challenged claims of the ’732 patent were
unpatentable. Emerson timely appeals. We have juris-
diction under 28 U.S.C. § 1295(a)(4)(A).
                              II
    Emerson raises two main issues on appeal:
(1) whether the Board erred by not considering Greeves;
and (2) whether the Board erred in finding that one of
ordinary skill would not have been motivated to combine
the teachings of Kahn and the Admitted Prior Art. A
patent claim is invalid “if the differences between the
subject matter sought to be patented and the prior art are
such that the subject matter as a whole would have been
obvious at the time the invention was made to a person
6                          EMERSON ELECTRIC CO.    v. SIPCO, LLC

having ordinary skill in the [relevant] art [(‘PHOSITA’)].”
35 U.S.C. § 103(a)4; KSR Int’l Co. v. Teleflex Inc., 550 U.S.
398, 406 (2007). We must “be careful not to allow hind-
sight reconstruction of references to reach the claimed
invention without any explanation as to how or why the
references would be combined to produce the claimed
invention.” Kinetic Concepts, Inc. v. Smith & Nephew,
Inc., 688 F.3d 1343, 1368 (Fed. Cir. 2012) (quoting In-
nogenetics, N.V. v. Abbott Labs., 512 F.3d 1363, 1374 n.3
(Fed. Cir. 2008)).
    We review the Board’s Final Written Decision “to en-
sure that [it is] not ‘arbitrary, capricious, an abuse of
discretion, . . . otherwise not in accordance with law . . .
[or] unsupported by substantial evidence.’” Pers. Web
Techs., LLC v. Apple, Inc., 848 F.3d 987, 992 (Fed. Cir.
2017) (quoting 5 U.S.C. § 706(2)(A), (E)) (alterations in
original). “[I]n order to ‘allow effective judicial review, . . .
the agency is obligated to “provide an administrative
record showing the evidence on which the findings are
based, accompanied by the agency’s reasoning in reaching
its conclusions.”’” Id. (quoting Synopsys, Inc. v. Mentor
Graphics Corp., 814 F.3d 1309, 1322 (Fed. Cir. 2016),
overruled in another respect by Aqua Prods., Inc. v. Matal,
872 F.3d 1290 (Fed. Cir. 2017)). “For judicial review to be
meaningfully achieved within these strictures, the agency
tribunal must present a full and reasoned explanation of

    4   Congress amended § 103 when it enacted the
Leahy-Smith America Invents Act (“AIA”).           Pub. L.
No. 112-29, § 3(c), 125 Stat. 284, 287 (2011). However,
because the application that led to the ’732 patent has
never contained (1) a claim having an effective filing date
on or after March 16, 2013, or (2) a reference under
35 U.S.C. §§ 120, 121, or 365(c) to any patent or applica-
tion that ever contained such a claim, the pre-AIA § 103
applies. See id. § 3(n)(1), 125 Stat. at 293.
EMERSON ELECTRIC CO.   v. SIPCO, LLC                     7

its decision.” In re Lee, 277 F.3d 1338, 1342 (Fed. Cir.
2002). The Board must articulate “logical and rational
reasons for [its] decision [ ].” Pers. Web, 848 F.3d at 992
(alterations in original) (quoting Synopsys, 814 F.3d
at 1322).
    At the outset, we conclude that the Board did not err
by disregarding Greeves. As we have previously acknowl-
edged, “the PTO has advised participants in its Board
proceedings that, at oral argument, ‘[a] party . . . may
only present arguments relied upon in the papers previ-
ously submitted. No new evidence or arguments may be
presented at the oral argument.’” Dell Inc. v. Acceleron,
LLC, 818 F.3d 1293, 1301 (Fed. Cir. 2016) (alterations in
original) (quoting Office Patent Trial Practice Guide,
77 Fed. Reg. 48,756, 48,768 (Aug. 14, 2012)). Under this
rule, it was improper for Emerson to rely on Greeves for
the first time at the hearing before the Board.
    Turning to the second issue on appeal, we agree with
Emerson only to the extent that the Board did not ade-
quately explain and support its conclusion that Kahn
would not have motivated one of ordinary skill in the art
to combine the teachings of Kahn and the Admitted Prior
Art for flexibility and rapid deployment. See Final Writ-
ten Decision at 12. In analyzing this issue, the Board
reproduced portions of Dr. Heppe’s declaration, the Kahn
reference, and Emerson’s briefs. Aside from those direct
quotes, the Board’s analysis consisted of only two conclu-
sory sentences: “[a]s previously noted, however, Petitioner
does not identify discussion of physical cables or wires in
Kahn,” and “Kahn, however, does not seem to discuss
such issues.” Id. at 11–12. Without any further reason-
ing, the Board concluded that Kahn does not provide a
rationale, separate from hindsight, that would have
motivated a skilled artisan to combine the teachings of
Kahn and the Admitted Prior Art.

    But the Board came to the opposite conclusion on
nearly the same facts in another inter partes review. The
’732 patent at issue here is related to U.S. Patent
No. 8,754,780, which was also subject to an inter partes
review (IPR2016-00984). Emerson Elec. Co. v. SIPCO,
LLC, No. IPR2016-00984, 2017 WL 4862106 (P.T.A.B.
Oct. 25, 2017) (“IPR2016-00984 Final Written Decision”). 5
In IPR2016-00984, the Board observed that the two
patents “share nearly the same specification” and have
“nearly identical claims.” Id. at *10. In particular,
claim 13 of the ’732 patent and claim 1 of the ’780 patent
differ only by a few words—differences the Board found
were non-substantive. In October 2017, the Board issued
a Final Written Decision in IPR2016-00984, finding
’780 patent claim 1 (and other claims) unpatentable over
the same combination of Kahn and the Admitted Prior
Art at issue here. 6 Id. at *23.
    The Board came to opposite conclusions on patentabil-
ity of these nearly identical claims despite considering
nearly identical evidence in both cases. As discussed
above, the Board found that the differences between the
two patents’ claims and specifications were non-
substantive. Both inter partes reviews considered the
same Kahn reference in searching for a motivation to
combine, although we acknowledge that the Greeves
reference was properly raised and considered by the
Board in IPR2016-00984. Dr. Heppe’s declarations were
identical in relevant part regarding motivation to com-
bine. Compare Decl. of Dr. Heppe, Ex. 1004, Emerson
Elec. Co. v. SIPCO, LLC, IPR2015-01973, J.A. 435–39,

    5   This IPR is also on appeal before this court. See
SIPCO, LLC v. Emerson Elec. Co., No. 18-1364 (Fed. Cir.
filed Dec. 21, 2017).
     6  Indeed, the same panel of Administrative Patent
Judges decided the two inter partes reviews.
EMERSON ELECTRIC CO.   v. SIPCO, LLC                          9

¶¶ 29–32 (P.T.A.B. Sept. 25, 2015), with Decl. of
Dr. Heppe, Ex. 1018, Emerson Elec. Co. v. SIPCO, LLC,
IPR2016-00984, ¶¶ 40–43 (P.T.A.B. Apr. 29, 2016). And,
in IPR2016-00984, the Board found “credible Petitioner’s
arguments and Dr. Heppe’s opinion” that “an advantage
of using wireless . . . networks was to avoid the need for
wires” and that a skilled artisan “would have been moti-
vated to use a wireless . . . network . . . to enhance flexibil-
ity in rapid deployment and reconfiguration.” IPR2016-
00984 Final Written Decision, 2017 WL 4862106, at *16.
Here, in contrast, the Board considered the same testimo-
ny and came to the opposite conclusion.
    Under these circumstances, we conclude that the
Board’s decision in this case does not adequately explain a
key element of its analysis. The decision “does not ad-
dress, or at least does not clearly address,” why the
statement in Kahn—that deployment of the packet radio
net should be rapid and convenient—does not provide a
rationale that would have motivated a skilled artisan to
combine the teachings of Kahn and the Admitted Prior
Art. Pers. Web, 848 F.3d at 993. Further, as we have
held, “where a panel simultaneously issues opinions on
the same technical issue between the same parties on the
same record, and reaches opposite results without expla-
nation, we think the best course is to vacate and remand
these findings for further consideration.” Vicor Corp. v.
SynQor, Inc., 869 F.3d 1309, 1322 (Fed. Cir. 2017).
    Some Board explanations can suffice even if brief, as
when the patent and the art are both clear and readily
understandable. Pers. Web, 848 F.3d at 994. In addition,
“we will uphold a decision of less than ideal clarity if the
agency’s path may reasonably be discerned.” Bowman
Transp., Inc. v. Ark.–Best Freight Sys., Inc., 419 U.S. 281,
286 (1974); see In re NuVasive, Inc., 842 F.3d 1376, 1382–
83 (Fed. Cir. 2016). But, understood in light of our scru-
tiny of the patent and the prior art, the Board’s “own
explanation must suffice for us to see that the agency has
10                         EMERSON ELECTRIC CO.   v. SIPCO, LLC

done its job and must be capable of being ‘reasonably . . .
discerned’ from a relatively concise [Board] discussion.”
In re NuVasive, 842 F.3d at 1383 (quoting In re Huston,
308 F.3d 1267, 1281 (Fed. Cir. 2002)). Here, the Board
did not explain why an explicit statement in Kahn regard-
ing a potential motivation to combine was not enough, nor
did it explain how it determined that impermissible
hindsight would be required to conclude that Kahn pro-
vided the requisite motivation to combine, particularly
given its seemingly opposite conclusions in IPR2016-
00984.
                             III
    We have considered the parties’ remaining arguments
and find them unpersuasive. We vacate the Board’s
decision and remand for further proceedings consistent
with this opinion, including to address the seemingly
opposite finding from the IPR2016-00984 Final Written
Decision.
