Opinion for the court filed by Circuit Judge HUGHES.
Opinion concurring in part and dissenting in part filed by
Circuit Judge DYK.
HUGHES, Circuit Judge.
This is a patent case involving a system for remote
gambling. FanDuel, Inc., appeals the final written decision
of the Patent Trial and Appeal Board in an inter partes re-
view of claims 1, 6–9, and 19 of
U.S. Patent No. 8,771,058,
which found unpatentable all challenged claims except
claim 6. FanDuel, Inc. v. Interactive Games LLC,
No. IPR2017-01491,
2018 WL 6112966 (P.T.A.B. Nov. 20,
2018) (Board Decision). The Board found that FanDuel, as
petitioner, had failed to prove that claim 6 was obvious in
view of the asserted prior art. On appeal, FanDuel argues
that the Board violated the Administrative Procedure Act
by basing this finding on obviousness issues that the patent
owner did not raise in its responses. FanDuel also chal-
lenges the Board’s factual findings regarding claim 6. Be-
cause the Board complied with the APA and its obviousness
findings are supported by substantial evidence, we affirm.
I
A
Appellee Interactive Games LLC owns the ʼ058 patent,
which describes a gaming system wherein a gaming service
provider—such as a casino—wirelessly communicates with
users’ mobile devices, allowing them to gamble remotely.
The gaming system stores rules to determine the “game
configuration” based on the location of a user’s “mobile
gaming device.” ʼ058 patent col. 6 ll. 16–19, col. 12
ll. 15–17. The specification explains that the gaming system
associates different gaming configurations with different
locations by using a “lookup table” that
may include an ordered list of locations. For exam-
ple, locations may be listed from East to West, in
Case: 19-1393 Document: 41 Page: 3 Filed: 07/29/2020
FANDUEL, INC. v. INTERACTIVE GAMES LLC 3
alphabetical order, or in any other fashion. Associ-
ated with each location may be one or more game
configurations. The [casino’s gaming system] may
receive an indication from a mobile gaming device
that the mobile gaming device has moved to a new
location. . . . [and, after] look[ing] up the new loca-
tion in its lookup table[,] . . . may determine an as-
sociated game configuration. . . . [that is then
transmitted] to the mobile gaming device.
ʼ058 patent col. 12 ll. 18–28. Independent claim 1, which
is not at issue in this appeal, generally describes altering a
user’s “game outcome” based on the gaming configuration
associated with the location of the user’s mobile gaming de-
vice.
Id. col. 60 ll. 1–28.
Claim 6, which depends from claim 1, describes the
gaming system’s use of the look-up table when associating
game configurations with locations:
6. The method of [claim] 1, in which determining
the first game configuration includes:
accessing a lookup table which contains an
ordered list of locations and associated game
configurations;
finding within the lookup table the first location;
and
determining that the first game configuration is as-
sociated with the first location.
Id. col. 60 ll. 45–51 (emphasis added).
B
FanDuel petitioned for inter partes review (IPR) of the
ʼ058 patent on several grounds of obviousness. As relevant
to this appeal, FanDuel challenged claim 6’s validity based
on the combination of three references: U.S. Patent App.
Pub. 2002/0147049 (Carter); U.S. Patent App.
Case: 19-1393 Document: 41 Page: 4 Filed: 07/29/2020
4 FANDUEL, INC. v. INTERACTIVE GAMES LLC
Pub. 2004/0005919 (Walker); and an archived copy of a
webpage (the Slot Payouts Webpage).
Carter describes a “location[-]based mobile wagering
system” “capable of determining a gambler[’]s location and,
thereby restrict[ing] access to the gaming controller based
on the gambling laws where the gambler is located.”
Carter, title, ¶ 0010. To perform this function, Carter’s
system uses a “database” that may “contain distinct loca-
tion information correlative to the physical location of [a]
gaming unit and the gaming opportunities permitted in the
jurisdiction in which the unit is located.”
Id. ¶ 0031 (nu-
merical identifiers omitted). The database is maintained
on a server and contains “jurisdictional profile[s] (e.g., ju-
risdictionally permitted gaming opportunities).”
Id.
¶¶ 0012, 0037. Carter states that this system “may employ
various integrated circuit (IC) components,” such as
“memory elements, processing elements, logic elements,
look-up tables, and the like, which may carry out a vari-
ety of functions.”
Id. ¶ 0020 (emphasis added).
Walker describes a “method and apparatus for ena-
bling a player to select features on a gaming device,” where
enabled features are stored in a “database.” Walker, title,
¶ 0116. Walker describes various “predetermined condi-
tions” that can be required for enabling certain features.
Id. ¶¶ 0107, 0124–0125, 0269–0289. One example Walker
gives of a predetermined condition is the “location or juris-
diction of a casino (e.g., a feature may be disabled within a
first geographic region, such as the state of Nevada, but
enabled within a second geographic region, such as an
American Indian reservation in the state of Arizona).”
Id.
¶ 0284; see also
id. ¶ 0264 (adjusting features based on a
player’s location within a casino).
Finally, the Slot Payouts Webpage is an archived copy
of a webpage titled “Slot Payouts by Casino / City / State.”
J.A. 3623. The webpage displays a chart of slot payout per-
centages for casinos and cities around the United States.
Case: 19-1393 Document: 41 Page: 5 Filed: 07/29/2020
FANDUEL, INC. v. INTERACTIVE GAMES LLC 5
The chart is organized alphabetically by state, with the
various cities, regions, and casinos appearing in alphabet-
ical order beneath each state.
C
The dispute here centers on whether the combination
of these three references renders obvious claim 6’s limita-
tion of determining the “game configuration” by “accessing
a lookup table which contains an ordered list of loca-
tions and associated game configurations.” ʼ058 patent
col. 60 ll. 45–48 (emphasis added).
In its IPR petition, FanDuel challenged claim 6 as ob-
vious over Carter, Walker, and the Slot Payouts Webpage.
Specifically, FanDuel argued that (1) Carter, either alone
or in combination with Walker, teaches a look-up table of
locations and associated game configurations, and (2) it
would have been obvious to “store Carter’s jurisdictional
profiles in a look-up table including an ordered list of loca-
tions and associated jurisdictional information.”
J.A. 2050–51. Relying on the opinion of its expert,
Mr. Kitchen, FanDuel asserted that it would have been “an
obvious design choice” to store Carter’s jurisdictional pro-
files in alphabetical order—as taught in the chart on the
Slot Payouts Webpage—noting that “ordered lists were ex-
tremely well-known as a way to organize information for
many years prior to the ʼ058 patent.” J.A. 2050–51 (quot-
ing Ex. 1011 ¶¶ 117–18 (Declaration of Mr. Garry
Kitchen)).
In its preliminary patent owner response, Interactive
Games argued against instituting as to claim 6 for the
same reasons that it argued against instituting as to its
parent claim 1. J.A. 2133. But the only argument Interac-
tive Games put forth defending the validity of claim 6’s
unique “lookup table” and “ordered list” limitations was
that the Slot Payouts Webpage did not qualify as prior art
to the ʼ058 patent. J.A. 2133–42.
Case: 19-1393 Document: 41 Page: 6 Filed: 07/29/2020
6 FANDUEL, INC. v. INTERACTIVE GAMES LLC
The Board instituted IPR for all the challenged claims
on some of the asserted grounds. FanDuel, Inc. v. Interac-
tive Games LLC, No. IPR2017-01491,
2017 WL 6206134,
at *1 (P.T.A.B. Nov. 22, 2017) (Institution Decision). The
Board found enough evidence to institute as to claim 6, re-
jecting—for purposes of its institution decision only—In-
teractive Games’s evidentiary arguments against
accepting the Slot Payouts Webpage as prior art. Institu-
tion Decision at *9–11 (finding that FanDuel demonstrated
“a reasonable likelihood of prevailing” on its challenge that
claim 6 was obvious over Carter, Walker, and the Slot Pay-
outs Webpage).
Following institution, Interactive Games submitted a
patent owner response. As in its preliminary response, In-
teractive Games’s only argument specific to claim 6 was
that claim 6 could not be obvious over any combination in-
cluding the Slot Payouts Webpage, because it was not prior
art. Interactive Games also submitted an expert declara-
tion, but it did not rely on that declaration to rebut Fan-
Duel’s arguments and evidence specific to claim 6.
FanDuel then filed a reply. As to the obviousness of
claim 6, FanDuel’s reply argued exclusively that the Board
should maintain its institution decision view that the Slot
Payouts Webpage is prior art. 1
1 After FanDuel filed its reply, the Board modified
its institution decision to comply with SAS Inst., Inc. v.
Iancu,
138 S. Ct. 1348 (2018). The parties filed supple-
mental papers on the initially non-instituted grounds, one
of which challenged claim 6 as obvious over the Slot Pay-
outs Webpage in combination with two different refer-
ences. In its final written decision, the Board concluded
that FanDuel did not establish the unpatentability of
claim 6 on this additional ground, Board Decision at *20,
and FanDuel has not appealed that determination.
Case: 19-1393 Document: 41 Page: 7 Filed: 07/29/2020
FANDUEL, INC. v. INTERACTIVE GAMES LLC 7
The Board issued a final written decision finding
claims 1, 7–9, and 19 unpatentable but upholding the pa-
tentability of claim 6. Board Decision at *1. The Board
found that FanDuel failed to prove claim 6 obvious in view
of Carter, Walker, and the Slot Payouts Webpage. Board
Decision at *18.
In rejecting FanDuel’s obviousness challenge to
claim 6, the Board first disagreed with FanDuel’s conten-
tion that Carter discloses “jurisdictional profiles being
stored in a database employing look-up tables.” Id. at *17.
In the Board’s view, Carter only generally references look-
up tables as one of many components that might carry out
a variety of functions and does not disclose specifically us-
ing a look-up table to correlate location information with
jurisdictionally permitted gaming opportunities, as recited
in claim 6. Id. (citing Carter ¶¶ 0020, 0031). And FanDuel
had not explained why it would have been obvious to use a
look-up table for this specific function. Id.
As to motivation to combine, the Board rejected as con-
clusory FanDuel’s sole explanation that it would be an “ob-
vious design choice” to apply the alphabetically “ordered
list” of the Slot Payouts Webpage to organize Carter’s ju-
risdictional profiles. Id. The Board concluded that Fan-
Duel, again, did not offer “any reason(s) why it would have
been beneficial to organize Carter’s database of jurisdic-
tional profiles in alphabetical order,” given that “the Slot
Payouts Webpage is meant for human reading and under-
standing, not for use by a machine such as Carter’s gaming
system.” Id. at *18. The final written decision did not dis-
cuss the earlier debated question of whether the Slot Pay-
outs Webpage qualified as prior art.
FanDuel appeals. We have jurisdiction under
28 U.S.C. § 1295(a)(4)(A) and
35 U.S.C. § 141(c).

We begin with FanDuel’s procedural challenge that the
Board violated the Administrative Procedure Act (APA).
We then address the challenge to the Board’s factual find-
ings.
A
“As formal administrative adjudications, IPRs are sub-
ject to the APA.” Hamilton Beach Brands, Inc. v. f’real
Foods, LLC,
908 F.3d 1328, 1338 (Fed. Cir. 2018) (citing
Dell Inc. v. Acceleron, LLC,
818 F.3d 1293, 1298, 1301
(Fed. Cir. 2016)). The APA requires that we, as the review-
ing court, “hold unlawful and set aside agency action . . .
not in accordance with law [or] . . . without observance of
procedure required by law.”
5 U.S.C. § 706(2). We review
de novo whether the Board’s procedures satisfy the APA.
Sirona Dental Sys. GmbH v. Institut Straumann AG,
892 F.3d 1349, 1352 (Fed. Cir. 2018).
To comply with the APA in an IPR proceeding, the
Board must “timely inform[]” the parties of “the matters of
fact and law asserted,”
5 U.S.C. § 554(b)(3); it must give the
parties an opportunity to submit facts and arguments for
consideration,
id. § 554(c); and it must permit each party
to present oral and documentary evidence in support of its
case or defense, as well as rebuttal evidence, id. § 556(d).
See Hamilton Beach Brands, 908 F.3d at 1338; Rovalma,

1029 (Fed. Cir. 2017); Belden Inc. v. Berk-Tek LLC,
805 F.3d 1064, 1080 (Fed. Cir. 2015). “Pursuant to these
provisions, the Board may not change theories midstream
without giving the parties reasonable notice of its change.”
Hamilton Beach Brands, 908 F.3d at 1338 (citing Belden,
805 F.3d at 1080 (interpreting § 554(b)(3) in the context of
IPR proceedings)).
FanDuel argues that the Board violated this maxim by
adopting in its final written decision a “new theory”—that
Case: 19-1393 Document: 41 Page: 9 Filed: 07/29/2020
FANDUEL, INC. v. INTERACTIVE GAMES LLC 9
the combination of Walker, Carter, and the Slot Payouts
Webpage failed to disclose jurisdictional profiles stored in
a database employing look-up tables including an ordered
list—which the patent owner never raised during the pro-
ceeding, having only contested the prior art status of the
Slot Payouts Webpage. Appellant’s Br. 4. Because the
Board found sufficient evidence to institute, and there was
no further record development on the claim 6 limitations
the Board addressed in its final written decision—with the
parties exclusively focusing on whether the Slot Payouts
Webpage qualified as prior art—FanDuel asserts that it
was entitled to notice and an opportunity to respond before
the Board rejected its obviousness challenge based on in-
sufficient disclosure in the asserted references.
“The critical question for compliance with the APA and
due process is whether [the appellant] received ‘adequate
notice of the issues that would be considered, and ulti-
mately resolved, at that hearing.’” Genzyme Therapeutic
Prods. Ltd. P’ship v. Biomarin Pharm. Inc.,
825 F.3d 1360,
1367 (Fed. Cir. 2016) (quoting Pub. Serv. Comm’n of Ky. v.
FERC,
397 F.3d 1004, 1012 (D.C. Cir. 2005) (Roberts, J.)).
See also Nike, Inc. v. Adidas AG,
955 F.3d 45, 54 (Fed. Cir.
2020). FanDuel’s argument that it lacked notice that the
Board might address and reject the obviousness arguments
made in FanDuel’s own petition strains credulity.
Initially, we fail to see how the Board “change[d] theo-
ries” at all in this case. By finding at institution that Fan-
Duel had a reasonable likelihood of succeeding in its
obviousness challenge to claim 6, despite one reference’s
contested prior art status, the Board was not adopting a
position on the ultimate import of the three references.
The Board said nothing in its institution decision endors-
ing FanDuel’s arguments that Carter and Walker com-
bined to teach a look-up table, or that it would have been
obvious to organize that look-up table as an ordered list
such that later rejecting these arguments would have been
a change in theory. We therefore see little benefit in
Case: 19-1393 Document: 41 Page: 10 Filed: 07/29/2020
10 FANDUEL, INC. v. INTERACTIVE GAMES LLC
comparing this case to those in which the Board at institu-
tion expressly adopted one claim construction and then
adopted a materially different claim construction in its fi-
nal written decision without giving the parties notice and
an opportunity to respond. See, e.g., SAS Inst., Inc. v. Com-
plementSoft, LLC,
825 F.3d 1341, 1346, 1351 (Fed. Cir.
2016) (identifying an APA violation where parties did not
dispute the claim construction the Board adopted at insti-
tution but the Board adopted a significantly different claim
construction in its final written decision without any fur-
ther discussion or briefing), rev’d on other grounds, SAS
Inst., Inc. v. Iancu,
138 S. Ct. 1348 (2018).
At institution, the Board focused its decision on the
prior art status issue and—without discussion—found the
three references asserted against claim 6 sufficient to in-
stitute. In its final written decision, the Board substan-
tively analyzed the three asserted references and found
them insufficient to render claim 6 obvious, without ad-
dressing whether the Slot Payouts Webpage was prior art.
To the extent the Board changed theories by doing so,
the Board was not required to first notify the parties in this
case for two somewhat overlapping reasons. First, the dif-
ferent standards of proof required to institute versus to in-
validate permit the Board to adopt different views of the
sufficiency of a petitioner’s asserted obviousness argu-
ments in its initial versus final decisions without first
alerting the parties to that possibility. At institution, the
Board need only find a reasonable likelihood that a peti-
tioner will succeed; whereas, the petitioner must ulti-
mately prove invalidity by a preponderance of the evidence.
Compare
35 U.S.C. § 314(a) (IPR may not be instituted un-
less “there is a reasonable likelihood that the petitioner
would prevail with respect to at least 1 of the claims chal-
lenged in the petition”), with
id. § 316(e) (“In an [IPR] . . . ,
the petitioner shall have the burden of proving a proposi-
tion of unpatentability by a preponderance of the evi-
dence.”); see In re Magnum Oil Tools Int’l, Ltd., 829 F.3d
Case: 19-1393 Document: 41 Page: 11 Filed: 07/29/2020
FANDUEL, INC. v. INTERACTIVE GAMES LLC 11
1364, 1376 (Fed. Cir. 2016) (“[T]he decision to institute and
the final written decision are ‘two very different analyses,’
and each applies a ‘qualitatively different standard.’”
(quoting TriVascular, Inc. v. Samuels,
812 F.3d 1056, 1068
(Fed. Cir. 2016))).
There is nothing inherently inconsistent about the
Board instituting IPR on obviousness grounds and then ul-
timately finding that the petitioner did not provide prepon-
derant evidence that the challenged claim was obvious.
This happens with some frequency. Indeed, we have en-
couraged the Board to “change its view of the merits after
further development of the record, . . . if convinced its ini-
tial inclinations were wrong.” TriVascular, 812 F.3d at
1068; see Magnum Oil, 829 F.3d at 1377 (“[T]he Board has
an obligation to assess the question anew after trial based
on the totality of the record.”). FanDuel does not argue that
the Board is bound by its institution decision findings, but
it contends, based on this statement from Trivascular, that
some further record development on a given issue must oc-
cur post-institution in order for the Board to change its
view.
TriVascular cannot be read so narrowly. For one thing,
the court in TriVascular was not reviewing an IPR proceed-
ing that lacked record development. After institution in
that case, both parties submitted expert reports regarding
the petitioner’s obviousness challenge. TriVascular, 812
F.3d at 1060. Our statements regarding the added benefits
the Board might gain from a fully developed record post-
institution simply reflected the circumstances of that case.
See id. at 1068 (explaining that at institution the Board is
considering matters “preliminarily without the benefit of a
full record” and remains “free to change its view of the mer-
its after further development of the record”). We did not
thereby announce a condition precedent that the Board can
only change its view of the record when additional argu-
ment or evidence relevant to that change is added after in-
stitution.
Case: 19-1393 Document: 41 Page: 12 Filed: 07/29/2020
12 FANDUEL, INC. v. INTERACTIVE GAMES LLC
But the main reason to reject FanDuel’s interpretation
of TriVascular dovetails with our second overall reason for
rejecting FanDuel’s APA challenge: that the burden of
proving invalidity in an IPR remains on the petitioner
throughout the proceeding.
35 U.S.C. § 316(e) (stating that
“the petitioner shall have the burden of proving a proposi-
tion of unpatentability”); see Magnum Oil, 829 F.3d at 1375
(stating that the petitioner bears the burden to prove un-
patentable the challenged claims); see also Worlds Inc. v.
Bungie, Inc.,
903 F.3d 1237, 1242 (Fed. Cir. 2018)
(“[B]ecause the IPR petitioner is the party seeking an order
from the Board, § 556(d) [of the APA] requires the peti-
tioner to bear the burden of persuasion.”).
Here, FanDuel specifically asserted in its petition that,
as to claim 6, it would have been obvious to “include
Walker’s location-specific features in Carter’s jurisdic-
tional profiles,” and to “store Carter’s jurisdictional profiles
in a look-up table including an ordered list of locations and
associated jurisdictional information.” J.A. 2049–51. Fan-
Duel supported these assertions with citations to
Dr. Kitchen’s expert opinion to the same effect and cited
various disclosures within the references. Requiring fur-
ther post-institution record development on whether these
references indeed rendered claim 6 obvious in order for the
Board to reach that question in its final decision would ef-
fectively and impermissibly shift the burden to the patent
owner to defend its claim’s patentability. See Magnum Oil,
829 F.3d at 1376 (“[I]t is inappropriate to shift the burden
to the patentee after institution to prove that the patent is
patentable.”); Dynamic Drinkware, LLC v. Nat’l Graphics,
Inc.,
800 F.3d 1375, 1378 (Fed. Cir. 2015) (“In an inter
partes review, the burden of persuasion is on the petitioner
to prove ‘unpatentability by a preponderance of the evi-
dence,’
35 U.S.C. § 316(e), and that burden never shifts to
the patentee.”).
In Magnum Oil, we soundly rejected the idea of shifting
even the burden of production from the petitioner to the
Case: 19-1393 Document: 41 Page: 13 Filed: 07/29/2020
FANDUEL, INC. v. INTERACTIVE GAMES LLC 13
patent owner once the Board institutes an IPR where “the
patentee’s position is that the patent challenger failed to
meet its burden of proving obviousness.” 829 F.3d at
1375–76. “Where, as here, the only question presented is
whether due consideration of the four Graham [obvious-
ness] factors renders a claim or claims obvious, no burden
shifts from the patent challenger to the patentee” upon in-
stitution. Id. at 1376. We therefore reject FanDuel’s sug-
gestion that the patent owner’s failure to put forth rebuttal
evidence regarding the substance of the references’ disclo-
sures in any way limited the Board’s ability to decide for
itself what the references would teach or suggest to a per-
son of skill in the art. See Rovalma, 856 F.3d at 1027 (not-
ing that the Board is not “preclude[d] . . . from relying on
arguments made by a party and doing its job, as adjudica-
tor, of drawing its own inferences and conclusions from
those arguments”).
Further confirming that the burden cannot shift to the
patentee post institution, the IPR regulations do not re-
quire a patent owner to submit any response to the peti-
tion, either before or after institution.
37 C.F.R.
§§ 42.107(a) (pre-institution, “[t]he patent owner may file a
preliminary response to the petition” (emphasis added)),
42.120(a) (post-institution, “[a] patent owner may file a re-
sponse to the petition” (emphasis added)); Magnum Oil,
829 F.3d at 1376 n.1 (“[T]he patent owner is not required
to use its opportunity under the regulations to file a patent
owner response . . . .”); see also E.I. DuPont de Nemours &
Co. v. Synvina C.V.,
904 F.3d 996, 1008 (Fed. Cir. 2018)
(“[A] patentee technically has no ‘burden’ to do anything to
defend the validity of its patent other than hold the patent
challenger to its own burden of persuasion . . . .”).
FanDuel ignores these fundamental principles when it
argues that the Board erred by deciding obviousness issues
not “raised” at any time by the patent owner, Interactive
Games. Appellant’s Br. 5. As we have just discussed, a
patent owner carries no obligation to raise any objection to
Case: 19-1393 Document: 41 Page: 14 Filed: 07/29/2020
14 FANDUEL, INC. v. INTERACTIVE GAMES LLC
the petitioner’s challenges at all. E.I. DuPont, 904 F.3d
at 1008; Magnum Oil, 829 F.3d at 1376 n.1. Thus, a patent
owner’s response, alone, does not define the universe of is-
sues the Board may address in its final written decision.
Rather, in an IPR, “the petitioner’s contentions . . . define
the scope of the litigation all the way from institution
through to conclusion.” SAS Inst.,
138 S. Ct. at 1357 (em-
phasis added). And a patent owner response ordinarily
does not narrow the range of issues previously made avail-
able to the Board in the petition. But see, e.g., SAS Inst.,
825 F.3d at 1351 (where the patent owner response did not
contest the Board’s institution decision claim construction,
the Board violated the APA by adopting in its final written
decision a materially different claim construction without
giving the parties an opportunity to present arguments
based on that claim construction).
FanDuel argues that because the patent owner’s re-
sponse regarding the patentability of claim 6 only argued
that the Slot Payouts Webpage was not prior art, and be-
cause that was the only issue specific to claim 6 that the
Board addressed in its institution decision, the prior art
status of claim 6 “was the sole issue . . . throughout the IPR
proceeding and trial.” Appellant’s Br. 4. That is not so. In
fact, the “sole issue” throughout the Board proceedings was
whether FanDuel proved its theory as to how Carter,
Walker, and the Slot Payouts Webpage combined to make
claim 6 obvious. This central question remained, regard-
less what aspects of that issue the patent owner and the
Board chose to address in their respective response and in-
itial decision. From the moment FanDuel filed its petition,
it was on notice that the Board would decide whether those
references taught what FanDuel claimed they taught.
That is exactly what the Board ultimately did. No APA
violation results from such a course.
The Board’s actions in this case do not raise the types
of concerns that have led us to identify APA violations in
previous cases. For instance, the Board here did not come
Case: 19-1393 Document: 41 Page: 15 Filed: 07/29/2020
FANDUEL, INC. v. INTERACTIVE GAMES LLC 15
up with its own novel theory of (non)obviousness. Cf. Si-
rona, 892 F.3d at 1356 (holding that it would be improper
“for the Board to deviate from the grounds in the petition
and raise its own obviousness theory”). Rather, in accord-
ance with the APA, it assessed the sufficiency of the very
obviousness theory FanDuel asserted in its petition. See
Magnum Oil, 829 F.3d at 1381 (“[T]he Board must base its
decision on arguments that were advanced by a party, and
to which the opposing party was given a chance to re-
spond.”). Nor did the Board resort to cherry-picking from
unaddressed portions of the record to reject FanDuel’s pa-
tentability challenge to claim 6. Cf. Rovalma, 856 F.3d
at 1029 (“The Board’s procedural obligations are not satis-
fied merely because a particular fact might be found some-
where amidst the evidence submitted by the parties,
without attention being called to it so as to provide ade-
quate notice and an adequate opportunity to be heard.” (cit-
ing In re NuVasive, Inc.,
841 F.3d 966, 971 (Fed. Cir.
2016))). It relied on precisely those portions of the three
asserted references on which FanDuel’s petition relied.
The Board’s purported new theory in this case was
merely an assessment of the arguments and evidence Fan-
Duel put forth in its petition. The APA does not require
the Board to alert a petitioner that it may find the asserted
theory of obviousness lacking in evidence before it actually
does so in a final written decision. Nor is a petitioner enti-
tled to a pre-decision opportunity to disagree with the
Board’s assessment of its arguments. The time to disagree
with that assessment comes after the final decision has is-
sued, in a request for Board rehearing or an appeal to this
court.

We turn now to FanDuel’s challenge to the substance
of the Board’s final written decision. “Whether a claimed
invention would have been obvious is a question of law,
based on factual determinations regarding the scope and
Case: 19-1393 Document: 41 Page: 16 Filed: 07/29/2020
16 FANDUEL, INC. v. INTERACTIVE GAMES LLC
content of the prior art, differences between the prior art
and claims at issue, the level of ordinary skill in the perti-
nent art, [and] the motivations to modify or combine prior
art . . . .” Belden, 805 F.3d at 1073. We review the Board’s
legal decisions de novo and its factual determinations for
substantial evidence. Id. Substantial evidence “means
such relevant evidence as a reasonable mind might accept
as adequate to support a conclusion.” Consol. Edison Co.
v. N.L.R.B.,
305 U.S. 197, 217 (1938).
FanDuel argues that substantial evidence does not
support the decision to sustain the patentability of claim 6.
Particularly, FanDuel contends that Carter explicitly
teaches the general use of look-up tables and that, as ex-
plained by Mr. Kitchen, a person of ordinary skill in the art
at the time of the invention would have understood that
this use of look-up tables would apply to Carter’s gaming
configurations. FanDuel argues that in reaching the con-
trary conclusion, the Board did not give appropriate defer-
ence to Mr. Kitchen’s unrebutted opinion and
impermissibly ignored his explanation that ordered lists
were extremely well-known methods of organization long
before the ʼ058 patent.
We are not persuaded. The Board properly considered
the record in its entirety, including Mr. Kitchen’s declara-
tion, before finding that FanDuel had not met its burden.
Board Decision at *16–18. As FanDuel acknowledges,
Carter only teaches the general use of look-up tables. The
Board’s final written decision repeatedly cites the para-
graph containing Mr. Kitchen’s opinion that look-up tables
were very well-known, but it reasonably found that Fan-
Duel had not provided sufficient evidence for why a person
of skill would be motivated to add a look-up table (such as
the chart included on the Slot Payouts Webpage) to corre-
late location information with game configurations. The
Board reasonably identified a gap between the concept of a
look-up table being well-known and the beneficial applica-
tion of that concept to Carter’s gaming system. It
Case: 19-1393 Document: 41 Page: 17 Filed: 07/29/2020
FANDUEL, INC. v. INTERACTIVE GAMES LLC 17
substantiated that evidentiary gap by noting that it was
unclear how a machine-based, automated gaming system
like Carter’s would benefit from an alphabetized look-up
table like the Slot Payouts Webpage chart designed to al-
low a human reader to locate information of interest. See
Board Decision at *18. And it reasonably found that simply
calling the addition of a look-up table “an obvious design
choice” did not fill that gap. Thus, substantial evidence
supports the Board’s rejection of FanDuel’s obviousness
challenge to claim 6 of the ʼ058 patent.
Finally, there is no merit to FanDuel’s suggestion that
the Board was somehow obligated to defer to Mr. Kitchen’s
expert opinion of claim 6’s unpatentability just because the
patent owner in this case did not supply opposing expert
guidance. As mentioned in discussing the APA challenge,
it is the Board’s duty to independently assess the strength
of a petitioner’s argument and evidence. Rovalma,
856 F.3d at 1027. While the Board may appreciate receiv-
ing expert opinion from both sides to help it do so, no expert
submissions are required. See Belden, 805 F.3d at 1079
(Fed. Cir. 2015) (“No rule requires . . . an expert guiding
the Board as to how it should read prior art.”); VirnetX Inc.
v. Apple Inc., 665 F. App’x 880, 884–85, 889 (Fed. Cir. 2016)
(interpreting Belden as holding that the “PTAB may make
factual findings absent expert testimony”). Indeed, “Board
members, because of expertise, may more often find it eas-
ier to understand and soundly explain the teachings and
suggestions of prior art without expert assistance.” Belden,
805 F.3d at 1079.
Certainly, the Board cannot “simply reach conclusions
based on its own understanding or experience—or on its
assessment of what would be basic knowledge or common
sense.” In re Zurko,
258 F.3d 1379, 1386 (Fed. Cir. 2001)
(reversing the Board’s affirmance of an examiner’s obvious-
ness rejection where the Board failed to identify “concrete
evidence in the record” supporting its findings). And what
the Board can find without an expert depends on the prior
Case: 19-1393 Document: 41 Page: 18 Filed: 07/29/2020
18 FANDUEL, INC. v. INTERACTIVE GAMES LLC
art involved in the case. Synopsys, Inc. v. Mentor Graphics
Corp.,
814 F.3d 1309, 1320 (Fed. Cir. 2016). But in every
case, it remains the Board’s essential function to make fac-
tual findings based on its view of the record. Here, the
Board found as a factual matter that, even with
Mr. Kitchen’s explanation that ordered lists were well-
known, there was insufficient evidence that a person of
skill would include such lists in Carter’s jurisdictional pro-
files. The Board explained its reasons for disagreeing with
Mr. Kitchen’s opinion, pointing to specific passages in
Carter that detracted from his position. There was no need
for the Board to rely on an expert to corroborate its reading
of the asserted disclosures.

We have considered FanDuel’s remaining arguments
and find them unpersuasive. For the foregoing reasons, we
affirm the Board’s final written decision.

DYK, Circuit Judge, concurring in part and dissenting in

I join Part II-A of the majority opinion rejecting Fan-
Duel’s procedural challenge, but I respectfully dissent from
the majority’s affirmance of the Board’s obviousness deter-
mination. I would hold that the Board erred when it deter-
mined that FanDuel failed to show that claim 6 of the ’058
patent would have been obvious because the Board used an
incorrect standard for obviousness.
I
The ’058 patent is directed to systems and methods for
remote gambling wherein the “game configuration,” i.e.,
game rules, is based on the location of the user’s “mobile
Case: 19-1393 Document: 41 Page: 20 Filed: 07/29/2020
2 FANDUEL, INC. v. INTERACTIVE GAMES LLC
gaming device.” ’058 patent col. 6 ll. 16–19, col. 12 ll.15–
17. Claim 1 recites that the remote gambling system “de-
termin[es] a first location of a mobile gaming device[ and]
determin[es] a first game configuration associated with the
first location.”
Id. col. 60 ll. 3–5. This claim has been held
unpatentable. The only claim at issue is claim 6, which
depends on claim 1, and adds the following limitation: “de-
termining the first game configuration includes: accessing
a lookup table which contains an ordered list of locations
and associated game configurations; finding within the
lookup table the first location; and determining that the
first game configuration is associated with the first loca-
tion.”
Id. col. 60 ll. 45–51. The question before the Board
was whether this limitation distinguished claim 6 from
claim 1 for purposes of obviousness.
II
Before the Board, there appears to have been no dis-
pute that both the look-up table and ordered list recited in
claim 6 were well-known in the art. FanDuel’s expert tes-
tified, without contradiction, that “[a] person having ordi-
nary skill in the art would have understood that ordered
lists were extremely well-known as a way to organize in-
formation for many years prior to the ’058 Patent,” as were
look-up tables, which were in use as early as 1979.
J.A. 3807 & n.3. The prior art patent (Carter) relied on by
the Board to hold unpatentable claim 1 specifically men-
tioned the use of look-up tables as a well-known and ge-
neric element. Carter at ¶ 20 (“[T]he present invention
may employ . . . look-up tables[] . . . which may carry out a
variety of functions . . . .”). The patentee did not dispute
that look-up tables and ordered lists were well-known. 1
1 See Maj. Op. at 5 (noting that “the only argument
Interactive Games put forth [before the Board] defending
the validity of claim 6’s unique ‘lookup table’ and ‘ordered

FANDUEL, INC. v. INTERACTIVE GAMES LLC 3
That look-up tables and ordered lists were well-known also
appears not to be disputed by the Board or the majority.
See Maj. Op. at 16. Furthermore, FanDuel’s expert testi-
fied without contradiction that a person of ordinary skill in
the art would have recognized that Carter’s jurisdictional
profiles would be implemented using a look-up table, and
that an ordered list was an “obvious design choice” for stor-
ing the jurisdictional profiles. 2 J.A. 3807–09. That testi-
mony was consistent with the specification of the ’058
patent, which attributed no novelty at all to the use of ei-
ther a look-up table or an ordered list. See ’058 patent
col. 51 ll. 63–67;
id. at col. 12 ll. 18–20.
III
Despite this evidence, the Board found that claim 6 was
not shown to be obvious under an impermissibly rigid view
of the prior art requiring a specific motivation to combine
look-up tables and ordered lists to implement Carter’s ju-
risdictional profiles. First, the Board found that Carter did
not “disclose that a look-up table, specifically, provides the
correlation between the location information and the juris-
dictionally permitted gaming opportunities,” and that Fan-
Duel had not provided an express motivation to “use a look-
up table as the specific method for correlating location in-
formation with jurisdictionally permitted gaming opportu-
nities, based on Carter’s disclosure or otherwise.” Board
Decision at 41. Second, the Board found that the Slot Pay-
outs Webpage did not specifically disclose the use of an or-
dered list of locations for “use by a machine such as Carter’s
list’ limitations was that the Slot Payouts Webpage did not
qualify as prior art to the ’058 patent” (emphasis added)).
2 See Imperium IP Holdings (Cayman), Ltd. v. Sam-
sung Elecs. Co., 757 F. App’x 974, 979–80 (Fed. Cir. 2019)
(noting that, while a factfinder has “wide leeway to assess
evidence and credibility,” it must “have some reasonable
basis” for rejecting uncontroverted expert testimony).

gaming system,” and that FanDuel had not provided an ex-
press motivation for “why it would have been beneficial to
organize Carter’s database of jurisdictional profiles in al-
phabetical order.”
Id. at 42.
The majority appears to agree with the Board that
showing that look-up tables and ordered lists were well-
known design choices was not sufficient to show a motiva-
tion to combine. It concludes that the Board “reasonably
identified a gap between the concept of a look-up table be-
ing well-known and the beneficial application of that con-
cept to Carter’s gaming system,” and “reasonably found
that simply calling the addition of a look-up table ‘an obvi-
ous design choice’ did not fill that gap.” Maj. Op. at 16–17.
Similarly, the majority holds that the Board reasonably
found that, “even with Mr. Kitchen’s explanation that or-
dered lists were well-known, there was insufficient evi-
dence that a person of skill would include such lists in
Carter’s jurisdictional profiles.”
Id. at 18.
The Board’s view of what was required is simply wrong.
KSR requires an “expansive and flexible approach.” KSR
Int’l Co. v. Teleflex Inc.,
550 U.S. 398, 415 (2007). “The
combination of familiar elements according to known meth-
ods is likely to be obvious when it does no more than yield
predictable results.”
Id. at 416. We have repeatedly
acknowledged this aspect of KSR. See Uber Techs., Inc. v.
X One, Inc.,
957 F.3d 1334, 1338 (Fed. Cir. 2020); CRFD
Rsch., Inc. v. Matal,
876 F.3d 1330, 1347 (Fed. Cir. 2017);
Wyers v. Master Lock Co.,
616 F.3d 1231, 1238 (Fed. Cir.
2010). In Uber, we explained that, when the record shows
“‘a finite number of identified, predictable solutions’ to a
design need that existed at the relevant time, which a per-
son of ordinary skill in the art ‘ha[d] a good reason to pur-
sue,’” “common sense” can supply a motivation to combine.
Uber, 957 F.3d at 1339–40 (alteration in original) (quoting
KSR,
550 U.S. at 421). In CRFD, we explained that “a per-
son of ordinary skill [provided] with a simple design choice”
to address a problem is presumed to “‘ha[ve] a good reason
Case: 19-1393 Document: 41 Page: 23 Filed: 07/29/2020
FANDUEL, INC. v. INTERACTIVE GAMES LLC 5
to pursue the known options within his or her technical
grasp.’” CRFD, 876 F.3d at 1347 (quoting KSR,
550 U.S.
at 421).
Obviousness is particularly apparent where “the al-
leged novelty of the . . . patent is not related to the differ-
ences between” “‘a finite number of identified, predictable
solutions,’” identified in the prior art. Uber, 957 F.3d at
1339 (quoting KSR,
550 U.S. at 421). Because the use of a
look-up table and an ordered list was only one of a number
of finite, “predictable solutions,” it would have been obvious
to “us[e] a technique that was known to one of ordinary
skill in the art.” Id. at 1340. The Board erred by requiring
FanDuel to supply a specific motivation to use a look-up
table and ordered list in this particular context when that
choice would have been a simple alternative design choice
to a skilled artisan.
Because, as a matter of law, the Board incorrectly con-
cluded that FanDuel failed to show that claim 6 of the ’058
patent would have been obvious, I would reverse the
Board’s obviousness determination.
