The Proposed Ground of Unpatentability
Petitioner challenges claims 11–25 of the ’833 patent as unpatentable
over Lee, Tucker, Henderson, and Amer. Pet. 7.
ANALYSIS
A. Claim Construction
We construe the claims “using the same claim construction standard
that would be used to construe the claim in a civil action under 35 U.S.C.
[§] 282(b), including construing the claim in accordance with the ordinary
and customary meaning of such claim as understood by one of ordinary skill
in the art and the prosecution history pertaining to the patent” See Changes
to the Claim Construction Standard for Interpreting Claims in Trial
Proceedings Before the Patent Trial and Appeal Board, 83 Fed. Reg. 51,340,
51,340, 51,358 (Oct. 11, 2018) (amending 37 C.F.R. § 42.100(b) effective
November 13, 2018) (now codified at 37 C.F.R. § 42.100(b) (2019));
Phillips v. AWH Corp., 415 F.3d 1303, 1312–13 (Fed. Cir. 2005).
PGR2019-00035
Patent 10,218,833 B2

Neither party offers any proposed constructions for any claim terms.
See Pet. 33; PO Resp. 18. Specifically, Petitioner indicates “that no claim
terms require construction” and that “[e]ach claim term should be given its
plain and customary meaning as understood by one of ordinary skill in the
art.” Pet. 33 (citing Ex 1102 ¶112). Patent Owner also indicates, “[f]or
purposes of this Patent Owner Response, . . . no claim construction is
necessary[.]” PO. Resp. 18. On this record and for purposes of this
decision, we determine no claim term requires express construction. See
Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013,
1017 (Fed. Cir. 2017) (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc.,
200 F.3d 795, 803 (Fed. Cir. 1999)).
B. Legal Standards
Petitioner challenges the patentability of claims 11–25 on the grounds
that the claims would have been obvious in light of various references
including: Lee, Tucker, Henderson, and Amer. To prevail in its challenges
to the patentability of the claims, Petitioner “has the burden of proving a
proposition of unpatentability by a preponderance of the evidence.” 35
U.S.C. § 326(e) (2018); see 37 C.F.R. § 42.1(d) (2019).
The Supreme Court in KSR International Co. v. Teleflex Inc., 550
U.S. 398 (2107), reaffirmed the framework for determining obviousness as
set forth in Graham v. John Deere Co., 383 U.S. 1 (1966). The KSR Court
summarized the four factual inquiries set forth in Graham that we apply in
determining whether a claim is unpatentable as obvious under 35 U.S.C.
§ 103(a) as follows: (1) determining the scope and content of the prior art,
(2) ascertaining the differences between the prior art and the claims at issue,
(3) resolving the level of ordinary skill in the pertinent art, and
PGR2019-00035
Patent 10,218,833 B2

9
(4) considering objective evidence indicating obviousness or non-
obviousness. KSR, 550 U.S. at 406 (citing Graham, 383 U.S. at 17–18).
“To satisfy its burden of proving obviousness, a petitioner cannot employ
merely conclusory statements. The petitioner must instead articulate
specific reasoning, based on evidence of record, to support the legal
conclusion of obviousness.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d
1364, 1380–81 (Fed. Cir. 2016) (citing KSR, 550 U.S. at 418). We consider
the asserted grounds based on obviousness with the principles identified
above in mind.
C. Level of Ordinary Skill in the Art
The level of skill in the art is a factual determination that provides a
primary guarantee of objectivity in an obviousness analysis. Al-Site Corp. v.
VSI Int’l Inc., 174 F.3d 1308, 1324 (Fed. Cir. 1999) (citing Graham v. John
Deere Co., 383 U.S. 1, 17–18 (1966). Petitioner asserts that a person of
ordinary skill in the art at the time of the invention “would have a [Bachelor
of Science] degree in Computer Science or an equivalent field, as well as at
least two years of academic or industry experience related to Internet
connectivity, Internet content delivery, network applications and user
application programming or web interface design, and familiarity with smart
home appliances.” Pet. 33–34 (citing Ex. 1102 ¶¶ 39–42).
Patent Owner argues that Petitioner’s “definition of a [person of
ordinary skill in the art] is incorrect because it does not account for the
context of the invention.” PO Resp. 19 (citing Ex. 2107 ¶¶ 34–37, 69–72).
According to the Patent Owner,
Properly considering the relevant factors in the field of
outdoor appliances like grills and smokers, the actual level of
PGR2019-00035
Patent 10,218,833 B2

10
ordinary skill in the art at the time of the invention was a person
with a bachelor’s of science degree in mechanical engineering
(or technical degree with equivalent experience) and awareness
of appropriate methods for remotely controlling an outdoor
appliance.
Id. at 20 (citing Ex. 2107 ¶¶ 5–7, 40–68). Patent Owner, thus, is of the view
that a skilled artisan is particularly focused on control of outdoor appliances.
Patent Owner also contends that one of ordinary skill would view safety
concerns pertaining to outdoor cooking appliances as paramount. See, e.g.,
PO Sur-Reply 3–4.
Factors that may be considered in determining level of ordinary
skill in the art include: (1) the educational level of the inventor;
(2) type of problems encountered in the art; (3) prior art solutions
to those problems; (4) rapidity with which innovations are made;
(5) sophistication of the technology; and (6) educational level of
active workers in the field[.]
Daiichi Sankyo Co., Ltd. v. Apotex, Inc., 501 F.3d 1254, 1256 (Fed. Cir.
2107) (citations omitted). “These factors are not exhaustive but are merely a
guide to determining the level of ordinary skill in the art.” Id.
The ’833 patent, in its Background, discusses that “Bluetooth radios
allow communication with nearby electronic devices including cell phones
or tablets of the appliance’s owner.” Ex. 1101, 1:40–42. The ’833 patent
further describes that “[r]ange limitations to the Bluetooth radio, however,
necessitate that the user of the appliance still be within a certain proximity of
the appliance.” Id. at 1:42–44. Thus, it is apparent from the ’833 patent that
Bluetooth, a communications technology, was the prior art solution to
allowing communication with various electronic devices, including
appliances and cell phones. Additionally, the claims of the ’833 patent are
directed to communication between various elements including a cloud, a
PGR2019-00035
Patent 10,218,833 B2

11
mobile device, transmitters, and receivers and the accompanying software
applications rather than matters pertaining to safety concerns of the grill.
We further observe that the ’833 patent describes the following:
[t]hose skilled in the art will appreciate that the principles
described herein may be practiced in network computing
environments with many types of computing system
configurations, including, personal computers, desktop
computers, laptop computers, message processors, hand-held
devices, multi-processor systems, microprocessor-based or
programmable consumer electronics, network PCs,
minicomputers, mainframe computers, mobile telephones,
PDAs, tablets, pagers, routers, switches, and the like.
Ex. 1101, 4:54–62. The ’833 patent also explains that those principles are
“practiced in a cloud computing environment.” Id. at 5:6–8. Therefore,
based on the record before us, we determine that the sophistication of the
technology of the ’833 patent is of a level requiring knowledge of computer
systems and, particularly, cloud computing environments communicating
with multiple devices.
Lastly, we note that Patent Owner relies on Mr. Minoli (Ex. 2106) as
its expert declarant in challenging the grounds of unpatentability. Mr.
Minoli indicates he is “a telecommunications practitioner with 44 years of
data communications, telecommunications, cloud computing, Internet,
wireless, and Internet of Things (IoT) experience.” Id. ¶ 9, Appendix A. Mr.
Minoli also sets forth that he has a Master of Science in Computer Science
and both a Bachelor and Master of Science in Mathematics. Id. at Appendix
A. Thus, in arguing the patentability of the disputed claims, Patent Owner
itself relies on a declarant having both a degree in Computer Science and at
least two years industry experience related to Internet connectivity, Internet
content delivery, and network applications.
PGR2019-00035
Patent 10,218,833 B2

12
We have considered the record before us and determine that, it is
Petitioner’s description of an ordinarily skilled artisan that is better
supported by the record.3 However, we delete the qualifier
“at least” with regard to the number of years of academic or industry
experience, because its inclusion extends the level to that of an expert
beyond the level of ordinary skill. We note also that the applied prior art
reflects the appropriate level of skill at the time of the claimed invention.
See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).
D. References Relied Upon
1. Overview of Lee
Lee is titled “Cloud-Based Data Server Providing Home Appliance
Management Service and Method Thereof,” and discloses a “cloud-based
data server providing a user of a terminal apparatus with a management
service for one or more home appliances” so that “the user of the terminal
apparatus may remotely monitor states of the home appliances or control
actions or operations of the home appliances in a home network system.”
Ex. 1103, codes (54), (57). Figure 1 of Lee, reproduced below, illustrates “a
system in which states of one or more home appliances 150 may be
monitored and functions or operations of the home appliances 150 may be
controlled, using a terminal apparatus 160 of a user.” Id. ¶ 55.

3 Patent Owner does not contend that the parties’ disagreement as to level of
ordinary skill in the art would affect any determination in this Decision. See
id. at 21.
PGR2019-00035

Figure 1 illustrates a system for monitoring and controlling home
appliances. Id. As shown, Lee’s “system for managing the home appliances
150” includes “cloud-based data server 110,” “terminal apparatus 160”
connected to “cloud-based data server 110,” and “home network system 120
connected to the [cloud-based] data server 110.” Id. ¶¶ 55–58. Further,
home network system 120 includes “home gateway 130” connected to home
appliances 150. Id. ¶¶ 58–59, 62. Terminal apparatus 160 monitors home
appliances 150 through metadata generated by the home appliances. Id.
¶¶ 65–69. Figure 5, reproduced below, is a signal flow chart illustrating the
signals generated and transmitted to monitor home appliances.

Figure 5 illustrates signals transmitted between networked devices.
Id. ¶ 47. Initially, “each of the home appliances 150 may generate
information . . . related to a current state of each home appliance.” Id. ¶ 175;
see id. ¶ 68. The “information generated by each home appliance may
correspond to metadata associated with each home appliance.” Id. ¶ 175. In
particular, “metadata includ[es] at least one piece of state information on a
state of each of the home appliances 150.” Id. ¶ 190; see id. ¶¶ 168, 204. In
operation 525, that metadata is transmitted from the home appliance to the
home gateway’s device subscription function module (DSFM). Id. ¶ 187.
Then, in operation 535, home gateway 130 “may transfer the metadata
from the home appliances 150 to . . . the data server 110.” Id. ¶ 194, Fig. 5;
see id. ¶ 67. Next, in operation 545, data server 110’s monitoring service
module (MSM) “may receive, from the terminal apparatus 160, a request
PGR2019-00035
Patent 10,218,833 B2

signal with respect to the metadata.” Id. ¶ 201, Fig. 5. Subsequently, in
operation 555, “[the] data server 110’s M[S]M 245 may transfer the received
metadata to the terminal apparatus 160.” Id. ¶ 203, Fig. 5; see id. ¶ 66. As
discussed above, “[t]he metadata transferred to the terminal apparatus 160
may include information on states of the home appliances 150” (id. ¶ 203),
thus providing “a service for monitoring the home appliances 150 to the user
of the terminal apparatus 160” (id. ¶ 66).
2. Overview of Tucker
Tucker, a U.S. Patent titled “Pellet Grill,” discloses “an automated
self-contained pellet grill” that uses “compressed hardwood sawdust” as
cooking fuel. Ex. 1104, codes (54), (57), 1:19–20. Tucker further teaches
that its pellet grill includes “a communication device to exchange data
wirelessly with a remote control device.” Id. at 4:33–45.
3. Overview of Henderson
Henderson is titled “Remote-Controlled Food-Related Appliance,”
and discloses a “smoking appliance and [a] remote computing device . . . in
communication via [a] communication network” such that “a user of the
remote computing device controls the smoking appliance remotely.” Ex.
1105, codes (54), (57). Figure 1 of Henderson, reproduced below, illustrates
an example system in which “the smoking appliance 102 and remote
computing device 104 are in communication via the communication network
106.” Id. ¶ 13.
PGR2019-00035

Figure 1 illustrates a cooking system operating over a network. Id.
¶ 5. Henderson describes that, in one example, “the smoking appliance 102
is connected to the communication network 106. The communication
network 106 is, in turn, connected to the remote computing device 104.” Id.
¶ 16. Further, Henderson describes that its “smoking appliance 102
functions to, in any combination, cook, smoke, grill, bake, broil, blanch,
braise, roast or steam, food.” Id. ¶¶ 14–15.
4. Overview of Amer
Amer is titled “System and Method for Remotely Controlling IR-
Enabled Appliances via Networked Device,” and discloses a system that
“enables one or multiple users to control, monitor, and manage their
appliances (e.g., air conditioners, television sets, multimedia systems,
PGR2019-00035
Patent 10,218,833 B2

17
window curtains, etc.) both locally and remotely.” Ex. 1106, codes (54),
(57). Figure 2 of Amer is reproduced below.

Figure 2 shows components and relationships between those
components for the remote control and monitoring of appliances. Id. ¶¶ 5,
49. In Figure 2, “electric appliances 20 denoted by reference numerals 21,
22, and 24” are associated with respective “cloud-enabled remote control
devices 10” (id. ¶¶ 49, 53) which control those electric appliances 20 via,
e.g., IR control signals (id. ¶ 41). Further, “[t]he cloud platform 50 acts as a
bridge between . . . [cloud-enabled remote control] devices 10, mobile
devices 60, and web applications 61.” Id. ¶ 50. “The user 30 can control,
monitor, and manage their . . . electric appliances 20” through cloud
platform 50’s network connection to the cloud-enabled remote control
devices 10. Id. ¶ 53.

E. Obviousness Under 35 U.S.C. § 103
Petitioner contends claims 11–25 of the ’833 patent would have been
obvious over Lee, Tucker, Henderson, and Amer. Pet. 34–101. Petitioner
argues that all the features of those claims are present in the prior art. Id. at
34–38, 44–45, 48–101. Petitioner also argues that a skilled artisan would
have had adequate reason to combine the teachings of Lee, Tucker, and
Henderson. Id. at 38–43, 46–48 (citing Ex. 1102 ¶¶ 143–148).
Patent Owner has a different view than Petitioner. Patent Owner
contends that Petitioner has not accounted adequately for all features that are
required by claim 1, and that Petitioner has not set forth sufficient reason to
combine the teachings of the prior art. We focus below on certain of the
features that Patent Owner contends are absent from the record.
1. “receiving an indication from one or more remote computing
systems indicating that the electronically-controlled wood-pellet
grill is communicably connected to one or more remote computing
systems.”
Among other limitations, claim 11 recites “receiving an indication
from one or more remote computing systems indicating that the
electronically-controlled wood-pellet grill is communicably connected to
one or more remote computing systems.” Id. at 14:60–64.4 Patent Owner
initially focuses its challenge to Petitioner’s ground of unpatentability on the
requirement that an “indication” is received and conveys that the grill is

4 Independent claim 18 recites a similar limitation: “a notification field
configured to indicate whether the electronically-controlled wood-pellet grill
is communicably connected to the one or more remote computing systems.”
Ex. 1101, 15:56–16:2.
PGR2019-00035
Patent 10,218,833 B2

19
“communicably connected to” the one or more remote computing systems,
i.e. the cloud system. PO Resp. 21–27.
With respect to each of claims 11 and 18, Petitioner contends that
“Lee and Tucker collectively disclose this limitation.” Pet. 50, 80.5 Lee’s
Figure 5, as annotated by Petitioner, is reproduced below.

5 Petitioner relies on Tucker in connection with the noted limitation for only
the particular recitation in the claim of a “wood-pellet grill.” Pet. 53, 82.

Figure 5 above “is a signal flowchart illustrating a method of
providing a home appliance management service according to an
embodiment of the present invention.” Ex. 1103 ¶ 47. Petitioner urges that
“[s]tep 555 shows a transmission of data from the cloud-based data server
110 to the terminal apparatus 160—i.e., the user’s mobile device.” Pet. 50–
51, 80–81 (citing Ex. 1103 ¶ 203).
Petitioner asserts two different arguments: first, “the metadata
includes connectivity information, and, second, the signal itself indicates
there’s a connection” (Tr. 11:18–12:6). We address each of those
arguments.
With respect to the first argument, according to Petitioner, Lee
explains that step 555 describes transmitted data as “metadata” that can
“include at least one piece of state information on a state of each of the home
appliances 150, service information related to a function of each home
appliance and information on a command code requested to control each
home appliance.” Pet. 51–52 (quoting Ex. 1103 ¶ 68; Ex. 1102 ¶ 160); Pet.
81 (citing Ex. 1102 ¶ 263). Petitioner also contends that one of ordinary
skill in the art would have understood from Lee’s disclosure that the state
information of the appliance transmitted “includes data indicating that the
appliance is in network communication with the cloud-based data server”
and which “indicates that the home appliance is communicably connected to
the cloud.” Id. at 52 (citing Ex. 1102 ¶¶ 160–162).
For the purpose of instituting trial, and on the record that was then
before us, we accepted Petitioner’s position that Lee’s metadata, including
“state information” of an appliance, would have been understood by a
skilled artisan to include data indicating that an appliance is communicably
PGR2019-00035
Patent 10,218,833 B2

21
connected with the cloud. Inst. Dec. 24–25. In initially accepting that
position, we credited the testimony of Petitioner’s declarant, Dr. Houh, who
testified of such understanding by one of ordinary skill in the art. Id.
(crediting Ex. 1102 ¶ 162). We, however, noted that Patent Owner, at the
time, had not yet offered any countervailing testimony from its own expert
or cross-examined Dr. Houh on the matter. Id. at 25. Patent Owner has now
availed itself of the opportunity to do both.
With support from the testimony of its declarant, Mr. Minoli (Ex.
2106), Patent Owner now argues that Lee provides no disclosure of “how the
network connectivity of an appliance is indicated, monitored, or otherwise
reported.” PO Resp. 23 (citing Ex. 2106 ¶ 91). To that end, Patent Owner
submits that Lee simply assumes that a valid network connection exists and
that “there is nothing in Lee that would need to indicate network
communication—by ‘metadata’ or otherwise.” Id. (citing Ex. 2106 ¶ 91
(e.g., “[g]iven that Lee simply assumes a priori network connectivity, Lee
does not disclose any metadata that would indicate that the appliance is
communicably connected with the cloud”); Ex. 1103 ¶¶ 63, 70–73). In
reviewing Lee’s disclosure, we discern that Lee conveys that appliances 150
generally are connected to a home network via a connection that is
established based on “universal plug and play (UPnP),” but Lee is less than
specific in conveying that it recognized the presence of an active indication
of communication between the network and the appliances. See, e.g., Ex.
1103 ¶ 63 (“The home appliances 150 may be connected to the home
gateway 130 through a home network in wired, and wireless fashion. The
home network may be established based on universal plug and play
(UPnP).”)
PGR2019-00035

22
Petitioner and Dr. Houh infer from Lee’s disclosure of supplying
“state information” for an appliance that there is an intrinsic indication that
the information conveyed includes that the appliance is connected to a
network and presently is available to communicate. See, e.g., Pet. 51–53
(citing Ex. 1102 ¶¶ 161–163; Ex. 1103 ¶¶ 68, 194, 203). Careful review of
Dr. Houh’s testimony and Petitioner’s assessment of the cited portions of
Lee, however, reveals that they are predicated on a proposed expansive
meaning of “state information” that is not well supported in the record at
hand. We do not discern from the evidence before us that “state
information” has a particular definition in Lee or an otherwise widely-
accepted meaning. Petitioner and Dr. Houh characterize Lee’s disclosure as
presenting a meaning of “metadata” that is “broad and non-limiting in
scope” and thus necessarily includes an indication of an appliance’s
communication capability. Pet. Reply 11; Ex. 1146 ¶ 16. To that end,
Petitioner’s approach evidently is premised on a view that, based on Lee’s
disclosure, a skilled artisan would understand “state information” of an
appliance to include all possible information pertaining to the appliance,
including current network connectivity information.
As Patent Owner observes, however, Lee does provide several explicit
examples of “state information” that seemingly dictate that the type of
information that is “state information” is not so expansive as Petitioner
advances. See PO Resp. 23–24 (citing Ex. 2106 ¶ 92). We also find
credible Mr. Minoli’s testimony that, given the lack of any explicit or widely
understood definition of “state information,” “one of skill in the art would
look to the examples in Lee to gain an understanding of what Lee means by
‘state information’.” Ex. 2106 ¶ 92. We agree that Lee’s examples
PGR2019-00035
Patent 10,218,833 B2

23
reasonably would inform a skilled artisan as to the meaning of “state
information.”
For instance, in connection with a refrigerator appliance, the collected
metadata is described as data derived from sensors measuring temperature or
which may generate information or the expiration date of food contained
therein. See Ex. 1103 ¶¶ 221–225. With respect to an appliance that is a
humidifier, Lee describes that the state information relayed may be that
pertaining to the water level of a water tank. See id. ¶ 226. Patent Owner
and Mr. Minoli characterize the type of information contemplated in Lee as
“state information” as being related to “appliance-specific features” and “not
generic network connectivity.” PO Resp. 25–26; Ex. 2106 ¶ 95. We discern
that none of Lee’s expressed examples pertains or relates to an appliance’s
network connectivity status. Thus, we conclude that the record is nebulous
in conveying that a skilled artisan would associate information pertaining to
the status of an appliance’s network connectivity with Lee’s disclosed “state
information” of an appliance.
Even assuming that network connectivity information reasonably can
be regarded as state information, it does not follow from Lee’s broad
disclosure of transmitting other kinds of state information that network
connectivity information would be included in the transmission. Petitioner
does not point to any disclosure in Lee that all information about the state of
the appliance would be transmitted, without exception. Further, Petitioner
points to no disclosure that any sensor exists in Lee’s appliance to monitor
its own network connectivity to create such state information.

PGR2019-00035
Patent 10,218,833 B2

24
We also are mindful of Petitioner’s second view that the very action
of transmitting signal 555, with metadata, to terminal apparatus 160
constitutes an “indication” that the appliance is communicably connected to
the cloud. See, e.g., Pet. Reply 10 (“As explained in the Petition (Pet. 50–
53), the claimed ‘indication” is Lee’s signal 555”). In particular, Petitioner
contends the following:
Since the metadata is generated by the home appliance and
received by the data server, one skilled in the art would have
understood that the metadata input signal to the cloud-based data
server (step 535) indicates that the home appliance is
communicably connected to the cloud. That very same metadata
–– or portion thereof –– is what is transmitted to the user’s
smartphone in step 555. Thus, a skilled artisan regarding Lee’s
Figure 5 would have understood that the metadata transmitted to
the smartphone in step 555 pertains to whether the appliance is
communicably connected to the cloud.
Pet. 52 (citations omitted). “Lee’s Step 555 still must indicate that the
appliance is communicably connected because the only way that metadata
gets to the user’s terminal apparatus is by passing through the data server,
which would indicate that the appliance is communicably connected to that
data server.” Tr. 12:2–6. Dr. Houh also testifies to that effect. See Ex. 1146
¶ 14 (“[Petitioner’s] Petition makes clear that Lee’s signal 555 is the claimed
‘indication’ (Pet. 50–53).”
Claim 1 requires an “indication” that the wood-pellet grill “is
communicably connected.” The nature of “is” in that context is that the
indication must be about the present communicable connection status of the
grill. Petitioner notes that the claims do not expressly require “current”
cloud connectivity. Pet. Reply 12. Petitioner, however, does not explain
why the absence of the term “current” changes the plain meaning of the term
PGR2019-00035
Patent 10,218,833 B2

25
“is communicably connected” to not require the grill’s present or current
communicable connection condition.
Petitioner takes the position that Lee’s disclosure that metadata may
be “immediately” sent “upon request” means that the metadata necessarily
reflects current information of the appliance. Id. (citing Ex. 1003 ¶¶ 133,
146, 151, 184–185). Lee provides no indication, however, that the metadata
sent in step 555 indicates the cloud-based server and home appliance are still
connected. Because Lee discloses that the metadata may be stored (Ex.
1003 ¶¶ 133, 146, 151, 184–185), there is no preclusion that, at the time of
the request for the metadata, the home appliance is no longer connected for
communication with the cloud. Although the metadata may be sent
immediately “upon request,” that does not mean that at the time of the
“request” for the metadata, the metadata reflects any current information of
the home appliance. Indeed, Lee clearly contemplates that the stored
metadata may be used “in the future.” Ex. 1003 ¶ 133. In other words,
while the cloud-based server may immediately send the information, that
information might well have been obtained earlier and then kept in storage at
the server. It is speculative to assume that the cloud-based server queries the
appliance only after a request is received from the user. Petitioner points to
no such disclosure in Lee.
Furthermore, although Petitioner and Dr. Houh generally urge that
transmission of “stale” metadata would “not make sense,” that depends on
the meaning of “stale,” which Petitioner does not clarify. Metadata is not
“stale” simply because it is not up to the minute current. At least Petitioner
has not explained why it would be so. For instance, it is not explained why
the temperature within a refrigerator a minute ago should be deemed “stale”
PGR2019-00035
Patent 10,218,833 B2

26
and useless. Thus, receipt of non-stale metadata does not equate to current
communication connectivity.
We also have considered paragraph 224 of Lee’s disclosure, which
states: “When the terminal apparatus 160 received the information from the
data server 110, the user of the terminal apparatus 160 may monitor a
current state of the refrigerator and control temperature of the refrigerator
using the terminal apparatus 160.” Ex. 1003 ¶ 224. In the absence of any
disclosure that the server queries the appliance only upon request from the
user, and in light of Lee’s disclosure that the uploaded state information is
for future use, the reference to monitoring a current state of the refrigerator
is not sufficient to support Petitioner’s assertion that receiving state
information is itself an indication of present network connectivity of the
appliance. Just as we explained above why certain information from a short
moment ago may not be stale, certain information from a short moment ago
still may be deemed current. Something more is needed for Petitioner to
prove affirmative notification of present network connectivity of the
appliance.
Patent Owner’s declarant, Mr. Minoli, also acknowledged the
possibility that Lee’s metadata is not representative of the current state
information of a home appliance. See Ex. 2106 ¶¶ 97–103; Ex. 1148
(Minoli Deposition), 94:2–95:5. For example, Mr. Minoli testifies the
following: “the existence of metadata on the cloud is decoupled from
whether the appliance is communicably connected. At most, the existence
of metadata on the cloud-based data server 110 means that the appliance has
been communicably connected [to] the home gateway.” Ex. 2106 ¶ 100.
PGR2019-00035
Patent 10,218,833 B2

27
As is clear from the record, Dr. Houh and Mr. Minoli take opposing
views as to the nature of what a person of ordinary skill in the art would
have understood from the metadata supplied to Lee’s terminal apparatus
160. There is no challenge from either party as to the qualifications of either
declarant to give credible testimony in this proceeding. Nevertheless, for the
reasons discussed above, we are not satisfied that Dr. Houh’s testimony on
the issue of Lee’s metadata as constituting an indication of a grill’s
communicably connected status is supported by sufficient evidence of
record. We are also cognizant of Mr. Minoli’s testimony, discussed above,
that Lee’s disclosure does not convey that any appliance is communicably
connected to the cloud.
It is Petitioner’s burden to prove is proposition of unpatentability by a
preponderance of the evidence. 35 U.S.C. § 326(e) (2018); see 37 C.F.R.
§ 42.1(d) (2019). Satisfaction of that burden must be based on evidence of
record. See In re Magnum Oil Tools Int’l, Ltd., 829 F.3d at 1380–81. We
have considered the parties’ respective positions. Given (1) Lee’s ambiguous
disclosure as to the full purpose, content, and nature of its metadata, (2) the
conflicting testimony of the parties’ expert declarants, and (3) the absence of
other persuasive evidence supporting Petitioner’s contention, we conclude
that Petitioner has not met its burden on the record that is before us.
2. “providing a notification in the software application indicating
that the electronically-controlled wood-pellet grill is available to
receive instructions”
Claim 11 also requires that a “notification” is provided to a software
application indicating that wood-pellet grill “is available to receive
PGR2019-00035
Patent 10,218,833 B2

28
instructions.”6 Petitioner attempts to account for this requirement in a
manner similar to that discussed above with respect to the “is communicably
connected” aspect of claim 1.7
In particular, Petitioner points to Lee’s Figure 5 and its step 560
showing “the terminal apparatus 160 ‘display[ing] the states of the home
appliances 150 based on the . . . metadata’ received in step 555.” Pet. 54
(quoting Ex. 1103 ¶ 204).8 Petitioner further contends that “Lee explains
that ‘the states of the home appliances 150 may be output through a display
of the terminal apparatus 160.’” Id. Because, in Petitioner’s view, Lee
provides “broad description of state information,” such information includes
that Lee’s appliance is available to receive instructions. Id. (citing Ex. 1102
¶ 167). Petitioner urges that its view “is supported by the fact that the
displayed state information is a portion of the metadata received from the
cloud-based data server in step 555—i.e., the indication that the appliance is
communicably connected to the cloud.” Id. And, that “a skilled artisan

6 Claim 18 similarly requites a notification field “to further provide
notifications indicating that the electronically-controlled wood-pellet grill is
available to receive instructions.” Ex. 1101, 16:2–4.
7 Petitioner asserts that “Lee, Tucker, and Amer collectively disclose this
limitation.” Pet. 53. Tucker and Amer, however, are only cited to account
for additional disclosure of a “software application” and a “wood-pellet
grill.” Id. at 55. Thus, it is apparent that Petitioner relies on Lee’s
disclosure to meet the claim requirements pertaining to a notification that the
grill is “available to receive instructions.”
8 Pages 53 through 55 of the Petition present arguments addressing the
pertinent limitation as it appears in claim 11. Petitioner makes similar
arguments on pages 80 through 83 addressing the limitation as it appears in
claim 18.
PGR2019-00035
Patent 10,218,833 B2

29
would have understood that, once an appliance indicates that it is connected
to the cloud, the appliance is then ready to receive instructions from the user
via the cloud.” Id. (citing Ex. 1102 ¶ 168).
The testimony of Dr. Houh (Ex. 1102 ¶¶ 167–168)9 on which
Petitioner relies, however, provides little by the way of evidentiary citation
to the record to support the premise that Lee, itself, contemplates that its
metadata transmitted to terminal appliance 160 prompts display of a
notification that a home appliance is available to receive instructions. Patent
Owner challenges Petitioner’s and Dr. Houh’s positions on the basis that
their position that the displayed metadata “can include an indication that
Lee’s appliance is available to receive instructions” does not find sufficient
support in the record. PO Resp. 30–31 (quoting Pet. 54; Ex. 1102 ¶¶ 167,
203). Patent Owner also maintains that one of ordinary skill in the art
“reading Lee would not understand Lee’s ‘state information’ to include
information about whether the appliance is available to receive instructions.”
PO Resp. 31 (citing Ex. 2106 ¶ 105).
Having carefully reviewed the record at hand, we conclude that
Petitioner’s accounting for the requirement of (1) “providing a notification
in the software application indicating that the electronically-controlled
wood-pellet grill is available to receive instructions” as recited in claim 11,
and (2) “to further provide notifications indicating that the electronically-
controlled wood-pellet grill is available to receive instructions” as recited in
claim 18, suffers from the same or similar deficiencies as those discussed
above with respect to the indication that the grill is communicably

9 The referenced testimony pertains to claim 11. In conjunction with claim
18, Dr. Houh provides similar testimony. See 1102 ¶¶ 263–264.
PGR2019-00035
Patent 10,218,833 B2

30
connected. In that respect, we simply are not persuaded that Petitioner has
met its burden to show that a person of ordinary skill in the art would have
found those elements taught in the prior art of record.
3. Conclusion – Obviousness over Lee, Tucker, Henderson
Based on the record that developed during trial, we conclude that
Petitioner has not established by a preponderance of evidence that either
claims 11 or 18 would have been obvious over the teachings of Lee, Tucker,
Henderson, and Amer. Claims 12–17 and ultimately depend from claim 11
and claims 19–25 ultimately depend from claim 18. We also conclude that
Petitioner has not shown that those dependent claims would have been
obvious.
CONCLUSION
For the foregoing reasons, in view of the record that developed during
trial, we conclude that Petitioner has not shown by a preponderance of the
evidence that claims 11–25 of the ’833 patent are unpatentable.
In summary,
