      “5. Analysis Claim 1 recites “in a peripheral region of the image display region on the element substrate, a plurality of external circuit connection terminals, a plurality of main wiring lines . . . and peripheral driving circuits.” Ex. 1001, 21:55‒60. The plain and ordinary meaning of this phrase includes that the plurality of main wiring lines and peripheral driving circuits are formed on the element substrate. Claim 1 further recites, for the main wiring lines, “each having one end coupled to each of the plurality of external circuit connection terminals, and peripheral driving circuits coupled to the other ends of the main wiring lines.” Id. at 21:57‒59. The plain and ordinary meaning of this phrase is that each main wiring line is connected at one end to an external circuit connection terminal and, at the other end, to the peripheral driving circuits; this is how Petitioner addresses “a plurality of main wiring lines” as to this portion of claim 1 in accordance with the plain and ordinary meaning. Pet. 15 (“Figure 4 shows wiring lines coupled to the external connection terminals 102 at one end and coupled to peripheral circuits, including data line driving circuit 101, and scanning line driving circuit 104, at the other.”); see also Ex. 1002 ¶ 59.

      “Petitioner fails, however, to address the clause, “which is at least one of the plurality of main wiring lines,” and the implication that follows from the plain language of the claim. Id. Specifically, as set forth above, the “plurality of main wiring lines” are coupled at one end to peripheral circuits, and Petitioner provides no basis for the wiring 400 (LCCOM) to be coupled to any element identified by Petitioner as a peripheral circuit. Id. at 15‒17 (identifying data line driving circuit 101 and scanning line driving circuit 104 as peripheral circuits). Rather, Petitioner sets forth that wiring 400 (LCCOM) “supplies potential from the external input terminal 102 to the vertical conduction terminal 106 and then to the counter electrode 21 on the counter substrate 20.” Id. at 17 (citing Ex. 1005 ¶ 85, Figs. 3, 4; Ex. 1002 ¶¶ 63‒65). Further, to the extent Petitioner states that Muraide “discloses a counter electrode provided in the peripheral region on a counter substrate that is arranged to face the element substrate” (id. at 16 (citing Ex. 1005 ¶ 41; Ex. 1002 ¶¶ 60‒62)), Petitioner does not clearly identify the counter electrode as a peripheral circuit (id.) and, further, the counter electrode on the counter substrate is not a peripheral driving circuit on the element (“in a peripheral region of the image display region on the element substrate, . . . peripheral driving circuits” (emphasis added))). Accordingly, on this record, we determine that Petitioner fails to sufficiently establish “a counter electrode potential line that supplies counter electrode potential to the counter electrode, which is at least one of the plurality of main wiring lines.” Although Patent Owner did not clearly raise this particular issue, “[i]n an [inter partes review], the petitioner has the burden from the onset to show with particularity why the patent it challenges is unpatentable.” Harmonic, 815 F.3d at 1363 (citing 35 U.S.C. § 312(a)(3)).

Petitioner contends a person of ordinary skill in the art would have been motivated to use Kronberg’s watchdog to implement Moine’s receiver to achieve a predictable outcome, because watchdog timers were a well-known technique for detecting malfunctions, and the output of Kronberg’s watchdog could be provided to the switch 4 of Moine, to open and power down Moine’s circuit.

      “We interpret the term “heartbeat signals” as “periodic signals.” The term “heartbeat” appears only once in the in the specification outside of the claims: “the ‘heartbeats’ of the ping are set at a high rate, such as 100 or even 1000 per second.” Ex. 1001, 18:7–13. The disclosure of “the heartbeats” having a “rate” defined in “per second” terms indicates that they are periodic, as is generally recognized for heartbeats, i.e. human heartbeats. The term “heartbeat signals” appears in the challenged claims in conjunction with the detection of an anomaly (claim 12, “wherein the controller detects an anomaly in heartbeat signals from the remote unit”) and in conjunction with “skips” (claim 13, “wherein the anomaly includes skips of heartbeat signals”; claim 14, “when the anomaly includes a predetermined number of skips of the heartbeat signals”; claim 15, “when skips of the heartbeat signals are less than the predetermined number”). Accordingly, the heartbeat signals allow for the detection of an anomaly therein, indicating that they are typically predictable, and for the detection of skips of heartbeat signals, indicating that they are periodic. In view of the specification and the claims, and the parties’ arguments, we find that the plain and ordinary meaning of “heartbeat signals” is “periodic signals.”” slip op. at 12

      “Reply ignore the express statement in the Petition characterizing sensors 36 in Wedekind as “a source external to the building.” Sur-reply 2 (quoting Pet. 28), 3. Patent Owner also argues this is a new argument that we should disregard. Sur-Reply 2. We disagree. Although Patent Owner is correct that Petitioner contends Wedekind’s outside air temperature sensors 36 are a source external to the building, that is not the only argument Petitioner presents. In the Petition, Petitioner contends more generally that Wedekind’s outside air temperature sensors 36 “measure the outside air temperature.” Pet. 28. Petitioner also argues that Ehlers provides weather data including outside temperatures, and that the source of the data is a weather service provider that is external to the building. Pet. 32 (citing Ex. 1008, 9:53–54, 35:13–17). Petitioner further argues that it would have been obvious “to replace Wedekind’s outside temperature sensors 36 with receiving outside temperature data from a network connection,” as Ehlers teaches. Pet. 32. In view of this, we agree with, and are persuaded by, Petitioner’s argument that it does not rely only on Wedekind to meet the limitation that “the second data from the network connection is collected from a source external to the building.” Reply 10. Additionally, the presence of these arguments in the Petition undermines Patent Owner’s assertion that Petitioner is attempting to present new arguments in the Reply. Similarly, Petitioner acknowledges in the Petition that Wedekind does not expressly teach the second data is received from a network connection, and, therefore, relies on Ehlers’ disclosure of receiving data from a network connection. Pet. 30; Reply 11. Patent Owner does not dispute that Ehlers discloses receiving weather data from a network connection. See PO Resp. 15–28; Sur-reply 3–8.

The need for multiple sensors in Wedekind 5 We recognize Patent Owner argues that a person of ordinary skill in the art would not have been motivated to connect Wedekind’s outside air temperature sensors 36 to a network because it would “increase costs.” PO Resp. 23–24. Patent Owner, however, presents this argument before it addresses Petitioner’s proposed combination of Wedekind and Ehlers. See PO Resp. 23–24 (referring to cost increases first, and addressing the proposed combination of Wedekind and Ehlers in the next paragraph). Thus, Patent Owner’s cost argument does not appear to address Petitioner’s assertion regarding cost savings in view of the proposed combination. Nor does Patent Owner present evidence regarding, or explain adequately, what costs it is referring to, or how those costs would increase. PO Resp. 23–24; Ex. 2005 ¶ 61. By way of contrast, Petitioner’s arguments regarding cost savings are supported by the disclosure of Ehlers itself. Ex. 1008, 39:54–57. strengthens Petitioner’s argument that a person of ordinary skill in the art, in view of Ehlers’ teaching regarding avoiding the cost and effort of installing multiple sensors, would have had reason to modify Wedekind in view of Ehlers. Additionally, Patent Owner’s own declarant characterized Ehlers’ discussion of “lowering the cost of installation and ongoing maintenance” as “teach[ing] away from external sensors.” Ex. 1023, 58:7–18. These arguments and evidence undermine Patent Owner’s assertion that Petitioner failed to provide any analysis as to why a person of ordinary skill in the art would have modified Wedekind in view of Ehlers. Sur-reply 3–4; PO Resp. 25–28. Petitioner also argues, and provides evidence in the form of testimony from Dr. Shah demonstrating, that a person of ordinary skill in the art would have been able to modify Wedekind’s system by connecting Wedekind’s processing means to a network connection such as Ehlers’ phone input or communications link, and would have obtained predictable results. Pet. 33; Ex. 1002 ¶ 104. Patent Owner does not dispute this evidence. To the contrary, Patent Owner appears to concede that the proposed combination would work, although not as reliably as Wedekind’s hardwired system. PO Resp. 25–26. As a result, and in the absence of any evidence or argument suggesting otherwise, we credit Dr. Shah’s testimony. Furthermore, Ehlers teaches, in connection with providing data obtained from a weather service provider over a network, that “[t]he data may be provided at regular intervals and be sufficiently localized for acceptable accuracy.” Ex. 1008, 9:58–60. This statement from Ehlers itself undermines Patent Owner’s arguments regarding alleged problems with transmitting data over networks and insufficient accuracy, including Patent Owner’s argument that Wedekind teaches away from the approach used by Ehlers. PO Resp. 25–28. Nevertheless, even if we were to give Patent Owner the full credit of its arguments regarding unreliable transmission of data over networks and data obtained from weather service providers being less useful than data obtained from sensors at a specific structure, obviousness “does not require that the motivation be the best option, only that it be a suitable option from which the prior art did not teach away.” PAR Pharm., Inc. v. TWI Pharm., Inc., 773 F.3d 1186, 1197-98 (Fed. Cir. 2014). As discussed above, Petitioner’s evidence and arguments demonstrate that using Ehlers’ network to transmit temperature data was at least a suitable option. For all of the foregoing reasons, we determine Petitioner has demonstrated persuasively that a person of ordinary skill in the art would have had reason to modify Wedekind in view of Ehlers, and would have had a reasonable expectation of success in doing so. iii.” slip op. at 25

      “On this complete record, we find that Petitioner’s testing does not sufficiently demonstrate that Wikey inherently discloses nanobubbles. Pet. 22–29. Petitioner apparently had the ability to test for the express disclosure of nanobubbles in its Wikey-based apparatus, but did not do so. Sur-Reply 2–3.

Id. However, Petitioner’s expert acknowledged that he did not do any testing that would determine whether nanobubbles were formed. Id. at 7 (citing Ex. 2172, 70:1–4). Petitioner’s reliance on milkiness and supersaturation to demonstrate the presence of nanobubbles is also unsupported. Petitioner argues that milky appearance equals supersaturation (Reply 9 (citing Ex. 1101, 9:38– 50)), and also that milky appearance equals nanobubbles (id.

PO Resp. 25–26; Sur-Reply 6–7; see also Tr. 13:24–26 (Petitioner’s counsel agreeing that “you can have supersaturation without milkiness”).

In that regard, a petition for inter partes review must identify how the challenged claims are unpatentable, and must specify where each element of the claim is found in the relied-upon prior art. 37 C.F.R. § 42.104(b); see also 35 U.S.C. § 312(a)(3) (a petition must identify “with particularity, each claim challenged, the grounds on which the challenge to each claim is based, and the evidence that supports the grounds for challenge to each claim”).

      “On this record, we determine that the control system limitations sufficiently connote structure and are not subject to means-plus-function construction. See Williamson, 792 F.3d at 1349 (stating the determination of whether a limitation is a means-plus-function term “subject to the strictures of § 112, para. 6” is not based merely on the presence or absence of the word “means” but on whether “the words of the claim are understood by persons of ordinary skill in the art to have a sufficiently definite meaning as the name for structure”). As to Petitioner’s argument that Patent Owner only demonstrates support for “controls” and “controllers” being known in the art and not for a “system,” as the claims recite (Reply 11–12), we determine that there is no meaningful distinction because the controls or controllers disclosed in the ’970 patent are necessarily included in systems with other known elements to control temperature. Further, the disclosure of exemplary apparatus in the specification, including disclosure incorporated by reference (Ex. 1101, 1:58–61), supports that temperature control systems are known structures/apparatuses, and Petitioner fails to establish that they are not (see generally Pet.; Reply). In sum, we determine the control system limitations are terms that persons of ordinary skill in the art would have understood to have a sufficiently definite meaning as the name for structures of a broad category of systems known to those of skill in the art. The breadth and diversity of the structures/apparatuses ordinarily skilled artisans would have understood to be included within the meaning of the terms do not subject the terms to means-plus-function construction.

      “Regarding Patent Owner’s first argument, we find that Finegan sufficiently discloses thermally isolated wells and insulative gaps. Finegan’s wells are either thermally isolated as a result of their relative orientation (Pet. 31 (citing annotated Finegan Fig. 7)), or as a result of the insulation or insulative air gap (Pet. 29–31 (citing annotated Finegan Figs. 4, 7)). Finegan’s flanges, whether frosted or not, are “part of the well and must themselves be thermally isolated from their surroundings to facilitate frost formation,” and “the inclusion of the flanges does not defeat the well’s thermal isolation.” Reply 13; Ex. 1103 ¶¶ 294–297 (Dr. Homan’s testimony). Petitioner also demonstrates that Finegan’s insulation material would reduce heat transfer. Ex. 1149 ¶¶ 84–85 (Dr. Homan’s testimony that Finegan’s insulation material and insulation tape reduce heat transfer). Finegan’s insulation “extends over most of the well and the thermally-conductive material (38), to insulate the well.” Reply 13 (citing Ex. 1149 ¶ 84; Ex. 1105, 7:22–26, Fig. 4). Although we agree with Patent Owner that Finegan states that there is a “need to provide for a food service table or buffet that employs a shallow pan for use in both hot and cold service conditions while still providing sufficient frosting of the top surface” (Ex. 1105, 2:11–13), Petitioner has demonstrated that Finegan’s thermal isolation and insulation would not defeat this objective. Reply 13–14. Regarding Patent Owner’s second argument, we refer to our claim construction to find that Finegan teaches wells in a single frame. Because, under our construction, a well includes at least the interior well walls and exterior well walls (if present), and a frame refers to a “rigid supporting structure,” we find that Petitioner persuasively demonstrates that Finegan teaches wells in a single frame. Pet. 26–27, 29–31. We disagree that “skilled artisans would view the two apparatuses (10) in Figure 7 of Finegan to be independent pieces of equipment and thus not a module with wells bound by a single frame” and that “Finegan does not teach wells in a single frame” because the pans are separated by what Patent Owner argues is an “indeterminate distance of countertop.” PO Resp. 32. As discussed above, we decline to adopt Patent Owner’s claim construction for “a frame.” Accordingly, we find that, under our claim constructions, Petitioner demonstrates that Finegan’s countertop 14 and side walls housing its wells 18 meet the limitations of the challenged claims, particularly those that require an arrangement between the frame and the wells (i.e. claims 14, 23, and 25). Reply 14–15, 17 (citing Ex. 1105, annotated Figs. 1, 7; Ex. 1149 ¶ 101); see also Ex. 2050, 10–11 (finding unfounded the district court’s determination “that Finegan’s Figure 7 only discloses a single pan in each of two separate modules” and determining that Figure 7 “discloses a single ‘apparatus 10’ with two wells 18A and 18B . . . . Those wells are shown within a single countertop 14.”). Additionally, we disagree with Patent Owner’s characterization of Dr. Homan’s testimony as admitting that Finegan’s pans/wells are separate modules. PO Resp. 30–32 (citing Ex. 1130, 241:24–242:3, 217:20–24, 240:5–14). A fair reading of Dr. Homan’s testimony indicates that he was referring to “wells,” despite counsel using the term “modules,” ultimately supporting Petitioner’s position that Finegan discloses two wells in a single frame. Reply 15–16 (citing Ex. 1130, 241:15–242:2). Regarding Patent Owner’s third argument, and referring to our claim construction, we find that Finegan teaches the control system limitations. Although we do not find these terms to be subject to means-plus-function construction, we nevertheless find sufficient Petitioner’s mapping of these limitations to the structures in Finegan performing the functions of the control system limitations. See, e.g., Pet. 31–32 (regarding claim 1.c.1, referring to Finegan Fig. 7 to map PLC 80 connected to heating elements 78 (via switches 94) and valving 90 for controlling refrigerant flow from condensing unit 118 to cooling coils 32, and using user interface 96 and temperature sensors 82A). Petitioner persuasively argues that Finegan’s PLC (programmable logic controller) 80 and user interface 96 meet the control system limitations: “Both Finegan’s global control and the ‘970 patent’s individual controls perform this function [of independently controlling the wells’ temperatures] in the same way, by connecting the electrical resistance heating elements to an electrical power source and by operating valving to control the flow of refrigerant.” Reply 20 (citing Ex. 1101: 4:49–52, 4:56–63; Ex. 1105, 9:27–11:28); Pet. 32–33.” slip op. at 29

Id. at 52 (citing Ex. 1103 ¶¶ 279–282). Patent Owner’s argument that Finegan does not disclose an insulative gap and that its insulation does not meet the limitations of the challenged claims argues against Finegan individually, rather than against the Finegan-Safyan combination. See In re Merck & Co., 800 F.2d 1091, 1097 (Fed. Cir. 1986) (“Non-obviousness cannot be established by attacking references individually where the rejection is based upon the teachings of a combination of references.”).

Pet. 51–53 (relying on Ex. 1103 ¶¶ 276–282); Reply 22–23. Regarding claim 9, we find that Petitioner provides adequate motivation as to why one of ordinary skill in the art “would have minimized the distance between wells.” Pet. 53–54; Ex. 1149 ¶ 124–126. We credit Petitioner’s reliance on references and evidence supporting its assertion that one of ordinary skill in the art “would have located Finegan’s wells as close together as needed (e.g., three inches or less)” to “meet size restrictions for a compact space-saving design.” Pet. 56 (citing Ex. 1103 ¶¶ 298–299). We disagree that “Finegan’s frost top would be destroyed” (PO Resp. 43) by this combination, because spacing “as small as a fraction of an inch between the flanges of adjacent wells would ensure thermal isolation of the wells and that a cooled flange would form frost.” Pet. 56 (citing Ex. 1103 ¶297).” slip op. at 36

The clearest expression of a motivation to combine set forth in association with the ground, as applied to the independent claims, is that “a [person of ordinary skill in the art] would have been guided to look at leak detection systems, such as that disclosed in the Hunaidi Article,” because “[t]he Hunaidi Patent explains that ‘[t]he proposed method is easy to implement, for example, in conjunction with routine leak detection surveys.’” Pet. 38 (citing Ex. 1003, 3:35–36; Ex. 1004, Abstract, 7; Ex. 1002 ¶ 77). The difficulty with this is that the Hunaidi Patent itself already discloses what appears to be routine leak detection surveys, and it is thus not apparent what benefit would be obtained by this combination to motivate the skilled artisan to combine the teachings. Cf. Belden v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015) (“[O]bviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed invention.”). As to further reasons set forth for the combination, as applied to claims 1 and 8, these are grounded on shortcomings in “the Hunaidi Article . . . not disclos[ing] an equation for velocity” or go to the obviousness of modifications to the Hunaidi Patent itself independent of the Hunaidi Article’s teachings. Id. at 38–40 (citing Ex. 1001, 7:1–12; Ex. 1002 ¶¶ 63–71, 80–86; Ex. 1003, 2:57–3:11, 1:8–11, claims 1& 11).” slip op. at 19

    • Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityNot reached

      “1. Printed Publication Status of the Hunaidi Article In an inter partes review, the petitioner bears the burden of establishing by a preponderance of the evidence that a particular document is a printed publication. Nobel Biocare Servs. AG v. Instradent USA, Inc., 903 F.3d 1365, 1375 (Fed. Cir. 2018) (citing Medtronic, Inc. v. Barry, 891 F.3d 1368, 1380 (Fed. Cir. 2018)). Whether a reference qualifies as a “printed publication” is a legal conclusion based on underlying factual findings, including whether the reference was publicly accessible. Id.; see also In re Wyer, 655 F.2d 221, 227 (CCPA 1981) (a party asserting a reference as a prior art printed publication should provide sufficient proof of accessibility). Petitioner contends that the Hunaidi Article is prior art under 35 U.S.C. § 102(a) and (b). Pet. 35. Petitioner fails, however, to set forth any basis for the document to be a printed publication, that is, for its public accessibility. See Pet. Similarly, there is no testimony by Dr. Wilkens relevant to this issue. See Ex. 1002. Further, on this record, there is neither argument nor testimony as to the authenticity of what Petitioner has filed as the Hunaidi Article (Exhibit 1004).” slip op. at 18

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “Petitioner contends that a person of ordinary skill in the art “is a person with a degree in mechanical engineering, chemical engineering, or physics, and approximately three to five years of combined work experience and/or graduate work in fluid dynamics.” Pet. 10 (citing Ex. 1002 ¶¶ 24– 25). As Patent Owner has waived its preliminary response, Petitioner’s contended level of ordinary skill stands uncontested. On this record, we find Petitioner’s definition of the level of ordinary skill reasonable and, therefore, adopt it for the purposes of this Decision.” slip op. at 8

      “Institution of an inter partes review is authorized by statute when “the information presented in the petition . . . shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314(a) (2018). Upon consideration of the Petition and the evidence of record, we determine that Petitioner has established a reasonable likelihood that it would prevail in showing the unpatentability of at least one claim challenged in the Petition. Accordingly, we institute an inter partes review of all claims and all grounds asserted in the Petition.1” slip op. at 2

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededOther

      “A. Claim Construction Petitioner contends the claim term “the location controller,” as recited in claim 1 of the ’321 patent, should be construed to mean “the local controller,” because the term “location controller” has no apparent antecedent basis in the claim and does not appear anywhere in the 3 The Leahy-Smith America Invents Act (“AIA”) included revisions to 35 U.S.C. §§ 102 and 103 that became effective on March 16, 2013. Because the ’321 patent issued from an application filed before March 16, 2013, we apply the pre-AIA versions of the statutory bases for unpatentability. 4 FR Patent Application Publication No. 2894401 A1 to Moine, published June 8, 2007 (Ex. 1005). 5 US Patent No. 5,054,023 to Kronberg, issued October 1, 1991 (Ex. 1006). 6 US Patent No. 8,531,055 B2 to Adest et al., issued September 10, 2013 (Ex. 1007). specification of the ’321 patent, and further in light of the fact that claim 1 first recites “a local controller.” Pet. 10–11. Other than the aforementioned claim term, Petitioner states no express constructions of the claims are necessary to assess whether the prior art reads on the challenged claims. Id. at 9 (citing Ex. 1002 ¶ 35). Having considered Petitioner’s argument, we can reach a determination of the reasonable likelihood of proving unpatentability of the challenged claims without explicitly construing any claim terms at this stage of the proceeding. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))).” slip op. at 7

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “Petitioner argues a person of ordinary skill in the art at the time of the invention “would have had a bachelor’s degree or similar degree in electrical engineering and one year of experience in the design of solar power systems, power control systems, and/or power safety systems.” Pet. 3–4 (citing Ex. 1002 ¶ 17). For purposes of this Decision, we adopt Petitioner’s proposal regarding the level of ordinary skill in the art. Based on our review of the ’321 patent and the asserted prior art, we determine that Petitioner’s definition comports with the qualifications a person would have needed to understand and implement the teachings of the ’321 patent and prior art.” slip op. at 8

      “Having reviewed Petitioner’s undisputed evidence and argument regarding claim 1, we find that Petitioner has demonstrated sufficiently that Moine discloses all of the limitations of claim 1. Thus, we are persuaded Petitioner has established a reasonable likelihood of prevailing on its anticipation challenge with respect to claim 1.” slip op. at 14
