    “The parties both argue that we should construe “non-contiguous hybrid arrangement” to mean “[a]n arrangement in which the first set of logic cells are interleaved or interlaced with the second set of logic cells.” Pet. 15; Prelim. Resp. 43. Petitioner supports its argument by pointing to the claim construction order from the HP litigation, which provides this construction for this term. Pet. 15 (citing Ex. 1010, 4 (construing non-contiguous hybrid arrangement)). Patent Owner supports its argument by citing to the written description and figures of the ’629 patent. Prelim. Resp. 43–46 (citations omitted). For example, Patent Owner cites Figure 4 of the challenged patent, and its accompanying text, and argues that Figure 4 illustrates that the “logic cells [are] interleaved in a manner that minimizes the space between heater arrays by forming a single linear array.” Id. at 44 (citing Ex. 1001, Fig. 4). The accompanying text teaches that “the magenta logic cells 440a–n may be interleaved between the cyan logic cells 420a–n in an alternating manner to form a single, linear hybrid cyan/magenta P-logic array 302.” Ex. 1001, 5:67–6:4; Prelim. Resp. 45 (citing same). The ’629 patent adds that “[b]ecause of this interlacing of cyan P-registers 420a–n and magenta P-registers 440a–n, neither the cyan P-registers 420a–n nor the magenta P-registers 440a–n remain contiguous,” and that “[f]or example, in F[igure] 4, the cyan logic cell 420b is followed by the magenta logic cell 440a instead of the next cyan logic cell 420c.” Ex. 1001, 6:10–15; Prelim. Resp. 45 (citing same). We have reviewed the parties’ arguments, and we adopt the parties’ proposed construction for this term. In addition, we determine that no express construction is needed for any other term for us to render our Decision on Institution. See, e.g., Nidec Motor Corp. v.

    “Upon review of the record and the parties’ arguments as a whole, we agree with Petitioner that Saito discloses a driver, as that term is used in claim 1 of the ’551 patent. First, our construction of “driver” is broad, constituting any “program, circuitry, or device used to power other programs, circuits, or devices.” And, consistent with the structure of claim 1 of the ’551 patent, this construction does not require that the identified circuit or device actually generate power, only provide power to another device or circuit. switch that turns on or off a power source. Rather, the circuit of Saito monitors the voltage provided at both node A 107 and node B 715 and, depending on the reported voltages, switches between voltage sources to provide power to the LEDs. In this way, the voltage applied to the LED circuit is maintained within a range of roughly 16 and 30 Volts, and the LEDs are driven for a prolonged period of time by capacitors 106 and 107, which Saito explains “cut[s] down the consumption of electric current” and results in more efficient use of power. Ex. 1008 ¶¶ 98–103. We find persuasive Dr. Baker’s testimony that one of ordinary skill in the art would have considered such a circuit to be a “driver,” as recited in claims 1 and 5 of the ’551 patent.

    “specification support its construction of “formed or mounted to” as encompassing indirect attachment to the substrate. Neither the plain claim language nor the specification requires the phosphor coating to be directly attached to the substrate. Limitation 1(c) recites, wherein the LED chips comprise a phosphor coating to produce a change in a color or a quality of light emitted from the LED chips, wherein the LED chips, the power connection leads, and the phosphor coating are formed or mounted to a flexible substrate that is sufficiently flexible to be formed into a cylindrical shape[.] Ex. 1001, 22:7–12 (emphasis added). The claim is inartfully written, as it requires the LEDs to comprise a phosphor coating but then separately recites that the LED chips and the phosphor coating are formed or mounted to the substrate. But Petitioner correctly explains that the plain meaning requires that “the LED chips comprise a phosphor coating” and that “the [same] phosphor coating” (included in the LED chips) is “formed or mounted to a flexible substrate.” Reply 2. In other words, the use of the term “the” before “phosphor coating” indicates reliance on the antecedent basis of “LED chips comprise a phosphor coating,” and thus the same coating of the LED chips is formed or mounted to the substrate. Logically, by including a phosphor coating with the LED chips, which are formed or mounted to the substrate, the coating of these chips is also indirectly formed or mounted to the substrate. Conversely, it would be illogical to conclude that the claim recites two phosphor coatings, one attached to the LED chips and another attached directly to the substrate, because the structure of the claim refers to a single phosphor coating of the LED chips. Even Patent Owner concedes that the claim encompasses the phosphor coating indirectly being mounted or attached to the substrate (in addition to being directly attached). PO Resp. 11 (“The ordinary English reading of the claim language does not encompass the phosphor coating only being indirectly attached to the substrate, instead, the language indicates that the coating is directly applied to the substrate.” (emphasis changed)), 13 (“the phosphor coating . . . is not merely attached to the substrate indirectly”).” slip op. at 10

    “After considering Patent Owner’s arguments, which we address below, we agree with Petitioner that the combination of Wojnarowski and Martin discloses this limitation and that a person of ordinary skill in the art would have been motivated to combine the references’ teachings in the manner asserted by Petitioner. Briefly, we summarize our findings, and then we address the parties’ arguments in more detail. First, we agree with Petitioner, and Patent Owner does not dispute, that Wojnarowski’s AC input voltage would have been converted to DC voltage in light of the bridge rectifier and capacitor disclosed by Wojnarowski. Pet. 25; Ex. 1002 ¶¶ 119– 20 (citing, e.g., Ex. 1005, 7:59–62, Fig. 24); PO Resp. 35–36 (acknowledging Wojnarowski discloses converting an AC input to a DC voltage). Second, we further agree with Petitioner, and Patent Owner does not dispute, that excessive current due to too few LEDs would have harmed Wojnarowski’s LEDs, and too small a current due to too many LEDs would be insufficient to power Wojnarowski’s LEDs. Pet. 26; Ex. 1002 ¶ 134; PO Resp. 48 (discussing, but not disputing, these assertions).13 Third, we agree that a POSITA would have recognized in view of Martin’s teachings and the knowledge of a skilled artisan that when configuring Wojnarowski’s device, the total forward voltage drop of the series-connected LEDs should approximately match the DC voltage output 13 Petitioner explains the relationship between voltage and current for the LEDs as follows: “the total voltage drop of the circuit would dictate the current drawn by the LED circuitry, which would have been known to be inversely proportional to the voltage.” Pet. 26 (citing Ex. 1002 ¶ 134). of Wojnarowski’s circuit. Pet. 26–27 (citing Ex. 1002 ¶¶ 132–38; Ex. 1008, Abstract (LED voltage “must be matched to the input source voltage”), ¶ 60 (“For AC or any other regularly varying input voltage, there is an additional requirement to direct drive voltage matching”)). For example, Martin teaches that “[t]he number of LEDs in the monolithic array may be selected to achieve a particular voltage drop across each device.” Ex. 1006 ¶ 22. Martin further explains, “[t]he voltage across each of the individual LEDs in the array is the line voltage divided by the number of LEDs in series,” and “[t]he number of LEDs is chosen such that the maximum voltage across each individual LED during the peak in the alternating current cycle is low enough so as not to damage the LEDs.” Id. The forward voltage drop across Martin’s 38 LEDs is about 171 V, which matches Martin’s AC input voltage peak of about 169.71 V. See id. (“At 120 RMS volts, the peak voltage will be about 180V [correction: 169.71 V],” and if the LEDs “can tolerate a maximum forward voltage of 4.5V, at least 38 LEDs connected in series are required.” (38 LEDs x 4.5 V = 171 V)); PO Resp. 41–42 (“While Martin references ‘about 180V,’ both parties agree that the correct value of the peak voltage Vp is 169.71 V.” (citing Ex. 1002 ¶ 127)).

This statute provides that “[a] petitioner in an inter partes review may request to cancel as unpatentable 1 or more claims of a patent only on a ground that could be raised under section 102 or 103 and only on the basis of prior art consisting of patents or printed publications.” § 311(b) (emphasis added). Patent Owner contends that Martin is not available as prior art under 35 U.S.C. § 311(b) because it is not a patent or printed publication and is only prior art under 35 U.S.C. § 102(e). PO Resp. 22. Patent Owner argues that documents are “printed publications” as of the date they become available to the public, and Martin became public on its publication date of October 21, 2004, after the February 25, 2004 priority date of the ’979 patent. Id. at 23. Patent Owner raises a similar argument for the Soules-II reference in Ground 6. Id. at 25– 26. Petitioner responds that the AIA framework permits the use of § 102(e) prior art in IPR proceedings, unlike formerly available covered business method review (CBM) proceedings, which restricted challenges to § 102(a) prior art. Reply 29. We agree. The statute governing the formerlyavailable CBM proceeding explicitly limits challenges based on “prior art that is described by section 102(a).” AIA § 18(a)(1)(C). In contrast, § 311(b) more broadly permits challenges “on the basis of prior art consisting of patents or printed publications.” The broader language in § 311(b) implies that unlike CBMs, IPRs are not limited to challenges solely under § 102(a) prior art. The parties cite to no Federal Circuit decisions that squarely address this issue. However, the Federal Circuit has applied § 102(e) patent application publication prior art in appeals from IPR proceedings. See, e.g., Purdue Pharma L.P. v. Iancu, 767 Fed. App’x 918, 920–21, 926 (Fed. Cir. 2019) (nonprecedential) (determining that a § 102(e) patent application publication was available as prior art in an IPR). The Board has also long permitted challenges based on patent application publications under § 102(e). See, e.g., Idle Free Sys., Inc. v. Bergstrom, Inc., IPR2012-00027, Paper 14 at 27 (PTAB Jan. 31, 2013) (instituting trial over § 102(e) ground based on a patent application publication).

    “Patent Owner contends there are “several problems” with Petitioner’s proposed definition. PO Resp. 11. In particular, Patent Owner contends the “and/or” qualifier and addition of “or a related field” could be read to allow an individual with no experience with LED devices to be a person of ordinary skill in the art. Id. Upon review of the parties’ arguments, the prior art of record, and the ’298 patent, we agree with Patent Owner that one of ordinary skill in the art would have had experience working with LEDs and/or LED circuit design.

    “C. Claim Construction In this proceeding, the claims of the ’298 patent are construed “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).” 37 C.F.R. § 42.100(b). Under that standard, the words of a claim are generally given their “ordinary and customary meaning,” which is the meaning the term would have had to a person of ordinary skill at the time of the invention in the context of the 1303, 1312–13 (Fed. Cir. 2005) (en banc). Neither party contends any terms of the ’298 patent require construction. Pet. 5–6; PO Resp. 12.

    “By its express language, the claim term “wirelessly” is best understood as “without the use of a wire.” We are directed to no disclosure in the written description or prosecution history that would contradict this conclusion or otherwise shed light on the meaning of this claim term. There is no dispute that capacitive coupling does not use a wire or any other form of direct contact to transmit power. Thus, the plain meaning of “wirelessly” encompasses capacitive coupling. This conclusion is supported 6,336,031 states that “[c]onnectionless (i.e., wireless) transmission of analog and digital signals has previously been accomplished using . . . [c]apacitive coupling.” Ex. 1131, 1:10–18. Likewise, U.S. Patent No. 6,988,026 describes a “power receiving system which receive[s] power wirelessly (inductively, through radio frequency energy transfer and/or capacitively).” Ex. 1133, 113:64–114:2. Mr. Credelle’s counter-testimony is not persuasive because he does not explain in any detail why one of ordinary skill in the art would not understand a capacitive coupling that transfers power to be a wireless system.

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

    “KSR instructs that “[t]he combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results.” KSR, 550 U.S. at 416. Here, Petitioner proposes to substitute one known method of transmitting power for another (an inductor in place of two capacitors), according to known methods (Logan), and Patent Owner does not dispute that the combination would yield a predictable result of wirelessly providing power from one device to another. This suggests that the proposed combination would have been obvious. Id. point to a specific problem discussed in Birrell for which Logan’s method of using inductive coupling would be a solution. See In re Heck, 699 F.2d 1331, 1333 (Fed. Cir. 1983) (“The use of patents as references is not limited to what the patentees describe as their own inventions or to the problems with which they are concerned. They are part of the literature of the art, relevant for all they contain.”) (internal quotations omitted). What the Petition must demonstrate is that there was some reason why one of ordinary skill in the art would have sought to combine the elements in the manner proposed. KSR, 550 U.S. at 418. The Petition provides multiple, persuasive reasons (discussed above) as to why one of ordinary skill in the art would have sought to use inductors, as disclosed in Logan, to wirelessly transmit power to a lighting device, such as that disclosed in Birrell.13 (d) Conclusion For the reasons set forth above, we find that Petitioner presents multiple, persuasive reasons as to why one of ordinary skill in the art would have sought to implement the wireless power transmission system of Logan in the lighting device of Birrell.” slip op. at 19

  • Expert testimonyPetitioner expert creditedDecided for petitioner

    “The implicit premise of Patent Owner’s argument is that Brcka discloses only failures and thus does not disclose “fault detection.” However, we credit the testimony of Dr. Shanfield that “[g]enerally you always need a fault to have a failure occur. So when there is a failure, a fault has occurred.” Ex. 2003, 74:6–11; see also Ex. 1003 ¶ 37 (“A fault is an abnormal tool condition, such as when a parameter strays beyond its acceptable boundary. Faults may lead to failure, which is the ‘termination of the ability of an item to perform a required function.’”) (internal citation omitted), 81 (“Machine failure, though, means that a fault condition existed requiring termination of the machine function upon the wafer.”). Thus, Brcka’s disclosure of analyzing machine failures is also, necessarily, a disclosure of a analyzing a fault. Accordingly, we find that Petitioner has established, by a preponderance of the evidence, that Brcka discloses “performing in a computer a fault detection analysis relating to processing of a workpiece.”” slip op. at 20

    “Petitioner cites to the embodiment depicted in Brcka’s Figure 4 as illustrating Brcka’s “fault detection analysis.” Pet. 32–33; see also Ex. 1003 ¶¶ 72–73. Figure 4 is a “flow diagram demonstrating operation of a learning system and [a] neural network model designed in accordance with at least one embodiment of [Brcka’s] invention.” Ex. 1005 ¶ 44. In step 415 of the operation disclosed in Figure 4, “a determination is made whether maintenance has been performed or a machine failure has occurred.” Id. ¶ 44, Fig. 4. If either of these things has happened, “a new reward value is calculated.” Id. In step 440, “a determination is made whether maintenance is needed.” Id. ¶ 45, Fig. 4. Thus, Brcka determines whether a failure has occurred, accounts for this determination by assigning a “reward value” (Fig. 4, step 425), and then decides whether maintenance is needed. On this record, the analysis reflected in these steps qualifies as a “fault detection analysis.” We recognize that Brcka’s fault detection analysis is used in a method that includes a predictive component. But, we do not find anything in the language of claim 1 that precludes performing the fault detection analysis as part of a predictive model. Indeed, the claim language requires only “performing . . . a fault detection analysis.” Moreover, the “fault detection” itself (i.e., Brcka’s step 415), as opposed to the analysis of the detected fault, is backward-looking, not predictive; it determines “whether . . . a machine failure has occurred.” Id. ¶ 44 (emphasis added).” slip op. at 16

    “Turning to our analysis, we start by addressing the interpretation of claim 9’s preamble, “[a]n LED lighting system.” Both parties brief the meaning of this preamble, but neither party addresses the threshold issue of whether the preamble is limiting. We note that “[g]enerally, a preamble is not limiting.” Summit 6, LLC v. Samsung Elecs. Co., 802 F.3d 1283, 1292 (Fed. Cir. 2015). However, among other exceptions to this general rule, our reviewing court has “repeatedly held a preamble limiting when it serves as antecedent basis for a term appearing in the body of a claim.” In re Fought, 941 F.3d 1175, 1178 (Fed.

    “Petitioner’s arguments are more persuasive. Dowling discloses mode switch 190, which, among other modes, can “strobe, that is, flash on and off,” LEDs in different colors. Ex. 1004 ¶¶ 47, 62. Dr. Neikirk testifies that this strobing action connects a red LED circuit to the AC voltage source, then disconnects it from the AC voltage source and connects a blue LED circuit to the AC voltage source. Ex. 1002 ¶ 39. Dr. Neikirk further testifies that Dowling discloses connecting and disconnecting the LED circuits to the AC voltage source via a controller that utilizes PWM to turn those circuits on and off. Ex. 1026 ¶ 27 (citing Ex. 1004, Figs. 1, 8, ¶¶ 38–43, 63). He further states, “[a]s I confirmed at my deposition, when a PWM transistor is off, it is off.” Id. (citing Ex. 2006, 33:17–25). Under the correct construction of “disconnected” set forth above, we find this evidence persuasive to show that Dowling discloses this limitation. Significantly, Dowling discloses, and Patent Owner does not dispute,8 that LEDs of 8 For the first time in the hearing, Patent Owner raised a new argument that “Petitioner [does not] point to any disclosure in Dowling that actually says that a mode turns an LED on and turns another LED circuit off.” E.g., Tr. 79:3–9. Relatedly, Patent Owner argues that Dowling’s “strobe mode” does not “cause[] some LED circuits to be connected and other LED circuits to be disconnected.” Id. at 80:21–81:2; see also id. at 81:3–83:12 (colloquy with counsel regarding the absence of a “strobe mode” discussion in the PO Response). These arguments came too late, and we do not consider them. See Dell Inc. v. Acceleron, LLC, 884 F.3d 1364 (Fed.

    “We agree with Petitioner that the combination of Dowling, Mueller, and Okuno would have rendered claim 14 obvious. We find persuasive Petitioner’s contention that it would have been obvious to implement the power conversion circuitry disclosed by Dowling for light bulb 180 using at least one transformer as taught by Mueller and Okuno. Pet. 34–35 (citing Ex. 1002 ¶ 85). We agree that Dowling already discloses power conversion circuitry for a light bulb, which converts a 120 volts AC input to a DC voltage of 5 or 12 volts. Id. at 29–30 (citing Ex. 1004 ¶ 58; Ex. 1002 ¶ 62). Specifically, Dowling describes a connection 70 for its light bulb that “may include a converter to convert received power to power that is useful,” for example, “an AC to DC converter to convert one-hundred twenty Volts at sixty Hertz into a direct current at a voltage of, for example, five Volts or twelve Volts.” Ex. 1004 ¶ 58; see also id. ¶ 63 (“A power converter can be used within the light bulb 180 to convert the received power . . . in the form of a variable amplitude AC signal . . . to the requisite power for the control circuitry and the LEDs . . . .”). We also credit Dr. Neikirk’s testimony that “a POSITA would have been motivated to investigate the known implementation details in the art regarding how to convert the AC power from a much higher voltage down to an appropriate direct current at a much lower voltage for driving LEDs, and been led to the teachings of Mueller and Okuno.” Ex. 1002 ¶ 62, quoted in Pet. 30. We further credit Dr. Neikirk’s testimony that “[a] POSITA would have been motivated to use a transformer and bridge rectifier as taught by Mueller and Okuno, and recognized the suitability of those components, for Dowling’s power conversion circuity in an Edison-mount lightbulb.” Id. ¶ 64 (citing Ex. 1004, Fig. 8, ¶¶ 62–63), quoted in Pet. 30. In other words, based on Dowling’s teachings of using power conversion circuitry in its light bulb, one of ordinary skill in the art would have looked to Okuno and recognized the suitability of a transformer for use as Dowling’s power conversion circuitry.

Reply Br. 1–2. “[I]nterpreting what is meant by a word in a claim is not to be confused with adding an extraneous limitation appearing in the specification, which is improper.” In re Cruciferous Sprout Litigation, 301 F.3d 1343, 1348 (Fed.

Harris Corp., 156 F.3d 1182, 1186 (Fed.

Advanced Cardiovascular Systems, Inc., 242 F.3d 1337, 1340 (Fed. Cir. 2001). Confining the scope of “capable of imparting solubility” to an unexpressed minimum solubility taken from one of the Specification’s embodiments crosses that line.
