Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019). As such, we proceed in line with Federal Circuit case law, which “prescribes—deciding only the issues necessary to resolve the dispute before it.” Nichia Corp. v. DSS, Inc., No. 2022-1704, 2023 WL 7211097, at *3 (Fed. Cir. Nov. 2, 2023) (citing Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017)). The Federal Circuit has long recognized that “[c]laim construction is a matter of resolution of disputed meanings and technical scope” and that claim construction may be required in an obviousness context “when the meaning or scope of technical terms and words of art is unclear and in dispute and requires resolution in order to determine obviousness.” U.S. Surgical Corp. v. Ethicon, Inc., 103 F.3d 1554, 1568 (Fed. Cir. 1997). In order to determine whether Petitioner’s obviousness grounds meet their required burden of proof, we need not expressly state the full scope of this claim term. Thus, we are within our authority to proffer a construction that determines the scope of a claim term in a manner sufficient to determine whether the asserted art teaches the claim. In other words, there may be other ways to meet the disputed limitation, but for the purposes of our Decision, it is proper to expressly determine a claim term’s scope only as much as is required to resolve the disputed issues before us.” slip op. at 17

“declaration addresses the Patent Owner Response and is relevant to the issues at hand. We start with an important observation: claim 18 (the only independent claim at issue) is an apparatus claim; the claim is directed to a “semiconductor light source.” Ex. 1001, 9:52, EPRC 1:32. One requirement of this apparatus is that it comprise “a semiconductor chip” (id. at 9:66) where “said semiconductor chip is a light emitting diode (LED) chip EPRC, 1:34–36. As we explain when addressing claim construction, infra, we adopt Patent Owner’s proposed construction (Resp. 14) of “said semiconductor chip is a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as referring to “a semiconductor LED chip capable of emitting light greater than about 40 milliwatts.” See Section III.D, infra (emphasis added). Because of these recitations, Petitioner bears the burden of establishing that the prior art teaches or suggests a semiconductor LED chip “capable of emitting light greater than about 40 milliwatts.” As explained herein, we determine that in the Petition, Petitioner met this burden by establishing by a preponderance of the evidence that the Krames reference teaches an LED chip that has this capability. Pet. 53 (quoting Ex. 1008, 10). Notably, claim 18 does not require actual operation of anything at greater than 40 milliwatts because claim 21 is not a method claim.

“Delaware held, with respect to related U.S. Patent 6,465,961, construed “a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as “at least one LED chip is capable of emitting light greater than about 40 milliwatts.” Resp. 14 (citing Ex. 1024, 15–18). Petitioner responds that the phrase “needs no construction” and that Petitioner’s grounds meet this construction. Reply 1. We note that the language of claim 18 does not precisely match the language the District Court considered, it is substantively the same. The record supports a construction very similar to the construction the District Court adopts, and we reference the District Court’s reasoning. Ex. 1024, 15– 18. We, thus, construe claim 18’s recitation that “said semiconductor chip is a light emitting diode (LED) chip configured to output light at greater than about 40 milliwatts” as referring to “a semiconductor LED chip that is capable of emitting light greater than about 40 milliwatts.” It is unnecessary to construe any other claim terms in this Decision because none of the parties’ disputes turn on the meaning of other terms.

- Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedReference is prior artDecided for petitioner
“The facts above are evidence of the Krames reference’s publication as of June 29, 2000, because the facts tend to make the Krames reference’s publication as of June 29, 2000, more probable than it would be without the evidence. See Fed. R. Evid. 401(a) (defining evidence as relevant “if it has any tendency to make a fact more or less probable than it would be without the evidence”). The evidence is sufficient to support publication. Meanwhile, no evidence of record suggests that Krames was not a printed publication as of June 29, 2000. Thus, a preponderance of the evidence supports Krames’s prior art status. Patent Owner argues that Ms. Watters “never establishes a firm date when Krames was purportedly available to the relevant public.” Resp. 21. Patent Owner bases this argument by taking a tortured reading of Ms. Watters’s statement that “[m]embers of the interested public could locate a copy of [the Proceedings] on or after June 29, 2000, the date it was catalogued.” Id. (quoting Ex. 1020, 3); see also Sur-Reply 12–13. The best understanding of Ms. Watters’s statement, in view of the context of Ms. Watters explaining the library’s cataloguing process, is that a member of the interested public had two options: the person could choose to locate the Proceedings on June 29, 2000, or the person could choose to locate the Proceedings after June 29, 2000.

“In the Reply, Petitioner uses the Krames declaration (Ex. 1028) to argue, for example, that a person of ordinary skill in the art would have used a lower amperage than the 1.5 A dc that Patent Owner’s Response focuses on. Reply 8 (citing Ex. 1028 ¶ 22). This use of the Krames declaration is timely because it responds to an argument Patent Owner makes in the Patent Owner Response. 37 C.F.R. § 42.23(b) (“A reply may only respond to arguments raised in . . . patent owner response.”). As to relevancy and whether the Krames declaration is applicable to the facts of this case, the issues at hand are (1) whether or not a person having ordinary skill would have had reason to use the Krames LED with Begemann with a reasonable expectation of success and (2) whether or not the Krames LED is capable of outputting light at greater than about 40 milliwatts. Again, we emphasize that claim 21 does not recite a method where the LED within the recited semiconductor light source actually outputs greater than about 40 milliwatts. The Krames declaration is relevant to the facts of this case because the declaration has bearing on whether or not a person of ordinary skill in the art would have combined the Krames reference’s LED with Begemann’s lightbulb design. See, e.g., Ex. 1028 ¶ 22. Patent Owner argues that evidence must be relevant to motivation to combine “an LED chip from the Krames article (operating at 1.5 amps to produce 170 milliwatts of output)” but claim 21 has no “operating at 1.5 amps to produce 170 milliwatts of output” requirement. What is relevant is that Krames discloses a single chip that has the capability of outputting more or less light depending on operating conditions. Pet. Opp. 3; see also Ex. 1008, 8 (providing that Figure 12 of the Krames reference is described as illustrating “[l]ight output vs. current characteristic of a blue … 1x1 mm2 AlGaInN LED in a power package, compared to a conventional AlGaInN LED in a 5 mm lamp a package”). Because claim 21 does not require actually running the recited LED at any particular wattage or amperage, it is appropriate for the Krames declaration to rebut Patent Owner’s argument that a person of ordinary skill would not have considered using the Krames LED with Begemann at high amperage by explaining that a person of ordinary skill in the art would have considered using the exact same Krames LED with Begemann at a low amperage instead and that at this lower amperage the Krames LED would generate an amount of heat that would be easily dissipated by Begemann’s lamp while still providing an optical output of “greater than about 40 milliwatts” as recited by claim 21. Ex. 1028 ¶¶ 23–24 (citing Ex. 1008, 8). The fact that the Krames LED is configured to run at the high amperage if desired for a different application does not negate the rationale for combining the Krames LED to run at a lower amperage.” slip op. at 14

The Figure 1 apparatus, at the location of the purple oval, merely conveys a strobe signal (gwlstrbuf 20) on a line without substantially changing that signal. Id. Fig. 1. The Figure 2 apparatus, however, illustrates main amp strobe 60 generating output signal 88 by delaying the gwlstrbuf signal output by buffer 58. Id. at 4:6–9, Fig. 2. Given the context of the ’429 patent specification, we decline to construe “main amplifier strobe” in a manner that would fail to distinguish Figure 2’s main amplifier strobe from Figure 1’s unlabeled strobe-carrying line (identified with a purple oval above). See id. (identifying main amp strobe 60 as a “main amplifier strobe circuit 60”). If Figure 2’s identification of a “main amplifier strobe 60” is to be distinguishable from Figure 1’s lack of any identified main amplifier strobe 60, the main amplifier strobe has to be more than just a mere strobe signal or line that carries a strobe signal. The ’429 patent specification explains that “first main amplifier strobe circuit 60 delays the rising edge of the output of the buffer 58” to “ensure[] that the local amplifiers 82, 84, 86 stay on until the main amplifier 108 is on.” Id. at 4:6–9. While we decline to import this exact functionality from the specification into claim 1’s “main amplifier strobe,” based on the discussion above, the main amplifier strobe must affect the transmitted signal and it must affect the signal consistent with the word “strobe.” See Phillips, 415 F.3d at 1323 (“[A]lthough the specification often describes very specific embodiments of the invention, we have repeatedly warned against confining the claims to those embodiments.”).” slip op. at 13

Resp. 10; Ex. 2003, 3 (ordinary dictionary defining toward as “in the direction of” or, alternatively, as “along a course leading to”). Patent Owner argues that the ’976 patent describes embodiments supporting Patent Owner’s construction of “toward,” but directs us to no disclosure that requires “aiming.” To the contrary, the ’976 patent suggests that liquid moves “toward” something such as an end point so long as it advances along a path leading to the end point. Reply 1–4 (Petitioner collecting examples). For example, ’976 patent Figures 5 and 6 illustrate fluid taking a spiral flow pattern to outlet zone 174. The specification explains that the liquid takes a “curvilinear path . . . as it moves from the inlet 172 toward the outlet zone 174.” Ex. 1001, 10:50–55; see also Ex. 1015 ¶¶ 8–16 (Dr. Morse providing testimony regarding this and other ’976 patent embodiments). Thus, contrary to Patent Owner’s position, the specification uses the word “toward” to describe liquid that moves in the direction of the outlet––without reference to aiming––and even where the liquid’s movement encounters obstacles or otherwise fails to travel in a straight line to the outlet. We agree with Petitioner that “‘aimed’ is found nowhere in the intrinsic evidence and is contrary to the specification” of the ’976 patent. Reply 1.

“Based on the record before us, the preponderance of the evidence supports Petitioner’s position. King is concerned with delivering small particles to a patient: King states, for example, that an object of its invention is to “deliver to the patient essentially the same particle size distribution of the aerosol mist that originates from the nebulizer itself.” Ex. 1006 2:19–22; see also id. at [57] (stating that its apparatus delivers medication “in essentially the same particle size distribution of the aerosol mist”); 1:7–10 (stating that invention “delivers a mist of properly sized aerosol particles”); 1:60–65 (stating that invention “functions in a manner to assure that the medicament particles delivered to the patient will be of optimum size”). King states that in “this latest form of the invention this important baffle means comprises a generally spiral-shaped wall 100 (Fig. 20).” Id. at 6:20– 22. A person of ordinary skill in the art would have understood that design of the passage, through which aerosolized particles pass, will affect the size of output particles. Ex. 1003 ¶ 60; Ex. 1004 ¶ 27 (teaching that, for example, “tight bends” may be use to separate small airborne particles from big particles). We find that a person of ordinary skill in the art would have recognized that the spiral structure of King’s passage is an example of a “tight bend” (as referenced by Rosener) that can help control what size of particle progresses through the entire passage. Ex. 1006 6:16–22 (explaining that “this important baffle means comprises a generally spiral-shaped wall 100” and serves to “provid[e] a circuitous fluid flow path through the first chamber”)8; Ex. 1003 ¶¶ 56–61. A person of ordinary skill in the art’s use of a spiral structure, as taught by King, to further control particle size via tight bends, as taught by Rosener, would have been obvious because it would have been a “predictable use of a prior art elements according to their established function.” KSR Int’l, Co. v. Teleflex Inc., 550 U.S. 398, 417 (2007). Rather than a spiral disrupting Rosener’s separation as Patent Owner argues, the combined teachings of Rosener and King suggest that King’s spiral would assist in achieving separation and particle size control (as Rosener and King teach). Dr. Morse’s testimony is credible in this regard and supports our findings and conclusion along with the references themselves. Ex. 1003 ¶¶ 54–56.

- BurdenNot shown unpatentable
“Ultimately, to determine whether Rosener’s suggested tortuous passage is a structure capable performing the functionality of claims 7 and 16, we would need to determine that, because of Rosener’s tortuous passage, liquid would take more time to leak when the device is upended than if the tortuous passage was not present. The record before us, however, does not adequately support such a finding. Here again, the paucity of information provided by Petitioner, who bears the burden of showing unpatentability, tips against a conclusion that these claims are proven unpatentable. Although tight bends and corners might make the flow take longer to leak from the cartridge (as Petitioner urges at Reply 4–6), Petitioner does not establish that this is the case and, moreover, does not establish that it is not the case that the tight bends and corners might make the liquid take less time to leak from the cartridge. As Patent Owner argues, where a channel narrows in a direction of flow, a fluid’s speed may increase in accordance with Bernoulli’s principle. Sur-Reply 7–8.10 This principle is evidenced by the Svoboda reference, which explains that gas will travel faster through the “necked down portion 29” of its venturi tube. Ex. 1008, 4:4–8, Fig. 1, 2 (illustrating necked down portion 29). Accordingly, the record is unclear as to whether the tight bends and corners would speed up or slow down the flow of liquid from the cartridge. Additionally, Rosener does not refer to its tortuous passage as preventing leaking, and if the tortuous passage were capable of doing so, it is unclear why the valve would be necessary. See 10 The record also lacks evidence regarding to what extent other factors such as fluid viscosity, pressure differentials, and friction losses could potentially also affect flow speed. This lack of evidence, again, underscores Petitioner’s failure to meet its burden to show unpatentability of these claims. generally Ex. 1004; see also Ex. 2005 ¶ 68 (Dr. Mello’s written testimony on point). In any event, for reasons explained by Patent Owner, Petitioner’s analysis regarding the path and speed of liquid flow when Rosener’s device is upended is insufficient to support the unpatentability of claims 7 and 16 (Sur-Reply 1–18), at least because Petitioner fails to take account of leakage through orifice 401 or because of Rosener’s express need for a valve to provide for a device that “may be inverted without causing the fragrance oil to pour out” (id. at 12). See Ex. 1004 Fig. 2D (illustrating position of orifice 401), ¶ 33 (describing Rosener’s valve); see also Resp. 11–17 (Patent Owner’s arguments); Pet. 29–30, 33; Reply 4–6 (Petitioner’s analysis).” slip op. at 37

See IGT v. Bally Gaming Int’l, Inc., 659 F.3d 1109, 1117 (Fed. Cir. 2011) (“We caution that claim language must be construed in the context of the claim in which it appears. Extracting a single word from a claim divorced from the surrounding limitations can lead construction astray. Claim language must be construed in the claim in which it appears.” (emphasis added)). The selection clauses recited in these claims are plainly different on the face of the claims when considering the material differences in the claim language set forth above. According the same meaning to the limitations that recite “select . . . based on” indicators, “select . . . when” certain conditions are met, and “select . . . out of a group” of values would be improper because it would blur the material differences in the claim language recited expressly in the claims. Instead, we interpret the selection clauses recited in the challenged claims “in the context of the particular claim in which the disputed term appears” and “in the context of the entire patent, including the specification.” Phillips, 415 F.3d at 1313.

Claim 13 recites “selecting, by the control circuit, a value of a control signal based on the mode indicator and on the leakage indicator.” In our view, the plain meaning of this limitation is clear on the face of the claim—a value of a control signal is selected based on two indicators, the mode indicator and the leakage indicator.” slip op. at 14

“Tr. 47:7–23. Because the output of Kim’s NAND gates will be different depending on the value of Kim’s memory cells C1–CN allowed to “pass through,” we agree with Petitioner that the value of Kim’s memory cells C1– CN (the claimed “leakage indicator”) “plays a role” in deciding what the output of Kim’s NAND gates (the claimed “value of the control signal”) will be. Moreover, Patent Owner acknowledged that the output of Kim’s NAND gate is determined based on the inputs to the NAND gates (i.e., the sleep signal input and the memory cell signal input). JUDGE CHUNG: But, knowing a little bit about how a NAND gate works, isn’t it the case that the input to the NAND gates, G1 through GN, with the input of the sleep signal and the C1 through CN signal, isn’t it the case that input to the NAND gate determines what the output is? MS. ZHONG: Okay. So any logic gate, the output will depend on the input. That’s for sure. Tr. 44:18–25; but see id. at 45:3–10 (stating that even if the “output is in control of the input, . . . that does not mean the selection is based on that input”). Thus, we find that Kim’s NAND gate (the claimed “control circuit”) operates to determine its output (the claimed “value of the control signal”) based on its input of the sleep signal (the claimed “mode indicator”) and the memory cell value input (the claimed “leakage indicator”). As discussed in Section III.B, the Specification indicates that “select[ing] the value of the control signal based on the mode indicator and on the leakage indicator” recited in claim 13 is synonymous to determining the value based on the recited indicators. See Ex. 1101, 4:4–11. Thus, the evidence of record shows that Kim teaches “selecting, by the control circuit, a value of a control signal based on the mode indicator and on the leakage indicator,” as recited in claim 13.” slip op. at 44

“We are not persuaded by Petitioner’s argument and evidence. First, although Petitioner proposes “[s]ubstituting Lee’s inputs of leakage current and temperature for generating a power gate control signal” (i.e., Lee’s “control signal (BIAS)”) for “Kim’s inputs of leakage current and other ‘stimuli’ for generating a power gate control signal” (Pet. 64 (citing Ex. 1102 ¶ 115)), neither Petitioner nor Dr. Harris explains adequately how they are proposing to “substitute” Kim’s control signal with Lee’s “control signal (BIAS).” For example, Figure A reproduced above does not show how Petitioner or Dr. Harris proposes to use Lee’s “control signal (BIAS)” in the proposed combination. Petitioner asserts that “[a]lthough Lee’s control signal is analog and Kim’s control signal is digital, it was well known to apply teachings in an analog domain to a digital domain, and conversions between analog and digital domains were easy to implement.” Pet. 66 (emphases added) (citing Ex. 1102 ¶ 121; Ex. 1115). Dr. Harris similarly states that Figures A and B show examples of obvious ways to use in Kim’s system Lee’s teaching of setting conductance of the array based on temperature. A POSA would have found both of these ways obvious. That Lee uses an analog control signal and Kim uses a digital control signal would have presented no obstacle to a POSA. . . . That is, converting analog circuit elements and signals to digital was well known long before the ’026 patent. Ex. 1102 ¶ 121 (emphases added) (citing (Ex. 1115) (“Analog-to-digital converters (ADC’s) are ubiquitous, critical components of software radio and other signal processing systems.”)). But Dr. Harris does not explain adequately how “to use in Kim’s system” the digitized BIAS signal of Lee. See id. The only additional input signal shown in Figure A compared to Figure 4 of Kim is the temperature line that has the value of 0 when the temperature is cold and the value of 1 when the temperature is hot. See Ex. 1102 ¶ 116 (Fig. A). There is no explanation of how the modified teaching of the BIAS signal of Lee (i.e., modified or converted to a digital signal) would have worked in the proposed combination of Figure A.” slip op. at 69

“determine that Petitioner has demonstrated sufficiently that the combination of Kim and Lee teaches “a mode indicator generator for generating a mode indicator that indicates a desired mode of the power gated circuit,” as recited in claim 1, and has articulated sufficient reasoning with rational underpinning for combining Kim and Lee to arrive at the subject matter of this claim limitation. c.
