    “F.3d at 1279–80, we begin our analysis with the Specification of the ’711 Patent. The Specification indicates when a UAV (such as the recited “reference aerial vehicle”) navigates autonomously, it flies without manual control, and can, for example, track and fly to a target using information captured onboard the vehicle itself. See Ex. 1001, 3:24–28 (“[I]t may not be desirable to manually control the interceptor aerial vehicle to follow the target UAV. In some embodiments, the interceptor aerial vehicle is able to autonomously track and fly to the target UAV using machine vision based on images captured by a camera of the interceptor aerial vehicle.”). The Specification also indicates that “autonomous” means more than just “automatic flight,” and clarifies that autonomous navigation occurs when a UAV that previously received a target location from an external source subsequently turns and flies itself towards the received location. See, e.g., id. at 4:15–17 (disclosing that the detected location of a target may be provided to an interceptor “to allow it to automatically and autonomously fly toward the direction of the detected location”); 15:64–16:3 (automatic and autonomous navigation occurs when an interceptor’s navigation component and/or flight controller receive the location of a target, and adjust the interceptor “to turn and fly towards the received location . . . based on the received location”); 16:49–60 (“For example, a flight direction and/or speed of an interceptor aerial vehicle are automatically and autonomously adjusted based on a location and size of the target within the captured image. . . . This allows the flight path of the interceptor aerial vehicle to be dynamically adjusted to track and follow a moving target.”).” slip op. at 11

    “have had reason to combine Beard and Laufer in the manner proposed by Petitioner, the combination would not satisfy the Autonomous Navigation limitation required by claim 12 because Laufer’s autopilot commands are generated by and transmitted from a remote command center (i.e., Laufer’s central controller 115). PO Resp. 15–16. In its Reply, Petitioner does not dispute that Laufer’s autopilot commands are generated by Laufer’s central controller 115, which is remote from the aircraft being controlled. See Reply 13–17. Petitioner asserts, however, that the combination still satisfies the Autonomous Navigation limitation because these autopilot commands are generated without human input. See id. Based on the complete trial record, Patent Owner’s arguments are persuasive. See PO Resp. 15–16; PO Sur-reply 42, 1–6; Ex. 2025 ¶¶ 84–87. The flight of Beard’s UAV 100 under the control of Laufer’s autopilot commands does not satisfy the Autonomous Navigation limitation of claim 12, as we have construed that limitation, because Laufer’s autopilot commands are generated at a location that is remote from UAV 100 (Laufer’s central controller 115.) See, e.g., Ex. 1010 ¶ 40 (“Central controller 115 uses autopilot command module 440 to generate autopilot aircraft commands”), ¶¶ 26, 30 (clarifying that central controller 115 and the controlled interceptor aircraft are separate devices that may communicate through a “wireless connection”), Fig. 4 (depicting “aircraft control commands 475” being generated externally from the depicted “Interceptor Aircraft”); see also Ex. 2025 ¶¶ 95–95. Petitioner never disputes that, in the proposed combination, Laufer’s central controller 115 would remain external to Beard’s UAV 100. See Reply 13–17. Instead, Petitioner relies on its proposed construction of the Autonomous Navigation limitation, which would have encompassed such an arrangement. See id. Our construction of the Autonomous Navigation limitation, which did not adopt Petitioner’s claim construction position, is dispositive of Petitioner’s argument. We thus determine that Petitioner has not shown by a preponderance of the evidence that claim 12 would have been obvious over Beard and Laufer.” slip op. at 15

Patent Owner has responded to the grounds of unpatentability involved in this proceeding by amending the claims in response to the Petition’s asserted prior art. See MTA 2, 25, Claims App. Petitioner does not argue otherwise. See generally MTA Opp. We determine that Patent Owner meets this requirement. 3. No Enlargement of the Scope of the Claims An amendment may not seek to enlarge the scope of the claims of the patent. 35 U.S.C. § 316(d)(3); 37 C.F.R. §§ 42.121(b)(1)–(b)(2). Patent Owner asserts that the amendments in the Motion do not enlarge the scope of the claims of the patent because each proposed substitute claim “retains all of the limitations of the corresponding challenged claim, and each proposed independent substitute claim adds further limitations.” See MTA 2, Claims App. Petitioner does not argue otherwise.

  • 112 supportDecided for patent owner

    “Having considered the evidence and argument cited by both parties, we determine there is sufficient written description support for the disputed portions of limitations [37.e1], [37.e3,] and [37.e4]. The ’452 application discloses selecting between groups of processing schemes (e.g., algorithms) depending on a confidence level, where the groups are, for example: high cost, high robustness algorithms; medium cost, medium robustness algorithms; and low cost, low robustness algorithms. See Ex. 2019 ¶¶ 146–147. These schemes or algorithms may be neural networks. See, e.g., id. ¶ 50 (including neural network as a type of algorithm); see also id. ¶¶ 109–110); see generally MTA Opp 1 (not disputing that schemes may be neural networks). Specifically, the ’452 application describes “algorithms that process video frames of one or more video data streams,” and “produce a prediction of objects within the video f[r]ame, as well as a confidence number that is a measure of quality for that prediction.” Id. ¶ 141. The ’452 application also discloses the concept of switching between neural networks based on confidence levels. In particular, the ’452 application discloses that a “process cycles through the processing schemes to produce a detection of an object,” for example, where “if the confidence number is higher than an activation number, an action is performed to stop or change a running group (i) and select or switch to group (ii).” Id. ¶ 146. More particularly, “a processing scheme from the group of (i) High cost (low refresh rate), high robustness algorithm[s] can select a cheaper processing scheme from the group of (ii) Medium cost, medium robustness algorithms.” Id. The ’452 application additionally discloses that schemes or algorithms (e.g., neural networks) are applied to individual video frames, and that the confidence levels that determine which neural network will be applied in the future are also derived from individual video frames. For example, as discussed above, the ’452 application describes that “[t]he processing schemes produce a prediction of objects within the video f[r]ame, as well as a confidence number that is a measure of quality for that prediction.” Ex. 2019 ¶ 141 (emphases added). The ’452 application also describes selecting and applying an individual neural network, rather than only selecting and applying a group of processing schemes. For example, as highlighted above, the ’452 application describes that “a processing scheme from the” “High” group “can select a cheaper processing scheme from the” “Medium” group. Id. ¶ 146 (emphases added). In our view, these disclosures, read together, would reasonably convey to one skilled in the art that the inventor had possession of the disputed subject matter described above.

    “We also agree with Patent Owner that the charge cut-off voltage is not necessarily the applied voltage during charging. PO Resp. 20. Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91. For example, as discussed in more detail below with respect to the Uemura grounds, when fast charging using constant current is used and the charging rate is not slow, the applied voltage will be higher than the battery voltage when the constant current charging phase is stopped. Ex. 2006 ¶ 91; Ex. 2013. Likewise, during constant current/constant voltage charging, the applied voltage approximates the battery voltage only when the battery is nearly completely charged. Ex. 2013; Ex. 2006 ¶ 91. Thus, the applied voltage may be, but is not necessarily, the charge cut-off voltage.

  • ExcludeMotion to exclude, deniedDenied

    “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. Petitioner never had a burden of establishing a method of running the Krames reference’s LED at this power output within a semiconductor light source.” slip op. at 9

    “We agree with Patent Owner that the challenged claims relate to light fixtures, LED packaging, and LED chip layer structure and that the ’770 patent claims reflect “a hybrid of the light bulb art and semiconductor art.” Resp. 16.

Petitioner’s expert, Dr. Lebby, agreed that a person having ordinary skill in 28:16. While Petitioner’s proposed description of a person having ordinary skill in the art could, in some instances, be sufficient to qualify a person as having ordinary skill, Patent Owner’s proposal is a more complete and accurate description of the level of skill commensurate with the scope of the challenged ’770 patent claims. Patent Owner’s description appears consistent with the prior art and patent specification before us and is supported by witness testimony. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (prior art itself may reflect an appropriate level of skill). For the purpose of this Decision, we adopt Patent Owner’s description.

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.

    “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.

    “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

Resp. 10 (citing Ex. 2001, 21-24). In reviewing the term, the District Court explained that the multi- scenario ECO database “stores parameters and allows for a quick estimation of an ECO’s impact across multiple scenarios.” Ex. 2001, 19. The District Court further summarized the ’655 patent as describing that a scenario image is “[f]irst” loaded, and if there is a design requirement violation, an ECO is determined for that scenario, and then subsequent scenarios are loaded to check whether the ECO from the first scenario will create new, or exacerbate existing, design violations. Id. (citing Ex. 1001, 4:21–33). However, as recognized by the Court, the process at the cited section is described in the ’655 patent as an “approach [that] may take an impracticably long time to fix design requirement violations in multiple scenarios” due to the long time that is required to load a scenario image. Id. at 24; Ex. 1001, 4:43–47. The Court reasoned that in order to determine an ECO to fix a violation, “determine” must involve “identifying” a possible fix and “checking” whether that fix is suitable. Id. at 23.

    “Petitioner assertion that Yoshimura’s estimation in step S5 is performed to check an identified ECO is supported by the record. In determining the change to be made (the ECO), Yoshimura uses estimated parameters for the third and fourth corner conditions, calculated in step S5 through the “Hold Margin” equation. Ex. 1007, 6:63–67. Those third and fourth corner conditions are then used to check potential layouts identified in step S6. Id. at 7:18–20 (“In step S6, the automatic EC device 16 searches for a layout that does not cause a timing error under any one of the first to fourth comer conditions from the analysis results of step S4 and step S5.”). In this manner, step S5 sets an initial third corner condition having estimated parameter values that is included, as the initial step, in checking an identified ECO at steps S6–S8. Thus, Yoshimura’s determination of a change to satisfy the corner conditions is, to use Dr. Edward’s phrase, “based on” its third and fourth corner conditions having parameters estimated in step S5.

This argument is not persuasive because claim 13 recites that the flow that enters each channel through the one aperture “bifurcates into two sub flows,” and requires that each of the recited outlet regions receives “one of the two sub flows” or “the other of the two sub flows.” This claim language is not satisfied by an outlet region that receives only a portion of one of the two recited sub flows. Claim 13 requires that each outlet region receive one of the same two sub flows that originally entered the microchannel. See also Ex. 2038 ¶ 108. Petitioner neither proposes a claim construction that would encompass such an embodiment, nor offers any persuasive evidence that a POSITA would read claim 13 to encompass such an embodiment. Accordingly, on this record, we are not persuaded by a preponderance of the evidence that Kang teaches or suggests a flow of heat exchange fluid that is bifurcated into two sub flows within each of the microchannels, wherein each of these two sub flows is received by one of the two outlet regions adjacent to the opposing ends of the microchannels, in the manner required by claim 13.” slip op. at 36
