    “specific requirements of the claims.” McRO, Inc. v. Bandai Namco Games America Inc., 837 F.3d 1299, 1313 (Fed. Cir. 2016) (quoting In re TLI Commc’ns LLC Patent Litig., 823 F.3d 607, 611 (Fed. Cir. 2016)). But “failing to account for the specific requirements of the claims” is what Petitioner’s analysis of the claim limitations appears to do. Petitioner’s argument that “the focus of the claims” is captured by a single claim element (f3) not only ignores that that limitation recites performing two specific software tasks simultaneously—which we are not persuaded is an abstract idea—but also asks us to disregard multiple technical aspects recited in the claims, such as identifying a link, determining whether an installation client is available on the device, invoking the installation client, and redirecting to the device an app store. See, e.g., Ex. 1001, 21:12–41; Revised MTA 24–25. That is, under Step 2A of the Guidance, we are neither persuaded that limitation f3, which Petitioner points us to, recites an abstract idea (Prong 1), nor that the other limitations recited in the independent claims fail to integrate the alleged abstract idea into a practical application (Prong 2). Petitioner characterizes the claims as directed to multitasking, which Petitioner describes as an example applied to improve a user experience, i.e., as related to organizing human activity. Pet. 29. Although the Guidance recognizes certain methods of organizing human activity, including certain activity between a person and a computer, as constituting a patent-ineligible abstract idea, we are not persuaded that the claims here fall within the scope of such activity. See Guidance, 84 Fed. Reg. at 52 (listing fundamental economic principles or practices, commercial or legal interactions, and managing personal behavior or relationships as organizing human activity). The claimed invention may result in multitasking on the device, but the background instead of directing the user to an app store, thereby maintaining user experience with the foreground application, and do not recite an abstract idea. And although that process does result in improving user experience, the claims recite more than that mere result; they recite specific steps—invoking, without exiting the foreground software application, the installation client for downloading and installing applications on the device to run in the background—that accomplish the desired result. See Finjan, Inc. v. Blue Coat Sys., Inc., 879 F.3d 1299, 1305–06 (Fed. Cir. 2018) (finding a method that employs a new kind of file in a computer security system directed to a non-abstract improvement in computer functionality, rather than the abstract idea of computer security writ large).

    “When the application package 172 has been received by the client system 130, the App Manager 180 may extract or retrieve a set of requested permissions 174 from the application package 172, and present a request to the user for asking for approval to perform operations corresponding to the requested permissions, e.g., opening files, accessing contact information, accessing a camera on the client device 130, and so on. . . . In particular embodiments, when the requested permissions 174 have been requested, and a response specifying a set of accepted permissions 176 has been received from the user, the set of accepted permissions 176 may be compared to the set of requested permissions 174. If the sets are the same, then the installation process may continue, and the App Manager 180 may invoke an installer 182 to install the application package 172. Ex. 1003, 8:67–9:22 (emphasis added). That is, the set of permissions to be checked are obtained by the App Manager once the download of the application package to be installed is initiated. See id. at 8:59–61 (“when the download is initiated by a request sent from the client system 130 to the server 162, the server 162 may send the requested object, e.g., the download page 168 or the application package 172, back to the client system 130”). And these permissions relate to operations that the installed applications may perform, e.g., opening files, accessing contact information, accessing a camera on the client device. Id. at 9:6–7. These permissions may also indirectly determine whether the installation client can install that app. See id. at 9:33–38. There is no suggestion in Pasha, however, that these permissions have anything to do with the host application, i.e., the second software application. said second software application is eligible to use capabilities of the installation client.” RMTA 25; see also Ex. 1001, 15:11–14 (“The installation client, upon receiving an instant install link, checks the eligibility of the caller and if identified as eligible continues the process of downloading the app.”). Pasha does not teach or suggest checking eligibility of its host application in any way or at any point. Moreover, as Patent Owner points out, Pasha’s App Manager performs the eligibility check after it downloads the app package, further supporting that Pasha’s eligibility check has nothing to do with the host application.9 Dr. Almeroth testifies that “Pasha discloses the App Manager 180 confirming that it has obtained the required permissions, which, in [his] opinion, a [person of ordinary skill in the art] would understand may include inter alia that the ‘second software application’ (e.g., the host application invoking the app manager) is eligible to use its capabilities.” Ex. 1035 ¶ 68.

Petitioner’s argument based on this new evidence is therefore forfeited.

    “Kuo discloses a “high efficiency light” that uses LEDs to emit light, as well as different lenses to amplify the intensity of the light emitted from the LEDs. See Ex. 1013, 1:6–9. Although Kuo focuses primarily on using its light as a traffic signal, Kuo is not limited to this embodiment and broadly claims “[a] high efficiency light.” Id. at 3:14–4:23 (Compare claim 1 directed to “[a] high efficiency light,” with claim 2 directed to use of the light of claim 1 “as a signal light”). Thus, we find that Kuo is in the same field of endeavor as the ’551 patent, i.e., LED lighting systems. that Kuo meets the “reasonably pertinent” prong of the analogous art test. KSR instructs that “familiar items may have obvious uses beyond their primary purposes, and a person of ordinary skill in the art often will be able to fit the teachings of multiple patents together like pieces of a puzzle.” KSR, 550 U.S. 398, 402 (2007). Given this instruction, the Federal Circuit has explained that when considering whether prior art is reasonably pertinent we must look beyond the primary problem the inventor was seeking to solve. See Wyers v. Master Lock Co., 616 F.3d 1231, 1238 (Fed. Cir. 2010) (explaining that in analyzing whether the prior art is reasonably pertinent we must construe the scope of analogous art “broadly”); see also Donner Tech., LLC. V. Pro Stage Gear, LLC, 979 F.3d 1353, 1360 (Fed. Cir. 2020) (explaining that the “reasonably pertinent” analysis must look to all of the problems to which the claimed invention relates, and must not be analyzed so narrowly as to effectively collapse the “field-of-endeavor and reasonablepertinence inquiries”). Here, although the ’551 patent is primarily focused on ways to efficiently drive LEDs using AC power, the ’551 patent is also concerned with methods of assembling an LED lighting system, including the use of: an insulating substrate, a heat sink, a reflective material on which to mount the LEDs, a lens for directing light, and a light changing or enhancing substance(s). Ex. 1001, 5:6–31, code (54) (noting that the ’551 patent is directed to both AC LED drive methods and an apparatus). Kuo expressly discloses the design of a housing that uses a lens and a light reflecting surface to maximize the light obtained from LEDs. These disclosures are reasonably pertinent to at least one problem the ’551 patent was intended to solve, e.g., what techniques and materials should be used to construct an analogous art to the ’551 patent under both prongs of the analogous art test.” slip op. at 15

    “understanding of a person of ordinary skill in the art at the time of the invention. Graham, 383 U.S. at 13, 17. Petitioner asserts that [a] person of ordinary skill in the art (“POSITA”) . . . would have had a bachelor’s degree in electrical engineering, or similar technical field, with two years of relevant experience in the field of design and/or development of LEDs and circuits in the context of lighting control systems. An increase in experience could compensate for less education. Pet. 9 (citing Ex. 1002 ¶ 35). Patent Owner does not dispute the level of skill in the art. See PO Resp. 32 (referring to, but not disputing, Petitioner’s proposed level of skill).

Resp. 19–22. Patent Owner contended that the switch must be “physical” and that a user must “be able to directly select an outcome.” Id. at 19. Our Institution Decision preliminarily construed “a switch configured to enable user selection of the different color temperatures of light” to permit a user to select the color temperature through direct or indirect use of the switch.

    “We view Petitioner’s combination to be sufficiently clear, setting forth sufficiently “articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” KSR, 550 U.S. at 418. Petitioner explains that “Grajcar discloses a switch (switch 2115) configured to enable user selection” and that “[t]o the extent [Patent Owner] argues that switch 2115 does not explicitly show ‘a switch configured to enable user selection,’ it would have been obvious to modify Grajcar by adding a switch that allows user input, as taught by Walter.” Pet. 26–27 (citing Ex. 1004, ¶¶ 107, 102–112, 192–195, Fig. 21; Ex. 1002 ¶¶ 72–73). This combination would have involved “integrat[ing] the LED circuits and switch of [Grajcar] Figure 21 with the LED bulb disclosed in Walter.” Id. at 21 (emphasis added). That is, the proposed combination simply aims to use Grajcar’s LED circuit in Walter’s bulb, so that Walter’s switch may actuate Grajcar’s LED circuit. See id. at 21–23, 27. Petitioner confirmed this position at the oral hearing, explaining, “so the proposed combination, looking again at Slide 13, it’s taking all of the circuits in [Grajcar] Figure 21 and putting them into the bulb of [Walter] Figure 2 where any user selection of color temperature is done using [Walter’s] Switch 170.” Tr. 11:20–23. Not only is Petitioner’s proposed combination sufficiently clear, but by arguing that Petitioner provides no “explanation of how the resulting combination would operate” or “what specific elements of Walter would be incorporated into Grajcar,” Patent Owner essentially attacks the Petition for not explaining how to bodily incorporate Grajcar into Walter. But “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . . Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” MCM Portfolio LLC v. Hewlett-Packard Co., 812 F.3d 1284, 1294 (Fed. Cir. 2015) (quoting In re Keller, 642 F.2d 413, 425 (CCPA 1981)). Patent Owner’s bodily incorporation argument fails to undermine Petitioner’s persuasive showing. In any event, Petitioner contends, and Patent Owner does not dispute, that “[i]t would have been well within the skill of a POSITA to implement Grajcar’s LED light with the user interface of Walter,” as “[t]he circuits described in Grajcar and claimed in claim 1 are extremely basic.” Pet. 23; see also Ex. 1002 ¶ 66 (Dr. Lebby testifying the same).” slip op. at 15

    “Given the breadth of the claims and specification, as well as Patent Owner’s implicit prosecution acknowledgement, we find the intrinsic evidence dispositive in this case of the meaning of “disconnected” as encompassing an electrical disconnection sufficient to turn the LED circuit off, including an electronic switch like a transistor to perform the electrical disconnection.” slip op. at 13

  • Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble limitingDecided for petitioner

    “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. Cir. 2019) (citations omitted). The body of claim 9 refers back to the preamble by reciting, “wherein the LED lighting system is driven with the AC voltage source.” Ex. 1001, 20:25–26. As such, the body of the claim relies on the preamble for antecedent basis support, and we determine that the preamble of claim 9 is limiting.” slip op. at 47

    “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).

    “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.
