    • Skill levelSkill level patent owner adoptedDecided for patent owner

      “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. Thus, we adopt Patent Owner’s definition of one of ordinary skill in the art. We note, however, that neither party asserts that the outcome of this case rests on resolving the small differences between the parties’ definitions of the ordinarily skilled artisan.” slip op. at 8

      “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. Upon review of the parties’ arguments and supporting evidence, we agree that no terms require express construction. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

      “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. See Ex. 2001 ¶ 80.” slip op. at 50

    • 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

      “f) Conclusion – Initial Fintiv Analysis We have considered the circumstances and facts before us in view of the first five Fintiv factors. Because our analysis is fact driven, no single factor is determinative of our conclusion. Considering these five Fintiv factors, we determine that they favor a discretionary denial. 2.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

      “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). These arguments came too late, and we do not consider them. See Dell Inc. v. Acceleron, LLC, 884 F.3d 1364 (Fed. Cir. 2018) (“Unless it different colors “flash on and off” in response to user selection of the mode switch, thereby teaching the claimed “second switch that allows the first LED circuit to be disconnected from the AC voltage source and a second LED circuit to be connected to an AC voltage source.” Ex. 1004 ¶¶ 47, 62.” slip op. at 23

      “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.

      “The express language of claim 1 requires no solubility threshold, and dependent claim 10 of related U.S. Patent No. 10,288,620 B2 demonstrates that, where a solubility threshold was intended by the inventors of these patents, they knew how to expressly set forth that threshold in the claims. Compare Ex. 1004, 222:47–49 (“capable of imparting solubility in water”), with Ex. 1005, 218:12–14 (“The method according to claim 1, wherein each R is a non-ionic side group capable of imparting solubility in water in excess of 10 mg/mL.”). Thus, the claim language does not support applying a particular solubility threshold in claim 1. As noted by Patent Owner, the written description of the ’648 patent explains that “each R is independently a non-ionic side group capable of imparting solubility in water in excess of 10 mg/mL.” Ex. 1004, 2:21–22; Prelim. Resp. 17. This solubility threshold, however, is not in claim 1. Also, the ’648 patent states that this solubility applies only to some embodiments. See, e.g., Ex. 1004, 53:9–12, 55:6–20. We decline to import such a limitation from the written description into claim 1 absent reason for doing so. See SciMed Life Systems, Inc. v.

At this juncture in the proceeding, we have not made a final determination with respect to the patentability of the challenged claims, or with respect to claim construction. V. ORDER For the foregoing reasons, it is ORDERED that pursuant to 35 U.S.C. § 314(a), an inter partes review of claims 1–10, 18, and 20 of the ’417 patent is hereby instituted with respect to the ground of unpatentability set forth in the Petition; and FURTHER ORDERED that pursuant to 35 U.S.C. § 314(c) and 37 C.F.R. § 42.4, notice is hereby given of the institution of a trial; the trial will commence on the entry date of this Decision.” slip op. at 44

Patent Owner agrees that a POSITA may have a Ph.D. degree or master’s degree in chemistry, but asserts that a POSITA would also have “some experience with fluorescence” in addition to a Ph.D. degree in chemistry and that the experience of a POSITA with a master’s degree in chemistry is alternatively “industry experience in the field of biological detection systems.” Prelim. Resp. 5–6 (citing Ex. 2001 ¶ 7). For purposes of this Decision, we need not resolve these differences between the parties’ definitions, because any differences do not affect our analysis.13 If either party believes that adopting its preferred definition of the level of ordinary skill would have a material effect on the outcome of this proceeding, the party should address this issue during the instituted trial. slip op. at 11

In view of structure of claim 1 and the express definition provided in the ’303 patent, we agree with Patent Owner that claim 1 requires that the non-ionic side group R must be capable of imparting solubility to the claimed conjugated polymer (having constituents that satisfy the claimed variables noted above) in excess of 10 mg/mL.

      “be lifted for each patent for which the petition is denied. As noted above, there are six related petitions at the Board involving the patents before the court. The district court stayed the litigation “pending resolution of the IPR proceedings that have been instituted on the patents at issue in this case.” Ex. 2006, 2. Regarding the length of the stay, the district court explicitly ordered the parties not to use continuance of the fact discovery to October 28, 2022 “as grounds for . . . opposing institution of any post-grant proceeding.” Ex. 2007, 2. Regarding when the stay will be lifted, the order merely gives Patent Owner the opportunity to “seek to lift the stay as to any patents that are not instituted for review.” Ex. 2006, 2 (emphasis added). But we decline to speculate whether the district court would grant such a motion directed only to one of the six patents. Among the reasons warranting a stay of the litigation, the district court found “IPR has the potential to streamline issues for trial” and “the resources the parties will need to expend for experts could be significantly impacted by the outcome of any instituted IPR proceedings.” Id. Thus, the litigation is stayed pending the outcome of the six related proceedings, not merely the outcome of this institution decision, and the district court stayed the litigation for the explicit purpose of gaining efficiency and avoiding duplication of efforts by letting this inter partes review proceed to its conclusion first.14 See Prelim. Reply. 4–5. While Patent Owner may seek to lift the stay as to any patent for which institution is denied, the grant of any such request is uncertain. Accordingly, this factor strongly weighs against discretionary denial of institution.” slip op. at 15

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Decided for patent owner

      “The express language of claim 1 requires no solubility threshold, and dependent claim 10 demonstrates that where a solubility threshold was intended by the inventors of the ’620 patent they knew how to expressly set forth that threshold in the claims. Compare Ex. 1005, 213:26–27 (“capable of imparting solubility in water”), with id. at 218:12–14 (“The method according to claim 1, wherein each R is a non-ionic side group capable of imparting solubility in water in excess of 10 mg/mL.”). Thus, the claim language does not support applying a particular solubility threshold in claim 1. As noted by Patent Owner, the written description of the ’620 patent explains that “[i]n some embodiments, each R is independently a non-ionic side group capable of imparting solubility in water in excess of 10 mg/mL.” Id. at 54:2–10; Prelim. Resp. 12–13. This solubility threshold, however, is not in claim 1, and we decline to import such a limitation from the written description into claim 1 absent compelling reasons for doing so. See SciMed Life Systems, Inc. v. Advanced Cardiovascular Systems, Inc., 242 F.3d 1337, 1340 (Fed. Cir. 2001) (explaining that “reading a limitation from the written description into the claims” is “one of the cardinal sins of patent law”); see also Thorner v. Sony Comp. Entm’t Am., LLC, 669 F.3d 1362, 1366 (Fed. Cir. 2012) (“It is likewise not enough that the only embodiments, or all of the embodiments, contain a particular limitation. We do not read limitations from the specification into claims; we do not redefine words.”). In view of the foregoing, we construe the term “non-ionic side group capable of imparting solubility in water” to not include any particular numeric solubility threshold.13” slip op. at 12

Rather, teams of individuals with different expertise and various academic degrees would work together to design laser surgery systems intended to make incisions in the lens of the eye. Accordingly, we find that the person of ordinary skill in the art would have been an ophthalmic surgeon or someone with a Ph.D., M.S., or B.S. degree in physics, biomedical engineering, or a related science such as optical engineering, with experience in researching, manufacturing, or designing medical optics or medical lasers (e.g., Ph.D. or five or more years to compensate for lesser degrees).
