“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). We are persuaded that Petitioner’s proposal is consistent with the problems and solutions in the ’783 patent and prior art of record.

“2. “a switch configured to enable user selection” Prior to Institution, Patent Owner asserted that Petitioner applied an incomplete claim construction of the phrase “a switch configured to enable user selection.” Prelim. 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. Dec. 21. Patent Owner no longer disputes the construction of this term and applies our preliminary construction in its Response. PO Resp. 6.

“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

“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.

“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 parties present compelling argument and evidence that one of ordinary skill in the art would include those with experience in ophthalmology, as well as in the research, manufacture, and design of medical optics or medical lasers. Pet. 25; PO Resp. 9–10. The evidence of record also demonstrates that few individuals actually had such comprehensive experience. Rather, teams of individuals with different expertise and various academic degrees (Ph.D.s, B.S.s, and M.D.s) would work together to design laser surgery systems intended to make incisions in the lens of the eye. See, e.g., Ex. 1041 (several authors are M.D.s); Ex. 1042 (the authors’ degrees include Ph.D.s, an M.D., and a B.S.); see also Ex. 1053; Ex. 1054; Ex. 1055; Ex. 2010; Ex. 2019. Thus, we find that the person of ordinary skill in the art would have been either 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 nuclear engineering, having experience in researching, manufacturing, or designing medical optics or medical lasers (e.g., five years of experience for a Ph.D. or more to compensate for lesser degrees), and that such persons would have worked in collaboration with one another to fill any necessary gaps in knowledge (e.g., the engineer would consult the medical doctor on clinical issues or physiology and the medical doctor would consult the engineer on technical issues).

“summarized above, we find that the evidence of record does not support a conclusion that it would have been simple, straightforward, or otherwise routine to convert Swinger’s manual HeNe aiming system and Swinger’s surgeon-identification-of-target-tissue step to a computer-controlled, OCT-guided laser system. Even assuming that a person of ordinary skill in the art would have combined the teachings of Swinger and Baikoff to achieve a laser surgical system incorporating an OCT imaging system, that combination still would not have achieved the required “computer system” of the claims and all of its programmed surgical functionality, particularly, using a computer system to construct an anterior capsulotomy cutting region based on the image data. Petitioner relies on the ability of a person of ordinary skill in the art to configure Swinger’s computer control unit with the missing functionality, thus necessitating an electronic conversion of the steps performed using Swinger’s direct visualization method using a HeNe aiming beam to manually identify a surgical treatment region for laser surgery. Ex. 1039, 34:52–57; Ex. 2088 ¶¶ 55–59, 66. That conversion, however, involves the incorporation of OCT imaging technology as the basis for a computer-controlled system to plan and then implement the planned cataract surgery, two technological leaps that the record fails to show were known or suggested. In particular, the evidence of record does not support a conclusion that OCT was a well-known system used routinely, if at all, in the identification of treatment regions in the lens or lens capsule for cataract surgery, and further does not support a conclusion that a computer-controlled system to plan and to implement a planned cataract surgery in the lens was commonplace or even considered before the invention.” slip op. at 25

“The evidence of record demonstrates, however, that modifying an existing corneal surgery system to image and perform surgery on the lens was not the simple task asserted by Petitioner. For example, in a patent application filed in November 2009, Petitioner asserted that due to the different depth ranges for the laser’s focus, “laser systems designed for corneal procedures do not offer solution[s] for the considerable challenges of performing surgery on the lens of the eye.” Ex. 2007, 4:65–67, 5:30–36, code (22). Similarly, in a different patent filed in December 2008, Petitioner outlined the various challenges in developing laser surgery systems for creating incisions in the lens, including the difficulty in focusing a laser beam that propagates through regions of the eye with different optical properties and different curvatures. Ex. 2014, 15:51–16:18, code (22). This patent then states: Because of all the described hard challenges, corneal surgical laser systems are qualitatively simpler than lens surgical lasers. This is well supported by the fact that even though corneal surgical systems were suggested about 40 years ago, none have been adapted successfully for lens surgery to date. Id. at 16:13–18. During prosecution of another patent filed in 2008, and in responses to office actions filed in 2012 and 2013, Petitioner argued that a corneal OCT system “simply will not work” on the lens and that it would not have been obvious to modify such an OCT system to image the lens. Ex. 2015, 898, 1591, 1788. This was because OCT systems designed to image the lens would be required to deliver and scan an imaging beam “to a depth ten times bigger and a depth range ten times bigger” than an OCT system designed to image the cornea.

“Petitioner’s proposed definition of the person of ordinary skill in the art appears to be consistent with the level of skill in the art reflected in the prior art of record and the disclosure of the ’725 patent; however, we also agree with Patent Owner that such a definition should be flexible enough to include a person with a lesser academic degree and having experience working in the field, such as an engineer with clinical experience in ophthalmic surgery, as well as also including a medical doctor, such as an ophthalmic surgeon with experience working with medical optics and lasers, and that these people may collaborate. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Such an expanded definition of the person of ordinary skill in the art, including aspects of both parties’ definitions, is appropriate here, based on our review of the record. Thus, we find that the person of ordinary skill in the art would have been someone with a PhD, MS, or BS degree in physics, biomedical engineering, or a related science such as nuclear engineering, having more or less experience in research, manufacturing, or designing medical optics or medical lasers (e.g., 5 years for a PhD or more to compensate for lesser degrees), or an ophthalmic surgeon, but that such persons would have worked in collaboration with one another to fill any necessary gaps in knowledge (e.g., the engineer would consult the medical doctor on clinical issues or physiology and the medical doctor would consult the engineer on technical issues).

“Turning to the disputed term “automatically” in this context, we agree with Patent Owner that the plain meaning of the term “automatically” is that the “control system” can, on its own and without human intervention, perform the subsequently recited step. Resp. 11–15; see also Pet. 10 (Petitioner agreeing this is the plain meaning). This is supported by the Specification, which states, inter alia, that “the entire system is controlled by the controller CPU” and describes alternative embodiments where (1) the system is fully in control and where (2) user input identifies targets. Ex. 1027, 12:23–25, 13:25–44, Figs. 14, 15. However, we also agree with Petitioner that just because the claimed “control system” is configured/programmed to perform (i.e., capable of performing) some tasks “automatically” (i.e., entirely on its own), this does not mean user input (e.g., from a surgeon) must be altogether excluded. Pet. 10–11. In fact, user input must be possible and is within the scope of the independent claim. “By definition, an independent claim is broader than a claim that depends from it, so if a dependent claim reads on a particular embodiment of the claimed invention, the corresponding independent claim must cover that embodiment as well.” Littelfuse, Inc. v. Mersen USA EP Corp., 29 F.4th 1376, 1380 (Fed. Cir. 2022). Here claim 2, requiring automatic target identification, and claim 5, requiring user input on target identification, each depends from claim 1 and illuminates its scope, which must be broad enough to encompass both. Thus, although requiring (in claim 1) that a “control system” can perform certain recited functions, and that some are performed (according to claim 2) “automatically,” that same “control system” must also be capable of allowing a user input on the locations of targets for laser treatment (according to claim 5). Such optional user input required by dependent claim 5 is described in the Specification, which includes embodiments where a surgeon can adjust the size, location, and shape of the treatment pattern, can determine the optimal cutting contours in patients, and can provide “user input” to define targets or adjust computer-defined parameters as necessary. Ex. 1027, 10:55–45; 10:67–11:2, 13:25–55, 13:63–14:2. Regardless, the configuration of independent claim 1’s “control system,” which must be programmed to and capable of performing its own recited steps/functions, is not diminished by the requirements of either dependent claim.

“generally. “The presence or absence of a reasonable expectation of success is . . . a question of fact,” and this “requirement refers to the likelihood of success in combining references to meet the limitations of the claimed invention.” Intelligent Bio-Sys., 821 F.3d at 1366–67. Based on the record, we conclude that, even if it would have been potentially advantageous to in some way incorporate the use of Baikoff’s and Li’s OCT imaging and measuring into Swinger’s system and method for cataract surgery (for example, to replace the use of ultrasound imaging with OCT), we agree with Patent Owner that, other than the (ultimately) conclusory testimony of its witness Dr. Izatt (see, e.g., Ex. 1001 ¶¶ 110, 144, 151, 161, 163–165, 168), there is no persuasive evidence that the person of ordinary skill in the art would have combined these references with the result being a control system configured to (automatically or not in practice) image cataractous eye tissue, identify the targets therein (capsule and lens) to be cut with a laser, and then operate that laser to actually make those cuts based in some part on that imaging. See Resp. 15–34. We credit Dr. Kang’s testimony that, as of the invention, the person of ordinary skill in the art would not have relieved the surgeon of responsibility for identifying cutting regions for laser capsulotomy and cataract surgery (as taught by Swinger), and relegated such task to a computer, which subsequently performs the procedure. Ex. 2087 ¶¶ 36–38, 42, 46, 62–66; see also Ex. 2088 ¶¶ 56–59, 68–71 (Dr. Walter testifying similarly). Dr. Kang takes issue with Petitioner’s positions that Baikoff and Li teach or suggest such reliance on a computer because, according to Dr. Kang, neither Baikoff nor Li (and indisputably not Swinger) teaches using a computer to identify laser cutting regions or to control laser surgery, and, in fact, they suggest reliance on a surgeon to interpret their OCT images to plan a subsequent surgery. See, e.g., Ex. 2087 ¶¶ 36–38, 42, 46, 62–66. We further credit Dr. Kang’s testimony that Petitioner fails to adequately explain, even were the ordinarily skilled artisan intent on combining Baikoff’s and Li’s OCT imaging systems with Swinger’s cataract surgery system, how it would have been accomplished to overcome the “substantial challenges” and achieve the claimed invention. See id. ¶¶ 63– 66; see also Resp. 27–28 (addressing Petitioner’s lack of explanation as to how to implement the combination).19 We agree that, beyond merely suggesting plugging one system into another, Petitioner does not explain how the person of ordinary skill in the art would have programmed Swinger’s computer control system to use Baikoff’s and Li’s OCT imaging systems and tissue recognition and measurement algorithms to determine capsulotomy cutting regions and then implement the planned cutting with a laser, even from a rudimentary perspective.

“To act as its own lexicographer, a patentee must ‘clearly set forth a definition of the disputed claim term’ other than its plain and ordinary meaning.” Thorner, 669 F.3d at 1366 (citing CCS Fitness, 288 F.3d at 1366). “It is not enough for a patentee to simply disclose a single embodiment or use a word in the same manner in all embodiments, the patentee must ‘clearly express an intent’ to redefine the term.” Id.

That is precisely what the patentees did in the above-passage. Specifically, we find that they clearly set forth a definition that is different than the plain and ordinary meaning and, in so doing, clearly expressed an intent to redefine the term. That the patentees intended to redefine the term “storage module” is clearly expressed by the use of “as used herein”16 and “refers to” in the above-passage and is consistent with the patentees’ use of these same phrases when defining other terminology in the ’551 patent, as discussed above. slip op. at 18

“Generally . . . the preamble does not limit the claims.” Am. Med. Sys., Inc. v. Biolitec, Inc., 618 F.3d 1354, 1358 (Fed. Cir. 2010). A term in the preamble is a limitation only if it “recites essential structure or steps, or if it is ‘necessary to give life, meaning, and vitality’ to the claim.” TomTom, 790 F.3d at 1323. We agree with Petitioners that “wireless modem apparatus,” as recited in the preambles of claims 2 and 3, is not limiting. In particular, “wireless modem apparatus” does not provide antecedent basis for any term subsequently recited in claims 2–4; it does not provide any essential structure because the body of the claim recites a structurally complete invention; and it is not necessary to give life, meaning, and vitality to the claim. Further, Patent Owner’s argument that the preamble is limiting because it makes clear that the input signal is input to a wireless modem apparatus is unavailing because the body of claims 2 and 3 expressly recite, as the first element, “a receiver for frequency down-converting an input signal.” See Ex. 1001, 60:48–49 (claim 2), 61:2–3 (claim 3). And, Patent Owner’s arguments make clear that its attempt to read “wireless modem apparatus” as limiting is solely for the purpose of arguing that claims 2–4 require a transmitter, which is a structural element that is not recited in the claims. See, e.g., PO Resp. 72 (arguing that Tayloe does not disclose a transmitter), 79 (raising the same arguments directed to Lam). When the patentees intended to limit a claim to a transmitter, they expressly recited a transmitter in the body of the claim. See, e.g., Ex. 1001, 61:25–57 (Claim 6 recites “[a] wireless modem apparatus, comprising,” and expressly recites “a receiver” and “a transmitter” in the body of the claim.). Accordingly, for each of these reasons, we find that “wireless modem apparatus” recited in the preambles of claims 2 and 3 is not limiting. slip op. at 23

“The terms storage module and storage capacitance, as used herein, are distinguishable from the terms holding module and holding capacitance, respectively. Holding modules and holding capacitances, as used above, identify systems that store negligible amounts of energy from an under-sampled input EM signal with the intent of “holding” a voltage value. Storage modules and storage capacitances, on the other hand, refer to systems that store non-negligible amounts of energy from an input EM signal. Ex. 2029, 66:59–67 (emphases added); see Ex. 2016, 39–40 (discussing Patent Owner’s prior arguments to construe “storage module” in IPR2014- 00948). When defining certain terms in a section titled “General Terminology,” the ’551 patent repeatedly uses the phrase “when used herein” in combination with the phrase “refer(s) to.” See, e.g., Ex. 2029, 13:56–15:27 (mentioning a term followed by “when used herein,” followed by “refers to,” followed by a definition). For example, the ’551 patent states, “[t]he term digital signal, when used herein, refers to a signal that changes between discrete states, as contrasted to a signal that is continuous.” Id. at 15:7–9. As shown, the ’551 patent defines “digital signal” by stating “when used herein” followed by “refers to.” And, the same sentence also provides a comparison between “digital signal” and a signal that is continuous. Even though the passage describing “storage module” is not listed under the “General Terminology” section of the ’551 patent, the passage provides the same indications that the patentees clearly and unambiguously intended to define the term “storage module” by stating “as used herein” and “refer to”—hallmarks that the patentees were providing a lexicographic definition of the term. Vasudevan Software, Inc. v. MicroStrategy, Inc., 782 F.3d 671, 679 (Fed. Cir. 2015) (“An applicant’s use of the phrase ‘refers to’ generally indicates an intention to define a term.”) (citing In re Imes, 778 F.3d 1250, 1252–53 (Fed. Cir. 2015); Microsoft Corp. v.

Additionally, as with the term “digital signal,” the above-passage provides a comparison between “storage module” and “holding module” and uses the definitions of the terms to compare and contrast them. “To act as its own lexicographer, a patentee must ‘clearly set forth a definition of the disputed claim term’ other than its plain and ordinary meaning.” Thorner, 669 F.3d at 1366 (citing CCS Fitness, 288 F.3d at 1366). “It is not enough for a patentee to simply disclose a single embodiment or use a word in the same manner in all embodiments, the patentee must ‘clearly express an intent’ to redefine the term.” Id.
