    “proposed combination based on the argument that a POSITA would have been motivated to switch the layout responsive to a parameter value changing. Pet. 11–15 (citing Ex. 1003 ¶¶ 35–40, 47–52). For example, we agree with Petitioner that a motivation exists to change the layouts to “best suit the condition of [the] patient” because Naghavi expressly describes an “interactive and dynamic” GUI that “may automatically detect changes in health status . . . and automatically react and rearrange the available options to best suit the condition” of the patient. Ex. 1005 ¶ 63. The supporting expert testimony persuasively relies on this aspect of Naghavi when concluding that “such a change in the severity of a parameter can indicate a change in the patient’s health that may require close monitoring” and a POSITA “would have been motivated to implement this approach of the combination in order to achieve” Naghavi’s objectives.

    “appear to be that Patent Owner specifies that the POSITA’s knowledge and experience may include optical sensors and that the POSITA may have a degree emphasizing software. We do not deem these differences material, particularly because the optical sensors and technologies at issue are those used in physiological monitoring technologies. Moreover, both parties agree that the POSITA would have a working knowledge of physiological monitoring technologies. Ex. 1003 ¶ 22; Ex. 2079 ¶ 37. Nonetheless, we find the additional specificity of Patent Owner’s definition to be helpful. Also, Patent Owner’s definition appears to be consistent with the level of skill in the art reflected in the prior art of record and the disclosure of the ’911 patent. Accordingly, for purposes of this Decision, we adopt Patent Owner’s proposed definition of the POSITA. We note, however, that we would reach the same outcome under either definition of the POSITA.

    “Dr. Kenny’s explanation finds support in Raley, and we find his explanation credible. Ex. 1079 ¶¶ 9–11. We agree that Raley’s opening 26 has a vertical depth. In order for emitters 21, 22, 23, 24 to be flush with opening 26 as depicted in Raley’s Figure 3 (see PO Resp. 17–18 (arguing that LEDs are flush with opening 26)), the opening must have a depth to accommodate the thickness of the emitters. We further agree that opening 26 is within a solid body, namely interconnect cable 20. We also agree that, in view of the structure and function of Raley’s probe 40 and interconnect cable segment 20, a POSITA would have understood opening 26 is designed to receive the emitters therein. Given that Raley’s interconnect cable segment 20 includes opening 26 that is designed to receive emitters 21, 22, 23, 24 therein, Petitioner has persuaded us that Raley’s LEDs are recessed into a cavity under both the plain and ordinary meaning of “cavity” and Petitioner’s construction from the Delaware Litigation.” slip op. at 27

    “testimony regarding a POSITA’s understanding of Figure 11B of Abdul-Hafiz. Ex. 2079 ¶¶ 87–88. More pertinent to claim construction, however, is a POSITA’s understanding of the claim term in view of the Specification. See, e.g., Phillips, 415 F.3d at 1315 (“As we stated in Vitronics, the specification ‘is always highly relevant to the claim construction analysis. Usually, it is dispositive; it is the single best guide to the meaning of a disputed term.’” (quoting Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Circ. 1996))). In this regard, Petitioner points to Dr. Madisetti’s Rebuttal Expert Report, which was submitted on behalf of Patent Owner in the Delaware Litigation, where, upon reviewing the Specification of the ’911 patent for written description support for the claims, Dr. Madisetti testifies that “[a] POSITA would have known that the detection surface area of a given detector is essentially the entire surface area of the detector.” Ex. 1082 ¶ 912. During oral argument, Patent Owner attempts to reconcile the apparent inconsistency between this testimony and Patent Owner’s proposed construction. Tr. 34:20–36:12. In particular, Patent Owner asserts that, according to the ’911 patent Specification, the entire surface of the light-detecting side of the detector is the area that light reaches because there is “nothing blocking the entire area of the of the light-detecting side of the detector from receiving light.” Id. at 35:12–13. Patent Owner’s assertion, however, ignores EMI shield grid 2444 and foil 2450 that are placed on and at least partly cover the light-detecting side of the detector. Ex. 1001, 13:38–53, Fig. 24. Accordingly, we find Dr. Madisetti’s testimony regarding a POSITA’s understanding of the Petitioner’s construction, and we adopt Petitioner’s construction of “a detection surface area of the at least one detector” as the surface area of the light-detecting side of the detector.” slip op. at 16

    “reasons against it in the Sur-reply, we are persuaded that a POSITA would have found it obvious to modify Abdul-Hafiz’s aperture to have an area smaller than the detection surface area to prevent optical noise sources such as ambient light and piped light reaching the detector. We disagree with Patent Owner that Petitioner does not explain why a POSITA would have made Abdul-Hafiz’s aperture smaller than the detection surface area. Preventing optical noise sources explains why a POSITA would have made Abdul-Hafiz’s aperture smaller than the detection surface area because making the area of the aperture smaller than the detection surface area helps prevent optical noise sources from reaching the detector. Even if Abdul-Hafiz’s low noise housing 400 and fixed shield 1005 mitigate optical motivation to make something better. See Dystar Textilfarben GmbH & Co. Deutschland KG v. C.H. Patrick Co., 464 F.3d 1356, 1368 (Fed. Cir. 2006) (“[W]e have repeatedly held that an implicit motivation to combine exists . . . when the ‘improvement’ is technology-independent and the combination of references results in a product or process that is more desirable, for example because it is stronger, cheaper, cleaner, faster, lighter, smaller, more durable, or more efficient.”). Adding an additional protection against optical noise by limiting the diameter of Abdul-Hafiz’s aperture would have enhanced the optical noise mitigation of the low noise housing and fixed shield. Moreover, apart from Abdul-Hafiz, Petitioner does not identify in the prior art an opening having a smaller area than a detection surface area. Petitioner, however, identifies a known relationship between the size of the opening relative to the detection surface area and preventing optical noise from ambient light and piped light. Pet. 50 (citing Ex. 1004 ¶¶ 3, 33); Reply 11–12 (citing Ex. 1011, 96–97, Fig. 6.6; Ex. 1079 ¶¶ 30–32; Ex. 1080 ¶ 73; Ex. 1081, 12:51–63, 14:19–47, 14:28–47). When one parameter is known to influence a specific result, such as the size of the opening relative to the detection surface area preventing optical noise, discovering the optimum value of the parameter is generally obvious. See In re Boesch, 617 F.2d 272, 276 (Fed.

Motivation to Combine After summarizing its proposed combination, Petitioner provides a number of reasons for combining the references. Pet. 9–17. Petitioner breaks its motivation to combine arguments into three separate categories that we address below. See id. at 13–17. Patent Owner raises a number of arguments in support of its contention that “a POSITA would not have been motivated to combine the references to replace a measured value of one parameter with the measured value of another parameter,” which we address in the context of Petitioner’s arguments below. See PO Resp. 44–57. Many of Patent Owner’s arguments rely on Patent Owner’s proposed claim constructions for “replaced” and “measured value,” which we do not adopt for the reasons discussed above. For example, the first sentence in Patent Owner’s argument contends that “Naghavi, Hochstedler and Burnes do not disclose using the same screen area to display two currently measured parameters,” but we do not read the claims as requiring the display of “two currently measured parameters” consistent with Patent Owner’s construction for “measured values.” See id. at 44 (citing Ex. 2042 ¶ 125).

    “We disagree with Petitioner’s argument because it fails to address Dr. Schubert’s academic and other experience with GaN transistors. Dr. Schubert is currently a tenured full professor in the Department of Electrical Computer, and Systems Engineering at Rensselaer Polytechnic Institute and was previously a tenured full professor in the Department of Electrical and Computer Engineering at Boston University. Ex. 2001, 129. Additionally, Dr. Schubert was the director of Boston University’s Semiconductor Devices Research Laboratory. Ex. 2001, 129. Dr. Schubert persuasively explains that his general expertise is in the field of electrical engineering and applied physics, including semiconductors, processing, and devices and his specific expertise is in the field of semiconductor materials (such as GaN), semiconductor devices, semiconductor integrated circuits, ohmic contacts, Schottky contacts, HEMTs, and optoelectronic devices such as light-emitting diodes (LEDs). Ex. 2001 ¶ 11, App’x A pp.129–137. His experience includes “the design, growth, fabrication, and testing of semiconductor devices as well as the employment of these devices in a variety of applications” and he is “familiar with both the design of such transistors [HEMTs] and the manufacturing processes used for FETs. Ex. 2001 ¶ 11, App’x A, pp. 129–137. He is an author or co-author of numerous text books and articles, and co-inventor of numerous patents, including those dealing with HEMT transistors and GaN devices. Ex. 2001 ¶ 13, App’x A, pp. 129–137. Petitioner fails to present any persuasive argument or evidence that Dr. Schubert’s extensive education and experience regarding GaN transistors is insufficient or lacking such that his testimony should be given little weight. Finally, we disagree with Petitioner’s additional argument that that its expert’s testimony (Dr. Shealy) should be given more weight than Patent Owner’s expert’s testimony (Dr. Schubert) because “[u]nlike Dr. Schubert, Dr. Shealy is one of the pioneer scientists in the field of GaN transistors.” Reply 34 (stating that Dr. Shealy’s research lab built the first GaN HEMT device on silicon in 1999 and citing Ex. 2002, 87:19–238). Obviousness is determined through the lens of a “person of ordinary skill in the art,” not through the lens of a person with extraordinary skill or a pioneer in the field. Given Dr. Schubert’s extensive relevant education and experience, Petitioner does not persuasively explain why Dr. Shealy’s testimony on any specific topic, or his testimony in general, should be given more weight than Dr. Schubert’s.” slip op. at 16

    “In order to determine whether an invention would have been obvious at the time the application was filed, we consider the level of ordinary skill in the pertinent art. Graham, 383 U.S. at 17. In assessing the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC, Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (quotation omitted). Petitioner contends a person of ordinary skill in the art “would have possessed at least a four-year degree in electrical engineering, chemical engineering, physics, or material science, or a closely related field, and at least two years of experience in semiconductor device design or fabrication, including the processing of semiconductor materials, analysis of device operation, or the development of new device topologies.” Pet. 5–6. Petitioner contends “[a]dditional education could substitute for professional experience and vice versa.” Id. at 6. Patent Owner contends that a person of ordinary skill in the art would have had “at least a four-year degree in electrical engineering, physics, material science, or a closely related field, and three years of professional work experience in the epitaxial growth, design, and fabrication of semiconductor electronic devices, including those of GaN.” PO Resp. 7 (citing Ex. 2009 ¶ 82).

    “compensated GaN layer above the barrier layer, and a gate contact above the compensated GaN layer.” Ex. 1001, 5:12–18. Petitioner contends the term “compensated” indicates that the step of compensating the GaN layer has already occurred, such that the term “compensated GaN layer” should be construed as a “‘[d]oped GaN layer formed with a step to passivate its impurities’ which is a ‘product-by-process’ limitation.”5 Pet. 12–14. And, because compensation with hydrogen was the “critical step” distinguishing the claims from the prior art, and because hydrogenation in as-grown III-nitride materials had been well known for over a decade by 2009, Petitioner contends “compensated” “cannot be interpreted as mere hydrogen presence in as-grown material, a well-known property of doped GaN.” Id. at 15. Patent Owner contends “compensated GaN material” should be construed as “a semiconductor GaN gate material in which one type of impurity (for example, donor) cancels the electrical effects of the other type of impurity (for example, acceptor).” PO Resp. 11 (citing Ex. 2009 ¶ 92) (emphasis added). Patent Owner contends this construction is consistent with the IEEE dictionary, which defines “compensated semiconductor” as 5 Given that product-by-process steps in a device claim are not entitled to patentable weight, Petitioner contends “the prior art only need show a material with passivated impurities to show unpatentability, not the step to achieve it.” Pet. 15–16. “[a] semiconductor in which one type of impurity or imperfection (for example, donor) partially cancels the electric effects of the other type of impurity or imperfection (for example, acceptor).” PO Resp. 14 (quoting Ex. 2004). Patent Owner contends its construction is also consistent with the written description of the ’294 patent, which explains that a compensated GaN material is part of the gate and includes a p-type impurity that imparts an electrical effect (i.e., conductivity), as well as a second impurity, e.g., hydrogen, that partially cancels the electrical effect of the p-type impurity, rendering the layer semi-insulating. Id. at 14–15 (citing Ex. 1001, 3:10–13, 3:43–45). On this record, we construe “compensated GaN layer” as “a GaN layer in which one type of impurity (for example, donor) partially cancels the electric effects of the other type of impurity (for example, acceptor).” This is consistent with the disclosures of the ’294 patent, the IEEE dictionary definition, and the construction ultimately adopted by the ITC. Ex. 2004, 3; Ex. 1049, 16–17 (ITC construing “compensated GaN layer” to mean “a GaN layer in which one type of impurity partially cancels the electrical effects of another type of impurity”); Ex. 1001, 3:43–45 (explaining that the compensated GaN layer of the ’294 patent is formed through the “passivation of a p-type impurity using hydrogen”). For the reasons set forth below, however, we decline to construe “compensated GaN layer” as a product-by-process claim term (as asserted by Petitioner), or to limit the compensated GaN layer to a gate material (as asserted by Patent Owner).” slip op. at 11

  • Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageDisclaimer not foundDecided for petitioner

    “There are two exceptions to the general rule that we apply the ordinary and customary meaning of a claim term: (1) when a patentee sets out a definition and acts as his own lexicographer, or (2) when the patentee disavows the full scope of a claim term either in the specification or during prosecution. See Thorner, 669 F.3d at 1365. The standards for lexicography and disclaimer, however, are “exacting.” Id. at 1366. There is no argument that the patentees acted as their own lexicographer to redefine the term “compensated GaN layer.” With respect to disavowal, a “patentee may demonstrate intent to deviate from the ordinary and accustomed meaning of a claim term by including in the specification expressions of manifest exclusion or restriction, representing a clear disavowal of claim scope.” Thorner, 669 F.3d at 1366 (quoting Teleflex, Inc. v. Ficosa N. Am. Corp., 299 F.3d 1313, 1325 (Fed. Cir. 2002)). As noted by Patent Owner, the title of the ’294 patent is, in part, “Compensated Gate MISFET” and much of the discussion of the ’294 patent is of a compensated GaN layer that is directly below the gate contact and above a barrier layer and operates in conjunction with the gate contact to control the on/off state of the transistor. PO Resp. 12–14. We are presented with insufficient argument or evidence to conclude, however, that these disclosures rise to the level of a disclaimer. For example, although the title of the ’294 patent is directed to a “Compensated Gate MISFET,” claim 1 is more broadly directed to “[a] column III Nitride transistor.” Ex. 1001, 5:12, code (54). Nor are we directed to an expression or statement of manifest exclusion in the ’294 patent that would serve to disclaim any “compensated GaN layer” that is not directly below the gate and/or that does not function in concert with the gate electrode to control the on/off state of the transistor. See Thorner, 669 F.3d at 1366. With respect to the stated goals of the invention, as noted by Patent Owner, one of the primary purposes of the compensated GaN layer of the ’294 patent is to reduce gate leakage and gate capacitance. Ex. 1001, 2:13– 19, 3:18–21 (“[U]sing a compensated semiconductor layer 38 leads to low gate leakage during device operation.”). We cannot use the goals of the invention, however, to rewrite the claims or insert terms that are not present. See Thorner, 669 F.3d at 1366. Moreover, the prior art of record indicates that a compensated GaN layer that is below the gate contact and above a barrier layer, but not part of the active gate structure, may also “decrease the leakage current between the gate and the drain.” Ex. 1006 ¶¶ 44 (“Even when a positive bias of 5 V or higher is applied to the gate electrode, no significant gate-leakage current is observed.”), 61. As such, evidence of record suggests that a person of ordinary skill in the art would have understood that one of the primary goals disclosed in the ’294 patent is achieved regardless of whether the compensated GaN layer is part of the gate, or simply in close vicinity to the gate. In view of the foregoing, we are not persuaded that the written description of the ’294 patent indicates that the “compensated GaN layer” must be part of the gate structure.” slip op. at 17

  • Obviousness (§103) › Objective indicia / secondary considerations › NexusObjective indicia no nexusDecided for petitioner

    “To be probative, Patent Owner must prove there is a nexus between the presented evidence and the merits of the claimed invention. See Demaco Corp. v. F. Von Langsdorff Licensing Ltd., 851 F.2d 1387, 1392 (Fed. Cir. 1988). A rebuttable presumption of nexus applies when the “patentee shows that the asserted evidence is tied to a specific product and that the product ‘is the invention disclosed and claimed.’” Fox Factory, Inc. v. SRAM, LLC, 944 F.3d 1366, 1373 (Fed. Cir. 2019) (quoting Demaco, 851 F.2d at 1392). “That is, presuming nexus is appropriate ‘when the patentee shows that the asserted objective evidence is tied to a specific product and that product embodies the claimed features, and is coextensive with them.’” Id. (quoting Polaris Indus., Inc. v. Arctic Cat, Inc., 882 F.3d 1056, 1072 (Fed. Cir. 2018)). If the praise is not limited to the features of the claimed invention, the patent owner may still prove nexus “by showing that the evidence of secondary considerations is the ‘direct result of the unique characteristics of the claimed invention.’” Id. at 1373–74 (quoting In re Huang, 100 F.3d 135, 140 (Fed. Cir. 1996)). Patent Owner contends that the compensated gate of the ’294 patent “was a breakthrough invention and resulted in the first commercially viable enhancement-mode GaN transistor.” PO Resp. 60 (citing Ex. 2009 ¶¶ 192– 193, 197; Ex. 2021). Patent Owner further contends that this achievement required the counter-intuitive use of a compensated gate material in the gate structure, and represented “a technological leap that laid the foundation for viable enhancement-mode GaN transistors.” Id. at 61–62. For this achievement, Patent Owner contends the inventor, Dr. Alex Lidow, received the 2015 SEMI Award. Id. at 60 (citing Ex. 2021). Upon review of Patent Owner’s evidence and the parties’ arguments, we find that Patent Owner’s objective indicia evidence is entitled to little, if any, weight. The evidence of praise relied upon by Patent Owner is not clearly linked to the claimed invention or any particular product having each of the claimed features of the ’294 patent. Ex. 2021. For example, the 2015 SEMI award was provided to Dr. Lidow “for commercialization of GaN power devices.” Id. An article explaining the award indicates that “high cost” previously “limited [the] commercial success” of GaN technologies, but Dr. Lidow was able to overcome these issues, “from resolving packaging limitations to establishing a low-cost supply chain,” “through persistence.” Id. This praise is not demonstrably linked to the claimed invention or any particular device, and does not mention the use of a compensated gate, or any other relevant feature recited in the claims. In view of the foregoing, we determine that Patent Owner’s objective evidence of non-obviousness is entitled to little, if any, weight.” slip op. at 20

    “We agree with Petitioner that Oka is not cumulative of Jones. Jones discloses an impedance measuring system for measuring the impedance of each well of a multiwell plate. Ex. 1006, code (57). Moreover, Jones clearly teaches that the daughter boards in its system “may be equipped with multiple analog-to-digital converters.” Id. ¶ 18. Oka, in contrast, does not. As Patent Owner acknowledges, “Oka is a planar multielectrode array that 11 Oka et al., “A new planar multielectrode array for extracellular recording: application to hippocampal acute slice,” 93 J. of Neuroscience Methods 61– 67 (1999) (Ex. 1026) (“Oka”). measures via extracellular recording instead of impedance.” Prelim. Resp. 51 n. 10 (emphases added). This is consistent with the applicants’ arguments during prosecution that Oka does not disclose a multiwell plate, plurality of wells, or even measuring cell-substrate impedance. See, e.g., Ex. 1002, 191–193. Moreover, as Petitioner points out, Oka appears to disclose only a single ADC connected to a switch. See Ex. 1026, 63 (Fig. 2); see also Ex. 1002, 188 (applicant urging that “Oka uses a switch to connect the AD-C to different electrodes at different times” and therefore is not performing measurements for individual electrode arrays).
