  RulingsFinal written decision

  • BurdenNot shown unpatentable

    “A petition must identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim.” 35 U.S.C. § 312(a)(3) Here, Petitioner merely provides general assertions about multiple references, without clearly identifying how, or why a POSITA would have been motivated, to modify the processes disclosed in those references to arrive at the claimed invention. Thus, the Petition does not state with particularity that Saxler’s particular technique for etching is to be used instead of Beach’s etching step when substituting Beach’s self-aligned process for Saxler’s two mask process. Nor does the Petitioner provide a sufficient reason, absent hindsight, why a POSITA would have been motivated to combine the references to result in a process that forms Saxler’s Modified Figure 1A. Thus, for these additional reasons, Petitioner has not shown by a preponderance of the evidence that claim 1 would have been obvious over Saxler, Beach, and Shenoy.” slip op. at 34

    “remove the recess in Saxler Figure 1A to arrive at the allegedly enhancement mode transistor of Modified Figure 1A. Contrary to Petitioner’s assertions in its Reply and at the hearing, the Petition makes no argument that a POSITA would have removed the recess from Saxler Figure 1A to realize the benefits of an enhancement mode transistor. See Reply 4–5; Pet. 24–68. Rather, the Petition merely asserts that a POSITA would have understood that the gate recess of Figure 1A is optional without providing any persuasive reason why a POSITA would have removed the gate recess but retained the sloped sidewalls of Figure 1A. Pet. 25, 40, 45. For example, Petitioner asserts that Saxler’s gate contact may be “recessed or non-recessed” and that when the gate recess shown in Figure 1A is not utilized, Saxler would have the structure of Saxler Modified Figure 1A. Pet. 25 (citing Ex. 1003 ¶ 81; Ex. 1007 ¶ 52, 66); see also Pet. 40, 45 (citing Ex. 1007 ¶ 52). Neither of these paragraphs provide sufficient motivation to a POSITA to remove the gate recess from Saxler Figure 1A. Saxler paragraph 52 states: Exemplary devices according to some embodiments of the present invention are schematically illustrated in FIGS. 1A through 6. Thus, while embodiments of the present invention are described herein with reference to a recessed gate structure or a non-recessed gate structure, other embodiments of the present invention may include or not include a gate recess. Accordingly, embodiments of the present invention should not be construed as limited to the particular exemplary embodiments described herein but may include any suitable structure having a cap layer and/or passivation layer as described herein. Ex. 1007 ¶ 52. Petitioner’s expert, Dr. Shealy states that he understands paragraph 52 to mean that it is “fair game to pull the recess out of any of those figures [Figures 1A through 6].” Ex. 2004, 39:12–21.

    “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

    “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

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

    “the cable hangers (which support the current wires, data wires and other wires). That is, a single multi-function line supports the cable hangers, as a messenger wire, and provides a current path, as a grounding conductor.” Ex. 1001, 2:33–37 (emphasis added). And the sentence following that passage, which is cited by both parties, states: “Accordingly, as used herein, a ‘multi-function line’ means a tension member that supports current wires and/or cable hangers, and, which is conductive.” Ex. 1001, 2:37–40 (emphasis added). The sentences immediately following that sentence provide additional context, stating: “That is, a messenger wire is not a ‘multi-function line.’ Similarly, a conductor that does not support other constructs is not a ‘multi-function line.’” Ex. 1001, 2:40–42 (emphasis added). Thus, the specification indicates that a multi-function line is a tension member, “is conductive,” and supports other constructs such as current wires and/or cable hangers.

    “First, we agree with Petitioner that Patent Owner has not shown that the cited products are coextensive with, and have the required nexus between, the products and claim 1. See Reply 18–29. Even if Patent Owner sells an “Integrated Grounding System” that satisfies each limitation of claim 1, that system is undeniably comprised of “various” “exemplary” interchangeable parts that have uses outside of the claimed invention, that at least purportedly relate to many other of Patent Owner’s patents, and that were known in the prior art. E.g., Ex. 2064, ¶ 304 (identifying “exemplary” product part numbers, including CAB-9605, CAB-9705, CAB-9760, and CAB-9607), n.10; App’x A, A5 (identifying a part number “representative” part the “mid-pier kit”); Ex. 1049, 6–7 (identifying Patent Owner’s patent’s relating to different part numbers). For example, Patent Owner identifies two patent numbers purportedly protecting its “grounding Mid Pier Kit,” the ’551 patent and US Pat. No. 10,461,518. Ex. 1049, 6–7. Patent Owner identifies three of its patents as protecting its copper messenger wire, part number CAB-9605: (i) the ’551 patent, (ii) US Pat. No. 10,461,518, and (iii) US Pat. No. 10,811,859. Id. And Patent Owner identifies eight different patents, but not the ’551 patent, as protecting the cited cable hangers, CAB- 9760. Id. And as explained in the analysis above, all of these parts were known and available in the prior art, as evidenced by the CAB Website and the CAB Whitepaper. We can discern no nexus between the features of the ’551 patent and the alleged objective evidence of nonobviousness given that the so-called “Integrated System” includes multiple, interchangeable, and “exemplary” part numbers that were known in the prior art. See Yita LLC v. MacNeil IP LLC, 69 F.4th 1356, 1364 (Fed.

We agree with Petitioner that the preambles of claims 1 and 6 recite an intended use. The bodies of both claims recite a structurally complete system comprising a messenger wire and a plurality of cable hangers that are disposed along and suspended from the messenger wire and have a plurality of cable carrying surfaces structured to support at least one electrical cable of the plurality of electrical cables and are separated by a cable carrier divider. Ex. 1001, 10:27–37. According to the preambles, the system are used “for organizing a plurality of electrical cables extending from a plurality of solar panels.” Id. at 10:24–26. slip op. at 9

    “Petitioner asserts that Patent Owner’s construction “only replaces ‘organizing’ with ‘separating’” and “organizing” has a broader ordinary meaning than separating and includes “to arrange or order” not merely to separate. Reply 4 (citing Exs. 1052, 1053); id. at 5 (“Separated cables may be organized. But not all organized cables are necessarily separated.”). We adopt Petitioner’s interpretation of “organizing” as “to arrange or order.” Reply 4. This meaning is consistent with the preamble language of “[a] system for organizing a plurality of electrical cables extending from a plurality of solar panels” comprising a messenger wire and cable hangers disposed along and suspended from the messenger wire with cable carrying surfaces that support electrical cables separated by a divider. Ex. 1001, 10:24–37. The system organizes electrical cables by (1) suspending them from a messenger wire on cable hangers, (2) supporting the cables on cable carrying surfaces of each cable hanger, and (3) separating the cables on adjacent cable carrying surfaces of the cable hangers by using a divider. The “organizing” in the preamble encompasses each of these ways of arranging or ordering the electrical cables but is not limited to any particular way of doing so and merely recites an intended use of the systems. Because we interpret the preamble as reciting an intended use of the systems, we also interpret this portion of the preamble as an intended use of those systems. Our Decision would be the same under Patent Owner’s interpretation that organizing means separating because the combination of Almy and Carr renders obvious a system for organizing electrical cables extending from solar panels by suspending them from a messenger wire on cable hangers that also separate the cables, as discussed infra in Section II.D.

In view of these disclosures, we credit the testimony of Dr. Kiaei that one of ordinary skill in the art would have sought to use Holmberg’s wall box in multi-dwelling units and would have seen a need to access the area behind spice tray 230 to connect and disconnect subscribers. Ex. 1003 ¶ 92; Ex. 1033 ¶¶ 7–8. Moreover, even if Holmberg were limited to mid-span locations and distributing drop cables, as opposed to distribution cables for individual subscribers, as asserted by Patent Owner, Patent Owner does not dispute that a technician would still need periodic access to the area behind splice tray 230 in these mid-span devices.

Thus, whether used in the manner contemplated by Petitioner or Patent Owner, Petitioner persuasively demonstrates that access to the space behind splice tray 230 in Holmberg would be necessary.

  • Patent Eligibility (§101) › Alice/Mayo step two — inventive conceptStep2 no inventive conceptUnpatentable

    “The ordered combination of elements recites no more than when the elements are considered individually and thus does not provide an inventive concept. We disagree with Patent Owner’s argument that “[w]hen considered individually or in combination with the other claimed elements, the reliance on this merged data from a camera and LIDAR/RADAR sensor is itself an inventive concept because it was not conventional and improves the technology of aircraft tracking and guidance.” PO Resp. 49–50. Merging data from two different sensors is part of the abstract idea and therefore cannot provide an inventive concept that makes that abstract idea patent eligible. See, e.g., BSG, 899 F.3d at 1291–92; Guidance at 56. “If a claim’s only ‘inventive concept’ is the application of an abstract idea using conventional and well-understood techniques, the claim has not been transformed into a patent-eligible application of an abstract idea.” BSG, 899 F.3d at 1290–91. “It has been clear since Alice that a claimed invention’s use of the ineligible concept to which it is directed cannot supply the inventive concept that renders the invention ‘significantly more’ than that ineligible concept.” Id. at 1290. Even if merging camera and LIDAR/RADAR sensor data is treated as an additional element, the description of the point cloud process and iterated point cloud algorithm indicates Patent Owner did not invent or improve the merging process. Ex. 1001, 8:64–9:40; MPEP § 2106.05(d)I.2. (a generic description indicates that elements are conventional enough that no further description is needed to satisfy § 112(a)); see AI Visualize, 97 F.4th at 1379 (converting data from one format to another is an abstract idea); Adaptive Streaming Inc. v. Netflix, Inc., 836 F. App’x 900, 903 (Fed. Cir. 2020) (encoding and decoding image data and converting data formats are abstract ideas). Dr. Campbell and Mr. Wilson testify that merging data is known for detecting and tracking objects and navigation. Ex. 1044 ¶¶ 41–51, 56–59; Ex. 1003 ¶¶ 54–65, 81–87; Ex. 1045, 20:6–23:18. A “data fusion process” is not claimed, much less one of any particular features. See PO Resp. 50. Nor do the claims recite a non-conventional arrangement of sensors. See Ex. 1003 ¶¶ 42–67, 83; iLife, 839 F. App’x at 538 (because sensors for measuring static and dynamic acceleration were known, and claim 1 did not recite unconventional means for processing that data, sensing and processing the static and dynamic acceleration information using generic components did not transform the nature of claim 1 into patent eligible subject matter).” slip op. at 39

See Thorner v. Sony Entm’t Am. LLC, 669 F.3d 1362, 1366 (Fed.

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner

    “art would not have modified Kurita in view of Lemoff because Lemoff positions the signal emitters near the fiber to emulate WDM without the need for an external optical multiplexer or a similar device and discourages using optical wavelength multiplexers for short distances because the complexity of the design is often cost prohibitive (PO Resp. 47–48), Lemoff does not appear to limit the usefulness of the fiber connector to any particular optical signal transmission distance. Petitioner relies upon Lemoff for a suggestion to combine Lemoff’s fiber connector configuration teachings with Kurita’s multiplexer teachings to enable fibers to be plugged Fig. 2) (Pet 29, 31; Reply 17–18). Regarding Patent Owner’s argument that one of ordinary skill in the art would not have combined Lemoff’s receptacle and ferrule with discrete components in Kurita because the fiber would need to be manually fixed and aligned with or without a ferrule and, therefore, would serve no purpose (PO Resp. 48), Lemoff’s fiber connector appears to fix and align the fiber adequately for wavelength division multiplexing without manual fixation or alignment being required (Ex. 1006, 5:65–6:2, Fig. 2; Reply 18). The challenged claims do not require any greater degree of fixing and alignment than that provided by Lemoff’s fiber connector. Regarding Patent Owner argument that Lemoff’s device is not physically combinable with Kurita’s WDM multiplexer due to Lemoff’s device’s small size (PO Resp. 47–48; Reply 17–18), “[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” (In re Keller, 642 F.2d 413, 425 (CCPA 1981)). Accordingly, we are not persuaded by Patent Owner’s argument.” slip op. at 26

    “stopped single optical fiber because fixing it in place does not passively align it with the optical components (PO Resp. at 35–37) is not persuasive because fixing Kurita’s fiber (40) in place in accord with Lemoff’s teaching regarding the ferrule (255) inserted until being stopped by the receptacle (260) (Ex. 1006, 5:50–6:15, Fig. 2) would align Kurita’s optical array (20), and lens (30)) (Ex. 1004 Fig. 3) passively in the same manner that Lemoff’s ferrule (255), after being inserted until stopped by the receptacle (260), passively aligns the optical fiber (250) with the optical components (optical imaging element 220 and light emitters within emission apertures 120) (Ex. 1006, 5:50–6:15, Fig. 2; Reply 15–16). Regarding Patent Owner’s argument that the light from each of Kurita’s lasers (11) depicted in Figure 3 cannot pass through a separate focusing lens (30) pie shaped sector because the lasers (11) and collimating lenses (21) are arranged linearly rather than being arranged about a circular axis (PO Resp. at 37–42), we do not agree. Claim 1 requires “focusing means having n separate radial sectors on its surface, and each of said n collimated beams passes through a separate one of said n sectors of said focusing means” (Ex. 1001, 5:34–37), claim 2 requires “four lasers and four collimating lenses are each formed in a two-dimensional, two by two array [centered on the focal axis of lens 30], wherein said focusing means is a single focusing lens, and wherein each radial sector is a pie-shaped quadrant” (id. at 5:41–44), and claim 7 requires “focusing means having four separate quadrants on its surface, and each of said four collimated beams passes through a separate one of said quadrants of said focusing means” (id. at 6:35–38). Kurita meets those claim requirements. Kurita’s two by two array (10A) of lasers (11), collimating lens (21) array (20), and focusing lens (30) are shown in Kurita’s Figure 3 (cropped) as follows: The image is a portion of Kurita’s Figure 3 showing Kurita’s laser array, collimating lens array, and focusing lens (30). Relative to a point at the center of the laser array (10A) or the collimating lens array (20), each laser (11) and each collimating lens (21) is in a separate quadrant that can be a quadrant of a circle (pie-shape) on lens 30 (Reply 12– 13, Ex. 1003 ¶¶ 85–91).” slip op. at 23
