  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “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). Upon review of the evidence of record and the parties’ arguments, we adopt Petitioner’s definition of the person of ordinary skill in the art as it is consistent with the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (holding that the prior art itself can reflect the appropriate level of ordinary skill in the art). We note, however, that the conclusions reached in this Decision would be the same under either proposed definition of the ordinarily skilled artisan. See Ex. 2009 ¶ 83 (Dr. Schubert testifying that his opinions would be the same under either proposed definition); Ex. 1033 ¶ 9 (Dr. Shealy testifying that the differences in proposed definitions of the ordinarily skilled artisan “would not change the outcome of the invalidity analysis in any material manner”); PO Resp. 7; Pet.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

    “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

    “On this issue, we agree with Petitioner. Mr. Gardner explains that the skilled artisan “would further recognize that the output conductor can be comprised of various materials . . . . which could be metal or various materials . . . . [and] the shape of the output conductor is not particularly limited.” Ex. 1003 ¶ 322. Mr. Gardner further testifies that a person of ordinary skill in the art “would recognize, not only that metal foil conductors could be inserted into these grooves without difficulty, but also that the depth of the grooves can be altered in order to better accommodate metal foil output conductors.” Ex. 1041 ¶¶ 53, 70. We recognize Patent Owner’s argument that numerous factors must be considered and that conventional battery design does not necessarily translate to button cell designs (PO Resp 25–26), but as Mr. Gardner testifies, “this may be true in some cases, [but] the lessons and advantages of using techniques from conventional battery design and applying it to button cell would be obvious to a [person of ordinary skill in the art].” Ex. 1041 ¶ 103. He continues to explain that “[n]aturally, such transposition of techniques would require some modification and adjustments. . . . [and that] each of these adjustments, . . . would be well within the skill of a [person of ordinary skill in the art].” Id. ¶ 104 (describing, for example, “reducing the thickness of the conductor plates of Kobayashi”). We credit Mr. Gardner’s testimony. Moreover, Patent Owner does not allege that any proposed modification would be beyond the skill of a person of ordinary skill in the art or explain how any of the “constraints unique to . . . button cell design” (PO Resp. 25) are relevant to the proposed substitution of a metal foil for a metal terminal electrode plate. See generally id.; Sur-reply. Finally, Patent Owner argues that “[r]eliance upon the general knowledge of a [person of ordinary skill in the art] to provide a missing element in a combination of references is an exception rather than the rule” and “is particularly true where the proposed modification goes to the essence of the claims.” PO Resp. 26. Patent Owner states that “Petitioners have provided no more than ‘conclusory statements and unspecified expert testimony’ to supply a metal foil that is admittedly missing from Kobayashi, and is not shown in any other button cell art.” Id. at 27. We disagree. As the Federal Circuit has explained ‘common sense and common knowledge have their proper place in the obviousness inquiry,’ (a) invoking ‘common sense . . . to supply a limitation that was admittedly missing from the prior art’ should generally only be done when the [missing] limitation in question [is] unusually simple and the technology particularly straightforward;’ and (b) references to common sense ‘cannot be used as a wholesale substitute for reasoned analysis and evidentiary support’ Koninklijke Philips N.V. v. Google LLC, 948 F.3d 1330, 1338 (Fed. Cir. 2020)(quoting Arendi S.A.R.L v. Apple Inc., 832 F.3d 1355, 1361–1362 (Fed. Cir. 2013)). Here, Petitioner proposes to substitute a metal foil for a metal terminal electrode plate to provide contact with the inner surface of the button cell housing. Ex. 1006 ¶ 34. As detailed above, Petitioner and Mr. Gardner direct our attention to the prior art of record which suggests use of foil within small battery cells to provide electrical contact was well-known and explains why the skilled artisan would have reduced the thickness of the terminal electrode plate to maximize the available space for active electrode components. Accordingly, unlike the expert in Arendi, Petitioner here provides more than “conclusory statements and unspecific expert testimony.” Arendi, 832 F.3d at 1366.” slip op. at 22

    “that “Kaun discloses that the cell is sealed ‘by a ‘U’ shaped insulator/gasket 32 . . . to seal the cell without pressure-loading,’” and therefore, venting via a pressure release seal is not required. Pet. 64 (citing Ex. 1005 ¶ 120). In an alternate embodiment, Kaun provides a means to relieve gas pressure “via the peripheral gasket which can reseal after an event.” Ex. 1005 ¶ 91. As Petitioner explains, “Kaun discloses that it is sealed, but upon the application of certain conditions, the internal pressure of gases within the cell can cause gases to vent. During such events, Kaun discloses ‘[t]he specified limit for internal pressure is handled by release via the peripheral gasket which can reseal after an event.’” Pet. Reply 13 (citing Ex. 1041 ¶¶ 37–39; Ex. 1005 ¶¶ 91, 101). Thus, while Kaun discloses venting to prevent pressure build up, Kaun “is otherwise sealed at all times during functioning.” Id. (citing Ex. 1041 ¶¶ 38–39; Ex. 1005 ¶ 101). Neither the ’835 patent nor Patent Owner’s own proposed construction of “closed without being beaded over” requires closure at all times. Furthermore, Mr. Gardner testifies that “[i]f a battery which, upon application of significant internal pressure, would be considered not ‘closed’ at other times, th[e]n almost no battery could be considered closed. [Because] [a]ny battery, when subjected to certain pressures, would leak or burst.” Ex. 1041 ¶ 39. We credit Mr. Gardner’s undisputed testimony in this regard. Mr. Gardner reasons that a person of ordinary skill in the art would understand that Kaun is closed.” Id. Dr. Peckerar similarly testifies that Kaun shows a housing that is closed without being beaded over. Ex. 1034, 131:4–11; 237:19–238:22 (describing Kaun as “closed during normal operation”).

    “Thus, Patent Owner identifies three claimed features—i.e., the jelly- roll configuration, the insulating layer, and a housing closed without being beaded over—as responsible for the improved performance of the VARTA CoinPower® button cell batteries. Id. However, Patent Owner’s declarants testify further and explain that it is the combination of the three identified features, in addition to a flat foil conductor resting flat between the electrode top and housing and welding the foil conductor from outside the housing, that are responsible for improved performance. In particular, Mr. Miehlich, employed in VARTA’s marketing and sales department, testifies that the new cell design, which “provided unprecedented increases in performance, including in energy density, charge capacity, and cycling stability,” consisted of a “jelly roll electrode coil packed tightly into an uncrimped, button-like housing. The electrode coil was protected against short-circuiting by [an] insulating means, and was connected to the cell terminals by a flexible flat foil conductors resting flat between the electrode top and housing, and welded to the housing components from the outside. These features are all found in the claims of the VARTA patents here under review. Ex. 2045 ¶¶ 15–16. And, Dr. Lindner, one of the named inventors of the ’835 patent, testifies that the complex issues we faced were how to safely pack the required amount of electrode material into the very small “button”-sized housing and protect it against short circuits; how to connect the “jelly roll” electrode to the terminals in such a confined space without itself consuming much volume, and how to seal the top and bottom of the cell housing, all while accommodating the expansion and contraction of the electrode winding and the resulting mechanical forces. Ex. 2046 ¶ 33. According to Dr. Linder, the jelly-roll configuration with an insulator, flexible foil output conductors, sealing the cell without crimping, and welding the foil conductors from outside the housing each contributed to the improved battery performance. Id. ¶¶ 34–43. Thus, it is the combination of five elements—not the three claimed in the ’835 patent—that are purportedly responsible for the “vastly increased performance characteristics” of the CoinPower® products. Id. ¶ 43; see also id. ¶ 45 (noting that “various aspects of our invention are covered by 10 issued patents, including the four United States patents here under review” (emphasis added)); Tr. 84:24–85:10 (explaining that welding, for example, is “also part of the success”).

    “We are not persuaded that the identified portions of Mr. Gardner’s Supplemental Declaration are improper. In the Petition, Petitioner alleged that a person of ordinary skill in the art would have had reason to substitute known metal foils for the metal conductor plates of Kobayashi in order to reduce the size of inactive materials and improve performance. Pet. 31 (citing Ex. 1003 ¶ 323). In its Response, Patent Owner argued, among other things, that the metal foil lacks the requisite rigidity to support the remaining components of the winding axis core (PO Resp. 22–27, 31), and that because metal connecting plates 4a and 5b are positioned within recesses of insulating plates 8 and 9, replacing the metal connecting plates with metal foils would result in an unreliable connection because the metal foil would become embedded within the grooves of the insulating plates (id. at 28, 31). Mr. Gardner’s supplemental testimony specifically addresses Dr. Peckerar’s and Patent Owner’s concerns that metal foils would be unsuitable in Kobayashi due to their flexibility and thickness as compared to the insulating plates. Ex. 1041 ¶¶ 53 (“the depth of the grooves can be altered in order to better accommodate metal foil output conductors”), 70, 71 (explaining that it is the winding core that provides structure not the output conductor plates), 81, 86 (explaining that the person of ordinary skill in the art could either adjust the size of the output conductors or the depth of the cavities themselves), 87. Therefore, Mr. Gardner’s testimony that the ordinarily skilled artisan would have understood how to account for the technical challenges Patent Owner identified properly responds to arguments raised by Patent Owner in its Patent Owner Response. Accordingly, we deny Patent Owner’s Motion to Exclude Mr. Gardner’s testimony regarding Kobayashi’s modified electrode assembly.” slip op. at 11

    “Upon review of Petitioner’s arguments and supporting evidence, we find that Petitioner adequately shows that a person of ordinary skill in the art would have modified Kobayashi to include metal foils in place of its terminal electrode plates. Petitioner explains that one of ordinary skill in the art would have known that metal foil may be used in batteries because the use of metal foil as a conductor is common in the art. Pet. 31, 39 (citing Ex. 1003 ¶¶ 256, 323). Petitioner directs our attention to Kobayashi which details use of metal foil for conducting elements. Id. at 39; see also Ex. 1006 ¶¶ 7, 21, 26, 27 (describing metal foil electrodes). Furthermore, Mr. Gardner testifies that “reducing the thickness of the output conductors has the effect of reducing the ratio of inactive to active components within the cell, which improves energy density . . . . [and is] a well-known goal in the art.” Ex. 1003 ¶ 323. Mr. Gardner further opines that a person of ordinary skill in the art “would be motivated to reduce the thickness of the output conductors of Kobayashi in order to increase energy density within the cell” and “to use metal foils as the output conductors, as this furthers the well-known goal in the art of reducing the size of internal battery components.” Id. We acknowledge Patent Owner’s argument that Mr. Gardner relies on teachings related to conventional battery design—not button cell batteries—and that he discusses considerations “relating to thickness of the electrodes, not of output conductors.” PO Resp. 19–20. But, Mr. Gardner’s testimony similarly relies on passages directed to “basic concepts” of battery operations and, as a whole, focuses on the concept that reducing the thickness of the terminal electrode plates would “maximize the space available inside the cell for active components,” thereby increasing electrode density and improving battery performance. Ex. 1003 ¶ 323 (citing Ex. 1009, 35). According to Mr. Gardner, “these adjustments would be well within the skill of a [person of ordinary skill in the art].” Ex. 1041 ¶¶ 104. We credit Mr. Gardner’s testimony. “Moreover, if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond that person’s skill.” KSR, 550 U.S. at 401.” slip op. at 21

  Claims 1–24 are unpatentable under § 103; proposed substitute claims 25–28 are patentable and entered because the prior art did not motivate the claimed 5,000–8,000 w-ppm sulfur range.

    “Based on the record before us, we conclude that Neste has carried its burden of demonstrating that claim 25 is patentable over the prior art of record. We concluded above, in discussing the original claims, that a person of ordinary skill in the art would have had reason to combine Jakkula and Monnier I to add sulfur to the feedstock of an HDO process that is followed by an HI step, because the prior art suggests that concentrations of 2000 or 4431 w-ppm have beneficial effects on catalyst activation and decarboxylation selectivity. A person of ordinary skill would, therefore, weigh the possible deleterious effects of sulfur on the HI catalyst, against the 28 possible benefits. The question of whether a person of ordinary skill in the art would have had reason to add an even higher concentration of sulfur—in the range of 5000–8000 w-ppm—is an altogether different one. The record before us does not establish persuasively that there was any art-recognized benefit to using a concentration of sulfur over 4431 w-ppm. Absent any indication of a benefit to be obtained from adding even greater amounts of sulfur, the skilled artisan would have no reason to make the modifications to Jakkula necessary to result in the claimed invention. Such modifications would involve catalyst replacement costs, additional processing steps such as stripping, or catalyst substitutions18 that—although not prohibitive if the prior art suggested a benefit might be obtained—would not be undertaken if the person of ordinary skill saw no benefit to making them. For these reasons, we conclude that Neste has established sufficiently that there was no reason to modify the prior art to arrive at the process of claim 25.” slip op. at 28

    “We are not convinced by REG’s rate constant argument. First, REG does not direct us to any evidence in the record, other than the testimony of Dr. Sughrue, that establishes that increasing the rate constant of the conversion reaction was recognized in the art to be beneficial. This is in stark contrast to decarboxylation selectivity, which is described by several 17 Furthermore, as discussed above with respect to Laurent I, we do not find such a significant increase in sulfur concentration—from 2000 to 5000–8000 w-ppm—to be “routine.” 26 references as decreasing hydrogen consumption and, therefore, processing cost. We are, therefore, left with only Dr. Sughrue’s statement that an “increase in rate constant is important because a higher activity allows for less catalyst to be used to deoxygenate the feedstock.” Ex. 1043 ¶ 125. Dr. Sughrue cites no support for such an assertion, and we accord it little weight. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). Second, we note that Table 4 of Laurent II reports, along with kDES, the rate constants k4MA and kGUA, pertaining to the HDO conversion of 4- methylacetophenone and guaiacol, respectively. Ex. 1011, 107. While kDES is shown to increase with sulfur concentration, k4MA decreases and kGUA is unaffected by sulfur concentration. Id. REG provides no evidence or argument establishing why a person of ordinary skill in the art would have considered only the kDES rate constant in determining the benefit of increased sulfur concentration.” slip op. at 26
