  • 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.

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.

    “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”). Like the patent owner in Fox Factory, “[i]n light of the patentee’s own assertions about the significance of the unclaimed features, no reasonable fact finder could conclude that these features are insignificant.” Fox Factory, 944 F.3d 1375. As a result, the patent claims are not coextensive with the CoinPower® products because those products include “‘critical’ unclaimed feature[s] that [are] claimed by a different patent and materially impacts the product’s functionality.” Id.” slip op. at 40

    “Patent Owner does not challenge directly Mr. Occhiogrosso’s testimony. See generally PO Resp. 5. Mr. Ivan Zatkovich, Patent Owner’s declarant, does not propose a level of ordinary skill in the art to be adopted, but he does testify that the opinions set forth in his declaration would not change if he “assumed that [one of ordinary skill in the art] had the qualifications set forth in Mr. Occhiogrosso’s declaration.” Ex. 2098 ¶ 24 (citing Ex. 1008 ¶ 27). Having reviewed the prior art asserted in this proceeding (see, e.g., Exs. 1002–1005), we determine that the level of ordinary skill proposed by Petitioner’s declarant and employed by both declarants is consistent with the challenged patent and the referenced prior art, and we adopt Mr. Occhiogrosso’s definition of the level of ordinary skill in the art for the purposes of the analysis below.” slip op. at 11

    “Turning to the merits of the Motion to Exclude, we find Patent Owner’s assertion that a person of ordinary skill in the art “must know the relevant prior art of telephone technology for the deaf and HOH” (Mot. Exc. 4) lacks sufficient factual corroboration or explanation. For example, Patent 10 Mr. Zatkovich is referring to the level of ordinary skill discussed previously and which we adopted for this proceeding. 14 Owner does not address the sentence that immediately precedes the single citation in the challenged patent on which Patent Owner relies: “[t]he present invention relates to the general field of telephone communications.” Ex. 1001, 1:13–14. Nor does Patent Owner discuss the level of ordinary skill reflected in the prior art of record or other factors that may be considered, including the types of problems encountered in the art, the sophistication of the technology, and educational level of active workers in the field. Okajima, 261 F.3d at 1355. Even if we were to adopt Patent Owner’s definition of a person of ordinary skill in the art, we find Mr. Occhiogrosso meets Patent Owner’s proffered level of ordinary skill: “must know the relevant prior art of telephone technology for the deaf and HOH” (Mot. Exc. 4). Mr. Occhiogrosso’s experience providing expert testimony in proceedings regarding assistive technologies for the deal or hard of hearing is uncontroverted. See Mot. Exc. 4–5 (identifying three inter partes reviews); Ex. 2105, 5:23–6:10 (deposition on August 9, 2016 indicating Mr. Occhiogrosso has been deposed between twelve and twenty times concerning Patent Owner’s patents). Furthermore, the five prior art references Mr. Occhiogrosso considered for this case (Ex. 1008 ¶ 28) all involve telephone technology for the deaf and HOH and support his qualification under the definition of a person of ordinary skill in the art now offers for the first time in its Motion to Exclude (and after it relied on the testimony of its declarant as to a different level). 15” slip op. at 14

    “Mr. Occhiogrosso testifies that one of ordinary skill in the art “would consider the screen in Figure 6 [shown on a cellular phone] as analogous to the screen depicted in Figure 8.” Ex. 1043 ¶ 6; see Pet. Reply 9–10 (citing Ex. 1043 ¶ 4–7). Mr. Occhiogrosso’s testimony relies on, and better comports with, Liebermann’s description of Figure 8 as illustrating “a layout for the visual display to present multiple information to the deaf person.” Ex. 1002, 6:29–36; Ex. 1043 ¶ 6. Mr. Occhiogrosso opines that the layout in Figure 8 “can be applied to different devices with displays of varying dimensions,” including the cellular embodiment of Figure 6, the personal computer embodiment in Figure 5a, and the kiosk embodiment in Figure 5c. Ex. 1043 ¶ 6. Mr. Occhiogrosso explains that Figure 8 depicts a “three-part, logical screen layout [that would be] identical and would be scaled appropriately, depending on display size.” Id. We credit Mr. Occhiogrosso’s testimony over that of Mr. Zatkovich because Mr. Occhiogrosso’s testimony better comports with the express disclosure of Liebermann—Figure 8 is not described as being limited to the embodiments in Figures 5a–5c or otherwise not being applicable to the cellular phone embodiment shown in Figure 6. Rather, Figure 8 is described more generally as being “a layout for the visual display.” Ex. 1002, 6:31– 34 36. In addition, Mr. Zatkovich opines that one of ordinary skill in the art purportedly would not incorporate the display shown in Figure 8—that is, the three-part display. At issue here, however, is only a small portion of that display—the incoming text screen—showing the text communication representing a transcription of the voice of the person speaking to a user of the personal interpreter device.” slip op. at 34

    “skill in the art would combine Aronow’s initiation switch into Liebermann’s device to save power. PO Resp. 35–36. We agree with Patent Owner that, because the initiation switch is not an “on/off switch” that would enable a user to turn off the device and save power, Mr. Occhiogrosso’s power saving rationale (Ex. 1008 ¶¶ 58–59) is an insufficient motivation to combine the initiation switch. PO Resp. 35–36 (citing Ex. 2098 ¶ 62; Ex. 2097, 141:21– 142:12). Similarly, we also agree with Patent Owner’s challenge regarding Mr. Occhiogrosso’s testimony that Aronow’s switch improves Liebermann’s communicator by making it a “low cost, self contained telephonic interface device requiring no programming for operation.” Id. at 36. Relying on Mr. Zatkovich’s testimony, Patent Owner indicates “the communicator/cellular phone embodiment of Fig. 6 of Liebermann[] already appears to be a self-contained device.” Id. (citing Ex. 2098 ¶ 61). Nevertheless, we note that there is no dispute that Liebermann’s communicator and cellular telephone implementations provide for a user initiating a call to the center by dialing the center. See, e.g., PO Resp. 36 (“As a special case of a telephone, Liebermann can initiate a call simply by dialing a stored number to the Center.”). We disagree with Patent Owner that the addition of Aronow’s switch would not simplify the communicator 48 of Liebermann. Id. Common sense suggests that a single initiation switch is a simpler way to initiate a call than by dialing the multiple digits of a telephone number. Furthermore, we credit Mr. Occhiogrosso’s testimony of the simplifying benefits of a user-operated initiation switch, which is based on Aronow’s discussion about the benefits of the initiation switch to simplify operations of the telephonic device, especially for elderly people who are hard of hearing. Ex. 1008 ¶ 58. For these reasons, we determine that Petitioner has provided sufficient” slip op. at 48

Thus, Patent Owner is offering the statement for the truth that voice and re-voiced text gives the phone back to folks with hearing loss. Patent Owner’s argument that Mr. Puzey was discussing the existence of features in his company’s product rather than features in Patent Owner’s product does not change that his statement is offered as proof regarding an alleged long-felt need for the features.
