  • 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.

    “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

    “meaning in the art. See Irdeto Access, Inc. v. Echostar Satellite Corp., 383 F.3d 1295, 1300 (Fed. Cir. 2004) (stating that, absent an accepted meaning in the art, “we construe a claim term only as broadly as provided for by the patent itself”). Thus, we must attempt to discern the meaning of this term from the claim language itself and from the remainder of the intrinsic record. See Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996) (“It is well-settled that, in interpreting an asserted claim, the court should look first to the intrinsic evidence of record, i.e., the patent itself, including the claims, the specification and, if in evidence, the prosecution history.”). Upon review of the parties’ arguments and the intrinsic record, we agree with Petitioner that the ’702 patent does not support a construction of “stackable add-on layer” that encompasses memory cells formed by sequential deposition on a substrate without being formed and then added to a separately formed substrate.” slip op. at 10

    “As discussed above, we construe “stackable add-on layer” to not include memory cells that are formed by sequential deposition on or above a substrate without being added to a separately formed substrate. It is undisputed, and indeed it is Petitioner’s assertion, that Lee’s memory devices are formed by sequential deposition. See Pet. 52 (asserting that in Lee “the layers of the array are directly deposited on the layers of each underlying level, and the array is deposited on the interlayer insulating layer formed over a substrate”); see also id. at 70 (“Lee discloses forming vertical memory devices through layer-by-layer sequential deposition on the substrate . . . .”). Therefore, Petitioner does not show that Lee discloses every limitation of independent claim 13 under our claim construction. Thus, Petitioner does not demonstrate by a preponderance of the evidence that claim 13 would have been obvious in view of Lee. 3. Claims 14 and 15 Claims 14 and 15 depend from claim 13. Ex. 1001, 12:35–42. Petitioner’s arguments for these claims do not remedy the deficiencies noted above with respect to independent claim 13. Pet. 54–59. Accordingly, Petitioner does not demonstrate by a preponderance of the evidence that claims 14 and 15 would have been obvious in view of Lee alone. E. Claims 16 and 17 over Lee and Endoh Petitioner contends the subject matter of claims 16 and 17 would have been obvious over the combined disclosures of Lee and Endoh. Pet. 59–69. Petitioner’s arguments with respect to these claims, however, do not remedy the deficiencies noted above with respect to Lee and its monolithic, sequentially deposited memory array. Accordingly, Petitioner does not demonstrate by a preponderance of the evidence that claims 16 and 17 would have been obvious over Lee and Endoh.” slip op. at 18

    “combined Lee and Watanabe to achieve improved integration density. Pet. 71. Petitioner concedes, however, that the benefits of Lee’s design related to 3-D integration and improved integration density would be obtained if Lee’s memory structures are formed using either Lee’s monolithic construction method or Watanabe’s alternative stacking method. Pet. Reply 13–14 (citing Ex. 1041 ¶ 34). Thus, we are not persuaded that improved integration density provides a sufficient rationale for Petitioner’s combination of Lee’s memory device and Watanabe’s stacking method. Petitioner argues that Watanabe’s stacking method “improves the accuracy of the wiring” because the wiring is made “for each planar member.” Pet. 72 (citing Ex. 1005, 6:1–3). Watanabe also states that its disclosed methods provide “a low interconnection wire resistance.” Ex. 1005, 6:20–23. Petitioner does not, however, explain sufficiently how Watanabe’s stacking method would improve Lee’s device. For example, Petitioner does not address whether the alleged wiring benefit already existed in Lee’s monolithic array or explain how this benefit would also apply to Lee’s particular memory array, which differs in construction and elements from Watanabe’s device. This diminishes Petitioner’s benefits-based motivation to combine arguments. In general, a petitioner need not demonstrate that a particular alternate method would improve a prior art device in order to show a motivation to combine. Intel Corp. v. PACT XPP Schweiz AG, 61 F.4th 1373, 1380–81 (Fed. Cir. 2023); see Pet. Reply 20 (citing Intel). But here, Petitioner affirmatively invokes improvement of Lee’s device as a reason for the combination, and we must evaluate Petitioner’s contention. Moreover, any relative lack of improvement or benefits must be weighed against any problems the alternative method would introduce. See Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 795–96 (Fed. Cir. 2021) (noting that simultaneous advantages and disadvantages to a proposed combination must be analyzed to determine whether the disadvantages “outweighed any reason to combine”). Here, as discussed above in more detail with respect to the ground based on Watanabe, the evidence shows that one of ordinary skill in the art would have expected Watanabe’s bonding temperature of 900– 1000° C to damage the electronic devices in an underlying substrate. Ex. 2029 ¶¶ 75–76; Ex. 2028, 123:13–124:7; Ex. 2027, 715. The expected damage to Lee’s device, when balanced against the limited evidence of a benefit to the combination,7 outweighs the reason to combine Lee and Watanabe set forth in the Petition. Accordingly, Petitioner does not demonstrate by a preponderance of the evidence that claim 13 would have been obvious over Lee and Watanabe. 2. Analysis – Claims 14 and 15 Claims 14 and 15 both depend directly from independent claim 13. Ex. 1001, 12:35–42. Petitioner’s arguments with respect to claims 14 and 15 do not remedy the deficiencies noted above with respect to independent claim 13. Pet. 73. Accordingly, Petitioner does not demonstrate by a preponderance of the evidence that these claims would have been obvious over Lee and Watanabe.” slip op. at 40

    “We credit the testimony of Dr. Przybylski that one of ordinary skill in the art would have understood that Watanabe’s stacked structure would be severely impacted if bonded at a temperature above 900° C, as disclosed in Watanabe. Ex. 2029 ¶¶ 76–77. Dr. Przybylski’s opinion is supported by Dr. Lee’s testimony (Ex. 2028, 123:13–124:7, 125:6–126:7), as well as Watanabe (Ex. 1005, 6:6–14) and Batude (Ex. 2027, 715). As further discussed below, we find that Petitioner has not rebutted Patent Owner’s showing of nonenablement, and Patent Owner has carried its burden to demonstrate that Watanabe was not enabled for bonding temperatures of 900–1000° C, as of the 2004 filing date of the ’702 patent.” slip op. at 32

    “II. TIMELINESS OF THE PETITION UNDER 35 U.S.C. § 315(B) Pursuant to 35 U.S.C. § 315(b), “[a]n inter partes review may not be instituted if the petition requesting the proceeding is filed more than 1 year after the date on which the petitioner, real party in interest, or privy of the petitioner is served with a complaint alleging infringement of the patent.” Patent Owner argues that the Petition is untimely under 35 U.S.C. § 315(b) because Petitioner is in privity with time-barred entities. Prelim. Resp. 10– 30. However, 35 U.S.C. § 315(b) also provides that the one-year time bar “shall not apply to a request for joinder under subsection (c).” See also 37 C.F.R. § 42.122(b).

Prelim. Resp. 8. Patent Owner summarizes this dispute as follows: The challenged patent discloses and claims a semiconductor device with (among other things) a “drift layer having a graded concentration of dopants . . . [and] further having a first static unidirectional electric drift field to aid the movement of minority carriers.”[] The Petition should not be instituted, because (among other deficiencies) it fails to show that the prior art discloses the “aid the movement of minority carriers” claim limitation. Rather than pointing to anything in the prior art that would teach this claim limitation, the Petition assumes that any “graded concentration of dopants” would necessarily “aid the movement of minority carriers.” The Petition contains no analysis explaining why the “graded concentration of dopants” in the prior art meet the “aid the movement of minority carriers” limitation, apart from the fact that they are “graded concentration of dopants.” In other words, Petitioner reads the “aid the movement of minority carriers” limitation out of the claims completely.

  • Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateWritten description adequateMixed

    “Ex. 2027, 20:25–21:5 (emphasis added). The disclosure that the “magnesium composite” of “[t]he present invention” “includes at least 50 wt% magnesium” is unambiguous and constitutes strong evidence that the inventors were not in possession of a magnesium composite with less than 50 wt. % magnesium, or additive concentrations above 50 wt. %. See SciMed Life Systems, Inc. v. Advanced Cardiovasular Systems, Inc., 242 F.3d 1337, 1343 (Fed. Cir. 2001) (noting that a description of the “present invention” as having a particular structure “is strong evidence that the claims should not be read to encompass the opposite structure”). Consistent with this conclusion, the original claims of the ’295 application all limited the additive material in the composite to 0.05 wt %–45 wt %. Ex. 2027, 26:1– 13, 29:9–15. Likewise, in each example where copper, nickel, or cobalt additives are used in the range recited in the proposed substitute claims, the magnesium composite is “over 50 wt% magnesium,” and any claims that do not require this range of magnesium are limited to an additive range of “about 0.05 wt%–45 wt% of said mixture.”8 Ex. 2027, 6:13–7:4, 7:16–19, 8 Written description support is considered from the view point of the ordinarily skilled artisan. Ariad Pharms., Inc. v. Eli Lilly and Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). Patent Owner, bearing the burden to show written description support in any priority application for which it seeks the benefit of its filing date, provides no testimony from an ordinarily skilled artisan regarding written description support in the ’295 application, or any evidence to show what such an artisan would conclude from the express disclosures of the ’295 application. Lectrosonics, Paper 15 at 7; In re NTP, 654 F.3d 1268, 1276 (Fed.

Where there is any ambiguity in the disclosures of the ’295 application, the absence of supporting testimony tends to cut against 26:2–31:2; see Ex. 1005 ¶¶ 12, 13, 18, 19, 16–21, 26, 28, claims 16–21, 26– 28.

As proposed substitute claim 104 encompasses a magnesium cast composite with up to 90 wt. % additives, and therefore as little as 10 wt. % magnesium, Patent Owner has not demonstrated that the full scope of this claim finds written description support in any application prior to the ’915 application, filed on October 12, 2018.” slip op. at 17

Biosig Instruments, Inc., 572 U.S. 898, 910 (2014); see 37 C.F.R. § 42.100(b) (changing the claim construction standard used to review a claim proposed in a motion to amend from the broadest reasonable construction to the “same construction standard that would be used to construe the claim in a civil action under 35 U.S.C.

Appendix A. Although this claim would have best been clarified by Patent Owner after seeking preliminary guidance on its Motion to Amend, upon review of the written description, claims, and figures of the ’740 patent, as well as Patent Owner’s clarification in its Reply to the Opposition, we agree with Patent Owner that one of ordinary skill in the art would have understood that the “in situ galvanically-active intermetallic precipitate” is merely a more complete description of the “in situ precipitate” mentioned earlier in the sentence.

    “The parties present compelling argument and evidence that one of ordinary skill in the art would include those with experience in ophthalmology, as well as in the research, manufacture, and design of medical optics or medical lasers. Pet. 26; PO Resp. 8–9. The evidence of record also demonstrates that few individuals actually had such comprehensive experience. Rather, teams of individuals with different expertise and various academic degrees (Ph.D.s, B.S.s, and M.D.s) would work together to design laser surgery systems intended to make incisions in the lens of the eye.

    “Having considered the parties’ positions and evidence of record, summarized above, we find that the evidence of record does not support a conclusion that it would have been simple, straightforward, or otherwise routine to convert Swinger’s manual HeNe aiming system and Swinger’s surgeon-identification-of-target-tissue step to a computer-controlled, OCTguided laser system. Even assuming that a person of ordinary skill in the art would have combined the teachings of Swinger and Baikoff to achieve a laser surgical system incorporating an OCT imaging system, that combination still would not have achieved the required “control system” of the claims and all of its programmed surgical functionality. Petitioner relies on the ability of a person of ordinary skill in the art to configure Swinger’s computer control unit with the missing functionality, thus necessitating an electronic conversion of the steps performed by a surgeon using Swinger’s direct visualization method using a HeNe aiming beam to manually identify a surgical treatment region for laser surgery. Ex. 1039, 34:52–57; Ex. 2088 ¶¶ 55–59, 66. That conversion, however, involves the incorporation of OCT imaging technology as the basis for a computer-controlled system to plan and then implement the planned cataract surgery, two technological leaps that the record fails to show were known or suggested. In particular, the evidence of record does not support a conclusion that OCT was a well-known system used routinely, if at all, in the identification of treatment regions in the lens or lens capsule for cataract surgery, and further does not support a conclusion that a computer-controlled system to plan and to implement a planned cataract surgery in the lens was commonplace or even considered before the invention. We recognize that Petitioner directs us to the testimony of Dr. Izatt who opines that a person of ordinary skill in the art would have found it obvious to, for example, use a controller to determine the claimed scanning pattern. Ex. 1001 ¶ 159; Pet. 32–33; Reply 3–5; see also Ex. 1123 ¶ 31 (“Once the anterior capsule is identified, it is a relatively simple process to determine the location to place the capsulotomy.”). Here, however, we agree with Patent Owner that the Petition and supporting testimony fails to provide the requisite reasoned analysis with sufficient evidence to support Petitioner’s position on obviousness. In particular, absent some evidentiary support beyond Dr. Izatt’s and Dr. Tipperman’s bare opinions that it would have been obvious to program a controller to bridge the gap between the functionality disclosed in Swinger and the required functionality of the challenged claims, we are unwilling to accept this line of reasoning.

    “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.

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.

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.

    “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.

    “In the Institution Decision, we agreed with Petitioner that the variable construction of the phrase “each independently” is the broadest reasonable interpretation in light of the specification, and construed the phrase to mean that “each variable R81, R82, R83, and R84 is independent from one instance to another throughout the polymer.” Institution Dec. 13–14. Based on that construction, we also determined in the Institution Decision that claim 2 encompasses the following genera: (1) “Genus A,” which includes a poly(ethylene glycol) chain transfer agent flanked by poly(ethylene carbonate) chains (Pet. 24); (2) “Genus B,” which includes a poly(propylene glycol) chain transfer agent flanked by poly(propylene carbonate) chains (id. at 25–26); (3) “Genus C,” which includes a poly(propylene glycol) chain transfer agent flanked by poly(ethylene carbonate) chains (id. at 26); and (4) “Genus D,” which includes a poly(ethylene glycol) chain transfer agent flanked by poly(propylene carbonate) chains (id. at 27). Institution Dec. 12–13. Neither party opposes adopting the variable construction of the phrase “each independently” and the determination that, under the variable construction, claim 2 encompasses Genus A, Genus B, Genus C, and Genus D. PO Resp. 2; Pet. Reply 1–3. We maintain the variable construction of the phrase “each independently” on the complete record.” slip op. at 11

    “j. Conclusion Regarding Obviousness Based on Hagiwara (Proposed Substitute Claims) We conclude that Petitioner has shown by a preponderance of the evidence that proposed substitute claims 20, 22, 23, and 26–29 are unpatentable as obvious in view of Hagiwara. We conclude that Petitioner has not shown by a preponderance of the evidence that proposed substitute claims 21, 24 and 25 are unpatentable as obvious in view of Hagiwara. 2. Remaining Grounds of Unpatentability Asserted by Petitioner (Proposed Substitute Claims) In view of our determination that Petitioner has shown by a preponderance of the evidence that proposed substitute claims 20, 22, 23, and 26–29 are unpatentable as obvious in view of Hagiwara, we do not reach Petitioner’s remaining grounds of unpatentability as to these claims. Regarding proposed substitute claims 24 and 25, Petitioner’s contentions regarding the Handbook, Wilson, and Say do not remedy the deficiencies in Petitioner’s contentions regarding Hagiwara, as discussed above. Accordingly, we conclude that a preponderance of the evidence does not show that proposed substitute claims 24 and 25 are unpatentable as obvious based on Hagiwara in view of the Handbook, Wilson, or Say.

    “As discussed above, we do not reach the Wilson-Based Grounds with respect to claims 1, 4–12, and 15–19 of the ’574 patent. As for claims 2, 3, 13, and 14, we determine that Petitioner has not shown unpatentability based on the Wilson-Based Grounds, even if Exhibit 1037 and the corresponding portions of Petitioner’s Reply (Paper 37) are not excluded, because Petitioner does not offer Exhibit 1037 to cure the deficiency we noted in Wilson. See Section II.F, supra. For this reason, we dismiss as moot Patent Owner’s motion.” slip op. at 72

    “sensor would not have been a motivation to combine Hagiwara’s embodiments” because Hagiwara’s catheter prevents damage to the sensor during insertion and because a sensor with a side sensor window creates a greater risk of damage and vascular injury and reduces exposure to blood, as compared with a sensor with an end sensor window. PO Resp. 20–25. We have considered Patent Owner’s arguments, but, for the reasons discussed above, we are persuaded that Petitioner has established a motivation to combine, notwithstanding the conflicting expert testimony regarding the disadvantages of a side sensor window versus an end sensor window. Neither of the expert opinions on this topic is supported by objective facts or data. Ex. 1006 ¶ 155;13 Ex. 2008 ¶¶ 54–57, 87–95; Ex. 2009, 92:8–97:12. For this reason, we give little or no weight to either side’s expert testimony 13 Dr. Vachon cites “WO 01/13102, Vadgama” (Ex. 1006 ¶ 155), however, this reference was not submitted as an exhibit in this proceeding. on this topic. 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.”); Rohm & Haas Co. v. Brotech Corp., 127 F.3d 1089, 1092 (Fed. Cir. 1997) (nothing in the Federal Rules of Evidence or Federal Circuit jurisprudence requires the fact finder to credit unsupported assertions of an expert witness). As discussed above, however, there is no disagreement that a side sensor window was a known alternative to an end sensor window. Ex. 1006 ¶¶ 73, 155; Tr. 43:22–44:3. That undisputed fact, together with Petitioner’s other evidence, is sufficient to establish a motivation to combine.” slip op. at 42

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “Level of Ordinary Skill in the Art For purposes of our Institution Decision, we accepted the definition of a person of ordinary skill in the art (“POSITA”) provided by Petitioner’s declarant, Dr. Vachon. Dec. 11 (citing Ex. 1006 ¶ 28). That definition is: a person having a bachelor’s degree or the equivalent training or experience in mechanical engineering, bioengineering, or related field and at least three years of experience relating to biosensor research and development, or a master’s degree or the equivalent training or experience in mechanical engineering, bioengineering, or related field, and at least one year of experience relating to biosensor research and development. Id. Patent (https://www.uspto.gov/sites/default/files/documents/guidance_on_motions_ to_amend_11_2017.pdf); Bosch Automotive Service Solutions, LLC v. Matal, 878 F.3d 1027 (Fed. Cir. 2017); Bosch Automotive Service Solutions, LLC v. Iancu, Order on Petition for Panel Rehearing, No. 2015-1928 (Fed. Cir. Mar. 15, 2018). Owner’s declarant accepts and applies this definition of a POSITA for purposes of his opinions. Ex. 2008 ¶ 30. Neither party’s declarant indicates that any proffered opinion would change depending on the level of ordinary skill in the art. Therefore, consistent with our Institution Decision, we adopt Dr. Vachon’s definition of a POSITA. Ex. 1006 ¶ 28. We also rely on the cited prior art references as reflecting the level of ordinary skill in the art at the time of the invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).” slip op. at 20
