To the extent that Kerry is seeking to disqualify Dr. Baldwin’s testimony in its entirety under Kyocera, we consider this to be a new argument that differs from Kerry’s initial argument that Dr. Baldwin’s testimony should be afforded little or no weight due to his lack of familiarity with the field of the ’304 patent. Because new arguments made for the first time in sur-reply are not permitted, we will only focus on Kerry’s initial challenge to the testimony of Dr. Baldwin. testimony, regardless of the subject of his particular opinions. It is clear that Dr. Baldwin has expertise in some areas of chemistry, while Dr. Milkowski’s experience is focused on other areas and emphasizes food chemistry. These differences in expertise may impact how we weigh the testimony of both witnesses, but that determination should be made in the context of a specific subject and based on the applicability of each witness’s background to the opinions. Therefore, we decline to adopt Kerry’s proposed approach of giving Dr. Baldwin’s testimony “little to no weight,” and instead will weigh the expertise of both witnesses in evaluating their testimony on specific areas of dispute, if necessary.” slip op. at 14

    “Upon review, we find that a person of ordinary skill in the art would have had reason to modify Voorde in the manner FFP suggests. Voorde explicitly discloses the advantages of heating the medium, and there is no disagreement that heating to 50–52°C would have resulted in at least some reduced microbial load, which is all that the claims require.13 Indeed, Voorde describes that as a result of heating to 50–52°C, its medium is “(partially) sterilized.” Ex. 1003, 7. Kerry’s argument that Voorde does not disclose starting with a “sterile medium” (PO Resp. 25) is unavailing; as discussed above, we do not interpret anything in claim 1 or the ’304 patent 13 At oral argument, Kerry raised for the first time a claim construction argument that “heat treating,” as recited in the claims, requires heating to a level in excess of what is required in Voorde, and a person of ordinary skill would have understood the term to refer to sterilization. Tr. 33:4–34:19, 55:3–9. We decline to address this late-arising argument fully, but note that we find that the ’304 patent does not support such a limited interpretation of the term “heat treating.” to require a sterile medium, and Kerry does not direct us to anything in the record that would persuade us otherwise.” slip op. at 18

    “Third, and most significantly, Petitioner points to Shimizu, a patent filed in 1999, as repeatedly referring to phosphor as a garnet-based fluorescent material. Reply 3 (citing Pet. 27; Ex. 1013, 10:16–13:50). We agree that Shimizu appears to use the two terms interchangeably. For example, Shimizu states that “[t]he phosphor is specifically garnet fluorescent material” and “the fluorescent material is preferably yttrium- aluminum-garnet fluorescent material (YAG phosphor) activated with cerium.” Ex. 1013, 10:17–30. Patent Owner does not dispute this reading of Shimizu, but argues instead that it is “impermissible to rely on an entirely different reference” in a Reply. See Sur-Reply 4–5 (citing Ariosa Diagnostics v. Verinata Health, Inc., 805 F.3d 1359, 1367 (Fed. Cir. 2015)). For the same reasons discussed above, we do not agree that Petitioner’s use of Shimizu is improper, but is instead a proper response to Patent Owner’s argument that a person of ordinary skill in the art would not have understood Yamazaki to disclose phosphor. Ariosa, relied upon by Patent Owner, confirms that the Board should consider an exhibit “for what it show[s] about the background knowledge that a skilled artisan would have possessed.” Ariosa, 805 F.3d at 1365 (“The Board’s language on its face supports Ariosa’s interpretation of what the Board meant—that the Board was declining to consider Exhibit 1010, even as evidence of the background understanding of skilled artisans as of January 2010, simply because the brochure had not been identified at the petition stage as one of the pieces of prior art defining a combination for obviousness. If that is what the Board meant, the Board erred. Art can legitimately serve to document the knowledge that skilled artisans would bring to bear in reading the prior art identified as producing obviousness.”). The Petition relies on Shimizu to show such background understanding. Pet. 27. Specifically, the Petition states that conventional LEDs “were made using the III-nitride material system, with semiconductor layers formed on sapphire substrates and combined with YAG phosphors to efficiently generate white light output.” Id. (citing Ex. 1013, 10:30–11:35). Thus, Shimizu is properly objective evidence supporting a finding that at least as early as 1999, a person of ordinary skill in the art would have used the terms “phosphor” and “fluorescent material” interchangeably. Moreover, Dr. Schubert’s textbook published in 2018 explicitly references Shimizu. Ex. 1039, 3-4. In this context, we find that Dr. Schubert’s textbook and testimony indicate that a person of ordinary skill in the art, at the relevant time, would have understood the terms to be interchangeable.” slip op. at 20

    “Based on the complete record, Petitioner establishes by a preponderance of the evidence that an ordinarily skilled artisan would have found the sapphire growth substrate obvious in light of Yamazaki’s disclosure. Petitioner cites Schubert to show an ordinarily skilled artisan’s knowledge about conventional blue LEDs as disclosed in Yamazaki, i.e., that “conventional blue LEDs were III-nitride-based LEDs that commonly included sapphire growth substrates.” See Pet. 71–72, 76–77; Ex. 1007 ¶ 27 (stating the disclosed light-emitting chip “is of a publicly known structure”); Ex. 1008, 166 (discussing “commonly used sapphire and SiC substrates”). We credit Dr. Dupuis’ testimony that is consistent with the prior art of record. Ex. 1035 ¶¶ 238, 248–251 (citing Ex. 1008, 166); Ex. 1007 ¶ 27; Ex. 1009, 1:10–17, 4:61–67; Ex. 1012, 243; Ex. 2013, 10:30–11:35. We are not persuaded otherwise by the deposition testimony of Dr. Dupuis pointed to by Patent Owner. PO Resp. 44 (citing Ex. 2016, 53:7– 12). This testimony confirms that Schubert does not explicitly discuss whether the sapphire growth substrate is included in an LED package. Id. (citing Ex. 2016, 53:7–12). However, Patent Owner does not dispute that sapphire growth substrates were commonly used (as confirmed by Schubert) or that a person of ordinary skill in the art would have reasonably expected a blue LED to include a sapphire growth substrate. See PO Resp. 42–43 (stating only that sapphire is one among several materials that could be used as a growth substrate); Sur-Reply 9–10 (same). Petitioner is not required to show that the proposed combination would have been preferred over other alternatives. Infineum USA L.P. v. Chevron Oronite Co.

Instead, the question is whether a person of ordinary skill in the art would have understood the disclosure of Yamazaki, in light of the disclosure in Schubert, to teach or suggest the sapphire growth substrate limitation.

    “In the Institution Decision, we determined that Petitioner’s definition was consistent with the disclosure of the ’351 patent and the scope and content of the asserted prior art to the extent that Petitioner’s definition requires familiarity with the design and operation of automated hematology analyzers available in the market. Dec. 8 (citing Ex. 1001, 1:45–61, 15:52– 58). We also determined that Petitioner’s proposal was more reasonable than Patent Owner’s with respect to the duration of a POSA’s practical experience, whether such practical experience is in addition to or possibly as experience could be merely using hardware and/or software for an analyzer, as opposed to developing such hardware and/or software. Id. at 8–9. Neither party contends that the differences in proposals affect the outcome of this proceeding, and we find that they do not. Nonetheless, on the full record now before us, we find that our identification of the level of ordinary skill in the art in the Institution Decision, modified to state that a higher level of experience can compensate for less technical education, is supported by the ’351 patent, the prior art of record, and the opinions of Mr. Roche and Dr. Robinson (which, as discussed above, recognize that additional work experience can compensate for technical education). Thus, we find that a POSA would have had at least a Bachelor’s or Master’s degree in biologic science, biomedical engineering, and/or electrical engineering or a related field and at least five years of experience in developing hardware and/or software for hematology analyzers, and would have been familiar with the design and operation of hematology analyzers available in the market.

    “Based on our review of the record, we determine that Petitioner has established that a POSA would have had reason to combine the teachings of Nagai and Jagtiani to achieve the claimed subject matter. Nagai describes an electrical detector (RBC/PLT detection unit 42) that “is capable of measuring the number of red blood cells and platelets by a sheath flow-DC detection method.” Ex. 1044, 6:58–63, Fig. 5. Nagai also describes WBC detection unit 41 that produces a DIFF scattergram that, in the body fluid measuring mode, is analyzed in order to classify the white blood cells into two subclasses, namely, mono-nucleated cells and poly-nucleated cells. Id. at 5:56–58, 12:27–36. Nagai teaches that WBC detection unit 41 is “configured as an optical detection unit” that performs white blood cell classification in the body fluid measurement mode using a combination of electrical resistance and absorbed light. Id. at 5:56–58, 15:52–16:6. Jagtiani teaches a channel sensor that can detect impedance to differentiate between different types of cells in a biological sample, including differentiating between red blood cells, white blood cells, and platelets. Ex. 1045 ¶¶ 21, 25; see also id. ¶ 187 (“The channel sensor is based on impedance sensing using the Coulter principle.”). Jagtiani teaches the sensor can be configured to differentiate between and count the number of eosinophils, basophils, neutrophils, monocytes, and lymphocytes in the biological sample. Id. ¶ 25; see also id. ¶ 121 (“In some embodiments, the cell count can include a white blood differential, and can include a count of basophils, a count of eosinophils, a count of lymphocytes, a count of neutrophils, and/or a count of monocytes.”). Jagtiani further teaches that “[s]uch biological samples can include, for example, blood, serum, saliva, sweat, tears, urine, or any other biological sample or derivative suspended in a fluid.” Id. ¶ 119. In light of these teachings in Nagai and Jagtiani, we credit Mr. Roche’s testimony that Jagtiani demonstrates a known technique of detecting poly-nucleated and mono-nucleated white blood cells using an electrical detector. A POSA at the time of the invention would have been led to modify Nagai with the teaching of Jagtiani in the manner claimed to allow the body fluid measurement of Nagai to differentiate poly-nucleated and mono-nucleated blood cells (instead of measuring red blood cells alone). Such a motivation is found, for example, in Petitioner’s DxH system, which discloses use of an electrical detector in both a blood measuring mode and a fluid measuring mode. Ex. 1042 ¶¶ 30, 31. In the DxH system, use of an electrical detector in both the blood measuring mode and body fluid measuring mode allows identification of total number of cells in measured body fluid.” slip op. at 29

See PO Resp.; PO Sur-Reply. Patent Owner’s counsel similarly was unable to identify any such authority at the hearing. Tr. 42:9–15. Further, Mr. Klass’ testimony was not that he is not a person of ordinary skill in the art, but rather that his opinions set forth in his earlier declaration would not be different under the level of ordinary skill as defined by Mr. May. Ex. 1028 ¶¶ 4–5. On this record, we find Mr. Klass’ testimony well-supported as it pertains to relevant issues and see no reason to summarily disregard it. See Exs. 1002, 1028. Complete overlap between a witness’ technical qualifications in the field of the invention is not necessary for the witness’ testimony to be admissible. See SEB S.A. v. Montgomery Ward & Co., Inc., 594 F.3d 1360, 1372–73 (Fed.

    “On this record, we determine that a person of ordinary skill in the relevant art would have included those with a bachelor’s degree in mechanical or paper engineering with at least a year’s experience relating to producing cushioning materials, dunnage pads, and other protective packaging. As admitted by Patent Owner, production of such materials using kraft paper stock was known. PO Resp. 14. As to the use of double-sided adhesive, we do not agree with Patent Owner that it was unknown to the person of ordinary skill in the art because using double-sided tape to join rolls of sheet stock was known in the wider field of paper processing and we find that field reasonably includes producing paper cushioning products, and that such related knowledge reasonably would also have been within the knowledge of a skilled artisan in the “cushioning conversion machine” field as the same or similar paper cushioning products are produced. Moreover, regardless of whether double-sided tape was used in what Patent Owner contends is the “cushioning conversion machine” field, Mr. May’s testimony is limited to it not being used in that field, not that double-sided tape itself was not known to one of ordinary skill in the art in the field. Ex. 2001 ¶¶ 53–57. It reasonably follows that a person having knowledge of double-sided tape would also have knowledge of joining together sheets of paper or other stock using double-sided tape. Further, to the extent that Patent Owner and Mr. May rely on “cushioning conversion machines” differing from paper processing machines that produce paper cushioning products, on this record, there is insufficient evidence of a meaningful difference in their complexity, size, or operation. For example, Patent Owner relies heavily on the paper processing machines including machinery to allow splicing on the fly, but the prior art also teaches that non-continuous roll-to-roll splicing can be used. See Ex. 1010, 1:13–16 (disclosing that a splicing tape system “is applicable both to systems in which the splice is made on the fly and to systems in which the splice is made while the running web is stationary”); Ex.1017, 1:15–19 (disclosing that “[t]he splicing operation can be performed in a static or a dynamic mode.”). As to size, similarly, Patent Owner relies on the machinery for paper making or producing corrugated cardboard being larger than “cushioning conversion machines,” but there is no clear distinction between the two as to size, as discussed below. Also, there is no evidence that paper processing machines forming paper cushioning products from paper itself do not do so in the same general manner as the ’096 patent. Accordingly, finding no meaningful distinction to “cushioning conversion machines,” we discern no meaningful difference in the knowledge of the skilled artisan as it relates to the challenged claims. Moreover, to the extent that there would be a narrower “cushioning conversion machine” field that did not include the use of double-sided tape, as Patent Owner contends, there would be no difference in the outcome of this case. As to obviousness, the scope of analogous prior art is not limited to the field of inventor’s endeavor, but also includes references that are “still reasonably pertinent to the particular problem with which the inventor is involved.” See In re Bigio, 381 F.3d 1320, 1325 (Fed.

    “On this record, we determine that the preamble’s recitation of “sheet stock material for use in a cushioning conversion machine” is a statement of intended use and does not constitute a limitation. In doing so, we must construe the meaning of the term “cushioning conversion machine.” In construing “cushioning conversion machine,” we note there is no guidance elsewhere in the remaining claim language as to its meaning, including in other claims, and so turn to the specification of the ’096 patent. See Phillips, 415 F.3d at 1312–13, 1315. The ’096 patent states that “[c]ushioning conversion machines convert [paper] sheet stock material . . . into a cushioning dunnage product.” Ex. 1001, 1:23–25 (Background). The ’096 patent also identifies its “invention [as] relat[ing] to machines for converting sheet stock material into a dunnage product.” Id. at 1:15–16 (Field of the Invention).

    “On this record, Mr. May’s testimony of what “cushioning conversion machine” means in the field of paper dunnage machines fails to bear the weight required to limit the term as Patent Owner proposes. The ’096 patent identifies “cushioning conversion machines” to be machines that “convert sheet stock material . . . into a cushioning dunnage product.” Ex. 1001, 1:23–25 (Background). This is in effect the plain and ordinary meaning of the words themselves identifying a machine that converts feedstock into cushioning. Further, we find it consistent with the ’096 patent as a whole. Mr. May’s contrary testimony, as discussed above, lacks sufficient evidentiary basis to support Patent Owner’s contended construction over the plain and ordinary meaning. In effect, the basis for Mr. May’s testimony is limited to a showing that the meaning of the term encompasses a machine such as shown in the ’096 patent’s Figure 1 and 2. Mr. May’s testimony as to the PadPak machine being a “popular cushioning conversion machine[]” only goes to establishing that “cushioning conversion machine” encompasses similar machines, not that the term would be understood to be limited to the PadPak machine. Ex. 2001 ¶¶ 65–66. As to “cushioning conversion machines” being stop/start machines, the ’096 patent’s states that “the conversion machine 10 may be controlled by a controller” (emphasis 7 Elsewhere Patent Owner cites a number of its patents for using the term “cushioning conversion machine,” but this only supports that Patent Owner uses the term. See PO Resp. 27. added), not that it must be. Ex. 1001, 6:42–43. As to size, as discussed above, the ’096 patent provides no limitation as to the size of the apparatus or the sheet stock material. Petitioner highlights that another of Patent Owner’s patents, U.S. Patent No. 6,200,251 B1 (Ex. 1026, “the ’251 patent”), discloses “that in a ‘preferred cushioning conversion machine, the stock supply assembly is adapted to supply stock material which is between 25 to 35 inches wide’” (emphasis added). Pet. Reply 14 (citing Ex. 1026, 2:56–59). Petitioner also highlights that the ’251 patent was filed before the ’096 patent’s priority date and names the ’096 patent’s inventor among its inventors.

Such disclosure of a preferred embodiment in this circumstance is reasonable evidence that a skilled artisan would understand that a “cushioning conversion machine” included those “adapted to supply stock material . . . between 25 and 35 inches wide,” but not that such machines were limited to using such widths. The relevance of this is that the sheet stock material used is not manifestly distinct from the sheet stock material used for corrugators, ranging from 35 to 110 inches in width, where Patent Owner contends corrugators are distinct from “cushioning conversion machines.” See Ex. 2003, 95:22–96:6 (Mr. Klass testifying that the “width of commercial corrugators could be anywhere from 35 to 110 inches.”); PO Resp. 33–34 (relying on Mr. Klass’ testimony). Similarly, there is no persuasive evidence of a clear distinction in weight. Patent Owner and Mr. May rely on Mr. Klass’ testimony as to the weight of paper rolls for corrugators, focusing solely on testimony as to the weight of large rolls and ignoring that the testimony also set forth that “[s]ome corrugators use smaller rolls.” PO Resp. 34; Ex. 2001 ¶¶ 77–79; Pet.

    “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.

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. (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

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

    “Both parties appear to be in general agreement regarding the level of skill, and neither party contends that any differences between their proposals would have any effect on our analysis of Petitioner’s challenges. Although we encouraged the parties (Institution Dec. 7–8) to address any material differences between the two proposals in post-institution briefing, neither party addressed the issue. See generally PO Resp.; Reply; Sur-Reply. We, therefore, adopt a level of ordinary skill that encompasses a person with a degree in mechanical or electrical engineering or a related field and the equivalent of several years of experience in designing semiconductor LED packages.” slip op. at 8

    “As detailed below, we determine that Patent Owner has not shown that the term “lead frame,” as recited by the challenged claims, requires that any component lead provide support to the LED chip. Instead, we maintain our construction from the Institution Decision that “lead frame” in this context means a support structure for providing an interface to a semiconductor die, where the lead frame structure, as a whole, provides the support to the semiconductor die.” slip op. at 10

    “We agree that Okamoto shows the claimed lead frame, as a whole, providing support to the LED chip as required by claims 1 and 13. As shown in Okamoto’s Figure 1, reproduced above, “lead frame 8 is attached to the wiring pattern 6 drawn around an end of the glass substrate 2 with a solder material 9.” Ex. 1008 ¶ 29. According to Patent Owner, Okamoto’s transparent plate “supports the lead frame,” (PO Resp. 10) and as agreed upon by the parties, the claimed lead frame includes the transparent plate. Okamoto also discloses that the LED chip is on transparent glass substrate 2. Id. ¶ 27 (stating that LED elements “are disposed in a row on a front face of a light-transmissive glass substrate 2.”). Based on this disclosure, we find Okamoto teaches or suggests a lead frame that includes a transparent plate supporting an LED chip.” slip op. at 23

    “construction requiring at least one lead to provide structural support to the LED chip. First, Patent Owner contends that the plain meaning of the term “lead frame” requires that the leads must form “the structural frame supporting the LED chip.” Sur-Reply 4. According to Patent Owner, “[o]n its face, the meaning is clear” that “‘lead frame’ is a frame formed by leads.” Id. We do not find this conclusory statement helpful in determining whether the leads in a lead frame are required to provide structural support to the LED chip. Patent Owner does not identify any evidence, intrinsic or extrinsic, that the plain meaning of the term “lead frame” requires that any leads provide direct or indirect support to the LED chip. In fact, Patent Owner refers to several dictionary definitions of the term “lead frame,” none of which makes any reference to support. PO Resp. 5 (citing Ex. 1023, 4 (“Lead Frame. The metallic portion of a component package that is used to interconnect with semiconductor die by wire bonding and to provide output terminal leads.”); Ex. 1024, 4 (“lead frame— . . . 2. The metal part of a solid-state device package that achieves electrical connection between the die and other parts of the system of which the IC is a component. . . .); Ex. 1026, 3 (“lead frame the metallic portion of the device package that makes electrical connections from the die to other circuitry.”).” slip op. at 11

    “The fundamental error in Petitioner’s argument on this point, however, is that the claims at issue in this proceeding do not require “a lead frame including a transparent plate,” but instead “a lead frame having a transparent plate therein.” Petitioner must do more than show that Okamoto discloses that “the transparent plate is part of the lead frame,” as argued in the Petition. And, as we pointed out in our Institution Decision, Petitioner concedes that “Okamoto’s lead frame sits on its transparent plate, rather than the transparent plate being in the lead frame.” Institution Dec. 17 (citing Pet. 39; Ex. 1008 ¶¶ 34, 36). During the trial, Petitioner did not engage with this issue or provide any reason for us to diverge from our prior conclusion that, because “the plain language of the claims requires that the lead frame have a transparent plate ‘therein’ . . . [b]y Petitioner’s own admission . . . Okamoto does not anticipate.” Id. In other words, because Petitioner concedes that Okamoto’s transparent plate is not in its lead frame, it cannot meet the requirement of claims 1 and 14 that the lead frame have a transparent plate therein. For this reason, we maintain our prior determination that Okamoto does not disclose a lead frame having a transparent plate therein, and as a result, Petitioner has not shown by a preponderance of the evidence that claims 1 and 14 are anticipated.” slip op. at 23

    “Patent Owner also asserts that “Petitioner fails to explain how its proposed modification of wrapping the wiring pattern 6 around the ends of the substrate results in a lower-profile.” PO Resp. 17. According to Patent Owner, “Okamoto already provides the alleged lower-profile benefits of Shimizu, as seen by comparing figure 2 of each reference.” Id. at 18. But Dr. Dupuis supports Petitioner’s contention by stating that a person of ordinary skill in the art would know to use a “chip-type” package instead of a “lead-type” package in applications where a lower profile is needed. Ex. 1003 ¶¶ 129–134 (citing Ex. 1017, 8:31–67; Ex. 1016, Fig. 1, 33–35; Ex. 1022, Figs. 1–3, 6–8, 13, ¶¶ 2–14). Also, Okamoto states that Figure 2 is “a planar view of the light source device of” Figure 1. Ex. 1008 ¶ 43. And Figure 1 of Okamoto, reproduced above, clearly shows protruding lead frame 8. Id. at Fig. 1, ¶ 29. Figure 2 of Okamoto, however, does not show lead frame 8. See id. at Fig. 2. Thus, we do not agree with Patent Owner that Figure 2 of Okamoto shows a package with a lower profile. Instead, the record supports Petitioner’s position that the modified device created using the disclosures of Okamoto and Shimizu has a lower profile (i.e., leads wrapped around substrate 2 as opposed to protruding as shown by Okamoto Figures 1 and 8). See Pet. 42–43; Ex. 1003 ¶¶ 138–142. Patent Owner argues that “Petitioner ignores Dr. Schubert’s explanation that Shimizu was directed towards general illumination, while Okamoto is directed towards a signaling light source” so a person of ordinary skill would not combine the two references. Sur-Reply 16 (citing Ex. 1044, 93:15–96:13). Because we do not see this argument in Patent Owner’s Response, nor do we see anything in Dr. Schubert’s declaration to support such an argument, we do not agree that Petitioner improperly failed to respond to an argument. See PO Resp. 12–21; Ex. 2008 ¶¶ 112–120. Moreover, we find that both Shimizu and Okamoto disclose methods of creating white light using an LED and, therefore, the evidence supports a finding that both references are relevant to a consideration of obviousness. In re Oetiker, 977 F.2d 1443, 1447 (Fed. Cir. 1992) (“In order to rely on a reference as a basis for rejection of the applicant’s invention, the reference must either be in the field of the applicant’s endeavor or, if not, then be reasonably pertinent to the particular problem with which the inventor was concerned.”). In sum, on the complete record, we find that the combination of Okamoto and Shimizu teaches each limitation of claims 1 and 14, and we find that a skilled artisan would have had reasons, with rational underpinning, to combine Okamoto and Shimizu.” slip op. at 29

    “Upon further review, and in light of the arguments in Petitioner’s Reply (Reply 21–24), we conclude that our preliminary determination in the Institution Decision was in error, to the extent that we agreed with Patent Owner’s arguments that claims 13 and 26 require “all layers” of the LED to be transparent. The claims recite “a plurality of III-nitride layers, including an active region that emits light, wherein all of the layers except for the active region are transparent.” Ex. 1001, 21:46–52. The second half of this phrase, which contains the transparency requirement, recites “the layers,” meaning that it relies on an earlier recitation in the claim for antecedent basis of “layers.” This basis is found in the recitation of “a plurality of III-nitride layers.” In other words, the proper interpretation of “all of the layers” in claims 13 and 26 is that the term refers back to the III-nitride layers, not all of the layers of the LED as a whole (such as, for example, a mirror). And the parties agree that the mirror of a conventional LED is not a III-nitride layer. Tr. 18:15–18; 45:4–13. As a result, our preliminary determination that the non-transparent mirror of the APA LEDs prevented a finding of obviousness was incorrect. We agree with Petitioner that the ’916 patent admits that LEDs having transparent III-nitride layers were conventional in the art, and that these are “all of the layers except for the active region” as required in claims 13 and 26. Notably, during the trial Patent Owner did not attempt to defend against Petitioner’s ground for the same reason it raised in the Preliminary Response; instead, Patent Owner now argues that because of the mirror on conventional LEDs, these devices would not meet the claim limitation that “light is extracted effectively through all the layers.” PO Resp. 21. But this reflects a misunderstanding of Petitioner’s ground of unpatentability, which does not rely on the APA for this limitation. Petitioner’s ground is based on the argument that, while Okamoto discloses an LED without a mirror, it does not “specifically describe the layers of its blue LEDs, other than to say that it is a GaN-based LED.” Pet. 61. Petitioner turns to the APA for this missing information regarding the layers that were conventionally used in LEDs; but notably, the Petition does not rely on the APA’s mirror. Id. All Petitioner concludes from the APA is that a person of skill in the art “would reasonably expect the GaN-based LEDs of Okamoto to include multiple layers, which layers would at least include an active layer sandwiched between a p-side layer and an n-side layer.” Id. (citing Ex. 1003 ¶¶ 203– 205; Ex. 1001, 10:20–31). Patent Owner’s argument that the application of the APA’s layers to Okamoto would have brought along the mirror of the APA LED’s is therefore misguided and unpersuasive. In sum, we agree that a person of ordinary skill in the art would have looked to conventional LEDs, such as those admitted to be prior art in the ’916 patent, when determining the layers of Okamoto’s LED. And according to the ’916 patent, these conventional III-nitride layers would have been understood to be transparent to an emission wavelength. As a result, we conclude that claims 13 and 26 would have been obvious over the combined disclosures of Okamoto and Shimizu in light of the APA.” slip op. at 35
