Conroy refers to Conroy Protocol (Ex. 1004), stating that “[t]he protocol, including the statistical analysis plan, is available with the full text of this article at NEMJ.org.” Ex. 1003, 3. When questioned whether he has “any reason to believe that the protocol would not have been provided on NEJM.org with this text when it was published,” Dr. Oberstein testified that “if they say they provided it, then I think they probably provided it.” Ex. 1210, 165:20–166:2. 17 Alternatively, to the extent necessary, under the circumstances of this case, we waive the requirement of § 42.63(b).

The person of ordinary skill in the art has spent several years studying the structure and function of organic optoelectronic components, in particular OLEDs, and has detailed knowledge of the chemical structure of light-emitting organic layers and the transport of charge carriers to these layers.

    “Based on the information presented, we find Petitioner has the better position. Patent Owner admits that joint vaporization means “two materials vaporize together.” Reply 21 (quoting Resp. 54). As Petitioner argues, “This is what Ma discloses.” Id. We agree with Petitioner that Ma describes a “two-component” electron transport layer having a “thickness with one value.” Id.; see Ex. 1007, 811 (reporting a “co-deposited” application of “BPhen:LiQ” that is “50 nm thick”). Ma’s disclosure, thereby, strongly “indicates that the two components were vaporized together––as opposed to creating a ‘macroscopically homogenous form’” prepared by sequentially vaporizing the individual components as Patent Owner “hypothesizes.” Reply 21 (citing Ex. 1020 ¶¶ 42–44; Ex. 2041 ¶¶ 155–157); see Resp. 54– 55; see also Ex. 1007, 811 (Ma’s description of its device fabrication, appearing in the third paragraph of the experiments section). Petitioner further advances evidence that “[p]reparing a layer that is ‘macroscopically homogeneous’ but potentially microscopically heterogeneous,” as Patent Owner postulates, “would introduce excessive variability and render the data noncomparable and unreliable, thus undermining the experiment’s purpose.” Reply 21 (citing Ex. 1020 ¶ 44); see Resp. 54–55. Patent Owner presents no counterargument or evidence that is persuasive to undercut Petitioner’s reasoning or evidence on that point. See Sur-reply 19–22. Petitioner also argues that an ordinarily skilled artisan would have recognized “that vaporizing materials together would best achieve Ma’s objective of assessing the current density using different Liq doping percentages.” Reply 22 (citing Ex. 1007, 811; Ex. 1020 ¶ 51). Here again, Petitioner’s evidence on point stands uncontested. See Sur-reply 19–22 (declining to contest that point). On this record, therefore, we agree with Petitioner that, as to the relevant disclosure in Ma, “the most natural interpretation of ‘co-deposition’ for forming a layer, particularly when there is nothing to indicate that the materials” are “vaporized sequentially,” is that the materials are co-deposited by joint vaporization. Reply 22 (citing Ex. 1020 ¶ 46–51). We further agree that, “[u]nder a preponderance standard, Ma’s disclosures are sufficient to render joint vaporization at least obvious.” Id. For the above reasons, we determine that Petitioner demonstrates by a preponderance of the evidence that Ma discloses joint vaporization as required by the challenged claims.” slip op. at 15

Petitioner’s witness (Mr. Cook) qualifies as a POSITA under this definition, and, therefore, is qualified to opine from the perspective of a POSITA on technical matters included within the areas of expertise prescribed by the definition. As indicated above, Petitioner’s definition of a POSITA does not require education in the field of optics and professional experience designing or analyzing optical apparatus, unlike Patent Owner’s definition. We are aware, however, that Patent Owner’s witness (Dr. Klopp) has more extensive experience with optical systems and methods than Petitioner’s witness (Mr. Cook).

Petitioner’s assertions that this would be the case consist solely of conclusory statements, supported only by citations to Mr. Cook’s declaration.

Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). Furthermore, Mr. Cook’s opinion conflicts with that of Patent Owner’s witness, Dr. Klopp, who opines that a “POSITA would understand from Tseng’s third embodiment that light from the LED would bypass the annular protrusion 383 of outer cliff 381, while transmitting downwardly toward the output face 313.” Compare Ex. 1003 ¶¶ 174–175, 190–194, with Ex. 2003 ¶¶ 101–102, 105. As discussed above, Mr. Cook is qualified to opine from the perspective of a POSITA on technical matters included within the expertise of a person meeting Petitioner’s definition of a POSITA, which do not include optics and optical apparatus. We, therefore, credit Dr. Klopp’s opinion over that of Mr. Cook on this particular factual issue of how it is directly related to optical systems and methods about which Mr. Cook possesses limited relevant experience.

Cir. 2019) (explaining that, generally, a novel product that meets the criteria of patentability is not limited to the process by which it was made, however, process steps can be treated as part of a product claim if the patentee has made clear that the process steps are an essential part of the claimed invention). Here, the portions of the Specification relied on by Petitioner (Ex. 1001, 2:10–20, 4:53–64) disclose a process for manufacturing but do not make clear that the process is an essential part of the claimed invention. We also disagree with Petitioner’s assessment of the prosecution history, i.e., that the claims were amended to distinguish the claimed rounded corners from Pfirsch’s rounded corners, which, presumably, are formed as an incidental result of lithography. On the contrary, the Examiner found (and Patent Owner acknowledged) that Pfirsch has rounded corners. Ex. 1002, 276, 295, 302. As Patent Owner correctly points out, the claims were amended during prosecution to include a “circular” contact to distinguish over Pfirsch’s square contact. See id. Petitioner does not otherwise point to evidence that Patent Owner clearly and unmistakably limited the claim scope to rounded corners formed by a particular process.” slip op. at 12

    “is ‘known’ is not sufficient for a motivation to combine.” PO Resp. 47. However, the motivation-to-combine analysis is a flexible one, and the “known-technique” rationale is adequate to show a motivation to combine. For example, “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 his or her skill.” KSR, 550 U.S. at 417; see also Intel Corp. v.

Cir. 2021) (“If there’s a known technique to address a known problem using ‘prior art elements according to their established functions,’ then there is a motivation to combine.”). Here, as discussed above, the record shows that top view rounding was a known technique to eliminate corners, and that corners were a known problem (e.g., corners tend to reach undesirable higher peak electric field leading to premature breakdown voltage). See, e.g., Ex. 1003 ¶¶ 37, 39, 42– 44, 55–57, 122, 133, 135–141; Ex. 1005, 7:57–8:4; Ex. 1006, 1:18–21, 2:19–39, 5:3–17, Figs. 6A–8B; Ex. 1011, 1:29–41; Ex. 1012; PO Resp. 13, 46 (citing Ex. 1011, 1:34–40); Ex. 2021 ¶ 87.

    “We agree that Kobayashi’ s Figure 5A solely cannot be relied upon as disclosing the claimed diameter. See Hockerson-Halbertstadt, Inc. v. Avia Group Int'l, 222 F.3d 951, 956 (Fed. Cir. 2000) (patent drawings not designated as being drawn to scale cannot be relied upon to define precise proportions of elements if the specification is completely silent on the issue). However, we do not agree that Petitioner failed to show Kobayashi suggests the recited diameter. We disagree with Patent Owner’s assertion that Dr. Liu’s “vague, purported ‘design considerations’” are “unsupported.” PO Resp. 43. Although Kobayashi is silent on the width/diameter of the trench contact in Figure 5A, Kobayashi discloses trenched gates having dimensions below 0.5 μm, which demonstrates that it was known in the art, and required no more than an exercise of ordinary skill in the art, to create trenched features of widths well below 1 μm. Kobayashi also discloses that the width of each trench, and the distance between the adjacent trenches (which includes the trench contact), must be selected to optimum sizes . . . [and] these sizes . . . have some degrees of freedom.” Ex. 1005, 7:42–48. This demonstrates a POSITA would seek to optimize trench contact width or diameter. Dr. Liu’s testimony regarding design considerations suggests the desirability of a reduced diameter trench contact, e.g., to minimize the width of the trench contact for purposes of easier filling, to minimize the total width of the unit cell, and to minimize manufacturing time by reducing etch back time. See Ex. 1003 ¶¶ 111–114. As Patent Owner acknowledges, “there is always a motivation to speed up the fabrication process or shrink feature sizes of semiconductors.” PO Resp. 43 (citing 2021 ¶ 131). However, contrary to Patent Owner’s arguments, these are not generic motivations “untethered” from Kobayashi. Id. Indeed, Kobayashi directly addresses the fabrication process (including new techniques to obtain trench widths under 0.5 μm) and the need to optimize the size of trench gates and the space in between (which includes the trench contact). Ex. 1005, 7:43–54, 7:19–9:53. Patent Owner also argues that Petitioner presents no evidence that modifying Kobayashi to have a diameter smaller than 1 μm is predictable. PO Resp. 44. We disagree. As discussed above, Petitioner points to Kobayashi’s teachings that the sizes are to be optimized and that the trench gate width is smaller than 0.5 μm, which suggests making other trench features of that width was within ordinary skill. Ex. 1003 ¶ 112. Furthermore, Kobayashi’s silence as to the dimensions of the trench contact suggests that the trench contact diameter dimension is likely in the ballpark of the other explicitly disclosed trenched feature dimensions and is a matter of routine optimization. In addition, Patent Owner advances no persuasive evidence that the claimed diameter produces unexpected results or is otherwise critical. Patent Owner also argues that reducing trench contact diameter has downsides (i.e., reduced ease of filling for metal plugs and reduced current carrying capacity) not addressed by Petitioner; however, Petitioner is not required to address those tradeoffs in its Petition, and we do not see how those tradeoffs would prevent the proposed combination. PO Resp. 44; see Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006) (“a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine.”); Winner Int'l Royalty Corp. v.

Instead, the benefits, both lost and gained, should be weighed against one another.”). Here, Dr. Liu listed numerous benefits of having a reduced diameter, which weigh against the potential downsides raised by Patent Owner. Ex. 1003 ¶¶ 111–114.

    “It is of the utmost importance that petitioners in the IPR proceedings adhere to the requirement that the initial petition identify ‘with particularity’ the ‘evidence that supports the grounds for the challenge to each claim.’” Intelligent Bio-Sys., Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1369 (Fed. Cir. 2016) (quoting 35 U.S.C. § 312(a)(3)). Here, however, not until its Reply does Petitioner belatedly suggest that Ferrante’s disclosure of bone screws with self-tapping ends equally meets the limitation of claim 10 (with respect to the first member) as with claim 11 (with respect to the second member), and that both claims are obvious in light of “evidence” from Ferrante “that it was well known to equip bone screws with self-tapping ends.” Reply 26–27. We do not discern these arguments in the Petition, and consider them waived. See Netflix, Inc. v. DivX, LLC, 84 F.4th 1371,1377 (Fed. Cir. 2023) (“While the Board should not take an overly mechanistic view of a petition and decline to address an argument because the petitioner did not present it with ideal vigor and clarity, the Board should also not have to decode a petition to locate additional arguments beyond the ones clearly made.”). In sum, Petitioner’s error in failing to first address limitations of claim 10 in the Petition specific to the Cognet/Ferrante combination indicates a failure to meet the particularity requirements for what must be in the petition and cannot be left to be filled in on reply. See 35 U.S.C. § 312(a)(3); 37 C.F.R. §§ 42.22(a)(2) (requiring, among other things, “a detailed explanation of the significance of the evidence”), 42.104(b)(4)–(5) (requiring that petition “specify where each element of the claim is found in the prior art patents or printed publication relied upon” and, regarding submitted evidence, state “the relevance of the evidence to the challenge raised, including identifying specific portions of the evidence that support the challenge”).

    “We also find persuasive Mr. Dominguez’s explanation that one of ordinary skill in the art would have understood “bore” as including stepped diameter holes, sometimes described as a bore having a counterbore. See generally Ex. 1018 ¶¶ 4–29; Reply 3–10. Three of Mr. Dominguez’s illustrative examples are reproduced in the annotated figures below. The above figures show Mr. Dominguez’s annotated illustrations from the Jackson (Ex. 1019, Fig. 3), Brånemark (Ex. 1021, Fig. 4), and Ray (Ex. 1025, Fig. 1) references as discussed at paragraphs 10, 12, and 13, respectively, of Mr. Dominguez’s Second Declaration. With reference to the above figures, Mr. Dominguez testifies that “Jackson describes a bone repair set screw in which ‘[t]he bore 27 comprises a first bore section 31, a second bore section 32,’ etc. delineated by shoulders 41, 42, etc. (Ex. 1019, 5:24– 43)” (Ex. 1018 ¶ 10); “Brånemark describes an osseous implantation device having body 1ʺ with first and second holding portions 21ʺ, 31ʺ and ‘an inner through bore with a first portion 4ʺ in the first holding portion and a second portion 5ʺ in the second holding portion.’” Ex. 1021, 4:44–46” (id. ¶ 12); and Ray discloses surgical calipers including “handle 12 having ‘stepped cylindrical bore 14,’” wherein “[c]ollar 20 of a shaft inserted in the bore ‘rests against a step of the bore 14’ (2:14–15)” (id. ¶ 13). Patent Owner responds that Mr. Dominguez’s examples “that allegedly show a single bore encompassing two or more stepped-diameter holes or a counterbore . . . . are specific to these references and divorced from the disclosures of the ’166 patent.” Sur-Reply 7. Insofar as the ’166 patent makes no mention of the term “bore” outside the claims, and Mr. Dominguez’s examples are all taken from the field of orthopedic surgery, we do not find this argument persuasive. Patent Owner further appears to contend that exemplary references to a “cylindrical stepped down bore” or a “stepped cylindrical bore” are too specific to be within the scope of the term “bore.” Sur-Reply 7–8. As these terms merely describe species within a larger genus, and Patent Owner presents no cogent reason to exclude them, we do not find this argument availing. Relatedly, we are also not persuaded by Patent Owner’s argument that “the prior art treats a ‘bore’ as an element that is distinct from a ‘counterbore.’” Id. at 8. Rather, we credit Mr. Dominguez’s testimony that “[a] counterbore is not a structure unto itself, a counterbore is part of a larger structure” as exemplified by numerous examples including Laps (Ex. 1028 ¶ 33 (sensor assembly wherein “bore 16 includes a counterbore 18”)); Martinez (Ex. 1029, 3:61 (surgical cutting instrument wherein “bore 56 has a counterbore 64”)); Zang (Ex. 1030, 2:49 (bone anchor having a “bore [that] includes a counterbore”)); Ledet (Ex. 1022, 29:3–5 (vertebral fixation plate having “through holes . . . . countersunk, or counterbored to accommodate the head of a bone screw”)); Seo (Ex. 1031, 3:45 (chair leg employing “counterbored bore 23”)); and Exner (Ex. 1032, 2:16 (extrusion press including “counterbored axial bore 6”)). Ex. 1018 ¶¶ 17–23. That a reference may refer to a figure as showing “bore 103” with “counterbore 105 . . . formed on one end” does not indicate that they are distinct structures as Patent Owner contends, but merely that the focus of each term is directed to the entire bore or to a particular aspect of the bore, i.e., its counterbore.

    “one of ordinary skill in the art would understand that “bore,” as used in the context of claims 1 and 12, encompasses a multi-diameter passage, and in particular, one having stepped longitudinal cross sections such as that shown in Cognet’s Figure 1. See generally DI 11–13. For the reasons that follow, we conclude that one of ordinary skill in the art would have understood “bore” as such. Relying on the testimony of Mr. Dominguez, Petitioner initially proposed a construction of “bore” as “a usually cylindrical hole made by or as if by the turning or twisting movement of a tool.” Pet. 16 (citing Ex. 1002 ¶ 58). Petitioner’s proposal relied on Mr. Dominguez’s testimony that “[a] bore is a cylindrical hole made by the spinning rotation of a twist drill cutting tool. It is typically made by removing material from a solid or hollow object, similar to a tunnel or orifice.” Ex. 1002 ¶ 58. Pointing to its annotation of Cognet’s Figure 1, above, Patent Owner argued that that the term “bore” excludes a tunnel made by “two adjacent bores.” See Prelim. Resp. 21–25. In view of the then-available evidence, we provisionally construed “bore” as a hole or passage made by or as if by the turning or twisting movement of a tool such that its interior walls have cylindrical lateral cross-sections, and which do not exclude holes or passages having tapered or stepped longitudinal cross-sections.

    “Giving effect to “by movement relative to the receptacle,” when interpreting this phrase in combination with “a separation cartridge selectively removable from a receptacle,” requires that the separation cartridge is removable from the receptacle by movement of the separation cartridge itself. Interpreting the removal direction limitation to encompass a stationary separation cartridge, as Petitioner proposes, would render “by movement relative to the receptacle” superfluous. Specifically, Petitioner’s interpretation of “relative movement” does not accord weight to the recitation “movement relative to the receptacle,” which requires something other than the receptacle—the separation cartridge—to move in order for movement to occur with reference to or in comparison with the receptacle. Petitioner’s interpretation of “relative movement” as permitting removal of the separation cartridge from the receptacle when the separation cartridge remains stationary, is inconsistent with the plain language of removal direction limitation as a whole. The plain language of the removal direction limitation indicates that the separation cartridge must be removable from the receptacle by movement of the separation cartridge in a specified (first) direction. Claim 1 defines the first direction as a direction opposite the (second) direction in which the inlet and outlet are oriented. The plain language of the removal direction limitation, therefore, requires that the separation cartridge is removable from a receptacle by movement of the separation cartridge in comparison to the receptacle in a direction opposite the direction in which the separation cartridge’s inlet and outlet are oriented.” slip op. at 15

We start with an important observation: claim 18 (the only independent claim at issue) is an apparatus claim; the claim is directed to a “semiconductor light source.” Ex. 1001, 9:52, EPRC 1:32. One requirement of this apparatus is that it comprise “a semiconductor chip” (id. at 9:66) where “said semiconductor chip is a light emitting diode (LED) chip EPRC, 1:34–36.

Because of these recitations, Petitioner bears the burden of establishing that the prior art teaches or suggests a semiconductor LED chip “capable of emitting light greater than about 40 milliwatts.” As explained herein, we determine that in the Petition, Petitioner met this burden by establishing by a preponderance of the evidence that the Krames reference teaches an LED chip that has this capability. Pet. 53 (quoting Ex. 1008, 10). Notably, claim 18 does not require actual operation of anything at greater than 40 milliwatts because claim 21 is not a method claim.

Thus, a preponderance of the evidence supports Krames’s prior art status.

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
