      “Institution of a post-grant review is authorized by statute when “the information presented in the petition . . . would demonstrate that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” 35 U.S.C. § 324(a) (2018). Upon consideration of the parties’ submissions and the evidence of record, we determine that Petitioner has demonstrated that it is more likely than not that at least one claim challenged in the Petition is unpatentable. Further, Patent Owner has not persuaded us that it is appropriate to exercise our discretion not to institute review. Accordingly, we institute a post-grant review of all claims and all grounds asserted in the Petition.1” slip op. at 2

      “On this record, we do not find Patent Owner’s proposed experience level of at least five years in measurement and analysis of coefficient of friction to be supported. As to the necessity of experience in textile engineering and fiber science, Patent Owner’s position, although not supported by declarant analysis of the factors listed above, is consistent with the disclosure of the ’854 patent, which describes features of a mesh layer in textile and fiber terms. See e.g., Ex. 1001, 10:17–11:14, 12:65–13:8, 14:20–24. On the whole, however, we do not discern on this record how specific experience in textile engineering and fiber science of a person of ordinary skill would materially alter the outcome at this stage of the proceeding. For purposes of this decision only, we apply Patent Owner’s proposed definition of a person of ordinary skill in the art, except for the requirement of five years of experience in measurement and analysis of coefficient of friction. The level of skill in the art remains an open issue in this proceeding. Further submissions by the parties may include argument and evidence that would assist in the resolution of this issue at the close of trial.” slip op. at 8

      “Petitioner contends “no formal claim construction is necessary in this proceeding.” Pet. 10; Reply 1, 4. Patent Owner contends the terms “mesh layer” and “coefficient of friction” require construction. Prelim. Resp. 14–16; Sur-reply 2–5. We have considered the parties’ arguments and discuss them below with regard to each of the terms Patent Owner contends should be construed. Because our determination that Petitioner demonstrates at least one challenged claim meets the threshold for institution (see SAS Inst., 138 S. Ct. at 1359–60) is not based on construing the term “mesh layer” or “coefficient of friction,” we determine we need not construe either claim term at this stage of the proceeding. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageDisclaimer not foundDecided for petitioner

      “We agree with Petitioner that the ’854 patent specification does not include clear and explicit lexicography or a disclaimer that would support requiring “coefficient of friction” to be determined by a specific ASTM test method. The portion of the specification Patent Owner asserts as a definition of “coefficient of friction” (see Ex. 1001, 11:31–42) is a description of an embodiment; we find it does not express patentee intent to redefine the term. Further, the statement that “the coefficient of friction … may be determined using the … ASTM D1894 standard test method” (id. at 11:32–35) indicates that use of that specific test method is optional. Accordingly, in the absence of patentee lexicography or disavowal, we do not limit the scope of the term “coefficient of friction” to require that it be measured by a specific ASTM standard. Luminara Worldwide, LLC v. Liown Elecs. Co., 814 F.3d 1343, 1353 (Fed. Cir. 2016) (“Absent lexicography or disavowal, we do not depart from the plain meaning of the claims.”); In re Am. Acad. Of Sci. Tech Ctr., 367 F.3d 1359, 1369 (Fed. Cir. 2004) (“We have cautioned against reading limitations into a claim from the preferred embodiment described in the specification, even if it is the only embodiment described, absent clear disclaimer in the specification.”). We note that the ’854 patent specification sets forth a definition for the coefficient of friction between the surfaces of the mesh material and the slide surface. Ex. 1001, 4:38–46. As stated above, however, we do not expressly construe any claim term at this stage of the proceeding. Should the parties address the construction of “coefficient of friction” at trial, we will make a determination after the close of evidence and any hearing.” slip op. at 13

      “Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996) (“First, we look to the words of the claims themselves . . . to define the scope of the patented invention.”). Claim 1 recites a particle that comprises (1) a plurality of crystallites comprising (a) a first composition (i) having a layered α- NaFeO2-type structure and (ii) comprising lithium, nickel, and oxygen; and (2) a grain boundary between adjacent crystallites of the plurality of crystallites and comprising (a) a second composition (i) having the layered α-NaFeO2-type structure, a cubic structure, or a combination thereof, and (ii) a concentration of cobalt in the grain boundary greater than a concentration of cobalt in the crystallites. The plain language of claim 1 thus indicates that the grain boundary has a composition (i.e., a “second composition”) distinct from that of the adjacent crystallites (i.e., a “first composition”), and that the grain boundary may have the same structure (i.e., a layered α-NaFeO2-type structure) or a different structure (i.e., a cubic structure, or a combination of a cubic structure and a layered α-NaFeO2-type structure) than the adjacent crystallites. The plain language of claim 1 thus structurally distinguishes the grain boundary from the adjacent crystallites by specifying that the grain boundary has a concentration of cobalt greater than that of the concentration of cobalt in the crystallites.” slip op. at 9

      “Petitioner, however, does not provide any evidence to establish that any such identity of empirical formulas means that Lampe-Onnerud’s cathode material necessarily has the same microstructure as the particle of claim 1. In particular, even if the empirical formula of Lampe-Onnerud’s core material is the same as that of the ’317 patent’s first composition, Petitioner does not provide evidence establishing that it necessarily follows that Lampe-Onnerud’s core is a polycrystalline material having a plurality of crystallites separated by grain boundaries between adjacent crystallites. Nor does Petitioner provide evidence establishing that it necessarily follows from any identity between the empirical formula of Lampe-Onnerud’s coating material and the ’317 patent’s second composition that Lampe-Onnerud’s coating material necessarily is present in grain boundaries at a higher concentration than in crystallites, assuming that Lampe-Onnerud’s material is comprised of a plurality of crystallites having grain boundaries between adjacent crystallites. Furthermore, although Petitioner’s declarant, Dr. Aurbach, indicates that Lampe-Onnerud’s process “begins with a conventional lithium nickel oxide-base material . . . known to be comprised of secondary articles having agglomerated primary particles and grain boundaries,” Dr. Aurbach does not provide any objective evidence to substantiate this asserted knowledge in the art.

Ltd., 851 F.3d 1270, 1274 (Fed. Cir. 2017). Petitioner invites the same error the Federal Circuit identified in Nidec, where the Board erred by holding that “anticipation can be found even when a prior art reference fails to disclose a claim element so long as a skilled artisan reading the reference would ‘at once envisage’ the claimed arrangement.” Id.

      “Petitioner’s obviousness challenge relies on the same argument and evidence that it presents for anticipation of claim 1. Pet. 26 (section VII.A.1.iv addressing anticipation and the micro-controller limitation of claim 1); Pet. 50, 60, 71 (cross-referencing section VII.A.1.iv for obviousness challenge to independent claims 1, 10, and 18). The Petition presents reasons to combine Mieth and Balogh. Pet. 51–55. But Petitioner’s obviousness rationale does not modify Mieth’s load 20, which remains Pet. 52 (relying on “load 20 of Mieth” as part of the combination with Balogh). The Petition presents no rationale for modifying or replacing Mieth’s load 20 and presents no argument or evidence that it would have been obvious to modify Mieth’s circuit by adding or substituting a micro-controller. In short, the Petition and Holberg Declaration assert that the micro- controller limitation is expressly disclosed in Mieth and do not present or support any obviousness rationale for that limitation. Pet. 26, 50–55; Ex. 1007 ¶ 105. Petitioner presents a new theory of unpatentability in the Reply, arguing that “the differences between Mieth’s ‘load 20’ and the claimed micro-controller are such that the subject matter as a whole would have been obvious to a [POSITA].” Pet.

      “B. Conflicting Opinion Testimony Petitioner’s own witness, Dr. Giacomin, opines that an ordinarily skilled artisan “would have been familiar with various machines and methods that would have enabled the thermoforming of multilayer dental sheets into shapes that conform with the teeth (i.e., creating a dental appliance).” Ex. 1002 ¶ 25. Nonetheless, Petitioner does not contest Patent Owner’s evidence that Dr. Giacomin himself lacks that qualification. Compare Resp. 9–10 (citing Ex. 1002 ¶¶ 1–9, 17 & n.1), with Reply (nowhere contesting that evidence). Petitioner also leaves uncontested Patent Owner’s evidence that Dr. Osswald, by contrast, possesses “the required experience” with dental appliances, including thermoforming processes for their manufacture. Compare Resp. 10 (citing Ex. 2006 ¶¶ 2–8; Ex. 2007), with Reply (nowhere contesting that evidence). Dr. Giacomin possesses excellent qualifications in the field of polymer rheology, but on this record, he demonstrates no, or inadequate, familiarity or experience with methods of thermoforming dental appliances from polymeric materials, which by his own admission is a minimum qualification of the hypothetical person of ordinary skill in the art. Ex. 1002 ¶¶ 1–11 (statement of qualifications), App’x A (curriculum vitae). Patent Owner’s witness, Dr. Osswald, by contrast, has “experience with polymer materials used in dental appliances” and “shaping operations, including thermoforming” processes for such applications. Ex. 2006 ¶¶ 5, 6. Against that backdrop, where the two witnesses’ opinions differ about the level of ordinarily skill in the art of thermoforming processes for dental appliances at the time of the invention, we credit Dr. Osswald’s opinions over those of Dr. Giacomin.

      “In the absence of explanation by Petitioner, we are left to wonder why either of those two ranges reported in Sun would have been recognized as applicable, without modification, to the three-layer dental splint of Hinz. Starting with a commercially-available, two-layer sheet of hard-soft PC-TPU or hard-soft PETG-TPU thermoplastic polymers, Hinz bonds a third layer, consisting of hard PC or hard PETG, to the soft TPU layer of the two-layer material by a process of thermoforming. No prior art reference explains how that process would have been understood to affect the overall flexural modulus of the resulting three-layer, hard-soft-hard composition. Petitioner does not supply an adequate reason for combining Sun’s preferred flexural modulus range, reported for Sun’s dental appliances at a temperature of 23˚ C, to dental splints formed by Hinz from fundamentally different polymers and a fundamentally different process. See Pet. 65–68 (entirety of four-page analysis on this ground); Resp. 32–38; Sur-reply 7–14 (well-supported explanation of those fundamental differences); Reply 8–16 (Petitioner’s unpersuasive responsive positions). The flexural modulus of Sun’s dental appliance not only is temperature dependent but also varies with the flexural strength of the polymeric material at hand. Ex. 1018 ¶ 12. Too late in the Reply, Petitioner raises fact-intensive reasons why those differences would not have mattered to an ordinarily skilled artisan. Reply 8–16. In any event, we agree with Patent Owner that Petitioner glosses over “[f]undamental differences” between the polymers and processes of Sun and Hinz, differences that “are central to [the] motivation to combine inquiry” and undercut Petitioner’s view that an ordinarily skilled artisan would have understood either of Sun’s flexural modulus ranges to apply, without modification, to Hinz’s polymers and process.

See Pet. 35–36; Ex. 1008 ¶¶ 84–90. Patent Owner’s argument that Petitioner’s rationale for combining the references is insufficient because it repeats “catchphrases” from KSR is not persuasive. A sufficient rationale to demonstrate obviousness under KSR does not require a showing that a person of ordinary skill in the art would know how to physically combine structures taught by the references. The fact that the references and challenged patent describe the same problems in the industry supports that the references are analogous art, but does not necessarily demonstrate hindsight in an obviousness rationale. Further, Patent Owner’s argument as to problems faced in the field such as harsh environmental conditions is unsupported attorney argument. We disagree with Patent Owner that Mr. Hamdan’s testimony as to prior art methods of attaching mounting poles to guardrails in oil fields (e.g., Ex. 1008 ¶ 87) is unsupported.

Id. at 6. Following our Preliminary Guidance, the parties submitted further arguments concerning the term “for a pharmaceutical composition.” Patent Owner argues the term requires that the claimed process provide STS that is sufficiently pure for use in a pediatric patient (see RMTA 8–11) and that the word “drug” in the ’363 patent’s definition of “pharmaceutical composition” requires that the anhydrous STS is of sufficient purity for pharmaceutical use. Reply RMTA 3. Petitioner argues that the construction set forth in our Preliminary Guidance was correct. See Sur-reply RMTA 2–3. Having considered the arguments and evidence, we do not further construe the term “for a pharmaceutical composition” in this Decision because, as discussed in our analysis of obviousness below, it is not necessary to construe the term in order to determine whether Petitioner has met its burden of demonstrating by a preponderance of the evidence that proposed substitute claims 28 and 29 are unpatentable.

      “determine the evidence relied on by Petitioner does not support Petitioner’s position that a person of ordinary skill in the art would have been motivated to combine Levenson, Sherman, Edwards, and USP. Petitioner’s contention that it would have been obvious to a person of ordinary skill in the art to combine the teachings of Levenson with Sherman is based on Dr. Rogers’s testimony that “[b]oth references disclose synthesis of sodium thiosulfate pentahydrate.” Ex. 1008 ¶ 151; see Pet. 36, 38. Dr. Rogers further testified it would have been obvious to add Edwards’s dehydrating step to the preparation of STS pentahydrate “which is obtained following the teachings of Levenson and Sherman” because “Edwards itself discloses dehydrating [STS] pentahydrate.” Id. ¶ 154. The Petition included these arguments even though they were inconsistent with Petitioner’s previous statement, during the Sherman prosecution, that Levenson taught STS heptahydrate, and therefore “does not provide any teaching with respect to [STS] pentahydrate.” Ex. 2013, 97. This prior inconsistent statement undercuts Petitioner’s rationale for combining Levenson, Sherman, and Edwards in this proceeding. Moreover, Petitioner’s rationale for combining the references in this proceeding is inconsistent with its statements about Levenson during the Sherman prosecution. Recognizing this inconsistency, Petitioner now takes the position that the Petition and Dr. Rogers’s testimony were incorrect. Paper 32; see Tr. 21:14–22:7, 59:1–2 (reemphasizing that “Petitioner maintains the statements that it made in the Sherman prosecution regarding Levenson”). Petitioner attempts to rationalize the inconsistency between its statements in the Sherman prosecution (including that “Levenson does not provide any teaching with respect to [STS] pentahydrate”) and its position in this proceeding by arguing that Dr. Rogers relies on Levenson as teaching surface activation “regardless of any particular hydrates Levenson discloses.” Tr. 22:8–9. That argument is not persuasive, because Dr. Rogers’s declaration clearly states the primary reason for his opinion that it would have been obvious to a person of ordinary skill in the art to combine the teachings of Levenson with Sherman: “[b]oth references disclose synthesis of sodium thiosulfate pentahydrate.” Ex. 1008 ¶ 151. Contrary to Petitioner’s argument, Dr. Roger’s reliance on the surface activation teachings of Levenson is because he believes that both references pertain to STS pentahydrate; the surface activation teachings are not stated as an independent reason to combine the references. Id. Petitioner provides no further explanation of how a person of ordinary skill in the art would have been motivated to combine Levenson’s teachings regarding manufacture of STS heptahydrate with Sherman’s and Edwards’s teachings regarding STS pentahydrate, or how a person of ordinary skill would have regarded the difference between STS hydrates. Dr. Rogers’s acknowledgement of stability differences among STS hydrates highlights the insufficiency of Petitioner’s showing in this regard. See Ex. 2005, 35, 39.
