Patent Owner does not dispute the level of ordinary skill in the art. See generally Prelim. Resp. For purposes of this Decision, we adopt Petitioner’s proposal as reasonable and consistent with the ’847 patent specification and the prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “Petitioner does not propose any claim constructions, except to explain that the claim 7 limitation “the spacer further comprises an offset spacer, positioned between the gate and the spacer,” is “satisfied if one layer (an ‘offset spacer’) of the claimed ‘spacer’ lies between another layer of the ‘spacer’ and the gate.” Pet. 11. Patent Owner does not dispute Petitioner’s assertions or offer any claim constructions. See generally Prelim. Resp. Because resolution of Petitioner’s proposed construction is unnecessary to our analyses for purposes of this decision, we do not address the proposal here. See Realtime Data, LLC v.

Petitioner explains how Lan teaches or suggests each recitation of claim 1, and Petitioner’s position is supported by adequate evidence for institution. Id. (citing, e.g., Ex. 1003 ¶¶ 100–125). Petitioner, for example, persuasively compares the structure of Figure 12 of Lan to each limitation of claim 1. Id. Patent Owner does not dispute Petitioner’s contentions except to argue that Lan (and the Petition’s other asserted references) “Do Not Mention, Describe, or Concern ‘Raised Epitaxial Layers.’” Prelim.

      “The parties agree that experience could substitute for a degree, and vice versa. Pet. 3 (citing Ex. 1003 ¶¶ 19–21); Prelim. Resp. 9. The parties’ proposed levels of ordinary skill are substantially similar. Although we discern no difference in the outcome of this decision from choosing one over the other, we adopt Petitioner’s proposal for this decision. Only Petitioner’s proposed level is supported by testimonial evidence on the preliminary record, and it appears to be consistent with the problems addressed in the ’774 patent. See Ex. 1001, 1:16–52. Therefore, we adopt Petitioner’s proposal for this decision.” slip op. at 7

      “CLAIM CONSTRUCTION B. In an IPR, we construe a patent claim “using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b).” 37 C.F.R. § 42.100(b). This generally includes “construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” Id. The ordinary and customary meaning of a claim term “is its meaning to the ordinary artisan after reading the entire patent,” and “as of the effective filing date of the patent application.” Phillips, 415 F.3d at 1313, 1321. Neither Petitioner nor Patent Owner argues that we need to construe any claim terms explicitly. See Pet. 2–3; Prelim. Resp. 9. However, the parties’ positions depend on interpreting the claim language in a particular way, and we discuss the relevant claim language below in the context of the parties’ arguments regarding the prior art. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am.

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundInstituted

      “At this stage, we find Petitioner’s arguments persuasive and disagree with Patent Owner. Patent Owner appears to equate a “fabrication profile” with a toolpath description, but nothing in the plain language of claim 1 supports that narrow interpretation. The ’774 patent describes a “fabrication profile” broadly and states that the profile can simply “include the dictionary [of configuration information],” or be “used to determine which machineready representation is available or suitable for a target printer.” Ex. 1001, 23:49–52. The preliminary evidence suggests that Douglas’s “operational parameters” would count as a “fabrication profile” because it is “the basis for generation of a machine-ready representation of the three-dimensional model that is executable on the target printer.” Id. at 23:37–39; see infra Section III.C.8. We also disagree that Petitioner’s argument is impermissible hindsight, because it is based on the disclosures in Douglas and Mark, and Petitioner has articulated a sufficiently persuasive reason to combine those references without referring to the ’774 patent itself. See In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971) (an obvious rationale is not improper hindsight if it “takes into account only knowledge which was within the level of ordinary skill at the time the claimed invention was made and does not include knowledge gleaned only from applicant’s disclosure”). Finally, Petitioner appears to rely on Mark for providing a particular example of a fabrication profile, not to replace Douglas’s overall system in which the 3D printer can receive “operational parameters” rather than just G-code. See Pet. 8–10, 17–23; see also Ex. 1005 ¶ 41 (the print queue, which stores tool instructions, may be maintained locally on printers 204 or on print servers 208); see In re Mouttet, 686 F.3d 1322, 1332 (Fed. Cir. 2012) (“[A] determination of obviousness based on teachings from multiple references does not require an actual, physical substitution of elements.” (citing In re Etter, 756 F.2d 852, 859 (Fed. Cir. 1985) (en banc))).” slip op. at 19

      “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

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededNot reached

      “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. Cir. 1999) (“[O]nly those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy.”)). As further discussed below, we invite the parties to address claim construction at trial.” slip op. at 9

    • 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

Otherwise, Petitioner’s proposed definition is consistent with the level of skill reflected in the specification of the ’474 patent and the asserted prior art references. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).

      “Petitioner further argues that one of ordinary skill “would have reasonably expected success implementing the combination, especially as Buibas and Sinyavskiy describe highly similar systems involving spiking neural networks used for training/operating robots.” Pet. 15–16 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 70). Indeed, Petitioner contends, “Buibas itself confirms that its spiking neural network can be partitioned, while Sinyavskiy provides the details for doing so.” Id. at 16 (citing Ex. 1005 ¶ 92; Ex. 1003 ¶ 70). In response, Patent Owner argues that Petitioner’s obviousness analysis is flawed because “there is no articulated reasoning regarding what specific element of claim 45 Buibas . . . does not disclose.” Prelim. Resp. 19–20. In other words, according to Patent Owner, Petitioner “failed to perform a proper obviousness analysis because Petitioner has failed to identify anything in the claims that Buibas lacks disclosure of for Ground 1A.” Id. at 20. Based on the present record, we determine that Petitioner has set forth sufficient reasoning to support a motivation to combine Buibas and Sinyavskiy for purposes of institution, as well as sufficient reasoning to support the conclusion that one of ordinary skill would have had a reasonable expectation of success in making the combination. We do not agree with Patent Owner’s argument that Petitioner’s obviousness analysis is flawed because it fails to identify what is lacking in Buibas’s disclosure. To the contrary, Petitioner explains that Buibas “broadly suggests” that its spiking neural networks “can be partitioned into modules for different tasks or behaviors” but “discloses little detail about the partitioning,” and that Sinyavskiy’s more detailed disclosure of partitioning spiking neural networks would fill in these details. See Pet. 12–13, 14–15, 24. Petitioner also relies on Sinyavskiy’s more detailed disclosures concerning partitioning the network to satisfy limitations [45.1] and [45.6]. Id. at 23–27, 35. Thus, Petitioner has sufficiently identified what is missing in Buibas (a detailed disclosure of partitioning spiking neural networks) and how that missing information is provided by Sinyavskiy (by disclosure of specific techniques for partitioning spiking networks).” slip op. at 13
