      “According to Petitioner, claim 1’s recitation of “at an angle” in the context of “at least a pair of integral multi-faceted side walls that extend from opposite sides of the base member at an angle” should be construed as “at a same angle.” Pet. 9. According to Petitioner, “at an angle” only has meaning if it modifies both side walls and, thus, is the same angle. Id. Petitioner also cites the ’881 patent’s embodiments where the side walls extend from a base at the same angle. Id. (citing Ex. 1001, Figs. 16–20, 25). Patent Owner contends that the article “a” or “an” means “one or more” and that the plain language of the claim does not depart from that general rule to limit “a” or “an” to mean “one.” Prelim. Resp. 11. Patent Owner also asserts that the ’881 patent’s disclosure does not rise to an express disclaimer of that ordinary meaning of “a” or “an.” Id. at 12–13. Because it is not necessary to construe this claim term to resolve the dispute between the parties with respect to institution of trial, we do not make any claim construction at this stage in the proceeding. See Nidec Motor Corp. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“[W]e need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am.

      “knowledgeable and able to provide additional bends in Medendorp’s aluminum reflector to further direct the light emitted” and that Barr’s reflector design includes multi-faceted side walls, these facts alone are not enough to demonstrate that a POSITA would have been motivated to modify Medendorp’s reflector in the manner set forth in Petitioner’s challenge. Our reviewing court has held that merely asserting that references are drawn from the same field of art is “simply too conclusory” to show that a POSITA would have combined the references in the way of the claimed invention. Securus Techs., Inc. v. Glob. Tel*Link Corp., 701 F. App’x 971, 976 (Fed. Cir. 2017); see also Microsoft Corp. v. Enfish, LLC, 662 F. App’x 981, 990 (Fed. Cir. 2016) (determining that “the Board correctly concluded” that a petitioner “did not articulate a sufficient motivation to combine” where the only reason given was “that references were directed to the same art or same techniques.”). At most, the similarities between Medendorp and Baar establish, as a threshold matter, that they would have been considered by a POSITA. See K-Tec, Inc. v. Vita-Mix, Corp., 696 F.3d 1364, 1375 (Fed. Cir. 2012) (to qualify as prior art in an obviousness analysis, references must be analogous art—either in the same field of endeavor, or reasonably pertinent to the problem with which the inventor is involved). But the asserted similarities alone are not sufficient to show that a POSITA would have had a reason to combine the teachings in the manner described in the challenged claims. Personal Web Techs., LLC v. Apple, Inc., 848 F.3d 987, 994 (Fed. Cir. 2017) (It is not enough that a skilled artisan, once presented with two references, would have understood that they could be combined; Petitioner needs to establish a motivation to pick out the two references and combine them to arrive at the claimed invention.). Petitioner asserts that a POSITA would have been motivated to modify Medendorp’s reflector “to provide additional bends . . . to further direct the light emitted.” Pet. 32 (citing Ex. 1003 ¶ 230). Petitioner does not explain how modifying Medendorp’s reflector to include “additional bends” would improve directing the light emitted, when Medendorp already teaches that its reflector focuses and directs the LED’s emitted light. Id. Petitioner fails to provide any persuasive argument or evidence as to how replacing Medendorp’s reflector with Barr’s or retrofitting Barr’s fluorescent fixture with Medendorp’s LEDs would have provided any benefit to Medendorp’s LED fixture. According to Petitioner, “a POSITA would have understood Medendorp’s reflectors are merely exemplary and varying types and reflector shapes existed, but Petitioner fails to explain why Barr’s reflector in particular would be selected from among existing reflector shapes. See In re Schweickert, 676 F. App’x 988, 995 (Fed. Cir. 2017) (reversing Board’s obviousness determination where proposed modification of prior art is “unnecessary” to prior art system that “already” performs function of proposed additional feature and “would do little more than add unwanted cost and complexity to the system”).” slip op. at 23

In Petitioner’s view, an ordinarily skilled artisan “would have at least a bachelor’s degree in a relevant scientific field, e.g., physics, materials science or engineering, or electrical engineering, and two or more years of experience in lighting design with LED fixtures for lighting applications.” Pet. 2–3 (citing Ex. 1003 ¶¶ 36–47). Patent Owner does not challenge Petitioner’s definition for purposes of this Decision. Prelim. Resp. 11. On this record, we determine that the level of ordinary skill in the art at the time of the invention is reflected adequately in the asserted prior art references. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “The critical question is not whether any ordinarily skilled artisan could have undertaken the proposed modification, but rather, whether Petitioner explains adequately why one would have done so. See Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015) (“obviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed invention”); see also Trivascular, Inc. v. Samuels, 812 F.3d 1056, 1066 (Fed. Cir. 2016) (“Although the KSR test is flexible, the Board ‘must still be careful not to allow hindsight reconstruction of references . . . without any explanation as to how or why the references would be combined to produce the claimed invention.’”) (quoting Kinetic Concepts, 688 F.3d at 1368). On that point, Petitioner submits, “Medendorp’s reflectors are merely exemplary” and other “varying reflector shapes” would have been known in the art. Pet. 55–56. From there, Petitioner argues that an ordinarily skilled artisan “could” retrofit Baar’s multi-faceted side walls to include Medendorp’s LED lighting system. Id. at 56–57. By way of support, Petitioner indicates, “It would have been an obvious design choice to use such a multi-faceted reflector in the Medendorp light assembly if a greater focus of light was desired. (cite).” Id. at 57. We detect the unmistakable taint of hindsight reconstruction in Petitioner’s argument, including the conclusory and ineffective reference to a “cite” not provided.

Those prior art pH ranges overlap or encompass the specified pH range of “between 7.0 and 9.0.” Pet. 38–39 and n.10. Under these circumstances, the burden of production shifts to Patent Owner to come forward with evidence of the criticality of the specified pH range limitation. See id. at 39–40 (quoting E.I. DuPont de Nemours & Co. v. Synvina C.V., 904 F.3d 996, 1008 (Fed. Cir. 2018). Patent Owner meets that burden by directing us to the Marchi Declaration. Resp. 9–12; Ex. 1004, 432–440. That evidence contains experimental results that support Dr. Marchi’s opinion that the claimed method, when performed at a pH of 8, “can be run with equimolar amounts of oxidant without increasing depolymerization,” but when performed at a pH of 10, results in an undesirable “depolymerizing attack on the main chain, even employing only 0.9 equivalents of oxidant.” Ex. 1004, 434–435 (¶ 7). As Patent Owner points out, moreover, the oxidation reaction in each of the examples in Geisser is carried out at a pH of 10. see Prelim.

      “We assess the ground based on anticipation by Geisser in view of the principle that a prior art reference anticipates a patent claim “if it discloses every claim limitation.” In re Montgomery, 677 F.3d 1375, 1379 (Fed. Cir. 2012). The ground based on anticipation by Geisser rests on a conclusory opinion that Geisser’s disclosure of a pH range between 8 and 12 “describes” an oxidation reaction that occurs “at a pH between 7.0 and 9.0.” Pet. 63 (citing Ex. 1002 ¶ 178, which repeats that conclusory opinion verbatim without objective evidence or analysis). It is unclear on this record, and Petitioner does not explain adequately, how or why Geisser anticipates the pH range limitation of claim 1, which is “critical” for reasons explained above in our analysis of the ground based on obviousness over Geisser and Stoll. Ex. 1004, 435 (the Marchi Declaration, ¶ 7). Accordingly, on this record, we determine that Petitioner does not establish a reasonable likelihood of prevailing “with respect to at least [one] of the claims” based on any ground asserted in the Petition. 35 U.S.C. § 314(a).” slip op. at 13

Patent Owner does not contest Petitioner’s proposed definition in the Preliminary Response. Prelim. Resp. 17–18.

T-Mobile USA, Inc., 522 F.3d 1299, 1306 (Fed. Cir. 2008); see also In re NTP, Inc., 654 F.3d 1268, 1276 (Fed. Cir. 2011) (“[A] patent’s claims are not entitled to an earlier priority date merely because the patentee claims priority. Rather, for a patent’s claims to be entitled to an earlier priority date, the patentee must demonstrate that the claims meet the requirements of 35 U.S.C. § 120.” (citations omitted)). The written-description inquiry is a question of fact, is context-specific, and must be determined on a case-by-case basis. Ariad banc). The test for sufficiency of support is whether the disclosure of the application relied upon “reasonably conveys to the artisan that the inventor had possession at that time of the later claimed subject matter.” Vas-Cath Inc. v. Mahurkar, 935 F.2d 1555, 1563 (Fed. Cir. 1991). “One shows that one is ‘in possession’ of the invention by describing the invention, with all its claimed limitations . . . .” Lockwood v. Am. Airlines, Inc., 107 F.3d 1565, 1572 (Fed. Cir. 1997). We determine that Patent Owner has not demonstrated, at this stage of the proceeding, that the Challenged Claims are entitled to claim priority to the second German application, and, as such, Jarisch ’929 is prior art on the current record. We determine that Patent Owner has not sufficiently demonstrated that the second German application provides written description support for at least the identifier as recited in independent claims 1, 7, and 10. We determine, at this stage of the proceeding and on the current record, that the embodiment of Figures 16, 17, and 18 does not show an identifier with a repeat pattern on the bottom side of the flange as required by the claims. The disclosure of the second German application explains that the means 2.4.2 is a toothed ring, with the teeth formed in the outer circumference of the flange, not on the bottom of the flange. See, e.g., Ex. 1047, 41:17–27 (explaining that the annular peripheral region 2.4 has “in its outer region” means 2.4.2 (emphasis added)); id., Fig. 18 (showing that the outer edge of the flange interacts with pinion 24).” slip op. at 23

Factors pertinent to a determination of the level of ordinary skill in the art include: (1) educational level of the inventor; (2) type of problems encountered in the art; (3) prior art solutions to those problems; (4) rapidity with which innovations are made; (5) sophistication of the technology; and (6) educational level of workers active in the field. Env’t Designs, Ltd. v. Union Oil Co., 713 F.2d 693, 696–97 (Fed. Cir. 1983) (citing Orthopedic Equip. Co. v. All Orthopedic Appliances, Inc., 707 F.2d 1376, 1381–82 (Fed. Cir. 1983)). Not all such factors may be present in every case, and one or more of these or other factors may predominate in a particular case. Id.

    • Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner

      “That prior art disclosure of elastomeric materials for use as the outer layers in an unclaimed and disfavored soft-hard-soft layer configuration does not convey, with reasonable clarity, that the inventors had possession of the claimed subject matter, in which the elastomeric material forms the inner layer of a polymeric sheet in a hard-soft-hard layer configuration. See id. ¶¶ 7, 33–35, 109–110. Even if the hardness limitation of the challenged claims would have been obvious from the relied-upon disclosure of the ’176 application (Ex. 2001 ¶ 109), that circumstance is insufficient to establish written description support. “Entitlement to a filing date does not extend to subject matter which is not disclosed, but would be obvious over what is expressly disclosed.” PowerOasis, Inc. v. T-Mobile USA, Inc., 522 F.3d 1299, 1306 (Fed. Cir. 2008) (quotations omitted); see Pet. 21 (quoting that precedent).

Pet. 40; see Ex. 2001 ¶ 109 (describing elastomeric materials, having the specified hardness, only in the context of an unclaimed prior art soft-hard-soft embodiment). On this record, we preliminarily agree with Petitioner that the earliest effective filing date to which the ’263 patent appears to be entitled is December 18, 2019, namely, the filing date of the ’256 application, from which the ’263 patent issued.

If either party believes that the difference in level of skill would have a material effect on the analysis of the patentability of the challenged claims, that issue should be specifically addressed in briefing during the trial. We will resolve that dispute only to the extent necessary in any final written decision.

      “We preliminarily find that Hinz would have alerted the ordinarily skilled artisan that the choice of “layer thicknesses” in a multilayer dental structure “ensure[s] very good mechanical properties.” Ex. 1002 ¶ 100; Ex. 1015, 4:116–119. Where Sun teaches that the flexural modulus of dental structures would have been recognized as one such mechanical property (id. ¶ 160; Ex. 1018 ¶ 12), we further accept, at this preliminary stage, that an ordinarily skilled artisan would have understood how variations “in the relative thicknesses of the respective layers” desirably impact the flexural modulus (id. ¶ 105). Furthermore, in view of Sun’s disclosure of advantages associated with dental structures having a preferred flexural modulus, and the fact that those exact same advantages expressly were of interest to Hinz, we are not persuaded by Patent Owner’s argument, on this record, that it makes a difference that Sun discusses two-layer structures, whereas Hinz discusses three-layer structures.

In other words, Sun’s teachings appear, on this record, to apply generally to multilayer dental structures, including the multilayer structures of Hinz. For the above reasons, although the issue is a close one, we find that Petitioner shows sufficiently for purposes of trial institution that the ordinarily skilled artisan would have had a reason, and possessed the technical acumen, to select combinations of layer thickness values, from among the ranges disclosed in Hinz, to attain a multilayer dental structure having a desirable flexural modulus, as suggested by Sun.

      “The question of whether the prior art references are in the same field of endeavor is merely a threshold issue that must be satisfied before an obviousness determination can be made. See K-Tec, Inc. v. Vita-Mix, Corp., 696 F.3d 1364, 1375 (Fed. Cir. 2012) (to qualify as prior art in an obviousness analysis, references must be analogous art—either in the same field of endeavor, or reasonably pertinent to the problem with which the inventor is involved). In other words, once it is determined that the prior art is analogous to the claimed invention, it is then necessary to show that it would have been obvious for the skilled artisan to select and combine the teachings of the prior art in the manner claimed. Thus, we agree with Patent Owner that the Petition needs to set forth specific reasoning as to why an ordinarily skilled artisan would have been motivated to combine these references even if they are in the same or similar fields. Prelim. Resp. 31. Petitioner fails to do so on this record. The absence of such reasoning is particularly noteworthy here in view of Ma’s numerous teachings which appear to discredit the “passive” method of pulling the composite strand from the extruder as recited in claim 4, which is challenged in each of Grounds 2 and 3. Patent Owner identifies no fewer than eight disclosures within Ma that seemingly disparage the passive “pulling” method and discuss benefits of the active “pushing” method. Prelim.

Ma sets forth other problems with using the “passive” method. See, e.g., id. at 95–96, 98–107, 143, 145–147, 149. For example, Ma teaches that during deposition using the “passive” method, “it is possible to make a big error, especially when the nozzle makes a big-angle turn” (id. at 98), and that “[a] toolpath error could be generated if an anchoring point is not formed properly” when using the “passive” method (id. at 143). Ma also discloses that forming speed is an issue with the “passive” method, (id. at 146), but discloses “[o]ne of the advantages [of the ‘active’ method] is that the forming speed is not limited by the solidification condition of the towpreg during the forming process” (id. at 168). 2. Analysis Claim 1 recites, inter alia, “moving the nozzle away from the anchor during discharging to pull the path of the composite material out of the nozzle.” Ex. 1001, 10:61–63. Petitioner contends that Ma teaches this limitation because “Ma discloses that ‘when the object moves relative to the nozzle during the forming process, the towpreg is pulled out by the object instead of being pushed out by nozzle pressure” and “the anchor points are used to pull the towpreg (‘the path of the composite material’) out of the nozzle during discharging.” Pet. 33 (citing Ex. 1007, 38, 72)(emphasis omitted). controlled layer manufacturing: an “active” method that pushes the composite material from an extruder’s orifice, and a self-anchoring or “passive” method, wherein the composite material is pulled out by the object. Ex. 1007, 7–8, 52–54. Here, Petitioner relies on Ma’s disclosures relating to the passive method. Petitioner, however, fails to provide a persuasive explanation as to why a POSITA would have selected Ma’s passive pulling method over Ma’s active pushing method for further development or improvement. Petitioner’s failure to do so is particularly noteworthy here, because Ma includes numerous teachings against the passive method of pulling the composite material through the nozzle. Indeed, Patent Owner identifies no fewer than eight disclosures within Ma that seemingly disparage the passive pulling method and discuss the benefits of the active pushing method. Prelim. Resp. 7–10 (citing Ex. 1007, 53, 95– 96, 98–107, 143–147, 149, 167–168). We also agree with Patent Owner that Petitioner has not sufficiently explained why the ordinarily skilled artisan would have combined Ma’s active and passive methods, much less with a reasonable expectation of successfully arriving at the subject matter of claim 1. Id. at 11–14. In the absence of any explanation from Petitioner, we are not persuaded that a POSITA would have ignored Ma’s teachings against the passive pulling method and selected Ma’s pulling method over Ma’s active pushing method for further development and improvement. Accordingly, Petitioner has not demonstrated a reasonable likelihood that claim 1 would have been obvious over Ma.” slip op. at 8

Patent Owner is correct that Petitioner primarily relies on Example 1 as evidence for the method by which its scaffold is made. But the disclosure found in paragraph 98 is not a “distinct” teaching of the type described in Net MoneyIN; rather, it is a general description of the structures that may be created by Johnson’s method: “A scaffold may comprise any number of layers, including about 1 layer, about 2 layers, about 3 layers, about 4 layers, about 5 layers, and so on.” Ex. 1009 ¶ 98.
