      “6. Conclusions on the Sufficiency of Petitioner’s Information Petitioner shows sufficiently that the subject matter of at least one challenged claim would have been obvious based on the ground that asserts Sun. See Pet. 6 (Ground 3). We have concerns about the sufficiency of Petitioner’s showing with respect to the grounds that do not assert Sun. See id. (Grounds 1 and 2). We institute an inter partes review of all challenged claims based on all grounds asserted in the Petition. See SAS Inst., Inc. v. Iancu, 138 S.

      “The parties disagree about whether the ordinarily skilled artisan would have had specific “experience with dental appliances or access to individuals with such experience.” Prelim. Resp. 9; see Pet. 10–11 n.1 (disagreeing with that proposition). Neither party explains why a resolution of that dispute is necessary to this Decision to institute review. See, e.g., Prelim. Resp. 9 n.2 (“even under Petitioner’s proposed definition, the Petition fails to show a reasonable likelihood that any claim is unpatentable”); Pet. 14–15 & n.1 (arguing about the issue without explaining how a resolution of the dispute would change the outcome of the decision on institution).

We will resolve that dispute only to the extent necessary in any final written decision. Based on the information presented, we find that the asserted prior art itself is sufficient to demonstrate the level of skill in the art at the time of the invention. See Okajima v.

Pet. 12–15. Patent Owner does not provide arguments directed specifically to proposed claim constructions. See generally Prelim. Resp.

      “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. Pet. 65–66 (citing Ex. 1002 ¶¶ 158–160; Ex. 1015, 3:74–76; Ex. 1018 ¶ 4); see Sur-reply 5 (Patent Owner, identifying distinctions without a difference in Sun). 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. Patent Owner may address that preliminary finding in a timely response to the Petition.” slip op. at 16

      “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. Resp. 16–19 (citing Ex. 1007, 53, 95–96, 98–107, 143–147, 149, 167–168).

Prelim. Resp. 22–23. As Patent Owner correctly observes (id.), Petitioner’s general assertion that “Lipsker discloses that combinations of disclosed embodiments and features are possible and proper” (Pet. 20) does not constitute a reasoned explanation regarding why the skilled artisan would have combined Lipsker’s precoating and non-precoating actuator embodiments to arrive at the claimed subject matter.

      “Ma distinguishes between these two methods, noting that with the “active” method, “the forming quality of a previous layer does not influence the forming of the current layer,” while with the “passive” method, “the quality of a previous layer has a profound effect on the forming quality of the current layer.” Ex. 1007, 53. 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

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed petitioner constructionDecided for petitioner

      “The express language of claim 1 requires no solubility threshold, and dependent claim 10 of related U.S. Patent No. 10,288,620 B2 demonstrates that, where a solubility threshold was intended by the inventors of these patents, they knew how to expressly set forth that threshold in the claims. Compare Ex. 1004, 222:47–49 (“capable of imparting solubility in water”), with Ex. 1005, 218:12–14 (“The method according to claim 1, wherein each R is a non-ionic side group capable of imparting solubility in water in excess of 10 mg/mL.”). Thus, the claim language does not support applying a particular solubility threshold in claim 1. As noted by Patent Owner, the written description of the ’648 patent explains that “each R is independently a non-ionic side group capable of imparting solubility in water in excess of 10 mg/mL.” Ex. 1004, 2:21–22; Prelim. Resp. 17. This solubility threshold, however, is not in claim 1. Also, the ’648 patent states that this solubility applies only to some embodiments. See, e.g., Ex. 1004, 53:9–12, 55:6–20. We decline to import such a limitation from the written description into claim 1 absent reason for doing so. See SciMed Life Systems, Inc. v. Advanced Cardiovascular Systems, Inc., 242 F.3d 1337, 1340 (Fed. Cir. 2001) (explaining that “reading a limitation from the written description into the claims” is “one of the cardinal sins of patent law”); see also Thorner v. Sony Comp. Ent’m Am., LLC, 669 F.3d 1362, 1366 (Fed. Cir. 2012) (“It is likewise not enough that the only embodiments, or all of the embodiments, contain a particular limitation. We do not read limitations from the specification into claims; we do not redefine words.”). After considering the parties’ arguments and evidence presented, we agree with Petitioner that Patent Owner’s proposed definition reads into the claim a numeric threshold for solubility from an embodiment that is nowhere apparent from the claim itself. “[I]nterpreting what is meant by a word in a claim is not to be confused with adding an extraneous limitation appearing in the specification, which is improper.” In re Cruciferous Sprout Litigation, 301 F.3d 1343, 1348 (Fed. Cir. 2002) (internal quotation marks and citations omitted; emphasis in original). Although we must read a patent’s claims in light of the specification, see, e.g., Comark Communications, Inc. v. Harris Corp., 156 F.3d 1182, 1186 (Fed. Cir. 1998), that obligation does not authorize “reading a limitation from the written description into the claims.” SciMed Life Systems, Inc. v. Advanced Cardiovascular Systems, Inc., 242 F.3d 1337, 1340 (Fed. Cir. 2001). Confining the scope of “non-ionic side group capable of imparting solubility in water” to an unexpressed minimum solubility taken from only “some” embodiments encompassed by the ’648 patent crosses that line. See, e.g., E.I. du Pont de Nemours & Co. v. Phillips Petroleum Co., 849 F.2d 1430, 1432–34 (Fed. Cir. 1988) (Claims to a co-polymer improperly interpreted to include two properties). In view of the foregoing, we construe the phrase “a non-ionic side group capable of imparting solubility in water” to not require any particular numeric threshold of solubility.

ORDER For the foregoing reasons, it is ORDERED that pursuant to 35 U.S.C. § 314(a), an inter partes review of claims 1–10, 18, and 20 of the ’417 patent is hereby instituted with respect to the ground of unpatentability set forth in the Petition; and FURTHER ORDERED that pursuant to 35 U.S.C. § 314(c) and 37 C.F.R. § 42.4, notice is hereby given of the institution of a trial; the trial will commence on the entry date of this Decision.” slip op. at 44

Patent Owner agrees that a POSITA may have a Ph.D. degree or master’s degree in chemistry, but asserts that a POSITA would also have “some experience with fluorescence” in addition to a Ph.D. degree in chemistry and that the experience of a POSITA with a master’s degree in chemistry is alternatively “industry experience in the field of biological detection systems.” Prelim. Resp. 5–6 (citing Ex. 2001 ¶ 7). For purposes of this Decision, we need not resolve these differences between the parties’ definitions, because any differences do not affect our analysis.13 If either party believes that adopting its preferred definition of the level of ordinary skill would have a material effect on the outcome of this proceeding, the party should address this issue during the instituted trial. slip op. at 11

      “Petitioner contends that: A person of ordinary skill in the art (“POSITA”) at the time of filing the ‘228 Patent would have been a person having a bachelor's degree in science or engineering, for example in the fields of chemistry, chemical engineering, or biomedical engineering, with undergraduate research experience, coupled with at least three years of industry experience, that linked the fabrication of fibrous polymeric materials to performance requirements for scaffolds for the promotion of proliferation of biological cells and the growth and/or reconstruction of biological tissues. Pet. 11–12 (citing Ex. 1002 ¶¶ 112–116). In response, Patent Owner notes that all challenged claims recite electrospun fibers but that Petitioner’s proposed level of skill “requires (1) no coursework, training or experience with electrospinning and (2) improperly focuses on scaffolds for the promotion of proliferation of biological cells and the growth and/or reconstruction of biological tissues.” PO Resp. 7 (citing Ex. 2001, ¶¶ 38–39).

      “Upon review, we are unpersuaded that Petitioner has improperly mixed and matched disclosures from Johnson to arrive at an anticipatory reference. 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. Patent Owner has not directed us to anything in the disclosure of Johnson that indicates that this is a “distinct” teaching or embodiment, instead of a general description of the types of scaffolds that Johnson encompasses. We see no reason why the general disclosures regarding Johnson’s scaffolds should be limited to specific embodiments, or precluded from applying to the method of Example 1.” slip op. at 14

      “We are unconvinced by Petitioner’s arguments and evidence. While we recognize that the range of claim 3 is very broad, and it is possible that scaffolds having fiber diameters as set forth in Johnson could have a mean pore size falling within the range, inherency “may not be established by probabilities or possibilities.” Par Pharm., Inc. v. Twi Pharms., Inc., 773 F.3d 1186, 1196 (Fed. Cir. 2014). Nor does Petitioner sufficiently explain why a person of ordinary skill in the art would have understood the process of Example 1 to necessarily result in the claimed mean pore size. We are also persuaded by Patent Owner’s argument that Boland 2005’s disclosure of a fiber diameter similar to Johnson’s that nevertheless falls outside the claimed mean pore size range. We note that Petitioner never addresses Boland 2005 in its Reply. 4.

      “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. LLC, No. 2020-1333, 2022 WL 3147683, at *6 (Fed. Cir.

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.
