    “overlap to a significant degree, i.e., a person with a Ph.D. in a discipline related to biological sciences and having had at least two years of work experience. However, the parties’ proposals differ slightly in the specific subjects in which a POSA would have had a doctoral degree, and whether the person’s work experience must have been directly related to horseshoe crab Factor C. As an initial matter, we find that a rigid requirement as to the subject of a POSA’s doctoral degree (e.g., biochemical engineering, enzymology), or experience working specifically with horseshoe crab proteins, is not consistent with the evidence of record. See, e.g., Ex. 1067, 20:23–21:2 (Dr. Schaefer testifying that the fact the “name of [his] Ph.D. is immunology . . . does not change the fact that the core of [his] thesis training was really in molecular biology”), 22:3–15 (explaining “the fact that the production of proteins recombinantly is mostly species agnostic”); Ex. 1069, 45:20–47:17 (Dr. Morris testifying that whether a person is a POSA depends on the person’s “experience, [ ] publications,” and work done for the Ph.D. rather than the name of the Ph.D. program). We also find that evidence of record supports Petitioner’s assertion that, for purposes of defining a POSA, “[m]ore education could substitute for experience, and vice versa.” See, e.g., Pet. 19; Ex. 1065, 99:14–100:3. with respect to the claims of the ’318 patent would have had a Ph.D. in molecular biology, biochemistry, or a related discipline, and about two years of experience with cloning genes, expressing cloned genes as proteins, and/or characterizing such cloned genes and proteins, with more education being able to substitute for experience, and vice versa.

Neither do we see Petitioner’s arguments regarding the December 10, 2013 priority date to be “mutually opposed” as Dr. Schaefer testified. Ex. 1067, 216:4– 24. Instead, we credit evidence of record, including Dr. Jain’s testimony and the February 22, 2018 Mizumura Declaration, that existence of the full sequence would permit a more complete analysis and that such an analysis would provide a POSA with a reasonable expectation that the claimed L. polyphemus recombinant protein would have a residual activity within the claimed range. See, e.g., Ex. 1029, 2–5; Ex. 1010, 48; Ex. 1065, 117:14– 130:24 (explaining that comparison of partial sequences in the Tokunaga 1991 publication showed “difference around the cleavage site” between T. tridentatus and L. polyphemus but comparison of the full sequence revealed that “the catalytic triad of histidine, serine, aspartate . . . to be more similar between Tachypleus and Limulus”). Patent Owner asserts that “Petitioner’s reliance on a statement made by Dr. Mizumura in a declaration submitted during prosecution of the ’767 Application fails to fill the gap in the analysis” regarding reasonable expectation of success, because the declaration “offers no evidence of the percentage of conserved amino acid substitutions that exist to support the conclusion that a POSA would have expected residual activity to be maintained between Tachypleus tridentatus and Limulus polyphemus” PO Resp. 47. However, as noted above, Dr. Mizumura provides an alignment of Factor C proteins from the two different species of horseshoe crab, determines that the similarity between the amino acid sequence is 99.5%, states that the amino acid residues that can undergo N-type sugar chain that L. polyphemus, like T. tridentatus, would also be less susceptible to inhibition by ions. Ex. 1029, 4–5. For the reasons discussed above, we also disagree with Patent Owner’s assertion that Petitioner’s reasonable expectation of success argument is “nothing more than conclusory assertions with no support.” PO Resp. 46. Rather, we find Petitioner has shown, by a preponderance of the evidence, that a POSA would have had reason to combine the teachings of Mizumura and the ’498 PCT, with a reasonable expectation of success in arriving at the Factor C protein recited in claim 21.” slip op. at 38

    “Petitioner has the better position. Huang2 teaches crosslinking and provides a reason for doing so (stability). In particular, Huang2 states: “To better mimic skin ECM, electrospun collagen fibers have been fabricated, however, the rapid degradation and poor mechanical properties determine that either crosslinking or combination with other materials is necessary to obtain a stable scaffold.” Ex. 1005, 1791 (emphasis added). It is true that, in describing work actually carried out, Huang2 states that blending with PCL was performed and does not mention crosslinking. See id. at 1792 (“Nanofibrous matrices of PCL and Collagen at a weight ratio of 3:1 were fabricated using electrospinning as previously described.”). However, the prior art – here, Huang2 – is not limited to that which it describes having created. See In re Mills, 470 F.2d 649, 651 (C.C.P.A. 1972) (“a reference is not limited to the disclosure of specific working examples”); see also In re Lemelson, 397 F.2d 1006, 1009 (CCPA 1968) (“The use of patents as references is not limited to what the patentees describe as their own inventions or to the problems with which they are concerned. They are part of the literature of the art, relevant for all they contain.”); In re Fritch, 972 F.2d 1260, 1264 (Fed. Cir. 1992) (“It is well settled that a prior art reference is relevant for all that it teaches to those of ordinary skill in the art.”). Huang2 teaches two stabilization methods when using collagen in scaffolds. Huang2 states that one or the other “is necessary to obtain a stable scaffold” (when using collagen), but it does not preclude or teach away from using Patent Owner-cited testimony of Dr. Mikos is not as definitive as Patent Owner suggests; Dr. Mikos’s testimony is that a person of ordinary skill in the art “typically would not have done both.” Ex. 2015 ¶64 (emphasis added). The bottom line is that Huang2 teaches the person of ordinary skill in the art two ways to stabilize scaffolds/matrices comprised of collagen, provides a reason for doing so (stability), and does not teach away from using both. We are persuaded that a “scaffold comprising crosslinked fibers comprising collagen” would have been obvious in view of the cited teachings of Huang2.” slip op. at 33

    “We are not persuaded by Appellant’s citations to either reference. As discussed above, Petitioner’s Ground 1 is premised on a person of ordinary skill in the art altering the native flat sheet structure of Huang2 by rolling it into a jelly-roll structure as taught by Kuo. See Pet. 41 (Beginning its claim 2 arguments with the following: “Claim 1 is obvious for the reasons expressed above in § X.A., supra, which are incorporated herein.”); see also Pet. Reply 17 (“[B]ased on the explicit teaching of Kuo, a POSA would have been motivated to take the electrospun flat scaffold made by the techniques of Huang2, seed it with the desired cells, and roll it to treat a tendon and ligament.” (emphasis added)). Indeed, the paragraphs of Kuo that Petitioner cites for disclosing “scaffold sheets,” explicitly describe rolling them into jelly-roll like structures. See Ex. 1018 ¶7 (stating that “the sheet is spirally contacting a scaffold sheet of fibrous material with a cell; and rolling the scaffold sheet in a jelly-roll like manner to form a spirally wound tissue construct”), ¶22 (describing a method comprising “forming a tissue construct by contacting a scaffold sheet of fibrous material with a cell; and rolling the scaffold sheet in a jelly-roll like manner to form a spirally wound tissue construct” and implanting it in a patient). Petitioner fails to argue that that “one or more elongated sheets” recited in claim 2 would encompass the rolled structure of its proposed modification. Nor does Petitioner articulate a claim construction argument that could support such an argument.

Covad Communications Group, Inc., 262 F.3d 1258, 1268 (Fed. Cir. 2001). Among the criteria to consider in whether the patentee acted as a lexicographer to define a claim term include (a) whether the patent specification included the statement in question under a section for marks, (c) whether the sentence uses the term “refer to,” which generally “conveys an intent for [that sentence] to be definitional,” and (d) whether there are other non-limiting terms (e.g., “for example,” or “include”) that contradict a definitional intent.

We determine that this language satisfies at least two of the criteria set forth in Alnylam. Specifically, the sentence at issue sets out “major peaks” in quotation marks, and then uses the term “refers to” to explain what qualifies as major peaks. That is not the end of the inquiry, however, as we find there is still some ambiguity as to whether the patentee intended to define “major peaks” so as to require so-called “minor peaks” in the claimed invention.

    “As discussed above, we agree with Patent Owner that the sentence it cites from the Specification of the ’223 patent bears sufficient hallmarks of lexicography. However, the Specification nonetheless lacks any indication that so-called “minor peaks” are a necessary component of the claimed invention. “Although it is firmly settled that an applicant may act as a 9 Figure 8B does not contain “major peaks” despite clearly depicting two “peaks higher than the average of the [three or possibly four] peaks in the result” because none of the peaks is a reflection of fiber alignment. 10 After presenting claim construction arguments based on Ayres 2008, Patent Owner confusingly states: “Finally, whether Ayres-2008 supports [Patent Owner’s] construction is irrelevant.” PO Sur-Reply 5 (emphasis added). definition that is contrary to the ordinary meaning of a claim term unless it communicates a deliberate and clear preference for this alternative definition.” Kumar v. Ovonic Battery Co., 351 F.3d 1364, 1368 (Fed. Cir. 2003). There is no indication that the patentee sought to require “minor peaks” within the scope of the claimed invention. Nor are we persuaded that a person of ordinary skill in the art would readily understand the scope of the term “major peaks” to require non-major peaks. We interpret the Specification’s statement that “‘major peaks’ herein refer to peaks higher than the average of the peaks in the result” (Ex. 1001, 13:6–7) to be teaching a person of ordinary skill in the art how to identify or discern “major peaks,” which indicate a principal axis of alignment, from any non-major peaks, which would be caused by something else. We conclude that a person of ordinary skill in the art would consider “major peaks” as used in the ’223 patent as referring to peaks that reflect the sole axis or primary axis of fiber alignment. See, e.g., id. at code (54) (“ALIGNED FIBER AND METHOD OF USE THEREOF”), code (57) (“A scaffold comprising an aligned fiber.”), 1:6–7 (“The invention relates to an aligned fiber and method of use thereof.”), 1:11–12 (“The invention relates to a scaffold comprising an aligned fiber.”), 13:16–17 (“Alignment of the fibers in the scaffold may be measured by a fast Fourier transform (FFT) analysis.”). This would certainly include peaks materially higher than the average of the peaks in the result, but it would not be limited to situations involving peaks of different heights or require so-called minor peaks.

    “Petitioner argues that, for the aligned sample, a major peak occurs at about 90° as identified by Petitioner’s annotation (red arrow). Pet. 30–31. As support, Petitioner directs us to Huang2’s explicit description of what the peak indicates, namely that “[t]he narrow peak of the normalized intensity values in anisotropic [aligned] matrices (Figure 1C) indicated that PCL/Coll nanofibers aligned along a single axis (Fig. 1B).” Id. at 31 (alterations in original) (quoting Ex. 1005, 1794). Patent Owner disputes that the illustrated peak is a major peak solely based on the lack of any lesser peaks. See PO Resp. 13 (“[T]he height of the sole peak is identical to—not higher than—the average height of the peaks in the result.”). As discussed above, however, we do not construe “major peaks” as requiring the existence of non-major peaks. We find that the illustrated peak in the Aniso plot of the FFT analysis results (Figure 1C) is a major peak within the meaning of the claim. The evidence in support of this finding is overwhelming. First, the term “Aniso” as used in Huang2 refers to fibers “with alignment.” Ex. 1005, 1792. Huang2 describes fabricating such matrices of aligned fibers with electrospinning, the same method used to impart alignment in the ’223 patent. Id. at 1791–92. Huang2 visually confirms that the fibers in fact are aligned via scanning electron microscopy. Id. at Fig. 1B. Further, Huang2 explicitly states that the peak illustrated in the Aniso plot of the FFT analysis results (Figure 1C) is caused by the fact that the “PCL/Coll nanofibers aligned along a single axis (Fig. 1B).” Id. at 1794. This is precisely what electrospinning may yield aligned fibers and images of aligned fibers will yield FFT results with major peaks. Ex. 1001, 2:18–19, 4:46–60, 13:16–26. Additionally, Huang2 itself considers the peak illustrated in the Aniso plot of the FFT analysis to be significant, stating: “In contrast [to the Aniso plot], the lack of a significant peak for the fibers collected on a stationary surface [(i.e., without electrospinning)] demonstrated no preferred fiber orientation in the isotropic matrices” (i.e., the Iso plot). Ex. 1005, 1794. Indeed, the asserted major peak in the Aniso plot shown in Huang2’s Figure 1C is higher than any other data point on the plot. For these reasons, we find the peak to be a major peak.15 Petitioner acknowledges that Figure 1C only reports its results” slip op. at 32

    “claim 15). We agree that the Specification supports Patent Owner’s construction. Although Petitioner bases its construction on extrinsic evidence, Petitioner argues that its construction “is consistent with” the intrinsic evidence, which, according to Petitioner, “indicates a sole is optional.” Pet. 31. A sole is optional, Petitioner argues, because the Abstract of the ’511 patent states that “[t]he footwear may include an upper and a sole structure.” Pet. 31 (quoting Ex. 1001, Abstr. (Petitioner’s emphasis)). We are not persuaded. Petitioner reads too much into the sentence it quotes from the Abstract and its use of the word “may.” Indeed, by Petitioner’s logic, both the upper and the sole structure would be optional and footwear would lack any required structure. Petitioner also argues that “[o]ther intrinsic evidence” supports its construction. Pet. 31–32 (citing Ex. 1053, 4:55–58; Ex. 1002 ¶92). The alleged intrinsic evidence, however, is an unrelated patent, US 2,675,631, which purportedly was cited during the prosecution of the ’511 patent. Id. This argument is undeveloped by Petitioner.

Tyco Healthcare Grp., LP, 616 F.3d 1249, 1254 (Fed. Cir. 2010) (quoting Gaus v. Conair Corp., 363 F.3d 1284, 1288 (Fed. Cir. 2004)) (alteration in original). Thus, the claim language suggests that the “integral knit tongue” is a component distinct, at least to some degree, from the “upper.” See also Ex. 1001, 2:27–28 (the Specification stating that “[a] knitted component including the upper and an integral knit tongue is incorporated into the article of footwear.”). Limitation 1d reinforces this understanding by requiring the tongue to be joined to a portion of the throat area of the upper.

Ex. 2014, 18–19 (defining “Throat”: “The main opening of a shoe extending from the vamp [(the front part of a shoe upper that covers the toes and part of the foot)] to the ankle.”). In addition to suggesting that the tongue is a component distinct from the upper, the claim language indicates that the integral knit tongue extends through a throat area.

    “claim language does not specify it, both parties contend that the “portion of the knitted component” constitutes the majority of the upper. See Pet. 25– 26, 30 (Petitioner applying in this ground that which it characterizes as Patent Owner’s claim construction position); Prelim. Resp. 43 (Patent Owner noting that the Specification states that “a majority of upper 120 is formed from a knitted component 130,” and contending that limitation 1a1 means that “a majority of the upper must be knitted.” (quoting Ex. 1001, 6:57–59)). Nevertheless, we determine for the following reasons that Petitioner has not shown sufficiently that central textile element 60 of Dua-956 defines an upper within the meaning of the claims. See Pet. 26. Petitioner contends that, “[w]ith respect to what defines the upper, the ’636 patent discloses that the ‘upper generally extends over the instep and toe areas of the foot, along the medial and lateral sides of the foot, under the foot, and around the heel area of the foot.’” Pet. 27 (citing Ex. 1001, 1:44–46, 6:66–67). Petitioner reasons that, “[a]s such, the ’636 patent describes the upper as extending around six parts of the foot: (1) the instep area, (2) the toe area, (3) the medial side, (4) the lateral side, (5) under the foot, and (6) the heel area.” Id. Applying this reasoning to the reference, Petitioner contends that, “[o]f the six upper parts identified in the ’636 patent, only two of them—the medial and lateral sides—are not formed by the central textile element 60,” and therefor “the majority of the parts of the upper are formed by the central element 60.” Id. at 30 (citing Ex. 1002 ¶¶ 103–109). Petitioner provides an annotated versions of Figures 8B and 8C of Dua-956, reproduced below, to depict its contentions. Id. at 30. Above are Figures 8B and 8C of Dua-956—which are, respectively, perspective views depicting a second step and a third step in assembling the article of footwear (Ex. 1029, 3:41–45)—with central textile element 60 shaded green. As Petitioner concedes (Pet. 30) and as the annotated figures above show, central textile element 60 does not form the medial and lateral sides of the footwear. Thus, even if central textile element 60 constitutes the majority of parts of the upper, the sides of the upper remain undefined by the central textile element. Petitioner does not explain adequately how the upper is defined when the side components are missing. We determine that Petitioner has not demonstrated adequately for institution that Dua-956 discloses “a portion of the knitted component defining the upper,” as recited in independent claim 1.” slip op. at 20

    “Petitioner contends that “both upper 70 and 30' are constructed as a single, unitary knit element that defines the upper, and it would have been obvious to construct upper 30 in the same manner.” Pet. 65. Petitioner next turns to Horii, asserting that “Horii discloses “shoes 1 that are characterized by the fact that the entire upper is constructed of a single piece of upper member 2 that is made through weft knitting or circular knitting.’” Id. at 67 (citing Ex. 1017, 9) (emphasis omitted). Petitioner reasons that “[a] POSITA would have been motivated to manufacture Dua-956’s upper 30, for example, using the multilayer, single fabric of Horii because Horii’s single-piece knit upper would have provided upper 30 with a seamless structure.” Id. at 68. We disagree with Petitioner’s assertion that “[c]onstructing Dua-956’s upper 30 as a single, unitary knit component would not materially change the analysis under Ground 1A.” Pet. 70. In Ground 1A, Petitioner contends that “‘forward portion 61’ of the central textile element 60 is an integral knit tongue that extends through a throat area of the knitted component in the assembled upper 30.” Id. at 34. During the assembly of footwear 10, forward portion 61 is flipped over the top of the footwear and the separate textile elements 40 and 50 (the sides of the footwear) are stitched to the lateral and medial edges (64a and 64b) of forward portion 61—the purported tongue. See Ex. 1029, 9:5–11, Figs. 8B, 8C. Petitioner does not explain adequately how, when modifying the embodiment used in Ground 1A to have a seamless top portion, the purported integral knit tongue is retained in that combination. See Pet. 70 (Petitioner asserting that the proposed combination would still have an exterior surface, an inner surface, lace elements 33, channels 44/54, and loops 35, “along with the other structures identified under Ground 1A,” but not specifically discussing the purported integral knit tongue.).

Second, Petitioner does not explain adequately why a person of ordinary skill in the art would discern, even with Petitioner’s added red ovals, a tongue distinct from the upper and tongue extending through the throat area. We also do not find persuasive Petitioner’s contentions regarding differing textures. See Pet. 32–33. Even if differing textures could rise to the level of distinguishing an integral knit tongue from the upper, the purported tongue texture 48" is not confined to the area identified by Petitioner as the tongue. See Pet. 31 (annotated Figure 11, reproduced above). For example, texture 48" outside of Petitioner’s oval appears to wrap approximately halfway around the ankle opening, which is not argued to be consistent with an ordinary artisan’s understanding of a tongue. Or, put another way, there is no indication that the portion of the 48" texture within Petitioner’s red oval, which purportedly represents the tongue, is distinguishable from the remaining portion of the 48" texture outside of the red oval. We are not persuaded that Petitioner has demonstrated a reasonable likelihood of proving that a person of ordinary skill in the art would consider the relatively large area depicted as having texture 48" to be an “integral knit tongue.” In light of the above, we determine that Petitioner has not demonstrated a reasonable likelihood of prevailing on its challenge to independent claim 1 and its dependent claims 2–4 as anticipated by Dua-592.” slip op. at 23

Ex. 2002 ¶ 172; see also id. at ¶ 31 (Cantor “does not relate to the [spatial] analysis of tissue samples . . . .”). “[O]bviousness 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.” Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015). Here, Cantor fails to teach or suggest capture probes distributed randomly on a substrate comprising a nucleic acid sequence that identifies a unique location on the substrate as required by the challenged claims, and Petitioner fails to adequately articulate why a person of ordinary skill in the art would have modified Cantor to make the recited capture probes. In view of the above, we find that, on this record, Petitioner has failed to establish that Cantor teaches or suggests each element of the challenged claims. Accordingly, we determine that Petitioner has not demonstrated a reasonable likelihood of prevailing on its challenge that any of claims 1, 3, 6, 10, 11, 16, 18, 21, 24–26, and 30 would have been obvious over Cantor.” slip op. at 20
