      “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.

      “Carrying Out the Invention section, that “[t]he Factor C of the present invention is a Factor C derived from a horseshoe crab,” and states later in the same section that “[e]xamples of the horseshoe crab include . . . Limulus polyphemus.” Ex. 1006, 40. However, none of the remaining portions of ’767 application cited by Patent Owner relate directly to L. polyphemus; instead, the remaining portions of ’767 application cited by Patent Owner are directed to other species, in particular the Japanese horseshoe crab T. tridentatus. Further, Patent Owner’s witness, Dr. Schaefer, conceded that the ’767 application does not contain Factor C sequence information for L. polyphemus. See, e.g., Ex. 1067, 44:25–45:23. Although “[n]o length requirement exists for a disclosure to adequately describe an invention,” Falko-Gunter, 448 F.3d at 1365–1366, we are persuaded that a POSA would not, based on the totality of the above disclosures, reasonably understand that the inventors were in possession of the claimed HEK-293 recombinant L. polyphemus Factor C protein, in view of the state of the art as of December 10, 2013. In this regard, we note that adequate written description of a biological molecule, such as a HEK293 recombinant L. polyphemus Factor C protein, requires “more than a mere statement that it is part of the invention and reference to a potential method for isolating it”; instead, what is required is “‘a precise definition, such as by structure, formula, chemical name, or physical properties,’ not a mere wish or plan for obtaining the claimed chemical invention.” The Regents of the” slip op. at 21

      “Pfizer, Inc. v. Apotex, Inc., 480 F.3d 1348, 1364 (Fed. Cir. 2007). 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

      “At the outset, we agree with Patent Owner that the Specification purports to define “major peaks” in the following sentence: “The ‘major peaks’ herein refer to peaks higher than the average of the peaks in the result.” Ex. 1001, 13:28–29. We determine that this language satisfies at least two of the criteria set forth in Alnylam. Specifically, the sentence at “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. See Bell Atlantic, 262 F.3d at 1268 (“[T]he intrinsic evidence must ‘clearly set forth’ or ‘clearly redefine’ a claim term so as to put one reasonably skilled in the art on notice that the patentee intended to so redefine the claim term.”). Importantly, the Specification does not treat the existence of minor peaks as prerequisites for the existence of major peaks. Indeed, the Specification does not discuss “minor peaks” at all. See generally Ex. 1001. Likewise, none of the claims of the ’227 patent, whether challenged or unchallenged, recites “minor peaks” or any additional peaks beyond the disputed “major peaks.” Id. at 23:30–24:42. Nor does the Specification include an example of FFT analysis results in which the average of the peaks therein is calculated and those higher than the average are identified as major peaks.8” slip op. at 9

      “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. Petitioner has failed to prove, by a preponderance of the evidence, that claim 2 would have been obvious over Huang2 and Kuo.” slip op. at 42

      “A patentee “may choose to be his own lexicographer and use terms in a manner other than their ordinary meaning, as long as the special definition of the term is clearly stated in the patent specification or file history.” Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996) (citing Hoechst Celanese Corp. v. BP Chemicals Ltd., 78 F.3d 1575, 1578 (Fed. Cir. 1996)); see Markman v. Westview Instruments, Inc., 52 F.3d 967, 980 (Fed.

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. Alnylam Pharms., Inc. v. Moderna, Inc., 138 F.4th 1326, 1333 (Fed. Cir. 2025) (alteration in original). At the outset, we agree with Patent Owner that the Specification purports to define “major peaks” in the following sentence: “The ‘major peaks’ herein refer to peaks higher than the average of the peaks in the result.” Ex. 1001, 13:6–7. 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. See Bell Atlantic, 262 F.3d at 1268 (“[T]he intrinsic evidence must ‘clearly set forth’ or ‘clearly redefine’ a claim term so as to put one reasonably skilled in the art on notice that the patentee intended to so redefine the claim term.”).” slip op. at 8

      “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. Based on the totality of the evidence before us, we do not construe the claims to require non-major peaks.” slip op. at 16

      “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

We need not resolve this claim construction issue in order to resolve the parties’ disputes about the asserted ground of unpatentability.

      “We agree with Patent Owner that claim 15 requires modifying the first instruction set before determining the modified first instruction set based on an at least partial match between the new digital picture and the first digital picture. Claim 15 recites “modifying: the first one or more instruction sets” and “determining the modified the first one or more instruction sets . . . based on the at least partial match between the new one or more digital pictures and the first one or more digital pictures.” Ex. 1001, 162:65–163:15 (emphasis added). The phrase “the modified . . . instruction sets” in the determining limitation indicates an order because it refers back to the instruction sets modified in the modifying limitation. Id. Further, the phrase “based on the at least partial match” indicates that a partial match between the new picture and the first picture returns the modified first instruction set. Id. In order for a partial match to return the modified first instruction set, it is logical that the first instruction set previously was modified and correlated to the first picture. Id. Thus, claim 15 indicates that the modifying limitation is performed before the determining limitation. See Altiris, Inc. v. Symantec Corp., 318 F.3d 1363, 1369 (Fed. Cir. 2003) (“First, we look to the claim language to determine if, as a matter of logic or grammar, [the recited steps] must be performed in the order written.”).” slip op. at 8

More education can supplement practical experience and vice versa.” Pet. 4–5 (citing Ex. 1002 ¶¶ 17–18). Patent Owner does not dispute Petitioner’s assessment of the level of ordinary skill. PO Resp. 6. Determining the level of ordinary skill in the art involves various factors, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

Based on the complete trial record, we adopt the assessment offered by Petitioner and undisputed by Patent Owner, as it is consistent with the ’105 patent and the asserted prior art.” slip op. at 7

      “the term, and invited further briefing. Dec. on Inst. 14–15. Patent Owner does not assert that this construction affects Petitioner’s “first way” obviousness assertions. PO Resp. 31. After consideration of the post- Institution briefing, we agree with Patent Owner that Petitioner’s “second way” obviousness assertions rely upon a lack of ordering in claims 1 and 2 such that the transmitting of pre-call information may occur prior to the receiving on an incoming call (Pet. Reply 3); therefore, the term “pre-call information” requires construction to resolve the controversy. The “general rule [is that], ‘[u]nless the steps of a method [claim] actually recite an order, the steps are not ordinarily construed to require one.’” Mformation Techs., Inc. v. Research In Motion Ltd., 764 F.3d 1392, 1398 (Fed. Cir. 2014). As discussed above, we do not find the asserted information having a bridge number be transmitted after a call to a secondary number is made. The plain language of the claim requires that the pre-call information include a bridge number “for connecting the handset to the incoming call at the switch”; i.e., information to be used with respect to the incoming call recited in limitation [1.d]. The transmission of the pre-call information may therefore be at any time such that its contents (the bridge number) may be used with respect to the recited incoming call. Consequently, we do not adopt Patent Owner’s proffered construction.” slip op. at 13

      “whether teachings other than Winbladh would be preferentially considered, improperly frame the obviousness question. Patent Owner and Dr. Akl emphasize that Winbladh uses a “‘host resource’ that manages multiple call legs,” arguing that is different from Backhaus’s “more limited” system that uses a “conventional call routing system.” PO Resp. 36–37 (citing Ex. 2010 ¶ 113). However, the obviousness question is “whether the relevant artisan would be motivated to make the combination to arrive at the claims’ actual limitations,” not whether such a combination would preserve all aspects of either Backhaus or Winbladh. See Axionics, Inc. v. Medtronic, Inc., 2023 WL 4410686 (Fed. Cir. July 10, 2023). Moreover, “it’s not necessary to show that a combination is ‘the best option, only that it be a suitable option.” Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 800 (Fed. Cir. 2021) (quoting PAR Pharm., Inc. v. TWI Pharms, Inc., 773 F.3d 1186, 1197–98 (Fed. Cir. 2014)). Further, “[t]he test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference [but rather] what the combined teachings of those references would have suggested to those of ordinary skill in the art.” Facebook, Inc. v. Windy City Innovations, LLC, 973 F.3d 1321, 1343 (Fed. Cir. 2020) (“KSR does not support [the] theory that a person of ordinary skill can only perform combinations of a puzzle element A with a perfectly fitting puzzle element B”). Here, Petitioner’s combination provides for a pre-call transmission of local telephone number #βr, and would logically provide advantage in those situations in which a long distance number was originally used for the connection; i.e., those situations for which Winbladh is purposed. We further note that a combination need not work in all situations for a person having ordinary skill in the art to find it advantageous.

      “challenged claims to resolve the underlying controversy.” Pet. 8. Patent Owner proposes construing the term “channel” in all challenged claims to refer to “[a] channel [that] does not have to be fully connected on both ends or actually transmitting a particular type of information to qualify as a channel.” PO Resp. 6. Petitioner asserts that Backhaus teaches transmitting an access telephone number via a data channel in two ways. Pet. 22–26. As will be evident from our analysis below, we rely only on the “second way” for purposes of this Decision. Patent Owner’s proposed construction of the term “channel” does not impact the parties’ dispute about the “second way” that Backhaus teaches transmitting an access telephone number via a data channel. PO Resp. 21–22; Pet. Reply 3 (“Flyp does not even allege that its construction is relevant to the ‘second way’ the Petition addresses limitation [1.b].”); PO Sur-reply 11; Tr. 10:2–11, 68:3–24.5 Therefore, we determine that the term “channel” does not require an express construction to resolve the parties’ disputes regarding the asserted grounds of unpatentability. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

      “suggest that we categorially disregard Dr. Lin’s declaration. As a general point, our precedential decision in Xerox does not provide a blank condemnation of declaration testimony that is identical or virtually identical to language in a paper. Xerox found that the “cited declaration testimony is conclusory and unsupported, adds little to the conclusory assertion for which it is offered to support, and is entitled to little weight.” Xerox at 15; see also 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”). Here, Dr. Lin cites to evidence to support certain testimony. See, e.g., Ex. 1003 ¶ 73 (citing to Ex. 1007 and Ex. 1011). Also, we do not rely on the Lin Declaration as evidence of any legal standard or for Dr. Lin’s legal conclusions. Rather, we rely on the Lin Declaration to support our factual determinations regarding the teachings of Backhaus, Saksena, and Taylor, as well as why and how a person of ordinary skill in the art would have combined those teachings. Finally, Patent Owner’s arguments go to the weight of Dr. Lin’s testimony. We assess the appropriate weight to give the testimony in our analyses below.” slip op. at 15

      “provided a motivation to combine the teachings of a PSTN interface in Backhaus’s system, even though Backhaus discloses interfacing with the PSTN. Backhaus is silent as to how its system interfaces with the PSTN. As such, we agree with Petition that a person having ordinary skill in the art would have been motivated to connect SLS platform 115 with the PSTN and to also include a PSTN interface in order to facilitate such an connection when implementing Backhaus’s system and processes—such that SLS platform 115 could provide the disclosed second line services to many device users connected to the PSTN that is known to provide reliable communications. Pet. 50. Indeed, Patent Owner’s argument that Backhaus discloses interacting with the PSTN strengthens Petitioner’s position, demonstrating that a person having ordinary skill in the art, when considering Backhaus’s and Taylor’s teachings together, would have used a PSTN interface to ensure a connection with a PSTN. Cf. Pet.

See Inst. Dec. 17–18. We continue to be persuaded that one of ordinary skill in the art would have consulted and utilized disclosures in the RFC references to understand and implement the protocols disclosed by Foti. We are further persuaded by Petitioner’s arguments that such skilled artisans would have had a rationale to combine the teachings of Wright and Lloyd with those of Foti for the reasons provided. Petitioner has asserted that each of the supporting references would have been used by persons of ordinary skill in the art to modify or enhance the system described in Foti for the benefits described for the proposed changes.
