      “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

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

      “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

    • Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed board ownDecided for patent owner

      “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. Cir. 1995) (en banc) (“[A]ny special definition given to a word must be clearly defined in the specification.”), aff'd, 517 U.S. 370 (1996); CCS Fitness, Inc. v. Brunswick Corp., 288 F.3d 1359, 1366 (Fed. Cir. 2002). “[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.” Bell Atlantic Network Services, Inc. v. 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

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

      “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

Patent Owner contrasts this with the scope of the claims of the ’391 patent and contends that the challenged claims are directed to “the underlying composition itself, where the enteric material is an ingredient of the composition combined with the endoxifen.” Id. To support its contentions, Patent Owner attempts to apply the doctrine of claim differentiation across patents, noting that [t]he related ’334 describes a composition where the enteric requirement is not part of the composition, reciting “[a]n oral formulation comprising an endoxifen composition encapsulated in an enteric capsule.” EX2014, cl.1.

      “distinguish the preamble language reciting “[a] composition comprising an endoxifen and an enteric material” from Ahmad. Prelim. Resp. 13–16. Specifically, Patent Owner contends that Petitioner’s arguments rely on Ahmad’s alleged disclosure of endoxifen encapsulated in enteric-coated capsules. Id. at 14. For example, Patent Owner contends that “every portion of Ahmad relied upon by Petitioner describes a ‘composition containing endoxifen’ that can then be coated with a separate external ‘enteric coating.’” Id. at 15. Patent Owner further contends that these disclosures fail to disclose an enteric material that is a component (with endoxifen) of the composition itself. At most, these disclosures purport to describe (1) a pharmaceutical composition of endoxifen (2) encapsulating the finished composition in a separate external enteric coating. See EX1003, 18:27-29 (“Enteric coating of capsules filled with composition art.”). Prelim. Resp. 15. Patent Owner therefore concludes that “Petitioner identifies no teaching in Ahmad that the enteric material is a component of the endoxifen composition, as claimed.” Id. at 16. Based on our preliminary construction of the term, “[a] composition comprising an endoxifen and an enteric material” discussed above, and, having considered the arguments and evidence presented by the parties at this stage of the proceeding, summarized above, we find that Petitioner has shown it is more likely than not that Ahmad discloses each limitation of claims 1 and 32 for the reasons stated in the Petition, which we adopt for purposes of this Decision.

      “(“POSITA”) relevant to the ’223 patent “would be a Ph.D. student with a minimum of two years of experience in their faculty advisor’s laboratory” and would have an understanding of “electrospinning fibers, including for tissue engineering, tissue engineering techniques, and using/performing FFT analysis.” Pet. 18–19 (citing Ex. 1003 §II.C). Patent Owner does not dispute this skill level. Prelim. Resp. 10. At this stage of the proceeding and for purposes of our analysis in this Decision, we adopt Petitioner’s definition as that definition is consistent with the level of skill in the art reflected by the prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “Simpson’s testimony at this preliminary stage. Dr. Simpson extensively discusses the FFT methodology used in the Ayres papers (for which he is the senior author), and we find these papers provide sufficient underlying facts, data, and technical reasoning to support his opinion regarding the inherent symmetry of the FFT output image. Ex. 1003 ¶¶ 38–51. Contrary to Patent Owner’s argument, the fact that the Ayres 2008 paper uses the term “typically” does not undermine Dr. Simpson’s conclusion. Ex. 1010, 609. In context, it is clear that the refenced statement only speaks to how the data is typically reported rather than whether the result itself would only be typical. Indeed, the same sentence goes on to explain that the reason why the data is typically reported only for 0–180° is because “the frequency plot is symmetric.” Id. We are also not persuaded by Patent Owner’s argument that Ayres 2008 undermines Dr. Simpson’s testimony regarding “typical[] practice” because it presents FFT analysis results plotted to 360°. Rather than undermining his testimony, the plot shown in Figure 1F of Ayres 2008 further confirms the symmetrical nature of the FFT results for aligned fibers. Moreover, the fact that there are minor variations at the tips of the two peaks shown in Figure 1F does not undermine or contradict the conclusion that the major peaks for aligned fibers will necessarily be about 180° apart. The challenged claims do not require a perfect repetition or identity of the major peaks in the FFT output plot. Additionally, Dr. Simpson’s own reproduced FFT analysis of the SEM image in Huang2’s Figure 1B using the methodologies described in the Ayres 2006 and Ayres 2008 papers, which shows major peaks at 90° and 270°, further confirms that the claimed FFT analysis result is an inherent feature of Huang2’s anisotropic fibers. Ex. 1003 ¶¶ 110–111. We do not find that Dr. Simpson’s testing violates 37 C.F.R. § 42.65(b), insofar as Dr. Simpson’s declaration sufficiently explains: (1) “why the test or data is being used”; (2) “how the test was performed and the data was generated”; (3) “how the data is used to determine a value”; (4) “how the test is regarded in the relevant art”; and (5) “any other information necessary for the Board to evaluate the test and data.” See Ex. 1003 ¶¶ 38–51 (explaining FFT methodology used by Dr. Simpson). Although Dr. Simpson’s declaration does not appear to spell out all the details of the particular protocol or the version of the ImageJ software he used, we find his explanation that he used the methodology described in Huang2 (which references the Ayres 2006 paper) and the ’223 patent (which references the Ayres 2008 paper) sufficient for purposes of institution. Even assuming there may be some differences in the specific FFT methodology used in the two Ayres papers, we do not find anything at this stage to indicate that any such differences would matter with regard to the claim requirement that the major peaks are about 180° apart, especially given that both papers confirm the symmetrical nature of the FFT output plot. Furthermore, while Patent Owner argues that Dr. Simpson does not account for certain aspects of the FFT analysis discussed in the Ayres 2006 and Ayres 2008 papers, there is no evidence at this stage that Dr. Simpson did not follow the protocol described in his own papers, or that he failed to account for any specific aspects that could make a meaningful difference with regard to the FFT analysis result.” slip op. at 25

      “We do not agree with Patent Owner that the quoted language of the ’999 patent requires a construction of the term “second link” that excludes any Bluetooth connection that reuses authentication information. Other than the one vaguely worded sentence in the ’999 patent, Patent Owner does not point to any supporting evidence for this interpretation. PO Resp. 25–26; Ex. 1001, 1:47–53). To the contrary, the evidence supports a finding that when two devices reestablish communication after being disconnected, the subsequent Bluetooth link is considered a different link. See Reply 18 (citing Ex. 1004, 151 (“Consequently, once a semi-permanent link key is defined, it may be used in the authentication of several subsequent connections between the Bluetooth units sharing it.”). This understanding is consistent with the ’999 patent, which refers to “initial Bluetooth link[s]” and “subsequent Bluetooth link[s]” (Ex. 1001, 1:49–50, 1:58, 4:40), and discloses that multiple links can be made between two Bluetooth compatible devices (id. at 1:17–20), without any clarification that such links are considered the same if authentication information is reused. Accordingly, we find that claim 13 requires two different links, one of which occurs later in time than the other, but that those links are not required to be of different types. And we do not agree with Patent Owner’s narrow reading, based on one sentence in the ’999 patent, that Bluetooth links that reuse authentication codes are considered the same link.” slip op. at 11

This is based on both the intrinsic evidence and extrinsic evidence, which support such a finding, and a lack of evidence in the record to the contrary.7 See Ex. 1003, 4:62–67 (“Each time the portable computer 50 is in local or direct communication with the desk top computer 48 . . . the identity of the portable computer 50 is authenticated by the desk top computer 48 by a suitable test such as a challenge/response routine as outlined below.”); Ex. 1004, 99, 108, 149–154, 169–178, 1043, 1045–1047, 1053; Ex. 1006 ¶¶ 96–123; Ex. 1013 ¶¶ 14–22. We are not persuaded by Patent Owner’s argument that BT Core teaches away from a very long, frequently changed, security key. See PO Resp. 19–20.

See In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994). To the contrary, the facts suggest that a person of ordinary skill would have understood Varadharajan to encourage the use of any known, robust, authentication scheme (see Ex. 1003, 4:62–67), and the record shows that a person of ordinary skill would have understood Bluetooth’s authentication mechanism to be such a scheme (see Ex. 1001, 1:11–59, 5:38–41; Ex. 1004, 151–152, 157; Ex. 1006 ¶¶ 100–109; Ex. 1013 ¶¶ 17– 21). Finally, we find Petitioner has sufficiently shown that a person of ordinary skill in the art would have had reason to attempt to use Bluetooth’s authentication mechanism over Varadharajan’s direct link because it was a well-known method of implementing robust short-range communication and doing so would have required only the simple substitution of Bluetooth for infrared, in a similar manner, to achieve predictable results.

Contrary to Petitioner’s and Mr. Prairie’s assertions, the proposed combination does not merely apply known techniques to a known device, because none of the cited references use brush belts and paddle wheels in the manner Petitioner proposes. As discussed in greater detail below, Benac teaches that a paddle wheel can be used to ensure that seeds jammed in vacuum holes are released reliably, and then dropped to the ground. Benac does not address brush belts as an endless member and, therefore, does not teach that paddle wheels can be used to guide seeds into the bristles of a brush belt, as Petitioner proposes.

      “Petitioner’s and Mr. Prairie’s analysis does not acknowledge, much less bridge, the gap between Koning’s use of a brush belt to hold potatoes from above as they lie on a conveying surface, versus the brush belt’s use in above.10 During his deposition, Mr. Prairie resisted agreeing that the potatoes are lying on the conveyor in Koning, testifying that he takes from Koning’s description that “they are captured within the belt with brush hairs. And that there is some weight that’s along the conveying member 23.” Ex. 2193, 96:24–99:25.

Mr. Prairie’s refusal to acknowledge the differences between the brush belt’s function in Koning versus the proposed combination undermines the credibility of his testimony that the proposed combination would have been a simple application of a known technique to a known device. 10 See WBIP, LLC v. Kohler Co., 829 F.3d 1317, 1327 (Fed. Cir. 2016) (noting expert testimony that supported the absence of a motivation to combine: “[I]f I can equate this one to kind of a simple analogy, if you’re trying to build a piece of furniture. What’s a typical thing? You put on a piece of wood. You take a nail, and you hit the nail with a hammer. In control terms, what Mr. Phipps is suggesting is that you put the hammer on the workbench, pick up the piece of furniture and bash the piece of furniture onto the hammer. It’s totally backwards from what I believe one of skill in the art would even attempt . . . .”). have been simple for an ordinarily skilled artisan to adapt Koning’s brush belt for use in the proposed combination, where seeds are deposited onto the brush belt from above—is further undermined by his testimony that he “can’t recall a time where I’ve seen a seed being dropped into a brush belt.” Ex. 2193, 113:5–9; see also Ex. 2263, 81:2–12 (“Q. And you never attempted to drop a seed onto a moving brush belt to see whether that would be inserted into the brush belt, correct? A. As I stated, for the purposes of this case, I did not do any physical experimentation with a moving brush belt as I didn’t feel it was necessary. The prior art discloses sufficient information.”) (objection omitted). Mr. Prairie has “had some industrial design projects where we’ve had to utilize brushes for various applications,” but he “ha[s] not used a brush belt to convey seed.” Ex. 2194, 297:6–16. Mr. Prairie testified that “prior to writing this declaration, brush belt technology was not a specific area that I study, that I was researching.” Ex. 2263, 79:6–9. Indeed, during his initial deposition in this case, the only specific example of a moving brush belt Mr. Prairie could recall seeing was Patent Owner’s ExactEmerge product. Ex. 2193, 108:6–110:10. The basis for Mr. Prairie’s opinion, that a seed would be expected to enter a moving brush belt in the proposed combination, appears to only be Koning itself. Ex. 1002 ¶¶ 79–81; Ex. 2193, 116:12–19, 118:7–23; Ex. 2263, 159:5–160:2. When asked at his deposition, Mr. Prairie did not explain any other engineering analysis he performed to make that determination. Ex. 2193, 114:23–117:12. Mr. Prairie testified that he “did not operate a brush belt for this declaration because [he] didn’t feel it was necessary to make my assessments” and he “did not do study or experimentation on a brush belt as I did not feel it was necessary.” unpersuasive because, as discussed above, Koning does not teach using a brush belt to receive and convey seeds that have been dropped onto it from above. Mr. Prairie does not account for that difference by explaining why an ordinarily skilled artisan would expect Koning’s brush belt to effectively capture and carry seeds dropped from above, as in the proposed combination.” slip op. at 26
