    “Petitioner’s proposed POSA definition lacks specificity. That definition, if interpreted generically, could mean that a person may qualify as a POSA if they had, for example, a B.S. in mechanical engineering and only two years of experience designing any type of product in any field. That is too broad. We find that a POSA would have had the agreed-upon educational credentials—an undergraduate degree in mechanical engineering or a related engineering discipline. Ex. 1003 ¶ 35; Ex. 2033 ¶ 61. We find that a POSA would also have had 2–4 years of design or engineering experience related to products in the field of the invention, which involves endovascular devices and the surgical procedures that use such devices. Ex. 1001, 1:16–54 (background of the invention). Such devices include, but are not limited to, hemostasis valves and catheters for testimony of the parties’ experts, the POSA need not have had first-hand experience designing hemostasis valves. See, e.g., Ex. 1037 (Zalesky Tr.), 72:11–73:7 (testifying direct experience “designing” hemostasis valves or aspiration catheters is not necessary, but “general experience with vascular devices and procedures” is required). Further, as Dr. Zalesky testified, the POSA’s experience related to developing such devices “could be as simple as bench testing and looking at clinical data.” Id. at 74:5–75:1. Lastly, a POSA would have understood such devices’ design requirements as determined by the needs of the physician, patient, and procedure, which understanding may be informed by work experience or study.

    “Patent Owner cites intrinsic evidence in support of its interpretation, which include claim 1’s recitation of an “active tensioning mechanism” comprising the filament and the Specification’s description of a filament that can be both “loosened” and “tightened.” PO Resp. 14–17 (citing, e.g., Ex. 1001, 9:36–37, 9:53–56 (teaching “the filament 150 is tightened” when the actuator buttons are released and “the filament 150 is loosened” when the buttons are pressed to open the valve)); see also Ex. 2025, 1288 (defining “tension” as to “tighten to a desired or appropriate degree”). These descriptions from the patent are more consistent with the view that the filament is characteristically flexible, not rigid. 10 We reached the same conclusion, based on substantially the same records, in the Institution Decision and the Final Written Decisions in the 1157, 156, and 289 IPRs. Inst.

After we construed the “filament” term to require flexibility at institution, Petitioner provided no further argument or evidence on this issue in its authorized trial briefing or at oral hearing. See generally Pet. Reply. embodiments (where the filament forms one or more loops like depicted and described in Figures 6–7) require a flexible structure. See, e.g., Ex. 2032, 15–16 (explaining that the device would not work to constrict the tubular sidewall and lumen (analogous to the elongate member defining a lumen of the claims here) if the filament forming the loop(s) was inflexible); Ex. 1001, Figs. 6–7 (filament 150, with sub-filaments 150-A and 150-B). Although flexibility of the filament in the patent’s “bight” embodiments (e.g., as shown in Figures 8 and 9) is less clear, there is a dearth of evidence from Petitioner—either intrinsic or extrinsic to the patent—showing why a POSA would have understood the bights as embracing rigid structures. See Ex. 1001, Figs. 8–9. Moreover, as admitted by Petitioner’s expert, that a filament may be made from various materials described in the patent (e.g., synthetics or metals) does not, absent more information, lead to a conclusion that a filament is “rigid.” Ex. 2030, 125:2–126:4 (testifying “the relative stiffness or rigidity is not clear from those . . . materials without knowing much more information”).” slip op. at 16

    “Network LLC, 929 F.3d 1350, 1357 (Fed. Cir. 2019). At first glance, the language of the limitation at issue—which, again, recites “the compressed air and the operative fluid mix together in said mixing chamber to form the fluid dispersion”—would seem to require the “fluid dispersion” (under the stipulated construction) to be fully formed in the “mixing chamber.” In other words, the language of the limitation alone would seem to support Patent Owner’s proposed construction for the “form the fluid dispersion” limitation. But the claim construction analysis does not end with consideration of the claim language alone. Next, we turn to the Specification. The Federal Circuit has said that the specification “is the single best guide to the meaning of a disputed term.” Phillips, 415 F.3d at 1315 (quoting Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996)). Here, the discussion in the Specification of precisely the same language as in the limitation at issue strongly supports that “to form a fluid dispersion” in the limitation at issue requires only initial mixing of the compressed air and operative fluid in the mixing chamber, with further “formation” of the ”fluid dispersion” occurring downstream of the mixing chamber: More importantly, the “predetermined amount” of compressed air and the “preselected amount” of the operable fluid are initially mixed together in the mixing chamber 226 to form a fluid dispersion. The diffusion chamber 112" is further structured to facilitate the formation of a plurality of substantially uniform droplets, as defined hereinabove, in the fluid dispersion prior to discharge from the diffusion chamber 112" through discharge port 132. Ex. 1001, 10:62–11:2 (emphasis added) (discussing Figure 6), quoted, in part, at Pet. Reply 6–710; see also Ex. 1001, 5:64–6:4 (same language, except without double primes, in a discussion of Figures 1 and 2). To be sure, certain passages in the Specification could be read to indicate that a “fluid dispersion” must be fully formed in the “mixing chamber.” See, e.g., Ex. 1001, 6:11–12 (“More in particular, the suppression chamber 232 receives the fluid dispersion from the mixing chamber 226.”); see also id. at 7:22–33, 11:39–52 (both implying that a “fluid dispersion” is formed in the mixing chamber).

    “To satisfy its burden of proving obviousness, a petitioner cannot employ mere conclusory statements. The petitioner must instead articulate specific reasoning, based on evidence of record, to support the legal conclusion of obviousness.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1380 (Fed.

Based on the complete record, we agree with Patent Owner that “Petitioner’s asserted motivation boils down to the conclusory statement that given Goubet and Kaiser, ‘it was well known in the field at the time of the invention that droplets of greater uniformity result in uniform droplet evaporation.’” PO Resp. 31 (quoting Pet. 59). We agree with Patent Owner that Petitioner’s discussion of the alleged reasons to combine (Pet. 59) is insufficient to support the proposed combination here. See Magnum Oil, 829 F.3d at 1380. Specifically, we are not persuaded that Kaiser’s teachings—which relate to combustion (Ex. 1014 at 43)—would have led one of ordinary skill in the art to the proposed modifications, which would allegedly “improve the smoothness (i.e., less harsh) of the aroma generated as the oil droplets evaporate in the surrounding airspace.” See Pet. 59 (emphasis added); White Pet. Decl. ¶ 251 (same); see PO Resp. 32 (“Rather, Dr. White merely describes the ability to achieve the effect as in the claimed patent, not why a [person of ordinary skill in the art] would look to the field of electrospray injection and combustion in mesoscale power-generation systems, using high-voltage electric fields to generate charged fuel droplets for controlled combustion in catalytic micro-combustors when considering atomization for scents.”). For these reasons, we determine, in light of the complete record, that Petitioner has not shown by a preponderance of the evidence that one of ordinary skill in the art at the time of the invention would have had reason to combine Goubet and Kaiser, as proposed. slip op. at 32

    “We disagree with Patent Owner that a person of ordinary skill in the art would have understood that limitation 1.2 must be performed before limitations 1.3 or 1.4. See Ex. 1001, 35:21–24. See Interactive Gift Exp., Inc. v. Compuserve Inc., 256 F.3d 1323, 1342 (Fed. Cir. 2001) (“Unless the steps of a method actually recite an order, the steps are not ordinarily construed to require one.” (citing Loral Fairchild Corp. v. Sony Corp., 181 F.3d 1313, 1322 (Fed. Cir. 1999)). The evidence suggests that a “target printer” is any printer that is ultimately selected for fabricating the object, and such a printer could send its configuration information either before or after that determination is made in limitation 1.2. This interpretation does not render the word “target” meaningless. At some point, a printer must be determined to be the target printer, which is the one intended to ultimately fabricate the three-dimensional object. But the target printer still exists, and is capable of being queried, before that determination is made. We find the examples in the ’774 patent pertinent to this question. The ’774 patent states that “the target printer may include more than one printer.” Ex. 1001, 18:66–67. In discussing the step of “query target printer for properties 306” (Fig. 3A), the ’774 patent states that “[i]n one aspect, numerous queries are sent to numerous printers, e.g., for use in selecting one or more of the printers as the target printer.” Id. at 19:8–10. Alternatively, “the query is sent to a printer that is not necessarily the target printer as described herein, e.g., when the query or information received from a response to the query is used for the selection of the target printer.” Id. at 19:11–14. Importantly, the second embodiment states that the queried printer “is not necessarily the target printer,” suggesting that the queried printer could be the target printer even before it is determined to be such. Id. at 19:11–12 (emphasis added). Based on the evidence of record, a person of ordinary skill in the art would have understood that the “target printer” can be determined after the query recited in limitation 1.3 or the reception of configuration information recited in limitation 1.4. Thus, the evidence does not impose an ordering between limitations 1.2 and 1.3 or between limitations 1.2 and 1.4. The evidence also does not support Patent Owner’s argument that the two reverse-order examples in the ’774 patent are unclaimed embodiments.” slip op. at 10

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

    “1. Motivation to Combine Becerra and Couckuyt Petitioner argues that a person of ordinary skill in the art would have been motivated to combine the teachings of Becerra and Couckuyt because such a person would have recognized that Couckuyt discloses useful techniques of assigning data to Becerra’s charts, including assigning data to each axis. Pet. 34 (citing Ex. 1005 ¶¶ 19, 52, Fig. 5; Ex. 1003 ¶ 224). Petitioner contends that Couckuyt discloses associating data from a “spreadsheet document” with a chart, such as a “bar graph.” Id. at 35 (citing Ex. 1006, 6:1–37; Figs. 3a, 3c). below. Petitioner’s annotations to Figure 4 identify “Drop Zones” in red and “Data Fields” in Blue. Id. at 36. Petitioner contends Couckuyt discloses a “drag-and-drop user interface (DDUI) . . . associated with a data source, such as the two-dimensional data source 300,” and Figure 4 illustrates the DDUI permitting “value data fields and the characteristic data fields . . . to be dragged and dropped into drop zones.” Id. at 35–36 (citing Ex. 1006, 7:10–13). Petitioner contends that a “primary benefit of the charting DDUI is that the user can quickly change the data that is being presented in the chart,” and using Couckuyt’s techniques, a user can “quickly change the data” and see the desired effects. Id. at 36 (citing Ex. 1006, 1:18–19; Ex. 1003 ¶ 228). Petitioner contends that when Becerra’s control panel includes multiple charts, Couckuyt’s techniques would allow dragging-anddropping data from a data source to multiple charts, and would simplify the process of assigning data to multiple control panel components. Id. at 36–37 skill in the art would have also had a reasonable expectation of success combining Becerra with Couckuyt because the combination would amount to nothing more than incorporating Couckuyt’s well-known drag-and-drop techniques into Becerra’s system. Id. at 37 (citing Ex. 1003 ¶¶ 229–231). Patent Owner responds that Couckuyt focuses on selecting a data icon that corresponds to dragging and dropping data fields, not dragging and dropping data, while Becerra teaches that selecting various data ranges from the spreadsheet is desirable. PO Resp. 36–37 (citing Ex. 1004 7:48–52; Ex. 2001 ¶ 146). According to Patent Owner, a person of ordinary skill in the art would not have been motivated to merely select data fields that do not limit the selected data in any way. Id. Patent Owner further argues Becerra’s method of binding components to a spreadsheet range and extracting formulas from a spreadsheet teaches away from the multiple chart generation scheme of Couckuyt that uses drag and dropping of data fields. Id. at 37. According to Patent Owner, Couckuyt is directed to the need for a charting DDUI that can generate multiple charts at the same time and such a need does not exist in Becerra which in turn is focused on creating a control panel that is an interactive graphics simulation. Id. (citing Ex. 1004, 1:66–67, 2:5–8; Ex. 1005 ¶ 11; Ex. 2001 ¶ 148). Based on our review of the complete record, we determine that” slip op. at 31

    “We find that Petitioner establishes by a preponderance of the evidence that Choulis anticipates claim 13. We agree with Petitioner, in that regard, that Choulis explicitly teaches “using spin-coating as a method for depositing materials, which involves a simultaneous application process” as required by claim 13. Reply 16 (citing Pet. 40–41; Ex. 1044 ¶ 45).16 We 15 Petitioner raises Djobo as a background reference supporting that Choulis anticipates deposition of PVK by evaporation. Pet. 41. Patent Owner counters that Djobo, to the contrary, shows that Choulis does not teach deposition of PVK by evaporation. Resp. 48. In other words, both parties cite Djobo in connection with the ground based on anticipation by Choulis. Against that backdrop, we determine that Patent Owner waives any argument that Petitioner improperly cites Djobo as a background reference in support of the anticipation challenge, which is based on Choulis alone. Resp. 48 (nowhere asserting that the challenge is deficient on that basis). That waiver arises because no argument, in that regard, is raised in Patent Owner’s Response see Inst. Dec. 34 (“The Board shall deemed waived any issue not raised by Patent Owner in a timely response to the Petition . . . .”). 16 Patent Owner’s statement that “spin coating tends to cause phase separation” is not developed adequately on this record and, therefore, is further agree with Petitioner that Patent Owner “has not contested this point.” Resp. 48. “Therefore, there is no genuine dispute regarding the unpatentability of claim 13,” although Patent Owner raises “arguments concerning evaporation, which is a distinct process from spin-coating” relevant to the additional limitations of claim 14. Reply 16. We determine that Petitioner establishes by a preponderance of the evidence that Choulis anticipates claim 13. Patent Owner, however, has the better position on whether Choulis anticipates claim 14, which “includes the requirement of applying matrix materials via evaporation coating.” Reply 16. Petitioner seems to abandon that challenge in the Reply by raising arguments that appear, on this record, to bear exclusively on whether the subject matter of claim 14 would have been obvious over Choulis.17 Id. at 16–17. Those arguments are insufficient to counter Patent Owner’s reasons why Choulis does not anticipate the “evaporation coating” limitation of claim 14. Compare id., with Resp. 48. On this record, therefore, we determine that Petitioner does not establish by a preponderance of the evidence that Choulis anticipates claim 14. unpersuasive to persuade us “that Choulis does not have three matrix materials.” Sur-reply 15. That argument runs counter to Choulis’s explicit, intrinsic disclosures, which illustrate (Ex. 1004, Fig. 4) and describe (id. ¶ 30) an organic light emitting layer composed of three matrix materials. See Pet. 24–25 (citing Ex. 1004, Fig. 4, ¶ 30); see also Ex. 1003 ¶¶ 85–88 (persuasive declaration testimony of Dr. Holmes, cited at Pet. 24–25). 17 There is some confusion on this point, given that both parties sometimes collapse, into a single argument, whether Choulis anticipates or renders obvious claim 1.

    “On this record, therefore, we determine that Choulis, at minimum, suggests that a person of ordinary skill in the art at the time of the invention would have recognized PMMA as a suitable alternative to PVK in Choulis’s Figure 4 embodiment, notwithstanding any differences raised by Patent Owner. Ex. 1004 ¶ 44. Patent Owner’s argument that no disclosure in Choulis suggests that an ordinarily skilled artisan “would have found it desirable to use PMMA in place of PVK in Choulis’s devices” misses the mark, where Choulis includes both PMMA and PVK in lists of materials suitable for use as host or matrix materials. Resp. 38; Ex. 1004 ¶ 44. “Our caselaw is clear. It’s not necessary to show that a combination is ‘the best option, only that it is a suitable option.’” Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 800 (Fed. Cir. 2021). Even if Choulis does not expressly disclose substituting PMMA for PVK in the Figure 4 embodiment, “an ordinarily skilled artisan would have found it obvious to make that substitution.” Reply 10 (citing Pet. 31 (citing Ex. 1003 ¶ 100; Ex. 1044 ¶ 23)). The suggestion for that substitution is set forth unambiguously in Choulis’s listing of both “PVK” and “PMMA” as materials suitable for use as a first “host” material in Choulis’s organic functional layer; that is, “the light emitting layer” that is “described above” in Figure 4. Ex. 1004 ¶ 44. ii. Alternative Reasoning for Replacing PVK with PMMA Patent Owner counterargues that using PPMA in place of PVK would have been understood to “upset the hole and electron balance,” as well as “affect hole-charge recombination,” and “degrade the performance of the resulting OLED system.” Resp. 37. Petitioner responds with evidence that “it would have been a routine task for” an ordinarily skilled artisan “to optimize the composition of each component within the light-emitting layer to achieve the desired charge balance.” Reply 11 (citing Ex. 1004 ¶ 24). Petitioner’s response brings to light a second reason why an ordinarily” slip op. at 40
