      “several threads, lines, cords, robes, ribbons, flat wires, sheets, or tapes. The Specification supports such interpretation. Ex. 1001, 9:21–23. Nevertheless, as Patent Owner argues, Petitioner’s interpretation is incomplete and does not address persuasively the dispute raised here— whether the “filament,” as recited in claim 1, requires flexibility. Based on the parties’ arguments at this preliminary stage, we agree with Patent Owner that flexibility is necessary. The claims, as understood by the POSA, suggest that the filament must be flexible. Claim 1 “recites that ‘the first filament [is] formed into a loop around the collapsible tubular sidewall” and that the “diameter of the valve lumen decreases in response to reducing a diameter of the loop.” See supra Section II.D. As Dr. Zalesky credibly explains “[t]o ‘reduc[e] a diameter of the loop,’ the filament must be ‘flexible’ because if it were rigid or inflexible the loop would retain the same diameter when acted on by the first actuator.” Ex. 2001 ¶ 58 (“This inherent property of flexibility is essential to the loop structure of the claims.”). We observed essentially the same principle in the related 1157 IPR for embodiments where the filament forms a “loop” around the collapsible tubular member, such as shown in Figure 6 of the patent. IPR2024-01157, Paper 7 at 16 (“Thus, in the above embodiment [(shown in Fig. 6)] a flexible filament is required (i.e., a the loop to constrict and seal the valve).”).11” slip op. at 15

Pet. 18–19. Patent Owner responds that whether the term “aspiration” limits claim 1 is “not germane to Patent Owner’s arguments here.” Prelim. Resp. 21.

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “At this stage, we find Petitioner’s description of the level of ordinary skill in the art to be sufficient. According to the ’360 patent, “[t]he field of the invention is related to sensor arrays for the detection and diagnosis of disease states.” Ex. 1001, 1:28–29. The Specification describes accomplishing such by analysis of protein coronas using techniques such as LC-MS/MS. See id. at 4:43–5:2 (describing Figure 1). The prior art cited by Petitioner also describes the analysis of protein coronas using similar analytical techniques. See, e.g., Ex. 1005, 584; Ex. 1007, 1870; Ex. 1008, 355–356. Accordingly, the present record supports that a POSA would have an understanding of both proteins and the analytical techniques, e.g., mass spectrometry, that can be used to characterize them. We understand Petitioner’s definition of a POSA to encompass these elements. It requires a formal degree in chemistry,5 which itself entails some knowledge of proteins and related analytical techniques, along with several years’ additional experience in proteomics, protein analysis, or mass spectrometry. Moreover, Petitioner’s definition is flexible in that it allows higher education or skill with, e.g., mass spectrometry, to make up for a lack of specific experience with proteomics assay and protein coronas. This explanation is reasonable and supported on the current record.” slip op. at 8

    • Expert testimonyPetitioner expert creditedDecided for petitioner

      “Third, and perhaps most importantly, there is “no requirement for perfect match between an expert’s experience and the relevant field.” See Consolidated Trial Practice Guide (Nov. 2019) 34, available at https://www.uspto.gov/sites/default/files/documents/tpgnov.pdf (“CTPG”). (citing SEB S.A. v. Montgomery Ward & Co., 594 F.3d 1360, 1373 (Fed. Cir. 2010)). A person need not be a person of ordinary skill in the art to testify as an expert under Federal Rule of Evidence 702, but rather must be “qualified in the pertinent art.” Sundance, Inc. v. DeMonte Fabricating Ltd., 550 F.3d 1356, 1363–64 (Fed. Cir. 2008). Here, there is no dispute that Dr. Vargas is qualified in the art of mass spectrometry and, on the current record, we discern no reason why she is not qualified to offer the testimony in her declaration. At most, Patent Owner’s argument that Dr. Vargas lacks experience “perform[ing] mass spectrometry techniques specifically for protein analysis,” goes to the weight we should afford her testimony at trial. See Prelim. Resp. 28–29. It is not a sufficient reason to deny institution, particularly given that Dr. Vargas’s testimony is only part of the showing offered in support of the Petition. 6 Patent Owner’s narrow characterization of Dr. Vargas’s experience (see Prelim. Resp. 28–29) is arguably inconsistent with the description in her CV (Ex. 1004). In any event, Patent Owner will have an opportunity to examine Dr. Vargas regarding her qualifications.” slip op. at 10

      “The Board regularly denies as moot motions to exclude evidence that is not relied upon in a final written decision. See, e.g., Foursquare Labs, Inc., v. BoardActive Corp., IPR2023-00919, Paper 29 at 84 (PTAB Nov. 27, 2024); Neurocrine Biosciences, Inc., v. Spruce Biosciences, Inc., PGR2021- 00088, Paper 64 at 12, 20, 21, 23 (PTAB Nov. 26, 2024). Patent Owner does not persuade us that a deviation from this general practice is warranted in this case––the reason given by Patent Owner, involving concerns stemming from appellate review, would apply to all cases. We do not rely on Exhibit 1047–1049, 1051, 1060, 1061, 1070, or 1071 in this decision, therefore, we deny Patent Owner’s Motion to Exclude as moot. B. Petitioner’s Motion to Exclude Exhibit 2001 (Paper 52) Petitioner moves to exclude paragraphs 13–25, 29–40, 42–43, 48–49, 56–61, and 66–75 of Exhibit 2001, which is the declaration of Dr. Brant. Paper 52. In Petitioner’s view, Dr. Brant’s “declaration is replete with inadmissible hearsay, improper legal conclusions, and testimony unsupported by reliable methods or personal knowledge.” Id. at 1. made available for cross-examination pursuant to routine discovery in our forum. Petitioner’s objections otherwise go primarily to the weight that should be accorded to Dr. Brant’s testimony, without raising any persuasive arguments for its exclusion. See generally id. (Petitioner’s arguments). Accordingly, we deny Petitioner’s Motion to Exclude Exhibit 2001. C. Petitioner’s Motion to Exclude Exhibit 2003 (Paper 53) Petitioner moves to exclude certain paragraphs of Exhibit 2003, which is the declaration of Dr. Schleicher, a named co-inventor of the ’882 patent. Paper 53. We do not rely on Dr. Schleicher’s declaration in this decision. Accordingly, we deny Petitioner’s Motion to Exclude Exhibit 2003 as moot. D. Petitioner’s Motion to Exclude Exhibit 2004 (Paper 54) Petitioner moves to exclude paragraphs 6–59 of Exhibit 2004, which is the declaration of Dr. Boutrid, another named co-inventor of the ’882 patent. Paper 54. In Petitioner’s view, Dr. Boutrid’s declaration “is riddled with inadmissible evidence, including hearsay, double hearsay, and testimony lacking personal knowledge. Much of the declaration relies on out-of-court statements from unidentified customers and unidentified UV-curable resin manufacturers, none of whom are identified or made available for examination.” Id. at 1. Much of the testimony about which Petitioner’s objects pertains to customer complaints about Patent Owner’s products, and whether maleic anhydride was included in the curable resin used by the customers, which form no part of this decision. See, e.g., id. at 4–7. We can take account of Petitioner’s objections, including Petitioner’s view that parts of Dr. Boutrid’s testimony are based on impermissible hearsay and unsound the record for appeal.

      “We agree with Patent Owner that Petitioner relies on a list of optional additives set forth in Hummel––a list that Hummel provides without any guidance as to why any particular additive would have been selected to serve any purpose, specifically in relation to the relevant layer (e). See Ex. 1005, 11:18–26 (relevant disclosure in Hummel). In other words, Hummel’s disclosure does not teach, with anticipatory specificity, a multilayer film in which a migrating compound is selected specifically for addition to layer (e).

Reply 3. the particular problem with which the inventor is involved.” In re Clay, 966 F.2d 656, 659 (Fed. Cir. 1992). Schuhmann’s release films are “reasonably pertinent” to a problem addressed in the ’882 patent, namely, providing a “release effect against adhesive substances such as resins.” Ex. 1001, 2:56– 57. So too is Hummel, which relates to removal of an inner tubular layer, “after the resin has cured,” without “tearing or seizing” during the process of removal. Ex. 1005, 7, 23.

      “For a functionally-defined genus, “the written description requirement [can be met] when the art has established a correlation between structure and function.” Ariad, 598 F.3d at 1350. Here, the challenge claims recite two types of functional limitations. First, independent claim 10 requires the coformer to have a second chemical functionality, which is defined as being complementary to the first chemical functionality via non-covalent hydrogen bonding. That is, the co-former’s second chemical functionality must be complementary to either a carboxamide, carbonyl, or amine functionality of an API via non-covalent hydrogen bonding. Second, the non-covalent hydrogen bonding between the first chemical functionality of the API and the second chemical functionality of the co-former must result in the formation of supramolecular synthons.” slip op. at 21

Patent Owner argues, for example, that Petitioner “fails to identify any embodiment of Garrison that discloses . . . an aspiration system including an aspiration pump in which negative pressure is generated in a first chamber and a second chamber when a valve is closed.” Id. at 45. Patent Owner cites, inter alia, Petitioner’s identification of “an aspiration pump that is positioned upstream of a receptacle such that the pump delivers fluid (e.g., blood) to the receptacle via positive pressure and thus cannot generate negative pressure in the receptacle”—the alleged “first chamber” identified by Petitioner.

We discuss in further detail below. whenever Garrison discloses a pump in the embodiments identified by Petitioner—whether a peristaltic pump as shown in Figures 32–34, a centrifugal pump, or the pump device 3250 shown in Figure 36—the pump is positioned to draw fluid through an inlet and expel the fluid out of an outlet via positive pressure to a downstream delivery location such as a receptacle or blood return line. Such a pump would not and could not generate negative pressure in the downstream delivery location (the receptacle the Petition alleges is the first chamber) for multiple reasons—and therefore would not generate negative pressure in any “first chamber” identified by Petitioner.

      “have been motivated to combine Schaffer and Hartley with a reasonable expectation of success. Pet. 35–40. For example, according to Petitioner, a POSA would have regarded a substitution of Schaffer’s U-shaped members for Hartley’s string as little more than a substitution of known hemostasis-valve features with known (and similar) functions to yield a predictable result. Pet. 35–36. Petitioner’s position is supported by Mr. Thornton’s testimony (unrebutted at present) that, in the field of fluid stasis valves, “[t]here were a finite number of ways to compress the resilient material in a stasis valve to create a seal in September 2017” and “Hartley and Schaffer disclose two such methods” that operate in similar and predictable ways to constrict the central lumen to form a seal. Ex. 1003 ¶¶ 82–83. We agree at this time that the proposed technique for coupling Hartley’s string to Schaffer’s actuator buttons would have been a “simple modification” within the ordinary capabilities of the skilled artisan. Id. ¶ 84 (noting a “simple” knotting attachment); see also Ex. 1007, 14:37–54 (suggesting skilled flexible wire to an actuator or housing of a fluid stasis valve). We also agree with Petitioner at this time that the POSA would have considered a more flexible filament (e.g., Hartley’s string or Eller’s wire) as providing expected benefits insofar as such a filament may more precisely and uniformly constrict the lumen against inserted tools of different sizes and shapes. Ex. 1006 ¶ 37 (Hartley’s string can “close over a range of diameters of devices passed through the valve or can close completely down and be self sealing”); Ex. 1003 ¶¶ 80–81.” slip op. at 36

      “Determining whether claims are anticipated involves a two-step analysis. The first step involves construction of the claims of the patent at issue. Claim construction is a question of law reviewed de novo.” In re Aoyama, 656 F.3d 1293, 1296 (Fed.Cir.2011). “The second step [of an anticipation analysis] involves comparing the claims to the prior art. Anticipation is a question of fact reviewed for substantial evidence.” In re Aoyama, 656 F.3d at 1296. “A prior art reference anticipates a patent claim under 35 U.S.C. § 102(b) if it discloses every claim limitation.” In re Montgomery, 677 F.3d 1375, 1379 (Fed.

      “validation” as used herein with respect to production lots refers to determining that a particular sample tests negative using the detection assay. Where a modular composite sample tests negative, all single-unit production lot samples comprising the composite sample are validated along with the respective single-unit production lots, which are thus cleared for release. Where a modular composite sample tests positive, individual single unit production lots may nonetheless yet be validated if particular respective single-unit production lot samples test negative. Ex.1002, 7:15–24 (emphasis added). The above text expressly equates “validation” to a determination that “a particular sample tests negative.” The initial definitional sentence makes no mention of “cleared for release” as necessary for “validation.” The subsequent sentence refers to “cleared for release” in the more limited situation where a particular composite sample “tests negative all single-unit production lot samples,” and, even then, the “cleared for release” language indicates a separate step that may happen after the samples are “validated.” slip op. at 21

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

      “On the current record, we are not persuaded that Petitioner has insufficiently articulated a motivation to combine or modify the asserted references. With respect to Ground 1, for example, Petitioner contends that one of ordinary skill in the art would have been motivated to modify ICMSF based on Gombas under the teaching-suggestion-motivation test so portions of the enriched, retained samples are further tested after a positive test of a composite sample by the same protocol, with a reasonable expectation of success for efficient validation. See § XII-A-1-h supra; Dickson ¶¶ 417-19. Pet. 53–54. Petitioner further argues that ordinarily skilled artisan would have sought to improve[] ICMSF with the similar methods of Gombas to yield efficient validation, which is a predictable result. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 417 (2007). In this combination, a POSA would have simply substituted steps of ICMSF, as described above, with those of Gombas so portions of the enrichment cultures are retained and are further tested after a positive test of a composite sample by the same protocol for predictably efficient validation. MPEP § 2143(I)(B); Dickson ¶ 420. Id. at 53. As such, the Petition provides specific reasons to combine ICMSF and Gombas that are consistent with the flexible test recited in KSR, including the benefit of efficient validation of the test and that the combination is a simple substitution of steps. As KSR notes, “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 US at 417.
