“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. Dec. 14–18; Ex. 1042, 14–24; Ex. 1048, 16–23; Ex. 1049, 14–17 (noting the parties’ agreement at oral hearing that there was no additional argument or evidence about whether a filament requires flexibility that was not already addressed in related matters). 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

“In this case, Patent Owner’s expert “Dr. Zhou signed the second declaration, stood behind its contents, and was available for cross-examination.” Paper 35, 4. Petitioner does not dispute this statement. Paper 39, 1. Petitioner does not identify any specific undue prejudice caused by Exhibit 2008. For example, Petitioner argues that “the failure to impress upon a witness that a statement is under oath goes to the heart of its reliability as evidence” and that “as the Board has recognized, hearsay is inherently unreliable” without specifying what statement in Exhibit 2008 lacks reliability. Paper 39, 4. Because Petitioner does not provide specific evidence of undue prejudice, we find Petitioner has suffered no such undue prejudice in this case. See Liquidia, 2021 WL 4860773 at *25. We therefore deny Petitioner’s Motion to Exclude on the basis of lack of authenticity. With regard to the assertion that Exhibit 2008 is hearsay, Petitioner objects to the exhibit because the testimony is based “on other informal and unpublished documents that are hearsay under FRE 802.” Paper 29, 1. Petitioner does not specify what such “informal and unpublished documents” are. See id.

“These arguments in the Sur-Reply are unpersuasive to show a lack of enablement first and foremost because the arguments do not specifically provide evidence showing that any purported experimentation is undue. See Sur-Reply 2–8 (asserting, but without providing evidence under any specific Wands factors, that the examples and guidance in the specification do not extend to the broad scope of all antibodies); see Wands, 858 F.2d at 737. We again emphasize that the analysis of undue experimentation does not necessarily require every Wands factor to be explicitly addressed but the analysis must be based on “weighing many factual considerations” depending on the nature of the invention and underlying art. Cephalon, Inc. v. Watson Pharms., Inc., 707 F.3d 1330, 1336 (Fed. Cir. 2013). The assertion that the claim scope is broad alone does not suffice to show a lack of enablement based on the record before us. Moreover, as we note supra, Petitioner’s claim scope argument is based on the false premise that the scope of claims 14–16 is as broad as the claim term “antibody” without taking into account all other claim elements. For example, Petitioner does not disagree with Patent Owner’s statement that “[t]he ’675 Patent’s specification discloses the structural modification site, the chemistry used to modify that residue, and working examples demonstrating the modification” (Reply 2), but asserts only that “[t]he disclosure of SSFI that only binds to IgG1 Fc domains (SEQ ID NO:1) is . . . . inconsistent with the expansive scope of the claims.” Sur-Reply 5. Petitioner’s argument that the claims encompass proteins that lack a lysine reside at a 248 position improperly excludes from the claim language the “lysine residue at 248 position . . . [as] determined by the EU numbering system” that claims 14–16 require. As Dr. Zhou testifies, “each proposed lysine residue at position 248 (EU numbering) is covalently modified with a specific attachment with a terminal bio-orthogonal click-chemistry functional group. The specification describes targeted transfer of a chemical functional group to lysine 248” and when claims 14–16 are considered in their entirety, which includes all claim elements, “[a] POSA would understand the claim itself to limit the modified antibodies to those with lysine at position 248.” Ex. 2004 ¶ 48; Ex. 2008 ¶ 47. We also note that Patent Owner states “a POSA would understand that the phrase ‘one or more modified heavy chain’ encompasses antibodies within typical DAR distributions (i.e., fractional numbers) rather than requiring a distinct process for producing antibodies bearing modified heavy chains in exact integers.” Reply 2–3. Moreover, Patent Owner states that PepTalk Presentation demonstrates that “a POSA would understand antibody conjugation products to exist as mixtures rather than discrete whole number species” because PepTalk Presentation “presents DAR values as non-integer measurements, i.e. DARs of 1.8 and 1.9 reflecting such distributions.” Id. at 3 (citing Ex. 1007, 28). According to Patent Owner, “preparations having an average DAR of approximately 1.8 (commonly referred to in practice as ‘DAR2’) may reflect typical reaction distributions in which some antibodies contain two modified heavy chains while others contain fewer.” Id. at 3 (citing Ex. 2008 ¶ 46). Petitioner does not rebut these statements. See Sur-Reply 2–8. Based on the foregoing, the evidence before us does not show any” slip op. at 27

“Contrary to Petitioner’s assertion, the Specification provides guidance as to what amount of deviation from a perfect cylinder is still “substantially cylindrical.” The Specification describes: Quick-connect system 600 includes a piston 602 that has a hollow-end bore 608 for receiving the shaft 621 of a massaging head 620. Located within the bore 608 of piston 602 is a cylindrical seat 604. Cylindrical seat 604 retains a magnet 606.

In view of the description of quick-connect system 600, the Specification sets forth a standard for ascertaining whether the bore and the seat located within the bore are “substantially cylindrical.” To wit, the bore and the seat within the bore are “substantially cylindrical” when the massaging head and magnet are respectively received therein so that the magnet in the seat and the magnet in the pocket of the massaging head can magnetically hold the massaging head firmly in place.

Dr. Pratt’s testimony shows that magnetic connectors are well known and that a POSITA would be able to determine whether the bore and the seat within the bore were “substantially cylindrical” for a secure connection of the massaging head. In view of the foregoing, Petitioner has not persuaded us that the claim term “substantially cylindrical” recited in claims 13–16 fails to inform, with reasonable certainty, the shapes of the bore and the structure within the bore.

“The invention, a reciprocating massage device, is in a predictable field, namely the electro-mechanical arts. Also, there is no evidence that the recited quick release connector is complex, even considering Patent Owner’s alleged understanding of it. Rather, Dr. Pratt testifies that a POSITA would be able to recognize a quick release connector for a particular application. According to Dr. Pratt, A person of ordinary skill in the art would consider a number of factors, depending on the context and specific application of the connector, to determine whether a connector provides a “quick release.” Such factors could include whether the connector is designed to manually and easily connect and disconnect two objects, and whether tools are necessary to do so. Other factors to be considered may be based on the specific application or operating environment. Ex. 1002 ¶ 58. Given the predictability of the electro-mechanical arts and lack of complexity of the recited quick release connector, a low level of detail is required to satisfy the written description requirement. See RAI Strategic Holdings, Inc. v. Philip Morris Prods. S.A., 92 F.4th 1085, 1090 (Fed. Cir. 2024) (“Given the predictability of electro-mechanical inventions such as the one at issue here, and the lack of complexity of the particular claim limitation at issue—i.e., reciting the length of a heating member—‘a lower level of detail is required to satisfy the written description requirement than for unpredictable arts.’” (quoting Hologic, Inc. v. Smith & Nephew, Inc., 884 F.3d 1357, 1361 (Fed. Cir. 2018)). In view of the low level of detail required to satisfy the written description requirement, Petitioner has not persuaded us that the Specification’s example of a quick release connector configured to secure the massaging head as the piston reciprocates fails to provide sufficient written description support for the “quick release connector . . . configured to secure a first massaging head while the piston reciprocates a predetermined stroke length at the first speed” recited in claim element 34[e]. 4.

“Contrary to Petitioner’s assertion, the Specification provides guidance as to what amount of deviation from a perfect cylinder is still “substantially cylindrical.” The Specification describes that quick-connect system 600 includes two magnets with opposite poles facing each other: magnet 606 in the distal end of piston 602 and magnet 624 located in cylindrical pocket 622 of massaging head 620. Ex. 1001, 6:57–67, Figs. 6, 6A. The Specification further describes that “when the shaft 621 of massaging head 620 is slid into opening in bore 608, the magnets 606 and 624 are attracted to one another and magnetically hold massaging head 620 firmly in place.” Id. at 6:67–7:3. In view of the description of quick-connect system 600, the Specification sets forth a standard for ascertaining whether the pocket is “substantially cylindrical.” To wit, the pocket is “substantially cylindrical” when the pocket receives a magnet therein so that the magnets can magnetically hold the massaging head firmly in place. Furthermore, Dr. Pratt testifies that “[m]agnetic connectors comprise a magnet on at least one of the two objects to be joined. These types of connectors are ubiquitous even today for driving threaded fasteners.” Ex. 1002 ¶ 55.

“The parties propose essentially the same formal educational background for the POSA, but we agree with Patent Owner that Petitioner’s proposed POSA definition lacks some specificity concerning the POSA’s work experience.

“That does not, however, resolve the dispute about “flexibility.” On that issue, after considering the full record developed through trial, we agree with Patent Owner that a “filament” as claimed is flexible. The claims support Patent Owner’s interpretation. Patent Owner cites the claim language, including the recitation that “the first filament [is] formed into a loop around the collapsible tubular sidewall defining a valve lumen” and that “a diameter of the valve lumen decreases in response to reducing a diameter of the loop.” As Patent Owner argues, and as we recognized at the institution stage, the claimed filament “must be flexible to constrict the valve lumen.” PO Resp. 23; Inst. Dec. 15–16; Ex. 2008 ¶ 68 (testifying that a POSA would understand this property of flexibility is essential to achieving the claimed loop formation and function). The Specification supports this understanding. Consider the “loop” embodiments as illustrated in Figures 6 or 7. Ex. 1001, Figs. 6–7. If the filament forming each depicted loop was somehow rigid, applying a force that seeks to pull the respective ends of the filament in opposing directions would not decrease the size of the loop—the loop would stay the same size and the filament would not circumferentially constrict and seal the elongate member’s lumen as described in the patent.

“Petitioner’s argument is unavailing. A steel beam or a plastic broom handle are longer than they are wide and yet conventionally rigid. And, specific to the subject matter here, as Mr. Thornton admits, machining the valve’s actuating members from plastic or metal, which Schaffer actually describes, would produce rigid members. Ex. 2005, 168:2–6; see also Ex. 2006, 152:8–10 (testifying a flexible aluminum wire would not be made from machining aluminum). Moreover, considering Schaffer’s cited drawings— Figure 32, in particular—does not show the actuating members changing shape or dynamically conforming to the outer surface of the seal module that those members are compressing, which, had that been shown, might indicate flexibility. Maybe the absence of any dynamic conformance of the surface of the actuating members is an unintended limitation or artifact of the drawing. Or maybe not, and what is shown is a rigid structure consistent with Schaffer’s other disclosures as already explained. We decline to find anticipation where Schaffer does not, with sufficient clarity and detail, describe a valve with a “filament” as claimed.21 Ultimately, on whether Schaffer describes rigid or flexible U-shaped actuating members, Dr. Zalesky’s interpretation of the reference is more plausible and we find greater evidentiary support for Patent Owner’s position on this issue. Notwithstanding Mr. Thornton’s testimony in his rebuttal declaration that a POSA reading Schaffer would have understood 21 Wasica Fin. GmbH v. Cont’l Auto. Sys., Inc., 853 F.3d 1272, 1284 (Fed. Cir. 2017) (“Anticipation requires that a single reference describe the claimed invention with sufficient precision and detail to establish that the subject matter existed in the prior art.”) (emphasis added and internal quotation marks omitted). testimony on cross-examination was equivocal—he admitted “[i]t’s not clear” whether Schaffer’s U-shaped actuating members are flexible or rigid. Ex. 2006, 115:16–23 (testifying “[t]he material properties of the U-shaped actuating members are not clearly defined in the Shafer [sic] application”). Dr. Zalesky, in contrast, has consistently testified that a POSA would have understood that Schaffer describes rigid actuating members. See, e.g., Ex. 2008 ¶¶ 66–74 (citing, inter alia, Schaffer’s illustrations of the valve in operation, and the disclosed manufacturing and assembly methods as indicating that “the actuating members 55 are rigid rather than flexible”).” slip op. at 40

“Schaffer’s valve to include a single flexible string or wire that replaces the two U-shaped actuating members would have been seen by the POSA as potentially advantageous—giving further reason for the POSA to have made that change.

On the other hand, a POSA would have recognized that a single flexible string or wire that is looped completely around the exterior of the seal module/lumen would provide more uniform constriction and compression around the outer diameter of some commonlyused tools and including tools with diverse shapes and sizes.

Patent Owner’s expert, Dr. Zalesky, does not disagree that a flexible string or wire would have carried this advantage.
