RulingsFinal written decision- Skill levelSkill level petitioner adoptedDecided for petitioner
“ways: the first is the inclusion of “or a similar field” when describing the education level of a POSITA, and second is the inclusion of “with diffusive light” when describing the experience level of a POSITA. We decline to include either of these additional requirements in the definition of the level of ordinary skill. As to the first difference, Patent Owner does not explain what aspects of computer science would make it a field similar to the others listed, nor what additional engineering coursework would suffice. See Ex. 2004 ¶ 25. Nor does Patent Owner explain, generally, what makes a field “similar” to the ones listed or how to make that determination. We determine that Patent uncertainty into the definition and, therefore, do not adopt it. As to the second difference, Patent Owner proposes that the level of skill include two years’ experience with “diffusive light micro-optic security features.” The ʼ294 patent, however, does not mention “diffusive light.” Instead, the challenge claims and the written description of the ʼ294 patent use the term “ambient light.” See, e.g., Ex. 1001, Abstract, 20:50, 59. Ambient light, such as sunlight, includes both parallel and diffuse light. See Ex. 1055, 97:21–98:8; Ex. 1006 ¶ 54 (describing the use of sunlight or ceiling light). The ʼ294 patent mentions ambient light in an ordinary manner without discussing any distinctions between parallel light and diffuse light or giving any significance to the nature of diffuse light and its effects on the invention. We, therefore, adopt Petitioner’s definition of level of ordinary skill except that we find that the phrase “at least” in Petitioner’s proposed definition creates a vague, open-ended upper bound for the level of ordinary skill, and we therefore do not adopt that aspect of the proposal.” slip op. at 11

“references expressly teach but what they would have suggested to one of ordinary skill in the art at the time the invention was made”) (quoting In re Lamberti, 545 F.2d 747, 750 (CCPA 1976)) (emphasis added); Syntex (U.S.A.) LLC v. Apotex, Inc., 407 F.3d 1371, 1380 (Fed. Cir. 2005) (“What a reference teaches a person of ordinary skill is not . . . limited to what a reference specifically ‘talks about’ or what is specifically ‘mentioned’ or ‘written’ in the reference.”). Here, Petitioner has established that Fuhse262 discloses mirrors that reflect light rays converging at a light spot. Ex. 1006 ¶¶ 95–96, Fig. 10. Dr. Hesselink credibly testifies that while Fuhse262 depicts rays that form a light spot, the rays depicted are “chief rays” that depict only the center rays of light for each optical element. Ex. 1003 ¶¶ 169–170. Ambient light, however, reflects from the entire surface of the mirrors and forms reflected beams of light, not just the center rays aimed at the center point. Id. ¶ 170. According to Dr. Hesselink, the “chief ray” is representative of the larger bundle of rays that form the beams of light reflected off of the mirrors. See Id. ¶ 44. The volume of the voxel is set by the intersection of these beams and the center of the voxel is the point at which the center rays of each beam intersect. Id. ¶ 171. Although Dr. Lindstrand testifies a POSITA would not have understood Fuhse262 to disclose creating a voxel (Ex. 2004 ¶ 43), Dr. Lindstrand does not dispute Dr. Hesselink’s testimony that light would reflect off of the entire surface of Fuhse262’s mirrors and form reflected beams of light. See Ex. 2004 ¶¶ 42– 58; Ex. 1055, 112:15–21 (“You also agree the ambient light would not just strike the center of the surface, it would strike the entire surface, correct? . . . THE WITNESS: I would say that that is a fair and accurate description.”) would reflect off the entire surface of Fuhse262’s micromirrors and would create a voxel when they intersect with each other, provides sufficient support demonstrating how a person of ordinary skill in the art would have understood Fuhse262’s disclosure of light rays being reflected off of mirrors and converging at a light spot shown in Figure 10. See Unification Techs. LLC v. Micron Tech. Inc., 2024 WL 3738401 at *7 (Fed. Cir.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“As to Petitioner’s more general allegations regarding motivation to combine the embodiments of Fuhse262 and reasonable expectation of success, we agree with Petitioner for the reasons provided in the Petition and summarized above. Specifically, we agree with Petitioner that Fuhse262 concave mirrors and lenses with embodiments that use micromirrors. See Ex. 1006 ¶ 83 (“In order to still obtain a higher resolution in the produced light-spot image with an unchanged high floating height, the large mirrors or lenses used in the previous exemplary embodiments are each replaced by a plurality of smaller micromirrors or microprisms, which together have essentially the same optical effect as the original optical element.”). We also agree that the embodiments of Fuhse262 build on each other and often refer back to each other. For example, Fuhse262 expressly refers back to “previous exemplary embodiments” when explaining that micromirrors may replace other optical elements in the various embodiments. Ex. 1006 ¶ 83. Fuhse262’s Figures 8(a) through 8(d) build on each successive example, adding and modifying the configuration of mirrors disclosed in the previous figure. See Id. ¶¶ 88, 94 (explaining that Figure 8(b) is based on Figure 8(a) but shows mirrors arranged in checkerboard-like manner and Figures 8(c) and 8(d) further modify the configuration with every “fourth field” and “ninth field” respectively being assigned to specific light spots.) Fuhse262 also explains that Figure 9 is a sectional view of Figure 8 and that Figure 10 illustrates the “calculation of the flat mirror surfaces of the micromirrors” of Figures 8 and 9. Id. ¶¶ 91, 95. For the aforementioned reasons, we determine that Petitioner has demonstrated, by a preponderance of the evidence, that a person of ordinary skill would have been motivated to combine the teachings of the relied upon embodiments of Fuhse262.” slip op. at 18

“For purposes of this Decision, we adopt the definition of the level of ordinary skill in the art proposed by Petitioner. As to the inclusion of physics in Petitioner’s definition, Dr. Singhose (a professor of mechanical engineering) testifies as to why undergraduate mechanical engineering degree holders would have the requisite knowledge here, but does not testify that undergraduate physics degree holders would not. See Singhose Decl. ¶¶ 2, 27, 28. In addition, Patent Owner and Dr. Singhose require “a four-year degree in mechanical engineering or a closely related field,” but fail to identify what fields are “closely related.” See Prelim. Resp. 11; Singhose Decl. ¶ 27. Based on the Morse Declaration, we are persuaded at this stage that a hypothetical undergraduate physics degree holder would have adequate knowledge for one of ordinary skill in the art of the invention here. See Morse Decl. ¶ 31. As to the requisite years of experience proposed in the definitions— three for Petitioner versus “at least one” for Patent Owner—we note that Patent Owner’s definition is broader than, but includes, Petitioner’s definition. Moreover, for both the inclusion of physics and the years of experience issues, Patent Owner acknowledges that the arguments in the Preliminary Response “are not impacted based on which definition is applied.” Prelim. Resp. 12 (citing Singhose Decl. ¶¶ 30–34).

“B. Claim Construction In inter partes reviews, the Board interprets claim language using the same claim construction standard that would be used in a civil action under 35 U.S.C. § 282(b), as described in Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc). See 37 C.F.R. § 42.100(b). Under that standard, we generally give claim terms their ordinary and customary meaning, as would be understood by a person of ordinary skill in the art at the time of the invention, in light of the language of the claims, the specification, and the prosecution history. See Phillips, 415 F.3d at 1313–14. Although extrinsic evidence, when available, may also be useful when construing claim terms under this standard, extrinsic evidence should be considered in the context of the intrinsic evidence. See id. at 1317–19. Petitioner does not propose express constructions for any claim terms. Pet. 12. Patent Owner also does not propose any express constructions. See Prelim. Resp. 12. On the current record, we need not construe explicitly any claim terms. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

“We agree with Patent Owner that 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 or engineering 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 ¶ 36; Ex. 2001 ¶ 73. 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.

“As noted above, the challenged claims require a “filament formed in a loop around the tubular sidewall” where, when a portion of the filament is pulled away from the loop, the loop’s diameter reduces, thereby reducing the diameter of the lumen formed by the tubular sidewall to seal the valve. See supra Section II.D. Every embodiment in the ’291 patent where the filament is described as forming a “loop” in the manner claimed involves a filament that is necessarily flexible. See, e.g., Ex. 1001, 13:17–29, Figs. 6–7. The valve would not work if the looped filament were somehow inflexible— pulling an end of the filament would not change the diameter of the loop, and the valve would not seal.

“We are unpersuaded that Schaffer describes a valve with a filament as claimed. If, as construed above (supra Section III.C), the filament requires flexibility, Petitioner has not demonstrated that Schaffer describes such a feature in its valves. Instead, we agree with Patent Owner that a POSA would more likely understand Schaffer’s two U-shaped actuating members as being rigid features. Prelim. Resp. 33–36. We agree with Patent Owner that Petitioner implicitly admits that Schaffer’s actuating members are rigid leakage around tools inserted through the central lumen when in use and compared to the use of a flexible string or wire (of Hartley or Eller). Prelim. Resp. 34 (citing Pet. 51). We also find Dr. Zalesky’s interpretation of Schaffer more plausible than Mr. Thornton’s on the question of whether a POSA would have regarded Schaffer’s actuating members as being rigid structures. Ex. 2001 ¶¶ 78–85 (testifying, inter alia, that a POSA would have understood from Schaffer’s disclosure about making the actuator and actuating members from machining pre-existing amounts of metals and/or plastics, and further explaining that flexible parts would deform and be difficult to machine through conventional techniques); Ex. 1005 ¶¶ 81–82. Mr. Thornton opines that Schaffer’s disclosed manufacturing techniques for the actuator/actuating members are only examples and “a person of ordinary skill in the art could have simply purchased pre-made [flexible] flat wire or plastic tapes or ribbons.” Ex. 1003 ¶ 96. Such opinion invokes, at best, obviousness-based reasoning. This does not establish that Schaffer alone describes a filament sufficient to anticipate the claims. Furthermore, Mr. Thornton’s opinion that a POSA “would have understood that Schaffer’s U-shaped actuating members would have preferably been formed from a thin, flexible material” finds no support in Schaffer itself. Ex. 1003 ¶ 95. This opinion is also at odds with his testimony in related cases about an alleged formation of gaps with Schaffer’s actuating members, which suggested those members had a set “size” and lacked flexibility. See IPR2025-01157 (Ex. 1003 ¶ 81 (testifying a POSA “would have recognized that Hartley’s flexible string may better seal the valve than Schaffer’s metallic/plastic actuating members” because, “if a tool did not fit the size of” slip op. at 31

“Mr. Bauer further testifies: For electric-powered breast pumps, the only two options for providing electricity to the pump was either via a wire plugged into an outlet or via a battery, as would have been well-known to a POSITA. It would have been obvious for a POSITA to utilize a battery as the power source for Furrer’s pump as it was one of the two available options and would have provided known benefits. Ex. 1003 ¶ 93. As to why this a person of ordinary skill would have chosen the option of a battery powered breast pump, Mr. Bauer testifies that: Selection of battery power for Furrer’s pump would have beneficially provided a portable system that was usable during travel. Additionally, such a configuration would have allowed the user to move freely about a room, or be positioned in a location within a room without being tethered to a wall plug, allowing the user to, for example, sit or lay in the most convenient location while using the system without having to worry about being close to an outlet. Such mobility provided by selecting battery power for Furrer’s pump would have particularly aligned with Furrer’s suggestion for a ‘hands-free’ and discrete solution. Id.

“We agree with Patent Owner that 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 or engineering 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. 2024 ¶ 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, such devices. Ex. 1001, 1:16–54 (background of the invention). Such devices include, but are not necessarily limited to, hemostasis valves and catheters for minimally-invasive vascular surgeries. Id. And, consistent with the testimony of the parties’ experts, the POSA need not have had firsthand 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); Ex. 2030 (Thornton Tr.), 180:13–19. 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.” Ex. 1037, 74:5–75:1. Lastly, a POSA would have had an understanding of such devices’ design requirements as determined by the needs of the physician, patient, and procedure, which understanding may be informed by work experience and/or study.

“That does not, however, address the dispute about “flexibility.” On that issue, the argument and evidence at this stage tends to favor Patent Owner’s position that a “filament” as claimed is flexible. 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.” Prelim. Resp. 14–16 (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 appear at this stage more consistent with the view that the filament is characteristically flexible, not rigid. So too, as we explained in related matters, the ’921 patent’s loop 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 not manifestly 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 (similar to the loop embodiments, depicting structures 150-A and 150-B forming sub-filaments of the bight(s)). 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” slip op. at 14

“Based on the current record, we are unpersuaded that Schaffer describes a valve with a filament as claimed. If, as construed above (supra Section III.C), a filament requires flexibility, Petitioner has not demonstrated that Schaffer describes such a feature in its valves. Instead we agree with Patent Owner that Petitioner “implicitly admits” that Schaffer’s actuating members are rigid insofar as Petitioner argues those members would form gaps for fluid leakage around tools inserted through the central lumen when in use and compared to the use of a flexible string or wire (of Hartley or Eller). Prelim. Resp. 29 (citing Pet. 36). Moreover, we find Dr. Zalesky’s interpretation of Schaffer more plausible than Mr. Thornton’s on the question of whether a POSA would have regarded Schaffer’s actuating members as being substantially rigid structures. Ex. 2024 ¶¶ 92–100 (testifying, inter alia, that a POSA would have understood from Schaffer’s disclosure about making the actuator and actuating members from machining pre-existing amounts of metals and/or plastics, and further explaining that flexible parts would deform and be difficult to machine through conventional techniques); Ex. 1005 ¶¶ 81–82. Mr. Thornton testifies that Schaffer’s disclosed manufacturing techniques for the actuator/actuating members are only examples and “a [and flexible] flat wire or plastic tapes or ribbons.” Ex. 1003 ¶ 79. Such testimony invokes, at best, obviousness-based reasoning. This does not establish that Schaffer alone describes a filament sufficient to anticipate the claims. Trintec Indus., Inc. v. Top-U.S.A. Corp., 295 F.3d 1292, 1296 (Fed. Cir. 2002) (explaining that the “test for novelty” requires “strict identity”); Jamesbury Corp. v. Litton Indus. Prods., Inc., 756 F.2d 1556, 1560 (Fed. Cir. 1985) (holding “anticipation is not shown by a prior art disclosure which is only ‘substantially the same’ as the claimed invention”), overruled on other grounds, A.C. Aukerman Co. v. R.L. Chaides Constr. Co., 960 F.2d 1020 (Fed. Cir. 1992) (en banc).
