      “appears to be generally consistent with the level of skill presented in the cited prior art. See generally, e.g., Exs. 1005–1008; see also Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art itself may reflect an appropriate level of skill in the art). However, as at institution, we reject the portion of Petitioner’s proposed definition that includes having “access to other individuals with that knowledge and experience,” as not reflecting the individual level of skill of a given skilled artisan. See, e.g., Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d 955, 962 (Fed. Cir. 1986) (holding that “[t]he person of ordinary skill is a hypothetical person who is presumed to be aware of all the pertinent prior art.”) (emphasis added, footnotes omitted); but see Indivior Inc. v. Dr. Reddy’s Labys., S.A., 930 F.3d 1325, 1343 (Fed. Cir. 2019) (no clear error in determination that “a person of ordinary skill . . . ‘would be on a team with an engineer or scientist . . . .’”). Consequently, we find the person of ordinary skill in the art was a person who had a Ph.D. in immunology, molecular biology, cellular biology, or a similar field, or an M.D. with similar experience, and had at least five years of experience with antibodies and antibody engineering.” slip op. at 11

      “We find that combining Liu’s BA03 antibody with Wei’s ADC platform would have been desirable, predictable, and routine for the ordinarily skilled artisan based on the facts that: (1) cetuximab was a wellknown and well-studied, U.S. regulatory approved, anti-EGFR antibody that would have served as a starting point for new cancer therapies; (2) humanization of therapeutic antibodies is generally desired (and “[e]very antibody can be humanized” and it is advantageous according to Patent Owner’s counsel); (3) BA03 was a well-known humanized version of cetuximab that had several known advantages over cetuximab in addition to lower immunogenicity from humanization; and (4) Wei taught a similar cetuximab-derived antibody, and a humanized cetuximab-derived antibody, each provided in an ADC with a well-known and validated off-the-shelf linker-drug platform, i.e., vc-MMAE, that exhibited a strong anti-tumor response. See, e.g., Ex. 1001, 1:57–2:32, 2:50–3:1, 5:6–53, 18:3–33, 19:26– 29; Ex. 1002 ¶¶ 14, 38, 42–43, 45–53, 56–73, 84–92, 109–117, 178–189, 202–271; Ex. 1005 ¶¶ 9–10, 229–232, 434, 437, 476, 491–506, 664–675, 685, 688, 715, 732, 1103, 1092–1141; Ex. 1008 ¶¶ 3–6, 60, 74, 141–160; Ex. 2027 ¶¶ 7–8, 38, 50, 57 (confirming our understandings regarding the claimed antibody and linker-drug payload); Ex. 2023, 173, 300; see also Resp. 1, 5–6, 23 (Patent Owner made the “choice” to use the prior-art-known BA03 antibody, and known-candidate cytotoxic payload MMAE); Hr’g Tr. 34:20–23, 36:6–38:20, 47:16–50:16 (Patent Owner’s counsel’s argument).

      “A. Level of Ordinary Skill in the Art Baby Jogger does not dispute Evenflo’s definition of the level of ordinary skill in the art, which is that a person of ordinary skill in the art (hereinafter, “one skilled in the art”) would have had “a bachelor’s degree in a relevant field (e.g., mechanical engineering or industrial design) and at least two years of product design experience and/or industry experience with juvenile products” and that “[m]ore education can replace product design experience, and vice versa.” Pet 8 (citing Ex. 1001 ¶¶ 31–33); PO Resp. generally.

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

      “At the outset, we note that the claim language requires only that “the first seat and the second seat” be arranged in an inline descending configuration, not that the seat’s mounting points or other physical connections be so arranged. Ex. 1010, 17:31–33. Baby Jogger improperly reads “seats” out of the claim and substitutes the seat’s “mounting points” on the frame. A proper reading of the claim language focuses on what happens when both seats are connected to the frame, not where they are so connected. In other words, “when connected to the frame” simply emphasizes that both seats must be connected to the frame to form the inline descending configuration, as opposed to the single stroller embodiment of Figure 1, where there cannot be an inline descending configuration because only one seat is connected to the frame and the other seat is removed, i.e., not connected to the frame. That reading is supported by the specification of the ’682 patent,” slip op. at 9

      “We find that testimony persuasive, for it shows what one skilled in the art would have recognized the 2008 Provisional as necessarily disclosing. The relevant inquiry is whether the disclosure of the prior application “convey[s] with reasonable clarity to those skilled in the art that, as of the filing date sought, the inventor was in possession of the invention.” PowerOasis, 522 F.3d at 1306 (emphasis in original; citation omitted). “While a prior application need not contain precisely the same words as are found in the asserted claims, . . . the prior application must indicate to a person skilled in the art that the inventor was ‘in possession’ of the invention as later claimed.” Id.

      “Instead, Evenflo’s argument rests on isolating the statement—“A similar sub-frame arrangement is disclosed in [Offord ’797]”—from the remainder of the passage in which that statement appears in order to arrive at a reason to incorporate the reversibility teaching of Offord ’797. However, when that statement is read in the context of the full passage in which it appears, nowhere does that passage suggest reversibility as the reason for referencing Offord ’797. More accurately, it suggests a different reason that relates to a curved lug 108 by which sub-frame 100 rests on the stroller’s main frame 4 to carry the weight of the stroller’s two occupants— When the interface components 100 are attached to the frame assembly 4 they form a sub-frame of the frame assembly 4, and when the child-carrying units are mounted thereon, one behind the other, they are in a compact echelon formation, one of the connector sockets 106 of each component 100 being at a higher level in relation to the ground than the other connector sockets 106. The higher connector socket 106 and further connecting leg 102 are both connected to the respective opposite ends of an upper mounting piece 107. In addition, on the inner side of the lower connector sockets 106 there is a downwardly curved lug 108 which serves to rest upon a part of the basket frame 44, such that the weight of two infants is fully supported by the frame assembly 4. A similar sub-frame arrangement is disclosed in [Offord ’797]. Ex. 1051, 9:23–36 (emphasis added). That passage shows that, rather than reversibility of the sub-frame, the reference to Offord ’797 is more aptly directing the reader to the arrangement and details of a similarly curved lug structure in the stroller sub-frame of Offord ’797. Indeed, Figures 5 and 6 of Offord ’797, reproduced below, disclose just such a curved lug in the context of “corner pieces 20” having “channel 21.” Ex. 1054, 4:10–23.” slip op. at 53

Pet. 66 (citing Ex. 1003 ¶¶ 189, 236). Patent Owner does not dispute this rationale.

      “We begin our analysis with the language of the claims. Phillips, 415 F.3d at 1312; see also SuperGuide Corp. v. DirecTV Enterprises, Inc., 358 F.3d 870, 874–875 (Fed. Cir. 2004) (“There is a ‘heavy presumption’ that the terms used in the claims ‘mean what they say and have the ordinary meaning that would be attributed to those words by persons skilled in the relevant art.’”). Claim 1 recites, in relevant part, “said fluid flow control structure being a layered structure comprising a non-perforated fibrous polymeric layer and a first perforated polymeric layer.” Ex. 1001, 13:62–64 (limitation [1h]). The plain language of claim 1 does not address additional properties of the perforated polymeric layer; the language of the dependent claims, however, imposes additional limitations on the properties of the perforated polymeric layer such as a particular basis weight (claim 2), a particular makeup (claim 3), a particular aperture size (claim 7), a particular open area (claim 8), and that it “is a three-dimensionally formed layer having penetrating apertures extending from a first surface of the first perforated polymeric layer towards a second surface of the first perforated polymeric layer and forming protrusions on said second surface” (claim 4). The dependent claims’ additional language indicates that the term “perforated” within the term “perforated polymeric layer” in claim 1 is not limited in the manner asserted by Patent Owner’s proposed construction.” slip op. at 12

      “layer pierced through with holes or apertures,” we are persuaded that Petitioner meets its burden as to this limitation. Petitioner argues that under our construction, Bergstrom’s express disclosure of forming element 60, and Bergstrom’s explanation of the properties of forming element 60, meets the claimed “perforated polymeric layer” limitation. Pet. 38–41 (citing Ex. 1002 ¶¶ 114–117). Even under Patent Owner’s proposed construction, Petitioner argues, forming element 60 would also allow free flow of liquid bodily waste. Pet. Reply 3– 4 (citing Ex. 1021 ¶¶ 20–23). Importantly, Bergstrom expressly discloses: “suitable materials for the forming element 60 are plastic films, perforated plastic films and reinforced tissue or reinforced nonwoven materials.” Ex. 1004, 10:1–4. This express disclosure is clear. Even though the forming element 60 in Bergstrom might be “typically” liquid-impermeable (Ex. 1004, 9:24–30), that does not preclude a layer that is perforated, particularly where Bergstrom expressly discloses a perforated plastic film as one of the possibilities for forming element 60. Ex. 1004, 10:1–4. Additionally, although Patent Owner focuses on Bergstrom’s disclosure that forming element 60 is “typically liquid-impermeable” (PO Resp. 58–60; Ex. 1004, 9:24–30), we do not view Bergstrom’s use of the word “typically” as mandating that the forming element always be liquid impermeable. We agree that the word “typically” does not mean “always” and that such a reading would render “typically” superfluous. Pet. Reply. 5. We do not find any ambiguity in Bergstrom’s disclosure regarding possible use of perforated plastic films for its forming element 60; whether or not the forming element 60 provides other functions (like stiffness) does not dictate whether it may also be perforated, or be part of a fluid flow control structure. On this point, we credit Petitioner’s arguments and explanation, as supported by Dr. Pourdeyhimi’s testimony. Pet.

      “from the start” (PO Resp. 29), and that “using all or part of [Glaug’s] fluid-acquisition system in place of [Nakazawa’s] diffusion sheet would be antithetical to the teachings of both references” (id. at 35), we agree that the proposed combination of Nakazawa’s structure with the layers of Glaug is sufficiently motivated and reasonably expected to result in a successful article, for the reasons articulated by Petitioner. See, e.g., Pet. 59–65; Ex. 1002 ¶¶ 176–192. Namely, although fluid may flow in both Z directions in Nakazawa (PO Resp. 30), that does not foreclose the combination with Glaug in the manner proposed by Petitioner. See generally Ex. 1002 ¶¶ 176–192; see id. ¶ 184 (detailing the mechanics of the proposed combinations), ¶¶ 188–191 (discussing motivation to combine), ¶ 192 (discussing reasonable expectation of success). The combination can be achieved “either by adding the lower acquisition layer 64 [of Glaug] to diffusion sheet 63 [of Nakazawa], or by replacing diffusion sheet 63 [of Nakazawa] with the two-layer fluid acquisition system 34 [of Glaug],” and as persuasively explained by Dr. Pourdeyhimi, the arrangement constitutes a “fluid flow control structure.” See Ex. 1021 ¶¶ 45–47. Additionally, the diffusion sheet in Nakazawa can be made from the same material as used in Glaug, namely, AquiDry™. Id. ¶¶ 53–55; see also Tr. 17:25–18:3 (“although Glaug does not specify the name AquiDry in its disclosure, Patent Owner’s expert testified that it’s his understanding that Glaug is discussing the AquiDry material, the same material that is in Nakazawa . . . . they disclose using the same material, and Nakazawa says this material work[s]”). When asked if Patent Owner’s expert had any concerns that AquiDry was not the same as between Nakazawa and Glaug, Patent Owner’s counsel replied “They are the same, Your Honor. And we embrace that.” Tr. 46:8–12; see also id. at 58:19 (Petitioner’s counsel commenting about Patent Owner’s counsel: “they agree, AquiDry is used in both Nakazawa and Glaug”). Thus, Patent Owner’s argument that Nakazawa’s diffusion sheet and Glaug’s fluid acquisition layer have different purposes because Nakazawa’s diffusion sheet allegedly must promote fluid flow in the Z-directions, both toward and away from the body (PO Resp. 29–37; Ex. 2004 ¶¶ 26–28, 30– 35)) is not clearly supported by Nakazawa, and is also contravened by the shared disclosure of Nakazawa and Glaug as to the composition of the disputed layer. We have reviewed the complete record, including Patent Owner’s and Mr. Sheldon’s assertions that Nakazawa requires promoting fluid flow in both Z-directions (see id.), but find that Petitioner carries its burden to demonstrate that one of ordinary skill in the art would have been motivated to combine Nakazawa and Glaug with a reasonable expectation of success. On this complete record, Petitioner explains sufficiently why and how a person of ordinary skill would modify Nakazawa’s diffusion sheet, i.e., to use Glaug’s fluid acquisition system, or the lower non-perforated layer of its fluid acquisition system, in Nakazawa, and Petitioner provides well-supported reasons for doing so.” slip op. at 36

Facts to be considered in analyzing the issue, other than testimonial evidence, include, for example, whether there is an established publisher, a copyright date/notice, other publication-related dates (impression, printing, etc.), an ISBN number, citations to the reference before (and to a lesser degree, after) the priority date at issue corroborating its availability and/or that the publisher was established, and whether the reference’s “purpose of publishing . . . was ‘dialogue with an intended audience.’” Id. at *10–21 (citing Valve Corp. v.

      “Patent Owner’s proposed experience of two years in the field of wireless/inductive charging is a bit more specific than Petitioner’s proposal of three years of experience with circuits and “familiarity with power electronics and inductive power transfer circuits.” We, however, discern little material difference between the parties’ proposed definitions. Petitioner’s definition is consistent with the level of ordinary skill reflected in the prior art references of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (recognizing that the prior art itself may reflect an appropriate level of skill in the art). For purposes of this decision, we apply Petitioner’s definition of the person of ordinary skill in the art. We note, however, that were we to adopt Patent Owner’s assessment, the outcome of this Decision would be the same.” slip op. at 9

      “Even if the Specification identified “linear regulation/control as being a central aim” of the ’696 patent, Patent Owner has offered no persuasive reason why a linear-control-related limitation should be read into independent claim 1, and we decline to do so. Hill-Rom Servs., Inc. v. Stryker Corp., 755 F.3d 1367, 1371 (Fed. Cir. 2014) (“While we read claims in view of the specification, of which they are a part, we do not read limitations from the embodiments in the specification into the claims.” (citing Liebel–Flarsheim Co. v. Medrad, Inc., 358 F.3d 898, 904 (Fed. Cir. 2004))); cf. Ex. 1105, 40 (the District Court, in the parallel litigation, excluding a witness’s testimony that the “substantially different” term requires “allow[ance] for some incremental change (increase or decrease) in frequency while remaining in the near-linear/linear regions” because, inter alia, Powermat “fails to offer any particularized arguments explaining why the ‘allow[ance]’ construction is proper.” (alterations in original)). Patent Owner also relies on dependent claim 2, which depends from independent claim 1. PO Resp. 28–29. Dependent claim 2 adds to claim 1 the requirement that the driver be configured to increase and decrease the transmission frequency when a particular signal is received. See Ex. 1001, 28:47–54. Patent Owner asserts that this means that the driver is configured to increase/decrease the “substantially different” frequency, namely a frequency that lies within the near-linear region of a frequency-amplitude graph, and argues that, “[i]n reading claim 2 as a whole, a POSITA would understand that the ’696 Patent is directed to a linear control technique for predictably regulating power transfer.” PO Resp. 28–29 (citing Ex. 2006 ¶ 101). Even if dependent claim 2 called for linear control as Patent Owner appears to assert, we would not read such a limitation into the underlying independent claim. See Karlin Tech., Inc. v. Surgical Dynamics, Inc., 177 F.3d 968, 971–72 (Fed. Cir. 1999) (“The doctrine of claim differentiation . . . normally means that limitations stated in dependent claims are not to be read into the independent claim from which they depend.”); but see PO Sur-reply 4 (arguing for a narrower interpretation of independent claim 1 because it must be read in the context of the entire patent, which includes dependent claim 2).

      “Dr. Woods testifies that Onishi’s “Paragraph [0180] is unambiguous that FIG. 4 does not illustrate the frequency-response of a single coil in isolation, but instead illustrates the ‘resonance characteristics of the primary coil L1 and the secondary coil L2’ when the coils are brought in electromagnetic proximity of each other for charging—i.e., in an inductively coupled state.” Ex. 1101 ¶ 18. Dr. Woods, in support of his opinion, notes that Onishi’s legend for Figure 4 describes f0 as the “RESONANCE FREQUENCY IN LOAD-CONNECTED STATE.” Id. We find Dr. Woods’s testimony more credible than Dr. Mercier’s. We disagree with Patent Owner’s argument (PO Resp. 35) that Petitioner’s reliance on Onishi’s Figure 4 is misplaced, and we find that Figure 4 discloses a resonant frequency of the inductive couple between the primary and secondary coils, as recited in limitations 1.4 and 1.7.” slip op. at 32

      “We do not find Patent Owner’s arguments persuasive. We agree with Petitioner that Patent Owner’s arguments are incorrectly premised on a hypothetical combination involving the bodily incorporation of the two references’ specific structures. See Pet. Reply 17. “The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . . Rather, the test is what the combined teachings of the references would have suggested to those of ordinary skill in the art.” In re Keller, 642 F.2d 413, 425 (CCPA 1981); see also In re Sneed, 710 F.2d 1544, 1550 (Fed. Cir. 1983) (“[I]t is not necessary that the inventions of the references be physically combinable to render obvious the invention under review.”); In re Nievelt, 482 F.2d 965, 968 (CCPA 1973) (“Combining the teachings of references does not involve an ability to combine their specific structures.”). Rather, “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 Int’l Co., 550 U.S. at 417. Petitioner’s proposed combination is the application, to Onishi’s charging system, of Flowerdew’s general teaching of the technique of using an alignment mechanism in order to optimize the alignment of the inductive coils and to maximize the inductive coupling. See, e.g., Pet. 15 (“[A] POSITA would have been motivated to implement Onishi in a manner that includes an alignment mechanism as suggested by Flowerdew (e.g., a dished recess or other shaped surface feature, a directional logo/marker, or both) so that the primary and secondary coils would be more readily ‘optimized’ for alignment and the inductive ‘coupling is maximized.’”). Flowerdew teaches, for example, that, with the use of a dished charging surface, the secondary unit “tends to align in one axis” and “[t]his alignment is such that the coupling between a solenoid receive coil in secondary unit 304 and the charging coils of charger 302 is maximized.” Ex. 1005, 11:25–52. Petitioner, with the supporting testimony of Dr. Woods, contends, and we agree, that a person of ordinary skill in the art “would have been sufficiently skilled to implement [the proposed] combination given the predictable techniques disclosed in each reference and the relatively advanced state of the art at the time.” Id. at 17 (citing Ex. 1003 ¶ 55). We determine that Petitioner has shown that the proposed combination teaches or suggests the subject matter of limitation 1.3 and that Petitioner has set forth adequate and persuasive reasons with rational underpinning as to why a person of ordinary skill in the art would have modified Onishi’s system to utilize an alignment mechanism. We also determine, for the reasons stated by Petitioner, that a person of ordinary skill in the art would have had a reasonable expectation of success in making the proposed combination.

      “2. Patent Owner’s Arguments Concerning Claim 1 and Our Analysis a. Reasonable Expectation of Success in modifying catheters to less than 6 Fr Patent Owner asserts “Petitioner has failed to perform a proper obviousness analysis by not adequately demonstrating a reasonable expectation of success in modifying Fogarty.” PO Resp. 35. Patent Owner asserts “the category of ‘Fogarty catheters’ is broad and diverse” and “Dr. Resnick admits he has no idea whether Chengod’s or Deaton’s catheters have interior constructions similar to that of the cited Fogarty reference.” Id. at 35‒36 (citing Ex. 2002, 52:16‒57:1). Patent Owner asserts that Petitioner has therefore not demonstrated that a PHOSITA would have a reasonable expectation of success in modifying the particular catheter taught by the cited Fogarty patent (Ex. 1004) to the claimed size when considering the shaft has a spring coil and braid in addition to the outer tube and lumen. Id. Petitioner responds “(1) Fogarty did not indicate the catheter’s size; (2) Fogarty catheters smaller than 6 Fr were known and disclosed in Chengod (and Deaton); and (3) sizing Fogarty’s catheter less than 6 Fr would work (i.e., reasonable expectation of success) because it did work.” Pet. Reply 19. Petitioner asserts that Yassinzadeh “shows a catheter that is less than 6 Fr and that includes a similar spring coil construction as found in the Fogarty patent” where the “dilator 150 has a diameter of either 5 Fr or 6 Fr.” Id. at 19‒20 (citing Ex. 1033 ¶¶ 86‒97 (“Yassinzadeh”)). Petitioner asserts that Yassinzadeh’s “analogous construction being less than 6 Fr confirms a PHOSITA would have a reasonable expectation of success in sizing the catheter in Fogarty (Ex-1004) less than 6 Fr.” Id. at 20 (citing Ex. 1034 ¶ 97).

      “Ex. 1011 ¶ 77. In short, although paragraph 77 of Collinge is cited in the Petition and addresses both issuer processing server 308 and acquirer processing server 312, Petitioner relies on and shows that issuer processing server 308 (not acquirer processing server 312) receives “an authorization request to authorize the transaction from the POS terminal,” as required by claim 10. Pet. 58–59; Pet. Reply 16–18; DR Req. Opp. 2–4. Furthermore, there is no dispute that in Collinge the “authorization process” is performed at issuer processing server 308 in response to a request it receives. Ex. 1011 ¶ 77 (“The issuer processing server 308 may then validate the application cryptogram”). Claim 10 requires “performing an authorization process” including “receiving an authorization request to authorize the transaction from the POS terminal” at the remote computer system. We recognize that acquirer processing server 312 facilitates receiving transaction information from the POS terminal and communicating an authorization request to the issuer processing server 308. See Ex. 1011 ¶ 77. It is merchant point-of-sale terminal 120, however, that transmits “the received payment information and any additional transaction information (e.g., transaction amount, merchant identifier, etc.) to the acquirer processing server 312,” so that “acquirer processing server 312 may then generate and submit an authorization request for the financial transaction” through payment network 124 to issuer processing server 308 for validation. Id. Thus, Petitioner shows that in Collinge the request received by the issuer processing server 308 is “from” the POS terminal, as required by claim 10.

We credit Dr. Fiske in this regard, who explains that “the functionality performed” in the components in the “Blue-Box Structures,” that is Collinge’s Cloud Systema and Issuer System, “share a ‘connection 178’ therebetween,” as shown in Figure 7 of the ’095 Provisional. Ex. 1050 ¶ 43. We also considered Dr. Easttom’s opinion that Collinge’s Cloud System 110 and Issuer System 108 (see Ex. 1011, Fig. 7) are not one computer system because, in his view, each item “is (one or more) separate systems that operated independently from the others.” Ex. 2009 ¶ 150; see also PO Resp. 36–37 (arguing that Petitioner presents “no evidence” to show that allegedly “distinct” components are part of one remote computer system). We find Dr. Easttom’s opinion untenable because it is contrary to the express disclosure of Collinge, which demonstrates that, rather than operating “independently,” Cloud System 110 and Issuer System 108, and specifically remote-SE system 110 and issuer processing server 308, are connected and operate together through that connection, remotely from the mobile device. The Final Written Decision expressly agrees with and adopts Petitioner’s contentions with regard to claim 10, and we maintain that position here. See FWD 56–59.” slip op. at 26
