      “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).

      “We agree with Petitioner that the term “3D slices” has no apparent connection to the phrase “direct volume rendering.” Patent Owner’s argument appears to be that DVR “requires an image of the entire anatomical volume that is neither feature-specific nor segmented, [which] would seemingly require that all inner layers be displayed.” Reply 4; see Sur-reply 6–10 (not disputing Petitioner’s characterization). But, as Petitioner notes, the specification directly undermines this by teaching “display [of] a slice of the 3D data instead of a volume of the 3D data.” See Reply 4 n.2 (quoting Ex. 1001, 5:34–35). In other words, to the extent DVR would depict an image of the entire anatomical volume, displaying 3D slices “instead of a volume of the 3D data” implies the opposite of DVR. Even if “3D slices” somehow implied DVR, Patent Owner’s position is still untenable. Claim 1 does not recite “3D slices.” Instead, claim 1 recites “3D data” and “inner layers.” Ex. 1001, 18:54–65. Patent Owner fails to clarify the relationship between “slices,” “3D data,” and “layers,” and its expert even admits that slices and layers are two different things. See PO Resp. 13; Ex. 1022, 32:7–16 (agreeing that the words “slice” and “layer” are not “synonyms”), cited in Reply 4. We also agree with Petitioner that dependent claim 3 distinguishes slices and layers by reciting “slices of the projected inner layer.” Reply 4 (quoting Ex. 1001, 19:3–10). Thus, even if 3D slices somehow implied DVR, the language of claim 1 does not support limiting the claim this way.” slip op. at 12

    • Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedDecided for petitioner

      “The determination of whether a document was publicly accessible “involves a case-by-case inquiry into the facts and circumstances surrounding the reference’s disclosure to members of the public.” Medtronic, Inc. v. Barry, 891 F.3d 1368, 1380 (Fed. Cir. 2018). For instance, courts routinely rely on the Wayback Machine to determine when a reference was first made available to the public. Valve Corp. v. Ironburg Inventions Ltd., 8 F.4th 1364, 1374 (Fed. Cir. 2021) (“District courts have taken judicial notice of the contents of webpages available through the Wayback Machine ‘as facts that can be accurately and readily determined from sources whose accuracy cannot reasonably be questioned.’”). We disagree with Patent Owner’s argument that “Medivis cannot rely on additional prior art”—Exhibits 1023 and 1024—“that was submitted after its Petition to carry its burden without leave from the Board.” Sur-reply 4. As Patent Owner did not file a motion to exclude these exhibits, we decline Patent Owner’s invitation to disregard them. We also find Petitioner’s Reply argument proper because it directly responds to Patent Owner’s contention that Petitioner did not prove the public accessibility of Amira. See Chamberlain Grp., Inc. v. One World Techs., Inc., 944 F.3d, 919, 925 on issues previously raised.”). Petitioner’s Reply argument appropriately elaborates on the Petition’s contention that Amira was publicly accessible. Patent Owner also does not dispute the substance of Petitioner’s evidence. For example, Patent Owner does not address the substance of Mr. Frank-White’s declaration. We find that this evidence, including Mr. Frank- White’s declaration testimony, persuasively supports the public availability of Amira as of the date shown in the Wayback Machine URL. See Ex. 1024.” slip op. at 22

      “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.

      “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

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).

      “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.

      “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

Also, there is no evidence that the recited quick-connect system is complex, even considering Patent Owner’s alleged understanding of it. Rather, Dr. Pratt testifies that many different types of connectors, whether they require alignment or not, were known. Ex. 1002 ¶¶ 54–58.

      “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. Magnet 606 is illustrated with its north pole located flush with the seat and facing toward the opening in bore 608. Massaging head 620 includes a shaft 621 having a cylindrical pocket 622 at the distal end. Located within the cylindrical pocket 622 is a magnet 624. Magnet 624 is positioned so that its south pole is located at the distal end of shaft 621. Accordingly, 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. Ex. 1001, 6:57–7:3. 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. 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 ¶ 56. Dr. Pratt also testifies that a POSITA would understand how to take into account certain variances, like runout. Ex. 2033, 25:3–17. 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.

Patent Owner also challenges motivation to combine Suzuki because it “is not directed to a pay-by-time, pay-per-view, or subscription distribution model, in which a content key grants access to content that different clients must individually decide to purchase in discrete units or increments.” Id. at 36–37. Petitioner responds that, because Peterka disclosed alternative embodiments that did not use sequence numbers or time stamps to identify EMM/ECM messages, one of ordinary skill would have been motivated specifically assign identifications to individual keys as taught in Suzuki. Reply 22 (citing Pet. 26). Petitioner also argues that whether Suzuki was directed to unpurchased content was irrelevant, because Suzuki is cited to show multiple key responses were conventional. Id. at 19–20. Patent Owner does not otherwise specifically address the issue of motivation to combine Peterka, Suzuki, and Bocharov. See generally PO Resp. Nonetheless the burden remains on Petitioner to demonstrate unpatentability. See Dynamic Drinkware, 800 F.3d at 1378.

      “We agree with Petitioner that the substitute claims are broadening. Because the amended wording only requires the key request to be made “in response to detecting” the boundary, rather than “ahead of” the boundary, the request can occur before or after the boundary. This is not a fanciful or unlikely possibility — such delayed requests are specifically contemplated by the ’178 patent: [I]f the packager 104 is unable to obtain a new content encryption key from the WFM 102 prior to the expiration of the current content encryption key, the packager 104 will continue to use the current content encryption key until such time as it is able to obtain a new key from the WFM 102. Ex. 1001, 6:32–37. It should be noted that the fixed period duration for key rotation may be viewed as a "target" period, as the packager 104 may not expire a key on the exact boundary. Ex. 1001, 8:9–11. The key expiration time from the WFM 102 may be viewed as a "suggested" expiration time, as the packager 104 may not be able to expire the key at the exact specified time.” slip op. at 56
