      “record before us, we conclude that Petitioner proves by a preponderance of the evidence that each challenged claim of the ’811 patent is anticipated by Douglas and by Ganesh. Accordingly, we find that claims 1–7, 10, 13, 16, 18, and 19 of the ’811 patent are unpatentable. Moreover, we find that Patent Owner’s Revised Contingent Motion to Amend adds new matter in every proposed substitute claim, and, therefore, the motion is denied.” slip op. at 80

      “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. We apply that definition here, as it accords with the problems addressed in the prior art and the specification of the ’682 patent.” slip op. at 7

      “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

      “All other challenged claims require the “generating” and “assembling” operations because they depend from claims 1, 12, or 17. Petitioner does not allege that the additional references—Durante, Ma, Suzuki, Wanamaker, Heikens, Matthews, or Wilsher—teach or suggest the “temporal sequence of screen captures” recited in claim 1. Rather, Petitioner’s reasoning in the challenges to the dependent claims pertaining to the screen captures mirror the rationale presented in the independent claim.

Petitioner’s argument that Avellan teaches or suggests these operations in the grounds based on obviousness under 35 U.S.C. § 103 depend on the reasoning and insufficiently supported characterizations of Avellan in the challenges based on 35 U.S.C. § 102, as discussed above.

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. 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

See Pet. Reply 11. This argument does not satisfy Petitioner’s burden to provide articulated reasoning with some rational underpinning to support the conclusion of obviousness. See KSR, 550 U.S. at 419 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)). Petitioner does not explain which teaching of Kleppner a person of ordinary skill would have selected and combined with their knowledge of a rotation vector to yield the method of claim 1, or explain why a person of ordinary skill would have recognized based on Kleppner that estimating the angle between a rotation vector and gravity vector could be used to detect a vehicle turning. Nor does Petitioner respond to Patent Owner’s assertion that Kleppner provides no rationale for estimating an angle of alignment between a rotation vector and gravity vector as a way of detecting a vehicle turning.

      “question, based on factual findings. VidStream, 981 F.3d at 1063–64. Moreover, public accessibility is the touchstone in determining whether a reference is a printed publication and such depends on whether the reference was available to interested, ordinarily skilled persons exercising reasonable diligence, which is determined on a case-by-case basis. Id. at 1065. Particularly pertinent here is that “[w]hen there is an established publisher there is a presumption of public accessibility as of the publication date.” Id. Hulu (which cites VidStream on this issue) concerned, inter alia, whether certain asserted references were shown to be publicly available and could be considered as prior art. Hulu, 2021 WL 487622. Hulu holds that, although testimonial evidence is one way to prove public accessibility, there are also a variety of hallmarks of publication and other evidence that may be considered as a totality of the evidence to determine if an asserted reference was publicly accessible and prior art. Id. at *10–13, 21. 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.

      “To the extent Patent Owner contends that a person of ordinary skill in the art need not be defined as of the critical date, we disagree. Under Section 103, we must determine “if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains” (emphasis added). “Obviousness is determined from the vantage point of a hypothetical person having ordinary skill in the art to which the patent pertains.” In re Rouffet, 149 F.3d 1350, 1357 (Fed. Cir. 1998). Thus, we define the hypothetical person of ordinary skill in the art as of a time before the effective filing date. To the extent Patent Owner’s argument is that, to testify from the perspective of a person of ordinary skill in the art, one need not have been a person of ordinary skill in the art as of the critical date, we agree. Although one must at least possess ordinary skill in the art to testify from the perspective of a person of ordinary skill, [a]n expert need not have acquired that skill level prior to the time of the invention to be able to testify from the vantage point of a person of ordinary skill in the art. Rather, an expert can acquire the necessary skill level later and develop an understanding of what a person of ordinary skill knew at the time of the invention. Osseo Imaging, LLC v.

      “C. Claim Construction The parties agree that no claim terms require express construction. Pet. 10; Prelim. Resp. 2–4. Patent Owner, however, notes that, in related district court litigation, Petitioner has asserted that some claims terms are indefinite. Patent Owner argues that the Petition should be denied because Petitioner has taken inconsistent claim construction positions between the district court and the Board. Paper 14 at 1–3 (citing Tesla, Inc. v. Intellectual Ventures II LLC, IPR2025-00340, Paper 18 at 4 (PTAB Nov. 5, 2025) (informative); Revvo Techs., Inc. v. Cerebrum Sensor Techs., Inc., IPR2025-00632, Paper 20 at 4–5 (PTAB Nov. 3, 2025) (precedential)). Petitioner responds that, in the related district court litigation, the parties have narrowed the claim construction disputes and that Petitioner accords the plain and ordinary meaning to claim terms and no longer asserts that any claim term of the ’077 patent is indefinite. Paper 15 (citing, inter alia, Ex. 1126 (Defendants’ Responsive Claim Construction Brief)). The evidence supports Petitioner’s position because, in the related district court litigation, the defendants agree with the plaintiff (Patent Owner) that certain phrases in the ’077 patent claims should be given their “[p]lain and ordinary meaning” and are “not indefinite.” Ex. 1126, 6 (native page 1). Thus, the record does not show inconsistent claim construction positions that warrant denial under PTAB precedent. See Revvo, Paper 20 at 5 (addressing a situation in which a petitioner advances “different claim construction positions” in district court and at the PTAB). See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed.

Resp. 20. Petitioner, however, points out this change in the Petition and acknowledges that it is after the identified critical date of August 20, 2015. See Pet. 28. Thus, we do not understand Petitioner to be relying on Bharadwaj’s disclosure of subtracting m to determine length, as disclosed in the publication of the non-provisional application, as a prior art disclosure. We understand Petitioner to be relying on disclosures in Bharadwaj-Prov059 for prior art teachings for its obviousness contentions. Patent Owner does not appear to dispute that Bharadwaj-Prov59’s disclosures are prior art, arguing instead that it is improper to rely “on matters in Bharadwaj beyond ‘incorporation by reference’ of the Bharadwaj-Prov59.” See Prelim. Resp. 20–21. On this record, we determine that Bharadwaj-Prov59’s disclosures are prior art as of its June 2, 2015, filing date by virtue of its incorporation by reference into Bharadwaj, a published US patent application.
