RulingsFinal written decision- Skill levelSkill level petitioner adoptedDecided for petitioner
“In the Response, Patent Owner states that it “does not dispute” the definition of one of ordinary skill in the art proposed by Petitioner, but Patent Owner “reserves the right to address [the definition] should new issues materialize.” PO Resp. 6. Patent Owner did not address this issue in the Sur-reply. As noted in the Decision on Institution, Petitioner’s proposed definition appears generally consistent with the record, including the prior art. See Dec. Inst. 8 (citing In re GPAC Inc., 57 F.3d at 1579). We remove the phrase “at least” in both listed options, however, as that phrase adds ambiguity. Further, Patent Owner has not argued at trial that Petitioner’s proposal for the level of ordinary skill leads to an improper understanding of how a skilled artisan would have understood either the challenged patent or the prior art. In the analysis below, we continue to apply the level of ordinary skill in the art adopted in the Decision on Institution, as proposed by Petitioner.” slip op. at 9

“Network LLC, 929 F.3d 1350, 1357 (Fed. Cir. 2019). At first glance, the language of the limitation at issue—which, again, recites “the compressed air and the operative fluid mix together in said mixing chamber to form the fluid dispersion”—would seem to require the “fluid dispersion” (under the stipulated construction) to be fully formed in the “mixing chamber.” In other words, the language of the limitation alone would seem to support Patent Owner’s proposed construction for the “form the fluid dispersion” limitation. But the claim construction analysis does not end with consideration of the claim language alone. Next, we turn to the Specification. The Federal Circuit has said that the specification “is the single best guide to the meaning of a disputed term.” Phillips, 415 F.3d at 1315 (quoting Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996)). Here, the discussion in the Specification of precisely the same language as in the limitation at issue strongly supports that “to form a fluid dispersion” in the limitation at issue requires only initial mixing of the compressed air and operative fluid in the mixing chamber, with further “formation” of the ”fluid dispersion” occurring downstream of the mixing chamber: More importantly, the “predetermined amount” of compressed air and the “preselected amount” of the operable fluid are initially mixed together in the mixing chamber 226 to form a fluid dispersion. The diffusion chamber 112" is further structured to facilitate the formation of a plurality of substantially uniform droplets, as defined hereinabove, in the fluid dispersion prior to discharge from the diffusion chamber 112" through discharge port 132. Ex. 1001, 10:62–11:2 (emphasis added) (discussing Figure 6), quoted, in part, at Pet. Reply 6–710; see also Ex. 1001, 5:64–6:4 (same language, except without double primes, in a discussion of Figures 1 and 2). To be sure, certain passages in the Specification could be read to indicate that a “fluid dispersion” must be fully formed in the “mixing chamber.” See, e.g., Ex. 1001, 6:11–12 (“More in particular, the suppression chamber 232 receives the fluid dispersion from the mixing chamber 226.”); see also id. at 7:22–33, 11:39–52 (both implying that a “fluid dispersion” is formed in the mixing chamber). But the passage block quoted directly above (and the similar one bridging columns 5 and 6) more directly addresses the issue at hand—i.e., the scope of “form the fluid dispersion”—by using the same” slip op. at 13

“As an initial matter, the record here does not support any sound basis to disregard the entirety of Dr. Micklow’s Declaration for allegedly not reviewing the parties’ claim constructions. See Pet. Reply 2 (citing Ex. 1046, 115:15–18). Contrary to Petitioner’s argument, in the cited discussion, Dr. Micklow does not indicate that he applied an incorrect understanding of a claim term. Cf. Cordis Corp. v. Bos. Sci. Corp., 658 F.3d 1347, 1357–58 (Fed. Cir. 2011) (disregarding testimony “based on an incorrect understanding of the claim construction”), cited at Pet. Reply 1. Instead, we read Dr. Micklow’s testimony as clarifying that he was not involved in claim construction at all and that, as stated, he “made [his] opinions based on what [he] read in the patents.” Ex. 1046, 112:11–12; see also id. at 115:15–18 (“I don’t know if I would even apply claim construction.

“To satisfy its burden of proving obviousness, a petitioner cannot employ mere conclusory statements. The petitioner must instead articulate specific reasoning, based on evidence of record, to support the legal conclusion of obviousness.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1380 (Fed. Cir. 2016); TriVascular, Inc. v. Samuels, 812 F.3d 1056, 1066 (Fed. Cir. 2016) (“Although the KSR test is flexible, the Board ‘must still be careful not to allow hindsight reconstruction of references . . . without any explanation as to how or why the references would be combined to produce the claimed invention.’”) (citation omitted). Based on the complete record, we agree with Patent Owner that “Petitioner’s asserted motivation boils down to the conclusory statement that given Goubet and Kaiser, ‘it was well known in the field at the time of the invention that droplets of greater uniformity result in uniform droplet evaporation.’” PO Resp. 31 (quoting Pet. 59). We agree with Patent Owner that Petitioner’s discussion of the alleged reasons to combine (Pet. 59) is insufficient to support the proposed combination here. See Magnum Oil, 829 F.3d at 1380. Specifically, we are not persuaded that Kaiser’s teachings—which relate to combustion (Ex. 1014 at 43)—would have led one of ordinary skill in the art to the proposed modifications, which would allegedly “improve the smoothness (i.e., less harsh) of the aroma generated as the oil droplets evaporate in the surrounding airspace.” See Pet. 59 (emphasis added); White Pet. Decl. ¶ 251 (same); see PO Resp. 32 (“Rather, Dr. White merely describes the ability to achieve the effect as in the claimed patent, not why a [person of ordinary skill in the art] would look to the field of electrospray injection and combustion in mesoscale power-generation systems, using high-voltage electric fields to generate charged fuel droplets for controlled combustion in catalytic micro-combustors when considering atomization for scents.”). For these reasons, we determine, in light of the complete record, that Petitioner has not shown by a preponderance of the evidence that one of ordinary skill in the art at the time of the invention would have had reason to combine Goubet and Kaiser, as proposed. slip op. at 32

“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.

“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

“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

“Appeals for the Federal Circuit. The court issued its decision in Stryker Corp. v. OsteoMed LLC, No. 2023-1925, 2025 WL 2814019 (Fed. Cir. Oct. 3, 2025) (“Stryker”) (Paper 49),1 affirming-in-part, reversing-in-part, vacating and remanding-in-part our Final Written Decision (Paper 46) for further proceedings. In its opinion, the Federal Circuit reversed our finding of no anticipation as to independent claims 1 and 11 of U.S. Patent No. 8,529,608 B2 (“the ’608 patent,” Ex. 1001), and vacated and remanded for further proceedings to evaluate whether dependent claims 2–6, 8–10, 12–14, and 17 (the “Remanded Claims”) are similarly unpatentable in view of Petitioner’s challenges relying on the Slater reference. Stryker, slip op. at 14–15. We have jurisdiction under 35 U.S.C. § 6. We issue this Final Written Decision on Remand pursuant to 35 U.S.C. §§ 144, 318 and 37 C.F.R. § 42.73 in an inter partes review involving Stryker Corporation and Wright Medical Technology, Inc. (collectively, “Petitioner”) and OsteoMed LLC (“Patent Owner”). For the reasons discussed below, after considering the entirety of the record in light of the Federal Circuit’s directives in Stryker, we find by a preponderance of the evidence that claims 6, 8–10, 14, and 17 are unpatentable. We also conclude that Petitioner has not demonstrated, by a preponderance of the evidence, that claims 2–5, 12, and 13 are unpatentable.” slip op. at 2

“Accordingly, for the same reasons expressed by our previous decision addressing claim 8 of the ’085 patent, and the court’s analysis in Stryker, we conclude that Slater does not anticipate claims 2–5, 12, and 13 of the ’608 patent because Slater deliberately describes a variable angle hole that lacks a single predetermined angle—that is, Slater describes a transfixation screw hole that does not have a central axis defining the trajectory.” slip op. at 13

Pet. 37–39; Ex. 1002 ¶¶ 161–169. Specifically, Petitioner contends that configuring Slater’s transfixation screw hole (claim 6) or at least one of Slater’s attachment points (claim 8) as a threaded screw hole to lockably engage the head of a locking screw would have been an obvious design choice “because locking screws ‘provide a high resistance to shear or torsional forces’ and reduce the incidence of screw loosening.” Pet. 39 (quoting Ex. 1009, 1:57–58); Ex. 1009, 1:46–48; Ex. 1002 ¶¶ 162– 163. Petitioner otherwise relies on its anticipation analysis for claim 1 discussed above. Pet. 37. Patent Owner raised no separate argument regarding the patentability of claims 6 and 8, instead relying solely on its argument that Slater does not anticipate independent claim 1, on which claims 6 and 8 depend. PO Resp. 46; Reply 4 (“Patent Owner does not challenge the combination of Slater and Weaver for claims 6 and 8.”). We have reviewed Petitioner’s arguments and evidence as to the undisputed limitations of claims 6 and 8 and find that Petitioner establishes that the combination of Slater and Weaver discloses all of the limitations of claims 6 and 8, and that one of ordinary skill in the art would have been motivated to combine Slater and Weaver for the reasons provided by Petitioner. We adopt Petitioner’s arguments and evidence as to these limitations as our own. See Pet. 37–39.” slip op. at 19

On remand, claims 6, 8, 9, and 13 were held unpatentable; claims 2–5, 11, and 12 were not shown unpatentable because Slater lacks the claimed central axis.
