“referring to the same direction as the separation of the “upper chamber” and “lower chamber” (vertically in both Figure 6 of the challenged patent and Figure 1 of Goubet), we turn back now to Petitioner’s discussion of clause 1F, which includes the limitation at issue. There, Petitioner does not discuss why the “diffusion assembly” is allegedly “disposed between” the “upper chamber” and “lower chamber,” but instead, Petitioner discusses why a component of the “diffusion assembly”—the “atomizer assembly”—is allegedly “disposed between” the “upper chamber” and “lower chamber”: Pet. 39. In the end, we need not assess whether the “atomizer assembly” identified by Petitioner is “disposed between” the “upper chamber” and “lower chamber” under the proper construction of that term (which, again, we need not and do not determine here) because the “disposed between” limitation does not involve the “atomizer assembly.” Instead, we find that, by failing to address why the identified “diffusion assembly” is “disposed between” the identified “upper chamber” and “lower chamber,” Petitioner has failed to provide persuasive evidence that Goubet discloses or suggests the “disposed between” limitation. Pet. 38–39 (discussing the claim language “said diffusion assembly is disposed between said upper chamber and said lower chamber” but only discussing the location of the “atomizer assembly”); see 35 U.S.C. § 316(e) (“In an inter partes review . . . , the petitioner shall have the burden of proving a proposition of unpatentability by a preponderance of the evidence.”).

“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).

“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

“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

“that Boerjes alone teaches or suggests limitation 1(h) by a preponderance of the evidence. Although the Petition is persuasive that Boerjes allows a user to “identify areas that need replacing, such as ‘a margin line’ to be removed, ‘areas of poor margin preparation,’ and ‘holes or areas of incomplete scan[s],’” and that the user can identify regions of a prepared tooth surface requiring additional preparations and “supplemental scanning” (Pet. 32 (citing Ex. 1004 ¶¶ 189, 193, 196)), Boerjes is silent with respect to replacing at least a portion of the removed surface portion of the model using the received second scan data of the patient’s teeth, per claim 1. Boerjes certainly contemplates the re-scanning of the dentition, but does not assert partial insertion of new data into an existing 3D model. We acknowledge that Petitioner has argued (Pet. 43–44) that Boerjes’ Figure 4 and paragraph 144 of Boerjes teach partial replacement, but we are persuaded that those disclosures suggest total replacement and not partial replacement. The reference to “supplemented or replaced with new scan data” (Ex. 1004 ¶ 199) does not necessarily teach or suggest partial scanning, as Petitioner has argued. Additionally, Petitioner has argued (Pet. “combining historical three-dimensional data” (quoting Ex. 1004 ¶¶ 139, 144, 163), would have suggested to ordinarily skilled artisans that “Boerjes would be used to replace at least a portion of the model with the new scan data. Id. at 45 (citing Ex. 1003 ¶ 112). These disclosures are, however, applicable to scans that create complete replacement as well as partial replacement. We remain persuaded that Boerjes does not teach partial scans used to obtain partial replacement. Even under the “comprising” language of claim 1, for example, the complete replacement of a 3D model cannot teach or suggest “replacing at least a portion of the removed surface portion” without repudiating the language of the claim by making a portion be the entire model. Even if, as Petitioner asserts, “removing portions of a virtual model has been a well-known and routine technique in 3D modeling,” and the “process of replacing a user-identified portion would have been well within the skills of a POSITA” (Pet. 35), the disclosure of Boerjes does not teach or suggest such processes. Although Boerjes allows for the possibility that portions of a model can be identified as needing replacement or supplementation, it does not disclose the partial replacement required by the instant, independent claims. Boerjes’s actual disclosure details that supplemental scanning is used to compensate for an inadequate scan, but such supplemental scanning is not disclosed to be used to stitch together before-and-after models that have undergone an intervening physical change.” slip op. at 15

“We disagree with Patent Owner that a person of ordinary skill in the art would have understood that limitation 1.2 must be performed before limitations 1.3 or 1.4. See Ex. 1001, 35:21–24. See Interactive Gift Exp., Inc. v. Compuserve Inc., 256 F.3d 1323, 1342 (Fed. Cir. 2001) (“Unless the steps of a method actually recite an order, the steps are not ordinarily construed to require one.” (citing Loral Fairchild Corp. v. Sony Corp., 181 F.3d 1313, 1322 (Fed. Cir. 1999)). The evidence suggests that a “target printer” is any printer that is ultimately selected for fabricating the object, and such a printer could send its configuration information either before or after that determination is made in limitation 1.2. This interpretation does not render the word “target” meaningless. At some point, a printer must be determined to be the target printer, which is the one intended to ultimately fabricate the three-dimensional object. But the target printer still exists, and is capable of being queried, before that determination is made. We find the examples in the ’774 patent pertinent to this question. The ’774 patent states that “the target printer may include more than one printer.” Ex. 1001, 18:66–67. In discussing the step of “query target printer for properties 306” (Fig. 3A), the ’774 patent states that “[i]n one aspect, numerous queries are sent to numerous printers, e.g., for use in selecting one or more of the printers as the target printer.” Id. at 19:8–10. Alternatively, “the query is sent to a printer that is not necessarily the target printer as described herein, e.g., when the query or information received from a response to the query is used for the selection of the target printer.” Id. at 19:11–14. Importantly, the second embodiment states that the queried printer “is not necessarily the target printer,” suggesting that the queried printer could be the target printer even before it is determined to be such. Id. at 19:11–12 (emphasis added). Based on the evidence of record, a person of ordinary skill in the art would have understood that the “target printer” can be determined after the query recited in limitation 1.3 or the reception of configuration information recited in limitation 1.4. Thus, the evidence does not impose an ordering between limitations 1.2 and 1.3 or between limitations 1.2 and 1.4. The evidence also does not support Patent Owner’s argument that the two reverse-order examples in the ’774 patent are unclaimed embodiments.” slip op. at 10

In particular, Cleveland discloses that “the coextruded layer of copolyester (irrespective of which side of the substrate the layer is disposed) is of a total coat weight of between about 10 and about 40 lb/3000 ft2 in any combination of between about 80/20 to 20/80 parts by weight of Ecoflex to Biomax,” of which “a total coat weight of 25 lb/3000 ft2 is preferred.” Ex. 1005 ¶ 32. As disclosed, Cleveland’s total coat weight range of 10–40 lb/3000 ft2 falls almost entirely within the claimed range, and the preferred total coat weight of 25 lb/3000 ft2 falls squarely within the claimed range.

“We begin with the claim language in view of the Specification, which weighs heavily against Patent Owner’s position that we should rewrite “computer system” as narrowly referring to a “computing device.” PO Resp. 24. As Petitioner notes, the ’872 patent’s Specification uses “computer system” to refer to a wide range of equipment, from a component of a computing device, to a whole computing device, to a collection of computing devices. Reply 9–10 (citing Ex. 1001, 4:5–8, 11:15–18, 16:50–55). In one example, the Specification refers to “one or more other computer systems (e.g., protected network devices 136).” Ex. 1001, 18:52–53. Thus, the Specification lists “protected network devices 136” as only an example of “other computer systems,” demonstrating that “computer systems” refers to things other than protected network devices. Although Patent Owner may be correct that this passage more than a single computing device,” we find that other disclosures in the ’872 patent do. Specifically, the Specification uses the language “distributed computer system” when referring to numerous components, including “protected network devices” and an “IDS/IPS system.” Ex. 1001, 3:26–28; Reply 10. In addition to showing that a “computer system” is not limited to a single computing device, this conveys that a “computer system” according to the ’872 patent can include an IDS/IPS.” slip op. at 14

“Based on our review of the complete record, we find Petitioner’s arguments and evidence to be more persuasive. Patent Owner does not dispute Petitioner’s argument and evidence that capturing detailed information like Goel’s activity sources, activity targets, and association was recognized as enhancing threat analysis. Pet. 44 (citing Ex. 1003 ¶ 79); see PO Resp. 55–59; Sur-Reply 15–17. Additionally, contrary to Patent Owner’s suggestion, we find that the Petition does not propose incorporating Goel’s kernel hooks into Capalik’s system. See Pet. 41–46. Patent Owner contends that the Petition’s reference to modifying Capalik by “adding lines of code” suggests implementing the code disclosed in Goel include kernel hooks. Id. Notwithstanding Patent Owner’s assertion otherwise, this is an unpersuasive bodily incorporation argument, as the Petition never says an ordinarily skilled artisan would have used the exact lines of code from Goel in Capalik. Rather, the Petition says that an ordinarily skilled artisan would have had sufficient skill to implement straightforward code modifications to identify activity sources, targets, and associations: a [person of ordinary skill in the art] would have understood that modifying Capalik’s system (e.g., Linux-based) to additionally monitor, identify, and store each individual activity of an attack including “activity sources, activity targets, and associations” would have required straightforward modifications to programs/code instructions, which would have been well-within the skillset of a [person of ordinary skill in the art]. Pet. 46. Patent Owner argues that Petitioner does not explain how an ordinarily skilled artisan would have modified Capalik without using kernel hooks. Sur-Reply 17. But Patent Owner does not cite any evidence to counter Dr. Jakobsson’s testimony that an ordinarily skilled artisan would have had the skill to apply Goel’s general teaching of identifying sources, targets, and associations to Capalik’s system. Ex. 1003 ¶ 182. On the whole, the evidence does not support Patent Owner’s position that the combination would have required substantially increased detection risk. Moreover, even if the combination would have somewhat increased detection risk, Petitioner persuades us that an ordinarily skilled artisan still would have had reason to combine the references teachings. Patent Owner’s allegations of increased detection risk do not negate the undisputed evidence that the combination would have provided the advantage of improved threat analysis. Pet. 44 (citing Ex. 1003 ¶¶ 175–182). Ultimately, Patent Owner’s that activity logging be undetectable.” PO Resp. 56 (emphasis added) (citing Ex. 1004 ¶ 6). This exaggerates Capalik’s disclosure. Although the cited paragraph suggests that certain systems unfortunately may be detectable by some users, it does not convey that it is a requirement for the system to be categorically undetectable. See Ex. 1004 ¶ 6.8 In sum, Petitioner persuades us by a preponderance of the evidence that it would have been obvious to modify Capalik “to identify and store unauthorized activities including the activity source, activity target, and association of each activity.” Pet. 41–46; PO Resp. 55–59; Reply 20–22; Sur-Reply 15–17.” slip op. at 47
- Obviousness (§103) › Objective indicia / secondary considerations › NexusObjective indicia no nexusDecided for patent owner
“arguments and evidence, we determine that Patent Owner fails to sufficiently show a nexus between any of its objective indicia evidence and the claimed invention. See Fox Factory, Inc. v. SRAM, LLC, 944 F.3d 1366, 1373 (Fed. Cir. 2019) (“The patentee bears the burden of showing that a nexus exists”). A showing of sufficient nexus is required to establish that the evidence relied upon traces its basis to a novel element in the claim, not to something in the prior art. Institut Pasteur & Universite Pierre Et Marie Curie v. Focarino, 738 F.3d 1337, 1347 (Fed. Cir. 2013). Objective evidence that results from something that is not “both claimed and novel in the claim” lacks a nexus to the merits of the invention. In re Kao, 639 F.3d 1057, 1068 (Fed. Cir. 2011) (emphasis omitted). Thus, establishing nexus involves a showing that novel elements in the claim, not prior-art elements, account for the objective evidence of nonobviousness. Id. As discussed above, Petitioner shows that Capalik teaches all limitations of claim 1. Petitioner persuades us that none of claim 1’s elements individually nor any combination thereof is novel over Capalik’s disclosure. Accordingly, claim 1 is not novel over Capalik, which disproves Patent Owner’s assertion of nexus. PO Resp. 73–76. Moreover, even if claim 1 were novel, Patent Owner otherwise fails to show nexus for its commercial success, praise, or copying assertions. Patent Owner’s evidence does not show that Petitioner’s commercial product embodies claim 1. For example, we agree with Petitioner that Patent Owner “failed to analyze any meaningful detail regarding” how the Falcon Platform allegedly meets limitation 1(d). Reply 28–29.

“defined stoichiometry” (Ex. 2037, 527) but the word may also be a “generic term for phases . . . which may have a narrow or extended compositional stability range” (id.). The first glossary meaning is consistent with Patent Owner’s position. The second, broader, glossary meaning is consistent with Petitioner’s position. Some of the extrinsic sources before us support the broad definition, and some support the narrow definition. See PO Sur-Reply 3–4 (arguing that Dr. Miles admitted that various treatises distinguish intermetallic compounds from alloys and solid solutions). Thus, neither Dr. Miles or Dr. Raabe is “wrong scientifically” in how they use the term “intermetallic” in this proceeding. Id. at 2 (noting that Dr. Miles agreed that Dr. Raabe’s construction is not wrong scientifically). As explained below, however, only one of these meanings is appropriate here. To decide which possible meaning applies to the ’227 patent, we focus on the patent claims and specification. Claim 1 indicates that the intermetallic layer has a “mean composition” (emphasis added). Ex. 1001, 15:1–10. This indicates, albeit weakly, that iron composition across the layer may vary rather than having ordered stoichiometry—consistent with Petitioner’s position. The specification also indicates that “intermetallic alloying” is a possibility—again, consistent with Petitioner’s position. Ex. 1001, 2:47–50. Meanwhile, nothing in the ’227 specification explicitly (or implicitly) suggests that “intermetallic layer” must be limited to elements atomically joined with defined stoichiometry in an ordered crystal structure. We also find that Dr. Miles’s testimony regarding the meaning of “intermetallic” is more credible than Dr. Rabbe’s testimony. Dr. Rabbe, in deposition, stated that Figure 2 of the challenged patent “does not show a layer that meets [his] construction of intermetallic.” Ex. 1078, 129:21–24. The ’227 patent, however, states that Figure 2 includes an “Al-rich Intermetallic layer.” Ex. 1001, Fig. 2, 3:60–64 (“FIG 2. Illustrates a coating … which does not correspond to the invention. This succession of layers (interdiffusion layer and intermetallic layer) yields inferior results in resistance spot welding.”). Also, Dr. Raabe previously referred to a layer of Takagi as having “intermetallic phase layering and structure.” Pet. Reply 4 (citing Ex. 1076 ¶ 166; Ex ¶ 1075, 17) (emphasis omitted). Thus, Dr. Raabe’s construction of “intermetallic” for this proceeding does not fully account for the ’227 patent usage of the word “intermetallic” and does not fully account for Dr. Raabe’s prior usage of the word “intermetallic.” Patent Owner argues that Petitioner’s construction “erases the meaningful distinction” between the claimed layers. PO Resp. 11. Patent Owner further argues that Petitioner’s construction renders the word “intermetallic” superfluous because allowing the intermetallic layer to be “merely a multi-element alloy erases the meaningful distinction among these layers.” Id. We disagree. The word intermetallic serves to require that the layer be composed of two or more metals or a metal and a metalloid. The word intermetallic also serves as a label to differentiate each of the four claimed layers. For example, in claim 1, the word “intermetallic” is used much like the words “interdiffusion” and “intermediate” to give each of the four layers (each having differently mean compositions) different labels.” slip op. at 16
