      “independent claim 8 would have been obvious for the reasons set forth in its petition in the 791-IPR. See id. at 1 (stating the present Petition maintains the same grounds set forth in IPR2024-00791). As explained in our Final Written Decision (Ex. 3001) in the 791-IPR issued concurrently, Petitioner did not show by a preponderance of the evidence that independent claim 8 would have been obvious over Toyama under any of Petitioner’s three alternative arguments. None of Petitioner’s arguments set forth in the present Petition, including the arguments directed to claim 10, remedy the deficiencies regarding its base claim 8.

Pet. 17. In our Decision on Institution, we interpreted Petitioner’s position to be that no claim term of the ’581 patent requires express construction, and Petitioner did not disagree with this understanding during trial. Patent Owner agreed that no claim term required construction beyond its plain and ordinary meaning. PO Resp. 6.

      “the output conductor of a battery cell appears “simple” and that the proposed modification to Brown may be one of a small set of possible options. But that does not remove Petitioner’s obligation to explain why a person of ordinary skill in the art would have had some reason to make the modification to the prior art that has been proposed. Requiring a petitioner to articulate a reason to modify the prior art guards against hindsight evaluation of a modification which may only appear obvious after the fact. For this reason, the Supreme Court has noted that “there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness,” and that “[t]o facilitate review, this analysis should be made explicit.” See KSR, 550 U.S. at 418 (quoting In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)). Here, after evaluating the entirety of the factual record adduced at trial, we cannot conclude that Petitioner has set forth a sufficiently supported reason why a person of ordinary skill in the art would have modified Brown. First, we agree with Patent Owner that Petitioner’s articulated goal of maximizing the volume of active material in the cell is undercut by the modification it proposes. As Petitioner’s expert Mr. Juzkow admitted, relocating Brown’s output conductor to the bottom of the cell would reduce the volume available for active material by approximately one percent. While we do not disregard Mr. Juzkow’s subsequent testimony that other modifications to Brown’s cell (such as removal of the central screw cavity) could compensate for this loss in volume, the fact remains that Petitioner did not propose these additional modifications in the Petition. It is incumbent on Petitioner to set forth all modifications to the prior art it plans to rely on, and justify why a person of ordinary skill in the art would have had reason to make them, so that we may fully evaluate whether it would have been obvious to do so. In any event, even if we were to accept Mr. Juzkow’s late assertion of other modifications that could be used to compensate for the loss in volume of active material, the fact remains that it is these other modifications that would be serving the motivation proposed by Petitioner of maximizing the volume of active material; relocating the output conductor would have no positive effect towards this modification. Thus, we conclude that Petitioner’s expressed motivation of maximizing active material volume has no rational relationship to the modification of Brown that is central to its Petition, of relocating the output conductor from the side of the casing to the bottom.” slip op. at 24

Original claims 1–12 are no longer at issue in this proceeding, having been canceled and replaced by substitute claims 14–25 via a granted Motion to Amend in IPR2020-01211. And we have found that Petitioner has not established by a preponderance of 13 Although not raised in briefing by either party, we have also evaluated whether estoppel under 37 C.F.R. § 42.73(d)(3)(i) would require a finding of unpatentability of claim 13 in light of our prior determination in IPR2020- 01211 that claims 1–12 are unpatentable. See 37 C.F.R. § 42.73(d)(3)(i) (“A patent applicant or owner is precluded from . . . obtaining in any patent: A claim that is not patentably distinct from a finally refused or canceled claim.”). We conclude that it does not. The Board has previously held that defending the patentability of a previously-issued claim in an inter partes review does not qualify as “obtaining in a patent” that claim, and therefore patent owner estoppel does not apply in this situation. See Apple Inc. v. ContentGuard Holdings, Inc., IPR2015-00458, Paper 9, 8 (PTAB July 15, 2015). the evidence that claim 13 is unpatentable.

See Innogenetics, N.V. v. Abbott Labs., 512 F.3d 1363, 1374 (Fed. Cir. 2008).

Pet. Reply 7. Petitioner’s argument and Dr. Gale’s that does not apprise us of why a POSA would have modified Zou I with access holes that would operate as separate sample inlets for each sample lane as required by the claims of the ’708 patent. Here, Petitioner attempts to imbue a POSA with the knowledge of the claimed invention, when no prior art reference, references of record, or other evidence conveys or suggests that knowledge. Petitioner’s argument that a POSA would have modified Zou I in this way appears to be premised on Petitioner’s knowledge of the ’708 patent disclosure. This is improper hindsight reasoning. Petitioner needed to explain what would have led a POSA at the time of the invention to consider modifying Zou I to include a separate sample inlet with each sample lane. Petitioner failed to provide such an explanation. See W.L. Gore & Assoc., Inc. v. Garlock, Inc., 721 F.2d 1540, 1553 (Fed.

In order to demonstrate that the challenged claims are obvious, a petitioner must demonstrate “that a skilled artisan would have been motivated to combine the teachings of the prior art references to achieve the claimed invention, and that the skilled artisan would have had a reasonable expectation of success in doing so.” ActiveVideo Networks, Inc. v.

      “At best, the evidence establishes that reducing protrusions in Law’s backside coating may result in the surface approaching a Gaussian distribution (namely, a skew of 0 and a kurtosis of 3). See Ex. 1003 ¶ 171 (“By reducing the number of peaks the overall surface may become closer to a Gaussian distribution, which by definition has a skew of zero.” (emphasis added)), ¶ 174 (“As the frequency of large protrusions is reduced, the skew of the backcoat surface approaches 0 and the kurtosis becomes closer to 3.” (emphases added)). There is no evidence of record, however, that establishes the skew and kurtosis values of Law’s backside coating before reducing the protrusions as Petitioner proposes. While it is possible that reducing Law’s protrusions could result in skew and kurtosis values within the claimed range, it is also possible that reducing the protrusions could result in a surface that approaches a Gaussian distribution but still has a skew above 0.5 and a kurtosis above 4.0.

Thus, even if reducing the protrusions on Law’s backside coating caused the surface to approach a Gaussian distribution, that is not sufficient to establish that it necessarily results in a skew less than about 0.5 and a kurtosis less than about 4.0 as claimed. The skew and kurtosis values recited in claims 1 and 20 are not simply properties possessed by any backside coating that otherwise satisfies the structural limitations. Instead, they are recited as limitations on which magnetic recording media fall within the scope of the claims. The evidence of record does not establish that reducing the protrusions in Law’s backside coating, as taught by Sasaki, “would have naturally led to a backside surface having a skew less than about 0.5 and a kurtosis less than about 4.0” as Petitioner contends. Pet. 45. Accordingly, on the record before us, we find that Petitioner has not established that claims 1 and 20 would have been obvious over the combined teachings of Law and Sasaki.” slip op. at 21

      “thermal inefficiencies of the Hon ’043 atomizer are based on Dr. Sturges’s hypothesis “that a ‘large majority of the spray would . . . never touch the heating wire,’” noting that Dr. Sturges assumes an insignificant amount of liquid would contact the heating element based on the dimensions of the figures in Hon ’043. PO Resp. 23 (citing Ex. 2015 ¶ 62 n.2). Petitioner, however, does not provide adequate explanation as to why a person having ordinary skill in the art would think that to be the case. In reaching that determination, we credit Mr. Meyst’s testimony over that of Dr. Sturges. For example, Mr. Meyst identified a number of factors that would affect the determination of the percentage of entrained droplets that contact the wire in the Hon ’043 atomizer, stating that, [w]hile it is true that some liquid droplets will not touch the heater, there is no way to know what percentage will come into direct contact without knowing a number of other factors, such as the heater’s dimensions, the cavity’s dimensions, the size of the ejection holes, and the spray pattern. A person of ordinary skill would have understood these factors, and would have made selections that would result in most of the liquid coming into direct contact with the heating element. For example, Hon ’043 discloses that the ejection holes may be “long” or [“]short,” may employ a “slot structure” or a “circular hole structure” ranging from 0.1 mm to 1.3 mm, and that “single” or “multiple” holes may be used. A skilled person could have calculated or used commercially available Computational Fluid Dynamics software such as FLUENT to model the path of droplets ejected from the ejection holes and focus them at the heating element. Ex. 2030 ¶ 99 (internal citations omitted). We are unable to discern, from any of the portions of Dr. Sturges’s testimony cited by Petitioner, any calculations to determine how factors such as the speed and pressure of the airstream, and the rate of change of pressure of the airstream as it travels through the ejection holes and into the atomization chamber, would affect the dispersion of the droplets ejected from the ejection holes towards the heating wire in Hon ’043. Reply 7–8 (citing Ex. 1026 ¶¶ 7–11; Ex. 1039 ¶ 52). Dr. Sturges also presents a slip stream example to argue that the vast majority of the flow slips past the heating wire (Ex. 1026 ¶ 10), but Patent Owner argues that this example is not applicable to the ejected liquid droplets disclosed in Hon ’043 (citing Ex. 2030 ¶¶102–106), and that Dr. Sturges confirmed this in his deposition (citing Ex. 2031, 106:14–107:10). PO Resp. 26. In light of the variables that can affect how the droplets could disperse upon ejection from the ejection holes, Petitioner has not explained adequately why a person having ordinary skill in the art would understand that only a small amount of droplets would contact Hon ’043’s heating wire and that the atomization described in Hon ’043 is inefficient.” slip op. at 16

      “modification of Hon ’043 leave an analytical gap that does not sufficiently apprise us of why one of ordinary skill in the art would have modified Hon ’043 with Whittemore’s wire-wrapped wick. Petitioner’s and Dr. Sturges’s assertions that a person having ordinary skill in the art would have been motivated to modify Hon ’043 based on thermodynamics principles do not adequately address why a person having ordinary skill would have wanted to provide more efficient heating in the Hon ’043 electronic cigarette. In an obviousness determination, we must avoid analyzing the prior art through the prism of hindsight. Instead, we must “cast the mind back to the time the invention was made” and “occupy the mind of one skilled in the art who is presented with only the references, and who is normally guided by then-accepted wisdom in the art.” W.L.

Cir. 2008) (“We must still be careful not to allow hindsight reconstruction of the references to reach the claimed invention without any explanation as to how or why the references would be combined to produce the claimed invention.”)). Here, we interpret Petitioner’s position as an attempt to imbue one of ordinary skill in the art with knowledge of the claimed invention, without adequately demonstrating that a prior art reference, references of record, or other evidence conveys or suggests that knowledge. Petitioner’s proposed rationale relies upon general and conclusory statements from Dr. Sturges regarding thermodynamics that are not sufficiently supported in the record, and instead appear to be based on impermissible use of hindsight after review of the ’548 patent, rather than on a supported reason to modify the heating configuration in Hon ’043’s atomizer. See KSR, 550 U.S. at 421 (stating that the fact finder must be aware “of the distortion caused by hindsight bias and must be cautious of arguments reliant upon ex post reasoning”). In order to establish a motivation to combine the references, Petitioner needed to explain sufficiently what would have led a person of ordinary skill in the art at the time of the invention to consider modifying the Hon ’043 atomizer to include a “heating wire coil wound on” the porous component, on the first section of the porous component, or on the fiber member as recited in claims 1–14, and Petitioner failed to provide such an explanation.” slip op. at 18

As Patent Owner points out, Hüthwohl does not provide details regarding the SCR catalyst or the wall-flow filter used in its system. PO Resp. 36–37. In that regard, Dr. Harold characterized Hüthwohl as a “proof of concept” that would lead a person of ordinary skill in the art to conduct testing. PO Resp. 37; Ex. 2025, 205:5–9. Given the vague nature of Hüthwohl’s disclosure, we view Hüthwohl as simply providing incentive “to explore a new technology or general approach that seemed to be a promising field of experimentation,” and agree with Patent Owner that Hüthwohl, at best, provides “only general guidance as to the particular form of the claimed invention or how to achieve it.” Procter & Gamble, 566 F.3d at 997; PO Resp. 37. Thus, upon reviewing Hüthwohl, a person of ordinary skill in the art would still have had to identify an acceptable combination of an SCR catalyst and wall flow filter, decide how much SCR catalyst to apply to the filter, and determine if the wall flow filter coated with the SCR catalyst provided substantial NOx reduction and integrated NOx and particulate removal efficiency while also catalyzing the oxidation of soot.” slip op. at 30

Dr. Harold also testified that the only way to know how much of each reaction will occur is by “throwing everything together and measuring the outcome.” Id. As such, the evidence of record suggests that a person of ordinary skill in the art would not have known the result of introducing Speronello’s catalyst and NH3 into the highly oxidizing environment of any soot filter, but instead would have had to conduct testing to understand how such a system would perform.
