“these drawbacks in a petition directed to a related patent, where Petitioner argued that “a significant portion of the available space within [Kobayashi’s] cell is reduced by the process of crimping the cell closed.” Id. at 46 (quoting Ex. 2008, 2–3). Patent Owner argues that “Petitioner fails to explain why the beaded-over Kobayashi housing Petitioner and its same expert disparaged in another petition would be used in the present combination of references proposed in this Petition.” Id. at 48. Patent Owner’s argument raises an issue about a tradeoff that a person of ordinary skill in the art might or might not have made: under Petitioner’s proposed combination of teachings, it may be that a person of ordinary skill in the art would have had to accept reduced internal volume, and the consequent reduction in energy capacity, as the price of avoiding short circuits. The question of whether this tradeoff existed and, if so, whether a person of ordinary skill in the art would have made the tradeoff is a factual issue best resolved on the full record to be developed at trial. Patent Owner also argues that a person of ordinary skill in the art would not have replaced Higuchi’s housing with Kobayashi’s to reduce the risk of short circuits. Prelim. Resp. 48–49. Patent Owner points to Petitioner’s arguments in a related case regarding claims 27 and 28 of U.S. Patent No. 11,024,905, where Petitioner argues that it would have been obvious to add Kubota’s insulation tape to Higuchi’s leads 11 and 12, and Patent Owner argues that a similar modification here “could reduce such risk Kobayashi’s housing.” Id. at 48–49 (citing Ex. 2042, 2–4). According to Patent Owner, if “Petitioner and its expert are correct that a [POSITA] would have been motivated to adhere an insulation strip to both sides of Higuchi’s lead, it would not be necessary to change Higuchi’s housing for Kobayashi’s beaded-over housing to reduce the risk of short circuits.” Id. at 49. The fact that the prior art may suggest that some combination of techniques is more desirable than, or otherwise preferred over, the combination on which Petitioner relies does not preclude a finding that the challenged claims would have been obvious over Petitioner’s proposed combination. See Bayer Healthcare Pharms., Inc. v. Watson Pharms., Inc., 713 F.3d 1369, 1376 (Fed. Cir. 2013) (quoting In re Fulton, 391 F.3d 1195, 1200 (Fed. Cir. 2004)). Thus, we have considered Patent Owner’s arguments, and although they cast doubt on Petitioner’s contentions and create a genuine issue of material fact, we are persuaded, on this record, that Petitioner provides sufficient reasoning with rational underpinning to support a motivation to combine the teachings of Higuchi and Kobayashi as proposed. Pet. 21–33. Specifically, Petitioner sufficiently establishes, for purposes of institution, that a POSITA would have had reason to modify Higuchi’s cell to use Kobayashi’s housing in order to reduce the risk that the cell would short circuit. Id. at 23–27. Whether Petitioner sufficiently establishes this issue to prove unpatentability is an issue we need not, and do not, resolve on this preliminary record. We invite the parties to develop these arguments further at trial, to the extent permitted under our rules.” slip op. at 20

To the extent that Kerry is seeking to disqualify Dr. Baldwin’s testimony in its entirety under Kyocera, we consider this to be a new argument that differs from Kerry’s initial argument that Dr. Baldwin’s testimony should be afforded little or no weight due to his lack of familiarity with the field of the ’304 patent. Because new arguments made for the first time in sur-reply are not permitted, we will only focus on Kerry’s initial challenge to the testimony of Dr. Baldwin. testimony, regardless of the subject of his particular opinions. It is clear that Dr. Baldwin has expertise in some areas of chemistry, while Dr. Milkowski’s experience is focused on other areas and emphasizes food chemistry. These differences in expertise may impact how we weigh the testimony of both witnesses, but that determination should be made in the context of a specific subject and based on the applicability of each witness’s background to the opinions. Therefore, we decline to adopt Kerry’s proposed approach of giving Dr. Baldwin’s testimony “little to no weight,” and instead will weigh the expertise of both witnesses in evaluating their testimony on specific areas of dispute, if necessary.” slip op. at 14

“Upon review, we find that a person of ordinary skill in the art would have had reason to modify Voorde in the manner FFP suggests. Voorde explicitly discloses the advantages of heating the medium, and there is no disagreement that heating to 50–52°C would have resulted in at least some reduced microbial load, which is all that the claims require.13 Indeed, Voorde describes that as a result of heating to 50–52°C, its medium is “(partially) sterilized.” Ex. 1003, 7. Kerry’s argument that Voorde does not disclose starting with a “sterile medium” (PO Resp. 25) is unavailing; as discussed above, we do not interpret anything in claim 1 or the ’304 patent 13 At oral argument, Kerry raised for the first time a claim construction argument that “heat treating,” as recited in the claims, requires heating to a level in excess of what is required in Voorde, and a person of ordinary skill would have understood the term to refer to sterilization.

“establishes that a POSITA would have been motivated to modify Brown in the manner proposed. Brown teaches that its battery casing with the stacking mechanism is used in both single and multi-cell batteries: A cell casing for a primary dry cell battery of the button type is disclosed which includes a case with a first elongated electrically conductive member affixed centrally to its exterior surface, and a cover with a second elongated electrically conductive hollow member affixed centrally to its interior surface in communication with an aperture. Both a single and a multi-cell battery are described which include the above battery casing. Ex. 1005, 1:11–18 (emphasis added). Consistent with this teaching, Brown’s Example I describes a cell casing “formed generally in accordance” with the casing depicted in Brown’s Figure that includes a stacking mechanism, in particular a screw (member 14) welded to the outside center of case 11. Id. at 2:58–81. In Example II, Brown teaches using the “cell casing of Example I,” which includes the stacking mechanism, in a singlecell battery. Id. at 3:1– 18. Brown explicitly states that the aperture in the cover is sealed when the cell is used in a single cell battery, but provides for no other modifications to the casing. Id. at 3:13–16 (“The aperture was then sealed by means of a short #2-56 round-head machine screw and a 10-mil thick polytetrafluoroethylene polymer gasket.”). In Example III, Brown similarly teaches a battery with fifteen stacked cell casings wherein, after each casing member of each cell was threaded into the hollow member of the cover of the adjacent, the aperture on the last cover was “sealed with a threaded screw as in Example II.” Id. at 3:19–29. These teachings demonstrate that Brown contemplated using the casing with the stacking mechanism in a single cell battery and accounted for that by sealing the aperture in the cover. In light of these disclosures in Brown, neither Petitioner nor Mr. Juzkow sufficiently explain why a POSITA would overlook Brown’s teaching that the casing includes the stacking mechanism regardless of the number of cells in the battery, in order to simplify the manufacturing process and produce a battery with a smooth cup surface that would reduce the space occupied by the battery when only a single cell is used. Pet. 19 (citing Ex. 1002 ¶ 57–59); see Ex. 1005, 1:11–18, 3:1–18. Mr. Juzkow’s testimony in this regard repeats the conclusory and unsupported assertions in the Petition, without citing to additional evidence or providing significant reasoning to support his statement. Mr. Juzkow’s testimony thus adds little to Petitioner’s conclusory assertions regarding a POSITA’s motivation to modify Brown, and is entitled to little weight. Xerox Corp. v. Bytemark, Inc., IPR2022- 00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). For these reasons, we are not persuaded that Petitioner makes a sufficient showing that a POSITA would have been motivated to modify Brown as proposed. Because Petitioner relies on its modified Brown with respect to Grounds 1A to 1E, we also conclude that that Petitioner does not, on this record, demonstrate a reasonable likelihood of prevailing in showing that any of claims 1–25 would have been obvious over the combined teachings of Brown, Higuchi, and Fujita.

“A reference is reasonably pertinent if, even though it may be in a different field from that of the inventor’s endeavor, it is one which, because of the matter with which it deals, logically would have commended itself to an inventor’s attention in considering his problem. In re Clay, 966 F.2d 656, 659 (Fed. Cir. 1992). In accord with Clay, a reference is reasonably pertinent if it logically would have commended itself to an inventor’s attention. The ’646 patent fairly describes the user of its sample container system as unskilled and it fairly describes the concerns to be addressed as the safe storage of a material in a receptacle in the cap when it describes the “home-base sample collection . . . allow[ing] for a much wider range of research options available” and existing sample collection devices having pierceable membranes as “a safety hazard to the sample donor as any wrong manipulation can lead to piercing the membrane and exposing the [potentially toxic] solution.” Ex. 1001, 2:53–58, 4:16–35. Moreover, the ’646 patent explicitly states that “there is a need for safer and easier to use sample collection devices.” Id. at 4:35–36. Similarly, Cho describes its device as “contain[ing] two kinds of materials in two separate spaces” that “communicate with each other as necessary” and the two materials mix together “using only a simple action.” Ex. 1004, 1:3–6, 1:25–27. Since sample collection containers and consumer beverage bottles are both containers for home-based use by the general public for combining an ingredient in a cap reservoir with the contents of the container, with similar concerns of ease of use, safety, and sealed reservoirs, one of skill in the art would have logically looked to other containers, such as the beverage bottle art, to solve problems related to ease of use, safety, and sealed reservoirs for sample collection containers. Compare Ex. 1004, 1:26–27 (describing the need to “mix two materials together . . . using only a simple action”), 1:29– 2:3 (describing the need to “maintain[] a good seal . . . so that the additive is not oxygenated or spoiled and the additive storage container can be easily applied”) with Ex. 1001, 4:1–8 (describing as an object that the “sample collection device may allow easy and safe collection of a donor specimen . . . with no risk of exposure of the donor to the toxic solution [and] allow the donor to safely mix the toxic solution and the specimen . . . with no risk of exposure of the donor to . . . the toxic solution nor any other hazard”), 4:29–31 (describing existing pierceable membrane devices that “can represent a safety hazard to the sample donor as any wrong manipulation can lead to piercing the membrane and exposing the solution”).” slip op. at 24

“Relying on Dr. Meinhart’s testimony, Petitioner argues that a person of ordinary skill in the art “would have had a bachelor’s degree in mechanical engineering, chemical engineering, biomedical engineering, molecular biology, (bio)chemistry, or an equivalent degree relevant to microfluidic biological cell analysis, and three to five years of experience with the construction of and application of microfluidic devices to cell culture and analysis.” Pet. 8–9 (citing Ex. 1002 ¶ 40). Patent Owner does not contest Petitioner’s proposed level of ordinary skill in the art. See PO Resp. 3–4 (citing Ex. 2012 ¶¶ 19–20).

In those proceedings, Patent Owner’s proposed construction for chamber is “an enclosed space within a microfluidic device,” and its proposed construction for retaining position is “a location in the chamber at which a cell is maintained during cell culture and media exchange.” Ex. 1013, 6, 8.

“selectively recovering a cell based on the response in the monitoring step. Although Dimov discloses non-selective recovery and briefly lists a few general techniques that might be used for either mixing or recovery, Dimov does not specifically indicate which of the techniques would be useful for recovery rather than just mixing, and Dimov does not explicitly disclose that any cell recovery would be selective. Nor has Petitioner shown that Dimov inherently discloses selectively recovering any particular cell that has been cultured and monitored, because, as Dr. Gale persuasively testifies, Dimov’s removal techniques could, as far as a person of ordinary skill in the art would have known based on Dimov’s disclosure, be merely for “removing . . . unwanted particles out of the capture chamber/trench.” Ex. 2012 ¶ 64; see also id. ¶ 63 (“Dimov . . . may suggest removing cellular materials (rather than intact cells) after capture . . . .”). In other words, given Dimov’s general focus on performing experiments within the trenches and the lack of any specific disclosure about how or why to remove cells, Petitioner has not met its burden to show that Dimov’s potential cell-removal techniques would have necessarily been based on a response of a specific cell being cultured and monitored in limitation 1D. We also agree with Patent Owner that Dimov does not disclose any specifics about how to carry out a selective cell removal based on one of Dimov’s listed techniques, such as laser tweezers. See PO Resp. 8–9. Nor does Petitioner meet its burden of showing that such a technique would have been within the ordinary skill in the art at the time of the claimed invention. “In order to anticipate, a prior art disclosure must also be enabling, such that one of ordinary skill in the art could practice the invention without undue experimentation.” Novo Nordisk Pharms., Inc. v. Bio-Tech. Gen. Corp., 424 F.3d 1347, 1355 (Fed. Cir. 2005) (citing SmithKline Beecham Corp. v. Apotex Corp., 403 F.3d 1331, 1342 (Fed. Cir. 2005)). Given the labyrinthine outlet channels leading from Dimov’s chambers to the common waste stream and Dimov’s lack of any disclosure of a way to identify and extract cells in the outlet streams, we credit Dr. Gale’s testimony that there would have been substantial obstacles to recovering any specific cells that had been liberated from a trench in Dimov’s device. See Ex. 2012 ¶ 63. Petitioner has not shown that a person of ordinary skill in the art would have overcome those obstacles without undue experimentation.” slip op. at 23

Nevertheless, as we discuss below, we find these arguments unpersuasive.
