“When rehearing a decision on petition, the Board will review the decision for an abuse of discretion. See 37 C.F.R. § 42.71(c). An abuse of discretion may be determined if a decision is based on an erroneous interpretation of law, if a factual finding is not supported by substantial evidence, or if the decision represents an unreasonable judgment in weighing relevant factors. See Arnold P’ship v. Dudas, 362 F.3d 1338, 1340 (Fed. Cir. 2004). The party challenging the decision has the burden of showing the decision should be modified, and the request for rehearing “must specifically identify all matters the party believes the Board misapprehended or overlooked, and the place where each matter was previously addressed” in its papers. 37 C.F.R. § 42.71(d).” slip op. at 2

“Owner’s interpretation of “carrier” as meaning “one or more components for supporting ROSA components such as an AWG.” Dec. 9 (quoting Pet. 11). For our analysis of Petitioner’s challenges, we referred to this interpretation of “carrier” as Petitioner’s second alternative construction. Id. We also noted that Petitioner appeared to dispute Patent Owner’s interpretation when it argued that “carrier” should mean “a ceramic or silicon substrate.” Id. (quoting Pet. 10). We referred to this interpretation of “carrier” as the first alternative construction. Id. Rather than resolve this apparent dispute about the meaning of “carrier,” we found that both of Petitioner’s anticipation challenges failed under both interpretations of “carrier.” Id. at 10–26. Because we found that Petitioner had failed to carry its burden regardless of which interpretation of “carrier” applied, we found it unnecessary to resolve the dispute over that interpretation. Id. at 9–10. For the reasons expressed in Parts II.B–C below, we maintain our conclusion that Petitioner has failed to demonstrate a reasonable likelihood of proving that either Shen or Soldano anticipates any claim under either interpretation of “carrier.” Accordingly, Petitioner fails to demonstrate an abuse of discretion in our alleged “refusal” to interpret “carrier.”” slip op. at 3

“We determine that Petitioner cannot credibly certify that the ’418 patent is available for inter partes review, based on a claim of priority on the face of the ’418 patent to the ’939 provisional application filed prior to the effective date of the AIA, where, as here, Petitioner contradictorily contends in the Petition that the ’939 provisional application “does not support all claim limitations” of the ’418 patent.4 Id. If Petitioner’s allegation that claims of the ’418 patent are not supported by the ’939 provisional application is correct, then the ’418 patent would be a post- AIA patent for which a petition may not be filed earlier than 9 months after the ’418 patent issued. See 35 U.S.C. § 311(c). Thus, based on the arguments and evidence presented by Petitioner, Petitioner fails to show that the ’418 patent is eligible for inter partes review when Petitioner filed the Petition less than two months after the ’418 patent issued. 35 U.S.C. § 311(c), 37 C.F.R. § 42.102(a)(1).

“We agree with Patent Owner that the Petition fails to demonstrate that Kahn discloses element [1.2] because the evidence cited does not disclose a “first computer system being configured to provide remote control of the first pump or first valve” (i.e., a fluid-handling device). Kahn is directed to providing access to fluid sensing data and analyzing and providing visual information on that data, but Petitioner has not identified any disclosure of the capability to remotely control fluid-handling devices. See, e.g., Ex. 1005, code (54), 1:27–36, 2:50–3:2. More specifically, Kahn’s disclosures that Petitioner relies on for allegedly teaching remote control are deficient. We discuss each.

“target value” is part of a command that is sent from a computing device to a server and then to a controller. The controller then receives a measurement of the fluid by a sensor and determines whether the measurement satisfies the “target value.” If the measurement does not satisfy the “target value,” further operations are undertaken. The recited operation sequence makes clear that the plain and ordinary meaning of “target value” is not as Dr. Wooley opines because the particular operating condition that a device is in at a particular time is represented by the measurement taken by the sensor, 11 Some claim language less relevant to construing “target value” was omitted for ease of reference. which the controller then uses to determine whether the measurement satisfies the “target value.” Additionally, claim 1 recites that the “target value” is sent as part of a command to the controller. The “target value” is not sent to the controller from the sensor, as might be expected if the plain and ordinary meaning of “target value” were as Dr. Wooley opines. Petitioner and Dr. Wooley’s construction would also result in “target value” meaning effectively the same thing as the measurement of the fluid by the sensor, a concept that is separately recited in claim 1 and to which the “target value” is compared. The Specification of the ’680 patent does not support Petitioner’s understanding of the plain and ordinary meaning of “target value.” Although the Specification does not recite “target value,” it recites “target state,” and describes “target state” sufficiently to understand the plain and ordinary meaning of “target” as used in “target value” and “target state.” In particular, the ’680 patent explains that “[i]n some embodiments, the process 104 includes receiving, via a network interface, from a remote user device, (e.g., via a command-center server) a command to change a state of a fluid-handling device to a target state.” Ex. 1001, 11:48–51. This portion reflects that the command is seeking to change a state of a fluid-handling device to a target state. In other words, the “target value” or “target state” is not generally “the particular operating condition that a device is in at a particular time”; rather, it is a value or state that the fluid-handling device is desired to be in, as Patent Owner and Dr. Durham explain. Additionally, just as claim 1 recites a directional component for the “target value” to be sent to the controller in a command, so too does the Specification describe a “target state” as being sent in a command from a remote user device. Thus, the Specification clearly supports the plain and ordinary meaning proposed by Patent Owner and Dr. Durham and not the plain and ordinary meaning proposed by Petitioner and Dr. Wooley. slip op. at 14

Specifically, the teachings from Almadi identified by Petitioner refer to process data, which is data retrieved from the remote subsystems/field devices. Thus, we understand that Almadi’s teaching—of using an Ethernet switch to transmit “process data”—describes transmitting data from the remote subsystems/field devices. See Ex. 1005, 3:13–17, cited in Pet. 15. But claim 1 and particularly element [1.4], recites “sending, with the server, the target value to the network address [which identifies a controller of the fluid-handling device13] via the network,” which is different than sending process data from the field devices to the remote host or database server for storage.” slip op. at 19

Tyco Healthcare Grp., LP, 616 F.3d 1249, 1254 (Fed. Cir. 2010) (quoting Gaus v. Conair Corp., 363 F.3d 1284, 1288 (Fed. Cir. 2004)) (alteration in original). Thus, the claim language suggests that the “integral knit tongue” is a component distinct, at least to some degree, from the “upper.” See also Ex. 1001, 2:27–28 (the Specification stating that “[a] knitted component including the upper and an integral knit tongue is incorporated into the article of footwear.”). Limitation 1d reinforces this understanding by requiring the tongue to be joined to a portion of the throat area of the upper. See id. at 6:35–38 (the Specification indicating that the “throat area” is an area of the upper); cf. Ex. 2014, 18–19 (defining “Throat”: “The main opening of a shoe extending from the vamp [(the front part of a shoe upper that covers the toes and part of the foot)] to the ankle.”). In addition to suggesting that the tongue is a component distinct from the upper, the claim language indicates that the integral knit tongue extends through a throat area. See Ex. 1001, 25:10–11 (limitation 1b: “an integral knit tongue . . . extending through a throat area of the knitted component”). With that context, we turn to the parties’ arguments.” slip op. at 11

“claim language does not specify it, both parties contend that the “portion of the knitted component” constitutes the majority of the upper. See Pet. 25– 26, 30 (Petitioner applying in this ground that which it characterizes as Patent Owner’s claim construction position); Prelim. Resp. 43 (Patent Owner noting that the Specification states that “a majority of upper 120 is formed from a knitted component 130,” and contending that limitation 1a1 means that “a majority of the upper must be knitted.” (quoting Ex. 1001, 6:57–59)). Nevertheless, we determine for the following reasons that Petitioner has not shown sufficiently that central textile element 60 of Dua-956 defines an upper within the meaning of the claims. See Pet. 26. Petitioner contends that, “[w]ith respect to what defines the upper, the ’636 patent discloses that the ‘upper generally extends over the instep and toe areas of the foot, along the medial and lateral sides of the foot, under the foot, and around the heel area of the foot.’” Pet. 27 (citing Ex. 1001, 1:44–46, 6:66–67). Petitioner reasons that, “[a]s such, the ’636 patent describes the upper as extending around six parts of the foot: (1) the instep area, (2) the toe area, (3) the medial side, (4) the lateral side, (5) under the foot, and (6) the heel area.” Id. Applying this reasoning to the reference, Petitioner contends that, “[o]f the six upper parts identified in the ’636 patent, only two of them—the medial and lateral sides—are not formed by the central textile element 60,” and therefor “the majority of the parts of the upper are formed by the central element 60.” Id. at 30 (citing Ex. 1002 ¶¶ 103–109). Petitioner provides an annotated versions of Figures 8B and 8C of Dua-956, reproduced below, to depict its contentions. Id. at 30. Above are Figures 8B and 8C of Dua-956—which are, respectively, perspective views depicting a second step and a third step in assembling the article of footwear (Ex. 1029, 3:41–45)—with central textile element 60 shaded green. As Petitioner concedes (Pet. 30) and as the annotated figures above show, central textile element 60 does not form the medial and lateral sides of the footwear. Thus, even if central textile element 60 constitutes the majority of parts of the upper, the sides of the upper remain undefined by the central textile element. Petitioner does not explain adequately how the upper is defined when the side components are missing. We determine that Petitioner has not demonstrated adequately for institution that Dua-956 discloses “a portion of the knitted component defining the upper,” as recited in independent claim 1.” slip op. at 20

“Petitioner contends that “both upper 70 and 30' are constructed as a single, unitary knit element that defines the upper, and it would have been obvious to construct upper 30 in the same manner.” Pet. 65. Petitioner next turns to Horii, asserting that “Horii discloses “shoes 1 that are characterized by the fact that the entire upper is constructed of a single piece of upper member 2 that is made through weft knitting or circular knitting.’” Id. at 67 (citing Ex. 1017, 9) (emphasis omitted). Petitioner reasons that “[a] POSITA would have been motivated to manufacture Dua-956’s upper 30, for example, using the multilayer, single fabric of Horii because Horii’s single-piece knit upper would have provided upper 30 with a seamless structure.” Id. at 68. We disagree with Petitioner’s assertion that “[c]onstructing Dua-956’s upper 30 as a single, unitary knit component would not materially change the analysis under Ground 1A.” Pet. 70. In Ground 1A, Petitioner contends that “‘forward portion 61’ of the central textile element 60 is an integral knit tongue that extends through a throat area of the knitted component in the assembled upper 30.” Id. at 34. During the assembly of footwear 10, forward portion 61 is flipped over the top of the footwear and the separate textile elements 40 and 50 (the sides of the footwear) are stitched to the lateral and medial edges (64a and 64b) of forward portion 61—the purported tongue. See Ex. 1029, 9:5–11, Figs. 8B, 8C. Petitioner does not explain adequately how, when modifying the embodiment used in Ground 1A to have a seamless top portion, the purported integral knit tongue is retained in that combination. See Pet. 70 (Petitioner asserting that the proposed combination would still have an exterior surface, an inner surface, lace elements 33, channels 44/54, and loops 35, “along with the other structures identified under Ground 1A,” but not specifically discussing the purported integral knit tongue.). We determine that Petitioner has not demonstrated a reasonable likelihood of demonstrating that claims 1–6, 8–17, and 19–27 would have been obvious over Dua-596 alone or in combination with Horii.” slip op. at 24

- Skill levelSkill level petitioner adoptedDecided for petitioner
“Petitioner contends that: A person of ordinary skill in the art (“POSITA”) in the field of the ’562 patent in February 2012 would have been someone with at least a few years of experience in knit materials and knitting methods and machines that can be used in making footwear, or a bachelor’s degree in textile-related sciences, engineering, or industrial product design, or equivalent academic or work experience, including in the footwear industry. EX1002, ¶68. Such a person of ordinary skill would have at least a general understanding of general construction processes and materials used in the manufacturing process of fabric-based articles. For individuals with a lower educational level, a person could still be of ordinary skill in the art provided that person’s working experience compensates for any such lower educational level, or vice versa. See id. Pet. 22. Patent Owner states that, “[f]or the purposes of this Preliminary Response only, Nike applies Petitioner’s proposed level of skill in the art.” Prelim. Resp. 15. Petitioner’s definition is consistent with the level of ordinary skill reflected in the prior art references of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (recognizing that the prior art itself may reflect an appropriate level of skill in the art). For purposes of this decision, we apply Petitioner’s definition of the person of ordinary skill in the art.” slip op. at 8

“inquiries.” Medichem, S.A. v. Rolabo, S.L., 353 F.3d 928, 933 (Fed. Cir. 2003). “The first step in both analyses is a proper construction of the claims . . . [and t]he second step in the analyses requires a comparison of the properly construed claim to the prior art.” Id. Although an explicit claim construction analysis by a petitioner is not required in every case, a petition nonetheless must identify how the challenged claims are to be construed and how, as so construed, they are unpatentable under the statutory grounds asserted. 37 C.F.R. § 42.104(b)(3)–(4). And, being part of a prima facia case, such an analysis is part of Petitioner’s burden to demonstrate a reasonable likelihood of prevailing on its patentability challenges. Petitioner has failed to satisfy the threshold burden for every ground based on this construction.” slip op. at 14

“We do not find Petitioner’s contentions regarding the two annotated figures to be persuasive. First, those contentions, and the cited opinions of Dr. Adanur, are based on a claim construction that, as discussed above, we reject and for which neither party advocates. Second, Petitioner does not explain adequately why a person of ordinary skill in the art would discern, even with Petitioner’s added red ovals, a tongue distinct from the upper and tongue extending through the throat area. We also do not find persuasive Petitioner’s contentions regarding differing textures. See Pet. 32–33. Even if differing textures could rise to the level of distinguishing an integral knit tongue from the upper, the purported tongue texture 48" is not confined to the area identified by Petitioner as the tongue. See Pet. 31 (annotated Figure 11, reproduced above). For example, texture 48" outside of Petitioner’s oval appears to wrap approximately halfway around the ankle opening, which is not argued to be consistent with an ordinary artisan’s understanding of a tongue. Or, put another way, there is no indication that the portion of the 48" texture within Petitioner’s red oval, which purportedly represents the tongue, is distinguishable from the remaining portion of the 48" texture outside of the red oval. We are not persuaded that Petitioner has demonstrated a reasonable likelihood of proving that a person of ordinary skill in the art would consider the relatively large area depicted as having texture 48" to be an “integral knit tongue.” In light of the above, we determine that Petitioner has not demonstrated a reasonable likelihood of prevailing on its challenge to independent claim 1 and its dependent claims 2–4 as anticipated by Dua-592.” slip op. at 23

“1. Reason to reduce contaminant levels We agree with Patent Owner that Petitioner identifies no teaching in the prior art providing any reason to reduce levels of 6,7-dimethoxy-quinoline-4-ol specifically. And while Brown does teach a desire to form “substantially pure” compounds, Brown focuses on “at least about 90 wt.%” of the compound, then lists specifically “about 90, about 91, about 92, about 93, about 94, about 95, about 96, about 97, about 98, about 99 and about 100% wt. %.” Ex. 1003 ¶ 97.

“to modify Brown’s process with Kubo to eliminate the added step. See, e.g., Id. ¶ 73. But even with that combination, Dr. Dichtel states only that a “POSA would have expected there to be a decrease in the amount of 6,7- dimethoxy-quinoline-4-ol at the end of cabozantinib (L)-malate’s synthesis that was attributable to hydrolytic degradation of the 4- (nitrophenoxy)quinoline intermediate by avoiding its use in the synthesis.” Id. ¶ 78. That is not, however, the standard for inherency. It must be the necessary result, not a possible expected result. The Federal Circuit in Par explained that: Inherency, however, may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient. If, however, the disclosure is sufficient to show that the natural result flowing from the operation as taught would result in the performance of the questioned function, it seems to be well settled that the disclosure should be regarded as sufficient.” slip op. at 28

“However, neither Petitioner nor Dr. Jansky provide specific data on the record before us showing the actual measured homozygosity of either of the inbred lines, US-W 5309 and US-W 5315. And Phumichai experimentally demonstrates that Dr. Jansky’s assumption that theoretical heterozygosity reduction of 50% per generation is not necessarily accurate, stating the “observed average percentage of reduction of heterozygosity per generation (38.4% or 38.5%) was lower than the theoretically expected value of 50%.” Ex. 1005, 982. Indeed, Phumichai disclosed that the “SOPH [Section-based observed percentage of heterozygosity] decreased steadily from the original 100% in 99H2–1 (S0) to the family means of 62.4% in 3H2 (S1), 37.9% in 3H3 (S2).” Id. at 981. That is, Phumichai experimentally shows that in an S2 generation of a potato line, the heterozygosity was 37.9%, resulting in homozygosity of about 62.1%, below the 75% theoretically expected and the 75% required by claim 1 of the ’841 patent. Therefore, the evidence of record does not show that the S2 generation of potato lines in Jong necessarily satisfies the homozygosity recitation in claim 1 of the ’841 patent, and so cannot establish on the record before us that Jong inherently teaches this limitation.” slip op. at 15
