      “Petitioner misstates the Decision’s reasoning. As is clear from the previous discussion, we determined that Petitioner’s articulated reasons for combining EP’536 with CN’180 lacked a rational underpinning, not because “EP’536 does not relate to ‘air bags,’” but because the means by which EP’536’s device inflates differs fundamentally from that of CN’180’s device. Dec. 17–18. Petitioner did not acknowledge this critical difference in the Petition, and continues not to do so in its Rehearing Request.” slip op. at 5

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundNot shown unpatentable

      “EP’536 with CN’180 lacked a rational underpinning because EP’536’s inflation mechanism differs fundamentally from CN’180’s inflation mechanism. Dec. 17–18. As we stated, whereas CN’180’s fall-protection belt uses an airbag that requires an external source of pressurized air to inflate, EP’536’s garment does not need an external inflation device because “the gas generating agent 18 in each envelope automatically generates gas and inflates the envelopes in response to rising temperatures.” Id. at 18 (citing Ex. 1004 ¶ 15; Ex. 1005 ¶¶ 5, 19). This difference reflects the fundamentally different purposes of the two devices: CN’180’s device is designed to provide “fall protection” to, e.g., “elderly people,” (Ex. 1005 ¶ 1, 3), whereas EP’536’s device provides “adaptive thermal insulation” for, e.g., garments worn by fire fighters. Ex. 1004 ¶¶ 1–3, 250. Because of the different means by which EP’536’s and CN’180’s devices inflate and the different purposes for doing so, we were not persuaded that one of ordinary skill in the art would have combined the references as Petitioner proposed. Dec. 18. We further noted that the modification would not have improved the reusability of EP’536’s device “by having only one mechanism to recharge,” because EP’536’s “gas generating agent does not need any ‘mechanism to recharge.’” Dec. 18. Instead, we noted EP’536’s teaching that its gas generating agent “automatically recombines or condenses in response to a temperature decrease to return the envelopes, and therefore the garment, to its original thickness, at which point the gas generating agent is ready for subsequent reactivation.” Id. (citing Ex. 1004 ¶¶ 139–141). Finally, we determined that replacing EP’536’s envelopes with CN’180’s airbag “would have made EP’536’s invention unsuitable for its intended purpose: providing a protective garment with ‘adaptive thermal insulation.’” Dec. 19. We stated that “Petitioner does not suggest, and we have found nothing in the record to establish, that CN’180’s airbag would provide this feature.” Id. at 20.” slip op. at 3

    • Obviousness (§103) › KSR rationalesMotivation not foundNot shown unpatentable

      “rationales for combining EP’536 and CN’180. Reh’g Req. 6–7. First, Petitioner asserts that we “improperly rejected Petitioner’s ‘simple substitution’ evidence in view of [the Board’s] incorrect conclusion that EP’536 does not disclose an ‘external source of inflation [EP’536’s dosing aids].’” Id. at 6 (citing Dec. 18–19). This argument is unpersuasive at least because, as we discussed above, EP’536’s dosing aids do not constitute an external source of inflation. Petitioner further argues that we incorrectly evaluated its “obvious to try” rationale because, contrary to our analysis, Petitioner did in fact identify a problem to be solved by its “finite number of solutions”: “simplify[ing] the design and reduc[ing] the number of required inflation mechanisms.” Id. at 6–7. The Petition’s entire “obvious to try” discussion is as follows: [A] POSITA would have found it obvious to try a one-piece airbag 10 with strip-shaped inflation units 12 in the EP’536- CN’180 airbag system because it would have been a selection from a finite number of identified predictable solutions (i.e., using one chamber with connected individual inflation units 12 versus multiple individual envelopes 20). 5 Petitioner also argues that dosing aids are “needed in order to make the disclosed device reusable.” Reh’g Req. 5–6. This is incorrect, as EP’536 conveys that the reusability of the device is a result of the gas generating agent condensing or recombining when temperatures fall. Ex. 1004 ¶¶ 139– 141. Even if it were true, however, it is unclear how it would support Petitioner’s argument. Pet. 16. As is evident, Petitioner did not identify a design need, market pressure, or other problem that would have been addressed by its identified “solutions,” and therefore we were not persuaded by this rationale. Dec. 19. Petitioner’s attempt to cure this deficiency in its Rehearing Request is tardy. We cannot misapprehend or overlook an assertion that Petitioner fails to make in the Petition. It is also insufficient. Petitioner does not provide any evidence of a known design need or market pressure to “simplify [EP’536’s] design” or reduce the number of “required inflation mechanism” it uses.” slip op. at 7

      “For purposes of our analysis, we need only address the meaning of “planar structure,” and only to note that this limitation requires that all portions of the casing body, when inflated against the first mesh portion, second mesh portion, and tie elements, “form a planar structure” when the casing body is inflated. This is evident from both the claim language and the written description of the ’065 patent. Limitation [1e] of claim 1 recites that in the inflated condition, “said portions of the casing body” are “inflated against said first mesh portion, said second mesh portion, and said tie elements.” We understand “said portions of the casing body” to refer to all of the portions of the casing body. Likewise, “said first mesh portion, said second mesh portion, and said tie elements” refers to the entire mesh structure recited in limitation [1a]. Thus, this limitation requires all of the casing-body portions to inflate against the entire mesh structure to form the “planar structure.” This reading is consistent with the Specification. The Specification teaches that “[t]he first mesh portion and the second mesh portion together with the tie elements determine with the casing body the final shape of the inflatable element,” which “can reach a generally flat and planar final shape.” Ex. 1001, 4:19–23; see also id. at 4:59–5:3 (teaching that the casing body inflated within the mesh structure results in a “globally planar structure”).

      “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

Based on these disclosures, we agree with Patent Owner that Petitioner has not established that Almadi discloses element [1.4]. 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

There are no disclosures, however, in the above passages that there is remote control of fluid handling devices, that there is a user command on a control interface that actuates an actuator, or that there is a command sent to the facility actuators via a network connection, as required in limitations [18.5]–[18.7] and [18.9]–[18.12], respectively.

      “The failure to use the word “means” in a claim element creates a rebuttable presumption that § 112 ¶ 6 does not apply. Williamson v. Citrix Online, 792 F.3d 1339, 1348 (Fed. Cir. 2015) (en banc). The presumption can be overcome and § 112 ¶ 6 will apply if the challenger demonstrates that the claim term fails to “recite[ ] sufficiently definite structure” or else recites “function without reciting sufficient structure for performing that function. “Construing a means-plus-function claim term is a two-step process.” Id. at 1351. “The [tribunal] must first identify the claimed function.” Id. “Then, the [tribunal] must determine what structure, if any, disclosed in the specification corresponds to the claimed function.” Id.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

      “We are persuaded by Patent Owner that the term “automatically” in “to automatically disengage the first and second catch structures” means that it is not just the force applied by the user that disengages the first and second catch structures, but also the bias of the mouthpiece that helps to disengage the first and second catch structures. In the first instance, we agree with Patent Owner that the claim itself recites that, upon actuation, the mouthpiece assembly is “release[d]” to “move via its bias from the stowed configuration to the dispensing configuration.” See Ex. 1001, 21:59–64. This meaning is supported by the Specification which states: “In some examples, the mouthpiece assembly is biased toward the dispensing configuration and thus moves automatically under its bias upon release by the user-release mechanism.” Ex. 1001, 1:64–67. We further agree with Patent Owner that the plain and ordinary meaning of “automatic” is that the user operation alone is not responsible for the action. For example, in one dictionary cited by Petitioner, “automatic” is defined as “2: having a self-acting or self-regulating mechanism.” See Ex. 2007, 1.11 The district court construction is consistent therewith. The district court identified two functions, the first of which is the same as that of the ’028 patent, i.e., “Automatically disengaging the first and second catch structures upon actuation of the user release mechanism and thereby releasing the mouthpiece assembly to move via its bias from the stowed configuration to the dispensing configuration.” See Section II.C.1, supra. In discussing that function, the district court states: “While a user may impart force upon user engagement portion 260 to release the mouthpiece, the bias of the mouthpiece towards the dispensing configuration causes the mouthpiece to move automatically, satisfying the requirements of Claim 1.” Ex. 2002, 16.

      “First, Petitioner’s reason to modify Kiyota “to provide the advantage of a bite actuated mouthpiece” (Pet. 42) does not explain why one would use Choi’s mount 100. Petitioner has not clearly established that to use a bite-actuated mouthpiece requires mount 100. Choi describes that “cap assembly 14 may include a mount 100 to which the bite-actuated mouthpiece is removably mounted, or secured.” Ex. 1005 ¶ 46. This description suggests that mount 100 is not a required component for a bite-actuated mouthpiece. Our understanding is supported by Patent Owner’s expert, who testified that using Choi’s mount as a “rigid collar member” in Kiyota’s mouthpiece assembly does not require combining its bite-actuated valve because “the bite-actuated portion has nothing to do with the alleged rigid collar member portion.” Ex. 2001 ¶ 119 (citing Ex. 1005 ¶ 46); see also Prelim. Resp. 55. Thus, Petitioner has not adequately supported this first reason to modify Kiyota to use Choi’s mount 100.” slip op. at 22

    • Claim Construction › Functional claiming / §112(f) means-plus-function › Whether §112(f) applies (Williamson, nonce words)§112(f) appliesDecided for petitioner

      “as a means-plus-function limitation under 35 U.S.C. § 112, sixth paragraph, because “mechanism” is a nonce word for performing the claimed function without reciting structure for performing that function, and a POSITA would not have understood the term to have “a sufficiently definite meaning as the name for a structure that performs the claimed function.” Pet. 16–17 (citing Ex. 1003 ¶ 39). For claim 1, Petitioner identifies two distinct structures described in the ’028 patent that correspond to the claimed “user release mechanism” for performing the claimed functions. Id. at 34. Specifically, Petitioner asserts that the ’028 patent describes a first embodiment in which the corresponding structure includes sliding member 238, and its component parts. Id. at 34– 35 (citing Ex. 1001, 12:50–13:25, 13:29–33). In the second embodiment, the corresponding structure includes user engagement portion 260 on rigid collar 170. Id. at 35–36 (citing Ex. 1001, 13:40–54). Petitioner does not separately address the structure corresponding to the “user release mechanism” as recited in claim 21. Id. at 53‒54 (relying on the same arguments presented for unpatentability of claim 1). court issued a claim construction order in the parallel litigation construing the term “user release mechanism” as a means-plus-function limitation under § 112, sixth paragraph. Prelim. Resp. 23 (citing Ex. 2002, 12–15). The district court ruled that the corresponding structure for claim 1 includes “[s]liding member 238, including its component parts,” or “[u]ser engagement portion 260.” Ex. 2002, 15. For claim 21, the district court ruled that the corresponding structure includes “[s]liding member 238, including its component parts” or “[u]ser engagement pad 240, planar portion 242, tabs 244, collar engagement portion 254, depression 256.” Id. at 17. Patent Owner indicates that, “[f]or purposes of this proceeding only,” it does not dispute that the claimed user release mechanisms are means-plusfunction limitations, and it does not dispute the corresponding structure identified by Petitioner, even though the district court did not specifically identify engagement portion 260 as corresponding structure for claim 21. Prelim. Resp. 25 (citing Ex. 2002, 15–19). Although Patent Owner does not dispute Petitioner’s proposed interpretation of the “user release mechanism,” because claim interpretation is a matter of law and the dispositive issue in this Decision turns on the interpretation of this claim limitation, we address it in this Decision. We agree with the parties that the “user release mechanism” elements recited in claims 1 and 21 are means-plus-function limitations governed by § 112, sixth paragraph. See 35 U.S.C. § 112 ¶ 6 (“An element in a claim for a combination may be expressed as a means or step for performing a specified function without the recital of structure, material, or acts in support thereof, and such claim shall be construed to cover the corresponding structure, material, or acts described in the specification and equivalents thereof.”). “means,” it uses the nonce word “mechanism” without reciting structure for performing the functions recited in the claims. See Williamson v. CitrixOnline, LLC, 792 F.3d 1339, 1350 (Fed. Cir. 2015) (“Generic terms such as ‘mechanism,’ ‘element,’ ‘device,’ and other nonce words that reflect nothing more than verbal constructs may be used in a claim in a manner that is tantamount to using the word “means” because they ‘typically do not connote sufficiently definite structure’ and therefore may invoke § 112, para. 6.”).” slip op. at 13

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

      “[U]nder § 112, ¶ 6 equivalence, functional identity is required” and “[s]tructural equivalence under § 112, ¶ 6 is met only if the differences are insubstantial, that is, if the assertedly equivalent structure performs the claimed function in substantially the same way to achieve substantially the same result as the corresponding structure described in the specification.” (citing Chiuminatta Concrete Concepts, Inc. v. Cardinal Indus., Inc., 145 F.3d 1303, 1308 (Fed. Cir. 1998)). Here, Petitioner states that Kiyota’s lock release buttons 40 “perform the claimed function in the same way to achieve the same result” as the ’028 patent’s sliding member 238, and its component parts (Pet. 37) without providing sufficient supporting explanation or evidence. Petitioner explains only that the two structures operate in “substantially the same way” by a user pressing an element that that slides towards the mouthpiece assembly to disengage the catch structures. Id. at 37–38 (citing Ex. 1003 ¶ 89). The Petition does not discuss any of the differences between Kiyota’s structure and the ’028 patent’s structure or provide an explanation of why these differences are insubstantial. Indeed, as Patent Owner persuasively explains, there are notable differences in the “way” the two structures perform the claimed function and the “result” they achieve. See Prelim. Resp. 39–40 (discussing the ’028 patent’s one-finger operation and indirect catch disengagement, versus Kiyota’s two-finger operation and direct catch disengagement). Moreover, the analysis in Dr. Vallee’s declaration substantially parallels the discussion in the Petition and does not provide any additional explanation or evidence to show that the differences between the “way” the two structures operate or the “result” they achieve are insubstantial. Compare Ex. 1003 ¶¶ 85–91, with Pet. 34–38. For these reasons, Petitioner fails to show sufficiently that Kiyota discloses an equivalent structure to the structure described in the ’028 patent corresponding to the “user release mechanism” recited in claim 1. Accordingly, Petitioner has not met its burden to show a reasonable likelihood that claim 1 is unpatentable as obvious over Kiyota. slip op. at 23

      “These deficiencies in analysis raise the question of whether the Petition adequately identifies the number of actual challenges, and evidence supporting each, with the degree of particularity required of petitions in our forum.

See generally Pet. An inter partes review based on 24 distinct grounds raised against a single claim, supported by analysis lacking in particularity, potentially burdens Patent Owner unduly and makes inefficient use of the Board’s resources.
