“The ’750 patent states that “the fluid pathway can be a radially serpentine fluid pathway which causes the fluids received in the off axis chamber to flow back and forth around a radius of the off axis chamber,” also using “radially serpentine fluid pathway” to refer to this rotation around the chamber radius “while also traversing a length of the off axis chamber.” Ex. 1001, 4:34–41 (emphasis added). This is the only description of “radially” serpentine flow in the ’750 patent. Notably, the ’750 patent does not use “radially” or “serpentine” to describe a fluid pathway “which causes the fluids to spiral around the central chamber within the off axis chamber along a length of the off axis chamber,” instead referring to such a fluid pathway as a “helical fluid pathway.” Id. at 4:41–44. See CAE Screenplates, Inc. v. Heinrich Fiedler GmbH & Co. KG, 224 F.3d 1308, 1317 (Fed. Cir. 2000) (“In the absence of any evidence to the contrary, we must presume that the use of . . . different terms in the claims connotes different meanings.”); Bd. of Regents of the Univ. of Tex. Sys. v. BENQ Am. Corp., 533 F.3d 1362, 1371 (Fed. Cir. 2008) (“Different claim terms are presumed to have different meanings.”). Inst. Dec. 11–12. We explained that the flow path depicted above, which is equivalent to that of Figure 14 of the ’750 patent, “flows circumferentially about the central chamber.” Id. at 14. We maintain this interpretation. Stated differently, the depicted flow is around a longitudinal axis of the chamber. See MTA PG 6 (describing the flow path depicted above as “a back and forth flow path around a longitudinal axis of the off axis chamber; that is, a circumferentially serpentine pathway”); see also Ex. 2003 ¶ 40 (Dr. Neitzel describing the flow path depicted above as “a back and forth flow path around a longitudinal axis of the off axis chamber”). The flow is not around a radius of the chamber, which Patent Owner recognizes is required for a flow path to be radially serpentine. See PO Resp. 10 (“Patent Owner agrees with the Board’s conclusion in the [Institution Decision] that ‘radially serpentine’ as recited in the claims of the ’750 patent means a back and forth flow around a radius of the off axis chamber.” (citation modified)); PO Sur-reply 2 (agreeing that “radially serpentine” requires “a back and forth flow around a radius of the off axis chamber”).” slip op. at 14

“We agree with Patent Owner that neither Petitioner nor its witness, Mr. Nixon, has explained adequately how Thurler’s disclosure of its tube e being perforated for two thirds of its length “contemplates other lengths of perforations.” See Pet. 48; Ex. 1013 ¶ 212. Such conclusory assertions fail to apprise us of why an ordinarily skilled artisan would have been motivated to modify Thurler’s device in contradiction to Thurler’s explicit disclosure. We are also not persuaded by Petitioner’s proffered reasoning for modifying Thurler’s device. First, the modification is not a matter of design choice because the perforations allow the gases generated by firing the projectile to pass into the space between tubes e and g where they partially expand. See Ex. 1015, 1:84–91. Thus, modifying the number of perforations necessarily affects the flow of gases through the device. Next, neither Petitioner nor Mr. Nixon explains adequately how reducing the amount of perforation in tube e results in an increased fluid length. See Pet. 49; Ex. 1013 ¶ 213. Rather, although less fluid may enter into tube e with Petitioner’s modification, it appears that that fluid would travel the same distance along tubes e and h as in Thurler’s unmodified device. Finally, neither Petitioner nor Mr. Nixon explains adequately how limiting the amount of gases generated by firing the projectile from entering the expansion zones of tubes g and h provides any benefit. To the contrary, limiting the amount of gases in the manner suggested by Petitioner would reduce the suppression of such gases, resulting in a less effective device. Moreover, Thurler discloses that “there is still a space of a few millimeters between [tubes] e and g which is necessary” to prevent the application of “pressure on the projectile causing the same to deviate.” Ex. 1015, 1:106–2:3. Thus, Petitioner’s modification would not result in the passage of gases occurring only at the first three of Thurler’s tubular sleeves as asserted by Petitioner. Additionally, in the Institution Decision, we explained that Petitioner did not provide adequate reasoning to support the proposed modification of Thurler’s device regarding parent claim 1 to have concentric tubes around the central tube e. See Inst. Dec. 29–31. This shortcoming, which we maintain, carries through to dependent claim 6. Accordingly, for the foregoing reasons, Petitioner has not shown, by a” slip op. at 26

“We agree with Petitioner that the amendment is broadening. Petitioner’s witness testified that he “wouldn’t call a BB gun a high energy device or a high energy weapon.” Paper 33, 18:4–6. Thus, per Petitioner’s witness, use of a BB gun would not be covered by claim 22, no matter what is discharged from the BB gun. However, if high energy material is discharged from that same BB gun, that use would be covered by proposed substitute claim 43 (assuming the other claim recitations were met). See id. at 21:10–12 (Dr. Neitzel agreeing that “if something produces a high energy material, it automatically is a high energy weapon”). Thus, by deleting “high energy device” and replacing that language with “weapon,” proposed substitute claim 43 impermissibly broadens the scope of claim 22. See Sisvel Int'l S.A. v. Sierra Wireless, Inc., 81 F.4th 1231, 1241 (Fed. Cir. 2023) (“But if a substitute claim ‘is broader in any respect it is considered to be broader than the original claim even though it may be narrower in other respects.’” (citation modified) (quoting Hockerson-Halberstadt, Inc. v. Converse Inc., 183 F.3d 1369, 1374 (Fed.

We are persuaded by Patent Owner’s contention (PO Resp. 12) that the applicant, by including the term “current” in the claims, intentionally narrowed the claims to power consumption reductions that occur temporally in the present, rather than those that occur in the future. See Pet. Reply 6–7 (Petitioner asserting that Patent Owner’s position is “inconsistent with the specification’s examples,” but then arguing that the Specification does not support that position rather than pointing to any purported inconsistencies).

“Given the interchangeable nature taught for various features of Wang’s embodiments, it would have been a routine and obvious matter for a POSA to combine aspects from Wang’s various embodiments (e.g., data acquisition, internal hardware, data analysis performed by the UMC receiver 400 and/or the display 200). Moreover, many of Wang’s embodiments–particularly of specific smart appliance types– include common components, thus further confirming combinability of aspects of the disclosed embodiments. A POSA would have had a reasonable expectation of success in combining features of the embodiments together. Id. at 77–78 (citing Ex. 1003 ¶¶ 201–203). We determine that these reasons are inadequate and too generic to satisfy Petitioner’s burden as they lack a clear explanation of what and how “aspects from Wang’s various embodiments” are proposed to be combined along with reasoning specific to that proposal. Petitioner, for example, does not explain adequately or persuasively why a person of ordinary skill in the art would have added a display that purportedly receives and analyzes data to a “smart appliance,” when that appliance already has an application processor that purportedly receives and analyzes the same data.

“We understand Petitioner’s phrase “experience working on software and/or hardware used to manage charging processes for electric vehicles” to encompass data processing systems similar to that proposed by Patent Owner, but with a slightly narrower area of application. We determine that Petitioner’s definition, as set out in the block quote above, 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 the purposes of this decision, we apply Petitioner’s definition, as block quoted above, of the person of ordinary skill in the art. We note, however, that were we to adopt Patent Owner’s assessment, the outcome of this Decision would be the same. Cf. Pet. Reply 15 (Petitioner asserting that “[Patent Owner] takes issue with the level of ordinary skill in the art . . ., but never argues that the level impacts how the Board should understand the arguments. Petitioner’s positions apply regardless.”).” slip op. at 9

“We are not persuaded that the Specification evidences a clear intent by the patentees to redefine (either explicitly or by implication) or to otherwise narrow the scope of the claim terms “request” and “response,” as Patent Owner urges. The statements in the Specification upon which Patent Owner relies are referring to “Request 414” and “Response 418.” See PO Resp. 27 (quoting Ex. 1001, 12:3–4, 12:12–14). As indicated by the reference numbers, the Specification is discussing a specific request and a specific response in the context of Figure 4, which is described as depicting “an illustrative embodiment.” See Ex. 1001, 10:51–53 (“FIG. 4 is a system for managing a charging process of an electric vehicle in accordance with an illustrative embodiment.”), 12:1–19, Fig. 4. By stressing the illustrative nature of the embodiment of Figure 4, the patentees indicated an intent for it to not be limiting. See also Ex. 1001, 15:44–47 (the Specification stating: “The description of the present invention has been presented for purposes of illustration and description, but is not intended to be exhaustive or limited to the invention in the form disclosed.”); Hill-Rom Servs., Inc., 755 F.3d at 1373 (“[T]hose terms [including, datalink 39] are used synonymously only in describing a particular numbered component in the figure depicting the preferred embodiment, and never in describing the datalink of the invention generally.”). At oral argument, Patent Owner’s counsel, relying on the opinion of Dr. Cameron, argued that a person of ordinary skill in the art would “read the definition without the reference numbers.” Tr. 43:23–44:9. Thus, we understand Patent Owner to argue that the Specification provides an explicit definition when one reads out a portion of the Specification—converting, for example, “Request 414 is a message” to “Request is a message.” This is not persuasive as it involves editing the evidence to conform to Patent Owner’s argument, rather than an argument supported by the Specification as written by the patentees. Patent Owner does not direct us to any portion of the Specification that clearly defines “request” and “response” generally or, for example, uses phrasing implying that those terms are defined for “the present invention.” See, e.g., Hill-Rom Services, Inc., 755 F.3d at 1372 (“For example, we have held that disclaimer applies when the patentee makes statements such as “the present invention requires . . .’ or ‘the present invention is . . .’ or ‘all embodiments of the present invention are . . . .’”); Astrazeneca, 384 F.3d at 1339 (discussing defining by implication and determining that the “specification’s statement that ‘[t]he solubilizers suitable according to the invention are defined below’ provides a strong signal of lexicography.”).” slip op. at 17
- Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageDisclaimer not foundDecided for petitioner
“We fail to discern a clear disparagement of the use of signals in the Specification that would justify excluding signals from the scope of the claimed invention. The Specification does not mention in these excerpts the use of signals, and thus does not characterize “using signals as less ‘complete, flexible, and interoperable,’” as Patent Owner impliedly argues. PO Sur-reply 11. The Specification characterizes “the most rudimentary charging scenarios” as including situations such as a car owner merely plugging the electric vehicle into a common electric outlet at the owner’s house, and suggests that illustrative embodiments are an improvement in that they apply to “much broader and more complex sets of circumstances than this simple scenario.” See Ex. 1001, 6:60–7:2. An example of a “complex transaction[]” is the car owner using a charging station located away from the owner’s house and being required to pay for the charge. See id. at 7:2– 11. To the extent there is any disparagement, it is merely of the simple scenario of the owner plugging the car into the standard household outlet. Cf. Epistar Corp. v. Int’l Trade Comm’n, 566 F.3d 1321, 1336 (Fed. Cir. 2009) ([T]his court also recognizes that disparaging comments alone do not necessarily show a manifest or express disavowal of the criticized subject matter.”). Additionally, Patent Owner does not direct us to any portion of the Specification that indicates, for example, that the use of messages is a very important feature of the claimed invention and that alternatives (e.g., signals) are disparaged. See Hill-Rom Servs., Inc., 755 F.3d at 1372 (citing Inpro II Licensing, S.A.R.L., 450 F.3d at 1354–55); see id. at 1377 (holding that there is no disavowal or lexicography where “[t]here is no language that extolls the virtues of interfaces that both send and receive messages or language that disparages interfaces that only send messages.”).” slip op. at 20

“Sur-reply 15 (citing Ex. 1021, 161:5–21). Patent Owner overstates that testimony, which is that “[t]here’s actually disincentive for using messages all together.” Ex. 1021, 161:17–18. Regardless, even if correct, the existence of some disincentives does not necessarily negate a motivation to make the proposed combination. Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006) (“[A] given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine.”). We find that Petitioner’s assertion—that a person of ordinary skill in the art would be motivated by a desire to assure a safe and commercially-desirable system (Pet. 53)—to have rational underpinning. See In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006). Patent Owner argues that Dr. Cameron “explained [that] . . . it would not be simple because Hotta uses two-stage charging subroutines.” PO Sur-reply 16 (citing Ex. 2005 ¶ 118). We disagree with Patent Owner’s characterization of Dr. Cameron’s testimony. The cited paragraph 118 states that Hotta’s figures depict “two-stage charging subroutines different from both the ’391 patent and Kimura,” and that there are “fundamental differences.” Ex. 2005 ¶ 118. Dr. Cameron does not go so far as to opine that combining the teachings as Petitioner’s proposes would not be considered simple by a person of ordinary skill in the art. See id.; see also Leapfrog Enters., Inc. v. Fisher-Price, Inc., 485 F.3d 1157, 1162 (Fed. Cir. 2007) (“Leapfrog presents no evidence that the inclusion of a reader in this type of device was uniquely challenging or difficult for one of ordinary skill in the art.”). Dr. MacCarley, on the other hand, credibly testifies that “making use of Hotta’s command keys in Kimura’s system . . . would have been a simple substitution of one known element (Kimura’s lightly- described main switch) for another known element (Hotta’s command keys) to achieve predictable results (a charging process that can be stopped by pressing Hotta’s charging stop command key . . .).” Ex. 1009 ¶ 147. We credit Dr. MacCarley’s testimony over that of Dr. Cameron’s because it is consistent with a sufficiently reasoned rationale of a simple substitution and is supported by the references.” slip op. at 48
