    “In the Response, Patent Owner states that it “does not dispute” the definition of one of ordinary skill in the art proposed by Petitioner, but Patent Owner “reserves the right to address [the definition] should new issues materialize.” PO Resp. 6. Patent Owner did not address this issue in the Sur-reply. As noted in the Decision on Institution, Petitioner’s proposed definition appears generally consistent with the record, including the prior art. See Dec. Inst. 8 (citing In re GPAC Inc., 57 F.3d at 1579). We remove the phrase “at least” in both listed options, however, as that phrase adds ambiguity. Further, Patent Owner has not argued at trial that Petitioner’s proposal for the level of ordinary skill leads to an improper understanding of how a skilled artisan would have understood either the challenged patent or the prior art. In the analysis below, we continue to apply the level of ordinary skill in the art adopted in the Decision on Institution, as proposed by Petitioner.” slip op. at 9

    “Network LLC, 929 F.3d 1350, 1357 (Fed. Cir. 2019). At first glance, the language of the limitation at issue—which, again, recites “the compressed air and the operative fluid mix together in said mixing chamber to form the fluid dispersion”—would seem to require the “fluid dispersion” (under the stipulated construction) to be fully formed in the “mixing chamber.” In other words, the language of the limitation alone would seem to support Patent Owner’s proposed construction for the “form the fluid dispersion” limitation. But the claim construction analysis does not end with consideration of the claim language alone. Next, we turn to the Specification. The Federal Circuit has said that the specification “is the single best guide to the meaning of a disputed term.” Phillips, 415 F.3d at 1315 (quoting Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996)). Here, the discussion in the Specification of precisely the same language as in the limitation at issue strongly supports that “to form a fluid dispersion” in the limitation at issue requires only initial mixing of the compressed air and operative fluid in the mixing chamber, with further “formation” of the ”fluid dispersion” occurring downstream of the mixing chamber: More importantly, the “predetermined amount” of compressed air and the “preselected amount” of the operable fluid are initially mixed together in the mixing chamber 226 to form a fluid dispersion. The diffusion chamber 112" is further structured to facilitate the formation of a plurality of substantially uniform droplets, as defined hereinabove, in the fluid dispersion prior to discharge from the diffusion chamber 112" through discharge port 132. Ex. 1001, 10:62–11:2 (emphasis added) (discussing Figure 6), quoted, in part, at Pet. Reply 6–710; see also Ex. 1001, 5:64–6:4 (same language, except without double primes, in a discussion of Figures 1 and 2). To be sure, certain passages in the Specification could be read to indicate that a “fluid dispersion” must be fully formed in the “mixing chamber.” See, e.g., Ex. 1001, 6:11–12 (“More in particular, the suppression chamber 232 receives the fluid dispersion from the mixing chamber 226.”); see also id. at 7:22–33, 11:39–52 (both implying that a “fluid dispersion” is formed in the mixing chamber). But the passage block quoted directly above (and the similar one bridging columns 5 and 6) more directly addresses the issue at hand—i.e., the scope of “form the fluid dispersion”—by using the same” slip op. at 13

    “To satisfy its burden of proving obviousness, a petitioner cannot employ mere conclusory statements. The petitioner must instead articulate specific reasoning, based on evidence of record, to support the legal conclusion of obviousness.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1380 (Fed. Cir. 2016); TriVascular, Inc. v. Samuels, 812 F.3d 1056, 1066 (Fed. Cir. 2016) (“Although the KSR test is flexible, the Board ‘must still be careful not to allow hindsight reconstruction of references . . . without any explanation as to how or why the references would be combined to produce the claimed invention.’”) (citation omitted). Based on the complete record, we agree with Patent Owner that “Petitioner’s asserted motivation boils down to the conclusory statement that given Goubet and Kaiser, ‘it was well known in the field at the time of the invention that droplets of greater uniformity result in uniform droplet evaporation.’” PO Resp. 31 (quoting Pet. 59). We agree with Patent Owner that Petitioner’s discussion of the alleged reasons to combine (Pet. 59) is insufficient to support the proposed combination here. See Magnum Oil, 829 F.3d at 1380. Specifically, we are not persuaded that Kaiser’s teachings—which relate to combustion (Ex. 1014 at 43)—would have led one of ordinary skill in the art to the proposed modifications, which would allegedly “improve the smoothness (i.e., less harsh) of the aroma generated as the oil droplets evaporate in the surrounding airspace.” See Pet. 59 (emphasis added); White Pet. Decl. ¶ 251 (same); see PO Resp. 32 (“Rather, Dr. White merely describes the ability to achieve the effect as in the claimed patent, not why a [person of ordinary skill in the art] would look to the field of electrospray injection and combustion in mesoscale power-generation systems, using high-voltage electric fields to generate charged fuel droplets for controlled combustion in catalytic micro-combustors when considering atomization for scents.”). For these reasons, we determine, in light of the complete record, that Petitioner has not shown by a preponderance of the evidence that one of ordinary skill in the art at the time of the invention would have had reason to combine Goubet and Kaiser, as proposed. slip op. at 32

Charge Fusion responds that Tesla improperly narrows the meaning of this claim limitation. PO Resp. 15 (arguing this claim term “is not just limited to ‘changing or otherwise fluctuating cost (or price)’ as alleged by the Petition” (emphasis added)). Although we consider Tesla’s proposed construction to identify an exemplary “dynamic attribute of an electric charge provider,” we see no need to limit the meaning of this limitation as proposed by Tesla. Indeed, Tesla agrees. See Pet. Reply. 7 (arguing only that this claim limitation “at least includes” such an example). And Charge Fusion does not contend otherwise. See PO Resp 15 (arguing only that this limitation “is not just limited to” cost fluctuations). As such, we see no need to further construe this claim limitation. 2. “determine . . . a charging schedule for the vehicle” Limitation 1[g] recites “determine, based at least on the one or more charging preferences and at least one current value of a dynamic attribute of an electric charge provider, a charging schedule for the vehicle.” Independent claim 8, 15, and 22 recite a materially identical limitation.

    “Initially, we note that, as claimed, there is no express restriction on the manner in which the “amount” or “charge” is specified or otherwise expressed. Indeed, the Specification uses both “desired charge percent level” and “desired charge range level” as alternative ways for a user to specify an “amount of charge.” Ex. 1001, 14:53–15:8 (emphases added). The Specification defines “desired charge range level” as meaning “a desired distance to travel.” Id. at 15:3–8. Elsewhere, the Specification describes that a user may specify the amount of charge as follows: “the user may indicate a desired charging level (and/or a desired charging level may be automatically calculated) based on a desired distance of travel.” Id. at 19:49–57 (emphasis added). More specifically, annotated Figure 7 of the ’987 patent, reproduced below, demonstrates how a user may select “amount of charge” in terms of a desired mileage range 720 or a percentage level 718. See Pet. Reply 2. As shown in red, annotated Figure 7 illustrates that a user selects “desired charge level 720” on “vehicle charge indicator 714” by moving a slider to a value specified in “miles” (e.g., 110 miles). The Specification, after discussing selecting a desired charge percent level 718, explains: The user may also or alternatively view and/or change the desired charge range level 720. An estimate of how far the vehicle can travel on a given charge amount (which may be a general average and/or may be computed based on a specific itinerary and/or past driving habits) can be determined, for example, and utilized to express the desired charge level in terms of distance capable of being traveled. In such a manner, for example, a user may determine a desired distance to travel (e.g., how far it is from home to work or vice versa) and may set the desired charge range level 720 to match the desired distance. Ex. 1001, 14:65–15:8. Thus, the Specification confirms that “amount of charge” may be expressed in terms of a desired mileage as well as a desired percentage level.” slip op. at 11

    “We disagree. Charge Fusion’s reliance on Wonderland is misplaced and does not support the proposition for which it is cited. In Wonderland, the district court denied the accused infringer’s motion for summary judgment of invalidity, in part, because genuine issues of material fact existed as to whether there was sufficient motivation to combine the prior art. Wonderland, 988 F. Supp. 2d at 511. As such, the district court’s Wonderland decision does not constitute a final ruling on the motivation to combine issue, and the Federal Circuit’s summary affirmance of the district court’s ruling neither addresses the issue nor reflects how the issue was resolved at trial. See Wonderland NurseryGoods Co. v. Thorley Indus., LLC, 644 F. App’x 1011 (Fed. Cir. 2016). Moreover, contrary to Charge Fusion’s assertion, Tesla correctly notes that although Ferro refers to wireless charging, it provides no implementation details. Ex. 1004 ¶ 36; Ex. 2006, 54:8–55:9. Nonetheless, Ferro does describe manual options for initiating charging, and Tesla’s expert credibly testifies that one of ordinary skill in the art would have been motivated to apply Oyobe’s vehicle sensor to allow a user to initiate Ferro’s charging methods more easily without having to leave the vehicle. See Ex. 1003 ¶¶ 146, 151, 152 (citing Ex. 1004 ¶ 109).

    “full charge” for the battery, and thus, Tesla fails to explain how the combination of Sutardja with Donnelly’s battery bar graph image “would allow a user to select a specific amount of charge or how this would result in a unitary vehicle charge indicator,” as claimed. PO Resp. 30. According to Charge Fusion, “[l]imiting the single option of ‘full charge’ as described in Sutardja would defeat the purpose of implementing a slider” as taught by Donnelly. Id. (citing Ex. 2008 ¶ 72). We disagree. Charge Fusion’s argument rests on the mistaken premise that Sutardja only contemplates selecting a full amount of charge for the battery and not an amount below a full charge, i.e., a partial charge. But that is not what Sutardja says. More accurately, Sutardja teaches that the user specifies the amount of charge—"The user interface module 108 may comprise a key pad, a display, a microphone, and/or a speaker (all not shown). A user of the vehicle 102-1 may use the user interface module 108 to set charging parameters for charging the battery 14.” Ex. 1011 ¶ 243. Elsewhere, Sutardja teaches that the user may set a “predetermined level” of charge— The charge monitoring module 150 may inform the control module 112 when the battery 14 is charged to a predetermined level (e.g., full charge) that may be indicated in the charging parameters. Subsequently, the charge monitoring module 150 may stop charging the battery 14 by deactivating the converter 156 and the charging module 152. The power meter 24 may measure the amount of power received from the utility company 23 during the charging operation. Id. ¶ 270 (emphases added). Although that passage indicates that a “full charge” is an example of a “predetermined level” of charge, nowhere does it exclude the selection of a lesser amount. Indeed, the passage contemplates the ability to “stop charging the battery,” which indicates that selection of the predetermined level may be less than a full charge. Id. Thus, we are not persuaded by Charge Fusion’s argument to the contrary. Rather, in our view, Tesla demonstrates by a preponderance of the evidence that the Sutardja-Donnelly combination teaches a “unitary vehicle charge indicator” that includes at least “first” and “second” portions and that one of ordinary skill in the art would have had reason to successfully combine their respective teachings in a manner that allows a user to predetermine, i.e., specify, an amount of charge. slip op. at 17

This is especially applicable here, where neither Dr. D’Ambrosio’s nor Dr. Schwartz’s declaration was prepared for this proceeding, and neither declarant was subject to cross examination on their opinions. Moreover, neither of the declarants was opining on claim construction; rather, they were addressing indefiniteness and/or written description issues. See Ex. 1058 at 7 (heading addressing definiteness); Ex. 2026 at 18 (heading addressing written description). Further, Dr. Schwartz appears to have been making an argument about certain patent claims (not the challenged ’333 patent) based on Patent Owner’s own statements made during prosecution of a separate patent application. See Ex. 2026 ¶ 47 (“[T]he similar term used in the ’284 patent claims (‘data of severity of sleep disorder symptoms’) does not find written description support in the specification by a disclosure of the same statistics disclosed in Wright, because CleveMed argued those statistics are not related to severity of sleep disorder symptoms.” (emphasis added)). Patent Owner has not persuaded us that Dr. Schwartz’s testimony has direct applicability to the claim term at issue here. Dr. Borkholder’s testimony is likewise unpersuasive. Aside from citing Dr. D’Ambrosio’s and Dr. Schwartz’s declarations, Dr. Borkholder cites Exhibits 2027 and 2016. These exhibits discuss indices such as AHI and RDI that are used to assess the severity of a patient’s symptoms, but Patent Owner has not adequately explained how they bear on construction of the claim term at issue here, which is not addressed in these exhibits. Ex. 2022 ¶¶ 32–33. Accordingly, we accord Dr. Borkholder’s claim construction opinions little weight, because they are unsupported by reference to objective, corroborating evidence of record. See, e.g., Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985) (“Lack of factual support for expert opinion going to factual determinations . . . may render the testimony of little probative value in a validity determination.”); Xerox Corp. v. Bytemark, IPR2022-00624, Paper 9, 15 (PTAB 2023) (precedential) (explaining that declaration testimony that “is conclusory and unsupported” and which “adds little to the conclusory assertion for which it is offered to support . . . is entitled to little weight”).” slip op. at 23

    “We find that Petitioner has the better argument. Tidal volume refers to “the volume of air that is inspired or expired during a respiratory cycle.” Ex. 2028, 13–14; PO Resp. 10. “[H]ypopnea events are defined as a reduction of ≥50 % or 74 % in tidal volume from baseline and apnea events as absence of tidal volume for at least 10s.” Ex. 2028, 13–14 (emphasis omitted). Toge teaches that a control unit analyzes collected data (e.g., the flow rate) and calculates tidal volume. Ex. 1044 (Toge) ¶¶ 34–38. The calculated tidal volume is “a quantified level of severity data based on the subject’s sleep apnea symptoms during the therapy” because it represents, e.g., the “level of airway obstruction the patient experiences during the sleep apnea treatment using the PAP device.” Pet. 15. As Dr. Chatterjee explains: Toge discloses that tidal volume Fp is a quantified level of data because Toge discloses that Fp is monitored with respect to threshold values (id., [0051]) and because Fp is a function of Ft, Fa, and Fb, which are quantitative values. Toge discloses that tidal volume Fp is severity data because Toge discloses that tidal volume is indicative of whether the patient’s breathing warrants “emergency measures” (id., [0039]) and whether to “send an alert” in “an emergency where the patient’s breathing has drastically weakened” (id., [0055]). . . . . Because Toge discloses determining tidal volume (determine a quantified level of severity data) based on Ft, Fa, and Fb (id., [0035]), which corresponds to the subject’s condition (subject’s sleep apnea symptoms) while using the device (during the therapy) (id., [0036], [0037]), Toge discloses determin[ing] a quantified level of severity data based on the subject’s sleep apnea symptoms during the therapy. Ex. 1005 (Chatterjee Decl.) ¶¶ 122–125. Patent Owner’s attempt to dismiss tidal volume as a mere “breathing metric” is unavailing. First, Petitioner correctly “notes that in the paragraph PO cites to in Dr. Schwartz’s declaration, he indicates that breathing metrics are a level of severity data.” Pet. Reply 8 (citing Ex. 2026 ¶ 46 (“standard sleep disordered breathing metrics” [ ] were well validated indicators of the type and severity of sleep disordered breathing”)). Second, Dr. Kirkness explains that tidal volume represents the level of airway obstruction, e.g., apnea “is the most severe form of reduction in airflow [and] the absence of airflow results in quantified tidal volume of zero milliliters per breath.” Ex. 1003 (Kirkness Decl.) ¶¶ 157, 159; see also PO Resp. 10–11 (Patent Owner recognizing that an apnea is defined as absence of tidal volume for at least 10 seconds). The calculated tidal volume thus indicates severity because it is used to adjust the PAP system, e.g., in the case of decreasing tidal volume, a medical professional can change the airflow settings “to counter/treat the more severe level of airway obstruction observed from the decreasing tidal volume.” Ex. 1003 (Kirkness Decl.) ¶ 158; Pet. 15–16; Ex. 1044 (Toge) ¶ 39.” slip op. at 26

    “Trove contends that a person of ordinary skill in the art “would have had an undergraduate degree in mechanical engineering or equivalent coursework, and a year or more of experience in designing, prototyping, and/or manufacturing fluid containers or similar products” and that “[m]ore work experience may substitute for a lower level of education, and vice versa.” Pet. 15 (citing Ex. 1002 ¶ 25). While CamelBak offers “a similar, though slightly different level,” it nonetheless “discerns no material difference between the definitions provided by the parties for purposes of the Board’s decision in this proceeding.” PO Resp. 27.

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

    “We will not bite. CamelBak’s original assertion—that the plain and ordinary meaning of the constituent parts of “mouth” and “piece” is “a piece (or part) that goes in the mouth”—underscores the fallacy of CamelBak’s additional physical contact requirement. PO Resp. 28 (emphasis added). Indeed, in support of that earlier assertion, CamelBak pointed to the very dictionary definition that we relied on at institution in construing “mouthpiece” as a part that either “goes in the mouth or to which the mouth is applied.” See id. at 31 (citing Ex. 2005 (emphasis added)). Even the original testimony of CamelBak’s own expert confirms that one skilled in the art “would understand that the term ‘mouthpiece’ is commonly known in the art as a part designed for a user’s mouth,” without any requirement for physical contact with the mouth. Ex. 2016 ¶ 58 (citing Ex. 2005) (emphasis added)). And nothing in the Specification limits that common understanding. Although, indisputably, the Specification contemplates an embodiment where the user physically contacts the mouthpiece with their teeth (i.e., a bite-actuated mouthpiece), it also contemplates an embodiment where the user simply inserts the bottle in their mouth and commences fluid flow by squeezing it. See Ex. 1001, 10:9–13. That disclosure supports a meaning of “mouthpiece” that simply requires placement in the opening of the user’s mouth without necessarily incurring physical contact with some portion of the mouth, such as the teeth, tongue, or lips. Indeed, had CamelBak wished to premise the meaning of “mouthpiece” on some sort of physical contact with the mouth, it knew how to do so. For instance, the independent claims of CamelBak’s earlier ’255 patent, which is the subject of the related 1137 IPR, are limited in just such a manner, as they recite “wherein the resilient mouthpiece is adapted to resiliently compress responsive to compressive forces applied to the resilient mouthpiece by a user’s teeth.” Ex. 2023, at 20–25 (emphasis added). Thus, we reject CamelBak’s attempt to narrow our construction of “mouthpiece” to something other than “a part (as of an instrument) that goes in the mouth or to which the mouth is applied.” Neither the intrinsic nor extrinsic evidence supports the narrower construction proposed by CamelBak.” slip op. at 11

    “In reply, Trove argues that CamelBak’s “novel” construction that the mouthpiece moves with rotational motion about that same axis of rotation defined by the two joint as the pivotal mount and in the same direction as the pivotal mount “are inconsistent with the claim language’s plain and ordinary meaning and find no support in the intrinsic and extrinsic record.” See Pet. Reply 16. But, because we find that, when properly construed, the claimed “pivotal movement with the pivotal mount” about “two joints that define a pivotal axis” requires that the mouthpiece rotate about the same axis and in the same direction as the pivotal mount, we reject Trove’s argument as unavailing. And, although we agree with Trove that Nakajima’s mouthpiece engages in counter-clockwise rotation about a “Second Pivot Axis” when Nakajima’s lid 4 is opened (id. at 20–22), that rotation is about a different axis—one defined by Nakajima’s protrusions 24 rather than the claimed “pivotal axis” defined by Nakajima’s hinge shafts 19—and in a different manner—an upward and counterclockwise path rather than the claimed “pivotal movement with the pivotal mount” defined by Nakajima’s lid 4. Finally, in an alternative theory, Trove and its expert use “image- manipulation tools” in an attempt to show that Nakajima’s mouthpiece engages in some initial “clockwise-rotation” with Nakajima’s lid as it is opened. See Pet. Reply 18–24. We reject that theory as entirely conjectural and unsupported by the evidence.” slip op. at 39

    “We disagree. As discussed above, the proper construction of “for pivotal movement with the pivotal mount” requires that the mouthpiece mirror the rotational movement of the pivotal mount, i.e., rotate about the same axis as the pivotal mount and in the same direction as the pivotal mount. See supra § II.B.3. But Nakajima’s mouthpiece does neither, and, thus, does not exhibit the claimed “pivotal movement with the pivotal mount” about “two joints that define a pivotal axis for . . . the pivotal mount axis,” as properly construed.” slip op. at 36

    “Initially, we note that “amount of charge” reflects no express limitation on the manner of expressing the “amount” or the “charge.” And the Specification uses both “desired charge percent level” and “desired charge range level” as alternative ways for a user may specify an “amount of 3 As recited in independent claims 10, 19, and 28 charge.” For example, the Specification describes that a user may specify an amount of charge by specifying a desired travel distance as follows: “the user may indicate a desired charging level (and/or a desired charging level may be automatically calculated) based on a desired distance of travel.” Ex. 1001, 19:49–57 (emphasis added). Therefore, “amount of charge” may also refer to a desired mileage or range.

    “We disagree with Patent Owner. First, Patent Owner’s reliance on Wonderland as announcing a rule having broad effect is misplaced. Patent Owner contends that the “Federal Circuit has confirmed that where the primary reference already includes the function of the secondary reference, an allegation to incorporate that function into the primary reference is improper hindsight and no motivation to combine exists.” Id. at 29 (citing Wonderland NurseryGoods Co. v. Thorley Indus., LLC, 988 F.Supp. 2d 479, 498–99 (W.D. Pa. 2013), aff'd, 644 F. App'x 1011 (Fed. Cir. 2016); citing Kinetic Concepts, Inc. v. Smith & Nephew, Inc., 688 F.3d 1342, 1368 (Fed.Cir.2012))). Patent Owner’s citation to Wonderland does not support the proposition for which it is cited, namely that the Federal Circuit has “confirmed” that incorporating a function from a secondary reference into a primary reference is “improper hindsight” that precludes a motivation to combine teachings from the primary and secondary references. In Wonderland, the district court denied an accused infringer’s motion for summary judgment of invalidity, in part, due to its finding that genuine issues of material fact existed for the issue of whether sufficient motivation to combine prior art existed. Wonderland, 988 F. Supp. 2d at 511. The Wonderland decision does not constitute a final ruling on that issue, and the Federal Circuit’s summary affirmance of the final ruling by the district court does not address the issue or reflect how the issue was resolved at trial. Wonderland NurseryGoods Co. v. Thorley Indus., LLC, 644 F. App’x 1011 (Fed. Cir. 2016). Second, Petitioner also correctly points out that although Ferro refers to wireless charging, it provides no implementation details. Ex. 1004 ¶ 36; Ex. 2003, 54:8–55:9. Ferro also describes manual options for initiating charging, Ex. 1003¶ 146 (citing Ex. 1004 ¶ 109), and that an ordinarily skilled artisan would have been motivated to apply Oyobe’s vehicle sensor to allow a user to initiate Ferro’s charging methods more easily without the user having to leave the vehicle, Ex. 1003 ¶¶ 151, 152. Accordingly, we find that Petitioner has established that an ordinarily skilled artisan would have been motivated to incorporate Oyobe’s use of a sensor to establish presence of a vehicle near a charging station into Ferro’s system.” slip op. at 20

Patent Owner’s argument fails to account for the level of skill and creativity of an ordinarily skilled artisan, who would have possessed a bachelor’s degree in engineering and could have easily accounted for the differences in scale depicted by Letendre’s and Donnelly’s controls.

We noted in the Institution Decision that “construing the claim term ‘surround’ to mean ‘enclose’ does not further inform or clarify to a person of ordinary skill in the art what is encompassed by the claim limitation.” Dec. 15. We reach the same conclusion here on the full record and find no basis to rewrite the Challenged Claims to replace “surround” with “enclose.” To the extent Patent Owner can be understood to suggest that we import additional limitations into the claims based on the exemplary figures in the ’209 patent, we decline to do so. Regardless, given the recognition by the Parties that “surround” and “enclose” are synonymous, our determinations in this Decision would have been the same had we adopted Patent Owner’s proposed definition of “surround” to mean “enclose.” Further, with regard to the claim language “configured and dimensioned to surround at least a portion of the teeth of the patient,” Patent Owner proposes construing “a portion of the teeth” as “at least some teeth.” Resp. 9 (citing Ex. 2007 ¶ 44). Patent Owner, however, offers no sufficient explanation in its Response to explain how why a “portion of the teeth” means “at least some teeth.” The Specification does not provide an explicit definition of “a portion of the teeth” and does not suggest an intention to use a meaning of the term “a portion of the teeth” that is particular to the ’209 patent. To the extent Patent Owner can be understood to imply that we should import additional limitations into the Challenged Claims based on the exemplary figures in the ’209 patent, we decline to do so.

    “We disagree that Dr. Durham does not possess the necessary level of skill in the art to qualify as an expert in this case. Looking at the specification of the ’689 patent and the prior art of record, we think Masaba sets the bar too high. We acknowledge that one of ordinary skill in the art should have some education and/or experience in the mechanical art of conveying aggregate materials, but we do not think opining on the ’689 patent and asserted prior art necessarily requires that person to have the amount of education and experience that Masaba advocates. The ’689 patent relates generally to an “aggregate transferring system for receiving aggregate from a vehicle and elevating the aggregate to a higher vertical level for deposit into, for example, a silo.” Ex. 1001, 1:15– 18. And, as described in the ’689 patent and discussed later, the transferring system is an assembly of known types of conveyors, such as a belly-dump truck conveyor, a bucket elevator, and an articulated belt conveyor, for transferring the aggregate horizontally and vertically from a belly-dump truck to the discharge point, such as a silo. Without doubt, Dr. Durham has enough education and experience to reliably opine on the combination of known parts.” slip op. at 8

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Plain and ordinary meaningNo construction needed

    “We reject this argument for several reasons. First, nowhere does the plain language of the claims specify how the aggregate is conveyed or moved from the conveyor extension assembly’s inlet to its outlet, be it passively by means of gravity or actively by means of a conveyor belt. Instead, the claims simply use those verbs according to their plain and ordinary meaning, which is “to transfer or deliver” or “to cause to go or pass” from one place to another. See Ex. 3001, 253 (defining “convey”), 760 (defining “move”).10 Second, the specification of the ’689 patent similarly uses these terms in a plain and ordinary sense, without ever attributing to them some sort of special meaning. See, e.g., Ex. 1001, 4:9–12 (“The apparatus 10 is suitable for performing the transfer of aggregate from 10 We reference the original pagination of the dictionary in which these definitions appear. one location to another, such as, for example, from a vehicle carrying the aggregate to a silo 1 for storing the aggregate.”). The ’689 patent specification also makes clear that active conveyance of the aggregate is an option and not a requirement of the claimed invention, stating that the conveyor extension assembly “may further include a conveyor belt 150.” Ex. 1001, 10:60–66 (emphasis added). Limiting claim elements 1[h] and 1[i] to a device “for actively conveying” or “for actively moving aggregate” would improperly import limitations from the specification into the claims. Thus, based on the intrinsic evidence, we determine that claim elements 1h and 1k are properly construed to encompass passive and/or active movement of the aggregate via the conveyor extension assembly.” slip op. at 20

    “Petitioner has the better position, as we agree with Petitioner that the ’034 patent discloses an embodiment that uses transparent potting as a window, rather than to form the overall form factor and encapsulate components: [Figure] 16C is a perspective view of the WCD with potting material 1630. As described above, the PCB, battery, and components can be disposed within the space. Once disposed therein, a potting 1630 can be provided atop the components and within the cutaway portion 1616. The potting 1630 can be transparent to allow for transmission of light through the cutaway portions 1616. Ex. 1001, 20:51–57. This configuration is shown below in Figure 16C. “[Figure] 16C is a perspective view of the WCD with potting material.” Ex. 1001, 6:1–2. As Figure 16C shows, potting material 1616 forms a window in only a portion of the WCD’s exterior. can be used to encapsulate components and form the overall form factor in some embodiments. E.g., Ex. 1001, 17:4–8, 18:61–62. But Patent Owner does not persuade us that claim 12 is limited to those embodiments. PO Resp. 29; SuperGuide Corp. v. DirecTV Enters., Inc., 358 F.3d 870, 875 (Fed. Cir. 2004) (“Though understanding the claim language may be aided by the explanations contained in the written description, it is important not to import into a claim limitations that are not part of the claim.”). Accordingly, we do not construe claim 12’s “external transparent potting” as requiring material that “forms the ‘overall form factor of the WCD 120, in addition to providing a housing for one or more electronic components,’” as suggested by Patent Owner. PO Resp. 29. Nor do we construe the claim language as requiring material that “also fills the space and encapsulates the components,” as suggested by Patent Owner. Id.” slip op. at 11

    “We are not persuaded by Petitioner’s arguments and find that Patent Owner has the better position. Although Schröder describes some aspects that are similar to those of a printed circuit board, Petitioner has not sufficiently demonstrated that a person having ordinary skill in the art would understand Schröder’s inlay 12 or carrier foil to be a “printed circuit board,” as recited in independent claims 1, 11, and 16. As an initial matter, while Schröder refers to a “circuit board” in another context, it never refers to the carrier foil or inlay in its finger-ring embodiment as such. See Ex. 1007, 22:48–49; see also Ex. 1079 ¶ 21 (Dr. Anthony acknowledging that Schröder’s only reference to a “circuit board” is “unrelated to Schröder’s finger-ring teachings”). Instead, Schröder describes features of that inlay, explaining that “[t]he carrier foil itself consists of a flexible plastic material, e.g.[,] PET or Kapton” and “antenna coil 8 can for example be printed on the carrier foil by means of a conductive paste” and “a depression is manufactured in the carrier foil, e.g.[,] by milling, lasering, etching, before the chip module 10, the antenna coil 8 and optional further electronic devices are inserted into the depression.” Ex. 1007, 13:26–31, 13:35–37. Schröder further describes that “[a]t least one further foil can be applied to the carrier foil or the ring blank on at least one side” to produce a “multilayer foil composite” that can be “interconnected” by means of “glue” slip op. at 23

    “show that Schröder’s inlay 12 is a PCB. Relying on testimony from Dr. Anthony, Petitioner asserts that Schröder’s inlay 12 serves as a flexible carrier made of materials “commonly understood to be printed circuit board materials” such as PET and Kapton. Pet. 23 (citing Ex. 1002 ¶ 172; Ex. 1006, 12:28–29). Dr. Anthony did not provide a clear explanation of a person of ordinary skill in the art’s understanding of a PCB in his direct testimony. article describing a PCB as a “laminated sandwich structure of conductive and insulating layers” was an accurate description of a PCB: Q. So is the first sentence of this Wiki page, in your mind, an accurate description of a printed circuit board? A. So, the first sentence, “A printed circuit board (PCB)[] also called [a] printed wiring board, []is a laminated sandwich structure of conductive and insulating layers, each with a pattern of traces, planes, and other features (similar to wires on a flat surface) etched from one or more sheets of copper laminated onto or between sheet layers of nonconductive substrate.” And so your question again was? Q. Is that a fair definition of printed circuit board in your mind? A. It’s a fair description of the general process for circuit boards, layers of conductive traces.” slip op. at 21
