    “We agree with Petitioner that the term “3D slices” has no apparent connection to the phrase “direct volume rendering.” Patent Owner’s argument appears to be that DVR “requires an image of the entire anatomical volume that is neither feature-specific nor segmented, [which] would seemingly require that all inner layers be displayed.” Reply 4; see Sur-reply 6–10 (not disputing Petitioner’s characterization). But, as Petitioner notes, the specification directly undermines this by teaching “display [of] a slice of the 3D data instead of a volume of the 3D data.” See Reply 4 n.2 (quoting Ex. 1001, 5:34–35). In other words, to the extent DVR would depict an image of the entire anatomical volume, displaying 3D slices “instead of a volume of the 3D data” implies the opposite of DVR. Even if “3D slices” somehow implied DVR, Patent Owner’s position is still untenable. Claim 1 does not recite “3D slices.” Instead, claim 1 recites “3D data” and “inner layers.” Ex. 1001, 18:54–65. Patent Owner fails to clarify the relationship between “slices,” “3D data,” and “layers,” and its expert even admits that slices and layers are two different things. See PO Resp. 13; Ex. 1022, 32:7–16 (agreeing that the words “slice” and “layer” are not “synonyms”), cited in Reply 4. We also agree with Petitioner that dependent claim 3 distinguishes slices and layers by reciting “slices of the projected inner layer.” Reply 4 (quoting Ex. 1001, 19:3–10). Thus, even if 3D slices somehow implied DVR, the language of claim 1 does not support limiting the claim this way.” slip op. at 12

    “The determination of whether a document was publicly accessible “involves a case-by-case inquiry into the facts and circumstances surrounding the reference’s disclosure to members of the public.” Medtronic, Inc. v. Barry, 891 F.3d 1368, 1380 (Fed. Cir. 2018). For instance, courts routinely rely on the Wayback Machine to determine when a reference was first made available to the public. Valve Corp. v. Ironburg Inventions Ltd., 8 F.4th 1364, 1374 (Fed. Cir. 2021) (“District courts have taken judicial notice of the contents of webpages available through the Wayback Machine ‘as facts that can be accurately and readily determined from sources whose accuracy cannot reasonably be questioned.’”). We disagree with Patent Owner’s argument that “Medivis cannot rely on additional prior art”—Exhibits 1023 and 1024—“that was submitted after its Petition to carry its burden without leave from the Board.” Sur-reply 4. As Patent Owner did not file a motion to exclude these exhibits, we decline Patent Owner’s invitation to disregard them. We also find Petitioner’s Reply argument proper because it directly responds to Patent Owner’s contention that Petitioner did not prove the public accessibility of Amira. See Chamberlain Grp., Inc. v. One World Techs., Inc., 944 F.3d, 919, 925 on issues previously raised.”). Petitioner’s Reply argument appropriately elaborates on the Petition’s contention that Amira was publicly accessible. Patent Owner also does not dispute the substance of Petitioner’s evidence. For example, Patent Owner does not address the substance of Mr. Frank-White’s declaration. We find that this evidence, including Mr. Frank- White’s declaration testimony, persuasively supports the public availability of Amira as of the date shown in the Wayback Machine URL.

    “(4) Analysis We are persuaded by Petitioner’s argument that during the alignment process in Odachi corresponding to claim 13, there is a “spaced distance between the primary inductive coupler [230] and the secondary inductive receptacle 2” which is “reduced gradually and electromagnetic induction occurs between the coupler to the receptacle when the former coupler comes close to the latter receptacle.” Ex. 1005, 6:1–6. Thus, prior to any contact or precise alignment between the two cores, “an electromotive force is induced in the secondary coil 4 and this induced force is increased with the decrease in the spaced distance.” Id. at 6:6–8. At least in that spaced configuration, the evidence of record suggests that primary coil 31 produces a near-field component of flux into free space (the air space between the coils where there is no intervening core material) that is intercepted by secondary coil 4 to effect resonant inductive coupling, and that secondary coil 4 intercepts and receives the near-field component of flux in free space that is generated by primary coil 31 to effect resonant inductive coupling. See Ex. 1032 ¶¶ 48–52, 55. Thus, we find that Odachi discloses a “transmitting antenna” (coil 31) and a “receiving antenna” (coil 4) under Patent Owner’s proposed construction. We would reach the same finding under Petitioner’s proposed broader construction because the evidence suggests that Odachi’s coils 31 and 4 would have been considered “antennas” under the parties’ uncontested definition of that term, which is “a device that radiates and/or receives radio waves.” See id. ¶¶ 43–47, 53–54; Ex. 1032 ¶ 15 (Dr. Allen agreeing with this definition of “antenna”); Ex. 2001 ¶ 25 (Dr. Horenstein agreeing with this definition of “antenna”)). In addition, Petitioner persuasively shows that the free space between Odachi’s coils in the spaced configuration includes the “near-field region,” which includes the induction field around primary coil 31. See Ex. 2006, 498; Ex. 1045, 5:4–7; Ex. 1032 ¶¶ 53–54). Dr. Horenstein’s testimony does not contradict this. Although he points out that there are separate terms for inductive, near, and far fields, he also acknowledges that “[t]he region of space closer to the antenna than the far field is the near-field region.” Ex. 2010 ¶ 37 (citing Ex. 2006, 275).8” slip op. at 22

    “specification support its construction of “formed or mounted to” as encompassing indirect attachment to the substrate. Neither the plain claim language nor the specification requires the phosphor coating to be directly attached to the substrate. Limitation 1(c) recites, wherein the LED chips comprise a phosphor coating to produce a change in a color or a quality of light emitted from the LED chips, wherein the LED chips, the power connection leads, and the phosphor coating are formed or mounted to a flexible substrate that is sufficiently flexible to be formed into a cylindrical shape[.] Ex. 1001, 22:7–12 (emphasis added). The claim is inartfully written, as it requires the LEDs to comprise a phosphor coating but then separately recites that the LED chips and the phosphor coating are formed or mounted to the substrate. But Petitioner correctly explains that the plain meaning requires that “the LED chips comprise a phosphor coating” and that “the [same] phosphor coating” (included in the LED chips) is “formed or mounted to a flexible substrate.” Reply 2. In other words, the use of the term “the” before “phosphor coating” indicates reliance on the antecedent basis of “LED chips comprise a phosphor coating,” and thus the same coating of the LED chips is formed or mounted to the substrate. Logically, by including a phosphor coating with the LED chips, which are formed or mounted to the substrate, the coating of these chips is also indirectly formed or mounted to the substrate. Conversely, it would be illogical to conclude that the claim recites two phosphor coatings, one attached to the LED chips and another attached directly to the substrate, because the structure of the claim refers to a single phosphor coating of the LED chips. Even Patent Owner concedes that the claim encompasses the phosphor coating indirectly being mounted or attached to the substrate (in addition to being directly attached).

    “After considering Patent Owner’s arguments, which we address below, we agree with Petitioner that the combination of Wojnarowski and Martin discloses this limitation and that a person of ordinary skill in the art would have been motivated to combine the references’ teachings in the manner asserted by Petitioner. Briefly, we summarize our findings, and then we address the parties’ arguments in more detail. First, we agree with Petitioner, and Patent Owner does not dispute, that Wojnarowski’s AC input voltage would have been converted to DC voltage in light of the bridge rectifier and capacitor disclosed by Wojnarowski. Pet. 25; Ex. 1002 ¶¶ 119– 20 (citing, e.g., Ex. 1005, 7:59–62, Fig. 24); PO Resp. 35–36 (acknowledging Wojnarowski discloses converting an AC input to a DC voltage). Second, we further agree with Petitioner, and Patent Owner does not dispute, that excessive current due to too few LEDs would have harmed Wojnarowski’s LEDs, and too small a current due to too many LEDs would be insufficient to power Wojnarowski’s LEDs. Pet. 26; Ex. 1002 ¶ 134; PO Resp. 48 (discussing, but not disputing, these assertions).13 Third, we agree that a POSITA would have recognized in view of Martin’s teachings and the knowledge of a skilled artisan that when configuring Wojnarowski’s device, the total forward voltage drop of the series-connected LEDs should approximately match the DC voltage output 13 Petitioner explains the relationship between voltage and current for the LEDs as follows: “the total voltage drop of the circuit would dictate the current drawn by the LED circuitry, which would have been known to be inversely proportional to the voltage.” Pet. 26 (citing Ex. 1002 ¶ 134). of Wojnarowski’s circuit. Pet. 26–27 (citing Ex. 1002 ¶¶ 132–38; Ex. 1008, Abstract (LED voltage “must be matched to the input source voltage”), ¶ 60 (“For AC or any other regularly varying input voltage, there is an additional requirement to direct drive voltage matching”)). For example, Martin teaches that “[t]he number of LEDs in the monolithic array may be selected to achieve a particular voltage drop across each device.” Ex. 1006 ¶ 22. Martin further explains, “[t]he voltage across each of the individual LEDs in the array is the line voltage divided by the number of LEDs in series,” and “[t]he number of LEDs is chosen such that the maximum voltage across each individual LED during the peak in the alternating current cycle is low enough so as not to damage the LEDs.” Id. The forward voltage drop across Martin’s 38 LEDs is about 171 V, which matches Martin’s AC input voltage peak of about 169.71 V. See id. (“At 120 RMS volts, the peak voltage will be about 180V [correction: 169.71 V],” and if the LEDs “can tolerate a maximum forward voltage of 4.5V, at least 38 LEDs connected in series are required.” (38 LEDs x 4.5 V = 171 V)); PO Resp. 41–42 (“While Martin references ‘about 180V,’ both parties agree that the correct value of the peak voltage Vp is 169.71 V.” (citing Ex. 1002 ¶ 127)).

Petitioner responds that the AIA framework permits the use of § 102(e) prior art in IPR proceedings, unlike formerly available covered business method review (CBM) proceedings, which restricted challenges to § 102(a) prior art. Reply 29. We agree. The statute governing the formerlyavailable CBM proceeding explicitly limits challenges based on “prior art that is described by section 102(a).” AIA § 18(a)(1)(C). In contrast, § 311(b) more broadly permits challenges “on the basis of prior art consisting of patents or printed publications.” The broader language in § 311(b) implies that unlike CBMs, IPRs are not limited to challenges solely under § 102(a) prior art. The parties cite to no Federal Circuit decisions that squarely address this issue. However, the Federal Circuit has applied § 102(e) patent application publication prior art in appeals from IPR proceedings. See, e.g., Purdue Pharma L.P. v. Iancu, 767 Fed. App’x 918, 920–21, 926 (Fed. Cir. 2019) (nonprecedential) (determining that a § 102(e) patent application publication was available as prior art in an IPR).

  • Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble limitingDecided for patent owner

    “We agree that the preamble of claim 7 is limiting. The last clause of claim 7 refers back to the preamble and is understood with reference thereto. The last clause states: “means for controlling a function of said apparatus using said information.” Ex. 1001, 26:4–5 (emphasis added). “Said apparatus” derives antecedent basis from the “[h]andheld computer apparatus” recited in the preamble. “Said apparatus” does not refer to “apparatus” in the abstract, dissected from the rest of the term. Moreover, the “means for controlling a function of said apparatus” can be understood because of this reference to the handheld computer apparatus. We disagree with Petitioner that the “handheld computer” portion of the term “[h]andheld computer apparatus” can be ignored. The claim defines the “apparatus” as a “[h]andheld computer apparatus,” and we determine that there is no legal basis for us to dissect this phrase. Petitioner argues that the body of claim 7 only refers to the “apparatus” and not to “handheld computer,” thus “handheld computer” is not essential. But the term is “[h]andheld computer apparatus” not merely “apparatus,” and the body of apparatus.” Thus, we determine that the single term in the preamble, “[h]andheld computer apparatus,” is limiting because it recites essential structure and is “necessary to give life, meaning, and vitality” to claim 7.” slip op. at 9

    “As the Petition does not identify a cell phone in Numazaki as teaching the limitation of claim 11 it cannot show how the Numazaki teaches all of the limitations of the claim. Further, even under Petitioner’s own construction the Petition is deficient. The Petition contains no analysis of how Numazaki’s transmission unit 356 corresponds with the structure of a mobile phone link or equivalents this shortcoming by stating that the “transmission unit” “is part of a ‘TV telephone’ embodiment” in Numazaki; and further arguing that the “transmission unit” is a “functional equivalent for transmitting information.” Reply 22 (emphasis omitted). Notably absent from Petitioner’s argument is an explanation of how the “transmission unit” is a functional equivalent to a mobile phone link. Thus, Petitioner makes no assertion that the transmission unit is the same as or equivalent to the structure Petitioner has identified in the ’431 patent as the relevant structure under 35 U.S.C. §112 ¶ 6. For these reasons, Petitioner has not satisfied its burden with respect to its own claim construction.

    “’026 patent would have had a Master’s degree in Electrical Engineering or Computer Engineering, plus at least two years of experience in integrated circuit design, or alternatively a Bachelor’s degree in one of those fields plus at least four years of experience in integrated circuit design. Pet. 16 (citing Ex. 1102 ¶ 49). In our Institution Decision, we found Petitioner’s proposal consistent with the level of ordinary skill in the art reflected by the prior art of record, see Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978), and, therefore, preliminarily adopted Petitioner’s unopposed position as to the level of ordinary skill in the art. Inst. Dec. 15. Neither Patent Owner, in its Response, nor Dr. Annavaram, in his declaration, proposes a level of ordinary skill in the art. Instead, Patent Owner states that “Patent Owner applies Petitioner’s stated skill level for this response” (PO Resp. 26), and Dr. Annavaram similarly states that “[f]or the purpose of this declaration, I adopt Dr. Harris’ definition of a [person of ordinary skill in the art]” (Ex. 2009 ¶ 24). Nothing in the full record persuades us that our preliminary finding as to the level of ordinary skill in the art was incorrect. Based on the complete record, because our preliminary finding is consistent with the level of ordinary skill in the art reflected by the prior art of record, we maintain and reaffirm that one of ordinary skill in the art at the time of the invention would have had a Master’s degree in Electrical Engineering or Computer Engineering, plus at least two years of experience in integrated circuit design, or alternatively a Bachelor’s degree in one of those fields plus at least four years of experience in integrated circuit design.

    “To the extent Patent Owner argues that these particularized selection clauses recited in different claims must have the same or similar meaning because they all use the word “selecting” (see PO Resp. 28–29), we disagree with Patent Owner. See IGT v. Bally Gaming Int’l, Inc., 659 F.3d 1109, 1117 (Fed. Cir. 2011) (“We caution that claim language must be construed in the context of the claim in which it appears. Extracting a single word from a claim divorced from the surrounding limitations can lead construction astray. Claim language must be construed in the claim in which it appears.” (emphasis added)). The selection clauses recited in these claims are plainly different on the face of the claims when considering the material differences in the claim language set forth above. According the same meaning to the limitations that recite “select . . . based on” indicators, “select . . . when” certain conditions are met, and “select . . . out of a group” of values would be improper because it would blur the material differences in the claim language recited expressly in the claims. Instead, we interpret the selection clauses recited in the challenged claims “in the context of the particular claim in which the disputed term appears” and “in the context of the entire patent, including the specification.” Phillips, 415 F.3d at 1313. In other words, we do not construe the single word “selecting” in isolation, but, rather, interpret the full selection clauses recited in the challenged claims in the context of the entire patent. Claim 13 recites “selecting, by the control circuit, a value of a control signal based on the mode indicator and on the leakage indicator.” In our view, the plain meaning of this limitation is clear on the face of the claim—a value of a control signal is selected based on two indicators, the mode indicator and the leakage indicator.” slip op. at 14

    “Tr. 47:7–23. Because the output of Kim’s NAND gates will be different depending on the value of Kim’s memory cells C1–CN allowed to “pass through,” we agree with Petitioner that the value of Kim’s memory cells C1– CN (the claimed “leakage indicator”) “plays a role” in deciding what the output of Kim’s NAND gates (the claimed “value of the control signal”) will be. Moreover, Patent Owner acknowledged that the output of Kim’s NAND gate is determined based on the inputs to the NAND gates (i.e., the sleep signal input and the memory cell signal input). JUDGE CHUNG: But, knowing a little bit about how a NAND gate works, isn’t it the case that the input to the NAND gates, G1 through GN, with the input of the sleep signal and the C1 through CN signal, isn’t it the case that input to the NAND gate determines what the output is? MS. ZHONG: Okay. So any logic gate, the output will depend on the input. That’s for sure. Tr. 44:18–25; but see id. at 45:3–10 (stating that even if the “output is in control of the input, . . . that does not mean the selection is based on that input”). Thus, we find that Kim’s NAND gate (the claimed “control circuit”) operates to determine its output (the claimed “value of the control signal”) based on its input of the sleep signal (the claimed “mode indicator”) and the memory cell value input (the claimed “leakage indicator”). As discussed in Section III.B, the Specification indicates that “select[ing] the value of the control signal based on the mode indicator and on the leakage indicator” recited in claim 13 is synonymous to determining the value based on the recited indicators. See Ex. 1101, 4:4–11. Thus, the evidence of record shows that Kim teaches “selecting, by the control circuit, a value of a control signal based on the mode indicator and on the leakage indicator,” as recited in claim 13.” slip op. at 44

    “We are not persuaded by Petitioner’s argument and evidence. First, although Petitioner proposes “[s]ubstituting Lee’s inputs of leakage current and temperature for generating a power gate control signal” (i.e., Lee’s “control signal (BIAS)”) for “Kim’s inputs of leakage current and other ‘stimuli’ for generating a power gate control signal” (Pet. 64 (citing Ex. 1102 ¶ 115)), neither Petitioner nor Dr. Harris explains adequately how they are proposing to “substitute” Kim’s control signal with Lee’s “control signal (BIAS).” For example, Figure A reproduced above does not show how Petitioner or Dr. Harris proposes to use Lee’s “control signal (BIAS)” in the proposed combination. Petitioner asserts that “[a]lthough Lee’s control signal is analog and Kim’s control signal is digital, it was well known to apply teachings in an analog domain to a digital domain, and conversions between analog and digital domains were easy to implement.” Pet. 66 (emphases added) (citing Ex. 1102 ¶ 121; Ex. 1115). Dr. Harris similarly states that Figures A and B show examples of obvious ways to use in Kim’s system Lee’s teaching of setting conductance of the array based on temperature. A POSA would have found both of these ways obvious. That Lee uses an analog control signal and Kim uses a digital control signal would have presented no obstacle to a POSA. . . . That is, converting analog circuit elements and signals to digital was well known long before the ’026 patent. Ex. 1102 ¶ 121 (emphases added) (citing (Ex. 1115) (“Analog-to-digital converters (ADC’s) are ubiquitous, critical components of software radio and other signal processing systems.”)). But Dr. Harris does not explain adequately how “to use in Kim’s system” the digitized BIAS signal of Lee. See id. The only additional input signal shown in Figure A compared to Figure 4 of Kim is the temperature line that has the value of 0 when the temperature is cold and the value of 1 when the temperature is hot. See Ex. 1102 ¶ 116 (Fig. A). There is no explanation of how the modified teaching of the BIAS signal of Lee (i.e., modified or converted to a digital signal) would have worked in the proposed combination of Figure A.” slip op. at 69

Pet. 29 (citing Ex. 1010 ¶¶ 102–103).16 We afford this evidence little weight for several reasons. First, the video does not show the strut or the bending of a strut. See Ex. 1018. In fact, the only feature shown is a skirt panel attached to a trailer. that because thermoplastic material is more resilient than aluminum, we should adopt Petitioner’s argument. Pet. Reply 15–16 (citing Ex. 1058, 1– 12; Ex. 1010 ¶¶ 77–82). We must base our decision in this case on the arguments and evidence presented. As explained above, the record before us has contradictory evidence in the form of Dr. Micklow’s testimony that was not before the examiner. 16 Petitioner does not cite Exhibit 1018 in the Petition, but instead cites to Mr. Tres’s testimony regarding the exhibit. Id. Thus, from the video, it is unknown whether the skirt panel is attached to the trailer by one strut, multiple struts, or additional features. Second, Petitioner does not identify clearly how the tested system precisely corresponds to the teachings of Layfield. For example, Patent Owner raises a number of issues with the struts and panels in the video to which Petitioner provides either no response or an unconvincing response. For example, Patent Owner argues that each embodiment of Layfield uses trusses 36 to “interconnect each skirt panel and reinforce the panel assembly,” while it is asserted that the skirt panels in the video do not have trusses and are not interconnected.

    “components (see, e.g., id. at 17:1–10), Layfield does not contain any express disclosure concerning the flexibility of the struts. Nor does Layfield include any discussion about the desirability of strut flexibility. The closest Layfield comes to discussing flexibility of the struts is by frequently referring to the struts as “support struts” (see, e.g., id. at 18:40) and discussing the use of a “bracket means,” which is on the struts, to “rigidly secure” the skirt panels to the trailer (id. at 6:48–49). Further, Layfield’s detailed discussion of the embodiment of support strut 58 shown in Figure 10, reproduced below, highlights the bracing and reinforcement features. Figure 10, above, shows the construction detail of a support strut 58. Ex. 1004, 15:45. Specifically, Layfield discloses that strut 58 includes “a pair of spaced-apart vertical members 160, which are braced by horizontal cross-members 162” and “reinforcing rectangular lattice 170.” Id. at 15:46– 54. Thus, we agree with Patent Owner’s argument that “Layfield does not expressly teach that the ‘support struts 58’ are ‘resilient.’” PO Resp. 42 (citing Ex. 2001 ¶¶ 148–149). We reiterate that Petitioner’s first challenge is based on anticipation. Thus, Petitioner must show that resilient struts are “either expressly or inherently described, in” Layfield. Verdegaal Bros. Inc., 814 F.2d at 631; see also PO Resp. 42. In its Reply Brief and at the oral hearing, Petitioner contends that its challenge is based on express disclosure, not inherency. See Pet. Reply 17–18; Tr. 9:21–11:4 (arguing that “this is not a case of inherency”). Petitioner contends one of ordinary skill in the art “would have understood, based upon Layfield’s express disclosures concerning the material, structure, and connection of the strut, that the Layfield strut is resilient and can sustain significant and substantial elastic deformation.” Pet. Reply 18 (citing REG Synthetic Fuels, LLC v. Neste Oil Oyj, 841 F.3d 954, 960–61 (Fed. Cir. 2016)). Whether we analyze Petitioner’s argument based on express disclosure or inherency, we reach the same result. To begin, although we agree with Petitioner that a prior art reference “need not satisfy an ipsissimis verbis test” (Pet. Reply 17 (quoting In re Gleave, 560 F.3d 1331, 1334 (Fed. Cir. 2009))), there is no express statement that Layfield’s strut is resilient or otherwise exhibits a characteristic synonymous with resiliency. Additionally, we do not agree that Petitioner’s reliance on the thermoplastic materials, disclosed by Layfield for construction of the strut, establishes whether the strut is resilient and capable of elastic deformation. The evidence submitted by the parties is contradictory as to whether one of ordinary skill in the art would have understood Layfield’s struts to be resilient based on the material alone.15 Compare Ex. 1010 ¶¶ 74–82 15 Petitioner also points to a finding by the examiner, during prosecution of the ’017 patent application, that an aluminum strut was resilient, and argues (Mr. Tres opining as to the materials disclosed by Layfield), with Ex. 2001 ¶¶ 160–164 (Dr. Micklow contradicting Mr. Tres’s testimony regarding the materials disclosed by Layfield). Further, the evidence is contradictory as to whether one of ordinary skill in the art would have understood from the design of Layfield’s strut, specifically the taper design and mechanism by which the strut connects to the trailer I-beam, that the strut is resilient. Compare Ex. 1010 ¶¶ 83–90 (Mr. Tres’s testimony regarding the design and connection mechanism), with Ex. 2001 ¶¶ 165–175 (Dr. Micklow’s contradictory testimony). Turning to Petitioner’s video (Ex. 1018), Petitioner asserts testing of commercial versions of the Layfield fairing illustrates what one skilled in the art would have understood from Layfield itself, namely that the Layfield strut is adapted to sustain an elastic deformation when a load is applied to the resilient strut when the skirt panel moves away from the configuration reducing air drag about the trailer and to self-recover the resilient strut original shape when the load is removed.

    “Additionally, Patent Owner similarly contends that the modifications proposed are redundant of Layfield’s “flexible lower panel 20,” which already “allow[s] flexing when impacting a road object.” PO Resp. 59 (citing Ex. 1004, 14:13–18); see PO Sur-reply 26–27. We disagree. Again, the proposed modifications here are to Layfield’s struts. In the context of Petitioner’s anticipation challenge, we agreed with Patent Owner and found that Petitioner had not established sufficiently on the record that Layfield’s struts were resilient. See supra, § II.D.a.i., ii. Therefore, the proposed modification addressed here, to make Layfield’s struts resilient, does not duplicate the objective of Layfield’s flexible lower panel 20 at least because (a) Layfield’s struts are a different structure than lower panel 20 and (b) modification of Layfield’s struts would provide greater impact protection to other panels aside from just lower panel 20. See Pet. Reply 26–27 (One of ordinary skill in the art “would have been motivated to do so because Rinard and Layfield both seek to provide fairing panels with ‘sufficient flexibility’ to bend when encountering objects.” (citing Ex. 1004, 12:67– 13:4; Ex. 1006, 10:43–50; Ex. 1055 ¶ 47)). We determine that Petitioner has shown that one of ordinary skill in the art would have had a reason with rational underpinning to look to other similar types of trailer components that are flexible to make further improvements to Layfield’s design. See KSR, 550 U.S. at 417 (“[I]f a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.”). Third, Patent Owner contends one of ordinary skill in the art “would not have a reasonable expectation of success at achieving the claimed technology by looking to the vertical supports of Rinard’s air scoops to modify the Layfield skirt panels 10 and support struts 58.” PO Resp. 61 (citing Ex. 2001 ¶¶ 237–240). Patent Owner asserts that because Layfield’s upper skirt panels are rigid and non-moving one of ordinary skill in the art “would not reasonably expect the hypothetical modified panels (with their reinforcing trusses 36) to move.” Id. Patent Owner also argues that Rinard teaches “an upper skirt panel that is rigid and non-moving” and so it is not reasonable to expect modifying Layfield as proposed would somehow cause Layfield’s fixed skirt panels to be able to move as claimed. PO Sur-reply 27–28 (citations omitted). We disagree for the same reasons discussed above—namely, we find Layfield’s upper skirt panels to be resilient. Therefore, one of ordinary skill in the art would have a reasonable expectation of success in achieving a resilient strut adapted as claimed by modifying Layfield’s strut in light of Rinard, for the reasons proposed by Petitioner. See Pet. Reply 27 (“Applying this solution to the Layfield skirt panel and struts would yield the predictable result of allowing the Layfield skirt panel 10 and struts 58 to absorb greater impacts without having to be repaired or replaced.” (citing Ex. 1021, 7–8, 11–12)).” slip op. at 42
