Id. ¶ 71 (citing Ex. 2004, 262). Accordingly, Patent Owner’s argument, that angular momentum cannot be used to detect a vehicle turning, is persuasive. Id.

See Pet. Reply 11. This argument does not satisfy Petitioner’s burden to provide articulated reasoning with some rational underpinning to support the conclusion of obviousness. See KSR, 550 U.S. at 419 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006)). Petitioner does not explain which teaching of Kleppner a person of ordinary skill would have selected and combined with their knowledge of a rotation vector to yield the method of claim 1, or explain why a person of ordinary skill would have recognized based on Kleppner that estimating the angle between a rotation vector and gravity vector could be used to detect a vehicle turning. Nor does Petitioner respond to Patent Owner’s assertion that Kleppner provides no rationale for estimating an angle of alignment between a rotation vector and gravity vector as a way of detecting a vehicle turning.

      “We agree with Petitioner that the ’690 patent does not limit the term “probe” to channel assessment. Pet. Reply 2–4. Reviewing the intrinsic evidence, the “Technical Field” of the ’690 patent states that “some embodiments relate to channel assessment probes,” implying others do not. Ex. 1001, 1:13–14. The ’690 patent further states that “receiver determined probes may be used in a variety of applications” including to “discover hidden nodes” and “off-site network diagnosis.” Id. at 2:20–27. In addition, the ’690 patent states that probes may be used for “network maintenance procedures,” to “replicate a potential problem, reach or discover a distant or previously undetected node on the network, or assist with network admissions procedures.” Id. at 4:25–38. Turning to the claims of the ’690 patent, the evidence of record does not establish that the independent claims recite anything unique or specific to channel assessment (although their scope covers that purpose). Furthermore, dependent claim 7 of the ’690 patent recites that the “probe” is used to diagnose a network problem, and dependent claim 13 recites that the “probe” is used to identify a hidden node. Restricting the independent claims to probes used solely for channel assessment would be contradictory to these dependent claims. Littlefuse, Inc. v. Mersen USA EP Corp., 29 F.4th 1376, 1380 (Fed.

      “We agree with Petitioner that a “physical layer probe” is “a probe that relates to the physical layer.” The term does not appear per se in the specification of the ’960 patent, nor in the prosecution history, but only in claims 9, 17, and 19. However, the term “physical layer” is well-known and is the first layer in the Open Systems Interconnection (OSI) network model. See, e.g., Ex. 1021, 35–40, 69; Ex. 1002 ¶¶ 49–50. The physical layer is used to transmit digital bits over a network, and defines the timing, mechanical, and physical network characteristics required for transmitting the data bits. Hence, a “physical layer probe” is a probe that relates to the physical layer. We need not, and do not, construe the term further to resolve the parties’ dispute. See Realtime, Vivid Techs., supra. Having decided proper constructions for the disputed terms, we proceed in our analysis to consider the parties’ arguments concerning the challenge grounds. In the following sections, we apply the plain meaning of the claim terms, and as necessary, specify what the plain meanings are.” slip op. at 23

      “C. Level of Ordinary Skill in the Art Petitioner contends as follows: A POSITA8 would have had a bachelor’s degree in electrical engineering, computer engineering, or a similar discipline, and three to four years of experience working in signal processing and/or communication systems/networks. Additional education may substitute for experience, and significant work experience may substitute for formal education. Pet. 6 (citing Ex. 1002 ¶¶ 115–120). Patent Owner does not dispute Petitioner’s proposed level of skill in the art. We adopt and apply Petitioner’s proposed skill level because it is consistent with the problems and solutions identified in the ’690 patent and the prior art references asserted by Petitioner. In addition, we find the adopted skill level consistent with the education and experience that a POSITA would have had. See In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

      “3. Analysis Only terms that are in controversy need to be construed, and then only to the extent necessary to resolve the controversy. See Realtime Data, LLC v.

On this record, the parties do not dispute each other’s understanding of the plain and ordinary meaning of these terms, and, based upon the parties’ arguments, we determine that no express construction of the claim terms is necessary to resolve the controversy, but address the parties’ arguments in the context of the prior art below.6” slip op. at 16

      “(1) Whether Kim teaches a “video driver receiving the video signal and generating a video drive signal indicative of the video signal” We are persuaded that Petitioner has shown that the identified portion of Kim’s Figure 10 teaches the recited “video driver” and “generat[es] a video signal.” We find particularly persuasive Petitioner’s annotated comparison of Figure 4 of the ’521 patent as compared to Kim’s Figure 10 (both reproduced above), which illustrates the similarities between the ’521 patent and Kim. See Pet. 25–28. As set forth by Petitioner, Kim’s voltage at node A4 (video drive signal generated by the video driver identified in the dark green box) is supplied to the gate of transistor M31, driving the organic light emitting diode OLED by the video driver circuitry identified in the dark green box, similar to how voltage v(t) 322 (video drive signal) is supplied to the gate of transistor M1 driving the OLED 32 by video driver 32 in Figure 4 of the ’521 patent.

      “such as that it is a “simpler design,” would be “an obvious design choice,” “would simplify material needs and cost,” was “well-known,” was a “trivial design change,” would “provide immunity to power source noise,” and “would allow rejection of other power supply noise, such as drift.” Pet. 68– 70. However, several of these reasons focus on what a person of ordinary skill in the art would have been able to do, rather than what a person of ordinary skill in the art would have been motivated to do at the time of the invention. See Polaris Indus., Inc. v. Arctic Cat, Inc., 882 F.3d 1056, 1068– 69 (Fed. Cir. 2018) (finding problematic that “the Board focused on what a skilled artisan would have been able to do, rather than what a skilled artisan would have been motivated to do at the time of the invention”); InTouch Techs., Inc. v. VGO Commc’ns, Inc., 751 F.3d 1327, 1352 (Fed. Cir. 2014). We find Petitioner’s arguments unpersuasive because they amount to little more than an assertion that the recited limitations could have been easily achieved. We agree with Patent Owner that Petitioner’s proposed modification of Hayafuji is a redesign that appears to be the result of hindsight rather than based upon a persuasive reason for the modification. See Sur-reply 15–18. Petitioner’s argument that the modification involves adding to the functionality of Hayafuji by using an obvious variation of the circuitry Hayafuji already discloses that eliminates both the ripple component and the non-ripple component (see Reply 20–21) supports the conclusion that the proposed modifications were improperly informed by the requirements of the claim. For example, Dr. Kattamis’s testimony describes the proposed modifications, which include removing the ripple component extraction circuit and rewiring the existing circuit. Ex. 1015 ¶¶ 270–273, 321–331. We find that the extent of the proposed modifications is more suggestive of hindsight than obviousness. See Metalcraft of Mayville, Inc. v. The Toro Co., 848 F.3d 1358, 1367 (Fed. Cir. 2017) (“[W]e cannot allow hindsight bias to be the thread that stitches together prior art patches into something that is the claimed invention.”); InTouch, 751 F.3d at 1351 (Fed.

      “’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.

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

See generally id. ¶¶ 28–31. Additionally, neither Patent Owner nor Dr. Micklow argues that the difference in the proposed level of ordinary skill in the art affects the outcome of this proceeding; Dr. Micklow, in fact, states the contrary—that his opinions are the same under either level of skill. See Ex. 2001 ¶ 31.7 Nothing in the full record is sufficient to persuade us that our preliminary finding as to the level of ordinary skill in the art was incorrect. Accordingly, 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 our preliminary finding that the level of ordinary skill in the art at the time of the invention would have been “a bachelor’s degree in mechanics, aeronautics, materials, or a related field of study, or equivalent experience, and at least two years of experience in the development of components of vehicles, or an equivalent amount of relevant work or research experience.” Inst.

      “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. 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. PO Resp. 26. Petitioner argues that the skirt panels in the video were made according to the teachings of Layfield and did include “integral vertical lateral side edges as the connecting mechanism for adjacent panels.” Pet. Reply 19 (citing Exs. 1018, 2003, 2005; Ex. 1004, 18:36–39; Ex. 1010 ¶¶ 63–64; Ex. 1055 ¶¶ 37–38).

      “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. 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.

      “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

      “7. Our Analysis of Claim 1 As we analyze the evidence, Mattaboni’s Figure 4 does not relate to any characteristic of its memories that limits the frequency range of recorded seismic data. Rather, Mattaboni’s Figure 4 is “the product of the manufacturer’s specified response curve for the geophone and the measured transfer function of the preamp and filter blocks of Figure 3.” Ex. 1006, Fig. 4 (caption). Mattaboni discloses that its memories are capable of recording data at 120 times per second, or 60 Hertz, and thus above the 50 Hertz that Patent Owner contends is necessary to record “seismic data.” Regarding Patent Owner’s statements (1) and (2) above, Patent Owner’s declarant does not disclose the underlying facts or data on which these opinions are based, and they are thus entitled to little or no weight. 37 C.F.R. § 42.65(a). Regarding Patent Owner’s statement (3), Mattaboni states that the displacement response peak of its instrument is between 25 and 35 Hertz, which is the most important range for microearthquakes. Ex. 1006, 5. Mattaboni, however, also states the effective frequency band of the disclosed instrument is “from about 2 Hz to somewhat over 50 Hz (Figure 4).” Id. at 5. Thus, Mattaboni’s instrument records signals “somewhat over 50 Hz” which is “at least above 50 Hz” and in the frequency range which Patent Owner’s declarant contends is needed to record “seismic data.” Ex. 2051 ¶ 35; Ex. 1104, 301:5–302:1 (testifying that 8–50 Hz range is minimum for “seismic data” under Patent Owner’s construction).” slip op. at 28

      “Petitioner contends there is a “heavy presumption” that claims terms have their ordinary meaning (CCS Fitness, Inc. v. Brunswick Corp., 288 F.3d 1359, 1366 (Fed. Cir. 2002)), and that Patent Owner did not overcome this presumption with a clear and precise definition (In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994)). Reply 8. Claim terms must be construed, however, in light of the specification. See In re Translogic Tech., Inc., 504 F.3d at 1257. In the Specification, the 761 Patent describes “seismic data” as resulting from an acoustic signal from a seismic energy source that propagates into the earth and is partially reflected at subsurface lithologic or fluid boundaries and is detected and recorded as seismic energy data by seismic receivers. Ex. 1030, 1:12–23. Petitioner argues that this passage of the 761 Patent does not mention “seismic data.” We note, however, that this passage does mention “seismic energy data” which is shortened to “seismic data” when mentioned later in the 761 Patent. See, e.g., Ex. 1030, 2:48–51, 3:17–19, 3:26–30, 3:35–40, 3:61–63, 9:41–63. Petitioner further contends that several publications establish that “seismic data” is not limited to the oil and gas industry, but may be used in other fields such as earthquake monitoring. Reply. 10 (citing Exs. 1112– 1114, 1121). Patent Owner argues that its constructions are consistent with, and supported by, other publications from the oil and gas industry. PO Resp. 33 (citing Ex. 2003; Ex. 2004, 213–232). Collectively, these publications establish that the term “seismic data” is used differently in different fields, but the best source for determining the meaning of a claim term is the patent’s Specification. See, e.g., In re Abbott Diabetes Care Inc., 696 F.3d 1142, 1149–50 (Fed. Cir. 2012); In re Suitco Surface, Inc., 603 F.3d 1255, 1260–61 (Fed. Cir. 2010); Vitronics Corp. v. Conceptronic Inc., 90 F.3d 1576, 1583 (Fed. Cir. 1996). As the 761 Patent uses the term “seismic data” consistent with the meaning proposed by Patent Owner, and not the more expansive definition proposed by Petitioner, we adopt Patent Owner’s proposed construction as the correct one to use for our analysis in this decision. The plain meanings of claim terms are construed not in a vacuum, but in the context of the entire patent disclosure. See In re Translogic Tech., Inc., 504 F.3d at 1257. Our construction of “seismic data” and “seismic data recorder” is consistent with the 761 Patent’s use of the terms.” slip op. at 10

      “We agree that Patent Owner’s failure to re-allege the argument in the Response waives the argument that Schmalfeldt is not a “printed publication.” See In re Nuvasive, 842 F.3d 1376, 1380 (Fed.
