      “We are persuaded by Patent Owner’s argument that claim 1 is not obvious over Avellan because it does not assemble a media stream of multimedia items using the recited screen captures. See PO Resp. 21–23. We agree with Patent Owner that the plain language of the claim requires more than transmitting individual media items. PO Sur-reply 20. To the extent that Avellan captures images, those images do not meet the claimed requirements for a “temporal sequence of screen captures” in the independent claims, which must (1) be of the web page rendered by a browser, (2) “define all the content of the web page at a given time,” (3) “illustrate a dynamic change of at least a portion of the content over time” when two of them are compared, and (4) used to assemble “the at least one media stream.” Rather, the record better supports Patent Owner’s argument that Avellan transmits the multimedia items separate from any media stream assembled from screen captures.

      “’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.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for petitioner

      “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

      “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.

      “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.

      “interpretation of the language used in claim 1 and the additional limitations of dependent claims 9 and 10. Patent Owner’s proposed construction also impermissibly reads limitations from the preferred embodiment of Figure 5 into claim 1. Patent Owner would limit the pilot hole location exclusively to a position directly over the implant position and require the drill bit to pass through the pilot hole while drilling a bore hole into the patient’s jaw. The language recited in claim 1, in the context of the ’006 specification, does not so-limit the “determinating a pilot hole” step. First, Patent Owner fails to consider the present participle form “determinating”5 at the beginning of the recited method step at issue. As a result, Patent Owner conflates the recited device production step with a specific process for drilling a bore hole into a patient’s jaw during tooth implant surgery. PO Resp. 14–15. For example, Patent Owner relies on Dr. Erickson’s Declaration testimony (and Dr. Benjamin’s deposition testimony) for the proposition that “pilot hole” is a term of art referring to “an initial hole through which a pilot drill passes during an operation.” Ex. 2002 ¶ 37 (cited at PO Resp. 16–17); see also PO Resp. 16–17 (citing Ex. 2023, 24:3– 22, 25:18–27:2, 52:2–9). The ’006 patent does not describe or reference any such “pilot drill” or “initial hole” being made during a tooth implant operation. Regardless, the claim limitation at issue is a step in a method of producing a drill template. It recites defining a pilot hole in a drill template with reference to the surfaces of neighboring teeth, nothing more.

More particularly, Bannuscher discloses the desire to obtain “all the necessary [clinical] parameters” relevant to pre-surgical implant planning, which can be “combined together” (“correlated” in the language of claim 1) using planning simulation software, for transfer to a drill template. Ex. 1010, 5:44–6:13, 6:24–40, 7:38–8:4. As Dr. Erickson testified, it would have been desirable for a POSA to have as much diagnostic information as possible when planning for dental implant surgery. Ex. 1029, 31:12–21. Truppe discloses the advantage of correlating three-dimensional X-ray imaging data of the jaw and optical imaging data of the jaw and teeth, using simulation software, to obtain a “vivid” representation. Ex. 1008, 2:7–16, 3:19–28, 3:56–58; 4:1–5. Truppe, therefore, discloses a similar process to that disclosed in Bannuscher with respect to correlating 3-D X-ray imaging data and 3-D optical data representing the surfaces of the jaw and teeth, to generate the best possible representation of the patient’s jaw and teeth. Ex. 1002 ¶¶ 89–92. A POSA would have been motivated to use Truppe’s optical measurement system to generate 3-D surface data of the jaw and teeth for use in Bannuscher’s planning simulation software, in order to produce an enhanced image for determining the optimal bore hole and pilot hole in the drill template. Id.; Ex. 2023, 186:8–187:13 (“the optical imaging [of Truppe] would basically just enhance the diagnostic data [of Bannuscher]”). For example, a POSA would have optically measured the plaster model of the jaw and teeth referenced in Bannuscher and the patient’s actual jaw and teeth, as in Truppe, to produce a “vivid” image for correlation with the X-ray imaging data. Ex. 1002 ¶¶ 89, 92.20 Bannuscher’s determination of the optimized bore hole and corresponding pilot hole in the drill template would be based on the enhanced imagery generated from the correlated 3-D data sets. In short, we are persuaded that a POSA would have had reason to incorporate the teaching of Truppe’s enhanced 3-D optical measurement technique into Bannuscher’s method for correlating 3–D X-ray image and model geometry data sets, to determine an optimal bore hole and corresponding pilot hole in the drill template. For the reasons given above, we are persuaded that Petitioner has established a sufficient motivation for a POSA to combine the relevant teachings of Bannuscher and Truppe, with a reasonable expectation of success, by a preponderance of the evidence.” slip op. at 40

      “We are persuaded by Signal’s arguments. “Distinctive” ordinarily means “characteristic of one person or thing, and so serving to distinguish it from others.” Distinctive, NEW OXFORD AMERICAN DICTIONARY (1st ed. 2001) (Ex. 3001). Accordingly, the plain and ordinary meaning of the limitation “distinctive codes for tire transmitters and vehicle function transmitters” must reflect that the recited codes distinguish tire transmitters from vehicle function transmitters. This is consistent with the surrounding language of claim 1, which recites different actions taken depending on whether the transmitted data contains “a distinctive code for tire transmitters” or “a distinctive code for the vehicle function transmitters.” This usage within the claim is important because “the claims themselves provide substantial guidance as to the meaning of particular claim terms.” Phillips, 415 F.3d at 1314. In particular, “the context in which a term is used in the asserted claim can be highly instructive.” Id. We also note that FCA’s proposed interpretation would read out language from the claim. Under FCA’s theory, the claim does not require the codes to distinguish between tire transmitters and vehicle function transmitters, and encompasses codes that are merely distinct from each other. In effect, FCA would have us read the limitation as “the remote transmitters all having the same data format but distinctive codes.” The claim does not stop there, however. The full limitation is “the remote transmitters all having the same data format but distinctive codes for tire transmitters and vehicle function transmitters” (emphasis added). Thus, the codes are distinctive “for” tire transmitters and vehicle function transmitters, and the processor performs different actions depending on whether the transmitted data contains “a distinctive code for tire transmitters” versus “a distinctive code for vehicle function transmitters.” FCA’s proposed interpretation would read out this important aspect of the claim. Interpreting the claim to require the codes to distinguish between the two types of transmitters also is consistent with the Specification. We agree with Signal that the usage of “distinctive codes” in claim 1 is supported by the Specification’s disclosure of an exemplary message format with a “header” that “identif[ies] the source as a tire sender or a keyless entry fob.” Ex. 1001, 4:51–55, Fig. 4. Importantly, the header is separate and distinct from the “unique transmitter identification code,” an identifier unique to each transmitter that corresponds to the “ID” block in Figure 4. Id. at 4:55– 56, Fig. 4. In other words, the Header distinguishes types of transmitters (i.e., a tire sender or keyless entry fob) by their function or category, whereas the ID uniquely identifies a particular transmitter and distinguishes it from the others. An exemplary use of the ID block is illustrated with respect to step 94 of Figure 7, and it serves to show the different uses of the Header and the ID: After a message is determined to be a tire pressure message via category identification at step 78, a low pressure warning may be displayed “for the particular tire position which sent the message as determined by the identification code incorporated in the transmission,” among other things.

      “In addressing independent claim 9’s specific requirement that different sets of channels be used with the second and third communications devices, Petitioner reasons that the process summarized above may be applied by the master device to each of the slave devices separately: “the master device of Gerten performs a service discovery request to determine if each slave device has interference avoidance capabilities.” Id. at 19 (emphasis added) (citing Ding Decl. ¶ 53; Ex. 1003, col. 4, ll. 38–51). Thus, Petitioner argues, if one slave has such interference avoidance capabilities, communications with that slave may take place using a modified frequency hopping scheme; if another (legacy) slave lacks such interference avoidance capabilities, communications take place using a normal mode with default communications channels that are not changed based on channel performance. Id. (citing Ding Decl. ¶ 54); see id. at 17–18. Thus, Petitioner concludes, the recited communications with the third communications device over default communications channels occur “while” communicating with the second communications device over the first and second sets of communications channels, as we have construed the term “while.” Petitioner supports this reasoning with testimony by Dr. Ding, which we credit. Id. at 19–20 (citing Ding Decl. ¶¶ 52–54). Patent Owner responds that “the Gerten device is not capable of and expressly teaches away from performing this functionality.” PO Resp. 15 (citing Melendez Decl. ¶ 32). Patent Owner contends that “Gerten’s disclosure is directed toward eliminating channels for use in an entire piconet as opposed to eliminating channels for use by certain participants within a piconet.” Id.

Because Cuffaro does not limit the type of communications link used for such reporting, Petitioner reasons, and we agree, that “one skilled in the art would consider it obvious for the slave device in Gerten to perform the interference signal strength measurements” and to communicate channel performance data measured by the slave device over one or more of the plurality of communications channels based on the hopping sequence. Pet. 29. Petitioner supports this reasoning with declaration testimony by Dr. Ding. Ding Decl. ¶ 100. Petitioner further provides persuasive reasoning why a person of ordinary skill in the art would have combined the relevant teachings of Gerten and Cuffaro, including that “Cuffaro and Gerten are in the same field of endeavor” of selecting channels to avoid interference in a communications system; that measuring interference signal strength at a slave device such as described by Cuffaro provides a more accurate determination of the impact of the receiver unit from the interference on a given channel, and, therefore, would provide more accurate identification of bad channels in Gerten; and that Gerten suggests such a modification by describing that both a master and a slave can participate in identifying channels to avoid. Pet. 29–31. Petitioner supports this reasoning with declaration testimony by Dr. Ding. Ding Decl. ¶¶ 101, 102. Patent Owner responds by observing that, unlike Gerten, “Cuffaro does not relate to communications systems wherein the devices that are communicating with each other . . . are even transmitting or receiving on the same channels.” PO Resp. 21. Instead, the cellular telephone systems described by Cuffaro use separate physical channels for uplink and downlink. Ex. 1004, col. 4, ll. 9–11. Patent Owner contends that, in Cuffaro, performance data cannot be sent back on the same set of channels on which they were received, and, therefore “[a] mobile station of Cuffaro cannot transmit channel performance data ‘over one or more of the plurality of communications channels.’” PO Resp. 21–22. Dr. Melendez agrees. Melendez Decl. ¶¶ 41–43. Even accepting that Patent Owner’s contention regarding Cuffaro is factually accurate does not lead to the conclusion that Petitioner’s reasoning regarding the combination of Gerten and Cuffaro is deficient. Petitioner does not propose simply to incorporate the performance-data communication mechanism of Cuffaro into the system of Gerten. Rather, Petitioner relies on Cuffaro’s teaching of communicating performance data between devices, and applying that teaching to the system described by Gerten. See Reply 9– 10.

We are not persuaded by this reasoning.

      “Petitioner further provides persuasive reasoning why a person of ordinary skill in the art would have combined the relevant teachings of Gerten and Cuffaro, including that “Cuffaro and Gerten are in the same field of endeavor” of selecting channels to avoid interference in a communications system; that measuring interference signal strength at a slave device such as described by Cuffaro provides a more accurate determination of the impact of the receiver unit from the interference on a given channel, and, therefore, would provide more accurate identification of bad channels in Gerten; and that Gerten suggests such a modification by describing that both a master and a slave can participate in identifying channels to avoid. Pet. 30–31. Petitioner supports this reasoning with declaration testimony by Dr. Ding. Ding Decl. ¶¶ 128, 129. Patent Owner responds by observing that, unlike Gerten, “Cuffaro does not relate to communications systems wherein the devices that are communicating with each other . . . are even transmitting or receiving on the same channels.” PO Resp. 21. Instead, the cellular telephone systems described by Cuffaro use separate physical channels for uplink and downlink. Ex. 1004, col. 4, ll. 9–11. Patent Owner contends that, in Cuffaro, performance data cannot be sent back on the same set of channels on which they were received, and, therefore “[a] mobile station of Cuffaro cannot transmit channel performance data ‘over one or more of the plurality of communications channels.’” PO Resp. 21–22. Dr. Melendez agrees. Melendez Decl. ¶¶ 42–44. Even accepting that Patent Owner’s contention regarding Cuffaro is factually accurate does not lead to the conclusion that Petitioner’s reasoning regarding the combination of Gerten and Cuffaro is deficient. Petitioner does not propose simply to incorporate the performance-data communication mechanism of Cuffaro into the system of Gerten. Rather, Petitioner relies on Cuffaro’s teaching of communicating performance data between devices, and applying that teaching to the system described by Gerten. See Reply 9– 10. That Cuffaro incidentally uses different frequencies for uplink and downlink communications does not diminish the relevance of the teaching identified by Petitioner. For these reasons, we Patent Owner makes too broad a general” slip op. at 24

      “1. Level of Ordinary Skill in the Art In our Final Written Decision in IPR 149, we found “that one of ordinary skill in the art would have had a degree in mechanical engineering or industrial design, but also a general understanding of the use of electrical components, which may be incorporated in mechanical designs.” IPR 149 Decision 23. The parties present the same arguments here, with respect to their views of the level of ordinary skill in the art, as they did in IPR 149. Accordingly, for the reasons discussed in our Final Written Decision in IPR 149 we adopt the same level of skill here. Id. at 22–23.” slip op. at 17

      “Second, Dr. Wolfe testified that Matsumiya discloses “a shaft” that protrudes from each side of the case. Ex. 1016 ¶ 97. On cross-examination, however, Dr. Wolfe admitted that while Matsumiya could disclose a “split axle,” “normally, you’d presume that it’s a through axle.” Ex. 2012, 85:9– 18. Dr. Wolfe did not explain in his direct testimony how either an axle or split axle would be integrated with or attached to at least one side of the case. Third, Petitioner relied on the express disclosure of Matsumiya, not a modification of Matsumiya, as teaching this element of the claims. See Pet. 16 (relying only on Matsumiya’s disclosure). In its Reply, Petitioner asserts, for the first time, that Matsumiya “could also use a snap hinge,” pointing to Professor Visser’s cross-examination testimony. Reply 13 (citing Ex. 1050, 127:9–11). Professor Visser’s testimony, however, does not support Petitioner’s argument. Professor Visser testified that Matsumiya does not show a snap-on hinge, and that a snap-on hinge would not have the same functionality as an axle. Ex. 1050, 127:18–21. He also testified that the two concentric rings on the arms of Matsumiya are inconsistent with a snap-on hinge. Id. at 128:17–20. Thus, the issue before us is not whether it would have been obvious to modify Matsumiya to include a snap-on hinge or hinge protuberance on the side of the case because that was not the basis set forth in the Petition and upon which we instituted review; rather, the issue is whether Petitioner has shown that Matsumiya discloses a hinge element or hinge protuberance integrated with or attached to at least one side of the case. In light of the record before us, and as detailed in the discussion above, we conclude that Petitioner has not shown that Matsumiya discloses a hinge element or a hinge protuberance “formed on at least one side of the case.” We find that Petitioner has failed to present sufficient evidence to show that Matsumiya discloses this element of the claims, and we find Patent Owner’s evidence in the form of Dr. Wolfe’s cross-examination testimony and Professor Visser’s testimony more persuasive.” slip op. at 22

      “Id. at 1:14–23. Accordingly, we find that Kindig’s field of endeavor is hinged enclosures to house appliances that make noise when operated. The ’544 patent states that “[t]he present invention relates to a flash memory apparatus, and more particularly to a flash memory apparatus, wherein a cover is not completely separated from the main body upon being in use so that lost [sic] of the cover is prevented.” Ex. 1001, 1:8–11. The ’544 patent is largely directed to a cover that rotates with respect to a case (as is evident from the parties’, and consequently our, extensive discussion of the hinged connection (i.e., hinge protuberances and hinge holes)), but is not readily disconnected. In fact, the ’544 patent discloses the recited “hooking groove” and “hooking threshold” specifically to prevent the hinge hole from being easily detached from the hinge protuberance. Id. at 3:36–43 (“Furthermore, a hooking groove 34 is preferably formed on the lower periphery of the hinge protuberance 33. A hooking threshold 45 is hooked on the hooking groove 34 and is preferably formed on a rim confining the hinge hole 41 in order to prevent the hinge hole 41 from being easily detached from the hinge protuberance 33 after joining of the hinge hole 41 and the hinge protuberance 33.”). Thus, we find that the ’544 patent’s field of endeavor is hinge assemblies for a flash memory apparatus.” slip op. at 32

      “Second, Petitioner asserts that Kindig’s hinge connection “would advantageously help to retain connection between the cover of Matsumiya and the memory card,” id. at 25, but Petitioner has not shown that Matsumiya fails to retain the connection between case and cover or has difficulty doing so. Rather, from our review the record supports that Matsumiya’s cover is securely attached to the case. Additionally, we are unaware of any teaching in Matsumiya of disconnecting the cover from the case. Similarly, the ’544 patent aims to avoid disconnecting the cover from the case, as discussed above. Kindig, however, is directed to an easily detachable cover. Accordingly, Petitioner’s reason—as to why one of ordinary skill in the art would have been prompted to modify Matsumiya by adding the elements of claim 13 from Kindig—lacks a rational underpinning. 3.
