    “Qualcomm contends, citing Dr. Larson’s testimony, that one of ordinary skill in the art as of October 1998 would possess, at a minimum, either (a) a master of science degree in electrical engineering and two or more years of experience in radio frequency circuit design, or (b) a bachelor of science degree in electrical engineering with three or more years of experience with the design and development of RF circuits. Pet. 10–11 (citing Ex. 1002 ¶¶ 31–39). ParkerVision does not contest Qualcomm’s designation of the level of ordinary skill in the art as of the date of the invention. Accordingly, we adopt Qualcomm’s proposed level of ordinary skill in the art.” slip op. at 11

    “During the trial, ParkerVision asserted that we should maintain our construction of “harmonic” (PO Resp. 19–23), and Qualcomm did not address the adopted construction. With respect to the remaining terms, ParkerVision argues that none of these terms are material to the remaining dispute between the parties, which is focused on the “harmonic” limitation. Id. at 24–25. On this, we agree. As the remaining terms are not material to the parties’ dispute, we decline to construe them further. See Vivid Techs., Inc. v. Am.

    “Regarding the Maas equation, ParkerVision directs us to a portion of Dr. Larson’s deposition, in which Dr. Larson used the Maas equation to calculate the harmonics produced by a mixer, given certain assumed inputs supplied by ParkerVision’s counsel (an input signal of 100 kHz and an LO input of 1 MHz). Id. at 29–31 (citing Ex. 2001, 177–87). ParkerVision notes that Dr. Larson’s calculations produced -0.9, 3.1, and -4.9 MHz as the first three harmonics, which are not integer multiples. PO Resp. 31. Thus, ParkerVision argues, the circuit of Nozawa does not necessarily produce a plurality of harmonics, defined by the ’940 patent as being integer multiples of the fundamental frequency. Id. Qualcomm argues that the Maas equation “shows that Nozawa will necessarily produce the required ‘integer multiple’ harmonics for many input frequencies.” Pet. Reply 4 (emphasis added). According to Qualcomm, it is not required to show that Nozawa will produce integer multiple harmonics for all operating conditions; rather, it is only relevant that Nozawa could be operated to produce the harmonics. Id. Regarding Dr. Larson’s calculations during his deposition, Qualcomm contends that even using the assumed inputs provided by ParkerVision, the Maas equation shows that the 35th and 37th harmonics are 35.1 and -36.9 MHz, respectively, which are integer multiples of the fundamental frequency of 0.9 MHz. Id. at 7. Qualcomm also notes that selecting slightly different input frequencies for the Maas equation will produce much lower integer multiple harmonics, such as at the 7th and 9th harmonics. Id. at 8. The parties’ disagreements over the various inputs and permutations of the Maas equation aside, one point appears to be beyond dispute: under some conditions, but not all conditions, the Maas equation shows that Nozawa’s structure will produce a periodic signal that contains integer multiples of the fundamental frequency. In other words, the structure of Nozawa is capable of producing a signal that satisfies the limitations of the claim. Qualcomm argues that this is sufficient to show unpatentability. Pet. Reply 13 (citing Gen. Electric Co. v. Jewel Incandescent Lamp Co., 326 U.S. 242, 248–49 (1945)). On this point, we agree. Claim 21 and its dependents are apparatus claims; as such, they “cover what a device is, not what a device does.” Hewlett-Packard Co. v. Bausch & Lomb Inc., 909 F.2d 1464, 1469 (Fed. Cir. 1990). In other words, the “periodic signal” limitations, which are directed to the transitory electrical signals produced by the apparatus, cannot give rise to patentability so long as the underlying apparatus has been shown to be capable of generating those signals. Here, it is undisputed that Nozawa’s circuit is capable of generating a periodic signal having a plurality of harmonics, wherein those harmonics are integer multiples of the fundamental frequency. Furthermore, we agree with Qualcomm that Nozawa’s low-pass filter is capable of isolating one or more of those harmonics, as desired.” slip op. at 16

Indeed, as Qualcomm observes, the 74HC4052 chip described in Philips 4052 is used in Nozawa. Id. at 28–29. We agree with Qualcomm that a person of ordinary skill in the art would have had reason to look to the disclosure of Philips 4052 to learn more about the operation of the 74HC4052 chip disclosed in Nozawa. ParkerVision does not challenge that a person of ordinary skill in the art would have combined Nozawa with Philips 4052.” slip op. at 12

    “We do not find Patent Owner’s arguments persuasive. Teaching away requires that “a person of ordinary skill upon reading the reference, would be discouraged from following the path set out in the reference, or would be led in a direction divergent from the path that was taken by the applicant.” In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994).4 Patent Owner cites nothing in Yamashita that says that adding the features from Shamoon in addition to the automatic functionality of Yamashita would be unlikely to work; Yamashita alleges only that manual control alone has certain disadvantages. 4 We understand Patent Owner to be arguing both that the references teach away from the combination generally and teach away because, in particular, the combination would change the principle of operation of the system. PO Resp. 33–36. See In re Mouttet, 686 F.3d 1322, 1334 (Fed. Cir. 2012); see also Baxter Int’l, Inc. v. McGaw, Inc., 149 F.3d 1321, 1328 (Fed. Cir. 1998) (finding no teaching away where nothing in the prior art device suggested that the claimed invention was unlikely to work). The lack of teaching away is confirmed by Yamashita’s disclosure of an embodiment requiring manual interaction. See Reply 20 (citing Ex. 1006, 22:31–51). Indeed, although Patent Owner contends that automatic functionality is “not the focus or main purpose of Shamoon,” PO Resp. 35, Shamoon’s system demonstrates that automatic functionality can be combined with manual functionality to result in a working system. See Ex. 1007, 8:36–45. As for Patent Owner’s contentions that Yamashita “abandoned bi- directional communication” (PO Resp. 35), we find no support in the cited portions of Yamashita for these contentions. Although Yamashita does tout the benefits of its automatic control system, the cited portions of Yamashita are silent about the advantages or disadvantages of “bi-directional communication.” As for Patent Owner’s arguments about substantial reconstruction and redesign (PO Resp. 36 (citing Ex. 2008 ¶ 91)), we do not find the testimony or argument persuasive. Yamashita’s control terminal and mobile terminals already has built in communication abilities (Ex. 1006, 11:31–38), and we find Dr. Selker’s testimony persuasive that a person of ordinary skill would have been motivated to add the ability to communicate the thermostat reading to verify that Yamashita’s automatic control worked. Ex. 1002 ¶¶ 205–207. As for Patent Owner’s allegation that the combination with Shamoon would change Yamashita’s principle of operation, we disagree. Yamashita would continue to work as before; the messages, rules, and control information would continue operate in the same manner. Shamoon would only add additional functionality to allow for an improved user interface and two-way communication. Where the device would operate on the same principles as before, the combination does not change the principle of operation. See Mouttet, 686 F.3d at 1332 (noting Ratti inapplicable where the modified apparatus will operate “on the same principles as before”). As Petitioner explains, Shamoon demonstrates that its known techniques have been used to improve similar devices in similar ways. We find that Petitioner has articulated sufficient reasoning with rational underpinnings to support the combination. See Ex. 1002 ¶¶ 205–207, 213. Thus, we conclude that a person of ordinary skill would have had reason to combine the teachings of Yamashita and Shamoon.” slip op. at 29

First, the parties dispute whether the mobile device must be able to transmit location information to the site regardless of whether the proximity setting is enabled or disabled. See Reply 8–9; PO Resp. 14–15. Second, Patent Owner argues that the entire process of proximity detection must be automatic. PO Resp. 14. As we explain below, we agree with Petitioner that this term does not require that the mobile device continue to send location reports if the proximity setting is not enabled, whereas we disagree with Petitioner that the proximity setting is limited to enabling or disabling the ability to send location reports. Instead, we find the specification supports a broader construction. In particular, we find that the specification states that “[f]or example, a user may enable proximity detection using proximity detection selector 1036 and energy use at a site may be altered based on a user[’]s distance to the site.” Ex. 1001, 46:45–48.

Thus, we consider the broadest reasonable construction of “proximity setting” consistent with the specification to be “a setting that can enable or disable proximity detection, where energy use at a site may be altered based on the user’s location.” Both parties acknowledge that this is a reasonable meaning of the term.

In particular, we do not agree with Patent Owner that Yamashita teaches away from the combination or that the combination would change the principle of operation of Yamashita.3 Patent Owner is correct that Yamashita distinguishes manual control, and notes the disadvantages of “burdensome operations” and the possibility the user may forget to perform the required operations.

Patent Owner is also correct that Yamashita states that one objective of the invention is a system that can automatically control an appliance based on position without requiring any operation by the user.

As Petitioner observes, the embodiments of the ’624 patent identified by Patent Owner are characterized as “examples,” and a person of ordinary skill “would understand that the example scenarios of the specification are not necessarily limiting on the claims.” Reply 3 (citing Ding Supp. Decl. ¶ 6). In addition, Petitioner notes that claim language in related patents owned by Patent Owner explicitly refers to participants, evidencing Patent Owner’s understanding “how to expressly create participant-specific voting requirements in claims.” Id. at 3. At the oral hearing, Patent Owner suggested that explicit reference to participants in such other claim language “was because it wanted to clarify that each participant got a single vote,” and explained its position that, in the claims at issue in this proceeding, “participant is implicit in the claim language as it is.” Tr. 78:16–25. But the claims are directed to a “communications apparatus,” and recite “votes” in the context of what the “particular communications channel” “receives.” Nothing within the structure of the claims requires resolving the origin of such votes. Furthermore, Patent Owner’s proposed construction is inconsistent with the construction it agreed to before the district court in the Qualcomm Litigation. In that litigation, the parties agreed that the term “vote” should be construed as “a binary expression (to use or not to use),” a construction that makes no reference to the origin of the “vote” as from a participant or otherwise.

In this instance, Petitioner refers to two embodiments of Gerten “in which a first participant communicates with a second participant via a normal sequence and with another participant via an adaptive hopping sequence.” Reply 5. First, Figure 3 of Gerten is reproduced below. Figure 3 illustrates “methodology for determining and communicating channels to be avoided to a remote device.” Ex. 1003, col. 2, ll. 4–6. As illustrated in the drawing, a master unit performs a discovery process (block 110) upon connecting with a new slave unit. Ding Decl. ¶¶ 60, 64. If the slave unit is capable of using interference avoidance, the master unit begins the process of determining a modified set of channels for use (block 120). Id. ¶ 45. If a second slave unable to use interference avoidance enters the piconet, standard frequency hopping is used. Supp. Ding Decl. ¶ 9. Under Patent Owner’s characterization of Gerten, entry of the second slave into the network would require the first slave necessarily to revert back to the default hopping sequence. Id. ¶ 10. But this would undermine the stated benefits of Gerten, which explicitly discloses: The above process can be applied to a Bluetooth example and includes identification of a Bluetooth device’s ability to support interference avoidance, the measurements of signal strength on all channels and identification of which channel should not be used without violating the FCC rules, a method of modifying the Bluetooth hop sequence so that it will avoid channels containing strong or fixed interferers while still supporting standard Bluetooth hopping with other non-enabled members of the piconet and a method of relating necessary interference avoidance information to the remote Bluetooth devices.

    “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).

As illustrated in the drawing, a master unit performs a discovery process (block 110) upon connecting with a new slave unit. Ding Decl. ¶¶ 58, 61. If the slave unit is capable of using interference avoidance, the master unit begins the process of determining a modified set of channels for use (block 120). Id. ¶ 46. If a second slave unable to use interference avoidance enters the piconet, standard frequency hopping is used. Supp. Ding Decl. ¶ 9.

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. That Cuffaro incidentally uses different frequencies for uplink and downlink communications does not diminish the relevance of the teaching identified by Petitioner.” slip op. at 23

In doing so, Petitioner notes that Gerten discloses periodic updating of the modified frequency hopping scheme, supporting a conclusion that Gerten discloses selection at different times. Id. at 14, 15– 16. Petitioner highlights this periodic updating to identify distinct “period[s] of time” during which different “set[s] of two or more communications channels [are] used to transmit and receive.” Id. at 15–16 (italics omitted). In addressing independent claim 1’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 18 (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. at 18 (citing Ding Decl. ¶ 55); see id. at 16–17. Thus, Petitioner concludes, the recited transmissions and receptions from the third communications device over default communications channels occur “while” transmitting to and receiving from 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.

But the claims are directed to a “communications device,” and recite “votes” in the context of what the “particular communications channel” “receives.” Nothing within the structure of the claims requires resolving the origin of such votes. Furthermore, Patent Owner’s proposed construction is inconsistent with the construction it agreed to before the district court in the Qualcomm Litigation. In that litigation, the parties agreed that the term “vote” should be construed as “a binary expression (to use or not to use),” a construction that makes no reference to the origin of the “vote” as from a participant or otherwise.

    “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.
