“In our Institution Decision, we found that Petitioner’s proposal was consistent with the level of ordinary skill in the art reflected by the prior art of record and we preliminarily adopted Petitioner’s unopposed position. Inst. Dec. 8–9 (citing 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)). As neither party challenges our preliminary finding regarding the level of ordinary skill in the art, we see no reason to disturb that finding. Accordingly, we maintain and reaffirm that one of ordinary skill in the art at the time of the invention would have had “a bachelor’s degree in mechanical engineering, electrical engineering, computer science, or a similar field with at least two years of experience in adaptive streaming and content management” or “a master’s degree in mechanical engineering, electrical engineering, computer science, or a similar field with a specialization in adaptive streaming or content management” and that “[a] person with less education but more relevant practical experience may also meet this standard.” See Inst.

“the case law makes clear that “an indefinite article ‘a’ or ‘an’ in patent parlance carries the meaning of ‘one or more’ in open-ended claims containing the transitional phrase ‘comprising’” unless an “extremely limited” exception applies. See Convolve, Inc. v. Compaq Computer Corp., 812 F.3d 1313, 1321 (Fed. Cir. 2016) (quoting KCJ Corp., 223 F.3d at 1356; Baldwin Graphic Sys., Inc. v. Siebert, Inc., 512 F.3d 1338, 1342 (Fed. Cir. 2008)). Here, claim 1 recites the transitional phrase “comprising,” meaning it is open-ended, and, therefore, the usual meaning of “a” as “one or more” would have been expected absent an extremely limited exception. In considering whether an exception applies, our review of the ’515 patent fails to indicate that the patentee intended the phrase to mean anything other than the usual meaning of “one or more.” Patent Owner asserts that “[t]he plain language of the claim clearly indicates only a single [list] is used to list multiple assets” and quotes two portions of the Specification, which state “a list of assets that satisfies criteria” and “a list of assets to which a . . . device is granted access.” PO Sur-reply 12–13 (quoting Ex. 1001, 12:60–67) (citing Ex. 1001, 2:23–34, 3:1–5, 4:21–23, 17:59–66). Although claim 1 of the ’515 patent recites “assets” in the plural, we fail to see how that conveys that the term “a” would have been understood as limited to “one.” Notably, neither party has identified any inconsistency, in the claims or other portions of the Specification (including the portions quoted and/or cited by Patent Owner), resulting from construing “a” as “one or more.” And, we find that there is no reason why the claims could not be met under the construction of “a” as “one or more.” Thus, we find that the ’515 patent does not “evince [ ] a clear intent to limit a or an to one.” See Convolve, 812 F.3d at 1321 (internal quotations omitted). Accordingly, we construe the term “a” in “a list of assets” as “one or more” such that the phrase “a list of assets” means “one or more list of assets.” Considering next the phrase “the list of assets” recited in limitation 1[e], the parties do not dispute that the use of the term “the” means that “the list of assets” refers back to the one or more list of assets retrieved in limitation 1[d] and discussed above. See PO Resp. 1–2; see generally Pet. Reply; PO Sur-reply 5. Similarly, the parties do not dispute that the phrase “the filtered list of assets,” recited in limitation 1[e], refers back to the list of assets resulting from the filtering step of limitation 1[d]. See PO Resp. 3–4; see generally Pet. Reply; PO Sur-reply 5. We agree with the parties that each of these phrases refers back to the previous instance of the recited terms.” slip op. at 15

“motivated to combine these teachings for several reasons. Pet. 21. First, Petitioner contends “the combination is the use of a known technique to improve similar devices because using the capabilities of a client device to choose appropriately formatted content was a well-known technique.” Id. Petitioner asserts that “implementing Marusi’s techniques for organizing multiple representations and choosing among them based upon a client device’s capabilities would predictably function in Pyle’s system, which similarly seeks to target video content based on particular client device types and parameters.” Id. (citing Ex. 1004, 10:57–11:10; Ex. 1003 ¶ 147). Second, Petitioner argues that “detecting a client device’s capabilities based upon client device identifiers was a common and known solution to the problem of supplying information in a format usable by the client device.” Pet. 21. Petitioner contends that one of ordinary skill in the art “would have found it obvious to combine Marusi’s teachings with Pyle because it is one solution, from a finite number of known, and predictable solutions.” Id. (citing Ex. 1003 ¶ 148). Third, with respect to Marusi’s databases, Petitioner contends “[t]he combination of Marusi’s databases to manage the data in Pyle’s system uses a known technique to improve similar systems.” Pet. 21. In particular, Petitioner asserts that one of ordinary skill “would have been motivated to combine Marusi’s database teachings with Pyle because Pyle teaches storing the same content in multiple, different representations.” Id. at 21–22 (citing Ex. 1004, 9:64–10:21). Further, Petitioner argues that “[u]sing a database to store and manage multiple representations of the same data, or even to simply store voluminous data for retrieval, was an extremely well-known and common application of databases.” Id. at 22 (citing Ex. 1003 ¶ 149). Additionally, Dr. Reader opines that one of ordinary skill in the art “would have understood that the teachings of Pyle and Marusi were complementary, and therefore would have been motivated to combine Pyle with Marusi to enhance the efficiency of generating, storing, and delivering multimedia content tailored to the capabilities of particular playback devices.” Ex. 1003 ¶ 150.” slip op. at 27

“Patent Owner that Petitioner and Dr. Reader fail to explain why one of ordinary skill in the art would have understood that Pyle generates a top level index file by placing a manifest file in memory for transmission to a client device. Pet. 35; see Ex. 1003 ¶ 184. “Opinions expressed without disclosing the underlying facts or data may be given little or no weight.” Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 2019) (“Consolidated TPG”), 40–41, available at https://www.uspto.gov/sites/default/files/documents/tpgnov.pdf (citing Rohm & Haas Co. v. Brotech Corp., 127 F.3d 1089, 1092 (Fed. Cir. 1997)). Here, there is no explanation or reason given for Petitioner’s assertion or Dr. Reader’s testimony and the connection, if any, is not otherwise apparent. Further, aside from Dr. Reader’s unexplained position, Petitioner has not pointed us to any evidence of record supporting the argument that one of ordinary skill in the art would have understood that placement of a file in memory for transmission teaches generating the file as recited in limitation 1[f]. Accordingly, without any explanation whatsoever, the record is without a sufficiently supported basis upon which to make that finding, resulting in a failure of proof by Petitioner with respect to claim 1.11 10 We also note that Petitioner’s Reply does not seek to add a new argument for our consideration; rather, Petitioner’s Reply asserts, albeit incorrectly, that the argument was raised in the Petition. See Pet. Reply 15. 11 Although Petitioner’s Reply sets forth several arguments in response to other arguments raised in Patent Owner’s Response, those additional arguments do not address to this aspect of limitation 1[f]. See, e.g., Pet. c. Dependent Claims 4, 5, 8–10, and 14 Petitioner contends that the combination of Pyle and Marusi would have rendered the subject matter of claims 4, 5, 8–10, and 14 obvious to one of ordinary skill in the art. Pet. 36–41. Claims 4, 5, 8–10, and 14 depend from claim 1 and, therefore, include limitation 1[f], as discussed above. Accordingly, for the same reasons discussed with respect to claim 1, Petitioner’s analysis of these claims suffers from the same deficiency.” slip op. at 34

“’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

“We are not persuaded by this reasoning. 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. Ex. 1014, 6. We see no compelling reason to excuse the inconsistency by adopting a narrower construction when the Board applies a claim-construction standard (broadest reasonable interpretation) that could only result in the same or a broader construction. See Amazon.com, Inc. v. Barnesandnoble.com, Inc., 239 F.3d 1343, 1351 (Fed.

“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. ¶ 33). 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. at 16 (emphasis added). Patent Owner argues that Gerten does not disclose a selection kernel capable of maintaining synchronization between a master and more than one slave in a piconet, with the master and one slave using a default set of channels while the same master and a different slave use a different set of channels. Id. We are not persuaded that the absence of a specific teaching of such a selection kernel supports the conclusion that one of skill in the art would understand Gerten to function in the manner Patent Owner suggests. 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). 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. (emphasis added). Patent Owner argues that Gerten does not disclose a selection kernel capable of maintaining synchronization between a master and more than one slave in a piconet, with the master and one slave using a default set of channels while the same master and a different slave use a different set of channels. Id. We are not persuaded that the absence of a specific teaching of such a selection kernel supports the conclusion that one of skill in the art would understand Gerten to function in the manner Patent Owner suggests. 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. ¶¶ 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

The term “vote” is not defined in the Specification of the ’624 patent. In the Institution Decision, we applied a preliminary construction of “votes to use the particular communications channel” as “expressions of preference for using the particular communications channel,” a construction that rejected Petitioner’s further proposal that the phrase alternatively encompasses indications whether the communications channel is “good or bad.” Dec. 7– 8. The parties do not present arguments that cause us to reconsider that aspect of the construction. Patent Owner “submits that ‘votes to use the particular communications channel’ should be construed to mean ‘expressions of preference of participants for using the particular communications channel,’” with underscoring to indicate words it proposes to add to the Board’s preliminary construction.

Patent Owner contends that “all of the embodiments” discussed in the Specification of the ’624 patent “are limited to originating from participant devices involved in the communications and are intended to be used to determine the best channels for communication among those same participants.” Id. This contention is not disputed by Petitioner, and we find no counter examples in the Specification.

“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. ¶ 33). 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. (emphasis added). Patent Owner argues that Gerten does not disclose a selection kernel capable of maintaining synchronization between a master and more than one slave in a piconet, with the master and one slave using a default set of channels while the same master and a different slave use a different set of channels. Id. We are not persuaded that the absence of a specific teaching of such a selection kernel supports the conclusion that one of skill in the art would understand Gerten to function in the manner Patent Owner suggests. 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, 63. 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. 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.

“Nor are we persuaded by Patent Owner’s contention that Gerten teaches away from the claim limitations. See PO Resp. 15. A prior-art reference does not teach away from the claimed subject matter unless the prior-art reference also criticizes, discredits, or otherwise discourages the solution claimed. See In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004). In support of this contention, Patent Owner relies on testimony by Dr. Melendez that “the only selection kernels (Gerten Fig. 6 and Fig. 7) disclosed for the transceiver (Gerten Fig. 2) in Gerten are expressly not capable of providing the subject claimed limitations of the [’]624 patent as is discussed below, and so would serve only to teach away from the claim.” Melendez Decl. ¶ 33. Even if Dr. Melendez’s statement is accurate, such examples in Gerten do not meet the “teaching away” standard because the mere use of examples in a reference that function in a different way does not criticize, discredit, or otherwise discourage the solution claimed. In addition, “[t]eaching away is irrelevant to anticipation.” Seachange Int’l, Inc. v. C-Cor, Inc., 413 F.3d 1361, 1380 (Fed. Cir. 2005).” slip op. at 19

“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
