    “heart of the parties’ dispute (Ex. 1001, 2:37–45), we determine that the “for instance” phrase is exemplary and does not limit a “conversational flow” to a specific client or user. The phrase “for instance” is synonymous with “for example,” and necessarily indicates that “the running of an application on a server as requested by a client” exemplifies, but does not limit, the conversational flow to a server and a specific client or user. Our determination that the “for instance” phrase is exemplary and non-limiting is consistent with Patent Owner’s argument in its Preliminary Response that the “some” phrase (“some conversational flows involve more than one connection, and some even involve more than one exchange of packets between a client and server”) is non-limiting. Specifically, Patent Owner argued that the use of the word “some” necessarily means that “some conversational flows involve multiple connections, while, some involve a single connection.” Prelim.

Ex. 1001, 4:34–38 (emphasis added). Moreover, the Specification uses the term “mobility” as a capability or condition. For example, the Specification uses the term “mobility” as follows: (i) certain “protocols are not well suited to mobility”; (ii) “[t]he intermediate host might be a Mobile IP home agent, that provides mobility for the connection between the mobile terminal and the home agent . . . .”; (iii) a disclosed “method solves the mobility problem, at the cost of adding extra headers to packets”; and (iv) “[o]ne example of a change in the [security association (‘SA’)] between the first computer and the intermediate computer is the change of addresses for enabling mobility.” Ex. 1001, 5:7–8, 5:17–21, 5:33–34, 7:56–58 (emphases added).

    “After this proceeding was remanded by the Federal Circuit, we invited the parties to address a proposed procedure that would include additional briefing regarding the impact of the prior holdings that claims 1–3, 5, and 10–20 are unpatentable, and the parties filed their respective proposals. Papers 78–80. In its proposal, Petitioner suggested that Patent Owner “has waived the right to address the patentability of claims 4, 8, and 9” because “Patent Owner never separately argued for the patentability of these claims.” Paper 79, 1; see MaxLinear, 880 F.3d at 1378 n.4 (“On remand, the Board may consider whether CRESPE has waived arguments concerning these claims.”). But those claims were not challenged in the earlier proceedings that held claims 1–3, 5, and 10–20 unpatentable. Rather, those claims were only challenged in this proceeding with respect to art that was not at issue in the earlier proceedings. In advancing its contention, Petitioner effectively makes the untenable argument that Patent Owner must provide separate reasons for the patentability of claims 4, 8, and 9, even when we determine that its own case-in-chief for those claims is insufficient. In addition, Petitioner’s proposal requests briefing on the issues of “whether claims 6, 7 and 20 materially alter the [unpatentability] analysis on which the prior [unpatentability] determinations rested.” Id. We have considered, and deny, that request. The Federal Circuit’s remand order noted that the fact that “MaxLinear was not a party to the other IPRs is . . . irrelevant since Cresta, the predecessor in interest to CRESPE, was party to the original determination.” MaxLinear, 880 F.3d at 1377. But the Federal Circuit’s order does not state or suggest that the fact that different prior art was considered in the earlier proceedings is similarly irrelevant. Indeed, we agree with Patent Owner that “[t]he Federal Circuit has not ordered the Board and the parties to start over from scratch, and certainly not with new prior art.” Paper 80, 3; see Ariosa Diagnostics v. Verinata Health, Inc., 805 F.3d 1359, 1367 (Fed. Cir. 2015) (“The Board may control its own proceedings, consistent with its governing statutes, regulations, and practice.”). Patent Owner is correct that “[a]llowing new prior art to be considered on remand after the Final Decision on the merits would essentially be starting a new IPR proceeding.” Paper 80, 9. As Patent Owner asserts, “[t]he parties and the Board would have to argue and consider new grounds, new expert testimony would have to be taken and presented, and a new Final Decision would have to be rendered.” Id. The Federal Circuit’s instruction is limited: “We remand this case to the Board so that it may consider the patentability of the surviving disputed dependent claims 4, 6-9, and 21.” MaxLinear, 880 F.3d at 1378. We have complied with this instruction in two ways: first, by applying the Federal Circuit’s instruction regarding the collateral-estoppel impact on challenged claims 1–3, 5, and 10–20; and, second, by clarifying that Petitioner’s argument regarding the combination of Van De Plassche and Ishikawa compels a conclusion that Petitioner’s showing is insufficient with respect to claims 4, 6–9, and 21, independent of any conclusion previously reached with respect to independent claims 1 and 17. While the Federal Circuit includes language in its remand order that might be construed as suggesting applying different prior art in the latter analysis, 880 F.3d at 1377, the scope of this proceeding is limited by the prior art and the arguments in the Petition here.

Patent Owner’s distinction relates to a portion of one factor (education) in a determination that involves several factors.

See Opp. 3; Ex. 2006, 154:24–155:4.

Dr. Hashemi could have answered the questions and sought a protective order that would insulate his answers from the public record, providing the Board with the information needed to perform a focused evaluation of the credibility and reliability of specific statements in his testimony. But a significant measure of responsibility for whether Dr. Hashemi’s testimony is tainted with bias lies with Patent Owner for declining to pursue the issue to a point of greater clarification. Indeed, we are limited in how strongly we can fault Petitioner for failing to submit a clarifying declaration from Dr. Hashemi, in light of Patent Owner’s decision to “withdraw” the questions at issue. Because the evidence is insufficiently developed, we are similarly limited in the degree to which we can draw adverse inferences from Dr. Hashemi’s refusal to answer questions, and unable to conclude, by a preponderance of the evidence, that Dr. Hashemi’s testimony is tainted by an undisclosed bias.

    “We agree with Petitioner (Pet. Reply 8–9), however, that an ordinarily skilled artisan would not have read Chou as narrowly as Patent Owner contends. Not only does Chou state that its fixture “may be configured to be installed into a recessed can housing having other geometries,” but also “recessed housings . . . developed with different geometries.” Ex. 1012, 3:65–4:7 (emphasis added). In light of this express teaching in Chou, we do not agree that Chou’s teachings are confined to 5- and 6-inch can lights, or even can lights in general. Junction boxes represent another geometry that can serve as a recessed housing for an LED light fixture. See Ex. 1023, 30:17–31:7 (Dr. Bretschneider testifying that, by 2009, LED light fixtures attached to junction boxes were known with “certain parts” inside the box). In addition, the fact that certain figures of Chou might depict a junction box external to a can light does not mean that junction boxes are excluded from the universe of “recessed housings” contemplated in the quotation above. In addition, Patent Owner contends Petitioner has provided no reason or motivation to combine Wegner with Chou. PO Resp. 10–11. Patent Owner also contends an ordinarily skilled artisan would not have combined Wegner with Chou because Wegner pertains to a light with a tall reflector, which must be installed in a can light fixture (and not a junction box). Id. at 11–12 (citing Ex. 2001 ¶¶ 74–75, 133–137). Yet Petitioner only cites Wegner for its teaching of removing an Edison base from an LED light fixture to facilitate direct wiring, and not for anything to do with reflectors. Pet. 24 (citing Ex. 1002 ¶ 53; Ex. 1016, 11:3–32). As such, Patent Owner’s arguments regarding Wegner’s light reflectors amounts to a bodily incorporation argument, which is not the test for obviousness. See In re Keller, 642 F.2d 413, 425 (CCPA 1981) (“The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference.”). We are persuaded that, based on Wegner, an ordinarily skilled artisan would have known to remove the Edison base of Chou’s fixture regardless of the type of reflector and housing used in Wegner’s fixture. See Ex. 1002 ¶ 53. Regarding motivation, Petitioner posits a market-based rationale, namely, that an ordinarily skilled artisan would have been motivated to make a version of Chou’s luminaire to fit nominally sized junction boxes to serve the new construction market. Pet. 25 (citing Ex. 1002 ¶ 54). Dr. Coleman testifies that the Edison base would have been removed to make Chou’s luminaire work in a junction box. Ex. 1002 ¶ 53. We are persuaded that an ordinarily skilled artisan wanting to modify Chou for use in junction boxes would have known to make this modification.” slip op. at 19

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed petitioner constructionDecided for petitioner

    “construction against the prior art than it does to construction of the term itself. Patent Owner’s proposed construction, like Petitioner’s, does not, on its face, exclude RF protocol conversion. In this respect, we agree with Petitioner that Patent Owner is improperly attempting to read in additional limitations that go beyond claim 5’s broad recitation of a “transmitter . . . configured to encode the electrical signal.” See Paper 45, 3. As Petitioner further observes, the Specification of the ’661 patent refers interchangeably to data controller 324 (shown in Figures 3A–3E, not reproduced here) as “data formatter 324” (emphasis added), which “operates to form concise data packets.” Id.; Ex. 1001, col. 8, ll. 49–51. Petitioner’s proposed construction is thus consistent with the Specification. Patent Owner agrees that data controller 324 “encodes a physical condition into a function code,” but emphasizes that it does so “before getting converted by the RF transmitter.” Paper 44, 3. The distinction Patent Owner relies on to exclude RF protocol conversion from its proposed construction would improperly narrow the scope of the claim by implicitly adding a limitation that has no express basis in the claim. In re Prater, 415 F.2d 1393, 1404–05 (CCPA 1969) (“Nevertheless, ‘reading a claim in the light of the specification,’ to thereby interpret limitations explicitly recited in the claim, is a quite different thing from ‘reading limitations of the specification into a claim,’ to thereby narrow the scope of the claim by implicitly adding disclosed limitations which have no express basis in the claim.”). Having thus considered the parties’ positions, we adopt Petitioner’s proposed construction of “encoded electrical signal” as “coded information representing the electrical signal generated by the sensor.” We address application of this construction to the prior art in the analysis below.” slip op. at 12

  • Skill levelSkill level patent owner adoptedDecided for patent owner

    “Patent Owner does not advocate for a specific level of skill in its Response, but its expert, Kevin C. Almeroth, Ph.D., articulates a level of skill similar to Petitioner’s proposal. Ex. 2009 ¶ 75. Specifically, Dr. Almeroth opines that a person of ordinary skill “would have the equivalent of a four-year degree from an accredited institution (usually denoted as a B.S. degree) in computer science, computer engineering or the equivalent and experience with, or exposure to, computer networks and routing.” Id. In addition, according to Dr. Almeroth, a person of ordinary skill “would also have approximately two years of professional experience with computer networking, routing, and wireless networks. Id. And “[a]dditional graduate education could substitute for professional experience, while significant experience in the field might substitute for formal education.” Id. Given the similarity of articulations by the respective experts, and because our Decision does not depend on nuanced distinctions of the level of skill in the art, we adopt Dr. Almeroth’s more detailed articulation, but include electrical engineering as an additional alternative educational background, as indicated by Mr. Kinney.” slip op. at 15

    “We thus agree with Patent Owner that the rationale articulated by Petitioner is conclusory, and insufficiently supported. PO Resp. 30–31. On the record before us, it is more reasonable to construe “the transceiver identification information” as referring to something other than the identification information for the at least one wireless transmitter. For example, Patent Owner contends that “[o]ne skilled in the art, reading the plain text of claims 5 and 8, would easily recognize that the ‘transceiver’ referred to in claim 8 is the transmitter in claim 5 that is configured to both send and receive signals.” Id. at 33. Patent Owner provides support for this reading both by identifying disclosure in the Specification of the ’661 patent consistent with its position, and through testimony by its expert, Dr. Almeroth. Id. at 33–36 (citing Ex. 1001, Figs. 2, 3C, 3D, col. 6, ll. 3–8, col. 9, ll. 53–56, col. 10, ll. 32–34; Ex. 2009 ¶¶ 125–132). For example, Dr. Almeroth testifies that Mason’s AMR server “at most would need only some meter identification number and a meter reading.” Ex. 2009 ¶ 134. We credit this testimony, as well as Dr. Almeroth’s assertion that “[t]ransceiver identification information is extraneous for the needs of the AMR server in Cunningham and Mason.” Id. Ultimately, we need not resolve the construction issues, and the issue of whether claim 8 is indefinite is not before us. 35 U.S.C. § 311(b) (limiting inter partes review to “a ground that could be raised under section 102 or 103”). It is sufficient for us to determine whether Petitioner has put forth sufficient evidence to meet its burden of establishing that claim 8 would have been obvious over the combination of Mason, Shuey, and Cunningham. In light of the foregoing considerations, we conclude that Petitioner has not.” slip op. at 34

    “c. “one or more additional wireless transmitters” Third, Petitioner combines the teachings of Shuey with those of Mason in addressing claim 5’s recitation of “one or more additional wireless transmitters.” Id. at 62–63. The claim requires that each such additional wireless transmitter is “electrically interfaced with a sensor and configured to receive the RF signal and retransmit the RF signal,” i.e., to act as a repeater. Ex. 1001, col. 19, ll. 22–24. As discussed above, Mason discloses that meter 12D is considered “inaccessible” with respect to node 18, and that another meter within the network may act as a repeater so that the inaccessible meter may still be contacted. Id. at col. 6, ll. 27–35. Petitioner cites Shuey for details regarding the information included in retransmission by meters acting as repeaters, and provides sufficient reason to effect the combination in light of Mason’s explicit reference to Shuey: “A POSITA would have been motivated to incorporate into Mason’s system Shuey’s teaching of a repeater that retransmits all of the claimed information, because Mason explicitly notes that Shuey’s system is a system for which Mason’s invention is particularly suited.” Pet. 58–59 (citing Ex. 1007, col. 6, ll. 35–38; Ex. 1002 ¶¶ 110–112).

    “We are not persuaded by this reasoning.

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 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.

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

    “sequence.” Petitioner’s declarant, Dr. Zhi Ding, attests that the phrase is “a well-understood term of art.” Ding Decl. ¶ 35 (citing Ex. 1016, 127–33). Consistent with Dr. Ding’s testimony, we applied a preliminary construction of “hopping sequence” in the Institution Decision as “the order in which the communications network hops among the set of frequencies.” Dec. 7. That construction is not contested by Patent Owner, and we adopt it for this Final Written Decision.” slip op. at 8

    “as disclosed by Gerten’s description of modified frequency hopping schemes. Id. at 14. 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. Id. at 18 (citing Ding Decl. ¶¶ 53– 55).” slip op. at 15

  • Obviousness (§103) › Analogous artAnalogous artDecided for petitioner

    “Two criteria have evolved for determining whether prior art is analogous: (1) whether the art is from the same field of endeavor, regardless of the problem addressed, and (2) if the reference is not within the field of the inventor’s endeavor, whether the reference still is reasonably pertinent to the particular problem with which the inventor is involved. In re Clay, 966 F.2d 656, 658–59 (Fed. Cir. 1992) (citing In re Deminski, 796 F.2d 436, 442 (Fed. Cir. 1986); In re Wood, 599 F.2d 1032, 1036 (CCPA 1979)). Patent Owner understates the degree to which Petitioner addresses the analogousness of the art by focusing on Petitioner’s contention that Gerten and Cuffaro are in the same field of endeavor. PO Resp. 40 (citing Pet. 30). Petitioner also addresses the second prong of the Clay test by providing reasons why a person of skill in the art would use the transmitted performance data of Cuffaro in the selection process of Gerten, including improved accuracy in determining the impact on the receiver unit from the interference on a given channel. See Pet. 31. We agree with Petitioner’s reasoning and find that Cuffaro and Gerten are analogous art to the claimed invention at least because they are reasonably pertinent to the particular problem with which the inventor was involved. We conclude that Petitioner has demonstrated, by a preponderance of the evidence, that claims 2, 14, and 26 are unpatentable under 35 U.S.C. § 103(a) over Gerten and Cuffaro.” slip op. at 26
