      “Petitioner argues that a person of ordinary skill in the art “would have had . . . a bachelor’s degree in electrical engineering, microelectronics, or equivalent and . . . two to three years of industry or research experience in the field of wireless energy transfer,” and that “a higher level of education or skill might make up for less experience, and vice-versa.” Pet. 6 (citing Ex. 1003 ¶¶ 39–44). Patent Owner does not contest this. See PO Resp. Petitioner’s proposed articulation is supported by testimonial evidence and appears to be consistent with the types of problems and solutions in the ’654 patent. See Ex. 1001, 1:15–28.

      “We agree with Petitioner that the evidence does not suggest (and Patent Owner does not explicitly argue) that the terms “transmitting antenna” and “receiving” antenna depart from the ordinary and customary meanings of those terms. Pet. 1–2. However, for the reasons discussed below, the outcome of our decision would be the same whether we adopted Petitioner’s or Patent Owner’s proposed construction.

      “spaced configuration are not confined to ferrite cores 32 and 3, and that at least a component of the flux lines will escape the cores. See Ex. 1032 ¶¶ 48–52; Ex. 1038 ¶ 54 Fig. 2. Indeed, the evidence suggests (and Dr. Horenstein acknowledges in his first declaration) that at least a component of flux will escape the core of even a traditional transformer. See Ex. 1032 ¶¶ 45–47; Ex. 1044, 6; Ex. 2001 ¶ 27. In his second declaration, Dr. Horenstein provides contrary testimony that in Odachi’s open configuration during alignment, cores 32 and 3 “act to confine or guide the magnetic flux lines, rather than radiate them into free space,” and “the flux lines would [not] leave the gap area and enter into the space distal to the magnetic circuit.” Ex. 2010 ¶ 69. But in view of Dr. Horenstein’s contrary position in his first declaration, and the lack of supporting evidence in his second, we do not find it credible. 37 C.F.R. § 42.65(a) (2022) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); Apple Inc. v.

      “(4) Analysis We are persuaded by Petitioner’s argument that during the alignment process in Odachi corresponding to claim 13, there is a “spaced distance between the primary inductive coupler [230] and the secondary inductive receptacle 2” which is “reduced gradually and electromagnetic induction occurs between the coupler to the receptacle when the former coupler comes close to the latter receptacle.” Ex. 1005, 6:1–6. Thus, prior to any contact or precise alignment between the two cores, “an electromotive force is induced in the secondary coil 4 and this induced force is increased with the decrease in the spaced distance.” Id. at 6:6–8. At least in that spaced configuration, the evidence of record suggests that primary coil 31 produces a near-field component of flux into free space (the air space between the coils where there is no intervening core material) that is intercepted by secondary coil 4 to effect resonant inductive coupling, and that secondary coil 4 intercepts and receives the near-field component of flux in free space that is generated by primary coil 31 to effect resonant inductive coupling. See Ex. 1032 ¶¶ 48–52, 55. Thus, we find that Odachi discloses a “transmitting antenna” (coil 31) and a “receiving antenna” (coil 4) under Patent Owner’s proposed construction. We would reach the same finding under Petitioner’s proposed broader construction because the evidence suggests that Odachi’s coils 31 and 4 would have been considered “antennas” under the parties’ uncontested definition of that term, which is “a device that radiates and/or receives radio waves.” See id. ¶¶ 43–47, 53–54; Ex. 1032 ¶ 15 (Dr. Allen agreeing with this definition of “antenna”); Ex. 2001 ¶ 25 (Dr. Horenstein agreeing with this definition of “antenna”)). In addition, Petitioner persuasively shows that the free space between Odachi’s coils in the spaced configuration includes the “near-field region,” which includes the induction field around primary coil 31. See Ex. 2006, 498; Ex. 1045, 5:4–7; Ex. 1032 ¶¶ 53–54). Dr. Horenstein’s testimony does not contradict this. Although he points out that there are separate terms for inductive, near, and far fields, he also acknowledges that “[t]he region of space closer to the antenna than the far field is the near-field region.” Ex. 2010 ¶ 37 (citing Ex. 2006, 275).8” slip op. at 22

      “Thus, although Petitioner contends that Njølstad implements a dynamically changeable frequency for each domain wherein a local “rate requirement can dynamically be configured” such that “the locally generated clock rate is just high enough to perform the actual processing task” at that rate (Pet. 31 (citing Ex. 1009 § IV.D)), such teaching merely supports Petitioner’s contention that the frequency is dynamically changeable at the local level (id.). However, as Patent Owner points out, such showing is not a compelling disclosure of the frequency generation being independent of the frequencies of the other domains, as required by the challenged claims. Prelim. Resp. 28–34. For the foregoing reasons, we conclude that Petitioner has not presented compelling merits that Njølstad teaches “the frequency being dynamically changeable independently of the frequencies of the clock signals generated for others of the plurality of domains” as recited in claim 1 and similarly recited in claim 8.” slip op. at 25

      “Having considered all the evidence of record relating to Mr. Taniguchi’s activities during the relevant time frame, we find that Patent Owner has not produced sufficient corroborating evidence to show that Mr. Taniguchi’s work on reducing to practice the claimed invention was reasonably continuous during the critical period between September 19, 2008 (the filing date of Ueda), and November 18, 2008 (the filing date of the Japanese patent application). Although there is corroborating evidence of diligence beginning on November 6, 2008, when Mr. Taniguchi transmitted a draft application to the Baba law firm, there is no evidence of any diligence prior to that date, other than Mr. Taniguchi’s own testimony. We do not agree with Patent Owner that the evidence of Mr. Taniguchi’s other activities for NEC, or research relating to IPTV, corroborate Mr. Taniguchi’s reduction to practice of the claimed invention. Although these activities may have something to do with the general subject matter of IPTV, Patent Owner has not shown any nexus between these activities and the challenged claims. See Naber, 567 F.2d at 385 (“It is well settled that, to satisfy the ‘reasonable diligence’ requirement . . . , the work relied on must ordinarily be directly related to reduction to practice of the invention . . . in issue.” (citing cases)). Although Mr. Taniguchi doubtlessly spent substantial time preparing the application he completed on November 6, 2008 (see Ex. 2017), there is no corroborating evidence that this work was reasonably continuous during the critical period. As far as the corroborating evidence attests, Mr. Taniguchi could have done no work on the draft until early November, or he could have worked on the draft briefly in August and put it aside until early November. Considering all the evidence as to Mr. Taniguchi’s activities, we find that Patent Owner has not met its burden of producing corroborating evidence that the named inventors of the ’427 patent exercised reasonably continuous diligence during the critical period when Ueda was filed until the constructive reduction to practice that occurred on November 18, 2008.

      “In general, we disagree with Patent Owner that, in showing a reason to incorporate the SIP Standard’s teachings about proxy servers, Petitioner must necessarily show that Ueda’s system was deficient or inferior. A patent challenger “does not need to show that there was a known problem with the prior art system in order to articulate the required rational underpinning for the proposed combination.” Unwired Planet, LLC v. Google Inc., 841 F.3d 995, 1002–03 (Fed. Cir. 2016). Also, “when a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result.” KSR, 550 U.S. at 416. For this reason and the specific reasons discussed below, we find Patent Owner’s arguments unpersuasive. The evidence of record suggests that it would have been within the ordinary skill in the art to modify Ueda’s system by replacing direct communication between content-providing device 150 and servers 191 or 192 with an indirect connection in the form of proxy servers using well-known, predictable techniques as described in the SIP Standard.” slip op. at 33

    • Novelty / Anticipation (§102) › Priority / effective filing date / continuation supportReference is prior artPriority date, deniedDecided for petitioner

      “Taniguchi’s activities during the relevant time frame, we find that Patent Owner has not produced sufficient corroborating evidence to show that Mr. Taniguchi’s work on reducing to practice the claimed invention was reasonably continuous during the critical period between September 19, 2008 (the filing date of Ueda), and November 18, 2008 (the filing date of the Japanese patent application). Although there is corroborating evidence of diligence beginning on November 6, 2008, when Mr. Taniguchi transmitted a draft application to the Baba law firm, there is no evidence of any diligence prior to that date, other than Mr. Taniguchi’s own testimony. We do not agree with Patent Owner that the evidence of Mr. Taniguchi’s other activities for NEC, or research relating to IPTV, corroborate Mr. Taniguchi’s reduction to practice of the claimed invention. Although these activities may have something to do with the general subject matter of IPTV, Patent Owner has not shown any nexus between these activities and the challenged claims. See Naber v. Cricchi, 567 F.2d at 385 (“It is well settled that, to satisfy the ‘reasonable diligence’ requirement . . . , the work relied on must ordinarily be directly related to reduction to practice of the invention . . . in issue.” (citing cases)). Although Mr. Taniguchi doubtlessly spent substantial time preparing the application he completed on November 6, 2008 (see Ex. 2017), there is no corroborating evidence that this work was reasonably continuous during the critical period. As far as the corroborating evidence attests, Mr. Taniguchi could have done no work on the draft until early November, or he could have worked on the draft briefly in August and put it aside until early November. Considering all the evidence as to Mr. Taniguchi’s activities, we find that Patent Owner has not met its burden of producing corroborating evidence that the named inventors of the ’427 patent exercised reasonably continuous diligence during the critical period when Ueda was filed until the” slip op. at 23

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

      “In general, we disagree with Patent Owner that, in showing a reason to incorporate the SIP Standard’s teachings about proxy servers, Petitioner must necessarily show that Ueda’s system was deficient or inferior. A patent challenger “does not need to show that there was a known problem with the prior art system in order to articulate the required rational underpinning for the proposed combination.” Unwired Planet, LLC v. Google Inc., 841 F.3d 995, 1002–03 (Fed. Cir. 2016). Also, “when a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result.” KSR, 550 U.S. at 416. For this reason and the specific reasons discussed below, we find Patent Owner’s arguments unpersuasive. The evidence of record suggests that it would have been within the ordinary skill in the art to modify Ueda’s system by replacing direct communication between content-providing device 150 and servers 191 or 192 with an indirect connection in the form of proxy servers using well-known, predictable techniques as described in the SIP Standard.” slip op. at 32

      “(4) Whether Ueda Teaches Away from Providing Play-list Information While Establishing a Connection Finally, Patent Owner argues that Ueda teaches away from providing “play-list information” at the same time as establishing a connection, because Ueda teaches successfully completing user authentication before transmitting the playlist. PO Resp. 52–53 (citing Ex. 1003 ¶¶ 56, 365, Fig. 25; Ex. 2001 ¶ 99). According to Patent Owner, “Petitioner’s argument fails to reconcile[] this ordering of Ueda, which would prevent implementation of the proposed combination with the SDP Standard, in which the playlist is transmitted as part of the ‘Session Initiation.’” Id. at 53 (citing Ex. 2001 ¶ 100). In its Reply, Petitioner argues that limitation 1g “does not require transmitting ‘play-list information’ ‘at the same time’ as authentication, but at a same time ‘the one or more connection control servers executes a process for guaranteeing a communication bandwidth . . . as a process for establishing the connection.’” Pet. Reply 23. Petitioner also argues that the ’427 patent also describes an authentication step before transmitting the play-list information. Id. (citing Ex. 1001, 12:56–13:13, 13:50–58, Fig. 4). We find Petitioner’s arguments persuasive, and we disagree with Patent Owner that claim 1 restricts the timing of user authentication. As Petitioner notes, user authentication occurs in the ’427 patent before the process of establishing a connection as depicted in Figure 5. See Ex. 1001, 12:36–55, Fig. 4 (user authentication occurs when user equipment 2 is powered-up); id. at 13:50–58 (SIP message A501, at the beginning of Figure 5, includes “user authentication success information”). But we find nothing in the claim language, itself, that requires any particular timing for authentication. Nor do we understand Petitioner’s motivation-to-combine argument to hinge on the timing of authentication. Thus, Ueda does not “criticize, discredit, or otherwise discourage” the claimed invention. In re Fulton, 391 F.3d 1195, 1201 (Fed. Cir. 2004).” slip op. at 58

    • Obviousness (§103) › Motivation to combine / reasonable expectation of success › HindsightDecided for petitioner

      “We find Petitioner’s arguments persuasive. Petitioner does not rely solely on the SDP Standard for teaching the sending of play-list information, but also relies on Ueda, which discloses sending a playlist including an identification of main content, commercial content, and an output sequence, as we discuss in more detail below in the context of limitation 1h. See infra Section III.D.3(g). Petitioner relies on the SIP and SDP Standards for teaching that Ueda’s playlist, as with other data describing a session, may be formatted and transmitted as payload within a standard SIP message, for example using SDP fields. Based on the evidence of record, we find it persuasive that a person of ordinary skill in the art would have recognized SDP as a known way to format play-list information, since SDP has specific fields to convey the features of a playlist such as metadata and links to the content. See Pet. 50–52. Petitioner’s arguments are not based on improper hindsight bias. Although Petitioner argues that the SDP Standard “can” or “could” be used to format Ueda’s playlist, the evidence suggests that doing so would merely be “[t]he combination of familiar elements according to known methods,” and that kind of combination “is likely to be obvious when it does no more than yield predictable results.” KSR, 550 U.S. at 416. The evidence shows that is the case here. As such, the Petition relies on the predictable combination of the prior art according to known methods and on various motivations to combine the references (see Supra Sections III.D.1–2), not on the ’427 patent itself, for teaching the combination.” slip op. at 57

      “Relying on the testimony of Dr. Hansen, AT&T argues the following: [a]s of the earliest claimed priority date, a person of ordinary skill in the art at the time of the alleged invention of the ’489 patent . . . would have had a [Bachelor of Science] in Electrical Engineering or a related field with at least three years of experience designing, developing, and/or testing telecommunication systems. A [person of ordinary skill in the art] would also have familiarity with the wireless standards and well-known protocols for accessing wireless networks. More education may supplement practical experience or vice versa. Pet. 14 (citing Ex. 1002 ¶ 368). In the Preliminary Response, Innovative Sonic does not address AT&T’s assessment of the level of skill in the art. See Prelim. Resp. For purposes of this Decision, we adopt AT&T’s uncontested assessment of the level of skill in the art because it is consistent with the ’489 patent and the asserted prior art.” slip op. at 13

      “issue fares no better. With one exception, Dr. Hansen, relies on the same disclosures of the Update for 3GPP TS 36.331 v.9.4.0 to support his testimony, which, as we explain above, does not account for the plain language of the disputed limitation. Compare Pet. 26–27, 43, with Ex. 1002 ¶¶ 87–90. In addition, Dr. Hansen testifies that a person of ordinary skill in the art would have understood that “the E-UTRAN configuring the UE with one or more SCells would necessarily include the configuring of at least one SCell by a source eNB to a UE.” Ex. 1002 ¶ 91 (emphasis added). But neither AT&T nor Dr. Hansen establish inherency in its obviousness analysis. See PAR Pharm., Inc. v TWI Pharms., Inc., 773 F.3d 1186, 1194– 95 (Fed Cir. 2014) (recognizing that “inherency may supply a missing claim limitation in an obviousness analysis,” but limiting the doctrine of inherency “only when the limitation at issue is the ‘natural result’ of the combination of prior art elements” (quoting In re Oelrich, 666 F.2d 578, 581 (C.C.P.A. 1981)). Apart from the conclusory assertion above, Dr. Hansen does not identify sufficient evidentiary support demonstrating that the requirement identically recited in each of independent claims 1 and 12 of “configuring at least one SCell by a source eNB to a User Equipment (UE)” would have been the “natural result” flowing from the Update for 3GPP TS 36.331 v.9.4.0’s disclosure of the E-UTRAN configuring the UE with at least one SCell. PAR Pharm., 773 F.3d at 1195. Accordingly, we do not credit Dr. Hansen’s testimony that implicates the doctrine of inherency because it not supported by evidence of record.” slip op. at 17

      “In the Petition, AT&T contends that “the Board does not need to expressly construe any [claim] terms to resolve the arguments presented herein” because the asserted prior art “discloses all limitations under any plausible construction.” Pet. 14 (citing Ex. 1002 (Declaration of Dr. Christopher Hansen) ¶ 456). In the Preliminary Response, Innovative Sonic “agrees with [AT&T] that no [claim] term needs to be construed.” Prelim. Resp. 4 (citing Pet. 14). For purposes of this Decision, there is no readily discernible controversy between the parties that requires us to construe any claim terms at this time. See Nidec Motor Corp. v.

      “In addition to the above information, it would be beneficial for the macro eNB to send a measurement gap configuration (as dis-cussed in 3GPP TS 36.331 V1.1.2.0) allocated for the UE to the Small cell eNB so that the Small cell eNB could take measure-ment gaps into consideration when scheduling resources to the UE. For example, the small cell eNB could avoid scheduling the UE during measurement gaps because the UE cannot transmit or receive any signal to/from the Small cell during the measurement gaps. Ex. 1001, 6:41–49 (emphasis added). We particularly note the literal written description support (in italics) in the ’559 Patent that mirrors the claim [1e] language: “so that the Small cell eNB could take measurement gaps into consideration when scheduling resources to the UE.” Id. at 6:45–46 (emphasis added).

      “At this juncture, we preliminarily agree with Patent Owner’s proffered claim construction. In particular, we agree with Patent Owner’s argument that the insulating barriers would be unable to be configured to “block[] substantially all through-air arcing paths between the first and second electrical contacts,” as claimed, unless they were electrically insulating. See Ex. 1001, 4:36–44. Moreover, as Patent Owner avers, our interpretation of “insulating” as it applies to the first and second insulating barriers should be the same as for the first and second housings. See Digital Biometrics, 149 F.3d at 1345 (“whatever interpretation we assign [to a word used in a claim] should encompass both uses because the same word appearing in the same claim should be interpreted consistently” (citation omitted)). Although “a patent’s written description can set forth more than one definition of a claim term,” we do not discern that to be the case here. See Pitney Bowes, 182 F.3d at 1310. The portions of the Specification of the ’017 patent that Patent Owner cites use “insulating” and its associated tenses to mean suppressing electrical arcing and protecting from electrical burns, i.e., electrically insulating.
