    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “Petitioner defines a person of ordinary skill in the art as having “a Master’s degree in electrical engineering, and at least two years of relevant work experience in the field of integrated circuit design and manufacturing.” Pet. 13 (citing Ex. 1003 ¶¶ 32–37, 57). Patent Owner does not dispute Petitioner’s definition. PO Resp. 6. We adopt Petitioner’s proposed definition of the level of ordinary skill in the art because it is supported by unopposed declaration testimony and appears to be consistent with the disclosures of the ’634 patent and the asserted prior art references. See Ex. 1001, 1:6–2:33 (describing the invention and related art in terms of integrated circuit design and fabrication); see also Ex. 1006 ¶¶ 1–6 (Hirler); Ex. 1008 ¶¶ 1–37 (Kobayashi); Ex. 1009 ¶¶ 2–29 (Shiraishi). Neither party, moreover, indicates the overall result would change based on a different definition.” slip op. at 7

      “Petitioner argues that “the sidewalls of said trenches in said base layer are covered” should be construed to mean that “the entire sidewalls of” those trenches are covered. Pet. 18–19. We refer to this as “the sidewall limitation.” Petitioner shows persuasively that the disclosure and file history of the ’634 patent support its position on the sidewall limitation. Id. Patent Owner, for its part, observes that, after the filing of the Petition. two District Courts adopted the construction proposed by Petitioner.” PO Resp. 21 (citing Ex. 2010, 6–9; Ex. 2011, 23). Patent Owner also agrees to apply Petitioner’s construction for purposes of this proceeding. Id. We agree with Patent Owner that an express construction of the sidewall limitation is necessary to this Decision, id., and adopt Petitioner’s undisputed definition because it is supported by the record. No other claim term requires express construction for purposes of this Decision.” slip op. at 8

      “Alternatively, even if we set aside that timing issue, Dr. Liu’s bare opinion, advanced for the first time during cross-examination, that an epitaxial layer is “obvious” from Hirler’s disclosure is inadequate to support the challenges. Id. at 24–25. We accord little weight to Dr. Liu’s opinion because it is conclusory. See Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). In any event, Petitioner does not meet, on this record, the “high standard” required to establish an inherent disclosure of an epitaxial layer in Hirler. PO Resp. 24.6 Dr. Liu opined for the first time during cross-examination “that it would have been impossible to create Hirler’s more lightly doped n- drift zone layer on top of its more heavily doped n+ substrate layer other than via epitaxy.” Id. at 25 (citing Ex. 2014, 164:16– 165:20). But Patent Owner effectively refutes that proposition with evidence that such a layer “could be created by counter-doping,” even if, as Dr. Liu contends, counter-doping may have been less ideal due to “disadvantageous mobility.” Id. (citing Ex. 2012 ¶ 133; Ex. 2014, 166:15–167:8).” slip op. at 11

    • PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Institution denied fintivDenied

      “litigation, the Board assesses all relevant circumstances, including the merits, to balance considerations such as system efficiency, fairness, and patent quality. See Fintiv, Paper 11; NHK Spring Co. v. Intri-Plex Techs., Inc., IPR2018-00752, Paper 8 at 19–20 (PTAB Sept. 12, 2018) (precedential). We consider six factors as part of this balanced assessment when determining whether to use our discretion to deny institution: 1. whether the court granted a stay or evidence exists that one may be granted if a proceeding is instituted; 2. proximity of the court’s trial date to the Board’s projected statutory deadline for a final written decision; 3. investment in the parallel proceeding by the court and the parties; 4. overlap between issues raised in the petition and in the parallel proceeding; 5. whether the petitioner and the defendant in the parallel proceeding are the same party; and 6. other circumstances that impact the Board’s exercise of discretion, including the merits. Fintiv, Paper 11 at 5–6. In evaluating these factors, we “take[] a holistic view of whether efficiency and integrity of the system are best served by denying or instituting review.” Id. at 6.” slip op. at 8

      “vibrations on a surface and using the vibrations to generate a control signal for a device. Ex. 1004 ¶¶ 21, 25, 29, 30, 36. To measure vibrations on a surface, Murakoshi’s sensor must be fixed within the housing and held in position relative to the surface. See Ex. 1003 ¶¶ 142 (“it is necessary to hold a sensor in a fixed position relative to a sensing surface to provide a fixed reference point for accurate detection of vibratory signals”), 174 (“the sensor is held in a particular position within the housing and relative to the surface that the housing is mounted to”). Stewart teaches the opposite: a sensor that is vibrated inside a housing to measure rotational movement. Ex. 1006, 5:54–56, 6:5–10, 6:20–31; Ex. 2001 ¶¶ 100, 133, 138. Thus, Stewart’s sensor is flexibly suspended with brackets inside the housing to allow movement and minimize transmission of vibrations from the surface to the sensor. Ex. 1006, 5:7–24, 7:61–64; Ex. 2001 ¶ 102. Petitioner combines Murakoshi with Stewart’s brackets and case mounts to fix the sensor to prevent it from moving within the housing and thus enable the sensor to detect vibrations from outside the housing. See Pet. 23, 31–35. But Stewart’s teachings undermine the very reason proffered by Petitioner, because Stewart’s sensor is movably suspended within the DePuy Spine, Inc. v. Medtronic Sofamor Danek, Inc., 567 F.3d 1314, 1326 (Fed. Cir. 2009) (“An inference of nonobviousness is especially strong where the prior art’s teachings undermine the very reason being proffered as to why a person of ordinary skill would have combined the known elements.”).” slip op. at 14

      “A holistic balancing of the Fintiv factors weighs in favor of discretionary denial of the Petition. As discussed above, factor 2 weighs heavily in favor of discretionary denial because the district court is likely to address patentability issues at trial before we would issue a final written decision. Factor 4 weighs in favor of discretionary denial, as does Factor 5 at least to some degree. Factors 1 and 6 are neutral. Factor 3 weighs against discretionary denial, but this factor does not outweigh the other factors under the circumstances of this case. Thus, the evidence of record favors exercising our discretion to deny institution of an inter partes review.” slip op. at 19

      “Based on the preliminary evidence, Petitioner has not shown that Vardi’s radio resource database from the server, which includes unauthenticated third-party information, teaches the claimed “authenticated access point list” transmitted by or received from the server. Petitioner has not cited to any evidence that a list including previously connected access points and unauthenticated third-party data constitutes the ordinary and customary meaning of the term “authenticated access point list.” To the extent that Petitioner is arguing that the term should be construed in a way that departs from its ordinary and customary meaning, Petitioner has not pointed to evidence for such a departure in the intrinsic record, and we are aware of no such evidence. We note that the ’522 patent states, “[b]y way of example, but not limitation,” that an “authenticated access point may include . . . an access point previously connected with [the] end device.” Ex. 1001, 4:33–36. But this does not appear to suggest that a prior connection is sufficient to authenticate the access point in the context of the ’552 patent.” slip op. at 18

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).

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

      “We preliminarily disagree with Patent Owner. Although the claim lists step 1b before step 1d, method steps are not ordinarily construed to require a specific order of performance unless the claims or Specification directly or implicitly require that specific order. See Altiris, Inc. v. Symantec Corp., 318 F.3d 1363, 1369–70 (Fed. Cir. 2003). Nothing in the express claim language precludes performing step 1d before step 1b, as in Zhang. For example, the claim does not contain temporal terms, like “then” or “next,” nor does the claim otherwise specify that step 1b must precede step 1d. Although Patent Owner points out that a term of step 1d (i.e., the one more available devices) derives antecedent basis from text in step 1b (i.e., one more available devices), this alone does not directly or implicitly require performing step 1b before step 1d. Prelim Resp. 6–7 (citing Ex. 1002, 240, ’648 patent prosecution history). Nor does the Specification require performing the step of identifying devices as available before the step of wirelessly signaling those devices or even that the steps be mutually exclusive. For example, there are no statements that this step order is important, nor disclaimer of any other order, nor any prosecution history indicating a surrender of any other order. Moreover, according to the Specification, announcer 30, which is the component that identifies devices as available prior to the wirelessly signaling, is only “preferably provided.” Ex. 1001, 7:28–31. Even assuming Patent Owner were correct that step 1b must precede step 1d, Patent Owner’s position that device(s) must be identified as available does not appear to be commensurate with the claims. According to its plain meaning, limitation 1b does not appear to require identifying devices as available; the claim merely requires identifying “available devices.” See In re Self, 671 F.2d 1344, 1348 (CCPA 1982) (rejecting arguments “not based on limitations appearing in the claims”). In other words, the claim does not appear to require identifying (i.e., determining) whether devices are available but merely requires identifying devices that happen to be available. According to our preliminary understanding, Zhang’s mobile device 1) discovers (identifies) connected available and unavailable helper servers, and then 2) sends (wirelessly signals) service requests to compatible available and unavailable helper servers. Ex. 1004, 3:44–4:8, 6:51–7:13. Thus, Zhang identifies and then wirelessly signals available devices (Zhang also identifies and then wirelessly signals unavailable devices). As such, we preliminary determine that Zhang meets the claim language “identifying one or more available devices” and “wirelessly signaling the one or more available devices.”” slip op. at 18
