      “The level of ordinary skill in the art usually is evidenced by the references themselves. See 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). Patent Owner’s definition of a person of ordinary skill in the art is similar to Petitioner’s definition with some variation in the amount of education and specificity as to the experience required. As Petitioner’s description of a person of ordinary skill appears commensurate with the subject matter before us, we apply Petitioner’s definition for purposes of this Decision. We note, however, that our determination in this proceeding would be the same under either formulation.” slip op. at 9

      “feature of scanning a wireless communication network by the mobile device receiving the streaming data for re-routing, to identify devices connected to the wireless network, are identified as capable to handle the routed media content.” Prelim. Resp. 5–6 (emphasis added) (citing Ex. 1002, 237–238). Thus, we understand the recited language to require scanning to find devices that have been identified as compatible, not just scanning to find devices and later determining which of those devices, if any, are compatible. Zhang, on the other hand, scans to find devices in the network, but that scan does not seek out devices identified as compatible. Specifically, Zhang scans to find its “helper environment” which is composed of “devices around them.” Ex. 1004, code (57); see also id. 2:16–20. The first step of Zhang’s process is to find “a local device [that] offers helper service.” Id. at 3:62–63. In the next step, Zhang then interrogates the device it scanned for in order to find out whether that device offers the necessary service. Id. at 3:63–4:5. In other words, Zhang is not scanning for compatible devices, but rather it is scanning for any device around it and then asking whether the device provides the necessary service. We find this to be insufficient because the claim is not merely seeking to identify a compatible device, but rather it is scanning “to identify a plurality of devices, identified as compatible to handle said media content.” Thus, for these claims it is not enough that the network be scanned for devices; instead, the network must be scanned for devices “identified as compatible.” The inclusion of Rofheart does not address this issue. Rofheart is relied upon to teach “that a local device identifies and connects with a plurality of remote devices.” Pet. 29. According to Petitioner, one of ordinary skill in the art would have used Rofheart’s teaching to improve Zhang by adding “the benefit of providing users control to select one or more of a plurality of devices, rather than always connecting to the first identified available compatible device, as taught by Zhang.” Id. As such, neither of the cited references addresses the recited scanning for devices identified as compatible.” slip op. at 21

Patent Owner provides a construction of the phrase “to derive, based on a beam reference signal of the network beam, a UE beam,” which Patent Owner contends is not necessary to substantiate its arguments, but is offered to “elucidate[] the distinction between the ’868 Patent and the alleged prior art from the reasons” offered by Patent Owner in its Preliminary Response. PO Resp. 8. In particular, Patent Owner contends that the above-noted phrase means “selecting a UE beam from a plurality of candidate UE beams based on a beam reference signal of the network beam.” Id. Patent Owner explains the basis for its proposed construction of the relevant phrase through citation to content of the ’868 patent including Figures 21 and 22 of the patent along with description of those Figures.

    • PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Denied

      “In Fintiv, the Board explained that “cases addressing earlier trial dates as a basis for denial under NHK Spring have sought to balance considerations such as system efficiency, fairness, and patent quality.” Fintiv, Paper 11 at 5. Fintiv sets forth six non-exclusive factors for determining “whether efficiency, fairness, and the merits support the exercise of authority to deny institution in view of an earlier trial date in the parallel proceeding.” Id. at 6. These factors consider the following: 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. Id. at 5–6. In evaluating these factors, “the Board takes 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

      “2. Claim Construction In interpreting the claims of the ’402 patent, we “us[e] the same claim construction standard that would be used to construe the claim[s] in a civil action under 35 U.S.C. [§] 282(b).” See 37 C.F.R. § 42.100(b) (2020). The claim construction standard includes construing claims in accordance with the ordinary and customary meaning of such claims as would have been understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. See id.; Phillips v. AWH Corp., 415 F.3d 1303, 1312–14 (Fed. Cir. 2005) (en banc). The parties each contend that resolution of this proceeding does not require that the meaning of any claim term be made explicit. See Pet. 15; Prelim. Resp. 8. We agree. See Realtime Data, LLC v.

      “outset, we note that the language of claims 1 and 12 is clear in reciting the presence of two distinct signals, i.e., a control signal and a reference signal, and that it is the control signal that “triggers” transmission of the reference signal. See Ex. 1001, 14:5–6, 60–62. Patent Owner credibly argues that the “two-step embodiment” of Figure 10 of the ’402 patent, and in particular steps 1005 and 1010, describe the control and reference signal transmissions that are encompassed by claims 1 and 12. See Prelim. Resp 8–10. Patent Owner also credibly argues that the Figure 10 embodiment is distinct from other disclosed embodiments, including the “single-step embodiment” of Figure 8. See id. at 10–11. Patent Owner further explains reasonably that the content of column 6 of the ’402 patent on which Petitioner relies has a more “natural reading” in distinguishing between separate transmission of a “control signal” that “triggers” separate transmission of a “reference signal” as described in connection with Figure 10 as juxtaposed with transmission of a “control channel,” which is distinct from a control signal, and a “reference signal” that may constitute a single transmission, as is described in conjunction with Figure 8. See id. at 16–17. It logically follows that if, as Patent Owner credibly argues, the claims of the ’402 patent do encompass the latter transmission scheme, rather than the former, then Petitioner’s reliance on Moon, as presented in its Petition, is insufficient to account for those claims. On this record, we need not decide whether Petitioner would likely prevail on the above-noted issues as Patent Owner raises sufficiently substantial arguments that the preliminary evidence, if unrebutted in trial, does not plainly lead to a conclusion that claim 1 is unpatentable by a preponderance of the evidence. Because, as noted above, Patent Owner has identified potentially dispositive gaps or flaws in Petitioner’s apprehension as to what is adequate in Moon’s disclosure to account for the claims of the ’402 patent, Petitioner’s proposed grounds cannot be said to rise to the level of a “compelling” meritorious challenge.” slip op. at 22

      “Although Petitioner doesn’t promote it in its Petition, we agree with Petitioner’s undisputed contention that the ordinary and customary meaning of the “announcer device” limitation is that the “streaming device is receiving rerouted data from surrounding media handling devices, rather than rerouting data to surrounding media handling devices.” Pet. 19–20. This is in accord with the specification of the ’866 patent which states that “[t]he announcer device 30 is responsible for announcing to the environment the availability of a current device for accepting routed media.” Ex. 1038, 7:22– 24 (emphasis added). The construction that Petitioner does promote, based on its interpretation of Patent Owner’s arguments in the parallel litigation, departs from the term’s ordinary meaning, yet Petitioner has presented no 7 Petitioner also argues that we should construe the term media transformer as a means-plus-function limitation invoking 35 U.S.C. § 112(f).

For example, Petitioner has not shown that the patent applicant has plainly acted as lexicographer for the term, or has plainly disavowed the full scope of the term. See Thorner v. Sony, 669 F.3d at 1365; Multiform Desiccants v. Medzam, 133 F.3d at 1477. We are aware of no evidentiary basis for Petitioner’s proposed construction in the specification or prosecution history of the ’866 patent. To the extent, if any, that Patent Owner may have argued in the parallel district court proceeding for a departure from the term’s ordinary meaning, we find no clear disavowal of the term’s scope, particularly in light of Patent Owner’s ultimate argument that the term should have its “[p]lain meaning.” Ex. 2008, 2.” slip op. at 12

      “In light of our disagreement with Petitioner’s proposed claim- construction, we do not find persuasive Petitioner’s argument that Chihara teaches the “announcer limitation,” either alone or in light of BluetoothSpec. Although Petitioner shows that Chihara’s phone 11B announces its availability for pairing with nearby Bluetooth-compatible devices, Petitioner does not argue that phone 11B indicates availability to receive any rerouted data from either headset 13 or watch 12B. To the extent that phone 11B receives streaming or media data for rerouting, it appears to receive it from a mobile or fixed communication network, not from any surrounding Bluetooth devices. See, e.g., Ex. 1004 ¶¶ 79 (phone 11B receives video and audio data via “a fixed telephone network or another mobile telephone set accommodated in a mobile communication network,” and transmits that streaming data to watch 12B and headset 13), 53–54 (calls arrive via mobile telephone antenna 26, which are then processed and transmitted via Bluetooth antenna 21 to watch 12). Regarding the bidirectional communication between phone 11B and headset 13 or watch 12B, Petitioner has not pointed to any evidence that the data sent from watch 12B or headset 13 to phone 11B includes rerouted streaming data. Similarly, Petitioner’s contention that Chihara’s phone 11B, in light of BluetoothSpec, indicates its availability (e.g., that the phone is “powered on” and transmits signals to discover nearby devices) fails to meet the plain language of claim 22, which requires the streaming device (phone 11B) to indicate its availability to receive streaming data rerouted from the surrounding devices (headset 13 or watch 12B). Thus, we determine that Petitioner has failed to show that Chihara, in view of BluetoothSpec and the other references, teaches the “announcer device” limitation. Therefore, Petitioner has not shown that it would be likely to prevail if we instituted an inter partes review.” slip op. at 17

Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91. For example, as discussed in more detail below with respect to the Uemura grounds, when fast charging using constant current is used and the charging rate is not slow, the applied voltage will be higher than the battery voltage when the constant current charging phase is stopped.

      “Petitioner contends that a person of ordinary skill in the art “would have had a Master’s degree in material science, chemical engineering, chemistry, or similar field with four years of experience designing testing, and building secondary lithium batteries.” Pet. 11 (citing Ex. 1002 ¶ 51). Petitioner further contends that a person of ordinary skill in the art would have been aware of “(1) positive electrode materials, (2) negative electrode materials, (3) separators, (4) electrolytes, (5) charge-discharge parameters, and (6) protection circuits, as well as ‘battery failure modes’ such as plating and the formation of dendrites.” Id. (citing Ex. 1002 ¶¶ 50–51). Patent Owner “does not dispute Petitioner’s level of ordinary skill.” PO Resp. 17. Upon review of the prior art of record and the parties’ arguments, we adopt Petitioner’s unopposed definition of the person of ordinary skill in the art as it is consistent with the disclosures of the ’641 patent and the prior art of record.” slip op. at 9

      “constructions. First, we agree with Petitioner that the ’641 patent indicates that the charge cut-off voltage selected for a particular battery need not be a fixed property of the battery or something that is set by the design and chemistry of the battery. Consistent with this conclusion, the ’641 patent discloses that a “charging device controls the charge cut-off voltage of the single lithium-ion cell within a range from 4.3 V to 5.8 V.” Ex. 1001, 9:50– 55. This strongly suggests that the charge cut-off voltage is controlled by the charger and is not necessarily an inherent property of the battery. Patent Owner contends that this is merely an unclaimed embodiment, but the relevant disclosure states that the charging device for the “present invention” may be any type of device “with the proviso that said charging device controls the charge cut-off voltage.” Id. at 9:50–53.” slip op. at 12

Ex. 1001, 16:56–61, 17:6–11. Although the parties dispute the precise scope of these claim terms, the parties agree that the first use of “charge cut-off voltage” in claims 1 and 5 refers to the potential of the battery as a whole (between the cathode and the anode), and not a half-cell voltage using lithium metal as a counter electrode.10 Tr. 17:1–3 (agreeing 10 With respect to the phrase “as calculated by a theoretic capacity with a charge cut-off voltage set at 4.2 V,” the parties in fact appear to be in that the first use of “charge cut-off voltage” in claim 5 refers to a full-cell voltage); Sur-reply 5; PO Resp. 22.

Pet. Reply 11–12 (citing Ex. 1009 ¶ 81; Ex. 1044 ¶¶ 56–59). This argument is not persuasive because Mr. Juzkow unambiguously testified that charging in Uemura stopped when the applied voltage reached 4.3 V, and Uemura discloses that the battery was charged “at” a voltage ranging from 4.3 V to 2.0 V, not “to” such a voltage.
