      “Relying on the declaration testimony of Dr. Kotzin, Petitioner contends that an ordinarily skilled artisan for the ’889 patent [w]ould have been someone knowledgeable and familiar with the wireless communications systems that are pertinent to the ’889 patent. That person would have a bachelor’s degree in electrical engineering, computer engineering, computer science, or equivalent training, and approximately two years of experience working in the field of wireless communication systems or design of similar communication systems. Pet. 18–19 (citing Ex. 1003 ¶ 25). Patent Owner does not dispute Petitioner’s contention as to the level of ordinary skill in the art. See generally, Prelim. Resp. Based on this record, and because there is no dispute, we adopt Petitioner’s articulation of the level of ordinary skill in the art, which is consistent with the ’889 patent and the asserted prior art.

      “We point out that in contrast with Patent Owner’s case law, the “indefinite article ‘a’ or ‘an’ in patent parlance usually carries the meaning of ‘one or more’ in open-ended claims containing the transitional phrase ‘comprising.’” KCJ Corp. v. Kinetic Concepts, Inc., 223 F.3d 1351, 1356 (Fed.

      “Second, Petitioner demonstrates that the combination of Kalliola and Vauclair teaches claim limitations 1(d)(iv) and 1(d)(v). As discussed and cited to above, the Petition identifies that, with Kalliola’s touch screen as the claimed “touch screen,” Kalliola’s processor presents a graphical user interface via its touch screen as set forth for limitation 1(c) and 1(d)(ii), and Kalliola’s processor operates in conjunction with its graphical user interface to perform claimed steps as set forth for limitation 1(d)(iii). See Pet. 20–29. We agree that the assertions are supported by Kalliola’s disclosure of a touch screen with a graphical user interface presented thereon, where “tactile elements” “allow the user . . . to enter data . . . into the device.” See Ex. 1004 ¶¶ 26, 40, 42, 44, 51, 71, Figs. 3, 5. Petitioner also asserts, and we agree, that Kalliola teaches the use of Bluetooth-enabled emitters in remote devices that communicate with its wireless communication device with a signal emitter. Pet. 29–31 (citing Ex. 104 ¶¶ 9, 71, 73–75, 77, 107, Fig. 5). Petitioner contends, and we agree, that Vauclair provides additional specificity regarding the pairing process between two devices with its disclosures of a pairing process between devices using protocols that include Bluetooth, wherein a user can select a pairing option from a menu on a display. Id. at 31–32 (citing Ex. 1005 ¶¶ 22, 24, 28, 30, 34–36, 49, Fig. 1; Ex. 1003 ¶¶ 164–167). Petitioner argues, and we agree, that it would have been obvious to a person of ordinary skill in the art to configure Kalliola to use its processor to present “a pairing menu to enable a user to initiate a Bluetooth pairing process between the WCD and the signal emitter by selecting a pairing option via the WCD’s touchscreen,” with Vauclair teaching at least the selection of a pairing option presented on its display, because the presented pairing menu on Kalliola’s touch screen would allow the user to pair the WCD with the user’s personal item signal emitters and would also allow the devices to recognize each other on subsequent connections. Id. at 34–35 (citing Ex. 1003 ¶ 172); see also Ex. 1005 ¶¶ 30, 36. Consequently, we also agree with Petitioner’s assertion that it would have been obvious to a person of skill of ordinary skill in the art that Kalliola’s graphical user interface on its touch screen would have generated signals corresponding to the user’s inputs at least to carry out designated functions, like the initiation of a pairing process, and “the signals generated by the GUI from interaction at the touchscreen would be sent to the WCD’s processor so that the processor can interpret the user’s inputs and take the appropriate action.” Pet. 35; see also Pet. Reply 2–7. Petitioner also asserts, and we agree, that generating processor signals in response to a user indication was a known mechanism for wireless devices, as were Bluetooth pairing and corresponding pairing menus, and there would be no change to the respective functions of Kalliola’s’ wireless communication devices and Vauclair’s pairing menu. Pet. 36 (citing Ex. 1003 ¶ 175). The Petition argues, and we agree, that because Bluetooth pairing and pairing menus were conventional prior to time of the invention, there would have been a reasonable expectation of success configuring Kalliola’s wireless communication device. Id. (citing Ex. 1003 ¶ 176); see also Ex. 1003 ¶¶ 71–75 (Dr. Buehrer providing evidence on Bluetooth-connected devices and associated pairing). Accordingly, we determine that Petitioner has provided sufficient evidence of rationale to combine Kalliola and Vauclair, a reasonable likelihood of success in the combination, and that the prior art teaches limitation 1(d)(iv). As to limitation 1(d)(v), we also agree with Petitioner that in response to a generation of a pairing signal as discussed in limitation 1(d)(iv), Vauclair discloses that wireless transceivers communicate a series of RF signals back and forth to pair the devices. Pet. 37–38. Petitioner asserts, and we agree, that, in combination, it would have been obvious to configure Kalliola’s Bluetooth transceiver with Vauclair’s teachings for the communication of RF signals to pair devices. Id. at 39. Petitioner contends, and we agree, that a person of ordinary skill in the art would have understood that Kalliola teaches that its wireless communication device performs Bluetooth communications with signal emitters, with the user selecting a desired signal emitter for locating objects, and that this pairing would also allow two Bluetooth devices to recognize each other on subsequent connections. Id. (Ex. 1003 ¶ 184). Petitioner asserts, and we agree, that applying Vauclair’s known technique of communicating RF signals to pair devices would improve Kalliola’s wireless communication device and yield the predictable result of Bluetooth-paired devices. Id. We also agree with Petitioner’s argument that this pairing was an understood and conventional feature of Bluetooth mobile communication devices, so there was a reasonable expectation of success in the combination. Id. at 40 (citing Ex. 1003 ¶ 186); see also Ex. 1003 ¶¶ 71–72 (Dr. Buehrer providing evidence on Bluetooth-connected devices). Accordingly, we find that Petitioner has provided sufficient evidence of rationale to combine Kalliola and Vauclair, reasonable likelihood of success in the combination, and that the prior art teaches limitation 1(d)(v).” slip op. at 40

      “Ex. 1003 ¶ 172. The Petition also asserts that, in the combination, there would be no change to the respective functions of either Kalliola’s WCD or Vauclair’s pairing menu. Pet. 36. Thus, the Petition relies on Kalliola’s processor, and its touchscreen, and graphical user interface with Vauclair’s teachings for the pairing menu displayed, wherein pairing signals are generated by Kalliola’s graphical user interface by interaction with the screen. As we discuss further below, Petitioner includes assertions that Vauclair itself teaches that the pairing signal is generated by its graphical user interface. See id. at 33, 37. The Petition, however, also relies on the combination of Kalliola and Vauclair to teach generating a pairing signal by Kalliola’s graphical user interface by interaction with its screen, as discussed above. Id. at 35. Accordingly, it is not necessary to reach the issue of whether Vauclair alone teaches that its graphical user interface generates the pairing signal. Additionally, we do not find that Petitioner’s further arguments in its Reply concerning interaction with Kalliola’s wireless communication device through its graphical user interface were impermissibly presented in view of the Petition’s specific assertions on the teachings of the combination of Kalliola and Vauclair, as discussed above, and its reliance on user interaction with Kalliola’s graphical user interface for the teaching of generating the pairing signal.

      “device.” This term appears twice in claim 11, once in the phrase “an orientation sensor to detect rotation of the mobile communication device,” and once in the phrase “rotation of the mobile communication device detected by the orientation sensor.” Ex. 1001, 39:13–14, 39:36–38. Patent Owner argues that we should construe this term as limited to “detecting the rotation of the mobile communication device as a whole, not the movement of individual components.” PO Resp. 15–18. Petitioner disputes this, arguing that “rotation of the mobile communication device” should be construed not only to cover rotation of the device as a whole but also should “encompass[] any rotation of the mobile communication device relative to any object, including itself,” which would extend to rotation of “any component of the device.” Reply 4–5. We need not resolve this dispute to determine the outcome of Petitioner’s asserted challenges to the ’246 patent. As discussed more fully below, under either party’s proposed construction of “rotation of the mobile communication device,” Petitioner has shown by a preponderance of the evidence that the challenged claims are unpatentable. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

      “On the record developed during trial, we are persuaded that Petitioner has shown by a preponderance of the evidence that Kalliola teaches “an orientation sensor to detect rotation of the mobile communication device,” where “rotation of the mobile communication device” includes rotation of the device as a whole, regardless of whether it also includes rotation of one portion of the device relative to another. Kalliola teaches “motion sensors integrated in WCD 100” that are “used to detect when WCD 100 is being moved,” as well as to detect “when user 110 moves WCD 100 too quickly for an accurate DoA estimation.” Ex. 1004 ¶¶ 84, 86. Although Patent Owner argues that Kalliola’s motion sensors do not detect rotation of the device, this is incorrect on the record as developed at trial. Kalliola teaches that the motion sensor may take “the form of a semiconductor gyroscope chip.” Id. ¶ 84. There is ample evidence that gyroscopes detect rotation. Ex. 1013, 38 (identifying as an “orientation sensor” a “[t]hree-axis gyro” and a “[d]ynamic [h]igh [r]ange [gyro]”); Ex. 1046, 49:18–20 (Dr. Feuerstein testifying that gyroscopes “can be used to detect angular velocity”); Ex. 1047 ¶ 47 (citing Ex. 1051, 170; Ex. 1053, 9) (Dr. Buehrer testifying that a person of ordinary skill in the art “would understand that gyroscopes are well-known inertial sensors that specifically detect rotational motion”).

      “whether Kalliola’s teaching of pausing and resuming its DoA estimation based on detected rotational motion, or Kalliola’s teaching of speeding up its DoA estimation based on detected rotational motion, amounts to determining direction based on rotation. Pet. 63–64; PO Resp. 25–27; Reply 24–27; Sur-Reply 11–14. On the record developed during trial, we are persuaded that the preponderance of the evidence supports a finding that Kalliola teaches determining direction based on rotation. First, Kalliola discloses “pausing a DoA estimation until the motion of the WCD is detected by the motion sensors,” then resuming “the updating of the DoA estimation” when motion is detected. Ex. 1004 ¶¶ 14, 84. Second, Kalliola discloses a “correction or compensation mode” that is “employed when user 110 moves WCD 100 too quickly for an accurate DoA estimation,” with this “increase[d] speed of the DoA estimation” being triggered by the “[i]ncreased activity detected by motion sensors in WCD 100.” Id. ¶ 86. As discussed above with respect to limitation 11(d), the detected motion that triggers either of these modes can be rotational motion of the WCD detected by a gyroscope.” slip op. at 22

Petitioner fails to provide anything to explain how or why the plain meaning of “each” and “respective” in the context of limitation 1.2 could be understood by a skilled artisan to connote something other than the plurality of bits individually identifying a separate and distinct time interval (i.e., a “one-to-one correspondence”). Petitioner similarly does not identify anything from the specification of the ’416 patent that would support deviating from the plain meaning of limitation 1.2. And Petitioner’s reliance on 3M Innovative Properties appears to miss the mark. Pet. Reply 7. In that case, the Federal Circuit held that, when a claim term has an “ascertainable definition in the body of the claim,” their “cases do not support prescribing a more particularized meaning unless a narrower construction is required by the specification or prosecution history.” 3M Innovative Properties Co., 725 F.3d at 1329. Here, however, Patent Owner is not attempting to import a more particularized meaning into limitation 1.2, but to demonstrate that the ’416 specification is consistent with the ascertainable definition of “each” and “respective” within the context of limitation 1.2. In particular, Patent Owner highlights that the ’416 specification describes the resource allocation technique as using an indicator bit, within a plurality of indicator bits, that has a one-to-one correspondence to a specific time window established for a Forward Access Channel (FACH). See Ex. 1001, 13:63–14:25, 14:44–53, Figs. 7, 9; PO Resp. 11–14, 19–20; PO Sur-reply 2–3; Ex. 2001 ¶¶ 36–40, 49. And we agree that the ’416 specification informs, and is consistent with, the plain reading of limitation 1.2. See Ex. 1001, 13:63–14:25, 14:44–53, Figs. 7, 9. Therefore, we determine that the plain and ordinary meaning of limitation 1.2 requires all the plurality of bits to individually identify a separate and distinct time interval that physical shared channel resources are utilized to signal channels.” slip op. at 12

      “PICH, which is communicated to Kim’s receiver, has a plurality of bits, the evidence fails to demonstrate sufficiently that each of those bits indicates a respective time interval that physical shared channel resources are utilized to signal channels, as limitation 1.2 recites. As Patent Owner correctly argues, the Vayanos paging indicators use multiple bits to indicate information about a single time interval in a frame, rather having several bits that individually identify a separate and distinct time interval. PO Resp. 39–41 (citing Ex. 2001 ¶¶ 67, 74–75). Vayanos teaches that “[t]he number of paging indicators (Np) in each PICH frame is configurable by the system and can take on a value of 18, 36, 72 or 144,” and that “[e]ach paging indicator is sent in 288/Np consecutive bits in the PICH frame, where 288/Np can take on a value of 16, 8, 4 or 2.” Ex. 1006, 3:26–34. As a result, if there are 18 (Np = 18) paging indicators, 288/NP = 288/18 = 16 (meaning that each paging indicator is 16 bits long), if there are 36 (Np = 36) paging indicators, 288/Np = 288/36 = 8 (meaning that each paging indicator is 8 bits long), if there are 72 (Np=72) paging indicators, 288/Np = 288/72= 4 (meaning that each paging indicator is 4 bits long), and if there are 144 (Np=144) paging indicators, 288/Np = 288/144 = 2 (meaning that each paging indicator is 2 bits long). Ex. 2001 ¶ 66. Each paging indicator (singular) taught by Vayanos includes multiple bits––each paging indicator (singular) has either 16, 8, 4 or 2 bits–– and Vayanos does not disclose or suggest a paging indicator that indicates a time interval with only a single bit. Id. And Petitioner does not cite Kim to show the number of bits used to indicate a time interval; only to show that a UE would receive broadcast information with paging information including paging indicators that identify a time interval in which physical shared channel resources are utilized to signal channels. See Pet. 40–49. Even accepting that the Kim/Vayanos combination discloses a UE receiving a paging indicator that is indicative of a time interval in which a Paging Channel PCH may be found or indicative of whether a frame will include a signaling channel (e.g., PCH) at a specific TTI within that frame, the combination does not disclose or suggest using a paging indicator that is a single bit indicating either of those time intervals. On the contrary, as noted above, Vayanos teaches that all paging indicators consist of multiple bits and, thus, the Kim/Vayanos combination discloses a UE that only receives and uses a plurality of bits to indicate a time interval that physical shared channel resources are utilized to signal channels. This is insufficient to show a reasonable likelihood that Petitioner will be able to establish that the Kim/Vayanos combination discloses or suggests receiving a plurality of bits wherein the individual bits each identify a separate and distinct time interval. Therefore, Petitioner has not shown sufficiently that the Kim/Vayanos combination discloses or suggests the subject matter limitation 1.2 recites. For the above reasons, we are not persuaded that Petitioner has shown sufficiently that the combination of Kim and Vayanos disclose or suggest broadcast information that includes a plurality of bits, wherein each of the plurality of bits indicates a respective time interval that physical shared channel resources are utilized to signal channels. This failing undermines Petitioner’s showing as to independent claims 1 and 7 (in the asserted Grounds 1 and 2) and, as a result, the same deficiency extends through to all of the dependent claims challenged in all of the grounds.4” slip op. at 18

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

      “Although we agree with Petitioner that the plain meaning of limitation 1.2 does not require the recited determination to occur at the first well, it does require the determination to be about the condition(s) of the fluid communicated to the first well by the manifold, regardless of where or how the information is gathered to make that determination. Limitation 1.2 recites plainly that the “determining” step is specifically about whether “the fluid communicated via the manifold has satisfied one or more conditions.” Ex. 1001, 22:38–39 (emphasis added). Considering the antecedents for “the fluid” and “the manifold”––i.e., “communicating fluid to a first well via a manifold” (id. at 22:35, limitation 1.1)––limitation 1.2 expressly identifies the fluid which “the manifold” has “communicated” to the first well to be exactly the fluid used for “determining” whether “one or more conditions” are “satisfied” to trigger the recited responses. Id. This is because “the fluid” refers to a fluid passing to a first well by way of a manifold and the past tense of “communicated via the manifold” indicates, more specifically, that it is the fluid passed by the manifold which must satisfy a condition(s). The Specification of ’770 patent illustrates this by checking the “frac rate” of the fluid discharged by a manifold to a first well to make the determination about whether to permit a regular swap or a continuous pumping swap (“CP swap”). Ex. 1001, 13:30–54, Fig. 12. Therefore, contrary to Petitioner’s representation that limitation 1.2 does not “requir[e] the fluid used for ‘determining’ to have been communicated to the first well” (Pet.

    • Strike new argumentNew argument disregardedDecided for patent owner

      “We determine that the Petition did not adequately present Petitioner’s contention that Tolman discloses or suggests a “master valve” that a skilled artisan would understand to be the claimed “first valve,” which is first introduced in the Reply. The issue is whether Petitioner’s identification of Tolman’s “tree valve” for the claimed first valve was particular enough to allow Petitioner to rely specifically on the “master valve” in the well tree to show Tolman discloses the first valve. We find that it is not. It is undisputed that a well tree include several different valves: (1) valves for communicating fluid to a well (e.g., for treatment or stimulation); (2) valves for communicating fluid from a well (e.g., for flowback); and (3) valves for communicating fluid both to and from a well (e.g., master valve). See Reply 19–20; Ex. 1002 ¶¶ 542–545; Ex. 1044 ¶¶ 33–34, 38–42; Tr. 33:12–18, 34:3–12, 36:8–37:18, 39:4–17; Ex. 2013, 85:4–86:19, 87:1–12, 89:2–11. And the opening/closing of these different valves are controlled independently of the other valves based on different parameters. Id. identifying a tree valve, generally, does not provide the particularity necessary to provide notice that the master valve is the particular valve being relied upon. Further compounding this problem is the fact that the Petition repeatedly refers to a plurality of valves, rather than a singular “master valve.” The variability of possible valves suggested by simply referring to a tree valve fails to provide a level of particularity that clearly identifies which specific structure is being relied upon to perform which part of the recited procedure. Ultimately, we agree with Patent Owner that because the Petition does not specifically identify the master valve in the Petition, which the Petitioner’s Reply suggest was the intention all along, Patent Owner was put at a disadvantage because its ability to fully develop a response was impeded. Therefore, Petitioner’s reliance particularly on the “master valve” of the well tree, and the newly introduced evidence associated therewith, was improper and may not be considered. Nevertheless, as discussed below, even if Petitioner were allowed to rely on the master valve, we still find the Tolman Grounds to be deficient.” slip op. at 56

      “However, Carr does not disclose or suggest: relying on the condition(s) of the fluid communicated by first isolated manifold path 122 to first well 140 to be the determinative factor for causing first and second valves 470 and 472 to perform a sequenced response that includes–– (1) opening second valve 472, (2) communicating fluid to second well 142 through second valve 472, and (3) after opening second valve 472, closing first valve 150 from communicating fluid to first well 140. At the time of the invention, when a first well is being operated individually using high pressure pumping, we find that skilled artisans would have considered concurrent operation of the second well’s valves to be hazardous and activities that can not occur. See Ex. 1031, 4 (“specifically identified activities that were restricted from occurring at the same time (i.e., CAN NOT OCCUR activities). As an example, if the operations on a well involved high pressure pumping . . . then manipulating manifold well valves and wellhead trees valves on another well were not allowed to be performed concurrently”); Ex. 2012 ¶ 148. would have had a reasonable expectation of being able to successfully avoid the unacceptable hazards known to be associated with opening second valve 472 and communicating fluid to second well 142, while individually operating on first well 140 using high pressure pumping.10 Furthermore, Petitioner provides no persuasive evidence that a skilled artisan would have known that those unacceptable hazards could be avoided (or acceptably minimized) by using a condition(s) of the fluid communicated by first isolated manifold path 122 to first well 140 as a trigger for opening second valve 472 and communicating fluid to second well 142, while first well 140 is being individually operated.” slip op. at 34

      “large obstructions that force the air flow to near the peripheral surface of the housing, render the passageway non-central. During prosecution of the ’864 patent, the Examiner rejected certain claims (i.e., dependent claims 49, 63, and 75) over Han. To overcome this rejection, the applicant argued that Han cannot meet the limitation “wherein the airflow passageway extends centrally and axially from the first aperture to the second aperture.” Ex. 1002, 273. The applicant explained that Han does not meet this limitation because Han’s shell (b) does not include a central airflow passageway and instead places the perforated component for liquid storage (9) in the middle of shell (b), thereby forcing the airflow around the peripheral surface of the perforated component for liquid storage (9). Id. at 273–274. The examiner relied on this argument in determining that the applicant had overcome an earlier rejection. Id. at 195.

On the record developed during trial, we agree with Patent Owner that Petitioner has not shown by a preponderance of the evidence that a person of ordinary skill in the art would have had a reason to combine the teachings of Xia with those of Wang to arrive at the claimed limitations. Relying on the testimony of Patent Owner’s declarant Dr. Singhose, Petitioner argues that a person of ordinary skill in the art “would have known a central straight path has less airflow resistance than a circuitous one.” Reply 22 (citing Ex. 1035, 127:15–128:9). But the same witness also testified that higher airflow resistance might be desirable and explained that providing more resistance to airflow might result in improved mixing. Ex. 1035, 21:21–22:12, 127:20–24, 170:10–14. In addition, Dr. Singhose testifies that the complicated design of the airflow passageway in Xia “serves important functions,” including “allow[ing] large droplets to be reabsorbed by the liquid-guiding mechanism,” allowing “excessive liquid in the airflow [to] condense,” and “prevent[ing] the chemical liquid from being sucked into the mouth.” Ex. 2022 ¶ 190 (citing Ex. 1004, 11, 13–14, 16). Although Petitioner’s declarant Dr. Sturges testifies that a straight airflow passageway “would provide improved, smoother air flow,” he does not provide any evidence supporting the view that the air flow would be improved.
