Pet. 11 (citing Ex. 1005 ¶ 48). Petitioner also contends that, “[a] person with less education but more relevant practical experience, or more relevant education but less practical experience, may also meet this standard.” Id. Patent Owner states that for purposes of its PO Response, it “accepts ¶ 44). We adopt Petitioner’s characterization because it is consistent with the level of skill in the art at the time of the invention as reflected by the ’402 patent and the cited prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown” (quoting Litton Indus.

“specification explicitly includes sensors similar to those in the prior art in support of their argument that the claimed “predetermined cycle” must not exclude the use of such sensors. Pet. Reply 15 (citing Ex. 1001, 32:55–33:7, 40:66–41:5, 44:9–29). We reviewed the portions of the specification cited by Petitioner. We agree with Patent Owner that one excerpt discussing sensor use appears to be directed to triggering the predetermined cycle rather than causing timing changes during the cycle itself (Ex. 1001, 32:55–66) (describing use of a pressure sensor to “determine when the vacuum channel 3 is clogged by a thrombus and automatically perform the unclogging procedures described herein”), while another excerpt discusses a sensor that Petitioner that the ’402 patent discusses the use of sensors to “tune” the system and that such “tuning” can be done statically (setting the cycle timing in advance) or dynamically (adjusting the timing during the cycle itself). See Ex. 1001, 48:19–49:50. Overall, we find that these disclosures involving sensors demonstrate that sensors may be used in various ways in different embodiments. However, none of these disclosures explicitly discuss the use of sensors in conjunction with a “pre-determined cycle.” Therefore, we find that the ’402 patent specification’s discussion of “sensors” are not particularly informative as to the appropriate construction of a “predetermined cycle” and do not outweigh the other explicit disclosures of “predetermined cycle” in the patent. We next turn to the other intrinsic evidence discussed by the parties — the prosecution history. As discussed by Patent Owner, in the Notice of Allowance, the Examiner found that Garrison did not teach or suggest a “predetermined cycle” because Garrison’s controller “changed the cycle of opening and closing the valves based on feedback from sensors.” Ex. 1004, 86. We acknowledge that the patent applicant filed subsequent comments during prosecution in which they stated that they “do[] not concede that the Examiner’s characterizations of the terms of the claims and the prior art are correct.” Id. at 29. However, we agree with Patent Owner that the importance of the Examiner’s statement in the Notice of Allowance does not rely on it being an express disclaimer (a standard which it does not meet). PO Sur-reply 8. We also considered Petitioner’s contention that the Examiner’s interpretation of Garrison may have been in error (PO Resp. 16); however, even if this were true, the Examiner’s statement still provides helpful insight into how the Examiner was interpreting the term sensors to change the opening and closing of valves during a cycle was not a “predetermined cycle.” Id. at 86. In sum, we find that Patent Owner’s proposed construction is consistent with the usage of the term “predetermined cycle” in the ’402 patent specification and prosecution history. Thus, after considering all of the cited evidence, we construe “predetermined cycle” to mean that “the timing of the sequence of valve operations in the cycle is determined beforehand, i.e., fixed, rather than varying based on feedback after operation begins.”” slip op. at 14

“2. Other Terms The parties also provided proposed constructions for the limitations of “[limited/limiting] to a positive amount of exit flow” and “control[ling] fluid flow in and out from the distal end of the catheter.” See Pet. 15–16; Pet. Reply 1–8; PO Resp. 22–24; PO Sur-Reply 2–6. However, having evaluated the arguments and evidence before us, we determine that construction of these terms is not necessary for purposes of this Decision. See Nidec Motor Corp. v.

“We agree with Patent Owner that neither Petitioner nor Mr. Brown propose any combination of Yang and Mullins that does not include Mullins’s pressure sensor in order “to control fluid flow in and out from the distal end of the catheter.” Indeed, in addressing the “predetermined cycle” limitation, Mr. Brown contends that Mullins discloses a “cycling controller that ‘varies aspiration pressure according to sensed pressure within the catheter lumen.’” Ex.1005 ¶¶ 131–32 (citing, e.g., Ex.1008, 27:40–28:20 (“[a] novel aspect of this pump system is the incorporation of feedback into the pump algorithm in order to produce more effective pressure cycling”)). This use of a sensor to change pressure during a cycle, is not a “predetermined cycle” under our construction. combinations is its discussion of distal end flow control, not for its sensors.” Pet. Reply 17 (citing Ex. 1035 ¶ 83). However, Petitioner’s obviousness grounds rely on the combination of Yang and Mullins, especially with regard to Mullins’s disclosure of “a controller” in order “to control fluid flow in and out.” As discussed above, Mullins relies on the sensor-feedback approach in order to control flow and we find that Petitioner has not presented persuasive evidence of how the combined disclosures of Yang and Mullins would control flow without using Mullins’s sensor feedback approach. See W.L. Gore & Assocs., Inc. v. Garlock, Inc., 721 F.2d 1540, 1550 (Fed. Cir. 1983) (error to “consider[] … references in less than their entireties, i.e., in disregarding disclosures in [them] … that diverge from and teach away from the invention”). Therefore, we determine that Petitioner has not sufficiently shown that the combination of Yang and Mullins discloses or renders obvious “a controller configured to open and close the vacuum valve and the vent valve in a predetermined cycle to change a level of vacuum at the distal end of the catheter and to control fluid flow in and out from the distal end of the catheter.” Accordingly, having considered the parties’ respective evidence and arguments, we find that Petitioner has not shown by a preponderance of the evidence that claim 1 of the ’402 patent would have been unpatentable as obvious over the combination of Yang and Mullins.” slip op. at 27

“The respective proposed levels of qualifications for a person of ordinary skill in the art are similar, with Patent Owner proposing two years of experience compared to Petitioner proposing significant experience with remotely controlling fluid-handling devices, like SCADA systems. Patent Owner also proposes more extensive experience in lieu of educational experience. While we find Petitioner’s proposed qualifications to be acceptable, we adopt Patent Owner’s proposed qualifications for the purposes of this Decision because they offer a wider range of qualifications that nonetheless comport with the level of skill necessary to understand and implement the teachings of the ’871 patent and the asserted prior art.

We agree with Patent Owner that the Petition fails to demonstrate that Kahn discloses or teaches these limitations because the evidence does not provide support that there is remote control of fluid handling devices or the use of a user command on a control interface to send a command to a fluid handling device, for instance. Kahn is directed to providing access to fluid sensing data and analyzing and providing visual information on that data, but we do not discern that it teaches or discloses the capability to remotely control fluid handling devices. See, e.g., Ex. 1005, code (54), 1:27–36, 2:50–3:2. More specifically, the Kahn disclosures that Petitioner repeatedly relies upon for allegedly teaching this control are deficient. See Ex. 1005, 10:62–67, 14:35– 15:2, 15:62–16:32; see also Pet. 12–14, 16–18. Kahn discloses that “the communication unit 112B can include on-site alerts such as optical (indicator lights), audible alerts (e.g., alarm sounds), tactile (e.g., vibration of the unit) or can be interfaced to an appropriate control valve for simply shutting off the supply of fluid upon the detection of emergency events, for instance.” Ex. 1005, 10:62–67. Communication unit 112B is part of the local “sensor unit,” wherein the detection conditions determined by the sensor are communicated to remote devices by communication unit 112B. See id. at 3:31–33, 5:62–6:2, 6:27–35, 7:33–37, 13:7–12, Figs. 1A–1C. Kahn discloses that the sensor units, which include communication units 112B, can be located near shut-off valves and can communicate with distant locations. See id. at 11:1–13. There are no disclosures, however, in the above passages that there is remote control of fluid handling devices, that there is a user command on a control interface that actuates an actuator, or that there is a command sent to the facility actuators via a network connection, as required in limitations [18.5]–[18.7] and [18.9]–[18.12], respectively. Rather, the disclosure indicates that the communication unit 112B includes on-site alerts and that the local (non-remote) communication unit 112B can be interfaced with the control valve.” slip op. at 18

“On balance, we find that even with the alleged disadvantages identified by Patent Owner, one of ordinary skill in the art would have been motivated to modify Szrek with Llach’s third-party transaction processor because the advantage of having a “centralized intermediary” allows Szrek’s system to support different game providers, such as different lottery companies, which would reduce some implementation costs and allow the system to be more easily and cheaply extended.

“Neither party contends that any claim terms require an express construction to resolve the present controversy. Pet. 8 (“For purposes of this Petition only, Petitioner does not believe any terms require a formal construction.”); see generally Prelim. Resp. Nonetheless, Petitioner explains that the Petition is structured such that “Ground 1 is based on Patent Owner’s infringement contentions in the district court litigation, where the claimed ‘MUD module’ is generally mapped to multiple-input multiple-output (MIMO) receivers in a wireless network.” Pet. 2. Petitioner contends that “[u]nder this broad interpretation of a ‘MUD module,’ Walton’s MIMO receiver renders every challenged claim obvious.” Id. In contrast to Ground 1, the Petition states that “Ground 2 is based on the plain meaning of ‘MUD module,’ which is a component that detects, separates, and decodes signals from multiple users transmitting simultaneously over the same frequency band.” Id. Petitioner contends that, “[a]pplying the correct meaning of the term, Walton’s MIMO receiver does not necessarily comprise a MUD module.” Id. Therefore, Petitioner explains that “Ground 2 combines Walton with Learned, which expressly discloses [a] multi-user detector, and thus renders every challenged claim obvious in combination with Walton.” Id. at 2–3.7 In other words, the Petition presents Ground 1 and Grounds 2/3 as alternatives depending on the meaning of 7 Although not specifically relevant to claim construction, Petitioner explains that “Ground 3 further combines Walton and Learned with Quigley, to the extent Patent Owner argues Walton does not disclose providing a burst control input.” Pet. 3. “MUD module,” where Ground 1 is based on Petitioner’s understanding of Patent Owner’s interpretation of the term and Grounds 2 and 3 are based on Petitioner’s interpretation of the term as having its plain meaning. Petitioner further contends that “[e]very other claim term carries its ‘ordinary and customary meaning’ . . . .” Id. at 8. Although Petitioner presents a potential dispute regarding the meaning of “MUD module,” we need not construe this term expressly because the determination we reach herein does not depend on which meaning MUD module is applied. Accordingly, we do not construe any claim terms expressly because express constructions are not necessary to resolve the controversy before us. See Realtime Data, 912 F.3d at 1375.” slip op. at 12

“We find the Petition lacking in particularity because it does not clearly identify what aspect of Jin is alleged to teach the unique signal parameters (or unique estimated signal parameters) recited in claim 1. See, e.g., 35 U.S.C. § 312(a)(3) (“A petition filed under section 311 may be considered only if — (3) the petition identifies, in writing and with particularity, . . . the evidence that supports the ground for the challenge to each claim . . . .”). First, as reflected above, the Petition asserts that something called a “unique pilot parameter” teaches the recited unique estimated signal parameters. But “unique pilot parameter” is not a term or phrase recited in Jin. See Prelim. Resp. 19 (arguing the same). So, when Petitioner states “Jin discloses that the base station uses the unique pilot parameter (i.e., ‘unique estimated signal parameters’) to ‘identify which user (i.e., mobile terminal) has transmitted the received data,’” it is not clear what element in Jin Petitioner intends to identify by the term “unique pilot parameter.” Dr. Min’s testimony does not help resolve the ambiguity in the Petition. In particular, Dr. Min also refers to a “unique pilot parameter (i.e., ‘unique signal parameter’) for each user.” Ex. 1003 ¶ 89. But, as noted above, Jin does not disclose an element referred to as a “pilot parameter” and it is not clear what element Dr. Min intended to identify in Jin.8” slip op. at 18

“We agree with Petitioner that Oka is not cumulative of Jones. Jones discloses an impedance measuring system for measuring the impedance of each well of a multiwell plate. Ex. 1006, code (57). Moreover, Jones clearly teaches that the daughter boards in its system “may be equipped with multiple analog-to-digital converters.” Id. ¶ 18. Oka, in contrast, does not. As Patent Owner acknowledges, “Oka is a planar multielectrode array that 11 Oka et al., “A new planar multielectrode array for extracellular recording: application to hippocampal acute slice,” 93 J. of Neuroscience Methods 61– 67 (1999) (Ex. 1026) (“Oka”). measures via extracellular recording instead of impedance.” Prelim. Resp. 51 n. 10 (emphases added). This is consistent with the applicants’ arguments during prosecution that Oka does not disclose a multiwell plate, plurality of wells, or even measuring cell-substrate impedance. See, e.g., Ex. 1002, 191–193. Moreover, as Petitioner points out, Oka appears to disclose only a single ADC connected to a switch. See Ex. 1026, 63 (Fig. 2); see also Ex. 1002, 188 (applicant urging that “Oka uses a switch to connect the AD-C to different electrodes at different times” and therefore is not performing measurements for individual electrode arrays). Thus, unlike Jones, Oka does not disclose a plurality of ADCs, much less multiple ADCs arranged and operated in parallel such that impedances for multiple wells are measured at a time.12” slip op. at 28
