“(1) a person with a B.S. in engineering or an equivalent field, with two-four years of academic or industry experience in aspiration embolectomy and thrombectomy or comparable industry experience who would, where appropriate, work or consult with others, including a physician, to develop embolectomy or thrombectomy devices; or (2) an interventional neurosurgeon with at least three years of experience developing and/or using medical devices in embolectomy or thrombectomy procedures, and who would, where appropriate, work or consult with others, including an engineer, to develop such a medical device. 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.

“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

“appear to be that Patent Owner specifies that the POSA’s knowledge and experience may include optical sensors and that the POSA may have a degree emphasizing software. We do not deem these differences material, particularly because the optical sensors and technologies at issue are those used in physiological monitoring technologies and both parties agree that the POSA would have a working knowledge of physiological monitoring technologies. Ex. 1003 ¶ 24; PO Resp. 11. We find the additional specificity of Patent Owner’s definition to be helpful. In addition, Patent Owner’s definition appears to be consistent with the level of skill in the art reflected in the prior art of record and the disclosure of the ’507 patent. Accordingly, we adopt Patent Owner’s proposed definition of the person of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Our inability to find a teaching of averaging in Mendelson is consistent with the testimony of Drs. Kenny and Duckworth. Dr. Kenny testifies that “there is simply no disclosure in Mendelson itself of any summing or averaging of collected signals.” Ex. 1083 ¶ 23.

See Ex. 1087, 103:9–114:11 (confirming that certain aspects of his declaration testimony relating to averaging of signals are not discussed in Mendelson).

That is not, however, the standard for inherency. It must be the necessary result, not a possible expected result. The Federal Circuit in Par explained that: Inherency, however, may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient. If, however, the disclosure is sufficient to show that the natural result flowing from the operation as taught would result in the performance of the questioned function, it seems to be well settled that the disclosure should be regarded as sufficient.” slip op. at 28

“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).

“scenarios. Pet. 1 (characterizing three claimed scenarios as (i) an “inadvertent” contact, (ii) a “tap” contact, and (iii) a “hold” contact), 4 (“Independent Claims 1 and 42 outline three scenarios regarding a user’s contact with a touch screen device”); Prelim. Resp. 3 (“With respect to claim 1, these three scenarios include: . . . .”); see Ex. 2001 ¶¶ 28 (“As recited in claim 1, the three different claimed functionalities are executed ‘when’ the prerequisite elements are met (described as three scenarios by Dr. Cockburn.”) (citing Ex. 1001, 102:50–103:55; Ex. 1003 ¶¶ 33–35), 29–32 (describing the first, second, and third scenarios). In substance, the parties’ dispute appears to concern whether the plain language of the claims requires that a recited function must be performed only after or in response to expiration of a threshold (and other prerequisites), as opposed to requiring a function that begins before and continues after expiration of a threshold. Notably, dependent claim 3 recites: “The electronic device of claim 1, wherein the electronic device is configured such that the first feedback that is perceptible by touch is output prior to the display of the menu.” Ex. 1001, 104:1–4 (emphasis added). Given that independent claim 1 is necessarily broad enough to include claim 3, it seems on this record that the functions recited in Limitation [1.o] necessarily can happen at different times, as opposed to, for example, only responses that are triggered by the so-called “prerequisite elements.” We encourage the parties to address this issue as a matter of claim interpretation in future briefing. Based on the current record, however, we determine that it is not necessary to provide an express interpretation of any claim terms at this stage of the proceeding. See Realtime Data, LLC v. Iancu, 912 F.3d 1368 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’” (quoting Vivid Techs., Inc. v. Am.

“Petitioner contends that the challenged claims do not need construction to demonstrate unpatentability. Pet. 14. Petitioner, however, notes that the parties in the ITC proceeding identified above dispute the meaning of several claim terms. Id. (citing Ex. 1026). Petitioner specifically notes that “the parties dispute what is required of independent claims 1, 5, and 16 to ‘determin[e] how many pixels’ to filter in each block.” Id. (citing Ex. 1026, 6–7). Petitioner argues that “ITC Respondent Lenovo mathematical basis (no relationship) with the pixel values of the pixels in said neighboring block’” (id. (citing Ex. 1026, 6–7)), but Patent Owner “contends that no construction is necessary,” “and the ‘plain meaning’ does not foreclose some ‘mathematical basis’ existing as long as separate decision values are calculated for each block” (id. (citing Ex. 1027, 14–19)). Petitioner indicates that Ground 1 adopts Patent Owner’s broader construction from the ITC proceeding and Ground 2 adopts Lenovo’s narrower construction. Id. at 14–15. Patent Owner argues that “none of the asserted grounds disclose or render obvious the Challenged Claims under the plain meaning of the claims (which is [Patent Owner’s] proposed construction) or under Lenovo’s narrower proposed construction.” Prelim. Resp. 29. On the present record, we do not discern a need to construe explicitly any claim language because doing so would have no effect on our analyses below of Petitioner’s asserted grounds and will not assist in resolving the present controversy between the parties.

“Furthermore, we are not persuaded that modifying Aksu in view of Gonzalez in the manner proposed by Petitioner overcomes this problem. As noted above, Petitioner asserts that, in the proposed combination, one of ordinary skill in the art “would have understood that the Laplacian’s output would be compared directly to a threshold based on β—just like Aksu’s difference calculations—to determine how many pixels to filter.” Pet. 60 (citing Ex. 1019, 13:15–19; Ex. 1003 ¶¶ 406–410). We disagree with this assertion, however, because it relies on erroneously equating the output of calculations (i.e., |r1-rj| and |r1-ri+1|). In other words, Aksu’s difference calculations, although used in setting dr, are not the same as dr; and we are not persuaded that one of ordinary skill in the art would have considered comparing Gonzalez’s Laplacian output to threshold β because Aksu discloses comparing its difference calculations to β. As noted above, we are not directed to any disclosure in Aksu of comparing dr to β. In addition, Dr. Schonfeld’s testimony on this point is not persuasive. Specifically, Dr. Schonfeld testifies that “dr can simply be defined as the output of the Laplacian (dr=|r3-2r2+r1|), and dr could be directly compared to a threshold based on β.” Ex. 1003 ¶ 408 (underline emphasis added). This testimony, however, is entitled to little weight because Dr. Schonfeld fails to provide a sufficient underlying basis for his opinion. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); see also Nobel Biocare Services AG v. Instradent USA, Inc., 903 F.3d 1365, 1382 (Fed. Cir. 2018) (explaining that the Board can reject arguments based on expert testimony that lacks specificity or detail). Moreover, opining that output of the Laplacian, dr, could be directly compared to β does not establish sufficiently that one of ordinary skill in the art would have been motivated to do so. See Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015) (“[O]bviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed invention.”).” slip op. at 26

Dr. Mark P.

Pet. 60 (emphasis added). challenged patent itself raises the possibility that Petitioner has succumbed to impermissible hindsight bias. See Zoltek Corp. v. United States, 815 F.3d 1302, 1313 (Fed.

Cir. 2014) (“It appears that [the expert] relied on the . . . patent itself as her roadmap for putting what she referred to as pieces of a ‘jigsaw puzzle’ together.”). Even so, the preliminary record also indicates that it may be inherent in an NB-IoT system that “DCI indicating an SC-MCCH change notification must be transmitted in a different subframe from the DCI indicating a resource for the updated SC-MCCH information.” Pet. 61.

“We see no basis for using China Standard Time here. “The time and date of receipt of an application filed via EFS-Web is the local time and date in USPTO headquarters in Alexandria, Virginia.” Manual of Patent Examining Procedure (MPEP) § 502.05 I.C.2 (9th ed. Rev. 07.2015, Nov. 2015) (emphasis added).7 The MPEP provides an example of how an application filed from the Pacific Time Zone would receive the filing date as of the USPTO’s local time: For example, if an applicant in California officially files a patent application with the USPTO through EFS-Web by clicking on the SUBMIT button at 10 p.m. Pacific Time in California on May 1, that application would be officially received by the USPTO at 1 a.m., local time (i.e., Eastern Daylight Time) on May 2. Accordingly, the application would receive a filing date of May 2. Id. Thus, we disagree with Patent Owner’s argument that Fujishiro is not prior art for this reason. Prelim.
