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.

- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner
“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. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed.

“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

“Also, to the extent Masaba relies on extrinsic expert testimony, we note that Masaba’s expert cites absolutely no support for his understanding of the claims, much less explains why we should adopt his understanding over the plain and ordinary meaning of “conveying aggregate” and “moving aggregate.” See Ex. 2004 ¶ 34. Absent supporting citations, such extrinsic testimony is entitled to little, if any, weight.

- Skill levelSkill level petitioner adoptedDecided for petitioner
“We disagree that Dr. Durham does not possess the necessary level of skill in the art to qualify as an expert in this case. Looking at the specification of the ’689 patent and the prior art of record, we think Masaba sets the bar too high. We acknowledge that one of ordinary skill in the art should have some education and/or experience in the mechanical art of conveying aggregate materials, but we do not think opining on the ’689 patent and asserted prior art necessarily requires that person to have the amount of education and experience that Masaba advocates. The ’689 patent relates generally to an “aggregate transferring system for receiving aggregate from a vehicle and elevating the aggregate to a higher vertical level for deposit into, for example, a silo.” Ex. 1001, 1:15– 18. And, as described in the ’689 patent and discussed later, the transferring system is an assembly of known types of conveyors, such as a belly-dump truck conveyor, a bucket elevator, and an articulated belt conveyor, for transferring the aggregate horizontally and vertically from a belly-dump truck to the discharge point, such as a silo. Without doubt, Dr. Durham has enough education and experience to reliably opine on the combination of known parts.” slip op. at 8
- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Plain and ordinary meaningNo construction needed
“We reject this argument for several reasons. First, nowhere does the plain language of the claims specify how the aggregate is conveyed or moved from the conveyor extension assembly’s inlet to its outlet, be it passively by means of gravity or actively by means of a conveyor belt. Instead, the claims simply use those verbs according to their plain and ordinary meaning, which is “to transfer or deliver” or “to cause to go or pass” from one place to another. See Ex. 3001, 253 (defining “convey”), 760 (defining “move”).10 Second, the specification of the ’689 patent similarly uses these terms in a plain and ordinary sense, without ever attributing to them some sort of special meaning. See, e.g., Ex. 1001, 4:9–12 (“The apparatus 10 is suitable for performing the transfer of aggregate from 10 We reference the original pagination of the dictionary in which these definitions appear. one location to another, such as, for example, from a vehicle carrying the aggregate to a silo 1 for storing the aggregate.”). The ’689 patent specification also makes clear that active conveyance of the aggregate is an option and not a requirement of the claimed invention, stating that the conveyor extension assembly “may further include a conveyor belt 150.” Ex. 1001, 10:60–66 (emphasis added). Limiting claim elements 1[h] and 1[i] to a device “for actively conveying” or “for actively moving aggregate” would improperly import limitations from the specification into the claims. Thus, based on the intrinsic evidence, we determine that claim elements 1h and 1k are properly construed to encompass passive and/or active movement of the aggregate via the conveyor extension assembly.” slip op. at 20

See id. at 24–25. Only in disputing Solaris’s Ground 3 does Masaba advocate that the claim term “trailer structure” should be construed under § 112(f), and then only in conjunction with dependent claims 3 and 21. See PO Resp. 58. As such, we address Masaba’s proposed construction in our analysis of Ground 3. We now turn to Solaris’s grounds of unpatentability.” slip op. at 12

Patent Owner next contends that Kido does not disclose a first payout that is “for the spin of the roulette wheel.” Prelim. Resp. 29. Patent Owner’s argument is premised on the cumulative nature of Kido’s Prog bonus – it builds with every spin of the roulette wheel until won. Id. (“Each time the wheel is spun, 0.5% of the amount wagered is added to the progressive jackpot, and thus, the jackpot’s value reflects multiple spins of the roulette wheel.”). Thus, according to Patent Owner, the value of the jackpot is determined using multiple spins of the roulette wheel and is not “for a spin of the roulette wheel” as claimed.” Id. at 30. The claims, however, only require a first payout that is higher than a second payout. Nothing prohibits the higher payout from accumulating from prior spins of the roulette wheel because, when it is actually won, it will be for that last spin of the roulette wheel. Ex. 1005, 8:35–36 (“indicating that the first player is to be paid at the first payout for the spin of the roulette wheel”). Regardless of how Kido’s Prog bonus accumulated, it is paid for a spin of the roulette wheel – at that juncture Kido discloses each claim element. Anticipation occurs when a prior art reference discloses every element of a patent claim at a point in time, as Kido does with a single spin of the roulette wheel that pays the Prog bonus. As persuasively explained by Petitioner, “the steps of Figure 12 (including A13) occur within a single round of roulette, for a single spin of the roulette wheel, until the routine ‘returns to the step of A1 and is transited to a next game.’” Pet. 39 (quoting Ex. 1007 ¶ 233).” slip op. at 13

“(iii) Analysis Based on the present record, we determine Petitioner’s contentions regarding the third step of claim 1 are supported sufficiently by the cited disclosures in Weese and Dr. Peterson’s testimony to justify institution of review. In particular, Weese describes obtaining a plurality of second images of the patient’s internal organs (i.e., PET image I0 in Fig. 1, and PET image I10 in Fig. 3) using a second imaging technique (i.e., PET). See Ex. 1005, Figs. 1, 3, and 6, ¶¶ 47–49, 58–59, 72. In particular, PET image I0 in Figure 1 may be a reconstructed “volume image[]” composed of a plurality of “quasi two-dimensional” “slice images” that, when combined, represent a three-dimensional region inside the patient. Id. ¶¶ 48, 58, 61; see also Pet. 56–57. PET image I10 in Figure 3 may be a similarly reconstructed volume image composed of a plurality of slice images.4 See 4 We do not rely here on Petitioner’s alternative theory that Weese discloses a “plurality” of second images because PET images I0 and I10 are “superposed” images encompassing “several states of motion.” Pet. 58. Ex. 1005 ¶¶ 61, 83–84. Patent Owner’s sole opposition to Petitioner’s assertions in this regard are limited to whether Weese “obtain[s]” PET images I0 and I10 as recited in claim 1, which we address below. Also, it appears that PET images I0 and I10 are obtained while also obtaining second movement measurements of the patient’s internal organs using a second sensor system (i.e., motion acquisition unit 12 and motion sensor 15 / S1) which is independent from the PET imaging technique. See Ex. 1005, Figs. 1 and 6, ¶ 65 (“[T]he respiratory motion is determined during the acquisition of the PET projections P1 by means of a respiratory motion sensor provided on the patient and therefrom the frequency function f(r) or, more generally, a state of motion function F1 is derived for the construction of the motion model M2.”). Furthermore, Weese describes how frequency function f(r) is utilized to facilitate image comparison between CT and PET images at common motion states. See id. ¶¶ 31, 49–51, 70–71, 75–77, 79–80, 83; see also Ex. 1003 ¶¶ 214–216 (Dr. Peterson’s supporting testimony). Patent Owner’s sole opposition to Petitioner’s assertions in this regard are limited to whether Weese “obtain[s]” PET images I0 and I10 as recited in claim 1, which we address below. Patent Owner’s two opposing arguments are unavailing, based on the present preliminary record. First, Petitioner relies on reconstructed PET images I0 and I10 as satisfying the “plurality of second images” recited in claim 1, not PET projections P1 from which PET images I0 and I10 are derived. See, e.g., Pet. 56, 58 (“I0 and I10 disclose and render obvious a ‘plurality of second images’ in two ways” — “I0 and I10 may be ‘volume images’ formed using ‘known’ techniques,” and “I0 and I10 are ‘superposed’ PET images encompassing ‘several states of motion,’ which” slip op. at 18

“According to Petitioner, “no express constructions are required in this proceeding.” Pet. 4. Patent Owner “agrees that the terms of the ’728 Patent have their plain and ordinary meaning.” Prelim. Resp. 7. However, Patent Owner contends that Petitioner construes the claim language “during the driving period” to mean “throughout the driving period.” Id. at 10 (claim language found in claims 1, 13, 24, and 25). Patent Owner contends Petitioner consistently uses the term “during” rather than “throughout” in the analysis of the challenged claims. Id. Patent Owner does not provide support for any specific construction or explain why any claim construction would be necessary for resolution of this proceeding. Based on the current record, we determine the differentiation asserted by Patent Owner between the use of “during” and “throughout” does not require express interpretation as the terms “during” and “throughout” are synonymous.8 Upon review of the record, we determine that no claim terms require express construction for purposes of this Decision. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (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 and Dr. Michalson propose “that a person of ordinary skill in the art in this matter would have had at least a Bachelor of Science Degree (or equivalent) in an academic area emphasizing electrical engineering, computer engineering, computer science, or a related technical field, and about 2-3 years of experience in the field of telematics systems.” Ex. 1003 ¶ 15; Pet. 2, 11. Dr. Michalson further proposes “[a] greater amount of education, e.g., a doctorate in an academic area emphasizing electrical engineering, computer engineering, computer science, or a related technical field, would compensate for fewer years of work experience.” Id. Patent Owner does not dispute this level of skill. See generally Prelim. Resp. For purposes of this Decision, we adopt Petitioner’s proposal, which comports with the teachings of the ’728 patent and the asserted prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

“Based on our review of the preliminary record, we conclude Petitioner has explained with supporting evidence how the combination of Callopy, Curry, and Thompson teaches or suggests claim 1, sufficiently to justify institution of review. That is, Petitioner explains how a person of ordinary skill in the art would have been motivated to supplement the risk assessment capabilities of Callopy-Curry with the well-known accident detection techniques of Thompson’s WreckWatch application to reduce vehicular accidents and casualties. For the purposes of institution, Petitioner has articulated a reasoned explanation why a POSITA would have been motivated to modify Callopy’s wireless device with Curry’s calculation techniques, and Thompson’s accident detection capabilities. The Petitioner has explained in detail that Curry contemplates the need for multi-modal operation for nuanced driving conditions, and that the incorporation of Callopy would be a natural modification that aligns with standard insurance evaluation methods. Petitioner further explains the implementation of Curry’s scoring system, which is capable of logging data and processing safety statistics, in combination with Callopy’s system leads to enhanced sensor-based driving evaluation in the determination of a driver’s risk profile for insurance purposes. Petitioner further explains in detail how Thompson’s implementation further provides motivation for Curry’s initiatives to “reduce traffic-related fatalities and injuries” and that a POSITA would seek the well-known accident detection technique of Thompson to achieve this. Petitioner identifies that the combination of Callopy, Curry, and Thompson not only can be achieved without any changes to underlying hardware, but also provides the functionality of recording sensor data relating to driving, calculating driving safety statistics, and detecting driving-related incidents. Moreover, as discussed, Petitioner has provided citations to the references along with corroborating testimony from Dr. Michalson that support its arguments for why and how a POSITA would have combined the prior art disclosures with a reasonable expectation of success.

Vizio IPR, Paper 12; see also Vizio IPR, Paper 1 (the “Vizio Petition”). Petitioner here challenges the same claims and asserts the same grounds of unpatentability as those on which we instituted the Vizio IPR. Compare Pet. 1–2, with Vizio Petition, 1–2. Petitioner also relies on an identical declaration from the same declarant as relied upon by the petitioner in the Vizio IPR.

“trial allays concerns about inefficiency and duplication of efforts.” Fintiv, 6. However, when there is a parallel district court litigation and an ITC investigation, “district court litigation is often stayed under 28 U.S.C. § 1659 pending resolution of the ITC investigation.” Id. at 7. The fact that the parallel district court litigation is stayed is, therefore, not the focus of this Fintiv factor under these circumstances. Instead, Fintiv counsels that “the parties should indicate whether the patentability disputes before the ITC will resolve all or substantially all of the patentability disputes between the parties, regardless of the stay.” Id. at 9. Here, the parallel ITC investigation is not stayed and, as we explain below in our analysis of Factor 4, there is some overlap between the patentability disputes presented here and those presented at the ITC. Petitioner argues that the district court is “not bound to any ITC decision” (Pet. Reply 2), but as Fintiv reminds us, “even though the Office and the district court would not be bound by the ITC’s decision, an earlier ITC trial date may favor exercising authority to deny institution under NHK if the ITC is going to decide the same or substantially similar issues to those presented in the petition.” Fintiv, 8.” slip op. at 9

“While Petitioner addresses all limitations of the challenged claims in its Petition, Patent Owner presents arguments under all three grounds raising issues with Petitioner’s challenges. For example, regarding the first ground, Patent Owner argues Okubo’s image cutout “does not represent a portion of a larger input image, but rather is the size of the image that is ‘picked up’ and recorded in the first instance.” Prelim. Resp. 12. Thus, according to Patent Owner, Okubo does not disclose “selecting sub-frames” as recited by limitation 1[D] of claim 1. Id. Regarding the second ground, Patent Owner argues that Okubo’s two-stage lens distortion correction process is limited to still images while Sokeila’s teachings relate to video images. Id. at 18–19. Regarding the third ground, Patent Owner argues that “Eder does not disclose selecting sub-frames representing portions of the input images, where the input images include fields of view captured through a lens of the camera.” Id. at 21.
