      “(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. 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. 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

      “As used herein, “impedance measurement at millisecond time resolution” refers to the ability to perform a series of at least two consecutive impedance measurements within milliseconds of one another for each and every well of the system where each well is associated with an electrode array for impedance measurement. In each instance the time between two consecutive impedance measurements are less than 300 milliseconds from one another. Id. at 10:8–15. There does not appear to be any dispute as to the definitional nature of the first sentence in the passage above. That is, the parties agree that millisecond time resolution should be construed to mean: “the time between two consecutive impedance measurements for each and every well being evaluated in the claimed apparatus or system.” PO Resp. 15 (proposing construction); Pet. Reply. 23 (“Axion also agrees that the term ‘millisecond time resolution’ is ‘the time between two consecutive impedance measurements for each and every well being evaluated in the claimed apparatus or system.’”). The parties also agree that we do not need to determine whether the time interval between two consecutive impedance measurements is less than 300 milliseconds, as set forth in the definition portion of the specification, or whether it can be met by some other time interval, as suggested by other portions of the specification. See e.g., Ex. 1001, 23:49–55 (explaining that “[i]n some embodiments 500 millisecond time resolution is sufficient”), 24:37–39 (similar); PO Resp. 15 (arguing that “the distinction between 300 milliseconds and 500 milliseconds is immaterial to the dispute in this IPR because Jones teaches a 1.5 second update period, thus at least three times longer than the 500 milliseconds formulation”); Pet. Reply 23–24 (section headed “[Petitioner] Agrees That, In This IPR, The 300 Versus 500 Milliseconds Distinction is Immaterial To Addressing the Unpatentability of the Challenged Claims”), see also, Pet. Reply 24–26 (asserting that the claims are indefinite because it is not clear whether they require a 300 or a 500 millisecond time interval, but arguing that “the claims’ unpatentability can be determined without resolving the 300 versus 500 milliseconds indefiniteness issue”). We agree with the parties that “millisecond time resolution” should be construed to mean: “the time between two consecutive impedance measurements for each and every well being evaluated in the claimed apparatus or system.” PO Resp. 15; Pet. Reply. 23. We further agree that resolution of this case does not require that we determine whether the period between two consecutive impedance measurements is less than 300 or less than 500 milliseconds because Petitioner has not carried its burden under either time interval.” slip op. at 7

      “Ex. 1003 ¶ 179. But Dr. Kim does not cite to any additional supporting evidence or provide any technical reasoning to support his statements. The notion that one can reduce the time between measurements by, e.g., reducing the number of frequencies measured, has intuitive appeal and appears mathematically correct. However, the absence of technical reasoning and supporting evidence diminishes the persuasiveness of Dr. Kim’s testimony that the POSA would made such modifications to reduce the time between measurements. Dr. Kim does provide some technical reasoning in connection with his discussion of eliminating all reference channels as a way to get the time resolution down to the levels required by, e.g., claim 14, which recites a millisecond time resolution of “less than 5 milliseconds.” See e.g., Ex. 1003 ¶ 172 (“A POSA seeking to study biological cell phenomena occurring on the order of a few milliseconds would have recognized that after measuring the reference network channels at the start, the reference network channels would not need measured again for some time, e.g., because temperature and other drift factors do not change appreciably on a millisecond time scale.”). However, even if we were to credit this testimony, Dr. Kim still lacks support and reasoning for the selection of the other parameters in his noreference-channel calculations. See, e.g., id. ¶ 173 (positing, but not providing technical reasoning for using, a no-reference-channel impedance system with 16 wells, a single 10kHz measurement frequency, and 16 daughter boards that measure simultaneously rather than sequentially).” slip op. at 29

      “Given that Jones’s only exemplified embodiment targets a 1.5 second update period, that Jones does not suggest reducing the update period, and that much of Jones’s focus is on benefits other than speed of measurement, Jones’s impedance analyzer seems an unlikely choice for a POSA seeking to take measurements having millisecond time resolution. Put another way, we find no persuasive non-hindsight reason that supports Petitioner’s assertion that the POSA would have sought to apply Jones’s impedance analyzer to Xu-752’s system in order to take measurements in millisecond time resolution.” slip op. at 22

      “Kwatra teaches, at Equation 7, minimizing velocity and acceleration of a function representing camera path (P). FF ¶¶ 6, 8–9. Kwatra does not state that this camera path function considers rotation. Rather, the words “camera path” suggest x, y, z movement of the camera rather than rotation of the camera. Dr. Foroosh’s testimony that Kwatra’s minimization of a smoothed camera path does not result in minimizing rotational velocity and acceleration is credible because this testimony is consistent with Kwatra as a whole and consistent with the other evidence of record. Id. ¶ 10. Kwatra recognizes that image rotation angle (“θ”) may not remain smooth. Id. ¶ 12. But rather than attempting to minimize velocity and acceleration of rotation of the camera housing, Kwatra states that applying a smoothness constraint on rotation angle “may be non-linear.” Id. ¶ 13. Consistent with Kwatra, Dr. Foroosh credibly explains the difficulty of applying linear techniques to rotation. Id. Thus, Kwatra proposes instead constraining the sine and cosine of theta. Id. ¶ 14. The Kwatra provisional application is part of the Kwatra reference (id. ¶ 15), and it similarly opts for simpler schemes rather than estimating all parameters for all frames jointly. Id. ¶ 16. The provisional explains that the rotational component is relatively small such that non-linear computations minimizing velocity and rotation can be avoided. Id. ¶¶ 17–18. The testimony of Patent Owner’s witness, Dr. Foroosh, explaining the provisional is credible (Ex. 2018 ¶ 72) because it is consistent with Kwatra’s complete disclosure. Dr. Foroosh’s testimony is more credible than the testimony of Petitioner’s witness, Dr. Katsaggelos, because Dr. Katsaggelos did not review the Kwatra provisional application and, thus, did not review the entire disclosure of Kwatra.

      “We review this testimony based on the strength of the underlying factual basis. 37 C.F.R. § 42.65(a); Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985) (“Lack of factual support for expert opinion going to factual determinations, however, may render the testimony of little probative value . . ..”). Here, the underlying factual basis is not very strong for either witness. That said, we find that Dr. Foroosh’s testimony is more logically sound and consistent with the ’840 patent disclosure. Based on our reading of the specification, we find a clear indication that “stickiness” has to do with the past. In order to control “the extent by which preceding portion(s) . . . impacts determination of the smoothed trajectory” (emphasis added), one must control the degree by which the past frames impact determination. And to control the degree of the past’s influence, one must, as a consequence, favor the past over the future. That is, the frame of reference of the stickiness parameter is the past. The specification could have used a time-agnostic term, like a “nearness” or “adjacency” parameter, but it did not. Thus, the fact that “stickiness” is used in conjunction with “preceding” indicates that it deals with a preference for preceding frames. On this basis, we find Dr. Katsaggelos’s testimony less persuasive than Dr. Foroosh’s.” slip op. at 10

      “That said, we do not construe a stickiness parameter as prohibiting consideration of future frames. Instead, we determine that the stickiness parameter’s value determines the impact of the preceding portions, versus the following portions. The ’840 patent recognizes this, when it says that a stickiness parameter value of “1,” representing a “lazy” stabilizer that maximally favors the past, would not override a violation of the margin constraint based on the look-ahead (i.e., would not allow the viewing window to fall out of bounds in the event of large future motion). See Ex. 1001, 22:26–30; see also id. at 12:61–13:29 (acknowledging that favoring the past may lead to a conflict with the viewing window determination), 15:39–60 (adjusting the viewing window to ensure it does not violate a margin constraint). Thus, while a past-favoring parameter by necessity favors the past over the future, it does not prohibit consideration of the future. In view of the above, we construe the claimed “stickiness parameter” as a parameter that controls the extent by which preceding portions of the trajectory impacts determination of the smoothed trajectory, with an understanding that in order to favor preceding portions, to some extent, the parameter must relatively disfavor following portions.” slip op. at 10

      “position and a real device position. Id. at 18:27–40. In other words, the blur is addressed by analyzing the image to identify motion and then shifting the image. Shi, however, does not disclose how its parameter is based on low light (or the long exposure times indicative of low light). In its Petition, Petitioner asserts that a person of ordinary skill in the art would understand that “blurs can be caused by low light conditions.” Pet. 28 (citing Ex. 1003 ¶ 111). Although this is true, that does not mean that Shi’s blurs are identified by a parameter that considers low light. As we just described, Shi identifies the blur by quantifying the amount of motion of the points in an image, not by identifying low light. This is simply a different way to determine the presence of motion blur. In Shi, blur is measured, whereas in the ’840 patent, it is inferred based on low-light conditions (e.g., by observing the exposure time). See, e.g., Ex. 1007, 18:7– 26; Ex. 1001, 19:12–26. In its Reply, Petitioner does not point to any further disclosures. Accordingly, we find that Shi does not disclose the “low-light” aspect of the claimed low-light high-pass parameter. This is sufficient to determine that Petitioner’s ground does not meet all claim limitations. Similarly, we find that Shi does not disclose the “high-pass” aspect of the parameter. Shi’s blur compensation uses a spherical interpolation to modify the image. Ex. 1007, 18:27–40. The low-light high-pass parameter, as we have construed the term, allows more high frequencies. To allow more high frequencies, this necessarily means either allowing fewer low frequencies, or allowing more high frequences as opposed to some counterfactual situation in which fewer high frequencies were going to be allowed. See Ex. 2020, 94:23–95:15; Ex. 2022. We are directed to no persuasive evidence from Petitioner that Shi’s spherical interpolation favors high frequencies over low frequencies. Accord Ex. 2018 ¶ 107 (Patent Owner’s expert stating that Shi’s spherical interpolation “reintroduce[es] both high- and low-frequency motion”). Even if Shi allows the viewing window to track the camera position “consistent with the natural blur in the image” (Ex. 1007, 17:63–67), we are not provided with sufficient evidence to conclude by a preponderance of the evidence that providing a similar visual goal as a high-pass parameter (Ex. 1001, 22:16–18, “the output motion may include high frequencies that mask motion blur”) is the same as having a high-pass parameter. Again, merely preserving high frequencies is not the same as having a “high-pass parameter” because, as construed, a “high-pass parameter” also involves some degree of attenuation of low frequencies or relative increase of high frequencies. Accordingly, we find that Shi does not disclose the “high-pass” aspect of the claimed low-light high-pass parameter.” slip op. at 18

Because the challenged claims of the ’414 patent have an effective filing date before the effective date of the applicable AIA amendments, we refer to the pre-AIA version of 35 U.S.C. § 103 throughout this Decision. 2 Mauer et al., U.S. Patent No. 7,395,085 B1, issued July 1, 2008 (Ex. 1005, “Mauer”). 3 Waylett et al., U.S. Patent No. 8,184,603 B2, issued May 22, 2012 (Ex. 1006, “Waylett”). computer science, electrical or computer engineering, physics, or a similar discipline . . . [and] would also have at least two years of relevant experience including, for example, work related to telecommunications networks. Pet. 3 (citing Ex. 1003 ¶ 54). The institution decision adopted Petitioner’s definition of a person having ordinary skill in the art. Dec. on Inst. 11–12. Patent Owner applied this definition for its response. Resp. 19. Petitioner’s undisputed definition of a person of ordinary skill in the art is reasonable and consistent with the prior art and ’414 patent specification.

      “a) Combination of Mauer and Waylett In support of both Ground 1 and Ground 2, Petitioner argues that a person of ordinary skill in the art would have been motivated to combine Mauer’s and Waylett’s disclosures, “using Waylett’s Network-in-a-box 224 in each of Mauer’s WWAN 14 and WLAN 12, resulting in at least two DMA systems.” Pet. 11–13. Asserting that “Mauer teaches providing sufficient network coverage by use of different kinds of networks, network interfaces, and protocols,” Petitioner contends that a person of ordinary skill in the art would have recognized that “Waylett discloses an inexpensive way to implement the same networks used in Mauer’s WWAN 14 and WLAN 12.” Id. Citing similarities in Mauer’s and Waylett’s systems, Petitioner argues that “a POSITA would have been able to modify Mauer’s WWAN 14 and WLAN 12 networks so that each network uses Waylett’s NIB 224.” Id. at 14. According to Petitioner, the combination would have included a number of beneficial features from Mauer. Id. at 14–15. Petitioner further advances three reasons that a person of ordinary skill would have had to combine the references’ teaching. Id. at 15–16. First, asserting that Waylett discloses cost benefits and Mauer discloses “an improved method and system for notifying mobile stations,” Petitioner contends the “references each provide reasoning” to combine their disclosures. Id. at 15. Second, Petitioner argues that a person of ordinary skill in the art would have been motivated to “improve Mauer’s distributed wireless network system by consolidating it into a single box, making it compact in design allowing for faster deployment.” Id. at 16. “Third, Waylett’s NIB would help mitigate the shared concern of Mauer—that is, reaching a mobile station as it roams or moves outside of the service or coverage area.” Id.” slip op. at 24

      “Petitioner does not establish that Mauer sends calls to voicemail based on the two determinations claim 1 recites. Resp. 55–56. In particular, as we explain above, claim 1 requires making use of the DPR after first determining the second mobile subscriber is not located within a first wireless coverage area based on HLR and VLR information and also determining that the second mobile subscriber is not located within a second wireless coverage area based on certain CLR information. The Petition, at best, attempts to establish that Mauer directs to voicemail when a “communication session cannot be established over the first or second wireless network.” Pet. 37. But a general determination that a “communication session cannot be established” does not teach or suggest claim 1’s specific requirements that first, the DPR is utilized in the specific circumstance that the second mobile subscriber is not located within the first wireless coverage area (with this determination being made based on HLR and VLR information), and second, that the DPR is also not located within the second wireless coverage area (with this determination being made based on CLR information).

      “III. MOTIONS Motion to Strike (Paper 50) Petitioner filed a motion to strike portions of Patent Owner’s Sur- Reply. Paper 50. Patent Owner opposes the motion. Paper 53. Petitioner contends Patent Owner raised new argument about Exhibit 1014 (a paper authored by Dr. Patterson), which was submitted with the filing of the Petition but only cited by Patent Owner for the first time in its Sur-Reply. Paper 50, 1–3; PO Sur-Reply 14 (citing Ex. 1014). According to Petitioner, Patent Owner presents new argument about the reversibility of certain crosslinks caused by formaldehyde, cites new experimental data (in Ex. 1014, Fig. 2.1), and argues such matters would have been known before any possible priority date of the ’277 patent. Paper 50, 1–3. Moreover, Petitioner argues, the untimeliness of Patent Owner’s arguments about Exhibit 1014 prevented the exhibit’s author, Dr. Patterson, from addressing them to provide explanation or context. Id. at 2–3. For the reasons given below, we deny Petitioner’s motion to strike. First, we find that Patent Owner’s arguments on Exhibit 1014 are, on balance, responsive to issues raised by Petitioner in its Reply. It is true that Petitioner submitted Exhibit 1014 with its Petition and that Patent Owner did not cite it until its Sur-Reply. However, the points raised by Patent Owner about Exhibit 1014 respond to certain of Petitioner’s arguments raised for the first time in its Reply. For example, Petitioner argued a POSA would not have been concerned about formaldehyde’s use (such as cross-linking disclosed in Heinmoller that Patent Owner cited in its Response) and that those concerns arose only after the supposed priority date of the ’277 patent. 88 Pet. Reply 8–9. Patent Owner’s citation of Exhibit 1014 is responsive on such points (e.g., it discusses cross-linking with formaldehyde’s use), it published in 2000 and is thus earlier than some references Petitioner argued were too late to evidence a POSA’s knowledge, and, lastly, it was authored by Dr. Patterson and arguably called into question the credibility of rebuttal opinions he offered about the state of a POSA’s knowledge on such issues. Second, Exhibit 1014 does not, ultimately, help Patent Owner as we do not rely on the portions of Exhibit 1014 cited by Patent Owner or Patent Owner’s argument about them. As discussed in our analysis, if cross-linking (as reported in Heinmoller or, for that matter, Exhibit 1014) was a perceived problem, Dr. Patterson provides a credible explanation how it could be and likely was addressed by Pertl.54 Supra Section II(G)(3) (citing Ex. 1047).” slip op. at 88

      “Dr. Van Ness’s proposed POSA level is too broad. Under that proposal, an individual with, for example, an undergraduate degree in microbiology and three years’ work experience studying the habitats of bacteria might qualify as a POSA. It is not clear that such a person would have sufficient, relevant experience in the detection of chromosomal abnormalities, especially through non-invasive methods for detecting fetal 10 genetic abnormalities in maternal samples, as described in the ’720 patent. See, e.g., Ex. 1001, 1:22–5:44 (Field of Invention and Background Art). Petitioner’s proposal of the POSA level is more precise because it requires familiarity with techniques for detecting cell-free DNA in biological samples, which is relevant to the prior art and the claimed technology. Petitioner’s proposal also appears to be more consistent with the cited prior art. 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).

      “Owner relied not on properties unique to EDTA, but on the fact that it was a “well-known chelator” and anticoagulant: [T]he assertion by the Office that EDTA is a cell lysis inhibitor is simply incorrect. . . EDTA is not an “agent that inhibits cell lysis.” Rather, EDTA is a well-known chelator of calcium and magnesium. EDTA is routinely added to blood during the blood collection process as an anticoagulant due to its ability to chelate calcium. Ex. 2064, 1196. Given Patent Owner’s clear intent to exclude EDTA from the scope of the claimed “agent” on the basis that it was a chelator and an anticoagulant, we find that a POSA would have understood other chelators and anticoagulants to also be excluded from the scope of the claimed agent. Consistent with this understanding, during subsequent prosecution of the application that issued as the ’720 patent, Patent Owner argued that the Holodniy reference, which disclosed a method of detecting free nucleic acid in which blood was collected in tubes containing ACD, “fail[ed] to teach or suggest a method for detecting free nucleic acid comprising, inter alia, isolating free nucleic acid from a non-cellular fraction of a sample, wherein an agent that impedes cell lysis has been added.” Ex. 1003, 1428 (emphasis added). On the salient point here, the Examiner agreed, concluding that “Holodniy et al. teach a method of detecting free nucleic acid which comprises all of the limitations of Claim 1, except these authors do not teach that their samples comprise an agent that impedes cell lysis.” Id. at 1344 (emphasis added); see also id. at 1156 (finding that Adams et al., a reference that also collects blood in tubes containing ACD, taught “all of the limitations recited in Claim 1 except these authors do not teach adding an agent that impedes cell lysis to the sample.”). And Patent Owner argues 15 persuasively, without dispute from Petitioner, that ACD is the “only” addition to the collection tubes besides the blood sample itself. Sur-reply 4 (citing Ex. 1016, 2; Ex. 2023, 20:52–54).

Patent Owner argues that the evidence as to how dextrose functions to prevent cell lysis should have been presented in the Petition. Sur-reply 16. On this record, we do not agree. While this evidence could have been included in the Petition, it is responsive to arguments raised in Patent Owner’s response. See PO Resp. 18–22. In any event, consideration of this evidence simply explains how and why dextrose has the capacity to impede cell lysis, and we have already found that the ’720 patent provides 25 evidence that dextrose has this capacity. Under the circumstances, it was therefore reasonable for Petitioner, in the Petition, to rely on such disclosures of the patent itself. Further, consideration of how and why dextrose impedes cell lysis largely benefits Patent Owner, by providing reasons why dextrose might not inhibit cell lysis under the specific circumstance present in Lee.” slip op. at 25

      “interact with and stabilize the cell membrane. Reply 3 (citing Ex. 1002 ¶¶ 22–23). In the cited testimony, Dr. Edwards states, “it was known that carbohydrates have a role in membrane stabilization” and that dextrose “is a membrane stabilizer.” Ex. 1002 ¶¶ 22–23. This is consistent with the teaching in the ’720 patent that glucose is “[a]n agent that stabilizes cell membranes.” See e.g., Ex. 1001, 6:49–56. The evidence thus supports that dextrose can help to stabilize cell membranes. However, this evidence is tempered by evidence supporting that the “impact of carbohydrates on biological membranes is extremely complex” and that it is “extremely difficult to predict how solutes such as carbohydrates will affect biological membranes.” Ex. 2231, 60:18–61:2, 83:14–18 (Dr. Edwards testimony). This is because “there’s a finite but long – long list of variables that will impact the – the mechanism by which carbohydrate interacts with the cell membrane.” Id. at 66:20–67:7; see also id. at 66:1–15 (identifying temperature, concentration and pressure as variables that play a role in how carbohydrates interact with biological membranes); id. at 68:1–17 (identifying prior and simultaneous exposure to other substances as variables that play a role in how carbohydrates interact with biological membranes). 26 Petitioner also provides evidence that dextrose helps prevent cell lysis by “maintaining osmolarity so that cells do not rupture.” Reply 3 (citing Ex. 2001 ¶ 169; Ex. 1056, 7–13, 24; Ex. 1059 ¶ 5). We agree that the cited evidence supports that dextrose has the ability to prevent cell rupture by maintaining isotonicity. In particular, Rapoport found that erythrocytes in an acid-citrate glucose solution underwent osmotic hemolysis at a slower rate than erythrocytes in a simple citrate solution. Ex. 1056, 613. However, Patent Owner introduces evidence, which we credit, that the failure to maintain isotonicity does not necessarily cause cell lysis. Ex. 2299, 237:4– 16 (Dr. Edward’s testimony). For example, cells placed in a hypertonic solution may “shrink or kind of shrivel” rather than burst, and cells placed in a hypotonic solution may swell, but will not necessarily lyse.

See, e.g., Ex. 1101, Figs. 2a, 2b, 3a, 3b, 4a, 4b, 3:22–7:44. On the other hand, we also determine that Patent Owner’s proposal is too narrow.
