      “We note that “act upon” is not defined in the Specification of the ’575 patent. “Act upon” appears for the first time in claim 1 of the ’575 patent. The Specification describes that “the cage assembly may comprise an expander such as an expansion screw or a shim which, when inserted, selectively expands the body of the cage assembly to a desired size.” Ex. 1001, 4:26–29. The Specification further describes that “translation of the elongate expander proximally toward the trailing end expands the cage body by separating the at least a portion of the upper portion from at least a portion of the lower portion.” Id. at 6:56–59. (emphasis added). We determine that “expander expands the cage” is construed in light of the Specification to mean that the expander acts upon both the upper and lower portion of the cage to move the upper and lower portions further apart. We note, however, there is no requirement that each portion is moved away from the longitudinal expander by the same amount.” slip op. at 13

      “The Specification does not define “unobstructed” or “obstructed.” Based on the disclosure in the Specification, the prosecution history, 7 and the annotated Figure 5A and 5B above, the term “unobstructed” is understood to mean that there are no obstacles or structures lying in the path of the window created by the upper portion, lower portion, and elongate expander that would impede the view through the window. Figure 5B does not show any features that impede the view through the aligned window and thereby shows an “unobstructed view.” Tr. 40:20–41:11, see id. 41:5–6 (“Figure 5B shows nothing extending into the window, and that’s the only 7 Petitioner explains that “the plain meaning of an ‘open’ window is well understood to be a state allowing passage through the window.” Pet. 21 (citing Ex. 1003 ¶ 63). According to Petitioner, Patent Owner expressly defined “unobstructed” during prosecution to “mean there are no features lying in the path and blocking the window.” Id. at 21–22. Patent Owner acknowledges that the term “unobstructed” was added during prosecution in order to distinguish over Baynham (US 2007/0270968 Al, published Nov. 22, 2007).

There’s no[] qualifying language in the specification that would allow a retreat to specify a particular amount that was considered acceptable.”) support that there is.”). Unobstructed does not refer to the entirety of each window, but rather where they overlap relative to one another.

      “XI. CONCLUSION Petitioner has, at this stage, established a reasonable likelihood of prevailing in showing that at least one of the challenged claims is unpatentable. This determination is, however, based on a preliminary record and is not final on any issues of patentability. We will make a final determination on the patentability of the challenged claims, as necessary and applying the preponderance of the evidence standard, based on a fully developed record through trial. XII. ORDER In consideration of the foregoing, it is hereby: ORDERED that, pursuant to 35 U.S.C. § 314(a) an inter partes review of claim 59 of the ’802 patent is hereby instituted on the grounds set forth in the Petition, commencing on the entry date of this Order, and pursuant to 35 U.S.C. § 314(c) and 37 C.F.R. § 42.4, notice is hereby given of the institution of a trial.” slip op. at 34

      “Determining whether claims are anticipated involves a two-step analysis. The first step involves construction of the claims of the patent at issue. Claim construction is a question of law reviewed de novo.” In re Aoyama, 656 F.3d 1293, 1296 (Fed.Cir.2011). “The second step [of an anticipation analysis] involves comparing the claims to the prior art. Anticipation is a question of fact reviewed for substantial evidence.” In re Aoyama, 656 F.3d at 1296. “A prior art reference anticipates a patent claim under 35 U.S.C. § 102(b) if it discloses every claim limitation.” In re Montgomery, 677 F.3d 1375, 1379 (Fed. Cir. 2012). A reference may anticipate inherently if a claim limitation that is not expressly disclosed “is necessarily present, or inherent, in the single anticipating reference.” Verizon Servs. Corp. v. Cox Fibernet Va., Inc., 602 F.3d 1325, 1337 (Fed. Cir. 2010).

      “limitation of claim 24 as Patent Owner characterizes it. First, this phrase is in the preamble prior to the word “comprising,” and does not, in our opinion, provide antecedent basis for any subsequent limitations in the body of the claim. See Eaton Corp. v. Rockwell Int’l Corp., 323 F.3d 1332, 1339 (Fed. Cir. 2003) (“[w]hen limitations in the body of the claim rely upon and derive antecedent basis from the preamble, then the preamble may act as a necessary component of the claimed invention.”). Second, the phrase plainly reads as a desired result or effect of “selecting said first twist multiplier to be at least about 1.5 times said second twist multiplier,” which is the last step recited in the body of claim 24. Ex. 1001, 14:1–2. See Poly-Am., L.P. v. GSE Lining Tech., Inc., 383 F.3d 1303, 1310 (Fed. Cir. 2004) (The Federal Circuit explaining that “a preamble is not limiting where a patentee defines a structurally complete invention in the claim body and uses the preamble only to state a purpose or intended use for the invention.”) (citations omitted). Notably, neither “flex fatigue” nor “improved flex fatigue” are mentioned in the specifically recited steps of the claimed method. Ex. 1001, 13:13–14:2. Third, Patent Owner mainly asserts that this phrase “is a fundamental characteristic of the claim and consequently, is a limitation of claim 24.” PO Resp. 7–7. Such a desired result, improving flex fatigue, as it is recited in claim 24, in our view, does not explain satisfactorily why this phrase in “the preamble is necessary to give life, meaning, and vitality” to the claimed method. Pitney Bowes, Inc. v. Hewlett-Packard Co., 182 F.3d 1298, 1306 (Fed. Cir. 1999). Accordingly, we are not persuaded that this phrase is a limitation.” slip op. at 9

      “would have been motivated to use the disclosed 9.65 TPI first twist rate with the specific example’s 2.82 TPI second twist rate because using the 9.65 first twist rate would be a simple substitution of the specific example’s first twist rate with another first twist rate that was also disclosed in the same patent.” Id. ¶ 68. We are persuaded by Dr. Adanur’s testimony in this case. The motivation to interpolate values in disclosed ranges, such as those in Hasaka, is well-settled in our case law. See In re Malagari, 499 F.2d 1297, 1303, 182 USPQ 549, 553 (CCPA 1974) (claimed invention is rendered prima facie obvious by the teachings of a prior art reference that discloses a range that touches the range recited in the claim). Using the values provided by Dr. Adanur which are taken directly from Hasaka’s disclosure, a TM ratio of 1.97 is obtained which falls directly within the range recited in claim 9. Where a claimed range falls within a range disclosed in the prior art, a presumption of obviousness applies. See Iron Grip Barbell Co., Inc. v. USA Sports, Inc., 392 F.3d 1317, 1322 (Fed Cir. 2004) (rehearing denied). To the extent Patent Owner argues that the first twist multiplier is not a result-effective variable, we disagree. PO Resp. 4. It is reasonably clear from Kovac that a person of ordinary skill in the art would have understood that increasing the twist rate of the yarn results in an increase in flex fatigue resistance while decreasing tensile strength of the yarn. Ex. 1007, 4:15–46. Kovac’s disclosure, and Dr. Adanur’s reliance on it to support his testimony as to the knowledge of a person or ordinary skill in the art, is confirmed by Patent Owner’s declarant, Dr. Wu, who testified that “[i]t also was my understanding at the time that the prior art disclosed that both an increase in either the first or second twist resulted in a higher flexural fatigue resistance.” Wu declaration ¶ 7; see also In re Applied Materials, Inc., 692 property is affected by the variable is sufficient to find the variable result-effective.”). We find the evidence and testimony of the declarants for both parties persuasive that a person of ordinary skill in the art understood that increasing the first or second twist rate resulted in a corresponding increase in the respective first and second TMs and a higher flex fatigue resistance which are therefore result-effective variables. Overall, we are persuaded by Petitioner’s optimization argument, becuase the discovery of an optimum value of a result effective variable is ordinarily within the skill of the art, and thus usually obvious.

      “for the yarn from of 17 to 38 per 10 cm, and range of the second twist rate (in the opposite direction) for the cord that is 10 to 23 per 10 cm. Ex. 1004, 6:47–48. Dr. Adanur has testified that Hasaka’s disclosed cord twist rates result ultimately in a specific range of TPIs, and hence TMs, given that the denier is constant across both the first and second TM’s, and that a person of ordinary skill in the art “would have been motivated to find the optimal TPI values for the first and second twists that, when combined, produces the optimal cord.” Adanur I ¶ 66. Given the finite ranges disclosed by Hasaka, Dr. Adanur testifies that a person of ordinary skill in the art “would have tried the various first twist TPI values on the disclosed two-1,000 denier strand with a reasonable expectation of success because the materials, configuration of yarn, and the twist rate, would all be easily achieved using standard equipment and materials at the time.” Id. ¶ 67. Dr. Adanur testifies that given Kovac’s disclosure relating to the level of knowledge and skill in the art, i.e., that increasing the twist rate of yarn, i.e. the first twist rate, results in increasing fatigue resistance, up to a point, a person of ordinary skill in the art “would have considered it obvious to try the finite number of disclosed first twist rate TPI values, including the disclosed 9.65 TPI value, to obtain a cord with a first-to-second TM ratio of 1.97.” Id. Pointing to the Background section of the ’934 Dr. Adanur testifies that “there was a market pressure and design need for designing belts and load carrying cords with improved flexural fatigue.” See id. (citing Ex. 1001, 1:46–49 (“The need remains for a high modulus load carrying cord, including for incorporation in an endless belt or similar rubber composite article, which exhibits a good balance of load carrying capability and flexural fatigue resistance.”)). “would have been motivated to use the disclosed 9.65 TPI first twist rate with the specific example’s 2.82 TPI second twist rate because using the 9.65 first twist rate would be a simple substitution of the specific example’s first twist rate with another first twist rate that was also disclosed in the same patent.” Id. ¶ 68.

      “focused split sample typically would not allow two cells to arrive at the inspection region at once, because there is not enough space for two 10-μm cells to travel side by side.” See Ex. 1054 ¶ 21 (citing Ex. 1005, 5662) (emphasis added). The qualifier “typically” for two cells not arriving at the same time does not indicate that there would be no split stream. And Dr. Issadore seems to concede there could be a split sample. Id. Further, Dr. Issadore does not state which dimensions of which of Simonnet’s channels that he is using as a reference.27 We determine that Dr. Issadore provides insufficient evidence and reasoning for an understanding that there would be a single stream if mammalian cells were used, in addition to making a statement that stops short of that conclusion. Although not argued by Petitioner nor discussed by Dr. Issadore, Simonnet does state: “we expect the HTD to be compatible with cells up to ~15 µm in size.” Ex. 1005, 5662. Simonnet also states: “We expect that with the improvements in optics and detection electronics, a cytometry system based on the HTD would match the throughput, sensitivity, and accuracy of commercial flow cytometers and would be an adequate tool for assaying fluorescently marked live cells.” Id. These statements can be fairly read as a statement of reasonable expectation of success of using mammalian cells in the device. However, Simonnet is silent as to whether the mammalian cells would be in a single stream, and if anything, Simonnet appears to be inviting further experimentation. Accordingly, Petitioner has not provided adequate reasoning to modify Simonnet to form a single sample stream.” slip op. at 52

      “sheath flow does not mean that “focusing” requires sheath flow. In other words, the Specification does not contain a definition of “focusing” that defines “focusing” as requiring “sheath flow.” As discussed above, the Specification does state “focusing (e.g., constricting).” See also Tr. 41:22– 42:8 (discussing the Specification of the ’439 patent). Whether or not this disclosure rises to the level of a definition, it indicates that focusing is understood to be constricting and does not mention “sheath flow.” Although sheath flow may, in certain cases, be a natural result of having multiple fluid focusing features (see Ex. 1001, 14:6), the claim itself does not require that focusing include sheath flow.11 11 In terms of resolving the dispute between the parties, the real question appears to be whether the sample stream that exits the focusing region must be a single sample stream or whether it may encompass split sample streams, a question that we address in the next subsection. Patent Owner’s ultimate argument appears to be that “focusing” requires a single sample stream because “focusing” requires sheath flow and sheath flow requires a single sample stream. However, we agree with Petitioner that persons of ordinary skill could still refer to split streams as having “sheath flow” (see Ex. 1054 ¶ 11; Ex. 1043, 2215, Fig. 10 and caption (“separated two-sample 3D sheath flow”); Ex. 1044, 2 (“multiple core-sheath flow”), and therefore, even if we agreed with Patent Owner that focusing requires sheath flow, that would not clarify whether “focusing” precludes split sample streams. In any event, we conclude that focusing does not require sheath flow. We recognize that there are examples in the Specification where there is sheath flow. E.g., Ex. 1001, 5:30–32 (“Certain embodiments described herein relate [to] systems and methods for producing a sheath flow . . .”), 10:35–37 (“The illustrated core stream forming geometry 400 provides improved sheath flow capabilities and thus improved sample focusing capabilities.”). However, case law generally counsels against importing limitations from the Specification into the claims. See, e.g., Phillips v.

      “the present Petition, may have gained a tactical advantage by being able to review the patent owner response in IPR2021-00342. However, based on the present record, it appears that the principal reason behind Petitioner’s delay was to wait until Patent Owner identified the claims at issue in the District Court Litigation, rather than filing serial petitions to test theories in an initial petition and adapt accordingly in a later petition. Further, Petitioner had the patent owner response in hand for only a few weeks (September 30 to October 13) before filing the present Petition.

      “Reasons Supporting Obviousness Over Quintana We find for the reasons provided below that Petitioner has shown by a preponderance of the evidence persuasive reasons the subject matter of the Challenged Claims, as a whole, was taught by Quintana, in light of the knowledge of a person of ordinary skill in the art. We further find that, to the extent a feature of Quintana relied upon by Petitioner would have required modification to correspond to a feature of a Challenged Claim, Petitioner has shown by a preponderance of the evidence a person of ordinary skill not only could have made the modification, but would have had reason to do so in light of the knowledge of a person of ordinary skill in the art. Patent Owner argues a lack of motivation to modify Quintana “to create first and second spaced-apart cutting edges.” Resp. 31–32. As explained above, we find Quintana discloses this feature without modification. See supra Section II.E.1. Patent Owner also broadly argues no motivation for any of the proposed modifications because Quintana “never describes creating and removing a strip of [trabecular meshwork],” and that Petitioner does not show how the asserted modification “would have been advantageous” and are “the product of speculation, conjecture and hindsight.” Resp 33–34. As explained above, we find Quintana discloses cutting a strip of trabecular meshwork and Patent Owner’s argument fails to address the reasons Petitioner identifies for each proposed modification. See supra Section II.E.1. We likewise find no persuasive evidence to support Patent Owner’s undeveloped arguments that any modification proposed by Petitioner of Quintana based on the knowledge in the art would have rendered Quintana’s device “unfit for its intended purpose” or that Quintana “would have taught away . . . for fear of reducing the effectiveness of the device.” Resp. 33–34. We find persuasive Petitioner’s argument in its Reply that Patent Owner “fails to explain how modifying Quintana’s needle as proposed by [Petitioner] would have increased the risk of injury to [Schlemm’s Canal], and no disclosure in Quintana that criticizes, discredits, or discourages “investigation into the modifications proposed by [Petitioner].

      “At the outset, we find that the plain language of clauses 1[i], 12[k], and 18[e], in isolation, requires only that the displayed image of one lead is aligned with the displayed image of the other lead without requiring any “repositioning” of previously displayed images. However, Patent Owner argues that other language recited in each independent claim requires first “establishing” the positions of the first and second leads, which necessarily means that “aligning” the images of the first and second leads refers to repositioning them on the display. Sur-reply 2–3. However, Patent Owner’s argument fails to recognize the distinction between establishing the physical “position” of the leads relative to a physical frame of reference and aligning computer-based images of those leads. For example, clauses 18[b] and 18[c] of independent claim 18 recite: “[b] establishing a first positional relationship between a location of a first signal delivery device and an anatomical feature of a patient” and “[c] establishing a second positional relationship between a location of a second signal delivery device and at least one of the location of the first signal delivery device or the anatomical feature of the patient.” Ex. 1001, 40:34–41. None of clauses 18[b] or 18[c] or the substantively identical clauses 1[d], 1[f], 12[h], 12[i]5 from the other independent claims mentions displaying an image of either lead on a computer screen. Rather, these clauses encompass establishing the spatial position of each of the first and second physical leads relative to a physical frame of reference (e.g., an anatomical feature of a patient or another lead). These limitations may be met without displaying leads on a computer screen at all. Accordingly, we reject Patent Owner’s argument that the claims first require positioning images of the leads on a display before aligning those images on the display.
