“We begin with “the context in which a term is used in the asserted claim,” which can be “highly instructive.” Phillips, 415 F.3d at 1314. In this case, claim 1 recites that the claimed assay is “capable of unambiguously detecting the presence or absence of each of said at least M analytes, in any combination of presence or absence, in a single sample volume, . . . wherein the analytes are amplified in the single sample 15 In this regard, we note that Petitioner’s claim construction position is not predicated on the collection of droplets being reconstituted into its original, pre-partition form prior to amplification; rather, the droplets remain compartmentalized from each other in the PCR thermal cycling tube. Tr. 65:21–66:9 (Petitioner’s counsel explaining that the droplets do not combine in the PCR thermal cycling tube but, rather, are “suspended in an immiscible fluid and analyzed en masse”). indicates that the first instance of single sample volume, i.e., the single sample volume in which the presence or absence of each M analytes are to be detected, is the antecedent basis for the second instance of “single sample volume,” i.e., the single sample volume in which the analytes are amplified. Thus, as the parties appear to agree, the single sample volume in which amplification takes places must be the same single sample volume in which the presence or absence of analytes are to be detected. We are not persuaded that, when accorded its plain and ordinary meaning, a single sample volume divided into a collection of droplets would be considered the “same” single sample volume prior to its partition.” slip op. at 17

“With respect to the limitation, “wherein the analytes are amplified in the single sample volume,” Petitioner asserts that “Larson discloses PCR assays that amplify target polynucleotide in a single sample volume, specifically a portion of the reaction mixture that is subsequently partitioned into droplets.” Pet. 31 (emphasis added). There is no dispute that the amplification of the analytes in Larson occurs in the droplets. Larson ¶¶ 6–7 (explaining that “[d]igital PCR (dPCR) is an alternative quantitation method in which dilute sample are divided into many separate reactions” and that “[t]he template is amplified in the droplet for detection”) (emphasis added). Because the claims require that amplification of the analytes be in the same sample volume in which the at least M analytes, in any combination of presence or absence, is unambiguously detected, and because the pre-partition single sample volume is not the same single sample volume as the collection of droplets after partition under our claim construction set forth above, we find Petitioner has not shown, by a preponderance of evidence, that claims 1–10 and 13–19 are anticipated by Larson.17 Tr. 68:12–69:14 (Petitioner’s counsel” slip op. at 27

“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.

“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

“Given the teachings of the specification, we agree with Patent Owner that a low-light high-pass parameter is a parameter of a smoothing function that favors high frequencies (high pass) when exposure times are long (low light). See Tr. 42:10–18 (Patent Owner’s counsel stating that “high-pass” means “there’s a bias or preference for high frequencies”); Ex. 2020, 93:23– 94:15 (Petitioner’s declarant, Dr. Katsaggelos, agreeing that a high-pass system attenuates the low frequency of a signal). Although we acknowledge Petitioner’s position that the specification provides other ways or considerations in implementing a smoothing function, based on our above analysis of the specification, we find that the specification describes the lowlight high-pass parameter as a specific component of a smoothing function. See, e.g., Ex. 1001, 21:17–25 (setting out several parameters besides the low-light high-pass parameter used in trajectory smoothing).” 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

“We do not find Mr. Hutton’s testimony particularly helpful. First, we have addressed the points raised by his testimony in our discussion above because they are largely the same as the arguments raised in Petitioner’s Reply. Second, we find his testimony entitled to very little weight because he applies an incorrect understanding of the caselaw, which mirrors Petitioner’s incorrect and arguably misleading quotations of the Federal Circuit’s decision in Quest. In particular, in paragraph 5, Mr. Hutton states the following as his understanding of the law as it applies to prosecution disclaimer: “I also understand that in order to disclaim embodiments within the specification, the statements should have some indication that the applicant intended to surrender embodiments from the specification.” Ex. 1038 ¶ 5 (emphasis added). This then leads Mr. Hutton to state: “[t]hus, in my opinion, a [person of ordinary skill in the art] would not view applicant’s statements as a disclaimer, because the applicant never stated that they intended to surrender multiple embodiments described in the specification.” Id. ¶ 13 (emphasis added). As we explained above in responding to a similar argument by Petitioner, the caselaw does not require an applicant to expressly state whether a disclaimer excludes particular embodiments of the subject specification when disclaiming claim scope during prosecution. See Quest, 924 F.3d at 1229. And, as noted above, counsel for Petitioner agreed that such a statement explicitly disclaiming particular embodiments is not required. Tr. 12:18–13:17.

In particular, we are cognizant of the Federal Circuit’s guidance that we “should discount any expert testimony that is clearly at odds with the claim construction mandated by . . . the prosecution history.” Id. at 1318 (internal quotation omitted).

“II. ANALYSIS A. LEVEL OF ORDINARY SKILL Petitioner defines the person of ordinary skill in the art as follows: As of February 2006, a person of ordinary skill in the art (“POSITA”) would have been a person with a degree in 1 The Leahy-Smith America Invents Act, Pub. L. No. 112-29, 125 Stat. 284 (2011) (“AIA”), amended 35 U.S.C. § 103. 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. Based on the record before us, we adopt Petitioner’s undisputed proposal. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art may reflect an appropriate level of skill in the art).” slip op. at 12

“Petitioner does not submit constructions for any claim terms. According to Petitioner, “[t]he Board construes claims under the same standard used in civil actions in federal district court. The district court for the related litigation has not yet construed the claim terms.” Pet. 7. The parties provided briefing regarding construction of “distributed mobile architecture (DMA).” Resp. 19–34; Pet. Reply 1–3; PO Sur-reply 11–14. But we do not need to construe “distributed mobile architecture (DMA)” to resolve this inter partes review. We thus do not construe this claim term. We also do not discern a need to construe explicitly any other 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. 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. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). We discuss the meaning of ’414 patent claims to the extent necessary to resolve the issues we address below. Id.” slip op. at 14

“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). See PO Sur-Reply 8–9; Ex. 2001 ¶¶ 111–113. For the reasons above, Petitioner does not establish by a preponderance of the evidence that the combined art teaches or suggests the final “when” recitation of claim 1.” slip op. at 29

“Based on the information above, we conclude that the limitation “a groove that is laterally offset from the chamfered mandrel” requires the groove to be entirely to the side of any part of the mandrel. This construction is consistent with the words of the claim—the claim states that the groove is laterally offset from, or to the side of, the chamfered mandrel, not merely offset from a portion of or the centerline of the mandrel. This construction is also consistent with the one embodiment describing the relationship between the mandrel and groove containing the seal, which depicts the groove entirely to the side of the chamfered mandrel. We do not accept Mr. Jobin’s testimony that laterally offset is determined relative to the centerline of an object. Neither the intrinsic record nor other extrinsic evidence provides support for Mr. Jobin identifying the centerline of an object as the reference point for determining if a point is laterally offset from the object.” slip op. at 31

“We do not agree with Petitioner that Yoakim teaches a groove that is laterally offset from the chamfered mandrel. As we indicated in our claim construction section, we construe the claim term to require the groove to be entirely to the side of any part of the mandrel. We agree with Patent Owner that, as depicted in Yoakim’s Figure 35, the alleged groove is not entirely to the side of any part of the mandrel. See Pet. 69; see also Pet. Reply 19 (showing the alleged groove, in red, including a portion over the chamfered mandrel); PO Resp. 55 (same). Even if Petitioner’s position is that all of the groove must be to the side of the centerline of the mandrel, Petitioner fails to prove that Yoakim teaches such a structure. As seen in Petitioner’s illustration at page 19 of Petitioner’s Reply (reproduced above), a small portion of the groove (which Petition colorizes in red) is to the left of the centerline (shown in green).

“We determine Patent Owner’s reading of the claim limitation is the better one. The limitation begins with the verb “locating,” and it therefore makes sense that the clause would recite what is located (i.e., encryption information) and where it is located (i.e., within the requested portions of the selected stream of protected video). In other words, it is reasonable that the second and third clauses of the limitation both modify the first clause (for example, as could perhaps be expressed through the use of commas as “locating encryption information, that identifies encrypted portions of frames of video, within the requested portions of the selected stream of protected video”).10 On the other hand, Petitioner’s reading of the limitation, 10 In general, we recognize that the use of commas to set off phrases in claim drafting is not consistent. We included commas above to illustrate Patent Owner’s understanding of the claim limitation. allowing only the second clause to modify the first, while not unreasonable, makes less sense. That is, the encrypted information identifies the encrypted portions of frames, which in turn are within the requested portions of the selected stream of protected video. Reading the claim in its entirety, the encrypted portions of frames would be understood to be located within the requested portions of the stream; it does not seem necessary for the claim to expressly recite that aspect. For example, the very next limitation— limitation [m] of claim 1—refers to “each encrypted portion of the frames of video” but does not expressly recite “within the requested portions of the selected stream.” Ex. 1001, 27:58–60. Thus, when limitation [l] recites “within the requested portions of the selected stream,” it seems more likely that the clause refers to where that encrypted information is located rather than simply to indicate the obvious location of the encrypted portion of the frames of video. We therefore view Patent Owner’s reading of the claim language as the better one.” slip op. at 13

“I am persuaded that the Petition demonstrates that one of ordinary skill in the art would have had a motivation to combine Chen, Lindahl, and Hurst, as asserted by Petitioner. As the Federal Circuit found, the Petition pointed to and relied upon the portions in Chen describing pre-Chen art, without scalability or FEC features that were part of what Chen describes as aspects of its own inventive system. Netflix, slip op. at 9–10 (citing Pet. 17– 19, 69–70).

I determine that Chen-924 provides support for the rationale provided in the Petition, and that one of ordinary skill in the art would have been motivated to combine Chen and Lindahl in view of the disclosure of Chen-924. As discussed above, the Petition does not rely solely on privacy concerns and improvements to efficiency as its motivation to combine the references.

“I agree with Petitioner that Patent Owner’s Remand Brief, specifically pages 1–7, attempt to address aspects of claim 1 for the first time on remand. I also agree that Patent Owner’s arguments attempt to recharacterize limitations [j] and [k] to raise issues that Patent Owner did not raise previously, in contravention of our Order that issues raised needed support from “where those issues were raised in previous briefings by the parties.” Paper 56, 2. I have addressed whether scalability and FEC are integral to how Chen operates above, as well as whether the Petition relies on those aspects, supra. The questions about how Chen operates and what portions of Chen are asserted in the ground of unpatentability were previously raised, but now are being considered or reconsidered, based on the Federal Circuit’s decision. In Patent Owner’s Remand Brief, pages 1–7, the citations to argument previously raised do not support the arguments now presented by Patent Owner on remand. As such, I determine Patent Owner’s new arguments fall outside the scope of remand, and I dismiss these arguments seeking to distinguish limitations [j] and [k] from the cited prior art combination.24” slip op. at 62

“7 Patent Owner’s Brief on Remand recognizes that there are two arguments Patent Owner raised in its Patent Owner Response that were not addressed in the Final Written Decision. See PO Remand Br. 1 (citing PO Resp. 24–37 (the construction of “locating encrypted information . . . within requested portions”), 38–58 (referring to Patent Owner’s “common keys” argument)). 8 The Final Decision also addressed Petitioner’s Motion to Exclude (Paper 42). See Final Dec. 28–37 (granting-in-part, denying-in-part, and dismissing-in-part Petitioner’s Motion). Our determinations on that Motion were part of Petitioner’s appeal to the Federal Circuit. See Paper 52. Because the Federal Circuit did not address this aspect of the Final Written Decision and the Federal Circuit’s decision does not impact our previous rulings on the Motion, we maintain those rulings here. Additionally, on remand, Petitioner requested authorization to file a motion for sanctions, which we held in abeyance until the parties’ briefing on remand was complete. See Ex. 3003, 1. Petitioner requests sanctions because of the impropriety of Patent Owner’s remand brief, including new claim construction arguments for limitations [1j] and [1k], and prejudice to Petitioner. Id. at 3, 5. Although we reserved further consideration of Petitioner’s request, we expanded both the time and pages allowed for Petitioner’s responsive brief, and also allowed Petitioner to address any related issues in its responsive brief.

“B. Conflicting Opinion Testimony Petitioner’s own witness, Dr. Giacomin, opines that an ordinarily skilled artisan “would have been familiar with various machines and methods that would have enabled the thermoforming of multilayer dental sheets into shapes that conform with the teeth (i.e., creating a dental appliance).” Ex. 1002 ¶ 25. Nonetheless, Petitioner does not contest Patent Owner’s evidence that Dr. Giacomin himself lacks that qualification. Compare Resp. 9–10 (citing Ex. 1002 ¶¶ 1–9, 17 & n.1), with Reply (nowhere contesting that evidence). Petitioner also leaves uncontested Patent Owner’s evidence that Dr. Osswald, by contrast, possesses “the required experience” with dental appliances, including thermoforming processes for their manufacture. Compare Resp. 10 (citing Ex. 2006 ¶¶ 2–8; Ex. 2007), with Reply (nowhere contesting that evidence). Dr. Giacomin possesses excellent qualifications in the field of polymer rheology, but on this record, he demonstrates no, or inadequate, familiarity or experience with methods of thermoforming dental appliances from polymeric materials, which by his own admission is a minimum qualification of the hypothetical person of ordinary skill in the art. Ex. 1002 ¶¶ 1–11 (statement of qualifications), App’x A (curriculum vitae). Patent Owner’s witness, Dr. Osswald, by contrast, has “experience with polymer materials used in dental appliances” and “shaping operations, including thermoforming” processes for such applications. Ex. 2006 ¶¶ 5, 6. Against that backdrop, where the two witnesses’ opinions differ about the level of ordinarily skill in the art of thermoforming processes for dental appliances at the time of the invention, we credit Dr. Osswald’s opinions over those of Dr. Giacomin. We take note, moreover, that Dr. Osswald’s opinions would not change under Petitioner’s somewhat different definition of the level of ordinary skill in the art. Ex. 2006 ¶ 14.” slip op. at 11

“In the absence of explanation by Petitioner, we are left to wonder why either of those two ranges reported in Sun would have been recognized as applicable, without modification, to the three-layer dental splint of Hinz. Starting with a commercially-available, two-layer sheet of hard-soft PC-TPU or hard-soft PETG-TPU thermoplastic polymers, Hinz bonds a third layer, consisting of hard PC or hard PETG, to the soft TPU layer of the two-layer material by a process of thermoforming. No prior art reference explains how that process would have been understood to affect the overall flexural modulus of the resulting three-layer, hard-soft-hard composition. Petitioner does not supply an adequate reason for combining Sun’s preferred flexural modulus range, reported for Sun’s dental appliances at a temperature of 23˚ C, to dental splints formed by Hinz from fundamentally different polymers and a fundamentally different process. See Pet. 65–68 (entirety of four-page analysis on this ground); Resp. 32–38; Sur-reply 7–14 (well-supported explanation of those fundamental differences); Reply 8–16 (Petitioner’s unpersuasive responsive positions). The flexural modulus of Sun’s dental appliance not only is temperature dependent but also varies with the flexural strength of the polymeric material at hand. Ex. 1018 ¶ 12. Too late in the Reply, Petitioner raises fact-intensive reasons why those differences would not have mattered to an ordinarily skilled artisan. Reply 8–16. In any event, we agree with Patent Owner that Petitioner glosses over “[f]undamental differences” between the polymers and processes of Sun and Hinz, differences that “are central to [the] motivation to combine inquiry” and undercut Petitioner’s view that an ordinarily skilled artisan would have understood either of Sun’s flexural modulus ranges to apply, without modification, to Hinz’s polymers and process.
