    “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

    “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. Third, although we have considered Mr. Hutton’s testimony, we find it “less significant than the intrinsic record in determining the legally operative meaning of” “pre-printed lottery ticket.” Phillips, 415 F.3d at 1317. 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). In this instance, for the reasons explained above, we find that Mr. Hutton’s testimony is clearly at odds with the applicant’s arguments during prosecution and that his testimony is based on a misunderstanding of what is required by the governing caselaw for prosecution history disclaimer.” slip op. at 43

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.

    “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.

Petitioner does not explain how “control theory” and “applied mathematics” (Pet. 16) relate to the subject matter of the ’704 Patent and the asserted prior art, and Petitioner’s reference to requisite level of skill. Furthermore, whereas Petitioner requires a POSITA to have “x-ray and computing imaging experience” (id.), Patent Owner more particularly specifies “x-ray microtomography experience” (PO Resp. 5), which is the field of art for the ’704 Patent, as well as many of the asserted prior art references.

For these reasons, we apply Patent Owner’s definition of a POSITA.

    “under which “the ‘curvature of the focal plane’ must ‘track the natural curvature of the lens.’” Pet. 12. Petitioner asserts that this second “construction is the basis for Grounds 2 and 4 in [the] Petition.” Id. Petitioner’s second proposed construction repeats, word-for-word, language that appears in claim 1. Compare id. (“‘curvature of the focal plane’ must ‘track the natural curvature of the lens’”), with Ex. 1001, 12:17–18 (“curvature of the focal plane” will “track the natural curvature of the lens”). That suggests to us that Petitioner, in advancing this alternative construction, agrees with Patent Owner that those words can, and should, “be given their plain and ordinary meaning.” Resp. 19. We agree with the parties’ suggestions that those words, as they appear in the full claim limitation at hand, are clear and unambiguous. The challenged claims require multiple “layers of photodisrupted bubbles,” which “form a regular array of cells in the target region” defining “cell boundaries,” and wherein those “layers are created by scanning the pulsed laser with the optics module according to a curvature of the focal plane of the optics module to track the natural curvature of the lens.” Ex. 1001, 12:13–18 (Board’s emphasis). Where the same word, “curvature,” appears in two phrases within claim 1, namely, “curvature of the focal plane” and “curvature of the lens,” we determine that the phrases relate to one another and that the word should be assigned a single, cohesive meaning. Id. Read fairly, this limitation indicates that the layers of photodisrupted bubbles that form the cell boundaries are generated by scanning a pulsed laser according to a single curvature – a curvature that characterizes both the focal plane of the optics module and the natural bend of the lens. Id. Accordingly, on this record, we determine that the “curvature of the focal plane” itself must “track the natural curvature of the lens.” Id. Other evidence of record supports that determination. Most notably, the record of examination includes this unequivocal statement: “It was Applicant’s inventive idea to design the laser surgical system such that the curvature of its focal plane tracks the curvature of the eye.” Ex. 1002, 133.7” slip op. at 17

Dr. Bentley’s prior experience includes, for example, working on optics related to “broadband zoom lens for cancer screening, several high-resolution broadband infrared cameras,” and “a multi-photon endoscope objective,” but includes no work, on this record, that relates to optics for laser surgery of the eye.
