    “consider “whether the petitioner has demonstrated that the Office erred in a manner material to the patentability of challenged claims.” Advanced Bionics, 8. We focus our analysis on Ducharme, one of the primary references asserted in the Petition. Although Ducharme was “not before the Office during examination of the [’]895 Patent,” Patent Owner asserts that it is cumulative to a reference that “was presented to the Office during examination by IDS.” Prelim. Resp. 42–43. Patent Owner does not point to, and we have not found, any evidence showing discussion or application of the previously presented reference by the Examiner during prosecution of the ’895 patent or its related patents. In other words, “the record of the Office’s previous consideration of the art is not well developed or silent.” Advanced Bionics, 10. In such situations, “a petitioner may show the Office erred by overlooking something persuasive.” Id.; see also id. at 8 n.9 (“An example of a material error may include misapprehending or overlooking specific teachings of the relevant prior art where those teachings impact patentability of the challenged claims.”). On this record, Petitioner has shown sufficiently that the Examiner overlooked Ducharme’s teachings of the limitations that were the basis for allowing the challenged claims. Indeed, the Examiner allowed the challenged claims, stating that the closest prior art references lack the teachings of the emitted light being suitable for the commercial image recording when the emitted light is simultaneously at least 1000 lumens when either the first or the second LEDs are lit, is broad-spectrum white light having a color deviation corresponding to less than 5 points of both green and magenta of color compensation, and has a color rendering index of light emitted from each of the first or the second LEDs (whichever is lit) that is greater than 90. Ex. 1002, 150. Petitioner’s evidence indicates that Ducharme teaches an LED light suitable for commercial image recording that includes a plurality of first white LEDs having a first spectrum and a plurality of second white LEDs having a second spectrum. See, e.g., Ex. 1005, 4:1–7. Petitioner’s evidence also indicates that a person of ordinary skill in the art would have had reason to select first white LEDs with a daylight spectrum and second white LEDs with a tungsten spectrum. See, e.g., Ex. 1003 ¶ 449; Ex. 1006 ¶ 53. Further, Petitioner’s evidence indicates that LEDs satisfying the light quality parameters recited in the challenged claims were known to those of ordinary skill in the art.

At best, Petitioner presents an “obvious to try rationale”: In addition to the reasons mentioned above, a POSITA would have found it obvious to try a mapping scheme in which entries in the look-up table as taught by Taraschuk are selected such that successively decreasing inputs correspond to digital output entries with either decreasing, increasing, or similar deltas between their values. . . . Doing so would have involved choosing from a finite number of identified, predictable solutions, with a reasonable expectation of success. In that regard, the deltas between values of the corresponding digital outputs can either increase, decrease, or stay the same. Accordingly, there are only three possible relationships between deltas of successive digital outputs. With so few possibilities, a POSITA would have found it obvious to try each of them.

    “We agree with Patent Owner’s argument that the portions of Taraschuk in column 7, lines 61–67 and column 8, lines 13–15 cited by Petitioner in its challenge to claim 13 teach “an end-to-end approach” “because that calculation involves predistortion of the input M-bit word by subtracting a digitized analog sample of the ultimate output,” and as such, teach “[a]n approach that necessarily does one combined correction for all of the nonlinearities that occur in-between those ends—whether bit mismatches in the digital logic or non-linearities in the Mach-Zehnder modulator.” PO Sur-reply 18 (citing PO Resp. 30–36; Ex. 2018 ¶¶ 48, 49, 85–87, 89, 103; Ex. 1006, 7:34–39, 7:61–67). We further agree with Patent Owner’s assertion that [Patent Owner] and Prof. Dallesasse are not suggesting that Dr. Blumenthal should model the logic-level mismatches. But rather pointing out that calculating an idealized sinusoidal response in isolation is not obvious (or flowing naturally) from a reference that can only deal with compensating the combined response of the modulator and digital logic mismatches together—via real-time pre-distortion fed back from the ultimate output and subtracted from the input. Dallesasse testifies that Dr. Blumenthal starts with the premise that all that is required is deriving a complementary function to the sinusoidal response. . . . But this ignores that the disclosure of Taraschuk describes compensating “the sinusoidal response of the modulator” and “logic level mismatches through the D/A converter” together. . . . Dr. Blumenthal’s complementary sinusoidal correction curve won’t do that. The combined non-linearity from the multiple sources likely won’t simply be evenly sinusoidal. Taraschuk does not disclose, or in my opinion render obvious, any pre-calculation solution. (Taraschuk mentions a real-time analog feedback loop to pre-distort, which would not involve pre-calculation.) And it certainly does not suggest one that could deal with the combined and likely complex non-linearities described.” slip op. at 28

Id. at 6. Following our Preliminary Guidance, the parties submitted further arguments concerning the term “for a pharmaceutical composition.” Patent Owner argues the term requires that the claimed process provide STS that is sufficiently pure for use in a pediatric patient (see RMTA 8–11) and that the word “drug” in the ’363 patent’s definition of “pharmaceutical composition” requires that the anhydrous STS is of sufficient purity for pharmaceutical use. Reply RMTA 3. Petitioner argues that the construction set forth in our Preliminary Guidance was correct. See Sur-reply RMTA 2–3.

    “determine the evidence relied on by Petitioner does not support Petitioner’s position that a person of ordinary skill in the art would have been motivated to combine Levenson, Sherman, Edwards, and USP. Petitioner’s contention that it would have been obvious to a person of ordinary skill in the art to combine the teachings of Levenson with Sherman is based on Dr. Rogers’s testimony that “[b]oth references disclose synthesis of sodium thiosulfate pentahydrate.” Ex. 1008 ¶ 151; see Pet. 36, 38. Dr. Rogers further testified it would have been obvious to add Edwards’s dehydrating step to the preparation of STS pentahydrate “which is obtained following the teachings of Levenson and Sherman” because “Edwards itself discloses dehydrating [STS] pentahydrate.” Id. ¶ 154. The Petition included these arguments even though they were inconsistent with Petitioner’s previous statement, during the Sherman prosecution, that Levenson taught STS heptahydrate, and therefore “does not provide any teaching with respect to [STS] pentahydrate.” Ex. 2013, 97. This prior inconsistent statement undercuts Petitioner’s rationale for combining Levenson, Sherman, and Edwards in this proceeding. Moreover, Petitioner’s rationale for combining the references in this proceeding is inconsistent with its statements about Levenson during the Sherman prosecution. Recognizing this inconsistency, Petitioner now takes the position that the Petition and Dr. Rogers’s testimony were incorrect. Paper 32; see Tr. 21:14–22:7, 59:1–2 (reemphasizing that “Petitioner maintains the statements that it made in the Sherman prosecution regarding Levenson”). Petitioner attempts to rationalize the inconsistency between its statements in the Sherman prosecution (including that “Levenson does not provide any teaching with respect to [STS] pentahydrate”) and its position in this proceeding by arguing that Dr. Rogers relies on Levenson as teaching surface activation “regardless of any particular hydrates Levenson discloses.” Tr. 22:8–9. That argument is not persuasive, because Dr. Rogers’s declaration clearly states the primary reason for his opinion that it would have been obvious to a person of ordinary skill in the art to combine the teachings of Levenson with Sherman: “[b]oth references disclose synthesis of sodium thiosulfate pentahydrate.” Ex. 1008 ¶ 151. Contrary to Petitioner’s argument, Dr. Roger’s reliance on the surface activation teachings of Levenson is because he believes that both references pertain to STS pentahydrate; the surface activation teachings are not stated as an independent reason to combine the references. Id. Petitioner provides no further explanation of how a person of ordinary skill in the art would have been motivated to combine Levenson’s teachings regarding manufacture of STS heptahydrate with Sherman’s and Edwards’s teachings regarding STS pentahydrate, or how a person of ordinary skill would have regarded the difference between STS hydrates. Dr. Rogers’s acknowledgement of stability differences among STS hydrates highlights the insufficiency of Petitioner’s showing in this regard. See Ex. 2005, 35, 39.

    “We decline to adopt Patent Owner’s construction because it improperly reads into claim 5 a requirement that the specification and claim language do not support. The specification passages relied on by Patent Owner do not expressly state that a vehicle independent state must be determined while the device is inside a vehicle, and contrary to Patent Owner’s argument, they also do not necessarily imply that. For example, the descriptions of “vehicle independent movement” and “vehicle independent event” in the specification (see Ex. 1001, 1:16, 42) refer to “phone falling to the ground.” “Falling to the ground” implies that the phone may be outside a vehicle, not inside. Further, the specification’s reference to detecting a vehicle dependent state “while also” recognizing a vehicle independent event does not necessarily imply that the vehicle dependent state and vehicle independent event are being detected simultaneously, as Patent Owner argues. In the language of claim 5, a “vehicle independent state” is recited in the determining step (step c), and the requirement that the portable device is located “inside a vehicle” relates to creation of an operation indicator, as part of the detecting step (step b). Patent Owner does not dispute this, and agrees that a portable device “not in the vehicle” can satisfy the determining step (step c). Tr. 73:5–8. Patent Owner, however, argues step c’s recitation that a “vehicle independent state” is based on step b’s “predetermined criteria” creates a link between “vehicle independent state” and step b, and thus an “express requirement” in step c that the device is located inside the vehicle. See Tr. 73:8–26, 76:1–3. We decline to read this requirement into the claim language. Although the claim language states that determining a “vehicle independent state” is based on “predetermined criteria,” and step b describes comparing “predetermined criteria” to an “operation indicator” that is created when the device is inside a vehicle, it does not limit the step of determining a vehicle independent state to a time when the portable device is inside a vehicle. Accordingly, we construe “vehicle independent state” to mean a state triggered when the portable device is moved independently of the movement of the vehicle.” slip op. at 23

The Petition also maps adequately the limitations of the challenged claims to specific disclosures in Stewart (Example 2). Id. at 62–66. For example, Petitioner shows sufficiently that Yu (Example 1) coextrudes “a multilayered polymeric film,” that is, a “sheet,” arranged in the hard-soft-hard-soft-hard, five-layer configuration required by claim 11.

    “That prior art disclosure of elastomeric materials for use as the outer layers in an unclaimed and disfavored soft-hard-soft layer configuration does not convey, with reasonable clarity, that the inventors had possession of the claimed subject matter, in which the elastomeric material forms the inner layer of a polymeric sheet in a hard-soft-hard layer configuration. See id. ¶¶ 7, 33–35, 109–110. Even if the hardness limitation of the challenged claims would have been obvious from the relied-upon disclosure of the ’176 application (Ex. 2001 ¶ 109), that circumstance is insufficient to establish written description support. “Entitlement to a filing date does not extend to subject matter which is not disclosed, but would be obvious over what is expressly disclosed.” PowerOasis, Inc. v.

Where Sun teaches that the flexural modulus of dental structures would have been recognized as one such mechanical property (id. ¶ 160; Ex. 1018 ¶ 12), we further accept, at this preliminary stage, that an ordinarily skilled artisan would have understood how variations “in the relative thicknesses of the respective layers” desirably impact the flexural modulus (id. ¶ 105). Furthermore, in view of Sun’s disclosure of advantages associated with dental structures having a preferred flexural modulus, and the fact that those exact same advantages expressly were of interest to Hinz, we are not persuaded by Patent Owner’s argument, on this record, that it makes a difference that Sun discusses two-layer structures, whereas Hinz discusses three-layer structures.

In other words, Sun’s teachings appear, on this record, to apply generally to multilayer dental structures, including the multilayer structures of Hinz. For the above reasons, although the issue is a close one, we find that Petitioner shows sufficiently for purposes of trial institution that the ordinarily skilled artisan would have had a reason, and possessed the technical acumen, to select combinations of layer thickness values, from among the ranges disclosed in Hinz, to attain a multilayer dental structure having a desirable flexural modulus, as suggested by Sun.

Patent Owner is correct that Petitioner primarily relies on Example 1 as evidence for the method by which its scaffold is made.

    “Third, and most significantly, Petitioner points to Shimizu, a patent filed in 1999, as repeatedly referring to phosphor as a garnet-based fluorescent material. Reply 3 (citing Pet. 27; Ex. 1013, 10:16–13:50). We agree that Shimizu appears to use the two terms interchangeably. For example, Shimizu states that “[t]he phosphor is specifically garnet fluorescent material” and “the fluorescent material is preferably yttrium- aluminum-garnet fluorescent material (YAG phosphor) activated with cerium.” Ex. 1013, 10:17–30. Patent Owner does not dispute this reading of Shimizu, but argues instead that it is “impermissible to rely on an entirely different reference” in a Reply. See Sur-Reply 4–5 (citing Ariosa Diagnostics v. Verinata Health, Inc., 805 F.3d 1359, 1367 (Fed. Cir. 2015)). For the same reasons discussed above, we do not agree that Petitioner’s use of Shimizu is improper, but is instead a proper response to Patent Owner’s argument that a person of ordinary skill in the art would not have understood Yamazaki to disclose phosphor. Ariosa, relied upon by Patent Owner, confirms that the Board should consider an exhibit “for what it show[s] about the background knowledge that a skilled artisan would have possessed.” Ariosa, 805 F.3d at 1365 (“The Board’s language on its face supports Ariosa’s interpretation of what the Board meant—that the Board was declining to consider Exhibit 1010, even as evidence of the background understanding of skilled artisans as of January 2010, simply because the brochure had not been identified at the petition stage as one of the pieces of prior art defining a combination for obviousness. If that is what the Board meant, the Board erred. Art can legitimately serve to document the knowledge that skilled artisans would bring to bear in reading the prior art identified as producing obviousness.”). The Petition relies on Shimizu to show such background understanding. Pet. 27. Specifically, the Petition states that conventional LEDs “were made using the III-nitride material system, with semiconductor layers formed on sapphire substrates and combined with YAG phosphors to efficiently generate white light output.” Id. (citing Ex. 1013, 10:30–11:35). Thus, Shimizu is properly objective evidence supporting a finding that at least as early as 1999, a person of ordinary skill in the art would have used the terms “phosphor” and “fluorescent material” interchangeably. Moreover, Dr. Schubert’s textbook published in 2018 explicitly references Shimizu. Ex. 1039, 3-4. In this context, we find that Dr. Schubert’s textbook and testimony indicate that a person of ordinary skill in the art, at the relevant time, would have understood the terms to be interchangeable.” slip op. at 20

Petitioner cites Schubert to show an ordinarily skilled artisan’s knowledge about conventional blue LEDs as disclosed in Yamazaki, i.e., that “conventional blue LEDs were III-nitride-based LEDs that commonly included sapphire growth substrates.” See Pet. 71–72, 76–77; Ex. 1007 ¶ 27 (stating the disclosed light-emitting chip “is of a publicly known structure”); Ex. 1008, 166 (discussing “commonly used sapphire and SiC substrates”).

We are not persuaded otherwise by the deposition testimony of Dr. Dupuis pointed to by Patent Owner. PO Resp. 44 (citing Ex. 2016, 53:7– 12). This testimony confirms that Schubert does not explicitly discuss whether the sapphire growth substrate is included in an LED package. Id. (citing Ex. 2016, 53:7–12). However, Patent Owner does not dispute that sapphire growth substrates were commonly used (as confirmed by Schubert) or that a person of ordinary skill in the art would have reasonably expected a blue LED to include a sapphire growth substrate.
