    “Petitioner also fails to provide sufficient rationale and a reasonable expectation of success in combining Krishnan and Lee to arrive at a quality assessment neural network configured to receive an image. See Pet. 34–37. For example, the Petition lacks an explanation of why a POSITA would have been motivated to modify Krishnan’s quality assessment neural network to be configured to receive an image, instead of extracted features, in view of Lee’s image-receiving category classifying neural network. Id. Without such further explanation, Petitioner’s challenge falls short. Petitioner’s argument that neural networks for image quality assessment were “well-known” is not persuasive—it does not address the particular scope of limitation 1i, which also requires that the neural network is configured to receive images. Pet. 35 (citing Ex. 1002 ¶¶ 47–51, 118; Exs. 1017, 1023, 1024, 1026). Petitioner’s argument that combining Krishnan and Lee “would merely amount to applying known work from the field . . . to yield predictable results” is not persuasive because the Petition ties this reasoning to modifying Krishnan with Lee’s view-category-specific assessment parameters, not modifying Krishnan’s quality assessment neural network to receive images instead of extracted features. Id. at 37 (citing Ex. 1002 ¶ 126). Lastly, we note Petitioner’s expert’s discussion regarding neural networks for image quality assessments.

Moreover, for the reasons discussed above, we do not agree with Petitioner that Sormunen’s PIN is a token. Sormunen’s PIN is nothing more than a numerical passcode provided to a user when a charge card is ordered or when a new PIN is required because a prior PIN has been compromised. Ex. 1004, 9:28, 9:34–10:2. Given that both Sormunen’s password and its PIN are passcodes known to the user, Petitioner’s reasoning that a person of skill in the art would know from Sormunen to combine its password and PIN lacks rational underpinning. Further, Petitioner’s reasoning that a person of skill in the art “would understand that a PIN would commonly be generated by known techniques to produce a randomized string” is not supported by Sormunen, because Sormunen does not disclose a PIN produced by a randomized string. Petitioner’s reliance on Perlman does not cure these deficiencies in Petitioner’s reasoning. Pet. 35–37.

Although Patent Owner does not “concede to the correctness” of this construction in this proceeding, Patent Owner does not argue what, if anything, is wrong with this construction. Before the ITC, Patent Owner argued that the plain and ordinary meaning of “[perform/performing] speech recognition” was not broad enough to cover “hotword detection.” See Ex. 2001, 30. The ITC found Patent Owner’s position to be “untenable” because hotword detection “is a form of speech recognition in every ordinary sense.” Id. at 31. We agree with the ITC that the plain and ordinary meaning of performing speech recognition includes hotword detection. Moreover, the ’748 patent describes using speech recognition for hotword detection. Ex. 1001, 4:57–63 (“[A]udio input modules may be operable to utilize speech recognition techniques . . . to determine whether the obtained audio input includes a predetermined audio command.”).

This passage indicates speech recognition to recognize the trigger phrase (i.e., hotword detection) is performed by all the devices that receive the trigger phrase prior to any coordination determination. This passage supports Patent Owner’s argument and contradicts Petitioner’s contention that Rosenberger discloses this limitation. We agree with Patent Owner that the flaw in Petitioner’s reasoning is that the devices disclosed in Rosenberger upon receiving a spoken audio input do not make any determination as to whether speech recognition, particularly hotword detection, should be performed. All the devices perform speech recognition by performing hotword detection before the coordination determination is made. See Ex. 1003, 8:20–32.” slip op. at 18

    “D. Claim Construction We construe claim terms according to the standard set forth in Phillips v. AWH Corp., 415 F.3d 1303, 1312–17 (Fed. Cir. 2005) (en banc), i.e., as construed in a civil action under 35 U.S.C. § 282(b). See 37 C.F.R. § 42.100(b) (2020). Under Phillips, claim terms are afforded “their ordinary and customary meaning.” Phillips, 415 F.3d at 1312. “[T]he ordinary and customary meaning of a claim term is the meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention.” Phillips, 415 F.3d at 1313. “Importantly, the person of ordinary skill in the art is deemed to read the claim term not only in the context of the particular claim in which the disputed term appears, but in the context of the entire patent, including the specification.” Phillips, 415 F.3d at 1313. An inventor may rebut that presumption by providing a definition of the term in the specification “with reasonable clarity, deliberateness, and precision.” In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994). In the absence of such a definition, limitations are not to be read from the specification into the claims. In re Van Geuns, 988 F.2d 1181, 1184 (Fed. Cir. 1993).” slip op. at 11

    “Patent Owner does not directly oppose Petitioner’s definition of a POSITA. See generally Prelim. Resp. Patent Owner does, however, state that “Petitioner’s expert has proposed a definition of a POS[IT]A that does not include specific experience in the design of optical filters” and “[m]ere general experience in optical elements does not demonstrate that a POS[IT]A would have possessed the specific abilities to design a brand-new multilayer optical interference filter from scratch, or to recreate and modify the materials from Yoda, as would have been required” in the asserted combination of Pilgrim and Yoda. Prelim. Resp. 33. Based on the present record including the disclosure in the ʼ526 patent, we apply a slightly modified version of Petitioner’s definition of the level of ordinary skill in the art that removes the qualification of “at least” and clarifies some statements. More specifically, we determine a POSITA would have had a Bachelor’s degree or equivalent in physics, or in a related science or engineering field, along with five years of experience in optical element design and optical filters although additional education (e.g., a Master’s degree with exposure to optical element design and optical filters) may substitute for some industrial experience in optical element and optical filter design, and more industrial experience can substitute for a different educational background.

    “of lower refractive index layers, and two specific properties: 1) that at least one of the one hydrogenated silicon layers is thicker than one of the lower refractive index layers, and 2) that the plurality of hydrogenated silicon layers have at least a specified refractive index at a given wavelength. Ex. 1001, 11:8–16. Petitioner argues that Pilgrim teaches the desirability of an optical filter stack having specific properties, and that Yoda teaches an optical filter having the claimed layers. However, even if it would have been desirable to use Yoda’s Si:H filter layers and those layers would have had the recited refractive index properties, as Petitioner asserts, Petitioner fails to show that an ordinarily skilled artisan would have obtained Pilgrim’s cited filter properties for an optical filter stack when implementing Yoda’s filter layers in Pilgrim’s optical filter stack. The optical filter that Pilgrim discloses, and that Petitioner relies on to teach the claimed optical filter properties, has a passband that “is centered on 950 nm with a full bandwidth of approximately +/-25 nm” and a “shift in [passband] center between an [angle of incidence (AOI)] of 0 degrees and an AOI of 40 degrees [that] is approximately 15 nm.” Ex. 1004 ¶ 26. Yoda is silent with regard to whether its filter layers could be used in an optical filter having a limited shift at a passband center, as disclosed by Pilgrim. As Patent Owner points out, “no reference cited [in] the Petition describes a design for any optical filter with a center wavelength shift of 15 nm over the 0° to 40° AOI range.” Prelim. Resp. 3. And Yoda does not “consider how the center wavelength would shift based on AOI.” Id. at 22. Petitioner’s assertion that optical filter properties and the filter layer properties are “routinely optimized parameters” (Pet. 24) does not adequately explain that an ordinarily skilled artisan would have implemented the filter layer properties taught by Yoda in an optical filter to obtain the properties disclosed by Pilgrim. Still further, Petitioner’s assertion about routine optimization is conclusory and is not supported by evidence. Nor is Petitioner’s argument that one of ordinary skill in the art would have had a reasonable expectation of success in “optimizing parameters” to design a filter for Pilgrim’s application supported by adequate evidence. Petitioner must show not only “that a skilled artisan would have been motivated to combine the teachings of the prior art references to achieve the claimed invention,” but also “that the skilled artisan would have had a reasonable expectation of success in doing so.” Kinetic Concepts, Inc. v. Smith & Nephew, Inc. 688 F.3d 1342, 1360 (Fed. Cir. 2012). Petitioner’s assertion that a POSITA would have expected to succeed in optimizing the parameters and designing a filter for Pilgrim’s application and to meet Pilgrim’s design goals in light of the guidance about how various processes and parameters impacted the index of refraction and extinction coefficient of Si:H and the POSITA’s ability to simulate the performance of the filter designs using the optimized materials (Pet. 22) does not address whether a POSITA would have had a reasonable expectation of success in creating an optical filter with the required properties using the filter layers described by Yoda. Petitioner has not shown a POSITA would have had the “ability to simulate the performance of the filter designs using the optimized materials.” Pet. 22. For example, Petitioner has not discussed what specific simulation techniques or tools would have been used by a POSITA. Furthermore, although Petitioner’s expert asserts the POSITA would have been led to select hydrogenated silicon as the high-refractive index material and would have further found it obvious to design the material to increase the refractive index to meet the design goals, while still maintaining a low extinction coefficient. These goals would have been achieved by tailoring the deposition processes and conditions, as well as the hydrogen content of the hydrogenated silicon material, as was known to the POSITA (Ex. 1002 ¶ 145), that statement does not explain how the tailoring the deposition processes and conditions and the hydrogen content would have led to successfully maintaining the low extinction coefficient, let alone to successfully creating an optical filter with Pilgrim’s required passband characteristics. Rather, as Patent Owner points out, the evidence cited in the record before us suggests “the design of [an optical] bandpass interference filter with a narrow bandwidth and low center wavelength shift is not trivial.” Prelim. Resp. 31 (citing Ex. 1001, Fig. 7C). Specifically, in detailing the requisite filter layers for an exemplary filter, the ’526 patent describes a filter stack of 48 layers of materials having varying thicknesses, an “[antireflective] coating includ[ing] 5 layers, and the total coating thickness [being] about 5.7 µm.” Ex. 1001, 8:1–12, Figs. 7B–7C.” slip op. at 21

    “Additionally, while Petitioner is correct that Figure 3 of Dawson illustrates a “direct connection” between CS (355) and +VDD (390) (Pet. 40– 41), that aspect of the Figure 3 embodiment was not included in Petitioner’s combined embodiment. Petitioner does not rely on the Figure 3 embodiment to teach or suggest all of the elements of independent claim 1, and Petitioner cannot rely on such a connection, only found in the Figure 3 embodiment, unless Petitioner explains how it would be incorporated in the combined embodiment and why one of ordinary skill in the art would have provided for such a connection. Although the Petition provides a rationale for the creation of the combined embodiment, the Petition does not assert that one of ordinary skill in the art would have been motivated to incorporate the “direct connection” aspect of Figure 3 into the combined embodiment. Similarly, Petitioner also argues that “Figure 6 also shows the second electrode of a capacitor is directly connected to the first line because a POSITA would design the VDD line to be extended to run parallel to data line 220.” Pet. 41 (citing Ex. 1002 ¶ 206). This is unavailing because we have no proffered rationale why such line would be extended, with only a conclusory statement provided in the Petition and Dr. Kanicki’s testimony adding nothing additional. The annotated Figure 6 (Pet. 42), provided by Petitioner in the Petition, provides no support for Petitioner’s assertions as it appears that the red line on that figure would tie the source and drain of TFT P3 (610) together, shorting the TFT and rendering it inoperable. We find it difficult to discern Petitioner’s intent or position from the section of the Petition discussing claim element [1.18], but we nonetheless can determine that it does not appear to be supported by any recognizable evidence.” slip op. at 15
