    “Patent Owner did not dispute that the combined teachings of Kumada and Debladis ’120 disclose each limitation of claim 1. Patent Owner, however, did dispute Petitioner’s proposed reasons for combining Kumada and Debladis ’120, and argues that Debladis ’120 is not analogous art. PO Resp. 36–61. The Federal Circuit stated that substantial evidence only supports the conclusion that a POSA would have been motivated to combine the teachings of Kumada and Debladis ’120. The factual record and Willis’s concession on appeal conclusively establish that the cost of copper was a known problem in the art, Debladis ’120 (and Kumada) helped address that issue, and Willis has not disputed that combining the teachings of Kumada and Debladis ’120 was within the skill of an ordinary artisan. Nothing more is required to establish a motivation to combine. Given that Willis has conceded that the combination of Kumada and Debladis ’120 disclose all the limitations in claim 1, we reverse the Board’s patentability determination as to that claim and vacate the Board’s judgment as to the remaining claims of the ’037 patent. Everstar II, 2025 WL 1501940, 4 (internal citations omitted). The Federal Circuit further noted Patent Owner’s secondary considerations arguments as to claim 1 and stated [t]he cited evidence consists only of a temporal connection between the introduction of Willis’s invention and the UL 588 standards, and deposition testimony of a single witness who seemingly disclaimed any connection between the two. This is not sufficient to rescue a claim as to secondary considerations. Id. at 4, n. 5 (internal citations omitted).

Pet. 7–8. Patent Owner agrees that this is the “literal” reading of the language, but contends that one of ordinary skill in the art “would have appreciated that this language was intended to read ‘wherein’ rather than ‘whether’” and that the claim requires that this set of layers must include oxygen. PO Resp. 24–26 (citing Ex. 2001 ¶¶ 53–55).

    “415 F.3d at 1314): “a first set of layers on the first side, wherein the first set of layers includes silicon and hydrogen” (claim 1) and “a first set of layers including silicon and hydrogen” (claims 9 and 15). Ex. 1001, 10:41–49, 10:65–11:4, 11:17–12:5. As the parties agree, these recitations are broadly worded. See Pet. 14 (describing the recitations of the claims as “broad” and directed to “layers of any material that has both ‘silicon and hydrogen’”); PO Resp. 42 (describing the claims as “simply specifying physical layers including silicon and hydrogen in them”), 44 (describing the disputed terms as “open-ended claiming of layers including hydrogen and silicon”). Despite this broad language, Patent Owner contends that we must read “layers including silicon and hydrogen” in conjunction with other limitations in the claims reciting a “near infrared bandpass filter.” PO Resp. 35–37 (citing Ex. 2001 ¶¶ 65–66). For purposes of our analysis, we limit “layers including silicon and hydrogen” to only materials suitable for NIR bandpass filters, as suggested by Patent Owner. We next examine the rest of the intrinsic evidence. The specification of the ’794 patent does not contain language that generally describes “layers including silicon and hydrogen.” Instead, the specification describes only layers of hydrogenated silicon: its abstract is directed to an “optical filter” that “includes a filter stack formed of hydrogenated silicon layers” (Ex. 1001, code (57)); the technical field of the invention is described as “relat[ing] to optical filters including hydrogenated silicon layers and to sensor systems comprising such optical filters” (id. at 1:20–23); the summary of the invention describes “the present invention” as an optical filter or sensor system “comprising” “a plurality of hydrogenated silicon layers” (id. at 2:57–3:19); and the detailed description begins with a hydrogenated silicon (Si:H) layers” (id. at 4:19–20). The specification only mentions silicon and hydrogen separately with respect to the disclosed sputter-deposition system “used to produce the hydrogenated silicon material.” Id. at 4:35–5:61, 7:10–19. In particular, the specification describes how “cathode 430 includes a silicon target 431, which is sputtered in the presence of hydrogen (H2), as well as an inert gas such as argon, to deposit the hydrogenated silicon material as a layer on the substrate 420.” Id. at 4:44–47. The specification also describes how altering the hydrogen flow rate in the deposition process affects the optical properties of hydrogenated silicon produced by the deposition system. See id. at 5:1–61. But the only end product described from the sputter-deposition process using silicon and hydrogen is hydrogenated silicon. See id. at 4:35–5:61, 7:10–19. As such, the specification does not provide any indication of materials beyond hydrogenated silicon that are within the scope of “layers including silicon and hydrogen.”” slip op. at 15

  • Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner

    “hydrogen” defines a genus. The test for providing a written description that supports a genus claim is whether the description provides “either a representative number of species falling within the scope of the genus or in the art can ‘visualize or recognize’ the members of the genus.” Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1350 (Fed. Cir. 2010) (en banc). “Regarding whether common structural features must exist between a claim and a putative priority disclosure, those features must constitute the near-entirety of the structures being compared.” Regents of the Univ. of Minnesota v. Gilead Scis., Inc., 61 F.4th 1350, 1358 (Fed. Cir. 2023). Yet the patentees only disclosed hydrogenated silicon as a possible species. Indeed, the specification focuses on a singular example of a sputterdeposition system that is used to produce an improved hydrogenated silicon material. See Ex. 1017 ¶¶ 36–38. Patent Owner cites this deposition process as written description support for “the claimed layers containing silicon and hydrogen.” See PO Resp. 44. But this example supports only how to make hydrogenated silicon and does not include any indication about what other materials would be within the scope of the claimed genus. Under these circumstances, the specification’s disclosure of a single species is not an adequate number to show possession of the entire genus of “layers including silicon and hydrogen.” Beyond the disclosure of the sputter-deposition process for producing hydrogenated silicon, Patent Owner does not identify—and we cannot discern—any other examples of a “structure, formula, chemical name, physical properties, or other properties, of species falling within the genus sufficient to distinguish the genus from other materials.” Ariad, 598 F.3d at 1350. This is particularly noteworthy given that undisputed record evidence shows numerous other potential filter materials “including silicon and hydrogen.” See supra § II.D.1.a.

Pet. 23–24 (citing Ex. 1008 ¶ 47; Ex. 1005 ¶¶ 66–67). Petitioner, however, proffers insufficient evidence or argument that the content choices described in paragraph 47 of Muthukumarasamy would have led an ordinarily skilled artisan to understand a media player is obtained and loaded in the content presentation device.

Additionally, Petitioner has not shown, for the zHub/zNode process, that Hayward cures the deficiencies of Muthukumarasamy as set forth above. Accordingly, Petitioner has not shown that the combination of Muthukumarasamy and Hayward teaches “receiving, in a server system, one or more messages from a personal computing device . . . wherein the one or more messages, . . . identify a particular media player for playing content from the file wherein the media player is a computer application operable to present content and control presentation of the content,” as recited in claim 1 and commensurately recited in independent claim 6.

    “However, Patent Owner’s arguments regarding the combination are directed towards a bodily incorporation of structures described in the references, rather than the combination of their teachings proposed by Petitioner. In re Mouttet, 686 F.3d 1322, 1332 (Fed. Cir. 2012) (“The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference.”); In re Keller, 642 F.2d 413, 425 (CCPA 1981). Given the teachings in each reference and our direction that an ordinarily skilled artisan is a person of ordinary creativity, we find, on this preliminary record, that Petitioner has adequately shown that an ordinarily skilled artisan would have applied Lairson’s teachings regarding a short-pass filter with Erdogan or Tsai-133’s teachings concerning filter layers on both sides of a substrate used to form a bandpass filter. KSR, 550 U.S. at 421 (“A person of ordinary skill is also a person of ordinary creativity, not an automaton.”). Petitioner’s proposed combination does not involve adding the exact layers taught in Erdogan and Tsai-133 on the second side of the substrate to Lairson’s short-pass filter on the first side of the substrate. Pet. 33–34, 36– 39. Rather, Petitioner proposes, in one example, using the same materials for filter stacks on both sides of the substrate. Id. at 37–38. Thus, Patent Owner’s arguments that adding the second-side layers disclosed in Erdogan and Tsai-133 to the first-side layers of Lairson is not responsive to Petitioner’s proposed combination. Additionally, on the present record, we credit Petitioner’s declarant’s uncontroverted testimony that Lairson does not explicitly describe a bandpass filter with a long pass filter, and thus that one of ordinary skill would have looked to Erdogan and Tsai-133 for the technique of using a long-pass filter on the other side of the substrate. Id. at 34–37 (citing Ex. 1002 ¶¶ 152, 158). On the present record, and for the purposes of institution, Petitioner sufficiently shows that the combination of Lairson and either Erdogan and Tsai-133 teaches a near infrared band pass filter comprising a first set of layers on the first side, wherein the first set of layers includes silicon and hydrogen, and a second set of layers on the first side, wherein the second set of layers includes oxygen. Additionally, on the present record and for the purposes of institution, Petitioner sufficiently sets forth its showing with respect to the motivation to combine the teachings of Lairson with those of Erdogan or Tsai-133 as it proposes.” slip op. at 21

    “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.

    “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
