“filter comprises “a third set of layers on the second side, whether the third set of layers includes oxygen.” Ex. 1001, 10:41–49. Petitioner argues that the proper construction of this limitation “means that there is a third set of layers on the opposite side of the substrate, whether or not [the layers] include oxygen” – i.e., that the third set of layers do not need to include oxygen. 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). We agree with Petitioner’s representation that each of the challenges presented either anticipates or renders obvious a third set of layers with oxygen on a second side of a substrate (Pet. 8) and therefore, no claim construction is necessary for this term.

“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.

Considering the subject matter of the ’869 patent, the background technical field, and the asserted prior art, we agree with Petitioner’s proposed qualifications for an ordinary level of skill, except we decline to adopt “at least” as that language is vague and open-ended. Otherwise, Petitioner’s proposed definition is consistent with the level of skill reflected in the Specification of the ’869 patent and the asserted prior art references. See Okajima v.

“We agree with Patent Owner that the claims are directed to the classification stage, as they require extracting “a plurality of static data points” from an executable file and “generating a feature vector from [that] plurality of static data points using a classifier” (emphasis added). The claims also recite that the classifier has been “trained to classify” (emphasis added). Further, the claims recite that “features of the feature vector” are selectively turned on or off, indicating that the feature vector has been generated. We also agree with Patent Owner that Petitioner has not shown that Ideses teaches or suggests a classification method in which one or more features of a feature vector generated from a plurality of static data points are selectively turned on or off based on the value of the static data point. As explained in the summary of Ideses above, Ideses describes “methods and systems for generating classifiers” (Ex. 1005 ¶ 2) in which “extracted features [may be] identified for pruning to generate the group of classifying features,” and “the selection [may be] based on identifying a classification effectiveness rank for each of the features of the training software applications” or “based on identifying resource requirements for each of the features of the training software applications.” See id. ¶¶ 98, 99. “[T]he group of classifying features [may be] selected based on the significance of the extracted features,” such that “[s]ignificant features, such as those that have a large effect on the classification outcomes, may be retained” and “[i]nsignificant features, such as those that have a small, negligible or no effect on classification outcome may be pruned.” Id. ¶¶ 101, 106.

“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
