“In the Decision on Institution, we adopted a slightly modified version of this definition in which we removed the open-ended term “at least.” Inst. Dec. 10–11. Patent Owner does not address the definition of a POSA. See generally PO Resp. Patent Owner’s declarant Dr. Clemens applies Petitioner’s definition, but does not opine on whether it is correct. Ex. 2001 ¶¶ 22–23. As in the Decision on Institution (Inst. Dec. 10), we apply the same slightly modified version of Petitioner’s definition of the level of ordinary skill in the art that removes the open-ended term “at least.” We determine this level of skill comports with the qualifications a person would have needed to understand and implement the teachings of the ʼ794 patent and the” slip op. at 11

“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

“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. In the absence of structural description supporting “layers including silicon and hydrogen,” we determine that an” slip op. at 19

“that “hyperlink” is a well-understood term that the ’022 patent uses in accordance with its ordinary meaning. As explained above, the Microsoft Computer User’s Dictionary makes clear that a hyperlink includes a connection to another element or document. Patent Owner points to no persuasive evidence that the ’022 patent describes a hyperlink as separate from this connection such that the connection can be changed with the hyperlink remaining the same. Indeed, the ’022 patent describes “replac[ing] all links in the translated web page 7 with links that point to the translation manager 4” as part of the translation process. Ex. 1001, 3:37–38. Thus, as described in the patent, changing the connection to point to the translation manager requires a new link. This is consistent with the ordinary meaning of a hyperlink as including a specific connection from one document to another element or document. Our preliminary construction of “hyperlink” included “a link or connection” but did not include a recitation of the element or document linked. To resolve the parties’ dispute, consistent with the ordinary meaning and the specification, we conclude, on the full record before us, that one of ordinary skill in the art at the time of the invention would have understood “hyperlink” to mean “a connection between an element in a hypertext document, such as a word, phrase, symbol, or image, and a different element in the document, another hypertext document, a file, or a script.”” slip op. at 10

“First, the inter partes reexamination of the ’022 patent is relevant to our consideration of the claim construction issues presented here because claim construction was at issue in the reexamination. Second, we see no risk of undue prejudice that would outweigh the probative value of the documents and evidence submitted in the reexamination. Of note, is that this proceeding is not a jury trial and, thus, the risk of prejudice in this forum is less than what may otherwise exist before a jury. Third, we agree with Petitioner that Exhibit 1013 is not hearsay at least under Federal Rule of Evidence 801(d)(2)(B) because the testimony in Dr. Nakhimovsky’s Declaration was submitted by, and on behalf of, Patent Owner to the Patent Office, thus evidencing that Patent Owner manifested a belief that the statements contained therein were true. Accordingly, Patent Owner’s Motion to Exclude as applied to Exhibit 1013 is denied.” slip op. at 22

“Patent Owner’s first argument is contrary to our constructions of the term “hyperlink” and the phrase “said hyperlink.” As reflected in our construction, “said hyperlink” in each of independent claims 1, 17, and 26, refers back to the original recitation of “one or more hyperlinks” in the original (untranslated) electronic communication. The portion of the specification relied upon by Patent Owner does not disclose providing translation of said further electronic communications when the original one or more hyperlink is activated. Rather, this disclosure indicates that the translation manager may replace all of the links (i.e., hyperlinks) in the translated web page with links that point to the translation manager. These replaced links are in the translated electronic communication (e.g., web page 7), and not in the original untranslated electronic communication (e.g., web page 2). Thus, this disclosure does not reasonably convey to one of ordinary skill in the art that the inventors had possession of a translation manager that provides translation of further electronic communications when the one or more hyperlinks in the original untranslated electronic communication is activated (i.e., one or more hyperlinks with unmodified destination addresses). See Ariad Pharm., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc).” slip op. at 25
