“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).

“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.

“Patent Owner’s expert, Dr. Goodrich, proposes what Patent Owner characterizes as “a somewhat different level,” namely “an individual with at least a bachelor’s degree in Computer Science or related area and two years of experience developing software tools and/or computer systems for use in the area of audio or video creation, encoding, and/or distribution.” PO Resp. 13; Ex. 2007 ¶ 50. Although we agree that the respective articulations are “somewhat different,” they are generally similar, and our Decision does not depend on nuanced distinctions regarding the level of ordinary skill. Indeed, Dr. Goodrich describes his proposed articulation as “approximate,” such that “more work experience could compensate for less education or more education could compensate for less work experience.” Ex. 2007 ¶ 50. Because we find Petitioner’s proposal reasonable, consistent with the level of skill reflected by the prior art, and supported by Dr. Freedman’s testimony, we adopt it for this Decision. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (the prior art may reflect an appropriate level of skill in the art).

- Claim Construction › Intrinsic evidence (Phillips canons) › Lexicography (patentee as own lexicographer)Term construed board ownDecided for patent owner
“We agree with Patent Owner’s contention that the emphasized sentence defines the term “content-related.” See PO Resp. 15–16 (Patent Owner arguing that “[t]here are thus three strong indications of lexicography: (1) ‘content-related’ is set off by quotation marks; (2) the patentee used the word ‘is’ to describe the term ‘content-related’; and (3) the patentee states what ‘content-related’ is ‘understood to mean.’” Nor does Petitioner disagree that the sentence is definitional. See Tr. 8:15–16 (referring to the “term content-related as it’s defined in the specification”). Indeed, in the Starz litigation, the district court also treated the sentence as definitional, a fact that we find significant as a matter of comity. See Ex. 1018, 111:24–112:1 (district court judge stating at Markman hearing, “I’m going to adopt . . . the express definition provided in the specification”). But like the district court, we discern insufficient reason to adopt the additional gloss that Patent Owner seeks to apply to the definition of “content-related.” That is, Patent Owner proposes that we additionally construe the phrase “syntactical meaning” within the definitional statement to arrive at Patent Owner’s proposed construction. PO Resp. 16–20. According to Patent Owner, “[t]he specification makes clear, through its use of consistent and repeated examples, that ‘syntactical meaning’ requires a specific relationship between the data segments within a data file: succeeding data segments within a data file must be ordered so as to present the content in its intended sequence when rendered.” Id. at 17 (citing VirnetX Inc. v. Cisco Sys., Inc., 767 F.3d 1308, 1317–19 (Fed. Cir. 2014); Alloc, Inc. v. ITC, 342 F.3d 1361, 1368–71 (Fed. Cir. 2003)). Patent Owner adds that the claims, the context provided by the problems solved by the ’794 patent, and the cross-examination testimony of Petitioner’s expert, Dr. Freedman, all support this additional aspect of Patent Owner’s proposed construction. Id. at 18–20. Relying on additional direct testimony by Dr. Freedman, Petitioner counters this position as “improperly import[ing] limitations from the specification that are not required by the claims” and “render[ing] other portions of claim 1 superfluous.” Reply 3 (citing Ex. 1016 ¶ 22); see Tr. 10:18–20 (Petitioner explaining at oral hearing that “the syntax information is simply just identification information which is used to find out what the order of the files is. But the identification information does not by itself indicate the order. It’s just an identifier.”). We agree with Petitioner that it would be imprudent to adopt Patent Owner’s additional gloss because, “[w]hile claims must be construed in light of the specification, . . . limitations from the specification are not to be read into the claims, . . . for ‘[i]t is the claims that measure the invention.’” Golight, Inc. v. Wal-Mart Stores, Inc., 355 F.3d 1327 (Fed. Cir. 2004) (quoting SRI Int’l v. Matsushita Elec. Corp. of Am., 775 F.2d 1107, 1121 (Fed. Cir. 1985) (other citations omitted). It is apparent that the Applicant for the ’794 patent understood how to define terminology recited in the claims, but chose to limit its definition of “content-related” in terms of the broader phrase “syntactical meaning” rather than through narrower specific reference to presentation order. In addition, claims 1 and 9 already specify “sequentially outputting the first and second data segments according to their chronological sequence,” which supports Petitioner’s observation that requiring an additional sequential order to “content-related . . . data segments” renders other portions of claim 1 superfluous.

“As a basic principle of claim interpretation, prosecution disclaimer promotes the public notice function of the intrinsic evidence and protects the public’s reliance on definitive statements made during prosecution.” Omega Engineering, Inc. v.

As such, a statement during prosecution qualifies as a disavowal of claim scope only if it is “so clear as to show reasonable clarity and deliberateness” and “so unmistakable as to be unambiguous evidence of disclaimer.” Id. at 1325 (citations omitted). “Consequently, for prosecution disclaimer to attach, [Federal Circuit] precedent requires that the alleged disavowing actions or statements made during prosecution be both clear and unmistakable.” Id. at 1325–26. “The party seeking to invoke prosecution history disclaimer bears the burden of proving the existence of a clear and unmistakable disclaimer that would have been evident to one skilled in the art.” Mass.

“We agree with Petitioner’s contention that “memory module” is not limited to “main memory modules . . . designed to connect to the primary memory controller.” See Reply 2. The ’054 patent states In certain embodiments, the device contains a high density Flash memory with a low density DRAM, wherein the DRAM is used as a data buffer for read/write operation. The Flash serves as the main memory. Ex. 1001, 11:3–6 (emphases added). This is the only mention of “main memory” in the ’054 patent. That the Flash memory serves as “main memory” in “certain embodiments” implies that there may be other embodiments in which this is not the case. Accordingly, we agree with Petitioner that the term “memory module” is not limited to “main memory modules . . . designed to connect to the primary memory controller.” We agree with Patent Owner that the “memory module” includes structure to connect with a “host system” including its memory controller. See, e.g., Ex. 1001, code (57), 12:52–59. The claims do not mention a “memory controller,” but they do mention that the “memory module” has an “interface” to connect with a “host system.” Ex. 1001, 38:20–25 (claim 1), 39:63–65 (claim 16), 41:6–8 (claim 24). That the “memory module” has structure for connecting to the host system’s memory controller may thus be implied from the claims. We agree with Petitioner that the District Court’s determination was that the preambles (presumably of claims 1, 4, 6, 11, 16 and 25) are limiting. Ex. 2032, 35. To the extent that the District Court’s determination construed “memory module” to include structure necessary to connect to a memory controller, our construction of “memory module” is consistent.” slip op. at 16

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“conversion for double-rank DIMMs can be accommodated with a form factor design of approximately about one square inch (both sides of the printed circuit board).” Ex. 1023 ¶ 13. Thus, Harris indicates that the VRM circuitry to generate two regulated voltages can fit within this space. Patent Owner argues that Petitioner’s evidence shows that each ADP1821 converter package would be about 0.193 by 0.236 inches. Sur-Reply 12 (citing Ex. 1078, 20–23). This means three ADP1821 converters would occupy about 40% of the available space. Patent Owner does not demonstrate that the remaining 60% of available space would have been insufficient to accommodate the additional components required for three voltage converters. Id. at 12–13. In any case, we do not view Harris’s disclosure of “approximately about one square inch” to limit the applicability of its teachings to a person of ordinary skill in the art. In the same paragraph, Harris states that the form factor “may be suitably modified.” Ex. 1023 ¶ 13. Patent Owner further argues that “independent voltage sources for different voltages would require specific control circuitry to delay and more precisely control each voltage source’s ramping rate, adding complexity and cost without commensurate benefits.” Sur-Reply 14 (citing Ex. 2061 ¶ 90). However, Dr. Wolfe states that it is simpler to use multiple regulators for multiple voltages since a single regulator that generates multiple voltages is more complicated than multiple regulators. Ex. 2060, 53:16–54:14, 89:1–21, cited in Reply 14. Dr. Wolfe further indicates that buck converters can be in some applications “extremely small.” Ex. 2060, 89:11–15. Dr. Wolfe further testifies that multiple smaller converters may be less costly than a larger single converter because of component costs, separated spaces available for converters on circuit board, and other “ordinary engineering factors.” Id. at 45:21–46:10. Although Patent Owner may be correct that individual control of multiple voltage regulators would have required additional control circuitry, this does not meaningfully undermine the benefits that Petitioner mentions including permitting power sequencing, independent control of voltages, improved efficiency without generating excess heat or requiring cooling devices, and saving power. Pet. 29–30 (citing id. at 14–19; Ex. 1028, 17–20; Ex. 1026, 2–3, 9; Ex. 1028, 30–32; Ex. 1040, 1, 23–24 (Figs. 22–25); Ex. 1041, 1, 13; Ex. 1048, 3; Ex. 1058, 5; Ex. 1059, 5:23–30; Ex. 1062, 11, 13; Ex. 1064 ¶ 101; Ex. 1003 ¶¶ 240, 255). Dr. Wolfe testified that, in at least some circumstances, multiple converters may be less complicated, less costly, and take up less space. Ex. 2060, 45:21–46:10, 89:11–15. Patent Owner’s argument that a single converter generating multiple voltages would be better in some circumstances does not negate that Petitioner’s proposed use of multiple converters for multiple voltages would have been preferred in other circumstances that a person of ordinary skill in the art would have recognized. See Intel Corp. v. Qualcomm Inc., 21 F.4th 784, 800 (Fed. Cir. 2021) (“Our caselaw is clear. It’s not necessary to show that a combination is ‘the best option, only that it be a suitable option.’” quoting PAR Pharm., Inc. v. TWI Pharms., Inc., 773 F.3d 1186, 1197–98 (Fed. Cir. 2014)).
