    “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).

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.

    “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.

    “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.

    “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.

    “disseminated to the interested public, ‘public accessibility’ has been called the touch-stone in determining whether a reference constitutes a ‘printed publication’ . . . .” Jazz Pharm., Inc. v. Amneal Pharm., LLC, 895 F.3d 1347, 1356 (Fed. Cir. 2018) (quoting In re Hall, 781 F.2d 897, 898–99 (Fed. Cir. 1986)). A reference is considered “publicly accessible” if it was “disseminated or otherwise made available to the extent that persons interested and ordinarily skilled in the subject matter or art, exercising reasonable diligence, can locate it.” Id. at 1355–56 (citing In re Wyer, 655 F.2d 221, 226 (CCPA 1981)). Petitioner treats this requirement as having two aspects, namely (1) whether a person of ordinary skill could reasonably have found RemoteCentral.com and (2) whether such a skilled artisan could reasonably have found RadioShack on RemoteCentral.com. Reply 8–13; see also Tr. 33:25–34:8 (Patent Owner asserting that there are two aspects to the analysis on public accessibility: “The first is whether a [person of ordinary skill in the art] would have known to arrive at the website containing the prior art reference. The second one is . . . , [a]ssuming the [person of ordinary skill in the art] would have done so, would the [person of ordinary skill in the art], exercising reasonable diligence, have located the prior art reference on the site?

    “addressed squarely by the principles set forth in Hulu, which addresses the standards at the institution stage and during the trial for evaluating evidence proffered to show asserted art qualifies as a printed publication. Specifically, after a petitioner has presented “evidence sufficient to establish a reasonable likelihood that the reference was publicly accessible before the critical date of the challenged patent,” such that trial is instituted, “some limited opportunities exist for the petitioner to present new evidence later.” Hulu at 13–14. These “limited opportunities” include “in a reply to the patent owner response,” provided that the additional evidence is “responsive to the prior briefing” and provided that the additional evidence does not require “completely reopen[ing] the record, by, for example, changing theories after filing a petition.” Id. at 14–15. Although Patent Owner contends that “[t]his is not an example of permissible rebuttal evidence, but rather a belated attempt to fill a gap in the evidence in the Petition,” we disagree. See Sur-reply 6. Rather, the 7 Patent Owner appears to refer incorrectly to Exhibit 1040 instead of Exhibit 1041 when identifying “articles allegedly referring to RemoteCentral.com.” See Sur-reply 5–6. progression within the instant proceeding comports well with the Hulu framework. During the preliminary proceeding, Petitioner came forth with “evidence sufficient to establish a reasonable likelihood that [RadioShack] was publicly accessible before the critical date of the challenged patent,” just as Hulu demands. Hulu at 13; Inst. Dec. 23 (“[W]e determine that Petitioner’s showing regarding public accessibility of RadioShack is sufficient under the standard we apply at this stage of the proceeding.”). Patent Owner challenges RadioShack’s status as a printed publication in its Response, just as Hulu contemplates. Hulu at 15; PO Resp. 28–41. And Petitioner submits additional evidence that replies to that challenge without changing its theory that RadioShack qualifies as a printed publication by virtue of its accessibility on the RemoteCentral.com web site and in light of date indicia on RadioShack itself.8 See Hulu at 15–16; Reply 7–13. Moreover, in determining that Petitioner’s additional evidence directed at RemoteCentral.com is properly considered, we are further mindful of the Federal Circuit’s endorsement that “the petitioner in an inter partes review proceeding may introduce new evidence after the petition stage if the evidence is a legitimate reply to evidence introduced by the patent owner.” Anacor Pharm., Inc. v. Iancu, 889 F.3d 1372, 1830–81 (Fed. 8 In its Reply, Petitioner also relies on evidence of publication of RadioShack on Radio Shack’s own public website and on “a third location,” hifi-remote.com. Reply 14. As we discuss below, we determine that the presence of RadioShack on RemoteCentral.com is sufficient to qualify RadioShack as a printed publication. We therefore do not reach the issue of whether presence on either the Radio Shack web site or on hifi-remote.com is an improper new theory raised by Petitioner in its Reply. See Tr. 8:13– 9:23 (Petitioner discussing whether reliance on hifi-remote.com presents a different theory than set forth in the Petition). Cir. 2018); see also Vidstream LLC v. Twitter, Inc., 981 F.3d 1060, 1065 (Fed.

We conclude that the Board acted appropriately, for the Board permitted both sides to provide evidence concerning the reference date of the Bradford book, in pursuit of the correct answer.”).

    “We disagree with Patent Owner’s arguments because, as Petitioner points out, the evidence shows that DDR3 devices do not always have edge-aligned data and strobes. See Pet. Reply 4. In particular, Patent Owner’s declarant Dr. Mangione-Smith testifies that the DDR3 standard allows a 200 picosecond maximum DQS-to-DQ skew, “which is a very tight tolerance considering the speed at which the memory devices are operating.” Ex. 2006 ¶¶ 122–125 (citing Ex. 1020, 164). During cross-examination of Dr. Mangione-Smith, Petitioner established that a 200 picosecond tolerance is actually a misalignment of over 28 degrees considering the 2.5 Pet. Reply 4 (discussing this testimony). Thus, the evidence shows that DDR3 data and strobes are not always edge-aligned. Patent Owner dismisses this, stating that “Petitioner’s argument is tantamount to saying that the JEDEC standard prescribes a tolerance for DQS/DQ skew that causes errors, which runs counter to the entire standard-setting process.” PO Sur-reply 3–4. On the contrary, we find that Petitioner’s showing underscores that Butt’s read training has direct applicability to a memory that may potentially skew by as much as 28 degrees. Butt explains that read training is used “to establish optimum DQS strobe settings” and thereby “enables a reliable data read operation for high speed applications.” Ex. 1029 ¶¶ 33, 36; see Pet. 44–47 (discussing this disclosure). As the Supreme Court has stated, “if a technique has been used to improve one device, and a person of ordinary skill in the art would recognize that it would improve similar devices in the same way, using the technique is obvious unless its actual application is beyond his or her skill.” KSR, 550 U.S. at 417. “This is the so-called ‘known-technique’ rationale. And if there’s a known technique to address a known problem using ‘prior art elements according to their established functions,’ then there is a motivation to combine.” Intel Corp. v.

We find that Butt’s read training is such a known technique that would improve Hiraishi’s memory based on the benefits identified in Butt and discussed above, i.e., “establish[ing] optimum DQS strobe settings” to enable “reliable data read operation for high speed applications.” Ex. 1029 ¶¶ 33, 36. timing operation” to account for flight time differences between memory devices, pointing to Hiraishi’s retiming operation that is performed after the data are loaded in FIFO (Read) circuit 302. PO Resp. 45 (citing Ex. 1005 ¶ 130). But Petitioner’s obviousness contentions are based on adjusting the timing of strobes before the data are registered in (loaded into) FIFO (Read) circuit 302. See Pet. 35–37 (asserting that the delayed read strobe is “the DQS signal supplied to FIFO (Read) circuit 302,” which is then used to register the data in FIFO (Read) circuit 302). Thus, Patent Owner is pointing to an entirely different operation. Furthermore, even if Hiraishi discloses some mechanism to cope with misaligned data and strobes, we find that Butt’s technique is a “suitable option” in combination with Hiraishi. See Intel, 61 F.4th at 1381. Indeed, in such a case, Hiraishi and Butt “address the same problem,” and Butt’s read training “was a known way to address that problem[, which] is precisely the reason that there’s a motivation to combine under KSR and [Federal Circuit] precedent.” Intel, 61 F.4th at 1380.
