“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.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner
“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

“With respect to this rationale, we are not persuaded by Patent Owner’s arguments. The first part of the claim construction, namely rules not being properly defined and “produc[ing] an undesired effect,” does not specify an error being “internal” to the configuration engine. The specification provides that such a configuration error “may occur when a rule or series of rules is not properly defined and produces an undesired effect, such as the exclusion of a part that should be selectable” (Ex. 1001, 1:54–61, emphasis added), but the latter clause provides only one example of the undesired effect. While it seems clear that “internal” errors may result in a “configuration error,” we are not persuaded that the specification limits the term to only such errors. Further, the recitation in the specification that the invention is concerned with configuration errors in a system for configuring products describes generally the context of such configuration errors, and not that they need to be explicitly “in” the system. As such, we are not persuaded that “configuration errors,” as recited in the instant claims must be limited to errors contained in the configuration engine.” slip op. at 10

We find it curious that Patent Owner has not polled its own expert declarant or provided other evidence such as a survey of the appropriate literature at the time that the application that resulted in the ’766 Patent was filed to provide a showing of what the appropriate understanding of “configuration error” would have been. Looking to the examples cited in Dr. Woods testimony, they are purely exemplary, and he is certainly not definitive, as Patent Owner appears to acknowledge, when using the term “configuration error.” Patent Owner seeks to have us give weight to the portions that seem to support its understanding of the claim term, but give less weight to portions that do not, asserting the latter to be guided only by hindsight. This does not even address Patent Owner’s other assertions that Dr. Woods declaration should be entitled to little weight because it is “incomplete.” PO Resp. 37–39. In sum, according to Patent Owner, we should pick and choose aspects of Dr, Wood’s testimony to support Patent Owner’s contention, where the overall declaration should be given little weight. Looking at the totality of Dr. Wood’s testimony and his deposition testimony (Exs. 1002, 2005), we are not persuaded that it supports the proposition that Patent Owner relies upon to illustrate, namely that those of skill in the art would have known that configuration errors are internal to the configurator. Exemplary of this, Dr Wood avers that “[t]hroughout my Declaration I provide context of other configuration errors that would be understood by a person of ordinary skill in the art at the time of the patent. They can include syntax types of errors, semantic errors, logical errors, logical rule errors, as examples.” Ex. 2005, 59:22–60:05.

In particular, Patent Owner contends, “the preamble of claim 1 [is] limiting because it serves as antecedent basis for multiple terms in the body of the claim, and it supplies ‘essential structure’ of the claimed invention” (PO Resp. 9). Petitioner does not address this contention (see Pet. Reply 4–5). We agree with Patent Owner that the preamble is limiting because the body of the claim refers to the user program as well as the automatic test equipment (Ex. 1003, 13:57–58, 14:14–17; see Catalina Mktg. Int'l, Inc. v. Coolsavings.com, Inc., 289 F.3d 801, 808 (Fed. Cir. 2002) ([D]ependence on a particular disputed preamble phrase for antecedent basis may limit claim scope because it indicates a reliance on both the preamble and claim body to define the claimed invention”)). Patent Owner asserts the following limitation, “a channel circuit having a signal connection point adapted to be coupled to a signal line of a unit under test to receive an input signal having a value” (Ex. 1003, 13:58–61), “although formatted within the same paragraph as the preamble[,] is not actually part of the preamble, but rather part of the body of the claim” (PO Resp. 10). However, further in its argument, Patent Owner flips its statement in arguing “input signal having a value” and contends this is a “requirement[] of the preamble” (id. at 11). Petitioner’s contentions are only directed to the limitation (Pet. Reply 4–5).” slip op. at 12

“Initially, we note the claim recites “a channel circuit having a signal connection point adapted to be coupled to a signal line of a unit under test to receive an input signal having a value” (Ex. 1003, 13:58–61), Thus, due to the recitation, we determine the input signal could be either that the signal connection point receives an input signal or the channel circuit receives an input signal (id.). The next limitation recites the comparison sub-circuit has “a signal input . . . wherein each of the comparison sub-circuits is adapted to produce a comparison output signal at the comparison output having a value input signal” (id. at 13:62–14:3). The claim does not recite that the “signal input” receives “the input signal.” Nevertheless, in light of the claim language and the Specification and because Petitioner has contended both interpretations are shown, we interpret the recited “input signal” as the signal received from the UUT. The portion of the ’479 Patent describing, in part, Figure 1, cited by Patent Owner discloses ATE 139 includes multiple instruments that may generate and measure signals. A host computer 120 executes a software program that controls operation of each of the instruments. Host computer 120 may be programmed to analyze these outputs to determine whether the system under test 189 is operating properly. Such programming is traditionally a part of a user program and drives programmed values and compares measured values to expected values on one or more signal lines connected to the UUT. These steps may be programmed for multiple lines for multiple test cycles (Ex. 1003, 3:32–51; PO Sur-reply 3). The ’479 Patent further describes an “ATE . . . provide[s] stimulus to . . . the UUT and then measure[s] the output to determine if the UUT has performed to its specifications” (Ex. 1003, 1:30–33; PO Sur-reply 3). Thus, these descriptions support both interpretations. Nevertheless, the ’479 Patent describes a signal being supplied and compared to expected values. Accordingly, we interpret “an input signal” as being the signal received from a unit under test (UUT).” slip op. at 14

“We determine Schinabeck teaches the structure of the comparison sub-circuits recited in claim element 1a. Indeed, given that switches and comparators were known (Tr. 35:5–8; Ex. 1026, 17:17–18:8, 30:16–22), we determine switching certain switches on or off is a switch performing the same function it had been known to perform, yielding no more than one would expect from such an element (KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007)). Thus, turning switches off or on in Schinabeck’s circuitry, would not have been “uniquely challenging or difficult for one of ordinary skill in the art” or “represented an unobvious step over the prior art” (see Leapfrog Enters., Inc. v. Fisher-Price, Inc., 485 F.3d 1157, 1162 (Fed. Cir. 2007) (citing KSR, 550 U.S. at 418-19)). A skilled artisan is “a person of ordinary creativity, not an automaton” (see KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 420-21 (2007)). An ordinarily skilled artisan “must be presumed to know something” about the art “apart from what the references disclose” (In re Jacoby, 309 F.2d 513, 516 (CCPA 1962)). We further credit Dr. Wicker that an ordinarily skilled artisan “would have understood that switch K3a can be opened or closed depending upon the desired test set-up” and “by definition, switches are controlled to be open or closed” (Ex. 1001 ¶ 90). And again, Schinabeck contemplates use of the circuitry as recited, as described in claim 10 discussed supra. We thus are persuaded that Schinabeck teaches or at least suggests limitation 1a). We are also not persuaded Petitioner used impermissible hindsight reconstruction as the circuitry elements in Schinabeck are being used as was known to be used for the purpose of “monitoring response signals during automated testing of any other circuit elements –– Petitioner is relying on closing switches in the disclosed circuity of Schinabeck (Pet. 25–27). Additionally, Schinabeck discloses coupling comparison circuits to the same response signal (Ex. 1008, 11:49–53, 12:56–13:7, 4:49–66 and thus, Patent Owner’s contention that this grouping is “not any ‘desired’ configuration for functional or parametric testing” in Schinabeck is not supported by Schinabeck’s disclosure.” slip op. at 31

“However, unaddressed is the claim’s requirement that each of the two of the plurality of mitigation techniques be automatically applied “to the at least one device.” Throughout the discussion of the limitations of claim 14, and again with respect to remaining challenged claim 19, Petitioner only describes the mitigation techniques to be taught by the application of signatures to the intrusion detector functionality and the firewalling defense system. However, Petitioner also asserts that the “plurality of devices” of the claim are the devices within the network being protected. See Pet. 26 (in arguing that Willebeek-LeMair teaches “code for: receiving information in connection with at least one of a plurality of devices,” (14.4) citing network discovery functionality to discover vulnerabilities in a scan of “machines” in protected network 14). Thus, Petitioner fails to show how Willebeek-LeMair teaches or suggests “automatically applying at least two of the plurality of mitigation techniques . . . to the at least one device,” that is, to a device in network 14.” slip op. at 20

“We regard Petitioner’s formulation of the level of skill as consistent with the prior art before us (see Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

Based on the record before us and in view of the parties’ agreement at this stage of the proceeding, we adopt Petitioner’s formulation of the level of ordinary skill in the art, with the exception of the language “at least,” which introduces ambiguity. Thus, we determine, based on the record before us, a person of ordinary skill in the art would have had a Bachelor’s degree in electrical engineering, computer science, or equivalent degree or experience, with (i) two years of experience in the design and/or development of database and record management systems or (ii) more formal education in computer science, such as a Master’s degree, without the two years of practical experience.” slip op. at 9

“[a] virtual database is a sequence of characters organized into one or more sections. Each section contains zero or more records, with each record made up of one or more fields containing information. Each section of the virtual database has an associated schema which describes the format of the records and fields. The virtual database itself has a schema which describes the format of the entire virtual database. The schema of the virtual database includes the schemas of each of the sections. A virtual database (VDB), such as initial VDB 106, is self contained and may be operated on further by other operators. A VDB is self contained, in that if a record is referred to in a field in the VDB, then the referred to record is contained in the VDB. (Ex. 1001, 3:28–42 (emphasis added).) The meaning of “virtual database” is clearly and deliberately set forth in the ’062 Patent so as to put an ordinarily skilled artisan on notice as to its intended definition.” slip op. at 13
