    “D. Claim Construction We construe claim terms according to the standard set forth in Phillips v. AWH Corp., 415 F.3d 1303, 1312–17 (Fed. Cir. 2005) (en banc), i.e., as construed in a civil action under 35 U.S.C. § 282(b). See 37 C.F.R. § 42.100(b) (2020). Under Phillips, claim terms are afforded “their ordinary and customary meaning.” Phillips, 415 F.3d at 1312. “[T]he ordinary and customary meaning of a claim term is the meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention.” Phillips, 415 F.3d at 1313. “Importantly, the person of ordinary skill in the art is deemed to read the claim term not only in the context of the particular claim in which the disputed term appears, but in the context of the entire patent, including the specification.” Phillips, 415 F.3d at 1313. An inventor may rebut that presumption by providing a definition of the term in the specification “with reasonable clarity, deliberateness, and precision.” In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994). In the absence of such a definition, limitations are not to be read from the specification into the claims. In re Van Geuns, 988 F.2d 1181, 1184 (Fed. Cir. 1993).” slip op. at 11

    “Patent Owner does not directly oppose Petitioner’s definition of a POSITA. See generally Prelim. Resp. Patent Owner does, however, state that “Petitioner’s expert has proposed a definition of a POS[IT]A that does not include specific experience in the design of optical filters” and “[m]ere general experience in optical elements does not demonstrate that a POS[IT]A would have possessed the specific abilities to design a brand-new multilayer optical interference filter from scratch, or to recreate and modify the materials from Yoda, as would have been required” in the asserted combination of Pilgrim and Yoda.

Based on the present record including the disclosure in the ʼ526 patent, we apply a slightly modified version of Petitioner’s definition of the level of ordinary skill in the art that removes the qualification of “at least” and clarifies some statements.

    “of lower refractive index layers, and two specific properties: 1) that at least one of the one hydrogenated silicon layers is thicker than one of the lower refractive index layers, and 2) that the plurality of hydrogenated silicon layers have at least a specified refractive index at a given wavelength. Ex. 1001, 11:8–16. Petitioner argues that Pilgrim teaches the desirability of an optical filter stack having specific properties, and that Yoda teaches an optical filter having the claimed layers. However, even if it would have been desirable to use Yoda’s Si:H filter layers and those layers would have had the recited refractive index properties, as Petitioner asserts, Petitioner fails to show that an ordinarily skilled artisan would have obtained Pilgrim’s cited filter properties for an optical filter stack when implementing Yoda’s filter layers in Pilgrim’s optical filter stack. The optical filter that Pilgrim discloses, and that Petitioner relies on to teach the claimed optical filter properties, has a passband that “is centered on 950 nm with a full bandwidth of approximately +/-25 nm” and a “shift in [passband] center between an [angle of incidence (AOI)] of 0 degrees and an AOI of 40 degrees [that] is approximately 15 nm.” Ex. 1004 ¶ 26. Yoda is silent with regard to whether its filter layers could be used in an optical filter having a limited shift at a passband center, as disclosed by Pilgrim. As Patent Owner points out, “no reference cited [in] the Petition describes a design for any optical filter with a center wavelength shift of 15 nm over the 0° to 40° AOI range.” Prelim. Resp. 3. And Yoda does not “consider how the center wavelength would shift based on AOI.” Id. at 22. Petitioner’s assertion that optical filter properties and the filter layer properties are “routinely optimized parameters” (Pet. 24) does not adequately explain that an ordinarily skilled artisan would have implemented the filter layer properties taught by Yoda in an optical filter to obtain the properties disclosed by Pilgrim. Still further, Petitioner’s assertion about routine optimization is conclusory and is not supported by evidence. Nor is Petitioner’s argument that one of ordinary skill in the art would have had a reasonable expectation of success in “optimizing parameters” to design a filter for Pilgrim’s application supported by adequate evidence. Petitioner must show not only “that a skilled artisan would have been motivated to combine the teachings of the prior art references to achieve the claimed invention,” but also “that the skilled artisan would have had a reasonable expectation of success in doing so.” Kinetic Concepts, Inc. v. Smith & Nephew, Inc. 688 F.3d 1342, 1360 (Fed. Cir. 2012). Petitioner’s assertion that a POSITA would have expected to succeed in optimizing the parameters and designing a filter for Pilgrim’s application and to meet Pilgrim’s design goals in light of the guidance about how various processes and parameters impacted the index of refraction and extinction coefficient of Si:H and the POSITA’s ability to simulate the performance of the filter designs using the optimized materials (Pet. 22) does not address whether a POSITA would have had a reasonable expectation of success in creating an optical filter with the required properties using the filter layers described by Yoda. Petitioner has not shown a POSITA would have had the “ability to simulate the performance of the filter designs using the optimized materials.” Pet. 22. For example, Petitioner has not discussed what specific simulation techniques or tools would have been used by a POSITA. Furthermore, although Petitioner’s expert asserts the POSITA would have been led to select hydrogenated silicon as the high-refractive index material and would have further found it obvious to design the material to increase the refractive index to meet the design goals, while still maintaining a low extinction coefficient. These goals would have been achieved by tailoring the deposition processes and conditions, as well as the hydrogen content of the hydrogenated silicon material, as was known to the POSITA (Ex. 1002 ¶ 145), that statement does not explain how the tailoring the deposition processes and conditions and the hydrogen content would have led to successfully maintaining the low extinction coefficient, let alone to successfully creating an optical filter with Pilgrim’s required passband characteristics. Rather, as Patent Owner points out, the evidence cited in the record before us suggests “the design of [an optical] bandpass interference filter with a narrow bandwidth and low center wavelength shift is not trivial.” Prelim. Resp. 31 (citing Ex. 1001, Fig. 7C). Specifically, in detailing the requisite filter layers for an exemplary filter, the ’526 patent describes a filter stack of 48 layers of materials having varying thicknesses, an “[antireflective] coating includ[ing] 5 layers, and the total coating thickness [being] about 5.7 µm.” Ex. 1001, 8:1–12, Figs. 7B–7C.” slip op. at 21

    “Turning to the claim language, limitation vii recites “reconfiguring each remote radio unit by: determining a load percentage for each remote radio unit.” Claim 1 simply does not specify how to determine the load percentage for each remote radio unit and “load percentage” is a broad term. Stated differently, claim 1 does not specify the numerator or denominator to be used in determining the load percentage, but the parties agree that the numerator is the amount of load used in an RRU, as indicated above. On this preliminary record, Petitioner’s interpretation of “available capacity” as including “a single radio, a group of radios or the entire DAS system, [able to] be determined using throughput, number of connections, number of users, number of carriers, or power,” is sufficient for purposes of institution.

    “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.

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.

    “Supported by Mr. Willey’s testimony, Petitioner proposes that a person of ordinary skill in the art would have had “a Bachelor’s degree or equivalent in physics, or in a related science or engineering field, along with at least 5 years of experience in optical coating design and the manufacturing of optical filters, including various deposition techniques.” Pet. 13 (citing Ex. 1002 ¶¶ 66–68). According to Petitioner, “[a]dditional education (e.g., a Master’s degree with exposure to coating design and manufacturing) may substitute for some industrial experience in optical thin film design, and more industrial experience can substitute for a different educational background.

The questions Petitioner raises about Dr. Clemens’s qualifications were insufficiently explored on cross-examination to impeach that testimony. With respect to Petitioner’s further complaint that Dr. Clemens “did not review all the evidence in rendering his opinions, did not select the materials he reviewed, and did no independent research on the question of enablement,” we agree with Patent Owner that Petitioner cites no authority for the propositions that expert witnesses must review all exhibits or perform independent research. Sur-reply 27. Indeed, we do not find it particularly unusual for an expert witness to focus his analysis and opinions on specific issues identified by counsel, and Dr. Clemens properly discloses the underlying facts and data upon which his opinions are based.

Patent Owner does not directly address Petitioner’s proposed constructions for these terms, and appears generally to treat the terms in a manner consistent with Petitioner’s proposals.

    “One difficulty with Petitioner’s position is that it treats the refractive index and extinction coefficient as independent variables in its argument. But the prior art is clear that the adjusting the hydrogen content of Si:H to achieve a desired extinction coefficient necessarily affects the refractive index—and, as we discuss above, that such adjustments do so in a direction counterproductive to the combination of parameters the inventors sought. And we agree with Patent Owner that the refractive index and extinction coefficient “are not parameters subject to simple adjustment, but properties resulting from the parameters of the fabrication process.” PO Resp. 52 (citing Ex. 2001 ¶¶ 121–122; Ex. 1016, Figs. 2–3). At the Oral Hearing, Petitioner conceded that Patent Owner’s characterization is accurate when considering the hydrogenated silicon material. See Tr. 65:7– 12. When Petitioner refers to the refractive index and extinction coefficient as result-effective variables, Petitioner means that those parameters are variables that can affect the properties of the claimed optical filter. See id. at 64:6–65:12. As we note above, Petitioner’s argument thus presumes that the refractive index and extinction coefficient can be independently adjusted to achieve desired filter properties—but the asserted prior art teaches against such independence because the known method of adjusting the hydrogen content of Si:H not only affects both the refractive index and extinction coefficient, but does so in a manner counterproductive to the inventors’ objective.” slip op. at 35

    “In our Institution Decision, we adopted Petitioner’s definition of the level of ordinary skill in the art with minor modification (Dec. 8–9; see Pet. 20). In particular, we removed the qualifier “at least” from the education level and from the experience level, because the qualifier introduces ambiguity. Patent Owner does not dispute this determination of the level of a person of ordinary skill in the art at the time of the invention (PO Resp. 8). Thus, we determine an ordinarily skilled artisan at the time of the invention would have had (i) a bachelor’s degree in electrical engineering, computer engineering, or a related field and (ii) one year of experience with testing of electronic equipment.

    “execute a user program, the test equipment comprising” is the preamble and that it is limiting (Ex. 1003, 13:57–58; PO Resp. 9). 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

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

    “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

To aid in understanding the meaning of “a firewall-based occurrence mitigation type,” we turn to the disclosure of the ’066 Patent (see Ex. 1001).

Willebeek-LeMair further teaches, in step 312, “[t]his is reported back to the agent 126” which “responds in step 314 by reporting . . . that an attempt to exploit has occurred” (Ex. 1005 14:64–67; see Pet. 37). Willebeek-LeMair discloses the agent 126 additionally “instructs the firewalling functionality 118 in step 316 to drop the packet traffic relating to the attempted exploitation” and “in step 318 instruct[s] the firewall to block all traffic originating from the noted IP address of the attacker” (Ex. 1005 14:67–15:6, 1:7–10; see Pet. 37). Thus, because Willebeek-LeMair discloses a firewalling functionality, at this juncture, we determine Willebeek-LeMair teaches the recited “firewall-based occurrence mitigation type.” Additionally, because Willebeek-LeMair discloses instructing the firewall to block all traffic from the attacker (an occurrence mitigation action), based on the record before us, we determine Willebeek-LeMair teaches the recited “firewall-based occurrence mitigation type,” as recited in claim 1. and specifically, “a terminate action [ ] taken by the intrusion detector functionality 116 to terminate any session associated with a possible attack” (Ex. 1005, 12:40–43; see Pet. 38). Willebeek-LeMair also teaches the intrusion detector functionality generates alerts from its analysis of the network traffic content (Ex. 1005, 9:34–27, 1:7–10; see Pet. 38). Based on the record before us, we determine this intrusion detector functionality is an occurrence mitigation action that is different than the firewall-based occurrence mitigation type. Accordingly, based on the record before us, we determine Willebeek-LeMair teaches the recited “a other occurrence mitigation type,” as recited in claim 1. In combination of these two functionalities, we determine on the current record, Willebeek-LeMair teaches the recited “cause utilization of different occurrence mitigation actions of diverse occurrence mitigation types, including a firewall-base occurrence mitigation type and a other occurrence mitigation type” (see Pet. 38 (citing Ex. 1003 ¶ 97)).” slip op. at 26
