    “information related to a shared web browsing interaction” is interchangeable with “web browsing interaction data” and, as a result, this portion of the specification should limit the claim term. PO Resp. 18–19 (quoting Ex. 2004 ¶ 40). The quoted portion of Mr. Friedman’s testimony, however, addresses other terms in the specification and not “information related to a shared web browsing interaction.” PO Resp. 18–19 (quoting Ex. 2004 ¶ 40). As such, the testimony cited by Patent Owner does not support Patent Owner’s position. Accordingly, we determine that the patentee has not acted as a lexicographer to set forth a definition of “web browsing interaction data” in the written description. c. Plain and Ordinary Meaning Because the patentee has not acted as a lexicographer to set forth a definition of “web browsing interaction data,” we look to the plain and ordinary meaning of the term. See Edwards Lifesciences LLC v. Cook Inc., from the ordinary meaning will be adopted “when the patentee acted as his own lexicographer and clearly set forth a definition of the disputed claim term in either the specification or prosecution history” (internal quotation marks omitted)); Pet. Reply 5 (Petitioner arguing that “web browsing interaction data” should be afforded its plain and ordinary meaning) (citing Ex. 1034 ¶ 13). Notably, both Dr. Lieberman and Mr. Friedman agree that the plain and ordinary meaning of “web browsing interaction data” is sufficient to inform how one of ordinary skill would have understood the term. Ex. 1034 ¶ 13 (Dr. Lieberman testifying: “The plain meaning of ‘web browsing interaction data’ is data related to web browsing interactions. No additional definition or limitation is required in my opinion, nor is there any special or specific meaning given to the term in the specification of the ’145 patent.”); Ex. 1033, 171:5–16 (Patent Owner’s expert, Mr. Friedman, testifying that “the plain and ordinary meaning is sufficient.”). According to Petitioner, the plain and ordinary meaning is “data related to web browsing interactions.” Pet. Reply 5 (citing Ex. 1034 ¶ 13); Ex. 1034 ¶ 13 (“The plain meaning of ‘web browsing interaction data’ is data related to web browsing interactions.”).

    “Accordingly, we conclude that the plain language of the claims does not require “web browsing interaction data” to be limited to data describing interaction performed on a website by a host device. We turn to the specification because the meaning of “web browsing interaction data” is informed “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. The written description does not provide a definition or clear meaning for “web browsing interaction data.” Patent Owner acknowledges the term is not expressly used in the written description. PO Resp. 17. Patent Owner, however, identifies “information related to a shared web browsing interaction” as a term that is interchangeable with “web browsing interaction data.” PO Resp. 18, 29. We recognize the specification term “information related to a shared web browsing interaction” is substantially similar10 to Petitioner’s proposed plain and ordinary meaning of “web browsing interaction data” as “data related to web browsing interactions.” 11 Patent Owner identifies three passages that each describe the present invention as receiving information related to a shared web browsing interaction performed by a host device and performing the shared web browsing interaction based on the received information. PO Resp. 17–18 (block quoting Ex. 1001, Abstract, 3:10–24).

    “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).

    “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.

    “When deciding whether issue preclusion applies, we consider whether: (1) a prior action presents an identical issue; (2) the prior action actually litigated and adjudged that issue; (3) the judgment in that prior action necessarily required determination of the identical issue; and (4) the prior action featured full representation of the estopped party. VirnetX Inc. v Apple, Inc., 909 F.3d 1375, 1377 (Fed. Cir. 2018) (citing Stephen Slesinger, Inc. v. Disney Enterprises, Inc., 702 F.3d 640, 644 (Fed. Cir. 2012)). To the extent Petitioner asks us to consider the 01473 IPR institution decision for issue preclusion, we do not. In that decision the Board reached a finding based on the institution standard (showing of a “reasonable likelihood that the petitioner will prevail,” 35 U.S.C. § 314(a)) rather than proof by a preponderance of the evidence, which is before us now (35 U.S.C. § 316(e)). Ex. 1016. Thus, issues before us here were not presented and adjudged in that institution decision. Regarding the 01473 IPR adverse judgment decision, that decision did not require determination of any issues before us, as that decision was based on Patent Owner canceling the challenged claims rather than any determination regarding unpatentability that had been shown by a preponderance of the evidence. Ex. 1014. 2. Collateral Estoppel With Respect to the 00571 IPR We find and determine that the final written decision in the 00571 IPR, and the Federal Circuit’s CommScope decision affirming that decision, satisfies the conditions for applying collateral estoppel because the 00571 discloses materially the same claim limitations7 challenged here, and Patent Owner had full representation throughout the proceedings. Setting aside the factors of issue preclusion for a moment, our reviewing court’s affirmance of our final written decision in CommScope is persuasive authority that supports our prior construction of “packetizing” and Petitioner’s showing that Wu teaches the disputed packetizing limitations under that construction. In addition, issue preclusion prevents Patent Owner from re-litigating the issue of whether Wu teaches materially the same disputed limitation. See Pet.

    “a . . . set of radio resources” is not limited to and does not necessarily include configuration information that is required to or used to reconfigure remote radio units. As Petitioner argues, there does not appear to be any indication in the specification and other intrinsic evidence that “digital representation” should be given more than its ordinary meaning, or that an underlying construction of “radio resources” would not be applied to this claim term, which explicitly includes “radio resources.” Pet. Reply 9–10 (citing Ex. 1001, representation” in the specification of the ’499 patent). Our construction is further supported by the language of the claims, which requires that each “set of radio resources” is “for transmission at an antenna of the first remote unit.” Ex. 1001, 14:17–19, 14:22–24, 15:3–5, 15:8–10, 16:6–8, 16:11–13. With respect to the “digital representation” of “set[s] of radio resources,” the specification of the ’499 patent describes that in the downlink (base station to DRU antenna) path for data, RF signals received at the DAU from base station(s), are down-converted, digitized, and further processed resulting in “independently serialized, parallel data streams” that are delivered to DRUs. Ex. 1001, 4:63–5:12. Petitioner contends that this description of delivery of a digitized version of an RF signal to DRUs describes the sending/transmission of a digital representation of the radio. Pet. 9–10. While Patent Owner appears to argue that a “digital representation” of a radio resource would be only an “identifier” of, e.g., an RF carrier (PO Resp. 18), this does not appear to be supported by the specification or the cited testimony of Dr. Chrissan. We do not see a reason to relate “digital representation of . . . a set of radio resources” in the claims to the description in the ’499 patent specification of the remote configuration of DRU parameter settings via the DAU, including detecting or determining radio resources assigned to a DRU and configuring the DRU, turning on and off individual carriers transmitted and received by a DRU.

    “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

    “arguments. 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. Petitioner points out that Dr. Wood cited examples from Exhibits 1006, 1033, 1046, and 1050 pertaining to “configuration errors,” and those citations are not limited to those that would have been internal to the configurator. Pet. Reply 8 (citing Ex. 1002 ¶¶ 40–41, 48–49).

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “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. We determine this asserted level of skill comports with the qualifications a person would have needed to understand and implement the teachings of the ’479 Patent and the prior art of record (cf. Okajima, 261 F.3d at 1355 (the prior art itself may reflect an appropriate level of skill in the art)).” slip op. at 10

  • Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notPreamble limitingDecided for patent owner

    “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

  • Obviousness (§103) › Graham factors (scope of art, differences, level of skill)UnpatentableUnpatentable

    “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

    “Patent Owner, in focusing on this portion of the ’226 patent disclosure, does not adequately explain why buffer cells and configuration memory cells must be included in the proper construction of “wide configuration data port,” and seeks to import a functional description of the use of a wide configuration data port (“that allows parallel updating of logic cells in a programmable array through use of buffer cells”) into the claim construction. PO Resp. 15–17; PO Sur-reply 2–4. While the discussion in the ’226 patent describes an example of a wide configuration data port used in a specific way that aligns with Patent Owner’s proposal (Ex. 1001, 4:45– 59), other examples of the use of a wide configuration data port are included (id. at 4:59–65), and therefore we do not agree that one of ordinary skill would understand this use to be part of the construction of the term. We agree with Petitioner that the proper construction of the term does not require buffer cells. See Pet. Reply 4–6. Rather, we note that the specification of the ’226 patent contrasts loading of data to an FPGA in a byte serial fashion through a narrow port, which “results in [] long reconfiguration times,” with the use of a wide configuration data port, and therefore we determine that one of ordinary skill would understand the wide configuration data port, in contrast to the byte serial “relatively narrow” port, to include parallel connections between cells in the dies. See Ex. 1001, 4:3– 9. This additionally is consistent with certain arguments by Patent Owner, for example in the Patent Owner’s Response, which opens with a discussion of the “innovative” processor’s arrangement of die-area contacts, such as through-silicon vias, “into a wide configuration data port” and we find that description more consistent with the proper construction of this term. PO Resp. 1–2; see also PO Sur-reply 2–3 (“Arbor’s experts have been consistent that the word ‘wide’ in this term requires a sufficient number, and appropriate arrangement, of connections between the memory die and the programmable array to permit parallel updating of the array.”)” slip op. at 15

  • Claim Construction › Functional claiming / §112(f) means-plus-function › Corresponding structure / algorithm (indefinite if none)Decided for petitioner

    “While corresponding structure need not include all things necessary to enable the claimed invention to work, it must include all structure that actually performs the recited function.” Default Proof Credit Card Sys. Inc. v. Home Depot U.S.A., Inc., 412 F.3d 1291, 1298 (Fed. Cir. 2005). Conversely, structural features that do not actually perform the recited function do not constitute corresponding structure and thus do not serve as claim limitations. Chiuminatta Concrete Concepts, Inc. v. Cardinal Indus., Inc., 145 F.3d 1303, 1308–09, (Fed. Cir. 1998); see B. Braun Med., Inc. v. Abbott Labs., 124 F.3d 1419, 1424 (Fed. Cir. 1997) (“[S]tructure disclosed in the specification is ‘corresponding’ structure only if the specification or prosecution history clearly links or associates that structure to the function recited in the claim.”). Patent Owner’s arguments regarding buffer cells connected with memory configuration cells using die-area interconnections requires that the buffer cells be located on a different die than the memory configuration cells, but the ’226 patent discloses only that “[t]he buffer cells 88 are preferably a portion of the memory die 66” and not that they always are on the memory die, and also that the significantly increased number of connections to the cache memory die may allow the cache memory die to replace configuration bit storage on the FPGA die. Ex. 1001, 4:50–54, 4:59–63. Thus, we decline to require in the corresponding structure that buffer cells or configuration memory are included on any die element. Rather, we find that what is disclosed as actually performing the recited function of “reconfiguring the programmable array within one clock cycle” is “a wide configuration data port and contact points formed throughout the area of the first integrated circuit die element and another integrated circuit die element.” The support for this is found in the ’226 patent’s comparison of the long reconfiguration times through a narrow port (Ex. 1001, 4:3–9) with the time to reconfigure through a wide configuration data port with a significantly increased number of connections (id. at 4:45– 65), and the implementation of this in a module that has multiple dies “which have a number of corresponding contact points, or holes, 70 formed throughout the area of the [die] package” (id. at 4:9–20). The use of a wide configuration data port, as per our construction, implicates two die elements. This was reflected in our preliminary claim construction, for which the corresponding structure described “contact points distributed through the first integrated circuit die element and the third integrated circuit die element.” Dec. on Inst. 29. As the function is “reconfiguring the programmable array within one clock cycle,” one of the die elements is the first integrated circuit die element, which includes the programmable array. slip op. at 19
