Even if Ingle falls short of teaching structured application for its capacitor’s cathode, as Patent Owner argues, that does not undermine Petitioner’s challenge because Petitioner proposes using Hasei’s structured application (i.e., a droplet discharge device) to form the cathode of Ingle’s capacitor. See Pet. 24–25. Patent Owner’s additional argument that “Hasei contains no discussion of forming capacitors” (PO Resp. 36; see PO Sur-reply 17–18) is similarly flawed—it attacks Hasei individually, while ignoring Ingle’s capacitor teaching.

    “Based on the information presented, we find Petitioner has the better position. Patent Owner admits that joint vaporization means “two materials vaporize together.” Reply 21 (quoting Resp. 54). As Petitioner argues, “This is what Ma discloses.” Id. We agree with Petitioner that Ma describes a “two-component” electron transport layer having a “thickness with one value.” Id.; see Ex. 1007, 811 (reporting a “co-deposited” application of “BPhen:LiQ” that is “50 nm thick”). Ma’s disclosure, thereby, strongly “indicates that the two components were vaporized together––as opposed to creating a ‘macroscopically homogenous form’” prepared by sequentially vaporizing the individual components as Patent Owner “hypothesizes.” Reply 21 (citing Ex. 1020 ¶¶ 42–44; Ex. 2041 ¶¶ 155–157); see Resp. 54– 55; see also Ex. 1007, 811 (Ma’s description of its device fabrication, appearing in the third paragraph of the experiments section). Petitioner further advances evidence that “[p]reparing a layer that is ‘macroscopically homogeneous’ but potentially microscopically heterogeneous,” as Patent Owner postulates, “would introduce excessive variability and render the data noncomparable and unreliable, thus undermining the experiment’s purpose.” Reply 21 (citing Ex. 1020 ¶ 44); see Resp. 54–55. Patent Owner presents no counterargument or evidence that is persuasive to undercut Petitioner’s reasoning or evidence on that point. See Sur-reply 19–22.

Here again, Petitioner’s evidence on point stands uncontested. See Sur-reply 19–22 (declining to contest that point). On this record, therefore, we agree with Petitioner that, as to the relevant disclosure in Ma, “the most natural interpretation of ‘co-deposition’ for forming a layer, particularly when there is nothing to indicate that the materials” are “vaporized sequentially,” is that the materials are co-deposited by joint vaporization. Reply 22 (citing Ex. 1020 ¶ 46–51). We further agree that, “[u]nder a preponderance standard, Ma’s disclosures are sufficient to render joint vaporization at least obvious.” Id.

Xiao teaches that server 118 generates commands for command codes that exist and are settable in the vehicle. Ex. 1010 ¶¶ 102– 103. As such, if there is no corresponding automobile setting, then Xiao’s server would not list those command codes for retrieval and would not send a command based on that retrieved command code to control the automobile systems to achieve the operator’s desired settings because that command code is not in the database. Our understanding of Xiao is further supported by Dr. Almeroth’s testimony: By listing them in the table of automobile command code information 606, Xiao shows that there are particular settings compatible with particular automobiles and particular desired settings. Thus, Xiao demonstrates the necessarily present characteristic that certain settings (e.g., commands) are compatible with certain automobiles. Ex. 1009 ¶ 96 (emphases added). We note that Dr. Malek further explains “the nonsensical result achieved by the combination would be that Xiao’s server, at best, in response to the command request issued by the operator, could ‘look up’ a command code to apply a vehicle-specific setting to that automobile 112, only to find that there is ‘none.’” We agree with Dr. Malek that there is a “None” command code in Xiao’s database when Xiao’s database already stores settings that are known to be settable in a specific vehicle per the operator’s preferences.

    “Patent Owner’s proposal to limit a POSITA’s education and experience to “broadband networks over coaxial cables” is too narrow. Although Patent Owner points to various parts of the ’518 patent as supporting its restrictive proposal, other parts of the patent are not so limited. For example, the patent’s technical field and summary are not limited to coaxial cable, and the patent discusses twisted pair wiring and satellite communications as media that can be used. See, e.g., Ex. 1001, 1:27–29, 3:33–35, 3:49–50, 3:67–4:3, 5:61–6:3, 8:20–23, 9:28–33. Accordingly, we adopt the following level of ordinary skill in the art for use in this Decision: A POSITA would have a bachelor’s degree in electrical engineering, computer engineering, or a related field, and two to four years of experience with broadband communication networks. Additional professional experience could substitute for education, and additional education could substitute for professional experience.

  • Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageTerm construed board ownDecided for petitioner

    “We agree with Petitioner that the ’690 patent does not limit the term “probe” to channel assessment. Pet. Reply 2–4. Reviewing the intrinsic evidence, the “Technical Field” of the ’690 patent states that “some embodiments relate to channel assessment probes,” implying others do not. Ex. 1001, 1:13–14. The ’690 patent further states that “receiver determined probes may be used in a variety of applications” including to “discover hidden nodes” and “off-site network diagnosis.” Id. at 2:20–27. In addition, the ’690 patent states that probes may be used for “network maintenance procedures,” to “replicate a potential problem, reach or discover a distant or previously undetected node on the network, or assist with network admissions procedures.” Id. at 4:25–38. Turning to the claims of the ’690 patent, the evidence of record does not establish that the independent claims recite anything unique or specific to channel assessment (although their scope covers that purpose). Furthermore, dependent claim 7 of the ’690 patent recites that the “probe” is used to diagnose a network problem, and dependent claim 13 recites that the “probe” is used to identify a hidden node. Restricting the independent claims to probes used solely for channel assessment would be contradictory to these dependent claims. Littlefuse, Inc. v. Mersen USA EP Corp., 29 F.4th 1376, 1380 (Fed. Cir. 2022) (construction of term in independent claims should not render dependent claims superfluous or lacking scope).” slip op. at 20

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Term construed board ownDecided for petitioner

    “We agree with Petitioner that a “physical layer probe” is “a probe that relates to the physical layer.” The term does not appear per se in the specification of the ’960 patent, nor in the prosecution history, but only in claims 9, 17, and 19. However, the term “physical layer” is well-known and is the first layer in the Open Systems Interconnection (OSI) network model. See, e.g., Ex. 1021, 35–40, 69; Ex. 1002 ¶¶ 49–50. The physical layer is used to transmit digital bits over a network, and defines the timing, mechanical, and physical network characteristics required for transmitting the data bits. Hence, a “physical layer probe” is a probe that relates to the physical layer. We need not, and do not, construe the term further to resolve the parties’ dispute. See Realtime, Vivid Techs., supra. Having decided proper constructions for the disputed terms, we proceed in our analysis to consider the parties’ arguments concerning the challenge grounds. In the following sections, we apply the plain meaning of the claim terms, and as necessary, specify what the plain meanings are.” slip op. at 23

    “C. Level of Ordinary Skill in the Art Petitioner contends as follows: A POSITA8 would have had a bachelor’s degree in electrical engineering, computer engineering, or a similar discipline, and three to four years of experience working in signal processing and/or communication systems/networks. Additional education may substitute for experience, and significant work experience may substitute for formal education. Pet. 6 (citing Ex. 1002 ¶¶ 115–120). Patent Owner does not dispute Petitioner’s proposed level of skill in the art. We adopt and apply Petitioner’s proposed skill level because it is consistent with the problems and solutions identified in the ’690 patent and the prior art references asserted by Petitioner. In addition, we find the adopted skill level consistent with the education and experience that a POSITA would have had. See In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

Because the word “means” does not appear in the claims of the ’826 patent, there is a presumption that the claims do not recite means-plus-function limitations under § 112 ¶ 6. Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1348 (Fed. Cir. 2015) (en banc in relevant part).

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

    “Although Patent Owner argues that adding Konstaninos’s multi- channel functionality to Kamieniecki’s single-channel device would increase costs and complexity, Patent Owner overlooks that multi-channel functionality would also increase the STB’s capabilities. In any case, “a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate a motivation to combine.” General Elec. Co. v. Raytheon Tech. Corp., 983 F.3d 1334, 1351 (Fed. Cir. 2020) (citing Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006)). Furthermore, Petitioner presents preponderant evidence that the market demand was such that customers would have desired an STB with multi-channel functionality even though it would cost more than a basic STB. Pet. Reply 6–8 (citing Ex. 1010 ¶¶ 1, 11, 16, 102–104; Ex. 1032 ¶¶ 5–6; Ex. 1033, 27:6–29:23; Ex. 2013 ¶¶ 70, 108). Konstantinos expressly teaches that the “evolving market for data and programming services will demand that receivers have the capability of multi-channel tuning.” Ex. 1010 ¶ 1. Petitioner has thus established that there was market demand that would have led a POSITA to improve Kamieniecki with Konstantinos’s multi-carrier capability. See KSR, 550 U.S. at 418 (“Often, it will be necessary for a court to look to interrelated teachings of multiple patents; the effects of demands known to the design community or present in the marketplace; and the background knowledge of a [POSITA], all in order to determine whether there was an apparent reason to combine the known elements in the manner claimed by the patent at issue.” (emphasis added)). Moreover, we agree with Petitioner that Konstantinos addresses the cost and complexity issues that Patent Owner asserts are problematic. Pet. 35–36; Pet. Reply 8–9 (citing Ex. 1010 ¶¶ 102, 105–106). For example, Konstantinos teaches that breaking up the original signal into smaller subsignals decreases the required sampling rate for each band since interleaved lower-rate samplers can be used, which reduces power consumption and interference, and enables conventional digital channel selection methods to be used for fine selection of one channel from a band of channels. Ex. 1010 ¶¶ 102, 104105. In addition, Konstantinos teaches reducing cost and complexity through a single chip solution. Ex. 1002 ¶ 150; Ex. 1010 ¶ 44. Hence, we do not see the cost or complexity issues that Patent Owner mentions as barriers that would have prevented a POSITA from making the combination. Similarly unavailing is Patent Owner’s stance that Kamieniecki is satisfactory for the applications for which it is designed such that a POSITA would not seek to improve it with Konstantinos. PO Sur-Reply 8–11. Konstantinos recognizes the market demand for multi-channel functionality, so adding this capability to Kamieniecki’s single-channel device would have been a natural thing for the POSITA to pursue in light of the advantages afforded thereby. Ex. 1010 ¶ 1; KSR, 550 U.S. at 420 (“any need or problem known in the field of endeavor at the time of the invention and addressed by the patent can provide a reason for combining the elements in the manner claimed”).” slip op. at 17
