RulingsFinal written decision- Skill levelSkill level board ownDecided for petitioner
“Although Patent Owner points to various parts of the ’518 patent as supporting its proposal, other parts of the patent are not so limited. For example, the ’518 patent repeatedly mentions prior art patents disclosing communication techniques applied to twisted pair wiring, including discrete multi-tone (DMT) modulation and bit loading. Ex. 1001, 3:49–50, 3:67–4:2, 8:19–26. The patent further mentions that its data network overlays cable or satellite services. See, e.g., id. at 5:1–6. Thus, a POSITA would not be limited to experience only with “coaxial cables” as opposed to work involving signal processing and/or communication systems/networks more generally. The ’518 patent describes the “Technical Field” as “broadband communication networks and specifically . . . communications using coaxial cable building wiring.” Id. at 1:25–30. We find it appropriate here to use the broader statement of “broadband communication networks” as the field of a POSITA’s experience. The challenged claims of the ’518 patent relate to a “data communication network” comprising “cable wiring” with “segments of coaxial cable.” Id. at 12:16–19. This does not mean that the “cable wiring” is strictly coaxial—only that it includes segments that are. Furthermore, the ’518 patent’s teachings are applicable to any network experiencing multipath reflections which degrade the ability to achieve high data rates regardless of the media over which those signals are transmitted. Id. at 4:19–32. Consequently, we determine the skill level as follows: A POSITA would have at least a bachelor’s degree in electrical engineering, computer engineering, or a related field and two to three years of experience working in broadband communication networks. Additional education could substitute for professional experience, or vice versa. For the foregoing reasons, our adopted skill level is consisted” slip op. at 11

- Obviousness (§103) › Analogous artAnalogous artDecided for petitioner
“Kliger and Isaksson are analogous art to the ’518 patent because they are from the same field of endeavor as the patent—wired networking systems— and because they are reasonably pertinent to the problem at issue in the patent—overcoming wired-network signal impairments.” Pet. 27 (citing Ex. 1004 ¶¶ 76–80); Pet. Reply 3–12. Patent Owner disagrees with Petitioner’s contention that Isaksson is analogous art. PO Resp. 12–26; PO Sur-Reply 16–25. For the following reasons, we determine that Petitioner has shown by a preponderance of the evidence that Isaksson is analogous art to the ’518 patent because it is reasonably pertinent to the problems identified in the ’518 patent. The ’518 patent seeks to overcome channel impairments by using probe messages to characterize the communication channel and determine optimum bit loading. Ex. 1001, code (57). These impairments include signal reflections, ISI, and signal attenuation. Pet. Reply 9–10 (citing Ex. 1001, 3:5–19). Similarly, Isaksson estimates channel characteristics by periodic transmission of a base sync frame from one transceiver to another where it is compared with a reference frame. Ex. 1013, 10. Isaksson’s channel characteristics may include attenuation, phase shifting, and variance, which are similar to the problems identified in the ’518 patent. Id. Both the ’518 patent and Isaksson address the problem of ISI by using bit loading to transmit data using sub-carriers less affected. Ex. 1001, 3:5–20; Ex. 1013, 16, 35, 79. Hence, we find the problems identified in the ’518 patent and Isaksson of how to overcome channel impairments reasonably pertinent such that Isaksson is analogous art to the ’518 patent. We find unavailing Patent Owner’s arguments that the ’518 patent is specific to in-home networks with coaxial cables and splitters whereas Isaksson is restricted to twisted pair, point-to-point networks having no intervening devices and which are located outside of homes. PO Resp. 15– 20; PO Sur-Reply 21–24. Any such differences do not change the fundamental nature of the problems of noise and interference affecting these environments. Such differences go more toward the field of endeavor than the reasonable pertinence of the problems each address. See Pet. Reply 10 (citing Donner Tech., LLC v. Pro Stage Gear, LLC, 979 F.3d 1353, 1360 (Fed. Cir. 2020)). Specifically, both the ’518 patent and Isaksson address the problem of channel impairments such as interference (e.g., ISI) and noise, and use the solution of bit loading to overcome them. See, e.g., Ex. 1001, 4:42–47; Ex. 1013, 1:3–7, 6:17–20, 16:10–16, 79:5–14. Hence, we find that the ’518 patent and Isaksson are analogous art because Isaksson is reasonably pertinent to the problems addressed in the ’518 patent notwithstanding Patent Owner’s arguments. We do not reach the question of whether the two are in the same field of endeavor.” slip op. at 17
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“symbol interference, external noise, and dynamic network conditions adversely affecting home network communications. Pet. 23–24 (citing Ex. 1007 ¶ 73; Ex. 1010, 5; Ex. 1004 ¶¶ 65–68). Isaksson teaches using multi-carrier modulation, such as DMT and OFDM, to address frequency dependent loss and noise using synchronized bit-loading based on carrier SNR. Id. at 24 (citing Ex. 1004 ¶ 69; Ex. 1013, code (57), 26:4–20). We agree with Petitioner that the combination of Kliger and Isaksson amounts to the use of known techniques (Isaksson’s synchronized bit-loading) to improve similar devices in the same way (overcoming interference and maintaining connections with other modems). Id. at 26–27 (citing KSR, 550 U.S. at 415–421). We do not agree with Patent Owner’s argument that Kliger already solves the issues that Petitioner identifies such that a POSITA would not have looked to Isaksson’s synchronized bit-loading. PO Resp. 50. Petitioner has established that Isaksson’s solutions would improve Kliger’s modulation by determining the number of bits-per-carrier based on SNR, disabling noisy carriers, and synchronizing bit loading. Pet. 23–28; Pet. Reply 23–24. Hence, a POSITA would have been motivated to improve Kliger with Isaksson. See KSR, 550 U.S. at 417 (“if a technique has been used to improve one device, and a [POSITA] 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”). Patent Owner alleges that Kliger’s network is coaxial whereas Isaksson’s is point-to-point, twisted pair with no intermediary devices such as splitters which would cause the interference, noise, and attenuation that the ’518 patent addresses. PO Resp. 50–55. However, we do not agree that these alleged differences would have precluded a POSITA from making the combination of references. “Signal impairments such as reflections, noise, attenuation, and inter-symbol interference (ISI) are common challenges in nearly all communication mediums.” Ex. 1036 ¶¶ 23–27. Communication networks experience these challenges, whether point-to-point or shared, twisted pair or coaxial, in-home or out-of-home, with or without splitters. Id. As Petitioner’s expert, Dr. Williams, puts it, “a POSITA can draw from the same toolbox of known solutions to address these impairments regardless of the medium.” Id. ¶ 27. Among those solutions is Isaksson’s approach of synchronized bit-loading. Moreover, Isaksson expressly states that “[i]t should be emphasized that the present invention can be used not only with the MUSIC system as herein described, but with other multi-carrier systems employing dynamic bit loading.” Ex. 1013, 72:5–8 (emphasis added); Ex. 1004 ¶¶ 81–82. Hence, a POSITA would have been led to consider using Isaksson’s synchronized bit-loading with Kliger’s coaxial network which uses a multi-tone transmitter to determine whether to transmit power on each particular tone. See, e.g., Ex. 1007 ¶ 166; Ex. 1013 1:1–7. Further facilitating the combination is Kliger’s disclosure of using “a regular multi-tone transmitter (either OFDM or DMT) to determine whether to transmit power on each particular tone wherein tones can be silenced (which is, in effect, a form of bit-loading). See, e.g., Ex. 1007 ¶¶ 6, 166, Fig. 1; Ex. 1013, 1:1–7, 3:24–34, 4:21–25, 16:8–12. In addition, Kliger expressly recognizes and seeks to address signal impairments caused by splitters, including poor signal isolation, return loss performance, degradation at higher frequencies, and inter-symbol interference due to reflections (the same problems the ’518 patent addresses). Ex. 1007 ¶¶ 61, 73. Accordingly, a POSITA would have been motivated to combine teachings of Kliger and Isaksson. Patent Owner argues that Petitioner did not explain how a control channel would exist across a coaxial splitter’s multipath signal. PO Resp. 56–58 (citing Pet. 26; Ex. 1013, 73:4–15, 74:22–31, Fig. 33; Ex. 2002 ¶¶ 147–148). Patent Owner does not explain why it would be necessary to use Isaksson’s control channel in Kliger, particularly when Kliger has its own control channel. Ex. 1007 ¶¶ 63–64, 166. Patent Owner’s argument amounts to bodily incorporation of Isaksson in Kliger, which is not a proper approach to obviousness. See In re Keller, 642 F.2d 413, 426 (CCPA 1981). We further disagree with Patent Owner’s argument that Isaksson’s base sync frames (equivalent to the claimed probe messages) would not function in Kliger’s network. PO Resp. 58–60 (citing Pet. 26; Ex. 1007 ¶¶ 55–57; Ex. 1013, 24:8–28, Fig. 1; Ex. 2002 ¶¶ 149–154). Patent Owner’s arguments are directed toward an embodiment of Isaksson that Petitioner did not cite in its Petition. Pet. Reply 26. In any case, Patent Owner does not establish that using Isaksson’s base sync messages in Kliger’s system would have been beyond a POSITA’s skill. Id. at 25–26 (citing Ex. 1036 ¶¶ 90– 93). Patent Owner argues that Isaksson’s base sync frames would alter the principle of operation of Kliger because Kliger requires all devices to transmit fixed constellation size based on overall network characteristics rather than specific channel characteristics between each HNM. PO Resp. 60–63 (citing Ex. 1007, code (57), ¶¶ 40–44, 91, 99, Fig. 1; Ex. 1013, 3:24– 27, 20:24–25, 26:14–17, 78:5–79:5, Fig. 36; Ex. 2002 ¶¶ 155–157). Patent Owner has not established, however, that fixed constellation size is a “principle of operation” of Kliger, or that Kliger would require substantial reconstruction or redesign to incorporate variable constellation sizes. See In re Ratti, 270 F.2d 810, 813 (CCPA 1959). We agree with Dr. Williams that a POSITA would have sought to improve Kliger with Isaksson’s techniques. Ex. 1036 ¶ 95.” slip op. at 19

“Considering the parties’ proposals and the record evidence, we adopt the following level of ordinary skill in the art, which we apply in this Decision: A POSITA would have a bachelor’s degree in electrical engineering, computer engineering, or a related field, and two to three years of experience with broadband communication networks. Additional professional experience could substitute for education, and additional education could substitute for professional experience. We find Patent Owner’s proposal to limit a POSITA’s education and experience to “broadband networks over coaxial cables” too narrow. Although Patent Owner points to various parts of the ’249 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 LAN wiring, twisted pair, and satellite as communications media that can be used. See, e.g., Ex. 1001, 1:11–16, 2:65–66, 3:9–37, 3:58–61, 7:4–5. In addition, while Patent Owner indicates that the ’249 patent addresses “the problem of tap port-to-port isolation and providing a suitable signal path for terminal-to-terminal communication in a coaxial cable wired building” (id. at 3:4–7), we see no reason why this problem and the solutions proposed in the ’249 patent (using frequency bins to bit load or equalization) would not be equally applicable to other kinds of communication media. Therefore, we find our adopted skill level to be consistent with the problems and solutions identified in the ’249 patent and 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. Ex. 1002 ¶¶ 17–18; Ex. 2007 ¶¶ 57–58.” slip op. at 14

“On this record, we find that Petitioner has shown by a preponderance of the evidence that Jacobsen was publicly accessible more than one year before the ’249 patent. Jacobsen is thus § 102(b) prior art. By its own terms, Jacobsen indicates that it is one of the National Cable Television Association (“NCTA”) 1994 Technical Papers related to the 43rd Annual NCTA Convention and Exposition, New Orleans, Louisiana, May 22–25, 1994. Ex. 1007, 1–3, 6. This event and related papers address topics that would have interested persons in the field as we define their skill level. See § II.B, supra. The listing of Jacobsen as one of the papers covered in the event schedule suggests that POSITAs attending this event would have known of and had access to Jacobsen. Ex. 1007, 2–3. In fact, Mr. Bates, Patent Owner’s own expert witness, who was at least a person having ordinary skill in the art, testified that he was aware of Dr. Jacobsen’s work in the late 1990s, well before the priority date. See Ex. 1029, 52:10– 55:1. Therefore, a person having ordinary skill in the art would have known of Jacobsen before the priority date. See Nobel Biocare Servs. AG v. Instradent USA, Inc., 903 F.3d 1365 (Fed. Cir. 2018) (holding that a catalog distributed at a conference was a printed publication); In re Klopfenstein, 380 F.3d 1345 (Fed.

Cir. 1985) (holding that a paper disseminated to six people of ordinary skill in the art and discussed with between 50 and 500 people skilled in the art was a printed publication). The evidence further demonstrates that Jacobsen was acquired by the Linda Hall Library, Kansas City, Missouri, on September 19, 1995 and made available to the public shortly afterward. Ex. 1022 ¶¶ 4–5, 13; Ex. 1031 ¶¶ 7, 17. Availability to interested persons more than one year before the ’249 patent is corroborated by other publications of Jacobsen, as well as Dr. Acton’s testimony. Ex. 1022 ¶¶ 10–13; Ex. 1031 ¶¶ 10–12, 16–17; Ex. 1003 ¶ 247. We do not agree with Patent Owner’s arguments against Jacobsen. There is no requirement in the law for Ms. Munford to be an interested person or POSITA in order for her to testify about how the Linda Hall Library acquired and cataloged Jacobsen so that interested persons would be able to access it. Her testimony relates to the public accessibility of Jacobsen, not its technical content. See, e.g., Ex. 1031 ¶ 6. She need not qualify as a POSITA to offer this testimony. Ms. Munford further testified that MARC records are used by the public to discover materials within a library’s collection, and that library users, which would include interested persons and POSITAs, do not require knowledge of how MARC records are maintained in order to use them. Ex. 1031 ¶ 8. And even if MARC records are editable, as Patent Owner argues, Patent Owner has not shown that the MARC record for Jacobsen was altered, and Ms. Munford states that such an alteration would have been unusual practice for a library.

“We do not agree with Patent Owner that Amit is restricted to “single frequency” modulation. PO Resp. 52–56. As Petitioner notes, Amit describes that its HCNM modem uses a channel (e.g., DOCSIS) containing two sub-channels for upstream and downstream signals. Pet. 24 (citing Ex. 1005, 15:18–28). This meets Patent Owner’s definition for multicarrier communications as multiple subcarriers to provide communications of a single channel. PO Sur-Reply 6. We further note that the claims do not recite “multicarrier communications” so the distinction Patent Owner attempts to draw is not supported by commensurate language in the claims. See In re Self, 671 F.2d 1344, 1348 (CCPA 1982) (limitations not appearing in a claim cannot be relied upon for patentability). Furthermore, even if Amit were restricted to single carrier modulation, as Patent Owner argues, Petitioner relies on Jacobsen for its teaching of multicarrier modulation. Pet. 62–66; PO Resp. 52–56. In essence, Patent Owner attacks Amit individually and does not properly consider how a POSITA would have understood the combined teachings of Amit and Jacobsen. “Non-obviousness cannot be established by attacking references individually where the [challenge] is based upon the teachings of a combination of references.” In re Merck & Co., 800 F.2d 1091, 1097 (Fed.

Ms. Munford further testified that MARC records are used by the public to discover materials within a library’s collection, and that library users, which would include interested persons and POSITAs, do not require knowledge of how MARC records are maintained in order to use them. Ex. 1031 ¶ 8. And even if MARC records are editable, as Patent Owner argues, Patent Owner has not shown that the MARC record for Jacobsen was altered, and Ms. Munford states that such an alteration would have been unusual practice for a library.

“the Final Written Decision for “not clearly explaining its holding or rationale regarding motivation to combine and whether the proposed combination teaches the final limitation of claim 1: transmitting an indication of the first host responsive to the correlating.” Palo Alto Networks, 122 F.4th at 1384. In the opinion, the Federal Circuit explained that the Final Written Decision “never made a clear finding on whether a person of ordinary skill in the art would have been motivated to modify Paxton by adding Sutton’s step of transmitting a notification of malicious activity after Paxton’s correlation step,” as proposed by Petitioner.

“The parties’ dispute on this issue turns on claim construction. Petitioner’s approach requires we read “accumulation” as updating transmission power for each received TPC command. That is consistent with some aspects of the ’153 patent’s description. See Ex. 1001, 9:29–42 (“[S]tep is the magnitude of the amount added to an accumulator upon receipt of each TPC command. . . . [T]he transmit power PTx(k) may be updated each time a new TPC command is received.”). Patent Owner’s approach requires only that TPC commands cumulatively affect transmission power. That also appears consistent with the ’153 patent’s description. See id. at 9:35–36 (“The transmit power PTx(k) may be updated for every frame period.”). Based on those disclosures, it appears that the Specification supports Patent Owner’s broader construction. We need not resolve the “accumulation” claim-construction dispute at this stage, because Petitioner’s Zeira-based ground justifies institution, as discussed below. The parties should address the proper construction for “TPC command accumulation” in the instituted trial.” slip op. at 8

“We do not agree with Patent Owner that the present record shows Andersson’s and Khan’s approaches couldn’t or wouldn’t be combined in the manner Petitioner asserts. Although shared-channel applications may have motivated Khan’s approach, it seems that scheduling grants applicable to a particular UE could be transmitted to that UE along with Andersson’s TPC commands. Thus, Patent Owner does not undermine Petitioner’s prior-art combination on the present record. The additional record developed through trial may ultimately support Patent Owner on this point, but at present, this argument does not justify denial of institution. Patent Owner additionally takes issue with Petitioner’s asserted benefits such as “allowing for a larger number of active wireless units,” reducing complexity, and reducing latency. Prelim.

“Patent Owner submits that the asserted combination is unworkable and that skilled artisans would not have made it because Andersson’s DPCCH is a dedicated channel sent to a single UE, whereas Khan’s TPC commands and scheduling grants are sent using a shared channel—“a channel that is shared by the UEs attached to a particular base station.” Prelim. Resp. 20. Because Khan’s TPC commands and scheduling grants “are intended for different UEs that share the channel,” unlike Andersson’s TPC commands in a dedicated channel, Patent Owner asserts, “the two frame structures cannot be combined in the manner Petitioner suggests.” Id. at 20–21.

“The definition of a person having ordinary skill in the art that we adopted in the Institution Decision is supported by the testimony of Dr. Akl. Ex. 1003 ¶ 22. Patent Owner states that it agrees with that definition, while also proposing a broader definition that includes those with other qualifications. PO Resp. 2. Although Patent Owner argues that “the supporting evidence [for its addition] is broadly present in the case, namely, in the Patent-in-Suit and the associated intrinsic evidence” (PO Sur-reply 3 n.6), Patent Owner does not direct us to any specific portion of the record. See United States v. Dunkel, 927 F.2d 955, 956 (7th Cir. 1991) (“Judges are not like pigs, hunting for truffles buried in briefs.”); DeSilva v. DiLeonardi, 181 F.3d 865, 866–67 (7th Cir. 1999) (“A brief must make all arguments accessible to the judges, rather than ask them to play archaeologist with the record.”). Additionally, while Patent Owner proposes expanding the definition, Patent Owner has not explained how that difference would materially affect the outcome of this proceeding. PO Resp. 2; PO Sur-reply 3 & nn. 4, 6. Dr. Akl uses Petitioner’s definition in his testimony (Ex. 1003 ¶¶ 22, 23) and Patent Owner makes no argument regarding how, if we adopted Patent Owner’s broader definition, Dr. Akl’s conclusions would be affected. Patent Owner’s use of its definition does not describe the conclusions of one “educated in general physics” differently to one of ordinary skill as defined by Petitioner. PO Sur-reply 6. Patent Owner does not present declarant testimony regarding knowledge of one of ordinary skill in the art under any definition.3 For these reasons, we maintain the definition of a person having ordinary skill in the art we adopted in the Decision on Institution: a person having ordinary skill in the art would have had experience in the hardware and software used in the field of securely transmitting and processing authorization requests over wired and wireless networks, such as requests for the processing of financial transactions, and a bachelor’s degree in computer science, computer engineering, electrical engineering, or a related study, and would have one or two years of experience with wired and wireless 3 See infra footnote 5. as financial transactions.

“Having analyzed the arguments and the evidence cited by Patent Owner, we do not agree. We begin with the claim language, which does not further describe the two transmission channels, let alone contradict the plain meaning. Ex. 1001, 6:5–19. Dependent claims also shed no additional light. Certain claims further specify transmission-channel-related requirements: that the first transmission channel be “selected from the group consisting of wireless and landline channels” (claim 7); that the request received via the first transmission channel be “provided via the Internet” (claim 5); or that the notifying step (via a second transmission channel) comprise “sending an SMS message to the customer (claim 2). Id. at 6:20–21, 6:28–29, 6:33–35. No claims further restrict claim 1 by describing both transmission channels. Id. Claim 9 requires that the notification be “substantially concurrent,” but nothing in the record establishes that substantially concurrent authorization and notification would require non-overlapping transmission channels, or that an overlap in the transmission channels, even if it did “encumber” the authorization process with the notification process, would prevent the processes from being “substantially concurrent.” While Patent Owner presents arguments about “the gist” of the invention (PO Resp. 4) and describes “an immediate separation of the two processes” as being disclosed by Figures 1 and 2 of the ’564 patent’s specification, we do not see in the specification an indication of a special disavowal of a broader scope. See Phillips, 415 F.3d at 1316–1317; PO Resp. 13 (“The specification of the ‘564 Patent does not express any intent to impart a novel meaning to the term distinct.”). Although we agree with Patent Owner that Figure 1 illustrates transmission channels that are separate and non-overlapping, we do not see any indication that this is more than a description of preferred embodiments or that there was a limitation of the invention to these embodiments, and our reviewing court “has repeatedly ‘cautioned against limiting the claimed invention to preferred embodiments or specific examples in the specification.’” Williamson v. Citrix Online, LLC, 792 F.3d 1339, 1346–47 (Fed. Cir. 2015) (quoting Teleflex, Inc. v. Ficosa N. Am. Corp., 299 F.3d 1313, 1328 (Fed. Cir. 2002)).
