    “We agree with Patent Owner that Petitioner’s evidence in Kuntz (Ex. 1026), the Annual Report (Ex. 1028), Masuko (Ex. 1029), and Pfaff (Ex. 1034) is insufficient to show that Xirallic® Sample C was available to the public before the effective filing date of the ’861 patent. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26. Kuntz, the Annual Report, Masuko, and Pfaff may support a finding that the Xirallic® line of products was available to the public, but these documents do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public. We also agree with Patent Owner that the Technical Data Sheets (Exs. 1005–1010), Certificates of Analysis (Exs. 1011–1017), and Material Safety Data Sheet (Ex. 1025) are insufficient to show that Xirallic® Sample C was available to the public. Petitioner has not asserted, nor do we find, that any of these documents refer to or describe the lot of Xirallic® from which Sample C was taken. See Final Dec. 26–27. Regardless of how the Technical Data Sheets were used in the Opposition against the European counterpart of the ’861 patent (Exs. 1040, 1041) and during the prosecution of the application from which the ’861 patent issued (Ex. 1003, 102–104), the Technical Data Sheets do not refer to or describe the lot of Xirallic® from which Sample C was taken. Moreover, as noted by Patent Owner, the Technical Data Sheets (Exs. 1005–1010) indicate that they are “preliminary” and Petitioner has not provided any evidence that the Technical Data Sheets were ever issued to the public, as opposed to just issued internally. See PO Resp. 18–19. We also find persuasive Patent Owner’s argument that the Technical Data Sheets are preliminary because other, later-dated technical data sheets (Exs. 2012, 2013) lack the “preliminary” label and list characteristics that are different from those in Exhibits 1005–1010. See PO Resp. 19 (comparing, e.g., Ex. 1009 and Ex. 2013; Ex. 1005 and Ex. 2012). The Technical Data Sheets may support a finding that the Xirallic® products they describe existed as of the dates on the documents, but they do not support a finding that the lot of Xirallic® from which Sample C was taken was available to the public.” slip op. at 20

Cir. 2015); Inwood Labs., Inc. v. Ives Labs., Inc., 456 U.S. 844, 856 (1982)). We have reviewed the witness testimony in the record and, more particularly, Mr. Choi’s deposition answers regarding Petitioner’s purchase of the lot of Xirallic® from which Sample C came. We find that Mr. Choi’s responses cast doubt on the credibility of his declaration testimony, namely with regard to the public availability of Sample C. Mr. Choi represented that he was involved in the purchase of the lot of Xirallic® from which Sample C was taken. Ex. 2011, 48:1–23. Mr. Choi stated that he instructed Petitioner’s marketing team manager to buy the sample from a distributor of Patent Owner’s products located in Europe. Id. at 48:24–49:4. Mr. Choi stated that he has evidence of the transaction, but refused to reveal the name of the company from which Petitioner purportedly purchased the lot of Xirallic® (id. at 49:5–50:3) and refused to produce an email in his possession that would corroborate his testimony regarding Petitioner’s acquisition of the product (id. at 50:8–16, 51:10–23). Mr. Choi represented that he does not remember how much Petitioner paid for Sample B. Id. at 56:4–5. Mr. Choi admitted that the entity from which Petitioner acquired the lot of Xirallic® from which Sample C was taken is “not currently a Merck distributor” (Ex. 2011, 50:4–7) and was not “a Merck distributor at the time” that “samples B and C were purchased” (id. at 51:25–52:2). According to Mr. Choi, the company is a “former distributor” of Patent Owner’s products. Id. at 52:3–6. Mr. Choi did not know, according to his testimony, when that unnamed entity first obtained the lot of Xirallic® (id. at 52:7–10) and he stated that he did not have personal knowledge of how the entity obtained the lot of Xirallic® (id. at 52:12–19). Instead, Mr. Choi assumed the entity was “able to obtain the sample through the routine course or process” the entity uses “to take samples or get samples.” Id. at 52:12–19. Mr. Choi believed the sample of Xirallic® from which Sample C was taken was sealed when Petitioner received it because samples from dealers are sealed, and he remembered observing that the package was from a dealer. Id. at 52:24– 54:25. However, Mr. Choi admitted that he did not obtain a technical data sheet or certificate of analysis for the lot of Xirallic® from which Samples B and C were taken. Id. at 59:6–11. Mr. Choi also answered questions regarding Petitioner’s purchase of Samples D and H. Ex. 2011, 62:20–66:8, 67:7–9, 73:12–13, 73:17–22. Similar to his testimony regarding Samples B and C, Mr. Choi admitted withholding an email regarding the purchase of the lot of Xirallic® from which Sample D was taken. Id. at 62:20–63:9. Mr. Choi also admitted that he did not know how Akzo USA or Axalta obtained the Xirallic® the companies sold to him, and admitted that Akzo USA was not a distributor of Patent Owner’s products at the time Petitioner purchased the product. Id. at 63:10–66:8, 73:17–22. Mr. Choi also admitted that Petitioner did not pay Akzo USA for the lot of Xirallic® from which Sample D was taken, and did not pay Axalta for the lot of Xirallic® from which Sample H was taken. Id. at 67:7–9, 73:12–13. Although Petitioner presents declaration testimony from Mr. Choi representing that he purchased the lot of Xirallic® from which Samples B and C were taken in October 2011 (Ex. 1004 ¶ 16), Mr. Choi’s declaration testimony lacks corroborating evidence, and his deposition testimony does not support that the product was available to the public, as we found in our Final Written Decision. See Final Dec. 27–28. Notably, Petitioner produced corroborating evidence for Mr. Choi’s acquisition of Samples A, H, and I. See Ex. 1004 ¶¶ 13 (citing Ex. 1047), 18 (citing Exs. 1024, 1025). However, Mr. Choi withheld similar evidence for the Xirallic® lots from which Samples B, C, and D were taken. See Ex. 2011, 50:8–16, 51:10–23, 62:20– 63:9; Final Dec. 28. As Patent Owner argues, there is “no information to determine when a contract was established, that there was consideration for the exchange, that the product was available to be delivered when the alleged transaction took place, or even when the product was delivered. Choi has no memory of what was paid for the product.” Sur-Reply 24–25; see also PO Resp. 13–14; PO Br. Rem. 2–4.” slip op. at 34

    “Based on the evidence discussed above, we are not persuaded that Petitioner has shown by a preponderance of the evidence that Sample C was available to the public. Regardless of whether a company avoids wasting shelf life of its products (Ex. 1004 ¶¶ 15–16), there is no persuasive evidence in the record showing that the lot of Xirallic® from which Sample C was taken was released from quality control and then made available to the public by Patent Owner. Mr. Choi’s testimony shows that Petitioner obtained the lot of Xirallic® from which Sample C was taken in an atypical manner (i.e., not from Patent Owner or one of Patent Owner’s current distributors) (Ex. 2011, 49:5–50:7, 50:8–16, 51:10–23, 51:25–52:6, 52:12– 19), and there is no evidence in the record to show that the lot of Xirallic® was intended for sale, rather than for experimental use only or for some other restricted use. Accordingly, we determine Petitioner has not demonstrated by a preponderance of the evidence that Sample C qualifies as prior art against the ’861 patent, and we determine that Petitioner has not shown by a preponderance of the evidence that the ’861 patent is unpatentable over the grounds relying on Sample C.” slip op. at 38

  • 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.” slip op. at 11

    “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

    “Kliger identifies the problems of splitter reflections causing inter- 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.

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.

    “While Alden’s Figure 5 shows a sectional view of a segmented-headlight embodiment, thus depicting a single line of LEDs, that does not restrict the embodiment to a one-dimensional array.

We credit Petitioner’s expert’s testimony in this regard.

As Petitioner points out, Alden uses both intensity and a detected object’s location (including distance) to inform its response. Ex. 1005 ¶¶ 27–28. Petitioner’s expert testifies that the same physical system used to accommodate oncoming vehicles could be used to detect roadside reflectors and direct light into road curves. Ex. 2041, 78:16–80:24. Further, Petitioner’s expert testifies that skilled artisans would adjust the intensity and distance thresholds to distinguish roadside reflectors from oncoming vehicles.

Ex. 1003 ¶¶ 132–134. Although Patent Owner argues that Alden’s system could not do so while also accommodating oncoming vehicles, that position is based on the argument that “the system can’t tell the difference between signs and headlights.” PO Surreply 21–23. Patent Owner contends that “detected intensity is a function of both distance and emission intensity” so a threshold couldn’t distinguish headlights from signs. Id. at 24–25.

    “We agree with Petitioner. Alden’s system does not simply dim its headlights where it detects spots of light. Rather, it performs a multistep process in which those spots are detected, analyzed with triangulation to determine distance, and then used to determine dimming zones. Ex. 1005 ¶¶ 27–28. Alden discloses that its sensor “detects the two headlights” of an oncoming vehicle when “[e]lectrons corresponding to the position and intensity of light are categorized by a logic and CPU 71 and stored in a memory 72.” Id. ¶ 27. Petitioner’s expert noted that Alden’s description “move[s] from lights – thresholding lights to objects, and then calculate[s] distance of each thresholding object using triangulation.” Ex. 2041, 109:23–110:2. That testimony supports our view that Alden first detects lights, uses those detected lights to identify and classify an oncoming car, then dims the headlight output to prevent glare. Alden’s dimming decision particularly indicates that it classifies pairs of detected headlights as oncoming vehicles. The CPU makes “assumptions about the space that may potentially be occupied by the driver of the sensed vehicle” and identifies an area of the segmented headlight to dim that is “significantly larger than the headlight dots that were initially received.” Ex. 1005 ¶ 27. Patent Owner agrees that Alden dims “selected surrounding sectors” around detected light (PO Resp. 30), and the way Alden selects those sectors indicates that it identifies vehicles. It does not simply expand an area around each detected light; it dims an area to encompass the driver of the identified vehicle. Ex. 1005 ¶ 27, Fig. 3. By treating a pair of corresponding detected lights collectively for dimming, Alden indicates that it classifies pairs of detected lights as vehicles.” slip op. at 23

See Prelim. Reply 1–7. In particular, Petitioner raises questions with respect to the independence of Patent Owner’s evidence from the inventor testimony that evidence is intended to corroborate, as well as with respect to whether the evidence offered by Patent Owner sufficiently shows conception, reduction to practice, and reasonably continuous diligence. Id. We do not think the information of record is sufficient to antedate Krantz and Herrmann such that we should deny institution of inter partes review on that basis. First, Patent Owner’s arguments rely on the testimony of inventor Stacey C. Lum, who has not yet been subject to cross-examination. See Prelim. Resp. 35–45 (citing Ex. 2003). Second, Petitioner identifies several issues where further development of the record may be helpful. For example, Patent Owner’s asserted date of conception is associated with the date of an engineering specification included in the record as Exhibit 2011. See Prelim. Resp. 35–36 (citing Ex. 2003 ¶ 12; Ex. 2011; Ex. 2012). We agree with Petitioner (see Prelim. Reply 4–5) that it is unclear, based on the present record, whether Exhibit 2011 corroborates the testimony supporting Patent Owner’s conception date given that the present record does not establish the author of Exhibit 2011. See Ex. 2003 ¶ 22 (inventor Stacey C. Lum testifying only that “InfoExpress personnel drafted EX2011”).

See Sur-reply 4–5. Instead, we evaluate whether Dr. Howle had at least the requisite qualifications of a person having ordinary skill in the art by the time he rendered his opinions.

    “In Petitioner’s contrary view, Jarisch teaches how to move a code in a centrifugal brewing system to the bottom of the flange and how to configure a light-conductive material so that the detector’s light source will reach the bottom of the flange. Pet. 45–46; Reply 21–22 (Ex. 1003 ¶¶ 194–195; Ex. 1005 ¶¶ 82–84, Fig. 5). Although Figure 61 of Yoakim discloses a flare in its brewing chamber, bodily incorporation is not required, and we are directed to no persuasive argument or evidence that Yoakim could not be configured with a straight chamber, as depicted in Figure 5 of Jarisch. We credit the testimony of Mr. Jobin that a person of ordinary skill in the art would have sought to place the code at the bottom of the flange and would have had a reasonable expectation of success in so doing. Ex. 1003 ¶ 184. For reasons explained above, we assign little or no weight to Dr. Howle’s conflicting testimony because he has little or no experience designing a mechanical beverage system or similar product. See supra 10– 16. Petitioner lays out persuasive reasons why Dr. Howle’s testimony, on this particular point, is “conclusory” and rests on “bodily incorporation” of the references. Reply 24; see id. at 22–24 (pointing out with particularity fundamental flaws in Dr. Howle’s opinions); In re Mouttet, 686 F.3d 1322, 1332 (Fed.

In addition, Patent Owner contends that Yoakim requires that the capsule holder be capable of receiving a set of multiple volume capsules and that there is a “snug fit” to avoid “unbalances.” Sur-reply 8 (citing Ex. 1004 ¶¶ 205, 479, 484, 507, 512). According to Patent Owner, Petitioner does not explain adequately how the use of Jarisch’s “straight chamber” with a capsule holder that does not engage with the side wall of the capsule would allow insertion of multiple volume capsules or permit a “snug fit” in the modified device of Yoakim. Id. at 8–9. Patent Owner’s view that Yoakim discloses the use of certain capsules which might not fit into a device with Jarisch’s non-flared structure is ineffective to undercut the sufficiency of Petitioner’s showing on this point. Petitioner is not seeking a bodily incorporation of Yoakim and Jarisch and, in any event, other embodiments of Yoakim do not require the type of flared capsule identified by Patent Owner. Ex. 1004, Fig. 63. Furthermore, we credit the testimony of Mr. Jobin that one of ordinary skill in the art would have understood how to design the chamber of Yoakim to allow reading of a barcode on the underside of the flange. Ex. 1003 ¶¶ 187–195. With respect to the argument that the use of Jarisch’s design would not allow a snug fit, we are directed to no persuasive evidence that Jarisch’s lack of contact between the capsule side wall and the holder would render the device inoperable or less effective. Resp. 39–40; see Reply 22 (citing Ex. 2019, 36:18–37:6).

    “Petitioner, supported by Dr. Staniford’s testimony, proposes that a person of ordinary skill in the art at the time of the invention “would have had a bachelor’s degree in computer science, computer engineering, or an equivalent, and four years of industry experience,” and “would have had a working knowledge of packet-switched networking, firewalls, security policies, communication protocols and layers, and the use of customized rules to address cyber-attacks.” Pet. 16 (citing Ex. 1003 ¶¶ 23, 25). Patent Owner does not challenge the qualifications proposed by Petitioner for a person of ordinary skill in the art. See generally PO Resp. We find Petitioner’s proposal consistent with the level of ordinary skill in the art reflected by the prior art of record, see Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995); In re Oelrich, 579 F.2d 86, 91 (CCPA 1978), and, therefore, we adopt Petitioner’s unopposed position as to the level of ordinary skill in the art for purposes of this Decision” slip op. at 7

  • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)Plain and ordinary meaningNo construction neededOther

    “We largely agree with Patent Owner that there is no explicit claim- construction dispute. We address Patent Owner’s issues of what ordinarily skilled artisans would have considered in creating and implementing packetfiltering rules in the discussion below. The preservation of the flow of normal legitimate network traffic without disruption is one aspect that those with a working knowledge of packet-switched networking, firewalls, security policies, communication protocols and layers, and the use of customized rules to address cyber-attacks would have considered. Nonetheless, overall, we determine that the plain and ordinary meaning of “configured to prevent an exfiltration operation,” does not require preventing all exfiltrations from occurring, nor allowing all non-exfiltration traffic, and that we need not consider the preservation of the flow of normal legitimate network traffic without disruption in the context of that claim construction. We determine that no claim terms need to be construed expressly for purposes of this Decision.” slip op. at 10

  • Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedDecided for petitioner

    “We agree with Petitioner. The identified aspects of Emerging Threats website would have allowed interested parties to locate the rule sets, download the rule sets and make determinations regarding what rule to use in a packet-handling system, such as Sourcefire. Emerging Threats need not be indexed or broadly searchable under Petitioner’s theory of the ground of unpatentability, namely that Emerging Threats was known, one of ordinary skill in the art would have gone to Emerging Threats, and downloaded the emerging-all.rules file, guided by the documentation wiki. As such, we do not agree with Patent Owner’s argument that “the record evidence of this” slip op. at 16

  • PTAB / AIA Trials › §315(e) estoppelEstoppel appliesDecided for petitioner

    “With respect to Petitioner’s assertions of collateral estoppel, notably in the Petition at pages 47, 49, 51, 52, and 54, with respect to limitations [1a] through [1d], we agree with Petitioner that Patent Owner is estopped from asserting that Sourcefire is not prior art to the challenged claims, and also estopped from asserting that those limitations are not taught or suggested by Sourcefire, to the extent that the limitations “do not materially alter the question” of patentability relative to the elements of the claims of the ’552 patent. See Soverain Software LLC v. Victoria’s Secret Direct Brand Mgmt., LLC, 778 F.3d 1311, 1319 (Fed. Cir. 2015). Independent Claim 1 a. Petitioner’s Assertions As discussed above, we concur with Petitioner that collateral estoppel exists with respect to limitations [1a] through [1d]. Thus, we begin with a discussion of Petitioner’s assertions regarding claim limitation [1e].” slip op. at 21
