    “Petitioner contends that a person of ordinary skill in the art in the field of the ’279 patent in January 2001 “would have had a working knowledge of the network communication technologies that are pertinent to the ’279 patent, including network flow allocation in a ring topology.” Pet. 12. More specifically, Petitioner argues, a person of ordinary skill in the art “would have had a master’s degree in computer science, computer engineering, or an equivalent, and two years of professional experience relating to network communications and resource allocations,” where “[a]dditional work experience can substitute for specific educational background, and vice versa.” Id. (citing Ex. 1003 ¶ 20). Patent Owner represents that it “does not dispute Petitioner’s definition” for the purposes of its Response. PO Resp. 5. We find Petitioner’s proposal is consistent with the evidence of record, including the asserted prior art and the ’279 patent, and, therefore, we likewise adopt Petitioner’s proposed definition of the level of ordinary skill in the art for purposes of this Decision.” slip op. at 11

Patent Owner notes, however, that Petitioner had asserted specific constructions in the Cisco litigation for the term “predetermined,” as recited in claims 1, 10, 14–16, and 18, and for the term “quantum.” PO Resp. 4. Specifically, according to Patent Owner, Petitioner proposed that “predetermined” be construed as “determined before the data flow request” and that “quantum” be construed as “an amount of a requested resource by which to increase or decrease.” Id. (citing Ex. 2007). Patent Owner contends asserted prior art combinations disclose or render obvious the challenged claims under these constructions. Id. Because our conclusion that Petitioner has not demonstrated that any of the challenged claims are unpatentable does not turn on the construction of either “predetermined” or “quantum,” there is no need for us to construe those terms.

    “The most common type of MAC bridge is a switch, which has multiple ports connecting it to LANs, other switches, host computing systems, or other network elements. Switches can be roughly classified as access switches or core switches. An access switch has ports that connect to LANs and/or to other network endpoints, such as user computer systems. Core switches interconnect the access switches into a Wide Area Network (WAN), by direct connection between the core switch and access switches and/or by connection to other core switches. Core switches that are directly connected to access switches are referred to herein as edge switches. Ex. 1001, col. 1, ll. 27–38. Both parties refer to this disclosure when arguing whether particular switches in the asserted prior art (Gai) qualify as an “access switch” or “edge switch.” See Pet. 5, 22, 27–28 (“edge switches are ‘[c]ore switches that are directly connected to access switches’”), 71; PO Resp. 31–32 (“The ’986 patent discloses that ‘[a]n access switch has ports that connect to LANs and/or to other network endpoints.’ . . . The ’986 patent also discloses that edge switches are ‘[c]ore switches that are directly connected to access switches.’”); Reply 20, 22. Dr. Houh and Dr. Olivier do so as well. See Ex. 1003 ¶¶ 39, 66–67, 82–83, 166, 171, 193; Ex. 2001 ¶ 80. Based on the full trial record, we agree and conclude that the descriptions of “access switch” and “edge switch” in the ’986 patent reflect what was understood to be the plain and ordinary meanings of these terms at the time of the invention. Accordingly, we interpret “access switch” to mean a switch with ports that connect to LANs and/or to other network endpoints, such as user computer systems, and interpret “edge switch” to mean a core switch that is directly connected to an access switch.” slip op. at 12

    “and conclude that Petitioner has not shown sufficiently that a person of ordinary skill in the art would have been motivated to designate switch 117 as the root switch when implementing the network reconfiguration method of Gai. The only mention of an access switch connected to port 7 of switch 114 is at column 13, lines 59–63 of Gai. While that sentence establishes that such an access switch may exist in the network, it does not state or imply that it would be the root switch. Instead, when discussing the operation of the Figure 1 network, Gai only identifies switches 120 and 121 as the root switch. See Ex. 1005, col. 10, ll. 37–41, col. 11, ll. 60–64, col. 14, ll. 16–20, col. 15, ll. 27–29, 38–51, col. 16, ll. 42–45. To be sure, Gai does disclose that “execution of the spanning tree algorithm causes the switches to elect a single switch, among all the switches within each network, to be the ‘root’ switch,” where “[e]ach switch has a unique numerical identifier (switch ID) and the root is the switch having the lowest switch ID numeric value,” such that an access switch can be the root switch if it has the lowest switch ID. See Ex. 1005, col. 2, ll. 42–47, col. 10, ll. 29–36. As Patent Owner and Dr. Olivier explain in detail, though, Gai expressly cautions against doing so. Gai discloses that [d]epending on the configuration of a given network, the location of the root can significantly affect the distance that messages must travel. For example, many networks include a plurality of switches designated as access switches that provide connectivity to LANs, end stations, etc., and a plurality of backbone switches that, in turn, interconnect the various access switches. If the root is located at an access switch and the principal server utilized by the end stations (i.e., clients) is coupled to a backbone switch, the average distance between end stations and the primary server may be quite high, resulting in inefficient network operation. In addition, the backbone switches may become partitioned as ports between them are blocked. Id. at col. 3, ll. 17–29; see also id. at col. 10, ll. 26–29 (the “location of the root may affect the average distance (i.e., the average number of hops) a message travels and/or cause undesirable partitioning of backbone switches”). Thus, the location of the root is not an unimportant consideration—it affects the distance messages must travel and can cause backbone switches to be partitioned. See id. Gai, therefore, discloses that “[t]o reduce the average distance and avoid partitioning of the backbone switches, it is desirable to locate the root at a backbone switch.”10 Id. at col. 3, ll. 29–31 (emphasis added). Switch 117 in Petitioner’s modified Figure 1 is an access switch, not a backbone switch. See id. at col. 6, ll. 10–12 (“Access switches are preferably coupled to entities (e.g., LANs, end stations, etc.) whereas backbone switches provide the interconnections between access switches.”).” slip op. at 44

    “We agree with Petitioner. For purposes of claim 1, which does not recite “downstream” communication of dummy traffic (unlike claims 11, 12, 23, and 24), the only modification to Figure 1 is the addition of switch 117 and server 112e—otherwise, in Petitioner’s analysis, Gai’s method operates exactly as described when a failure occurs at root port 3 of switch 114. See Pet. 69–73, 81–85; Tr. 47:20–48:2. That modification is expressly supported by Gai, which discloses the following: Rapid reconfiguration entity 234 similarly generates one or more separate multicast messages 400 for each remaining entity directly coupled to access switch 114 (i.e., entities or end stations on LANs 102–104). In each message 400, entity 234 loads SA field 414 with the address of the corresponding entity. Each of these messages are similarly forwarded by access switch 114 through the new forwarding port (i.e., port number four). In addition, entity 234 generates and transmits one or more multicast messages 400 for entities reachable through switch 114 on ports other than its root port. For example, if port number seven at switch 114 were coupled to another access switch, entity 234 would transmit multicast messages 400 carrying the source address of entities directly coupled to this additional access switch as well. Thus, at least one multicast message 400 is generated and transmitted for each entity directly coupled to or downstream of access switch 114 (relative to the root). As set forth above, upon receipt of these multicast messages 400, the other devices within network 100 update their corresponding filtering databases with the new destination ports, as necessary. Ex. 1005, col. 13, l. 50–col. 14, l. 3 (emphasis added). Gai thus expressly contemplates the addition of “another access switch” coupled to port 7 of switch 114. Switch 117 in the modified Figure 1 is such a switch. See PO Resp. 30 (Patent Owner arguing that “a [person of ordinary skill in the art] would understand that switch 117 is an access switch”); Ex. 1018, 84:14–85:9 (Dr. Olivier agreeing that switch 117 is an “access switch”). And because an “access switch” has “ports that connect to LANs and/or to other network endpoints, such as user computer systems,” and the above disclosure mentions “entities directly coupled to th[e] additional access switch,” switch 117 would be directly connected to a device like server 112e as well. See Ex. 1001, col. 1, ll. 31–33; Ex. 1005, col. 13, ll. 59–63; supra Section II.B. We credit Dr. Houh’s testimony that Gai in its written description expressly discloses the particular “variation of the topology” of Figure 1 that Petitioner asserts. See Ex. 1003 ¶ 165. Third, Patent Owner argues that Petitioner has not established that a person of ordinary skill in the art “would have had a reasonable expectation of success in modifying Gai to meet the claims.” PO Resp. 14–16 (citing Ex. 2001 ¶¶ 47–49). Patent Owner’s arguments are primarily directed to Petitioner’s asserted modification for its “1A” theory. See id. To the extent Patent Owner’s arguments apply to claim 1 and “1B,” we disagree, as Gai expressly describes the asserted modification to Figure 1 (i.e., adding an access switch connected to port 7 of switch 114). Thus, we are persuaded that a person of ordinary skill in the art would have had a reasonable expectation of success in achieving the method of claim 1 based on Gai’s full disclosure.” slip op. at 33

Second, we find his testimony entitled to very little weight because he applies an incorrect understanding of the caselaw, which mirrors Petitioner’s incorrect and arguably misleading quotations of the Federal Circuit’s decision in Quest. In particular, in paragraph 5, Mr. Hutton states the following as his understanding of the law as it applies to prosecution disclaimer: “I also understand that in order to disclaim embodiments within the specification, the statements should have some indication that the applicant intended to surrender embodiments from the specification.” Ex. 1038 ¶ 5 (emphasis added). This then leads Mr. Hutton to state: “[t]hus, in my opinion, a [person of ordinary skill in the art] would not view applicant’s statements as a disclaimer, because the applicant never stated that they intended to surrender multiple embodiments described in the specification.” Id. ¶ 13 (emphasis added). As we explained above in responding to a similar argument by Petitioner, the caselaw does not require an applicant to expressly state whether a disclaimer excludes particular embodiments of the subject specification when disclaiming claim scope during prosecution. See Quest, 924 F.3d at 1229. And, as noted above, counsel for Petitioner agreed that such a statement explicitly disclaiming particular embodiments is not required. Tr. 12:18–13:17. Third, although we have considered Mr. Hutton’s testimony, we find it “less significant than the intrinsic record in determining the legally operative meaning of” “pre-printed lottery ticket.” Phillips, 415 F.3d at 1317. In particular, we are cognizant of the Federal Circuit’s guidance that we “should discount any expert testimony that is clearly at odds with the claim construction mandated by . . . the prosecution history.” Id. at 1318 (internal quotation omitted). In this instance, for the reasons explained above, we find that Mr. Hutton’s testimony is clearly at odds with the applicant’s arguments during prosecution and that his testimony is based on a misunderstanding of what is required by the governing caselaw for prosecution history disclaimer.” slip op. at 43

Although Patent Owner proposes an alternative level of ordinary skill in the art, Patent Owner does not explain how it impacts Petitioner’s contentions or Patent Owner’s arguments in opposition. Indeed, at the hearing, Patent Owner’s counsel stated “I can’t point to a material difference that would change the outcome of this.” Tr. 49:10–15. Therefore, it appears that neither party contends that the differences in their proposals affects the outcome of this proceeding.

    “We determine Patent Owner’s reading of the claim limitation is the better one. The limitation begins with the verb “locating,” and it therefore makes sense that the clause would recite what is located (i.e., encryption information) and where it is located (i.e., within the requested portions of the selected stream of protected video). In other words, it is reasonable that the second and third clauses of the limitation both modify the first clause (for example, as could perhaps be expressed through the use of commas as “locating encryption information, that identifies encrypted portions of frames of video, within the requested portions of the selected stream of protected video”).10 On the other hand, Petitioner’s reading of the limitation, 10 In general, we recognize that the use of commas to set off phrases in claim drafting is not consistent. We included commas above to illustrate Patent Owner’s understanding of the claim limitation. allowing only the second clause to modify the first, while not unreasonable, makes less sense. That is, the encrypted information identifies the encrypted portions of frames, which in turn are within the requested portions of the selected stream of protected video. Reading the claim in its entirety, the encrypted portions of frames would be understood to be located within the requested portions of the stream; it does not seem necessary for the claim to expressly recite that aspect. For example, the very next limitation— limitation [m] of claim 1—refers to “each encrypted portion of the frames of video” but does not expressly recite “within the requested portions of the selected stream.” Ex. 1001, 27:58–60. Thus, when limitation [l] recites “within the requested portions of the selected stream,” it seems more likely that the clause refers to where that encrypted information is located rather than simply to indicate the obvious location of the encrypted portion of the frames of video. We therefore view Patent Owner’s reading of the claim language as the better one.” slip op. at 13

    “We do not agree with Patent Owner that Petitioner’s showing uses the same sound data to teach the “first sound data” of limitation 1.a and the “second sound data” of limitation 1.c. Patent Owner is correct that Rosenberg’s claim 5 describes the determination of a volume threshold based on the volume of the ambient audio signal in which characteristic form(s) (e.g., the name of the user of the media player) are present. Ex. 1006, 13:66–21, 14:28–30. However, the Petition describes using Fu’s “predetermined threshold” in combination with Hart-787’s device, which attenuates audio output of a device upon detecting a user’s utterance intended to gain the attention of the device, in order to “include adjusting the audio output volume of a wirelessly-linked audio-producing device when the voice-controlled device determines that the ambient noise level at the time a Ex. 1004, 2:22–37, 5:61–6:10, 9:18–25; Ex. 1005 ¶¶ 24, 32, 54; Ex. 1003 ¶¶ 88–89). Petitioner further proposes including a threshold that is advantageously based on the environment in which the device is operating as described in Fu, for example to respond to differing levels of noise at different times of day. Id. at 26, 29–30, 40 (citing Ex. 1006, 10:42–67, 14:28–30; Ex. 1003 ¶¶ 48–53, 55, 58, 87, 91, 107–109). We agree with Petitioner that Patent Owner’s arguments address the references individually instead of addressing the combination of the teachings proposed in the Petition. See Pet. Reply 8, 13–14; see also Dec. on Inst. 21–22, 23–24, 25–26. The Petition relies upon a combination of elements of Hart-787 with the predetermined threshold as taught in Fu and with establishing such a threshold based on the operating environment of a device as in Rosenberg. Pet. 26–31, 34–41. Patent Owner is correct that Rosenberg’s threshold is set at the time of the utterance in Rosenberg’s claim 5 and cites Petitioner’s declarant as “conceding” issues regarding how “Rosenberg’s volume threshold is determined.” PO Resp. 20–21. But this argument and the ostensible concession do not squarely address the proposed combination, which combines Fu’s teaching of an adjustment unit that “compares the volume of the ambient noise received . . . to a predetermined threshold” with Rosenberg’s teaching that such “a threshold may be ‘determined based on the volume of [an] ambient audio signal.’” Pet. 39, 40 (emphasis omitted) (quoting Ex. 1006, 14:28–30). While Patent Owner argues that “Petitioner has not proposed using a predetermined/pre-set threshold or a previously established threshold based on environmental noise in the combination of Hart-787 with F[u] and Rosenberg” (PO Resp. 46), we find, on the contrary, that the Petition describes a combination based predetermined threshold” and on a threshold “determined according to an environmental noise level.” Pet. 29–30. Thus, we find Petitioner’s unpatentability grounds do not suffer from the issues Patent Owner argues are a consequence of the purported use of the same sound data for the “first sound data” of claim limitation 1.a and for the “second sound data” of claim limitation 1.c. We do not agree with Patent Owner’s arguments regarding Fu’s teachings with respect to limitation 1.e’s “transition from a first state having a first volume level to a second state having a second volume level that is less than the first volume level” because these arguments similarly do not address the proposed combination. See PO Resp. 26–30. The Petition cites Hart-787 for attenuating the volume of an audio-producing device when a wake word is issued. Pet. 32–34, 43–44. The Petition cites Fu for adjusting volume of an audio-producing device if the level of ambient noise exceeds a predetermined threshold. Id. at 36–39, 44–45. Thus, even if Fu teaches only increasing the volume of an audio-producing device if the predetermined threshold is exceeded, the Petition relies on the combination of teachings of Hart-787 and Fu, and Patent Owner’s argument that neither reference teaches “decreasing a controllable appliance’s volume output when a previously established volume threshold is exceeded” (PO Resp. 30) does not address the combination proposed. Patent Owner’s argument that “Petitioner has not proposed modifying Fu to decrease a controllable appliance’s volume output when a volume threshold is exceeded” (PO Resp. 30) similarly does not address the combination proposed in the Petition.

    “We agree with Petitioner’s arguments. Petitioner is correct that the ’204 Patent does not redefine compression to exclude quantization, or otherwise disavow the scope of “compression.” We also agree that compression is a broad and basic term that encompasses any form of compression. We agree, however, with Patent Owner that compression and quantization should not be interpreted as having the exact same meaning. Patent Owner’s arguments, however, focusing on the purposes of quantization and compression are misplaced. In cases where quantization results in a reduced data size, quantization can be encompassed by the term compression. We find that, consistent with the ’204 Patent Specification, the scope of the term “compress[ing]” may include quantization, so long as the quantization results in using fewer bits than the original digital representation, i.e., a reduction in data size. For the foregoing reasons, we decline to adopt Patent Owner’s proposal that “‘compress[ing] the estimated CSI,’ should be construed as plain and ordinary meaning, which excludes ‘quantizing the estimated CSI’ without further separately applied compression.” See PO Resp. 20; PO Sur-reply 9.

Accordingly, the danger of prejudice in this proceeding would be considerably lower than in a lay jury trial and the wholesale exclusion of a witness’s declaration is rarely called for in a proceeding before the Board.

    “metadata into its signature generating algorithm to create a more robust signature. Ex. 1005 ¶ 46. An ordinarily skilled artisan would have been motivated to use such an augmented signature generating algorithm in Field’s environment. Ex. 1002 ¶¶ 138–139; Ex. 1004 ¶ 40. Thus, an ordinarily skilled artisan would have modified Field’s cryptographic signature generating algorithm so it would compute a file’s signature using a file’s metadata. Ex. 1002 ¶¶ 138–139; Ex. 1004 ¶ 40. Accordingly, Field and Anderson disclose that “the cryptographic signature is also computed with the metadata.” Ex. 1002 ¶¶ 138–139; Ex. 1004 ¶ 40.” slip op. at 76
