    “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

    “Neither party contends that any formal claim construction is necessary.

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

    “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.

Rather, we find these arguments properly elaborate on the Petition, in response to the proposed construction of “link” in Patent Owner’s Response.

E.g., Ex. 1007 ¶ 83.

    “Weighing the parties’ arguments and evidence, we find that Petitioner demonstrates by a preponderance of the evidence that a person of ordinary skill in the art would have been motivated to combine the teachings of Ji and Sarafa. As explained below, Petitioner persuades us that a person of ordinary skill in the art would have understood that Ji teaches automatic scrolling, and that Sarafa’s automatic scrolling would have beneficially complemented Ji’s. Pet. 21–22; Pet. Reply 14–17; Ex. 1003 ¶¶ 75–77; Ex. 1018 ¶ 47. Additionally, regardless of whether Ji teaches automatic scrolling in paragraph 92, Petitioner persuades us that Ji and Sarafa address similar problems related to tracking and understanding convoluted conversations in messaging systems. See Pet. 16–21; Ex. 1003 ¶¶ 64, 65, 70, 73, 74. As Dr. Cockburn testifies, Ji emphasizes the problem that users cannot quickly find and understand messages in complicated message streams. Ex. 1003 ¶ 64 (citing Ex. 1006 ¶ 2); Pet. 16. Petitioner also persuades us that Sarafa addresses such problems, at least in part, by expressly teaching certain advantages of its scroll-back feature, such that a person of ordinary skill in the art would have considered it advantageous to add Sarafa’s scroll-back feature to Ji’s system. See Pet. 18–19; 21–23; Ex. 1003 ¶¶ 70, 74. For example, addressing the same problems discussed in Ji, Sarafa explains that its scroll back feature would facilitate a user’s ability to understand a complicated conversation because “[m]aking available the context of a quoted message may benefit a user in understanding a quoted message by providing messages that were displayed before and/or after the quoted message so as to play the quoted message in context.” Ex. 1007 ¶ 90; Pet. 19; Ex. 1003 ¶ 70. Similarly, Sarafa explains that its scroll back feature “provid[es] additional context to users . . . , improving the user experience of quoted messages for its users.” Ex. 1007 ¶ 23; Pet. 19; Ex. 1003 ¶ 70. We find that these disclosed benefits would have provided compelling motivation for a person of ordinary skill in the art to add Sarafa’s scroll back feature to Ji’s messaging system. Pet. 19–23; Ex. 1003 ¶¶ 71, 73–77.

    “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. As demonstrated in the analysis below, we need not provide an explicit claim construction for “compress[ing] the estimated CSI.” The ordinary and customary meaning applies to “compress[ing] the estimated CSI.”” slip op. at 30

    “excluded under Federal Rules of Evidence 702 and 703. Rule “702 imposes a special obligation upon a trial judge to ‘ensure that any and all scientific testimony . . . is not only relevant, but reliable,’” which is a “basic gatekeeping obligation.” Kumho Tire Co. v. Carmichael, 526 U.S. 137, 147 (1999) (quoting Daubert v. Merrell Dow Pharm., Inc., 509 U.S. 579 (1993)). The policy considerations for excluding expert testimony, such as those implemented by Daubert’s gatekeeping framework, are less compelling in bench proceedings such as inter partes reviews than in jury trials because, unlike a lay jury, the Board has significant experience in evaluating expert testimony. 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. Furthermore, Patent Owner’s arguments challenging the credibility of Dr. Roy go to the weight that should be given to Dr. Roy’s Declaration testimony, not the admissibility of the Declaration. In our patentability analysis that follows, we account for the evidence that Dr. Roy’s Declaration is substantially the same as Dr. Akl’s Declaration, the supporting evidence cited therein, as well as Dr. Roy’s deposition testimony in determining the appropriate weight to give Dr. Roy’s testimony when weighing the record evidence.” slip op. at 14

One such source for creating a shopping list is “the item selection method, i.e., selecting from a store’s list of available goods.” Id. at 40:50–51. Selecting from the store’s list of available goods provides “assurance of a match between items selected by a customer and items including brand, quantity and price available at the facility” and, thus, “permits for home delivery of items.” Id. at 40:56–60. As Mgrdechian discloses a user, such as a business, providing a list of items for sale (see, e.g., Ex. 1005, 11:28–33), incorporating Swartz’s teaching of home delivery of items selected for purchase does not require the “complete redesign” of Mgrdechian’s system as asserted by Patent Owner.

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

    “heart of the parties’ dispute (Ex. 1001, 2:37–45), we determine that the “for instance” phrase is exemplary and does not limit a “conversational flow” to a specific client or user. The phrase “for instance” is synonymous with “for example,” and necessarily indicates that “the running of an application on a server as requested by a client” exemplifies, but does not limit, the conversational flow to a server and a specific client or user. Our determination that the “for instance” phrase is exemplary and non-limiting is consistent with Patent Owner’s argument in its Preliminary Response that the “some” phrase (“some conversational flows involve more than one connection, and some even involve more than one exchange of packets between a client and server”) is non-limiting. Specifically, Patent Owner argued that the use of the word “some” necessarily means that “some conversational flows involve multiple connections, while, some involve a single connection.” Prelim. Resp. 24. Similarly here, while “conversational flow” certainly may involve the running of an application on a server as requested by a single client or user, “conversational flow” is not limited to a single client or user.” slip op. at 17

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

    “Petitioner has shown by a preponderance of the evidence that the combination of Riddle and Ferdinand renders obvious the recited flow-entry database limitations in view of the proper construction of “conversational flow.” See supra § III.C. Petitioner’s assertions, which we adopt, are supported by the cited evidence and are persuasive. Moreover, we are persuaded that a person of ordinary skill in the art would have been motivated to combine the teachings of Riddle and Ferdinand as proposed by Petitioner and supported by the testimony of Dr. Weissman. See Pet. 25–27 (citing Ex. 1006 ¶¶ 256–257, 259).” slip op. at 44

    “not established by a preponderance of the evidence that claim 3 is unpatentable over the combination of Riddle, Ferdinand, and Wakeman. We agree with Patent Owner that Petitioner provides insufficient evidence to support its contentions. Indeed, the Petition’s discussion with respect to claim 3 does not even cite Wakeman, but instead cites only the testimony of Dr. Weissman and the specification of the ’646 patent. See Pet. 75–76.12 And neither Dr. Weissman’s testimony nor the ’646 patent provides any persuasive support for Petitioner’s assertion that “a [person of ordinary skill in the art] would have understood that Wakeman’s CAM cache is fully associative due to Wakeman not disclosing a cache placement policy indicating there are no constraints on placement within Wakeman’s cache.” We agree with Patent Owner that “Dr. Weissman does not explain why the absence of a discussion of a cache placement policy in Wakeman would lead a [person of ordinary skill in the art] to just assume that Wakeman was teaching using of an associative cache placement policy,” and that his testimony in this regard is entitled to little, if any, weight. PO Resp. 58; 37 CFR § 42.65(a). As Patent Owner contends, Dr. Weissman’s statement that Wakeman could be modified to utilize an associative cache does not 12 To be sure, the discussion of claim 3 in the Petition also includes an internal cross-reference to the “discuss[ion] regarding element 1.3,” i.e., the “cache subsystem” limitation of claim 1, discussed at Pet. 57–59. Although the discussion of that limitation does include citations to Wakeman (see Pet. 58 (citing Ex. 1014, 1:20–28, 1:55–67, 2:31–49, 3:36–45, 4:31–40, 5:22–27, Figs. 2, 3)), however, notably absent from that discussion is any assertion that Wakeman specifically suggests an associative cache. motivated to implement Wakeman’s cache as a fully associative cache. Id. (citing In re Mills, 916 F.2d 680, 682 (Fed. Cir. 1990)). Although we agree with Petitioner that there is no indication that Wakeman disparages the use of an associative cache (Reply 28–29), there still needs to be “some rational underpinning to support the legal conclusion of obviousness” (KSR, 550 U.S. at 418), and we do not find such underpinning on the record before us. Accordingly, we determine that Petitioner has not shown by a preponderance of the evidence that claim 3 is unpatentable over Riddle in view of Ferdinand and further in view of Wakeman.” slip op. at 59
