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

      “We previously determined that, under a broad but reasonable construction, one of skill in the art would have understood the term “virtual private network communication link,” in light of the Specification, to include “a transmission path between two devices that restricts access to data, addresses, or other information on the path, generally using obfuscation methods to hide information on the path, including, but not limited to, one or more of authentication, encryption, or address hopping.” Dec. on Inst. 6–7. 1 Patent Owner disputes this interpretation and argues that the term “virtual private network communication link” must be “a communication path between computers in a virtual private network” (PO Resp. 8), “requir[es] computers within a VPN to communicate directly” (PO Resp. 10), and requires a “network of computers,” which, according to Patent Owner must be “more than a ‘path between two devices.’” PO Resp. 14. We decline to modify our previous construction of this term in the manner suggested by Patent Owner because such a modification is immaterial in this proceeding for reasons set forth below. See Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (claim terms need only be construed to the extent necessary to resolve the case).” slip op. at 3

      “understood that a “secure computer network address” must be “associated with a computer capable of virtual private network communications” because a claim recites “sending an access request message to the secure computer network address using a virtual private network communication link.” PO Resp. 16. We agree with Patent Owner that claim 1, for example, recites “sending an access request message to the secure computer network address using a virtual private network communication link.” However, Patent Owner does not explain sufficiently why an explicitly recited claim limitation must be incorporated into the construction of an associated claim term. Indeed, if one of ordinary skill in the art would have understood that all secure computer network addresses must be associated with a computer capable of VPN communications and that any computer network address that is associated with computers that are incapable of VPN communications would be understood by one of ordinary skill in the art not to be a “secure computer network address” (even if authorization for access is required), then any such recited claim limitation would be superfluous. Patent Owner also argues that “VirnetX’s proposed construction has been agreed to by its litigation adversaries and has been adopted by a district court.” PO Resp. 17. Even if Patent Owner’s proposed construction “has been agreed to by” parties in litigation and the district court, Patent Owner does not assert or demonstrate persuasively that one of ordinary skill in the art would have broadly but reasonably construed the term “secure computer network address” in light of the Specification to require association with a computer capable of virtual private network communications. In any event, Patent Owner does not appear to contend that the cited references fail to disclose a secure computer network address that is associated with a computer capable of VPN communications and, therefore, does not demonstrate sufficiently that the construction of “secure computer network address” will bear on the outcome of the issues in this inter partes review. We decline to modify our construction of this term.” slip op. at 5

      “computer network address” of “the server-side proxy” (and not the “host”). PO Resp. 32 (emphasis omitted). In other words, Patent Owner argues that, in contrast to claim 1, which requires sending a query message requesting an address and receiving a response message containing the address requested in the query message, Kiuchi discloses sending a query message requesting an address of “the host” but receiving a response message containing an address of “the server-side proxy,” rather than “the host.” Based on this presumption that “the host” of Kiuchi differs from the “server-side proxy” of Kiuchi, Patent Owner argues that Kiuchi fails to disclose the claimed invention and also that “the Board has exceeded its statutory authority by instituting in part on rationales that were not before it.” PO Resp. 30. However, Patent Owner does not explain sufficiently a difference between “the host” and the “server-side proxy” of Kiuchi. Kiuchi discloses that a client-side proxy “asks the C-HTTP name server whether it can communicate with the host” and that, in response, the C-HTTP name server examines “the requested server-side proxy” and responds by sending the IP address of the server-side proxy. Ex. 1004, 65 (emphasis added). In other words, Kiuchi discloses that “the host” that is requested is the requested “server-side proxy.”” slip op. at 13

      “of ordinary skill in the art would have combined Kiuchi with the other references.” PO Resp. 3. Petitioner provides reasons with supporting factual underpinnings to support the conclusion that the combination of Kiuchi and Bhatti (and/or Tavs) would have been obvious to one of ordinary skill in the art. Pet. 34–35, 38–39. For example, Petitioner states that one of ordinary skill in the art would implement Kiuchi’s user agent such that the user agent sends an access request for content stored on the origin server, in the same manner that Bhatti describes sending an access request from a user terminal for content stored [on] a content server. Pet. 38. Petitioner also states that “[i]t would have been obvious to one of ordinary skill at the time of the ’180 patent to modify the client-side proxy and server-side proxy described by Kiuchi to support the service-level categorization and differentiation described by Tavs in order to give priority to business-relevant traffic during peak network congestion.” Pet. 34. Patent Owner does not dispute the reasons provided by Petitioner as to why it would have been obvious to one of ordinary skill in the art to have combined teachings of Kiuchi and Bhatti (and/or Tavs) but argues that this obviousness ground “is critically flawed because the Petition relies solely on missing expert testimony for its rationale for combining” the references. PO Resp. 54, 56. However, Patent Owner does not explain why Petitioner is required to provide expert testimony in support of a proposed ground of unpatentability. Nor does Patent Owner explain the supposed flaws in the rationale provided by Petitioner.” slip op. at 21

      “It does not recite “recogniz[ing] that the query message is requesting a secure computer address.” “[T]he claims themselves provide substantial guidance as to the meaning of particular claim terms” and “the context in which a term is used in the asserted claim can be highly instructive.” Phillips, 415 F.3d at 1314. “The construction that stays true to the claim language and most naturally aligns with the patent’s description of the invention will be, in the end, the correct construction.” Phillips, 415 F.3d at 1316 (citations omitted). Based on the context of the claim, the Specification, and the prosecution history, claim 1 does not require “recogniz[ing]” as argued by Patent Owner. As explained in the Background section supra, the Specification describes an “SDNS 3313” that “contains a cross-reference database of secure domain names and corresponding secure network addresses. That is, for each secure domain name, SDNS 3313 stores a computer network address corresponding to the secure domain name.” Ex. 1001, 52:4–8. This disclosure comes closest to aligning with the claim term by explaining how a “secure domain name service” (i.e., an SDNS as set forth in the disclosure) operates. Patent Owner does not point the panel to a disclosure in the Specification that clearly supports the requirement of an SDNS to “recognize that the query message is requesting a secure computer address.”” slip op. at 15

      “that under the claim construction of a “secure domain name” as “a name that corresponds to a secure computer network address,” “Patent Owner . . . concedes Provino discloses this limitation.” Pet. Reply 6–7 (citing Ex. 1003, 13:31–40, 10:45–67; Resp. 26; Ex. 2024 ¶ 28; Ex. 1011 ¶¶ 29–33; Inst. Dec. 8). Petitioner’s argument and showing is persuasive. The claim element does not require any verification that the name is secure.7 Patent Owner also argues that Provino does not teach “receiving a secure domain name” because Provino uses “standard” domain names. PO Resp. 29. Patent Owner points to its Specification that allegedly discusses “an exemplary ‘standard’ domain name ending in ‘.com’ and an exemplary ‘non-standard’ domain name ending in ‘scom.’” PO Resp. 28 (citing Ex. 1001, 51:16–17; Ex. 2024 ¶ 31). These exemplary embodiments do not alter the broadest reasonable claim construction of a “secure domain name.” See supra Section I.E.3., I.E.4. (Claim Construction). As also noted above (id.), Patent Owner made the opposite argument to a district court, and argued that a “non-standard” distinction “is not supported by the specification or the prosecution history.” Ex. 1018, 18.” slip op. at 28

      “Petitioner responds to Patent Owner’s argument as follows: [I]n Provino, before this path between device 12(M) and server 31(s) can exist, nameserver 32 must provide server 31(s)’s secure address. . . . If, in the same response message, a modified nameserver 32 provides QoS parameters, that would necessarily be before the relevant path is established, contrary to Patent Owner’s assertions. Pet. Reply 14 (citing Ex. 1003, 10:56–11:45; Ex. 1011 ¶ 39; Ex. 1089, 58:17–59:16; Ex. 2019, 51:21–55:6). Similarly, according to the Petition, “a person of ordinary skill in the art would have modified the VPN name server 32 of Provino to store, in part, topology dependent QoS parameters, as described by Guillen,” and “[s]uch a modified VPN name server 32 would . . . respond to requests by device 12(m) to resolve the human-readable network addresses of servers 31(S) with both the integer Internet address of the servers 31(S) and the QoS parameters for the servers 31(S).” Pet. 38 (citing Ex. 1011 ¶ 43, Ex. 1005, 82, § 2.3). Petitioner adds that “one of skill would combine Guillen and Provino based on the parallel uses of DNS servers.” Pet. Reply 14 (quoting Ex. 1011 ¶ 42). At the cited paragraph, Dr. Guerin reasons that “Provino relies upon DNS servers to perform address resolution in the context of VPNs in the same manner as Guillen describes their use in the context of ATM communications.” Ex. 1011 ¶ 42 (citing Ex. 1003, 10:45–67). Dr. Guerin also relies on Guillen’s disclosure of using DNS directory servers for address resolution and storing values of QoS parameters to suggest providing indications of feasible QoS levels during address resolution. Ex. 1011 ¶ 41 (citing Ex. 1005, 82, § 2.3). Dr. Guerin also cites Guillen as teaching that QoS parameters relate to guarantees such as bandwidth, and other service requirements, required for multimedia applications, so that “the multimedia application can properly function.” Id. ¶ 40 (citing Ex. 1005, Abstract, 80–82, §§ 2.1, 2.3, 2.4). As outlined above, the parties agree that if the modification would have been obvious, it would apply during address resolution to set up Provino’s tunnel. The parties do not disagree materially, if at all, about what Guillen teaches. On balance, Guillen supports Petitioner’s rationale. See Ex. 1005, 80–82. However, according to Patent Owner, the proposed modification of Provino’s’ nameserver could not work, because “by the time Provino’s device 12(m) accesses nameserver 32, device 12(m) and firewall 30 have already cooperated to establish the tunnel.” PO Resp. 50.

      “Patent Owner’s argument that we should limit “selecting” in claim 1 to “user . . . selecting” (PO Resp. 3) is not persuasive for the reasons that we provided in the Decision to Institute. Inst. Dec. 8–9. In addition, Patent Owner’s proposed claim construction would exclude embodiments in which the image capture device, itself, selects an automatic trigger condition. E.g., Ex. 1001, 10:28–32 (“The camera automatically enters the automatic response mode as soon as power is applied unless otherwise instructed by the operator. Alternately, configuration tools can be provided to select from various sensed conditions.”), 12:23–26 (“Once one or more subjects of interest have been stored, digital image capture device 10 can employ these subjects of interest as image capture triggers whenever it is placed in automatic response mode.”). Patent Owner has not explained sufficiently why “selecting” should be interpreted to exclude such embodiments. See, e.g., Oatey Co. v. IPS Corp., 514 F.3d 1271, 1277 (Fed. Cir. 2008) (holding that, at least where claims can be interpreted reasonably to include a specific embodiment, it is incorrect to construe the claims to exclude that embodiment, absent probative evidence to the contrary). For the above reasons, we determine that the term “selecting” carries its ordinary and customary meanings, and is not limited to acts performed by a user of the image capture device; and we maintain our interpretation.” slip op. at 14

    • Claim Construction › Intrinsic evidence (Phillips canons) › Prosecution history disclaimer / disavowalDisclaimer not foundTerm construed board ownDecided for petitioner

      “[D]isavowal requires that ‘the specification [or prosecution history] make[] clear that the invention does not include a particular feature.’” GE Lighting Solutions, LLC v. AgiLight, Inc., 750 F.3d 1304, 1309 (Fed. Cir. 2014) (quoting SciMed Life Sys. Inc. v. Advanced Cardiovascular Sys., Inc., 242 F.3d 1337, 1341 (Fed. Cir. 2001)). Applying that standard in this case, we are not persuaded that the prosecution history makes clear that claim 1 does not include “entering” of a threshold level by the image capture device itself. The statement on which Patent Owner relies is only part of a sentence; the full sentence reads as follows: In amended Claim 1, a trigger condition and associated threshold [are] selected by a user in a step prior to image capture, the image capture device then monitors a signal corresponding to the trigger condition so that the image capture device can automatically determine when an image should he captured without intervention by a user. Ex. 1015, 6 (emphasis added). The thrust of that sentence, as explained in the paragraph that follows it in the prosecution history, is that, in claim 1, “the timing of image capture[] is determined automatically by the image capture device without the involvement of the user.” Id. (emphasis added). The Beck reference is not distinguished by the applicant on the basis of how the threshold level is selected, but rather on how an image is captured “after a trigger condition and associated threshold ha[ve] been satisfied.” Id. As such, whether “a trigger condition and associated threshold” are selected by a user, or by the device itself, is not central to applicant’s argument distinguishing the Beck reference. Accordingly, the statement that “a trigger condition and associated threshold [are] selected by a user” does not evidence a clear intent to disavow claim scope, contrary to Patent Owner’s contention.

      “In opposition, Patent Owner argues that Mishima fails to disclose entering a threshold level corresponding to the automatic trigger condition, because, as asserted by Dr. Bovik, “the user is not involved in setting the threshold in any way.” PO Resp. 31 (citing Ex. 2006 ¶ 72). As discussed above, however, the user does not need to be involved in setting the threshold level under our interpretation of “entering.” See supra Section II.A.4. That is, the term “entering” is not limited to acts of entering performed by a user, but encompasses acts of entering performed by the image capture device itself. See id. We determine that Petitioner has made a sufficient showing that Mishima discloses “entering a threshold level.” See PO Resp. 32. In particular, Petitioner has shown that, when the user sets Mishima’s device in the automatic mode and selects a reference image for comparison with a captured image or photographic subject, the device sets or selects a threshold level, such as Kn, P, or 40%, and, thus, satisfies the “entering a threshold level” requirement under our claim construction. See Pet. 13–15; Pet. Reply 13–15; Ex. 1002 ¶ 43; Ex. 1016 ¶¶ 13, 48–50; Ex. 1005 ¶ 40 (describing “setting a threshold value Kn” based on reference brightness value K0), ¶ 90 (setting or selecting “X < P” to determine a match, where P is a threshold value and X is the average square of differences between the part that is subject to recognition and the user-selected image pattern); ¶ 114 (describing setting a threshold level as “40%” of “the number of pixels that produce 1”). Moreover, we are not persuaded by Dr. Bovik’s testimony that “the user [in Mishima] is not involved in setting the threshold in any way.” See Ex. 2006 ¶ 72. Dr. Bovik does not address adequately Mishima’s disclosure that the user places the camera in the automatic imaging mode and selects a reference image6 for comparison with a captured image or photographic subject.

Those acts satisfy “selecting an automatic image trigger condition.” See Pet. 14; Ex. 1002 ¶ 42.

      “In opposition, Patent Owner argues that a person of skill in the art would not have combined the teachings of Mishima and Misawa because: (1) the devices of Mishima and Misawa are not similar as Petitioner contends and, in fact, operate in fundamentally different ways, (2) the reasons Petitioner provides for combining Mishima and Misawa are undermined by the teachings of those references, and (3) Misawa would discourage one of ordinary skill from combining it with Mishima to arrive at the inventions of claims 3-6. PO Resp. 34. Patent Owner argues, for example, that Misawa “has nothing to do with automatic image trigger conditions, thresholds, or automatic image capture.” Id. at 35 (citing Ex. 2006 ¶ 91). We are persuaded by Petitioner, however, that Patent Owner’s argument is largely unresponsive to Petitioner’s asserted reason to combine, which “does not rely on Misawa for automatic image capture, but for an example user interface for creating an image database.” See Pet. Reply 15. We also are persuaded that a person of ordinary skill “would have looked to Misawa’s user interface as an example of how to construct/control image feature database 80 used in Mishima’s camera.” Id. at 16 (citing Ex 1005 ¶¶ 80, 94); see Ex. 1016 ¶¶ 53–55. Patent Owner has not persuaded us that using Misawa’s selection/extraction process in Mishima’s camera would have been outside the skill in the art, or yielded an unpredictable result. See KSR, 550 U.S. at 417 (“[I]f a technique has been used to improve one device, and a person of ordinary skill in the art 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.”). Further, we are not persuaded by Patent Owner’s argument that Misawa would have led one in a divergent direction and, thus, teaches away from the recited method. See PO Resp. 44–45 (citing Ex. 2006 ¶¶ 108–111). Patent Owner has not shown that Misawa criticizes, discredits, or otherwise discourages investigation into the invention claimed. See Depuy Spine, Inc. v. Medtronic Sofamor Danek, Inc., 567 F.3d 1314, 1327 (Fed.

In other words, even under Patent Owner’s narrow claim construction that requires an SDNS to perform an additional function (i.e., in addition to resolving a secure domain name (see PO Resp. 16–18)), unlike conventional nameserver 17, secure nameserver 32 directs a message packet to firewall 30, and thereby performs” slip op. at 25

      “artisans would have recognized that Provino’s scheme could have been used to transmit videoconferencing. Pet. Reply 14–15 (citing Ex. 1011 ¶ 42; Ex. 1006, 9, 249, 254; Ex. 1003, 4:35–49, 5:28–35). For example, Petitioner points out that “[a]lthough Provino does not specifically address these [videoconferencing and other claimed applications], it does describe device 12(m) as a system unit having the requisite capabilities, including a video display ‘to display processed data,’ and explains that message packets received ‘contain information such as web pages or the like, . . . to be displayed on the device’s video display unit.’” Id. at 15 (quoting Ex. 1003, 4:35–49, 5:28–35). This record indicates that videoconferencing simply constitutes similar packet data traffic to the traffic that Provino’s system implements. Petitioner also points out that “even Patent Owner’s expert admitted that ‘[Provino is] generally saying that you can send data, and one such type of data is video;’ and could not identify any reason why sending video data on the Provino system would present insoluble problems.” Id. (citing Ex. 1090, 46:12–13, 48:2–7). Dr. Monrose’s deposition testimony supports Petitioner’s characterization of it. For example, Dr. Monrose states that “he didn’t opine on whether or not there’s anything in Provino that would explicitly not allow the sending of video data. This is not in my declaration, as far as I recall.” Ex. 1090, 48:2–7. Dr. Monrose also did not “reflect on . . . whether [data packets that represent video] will be processed differently or not, and how that could impact the operations of Provino.” See id. at 46:17–47:3 (responding to a question during cross-examination). Petitioner further points out that Kosiur provides a “‘background on VPN technologies and products,’ Ex. 1006 at 9, and explain[s] that VPNs can support ‘newer applications, such as interactive multimedia and videoconferencing,’ id. at 254, as well as ‘file transfers, Web browsing, and e-mail,’ id. at 249.” Pet. Reply 14 (quoting Ex. 1006, citing Ex. 1011 ¶ 42). The record suggests that an ordinarily skilled artisan would have recognized that Provino’s system, which sends packets of data over a VPN, including webpages for viewing on a display, could have been modified in a beneficial and predictable fashion, as Kosiur suggests, to send similar packet data to provide videoconferencing on a similar display. “[I]f a technique has been used to improve one device, and a person of ordinary skill in the art 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.” KSR Int’l Co. v.

Kiuchi discloses that a client-side proxy “asks the C-HTTP name server whether it can communicate with the host” and that, in response, the C-HTTP name server examines “the requested server-side proxy.” In response to the request from the client-side proxy, the client-side proxy (i.e., “first network device”) receives “the IP address and public key of the server-side proxy.” Ex. 1004, 65.

Patent Owner does not demonstrate persuasively a difference between Kiuchi and the claimed invention.

However, Kiuchi discloses that in response to the request to communicate with “the host,” the name server examines “the requested server-side proxy” and returns “the IP address . . . of the server-side proxy.” Ex. 1004, 65 (emphasis added). Thus, contrary to Patent Owner’s contention, “the host” of Kiuchi corresponds to the “server-side proxy” (or second network device, as recited in claim 1). Patent Owner also argues that Kiuchi fails to disclose an access request message, as recited in claim 1. In particular, Patent Owner argues that Kiuchi discloses a “user agent” sending a query message for a secure domain service, rather than a “first network device” (i.e., a client-side proxy of Kiuchi) sending a request to a secure domain service. PO Resp. 36 (citing Ex. 2041 ¶ 42 (“Declaration of Fabian Monrose, Ph.D.” or “Monrose Dec.”). We are not persuaded by Patent Owner’s arguments. Dr. Monrose testifies that Kiuchi discloses an “HTTP/1.0 message [that] is sent ‘from the user agent’ and reaches neither the host/origin server nor the server-side proxy.” Ex. 2041 ¶ 42. However, as previously discussed, Kiuchi discloses a step of “sending . . . requests to the server-side proxy” in which “a client-side proxy forwards HTTP/1.0 requests from the user agent” to the server-side proxy. Ex. 1004, 66. Neither Patent Owner nor Patent Owner’s declarant (Dr. Monrose) explains sufficiently how an “HTTP/1.0 request” that is “forwarded” by a client-side proxy to a server-side proxy fails to reach the server-side proxy in Kiuchi or that the forwarded request in Kiuchi is somehow diverted prior to reaching the server-side proxy and does not arrive at its intended destination. Patent Owner also argues that Kiuchi discloses that the client-side proxy “dispatches a new C-HTTP request” but Kiuchi fails to disclose that the client-side proxy sends “an HTTP/1.0 request.” PO Resp. 37. First, we note that claim 1 recites “sending an access request message.” Claim 1 does not recite or otherwise require “sending an HTTP/1.0 request.” For at least this reason, we are not persuaded by Patent Owner’s argument. Also, as previously discussed, Kiuchi discloses “sending . . . requests to the server-side proxy” in which “a client-side proxy forwards HTTP/1.0 requests” to the server-side proxy. Ex. 1004, 66. Patent Owner does not demonstrate persuasively a material difference between the client-side proxy “sending” a request to a server-side proxy and a client-side proxy “forwarding” a request to a server-side proxy. In both cases, a request is transmitted from the client-side proxy to the server-side proxy. Patent Owner argues that Kiuchi discloses an “HTTP/1.0 request” that “is not an access request message [as recited in claim 1] at least because it does not seek any ‘communication, information, or services’ with the serverside proxy.” PO Resp. 38 (citing Ex. 2041 ¶¶ 44, 46). Kiuchi discloses a client-side proxy “[s]ending C-HTTP request to the server-side proxy” in which the “client-side proxy forward HTTP/1.0 request” to the server-side proxy for communication and exchange of services between devices. Ex. 1004, 66. For example, Kiuchi discloses one example in which “patient information” is “transfer[red]” “among hospitals and related institutions.” Ex. 1004, 64. Patent Owner does not indicate sufficiently how Kiuchi’s request for communication between network devices for communication or information (e.g., patient information) exchange, for example, differs from a device seeking “any communication, information, or services.” Hence, to the extent that claim 1 requires seeking “any communication, information, or services,” we disagree with Patent Owner that Kiuchi fails to disclose this feature. PO Resp. 38. Patent Owner argues that Kiuchi fails to disclose sending an “HTTP/1.0 message” using a “virtual private network communication link.” PO Resp. 39. In particular, Patent Owner argues that Kiuchi discloses sending a message from a client-side proxy to a server-side proxy, which, according to Patent Owner, is “a point-to-point connection, not a network as claimed.” PO Resp. 39–40. Patent Owner also argues that Kiuchi fails to disclose sending a request “using a virtual private network communication link” because “the request [of Kiuchi] lacks the ‘network’ aspect of a VPN communication link and further because [Kiuchi merely discloses] a point-to-point message [instead of] a VPN communication link.” PO Resp. 42–43 (citing Ex. 2041 ¶ 52). Hence, Patent Owner argues that Kiuchi fails to disclose a “network.” We disagree with Patent Owner’s argument. For example, Kiuchi discloses one embodiment of the use of a C- HTTP name server (and client-side and server-side proxies) in “networks among hospitals and related institutions.” Ex 1004, 64. At least in view of this explicit disclosure of “networks,” we are not persuaded by Patent Owner that Kiuchi fails to disclose a “network.” Patent Owner argues that Kiuchi discloses sending an HTTP/1.0 request but that “the request must pass through both the client-side and server-side proxies to reach the origin server.” PO Resp. 41 (citing Ex. 2041 ¶ 51). According to Patent Owner, this indicates that “Kiuchi fails to disclose direct communications to any host server and any message from the client-side proxy . . . is not sent using a VPN communication link.” PO Resp. 41–42. Hence, Patent Owner argues that Kiuchi fails to disclose a “direct communication.” Claim 1, for example, recites sending an access request from a first” slip op. at 11

PO Resp. 47–49. Even if the “origin server” of Kiuchi would somehow render the combination of Kiuchi and Bhatti improper, we need not consider Patent Owner’s argument further because, as previously discussed, Petitioner relies on the “server-side proxy” and not the “origin server” of Kiuchi as the recited second network device.

      “As the latter two sentences show, the ’274 patent Specification describes placing field hopping data (i.e., an address hopping technique, see id. at 46:64–47:11), into a payload portion of a data packet. The Specification does not tie “tunneled” packets into a specific requirement that requires a change in formatting––above and apart from any protocol formatting or structural change that may happen to, or does, occur by placing one type of data field (header) into another type of data field (payload). After discussing the insertion of the field hopping data into the payload portion, the Specification then describes that these “modified message packets preferably conform to the UDP protocol,” or “[a]lternatively . . . can conform to the TCP/IP protocol or the ICPM protocol.” Id. at 50:30–35. In other words, if there is a change in a protocol in these disclosed examples––for example, from one protocol format to a UDP protocol format––any change appears to come in preferred embodiments and after the packets have been modified (i.e., tunneled). Accordingly, based on the foregoing discussion, we modify our construction as set forth in the Institution Decision, such that “tunnel packeting” means “placing data or information from one field, such as a header, into another packet field, such as a payload, wherein the two fields normally have different structures or formats, or placing data structured in one format within the format of another protocol.”” slip op. at 22

Petitioner specifically argues that Sierra-1 discloses flexible data transmissions that allows for time slots of data to be mapped from any port card to any forwarding card and Sierra-2 discloses a “‘connection map’ that is used to map data from the link interfaces to the processing engines.” Pet. 29–30 (citing Ex. 1006, 14, Fig. 2; Ex. 1005, 29–30). Sierra-1 further discloses multicast is supported as an output and can sample data from any input. Ex. 1006, 14, Fig. 2. Petitioner argues that it would have been obvious to combine Sierra-1, Sierra-2, and Sierra-3 with the Bell architecture, because Bell specifically mentions the use of Sierra’s cross-connection component. Pet. 30–31 (citing Ex. 1003 ¶ 261); Ex. 1004, 51:56–65.” slip op. at 12

      “Although we agree with Petitioner that Patent Owner’s motion is procedurally defective for the reasons argued by Petitioner (see Opp. 4–6), we also agree with Petitioner that Dr. Lavian’s responses were not “evasive” and highlight this argument for emphasis. For example, Patent Owner’s argument directs us to specific portion of the deposition where Dr. Lavian was asked “did you add that element, 548b?” Supp. Mot. to Exclude 2 (quoting Ex. 2002, 34:18). We agree with Petitioner that Dr. Lavian answered this question to the best of Dr. Lavian’s ability. Opp. 13 (citing Ex. 2002, 34:20–35:2). Furthermore, Patent Owner was able to rephrase the same question and elicit an additional response that Patent Owner did not determine to be “evasive.” See Ex. 2002, 36:6–20. Although Patent Owner directs us to an additional example where Dr. Lavian was allegedly “evasive” and generally concludes that “this type of evasiveness pervaded the entirety of the deposition,” based on our review of Ex. 2002, Patent Owner has not persuaded us that Dr. Lavian did not respond to the questions to the best of his ability. We further agree with Petitioner that Petitioner’s objections were proper. See 37 C.F.R. § 42.53(f)(8) (“Any objection to the content, form, or manner of taking the deposition, including the qualifications of the offier, is waived unless made on the record during the deposition and preserved in a timely filed motion to exclude.”). Based on our review of Ex. 2002, Petitioner’s objections were directed to the content, form, or manner of taking the deposition, and, therefore, were proper under 37 C.F.R. § 42.53(f)(8). We are also not persuaded that the behavior of opposing counsel, alone or “in combination with the occurences at the deposition” (Supp. Mot. to Exclude 4) is a sufficient basis to exclude Exhibit 1003 or Exhibit 1020. Such a remedy is incongruous and disproportional to any alleged harm suffered by Patent Owner during deposition. Accordingly, Patent Owner’s Motion to Exclude Exhibit 1003 and Exhibit 1020 is denied.” slip op. at 15

      “Kitamura is largely silent as to the specific functioning of the D/A conversion circuit 10. Kitamura discloses that D/A conversion circuit 10 and A/D conversion circuit 13 “preferably share a voltage dividing element and a reference voltage supply (for the purpose of making their characteristics uniform),” and level differences to maximize the operating margin (Ex. 1010 ¶ 11), but does not disclose a “selection” between reference voltages or signals. Although Petitioners emphasize the obviousness of certain elements of the challenged claims (Pet. 25– 26), the obviousness of selecting a reference voltage versus outputting a voltage from a D/A conversion is not discussed. Indeed, Dr. Baker’s discussion is clear (Ex. 1003 ¶¶ 74–79) as to how the output voltages could be set, but it remains unclear how Kitamura itself suggests the examples proffered. The normal function of a D/A converter is not to select between reference voltages, but to render the digital input into analog form. We are not persuaded that Kitamura teaches or suggests the selection of one of a plurality of reference voltages in accordance with the input information, per the challenged claims. In addition, the Petitions fail to provide any rationale for why Kitamura’s disclosure of D/A conversion renders the selection of a reference voltage or signal obvious. For these reasons, Patent Owner’s contentions that Kitamura does not teach or suggest “reference voltage selecting means,” or equivalent elements, or “reference voltages,” per the challenged claims, are persuasive.

      “Reference Voltage Selection Claim 1 recites “reference voltage selecting means for selecting one of a plurality of reference voltages,” with claims 9, 12, and 30 reciting “selecting device which selects one of a plurality of reference signals,” and claims 42 and 45 reciting “selecting one of a plurality of predetermined reference signals.” Petitioners acknowledge that the means-plus-function element in claim 1 is “governed by 35 U.S.C. § 112, ¶ 6,” and that the construction of the claim term in claim 1 “is applicable to claim terms” recited in claims 9, 12, 30, 42, and 45, discussed above. Pet. 5, 8. Petitioners assert that “the verify reference voltage select circuit 222 selects and provides such a reference voltage to the comparator,” and is the corresponding structure described in the specification.
