    “Relying on the Declaration of Dr. Cooperstock, Petitioner contends that a person of ordinary skill in the art (POSITA) at the time of the invention of the ’682 patent would have had a bachelor’s degree in Computer or Electrical Engineering or equivalent discipline, and approximately two years’ experience in telecommunications or computer networking, whereby additional education could substitute for professional 6 U.S. Patent Appl.

Pet. 13 (citing Ex. 1003 ¶¶ 62–63). We adopt Petitioner’s assessment of the level of a person of ordinary skill in the art because it is consistent with the problems addressed in the ’682 patent and the prior art. See Okajima, 261 F.3d at 1354–55 (holding that absent evidence to the contrary, “the prior art itself [may] reflect[] an appropriate level” of ordinary skill in the art).” slip op. at 10

    “B. Claim Construction We construe each claim “in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent.” 37 C.F.R. § 42.100(b) (2020). Under this standard, claim terms are generally given their plain and ordinary meaning as would have been understood by a POSITA at the time of the invention and in the context of the entire patent disclosure. See Phillips v. AWH Corp., 415 F.3d 1303, 1313 (Fed. Cir. 2005) (en banc). In the Decision on Institution, we determined that no terms of the challenged claims require explicit construction.7 We discern no reason to further discuss construction of any claim terms in this Final Written Decision.” slip op. at 11

    “would have found it obvious to combine the teachings of Burfeind and Crowley (Pet. 15–22), citing Dr. Cooperstock’s supporting testimony (Ex. 1003). In particular, Petitioner posits that a POSITA would have sought references for improving upon “Burfeind’s burdensome and imprecise manual participant selection process,” wherein Crowley is such a reference. Pet. 17–18 (citing Ex. 1005, Abstract, ¶¶ 4, 7–8, 45; Ex. 1003 ¶¶ 81–82). Petitioner contends that Crowley’s system provides numerous advantages, such as “enabling ‘spontaneous socializing’ and ‘convenient communication among friends,’” and “help[s] avoid the problem of friends who were out near each other, but never realized it until later.” Id. at 18–19 (citing Ex. 1005 ¶¶ 6, 35). According to Petitioner, “Crowley thus provides express motivation for implementing its location-based features in Burfeind.” Id. at 19 (citing Ex. 1003 ¶¶ 84–86). Petitioner further contends that a POSITA would have a reasonable expectation of success in implementing the features of Crowley in Burfeind. Pet. 19 (citing Ex. 1003 ¶ 89–92). In particular, a POSITA would have readily been able to adapt Crowley’s location-tracking features “to identify user locations for the purpose of inviting individuals who are located near the event location.” Id. (citing Ex. 1003 ¶¶ 89–90). According to Petitioner, Burfeind and Crowley disclose similar systems for organizing meetings between individuals (id. at 22 (citing Ex. 1004, Abstract; Ex. 1005 ¶ 5)), and because Burfeind “already contemplates techniques for grouping individuals in order to more conveniently select those individuals,” a POSITA “would have thus readily been able to modify Burfeind to determine the event organizer’s contacts that are located proximate to selected event venue.” Id. at 21–22 (citing Ex. 1003 ¶¶ 89–92). Thus, according to Petitioner, the POSITA: would have understood that implementing Crowley’s techniques in Burfeind would merely amount to the use of a known technique (Crowley’s location-based messaging) to improve similar systems in the same way (enabling the system to automatically send messages/invitations to nearby individuals), as well as applying a known technique to a known system ready for improvement to yield predictable results.

    “iv. Claim 1 Conclusion Based on the complete record presented, Petitioner has shown that Gage teaches all limitations of claim 1. Thus, we determine that Petitioner has shown by a preponderance of the evidence that the subject matter of claim 1 would have been obvious over Gage. v. Independent claim 8 Independent claim 8 recites a method of “providing situation related information to a situation authority via a situational network,” wherein the method comprises “receiving, by a participant device, a roll call query soliciting a reply related to a status of a participant based on the participant being determined, by the situation authority, to be geographically proximate to the situation,” “receiving, by the participant device, a selection of a status response from the participant,” and “sending the status response to the central authority, wherein the status response is included in a roll call list.” Ex. 1001, 34:46–57. Petitioner generally refers to its contentions with respect to claim 1. Pet. 34–36. In particular, Petitioner contends that Gage teaches a subscriber device that communicates a status indicator to the disaster response system through a subscriber status reporting system that implements a “situational network” configured for use during disasters. Id. at 34 (citing Ex. 1005 ¶¶ 19, 25). Petitioner additionally contends that Gage’s “disaster response system” is a “situation authority” because the disaster response system detects an occurrence of a disaster affecting a region, receives and aggregates information related to the disaster, and then provides the information to various participants in the network.

Patent Owner does not contest Petitioner’s proposal or offer an alternative. See PO Resp. 18. We apply Petitioner’s definition of a POSITA at the time of the claimed invention because, based on the record, this proposal is consistent with the ’775 patent, the asserted prior art, and is supported by the testimony of Dr. Bhattacharjee.” slip op. at 8

  • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for petitioner

    “We find Patent Owner’s argument that a link is a physical connection (PO Resp. 19; PO Sur-reply 2) unavailing. In particular, claims 1 and 6 do not recite any requirement that a “link” is “physical.” Further, as Petitioner points out, there is no support in the ’775 patent for “defining ‘link’ as only a physical connection,” and Patent Owner does not point to any disclosure in the ’775 patent for such support. Pet. Reply 5. Although we agree with Patent Owner that a link can connect the interfaces of routers wherein routers are “physical devices” (PO Sur-reply 2), claims 1 and 6 do not require that the link physically connects the routers. That is, the claims merely require a pseudo-wire to comprise a link set up between routers to connect the routers. We agree with Petitioner that pseudo-wires comprising the connection links “can connect to any interface, ‘whether it is a physical, logical, or virtual interface.’” Pet. Reply 5 (citing Ex. 1043, 10; Ex. 1010, 3; Ex. 1042 ¶ 7). In fact, during oral argument, Patent Owner acknowledges that “[a] link, . . . , is not limited to a physical connection.” See Tr. 30:6–7.” slip op. at 10

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

    “We find unavailing Patent Owner’s arguments that a pseudo-wire (“a type of emulated connection”) cannot be the same as a link (“a type of physical connection between router interface”). PO Resp. 20. In particular, claim 1 does not recite any requirement that a link be a physical connection, and thus, does not require that a link differs from the emulated connection of a pseudo-wire. As discussed above, during oral argument, Patent Owner acknowledges that a link is not limited to a physical connection. See Tr. 30:6–7. The ’775 patent itself provides no definition for “pseudo-wire” to support Patent’s Owner’s construction, and Patent Owner does not point to any disclosure in the ’775 patent for such support. As Petitioner points out, the ’775 patent instead supports a construction of “pseudo-wire” as comprising multiple links, wherein “[t]he first and second links constitute a first pseudo-wire pw1” and the second “pseudo-wire ps2 consists of the first link L1 and a second link L3.” Pet. Reply 7 (emphasis omitted) (citing Ex. 1001, 6:29–43). We find availing Petitioner’s argument that, even if links were “physical connections” as Patent Owner asserts, “then the pseudo-wire consists of . . . two physical connections,” no different from a link, contrary to Patent Owner’s assertion. Id. (citing Ex. 1042 ¶ 10). Although Patent Owner argues that the POSITA has always considered a pseudo-wire as a point-to-point link set up between input and output routers (PO Resp. 5–6), claims 1 and 6 do not recite that a pseudo-wire comprises a point-to-point link set up, and there is no support in the ’775 patent for specifically defining “pseudo-wire” as and limiting the term to a point-to-point link set up.” slip op. at 12

    “Dr. Bhattacharjee testified in support of Petitioner’s position that “[a] POSITA would have understood that the ordinary meaning of ‘link,’ . . . includes both physical and virtual connections, particularly in the context of pseudo-wires.” Ex. 1042 ¶ 7. We find availing Dr. Bhattacharjee’s testimony, which is supported by evidence. See id. (citing Ex. 1043, 10; Ex. 1010, 3 (disclosing that pseudo-wires encapsulate “data arriving at the PE-bound port (logical or physical)”), 4 (disclosing that the attachment circuit over which the pseudo-wire is established can be a “physical or virtual circuit”)). For the reasons discussed above, we conclude that a “link” is not required to be a physical connection. Instead, we determine that a “link” connects the interfaces of first and second routers, whether they are physical, logical, or virtual interfaces.” slip op. at 11

  • Claim Construction › Functional claiming / §112(f) means-plus-function › Whether §112(f) applies (Williamson, nonce words)§112(f) does not applyDecided for petitioner

    “Here, as Petitioner points out, “the Challenged Claims . . . do not recite ‘means for’ or ‘step for.’” Pet. Reply 1. As the Federal Circuit stated, when a disputed claim limitation does not employ “means for” language, the presumption is that each of the terms conveys sufficiently definite structure or act and, thus, is not subject to § 112(f). See Dyfan, 28 F.4th at 1367. Based on the record before us, this presumption that each of the terms is not subject to § 112(f) is not overcome. Although Patent Owner argues that “to claim a means for performing a specific computer-implemented function and then to disclose only a general purpose computer as the structure designed to perform that function, amounts to pure functional claiming” (PO Sur-reply 5), the question here is whether “means for” analysis under § 112(f) applies at all. That is, as Patent Owner acknowledges, we must determine first whether the claim is even claiming a “means for” performing a function, “and then” determine whether the structure designed to perform that function is a general purpose computer. Id. As set forth in MPEP § 2181, the three-step analysis in determining whether § 112(f) applies begins with determining whether a claim limitation uses 1) the term “means” or “step” or 2) a nonce term used as a substitute for “means” that is a generic placeholder. See MPEP § 2181(I). We agree with Petitioner’s contentions during oral argument that Patent Owner’s arguments appear to be “based on adding a third general purpose computer structure category that triggers MPF treatment not supported by any case law.” Tr. 32:10–12. Accordingly, although Patent Owner argues that “claim 1 invokes § 112[(f)]” (PO Resp. 8, 18), and then provides extensive arguments with supporting testimony from Dr. Jakobsson as to the algorithm defining “local, secured information” (id. at 10–20 (citing Ex. 2016 ¶¶ 18, 38–51, 53–55)) and “algorithm of control logic 250” (id. at 21–25 (citing Ex. 2016 ¶¶ 37, 58)), the presumption that each of the terms is not subject to § 112(f) is not overcome; thus, we decline Patent Owner’s invitation to proceed to determining the corresponding algorithm.” slip op. at 18

In particular, Petitioner contends that a POSITA would have been motivated to integrate a PDK and RDC into a hybrid device by recognizing that Giobbi-157 and Giobbi-139 are “directed to similar operations,” “describe similar structures for performing those operations,” and have techniques that “are compatible with each other,” wherein combining the techniques “would have worked in the same manner already described in the references.” Id. at 21–22. Petitioner then contends that “Dua further corroborates the teachings of the Giobbi references and provides implementation details for integrating an RDC and PDK into the same device,” wherein “a POSITA would have been motivated to combine the teachings of the Giobbi references and Dua” because, at least “these references are all in the same field of endeavor.” Id. at 23–24. Patent Owner does not address separately Petitioner’s explanations and supporting evidence regarding Petitioner’s proffered reasoning to combine the references. See generally PO Resp. We have reviewed Petitioner’s explanations and supporting evidence regarding these limitations, as well as Petitioner’s proffered reasoning to combine the references, and we agree with and adopt them as our own.

In particular, although Patent Owner argues that Giobbi ’157 does not teach or describe unlocking information from a service block in exchange for an access key “as required in the challenged claims” (PO Resp. 30), and thus fails to disclose the “enabling” function as required by the claim, claim 1 merely requires that one or more of the integrated RDC and integrated PDK enables one or more of an application, a function, and a service. In Giobbi ’157, when the PDK enters a proximity zone of the RDC, the RDC requests profile data stored within the PDK for authentication, and if the profile data received from the PDK is valid, the RDC “completes the transaction.” See Ex. 1005 ¶¶ 59–63. We find availing Petitioner’s reliance of Giobbi ’157’s completion of a transaction by the PDK and the RDC to gain access as teaching “enabling access to secure physical or digital assets,” i.e., “enabling one or more of an application, a function, and service” by at least one of a PDK and RDC.

Even if Patent Owner is correct that Li and Wu address the interoperability of IPv4 and IPv6 networks from different perspectives, a person of ordinary skill in the art would have reasonably expected that Wu’s destination port number could be incorporated into the unused padding in Li’s IPv6 destination address.

  • Claim Construction › Functional claiming / §112(f) means-plus-function › Whether §112(f) applies (Williamson, nonce words)§112(f) does not applyDecided for petitioner

    “recite ‘means for’ or ‘step for.’” Pet. Reply 1. As the Federal Circuit stated, when a disputed claim limitation does not employ “means for” language, the presumption is that each of the terms conveys sufficiently definite structure or act and, thus, is not subject to § 112(f). See Dyfan, 28 F.4th at 1367. Based on the record before us, this presumption that each of the terms is not subject to § 112(f) is not overcome. Although Patent Owner argues that “to claim a means for performing a specific computer-implemented function[] and then to disclose only a general purpose computer as the structure designed to perform that function amounts to pure functional claiming” (PO Sur-reply 3), the question here is whether “means for” analysis under 112(f) applies at all. As Petitioner explained during oral arguments, the parties agree that “the law has been consistent and clear” that “the proper framework for an MPF [means-plus-function] construction analysis consists of two steps,” with the first being “determin[ing] whether the limitation is or is not an MPF limitation,” and “[o]nly if the limitation is determined or deemed to be an MPF limitation . . . do you then proceed to step 2 . . . where you analyze the specification of the patent to identify structure corresponding to the MPF limitation.” Tr. 17:22– 18:5. That is, as Petitioner pointed out, “all of the case law identified by [Patent Owner] limits this general purpose computer analysis to the second step of the MPF analysis.” Id. at 19:5–7. Thus, although Patent Owner argues that “[s]ince claim 1 invokes § 112[(f)]” (PO Resp. 9, 22), and then provides extensive arguments with supporting testimony from Dr. Jakobsson as to the “algorithm defining ‘local, secured information’” (id. at 9–19 (citing Ex. 2014 ¶¶ 18, 36–37, 40–54)) and “algorithm of control logic 250” (id. at 19–22 (citing Ex. 2014 ¶¶ 55–57)), the presumption that each of the terms is not subject to § 112(f) is not overcome; thus, we decline Patent Owner’s invitation to proceed to determining the corresponding algorithm.” slip op. at 16

    “would have found it obvious to combine the teachings of Giobbi ’157 and Giobbi ’139 (Pet. 12–22), and furthermore combine the teachings of Dua to the teachings of Giobbi ’157 and Giobbi ’139 (id. at 23–25), citing Dr. Traynor’s testimony for support. In particular, Petitioner contends that a POSITA would have been motivated to integrate a PDK and RDC into a hybrid device by recognizing that Giobbi-157 and Giobbi-139 are “directed to similar operations,” “describe similar structures for performing those operations,” and have techniques that “are compatible with each other,” wherein combining the techniques “would have worked in the same manner already described in the references.” Id. at 20–21. Petitioner then contends that “Dua further corroborates the teachings of the Giobbi references and provides implementation details for integrating an RDC and PDK into the same device,” wherein “a POSITA would have been motivated to combine the teachings of the Giobbi references and Dua” because, at least “these references are all in the same field of endeavor.” Id. at 23.

    “Because the determination of whether the claims invoke § 112(f) comes down to “whether the words of the claim are understood by persons of ordinary skill in the art to have a sufficiently definite meaning as the name for structure” (Williamson, 792 F.3d at 1348), we find Dr. Traynor’s testimony that claim 1 recites sufficiently definite structure persuasive. Ex. 1032. As the Federal Circuit advised in Williamson, declarations and/or testimony of expert witnesses can play a large role in this determination. Williamson, 792 F.3d at 1348. Similarly, in Dyfan, the Federal Circuit found the district court ignored key evidence – unrebutted deposition testimony regarding how a POSITA would have understood claim terms at issue. Dyfan, 28 F.4th at 1367. In particular, the Federal Circuit in Dyfan found to be “key evidence” the expert’s explanation that the terms, themselves, connote structure, wherein, in combination with the recitation of the code or application’s operation would have connoted structure to a POSITA. Id. In this proceeding, we find persuasive Dr. Traynor’s testimony that a POSITA would have understood the terms “local, secured information stored by the integrated, secure memory,” and “wireless communication interface communicating wirelessly with the at least one external device within the proximity zone,” to have “sufficient definite structure, such that a § 112, ¶ 6 interpretation is improper.” Ex. 1032 ¶ 4. In particular, we find persuasive Dr. Traynor’s testimony that the term “memory” alone has definite structure, and, for example, “is defined as the ‘capacity of a computer or integrated computer system for short and medium-term retention of digital data’ and speaks to a broad class of structures used to retain data for various purposes.” Id. at 5 (citing Ex. 1020, 5). According to Dr. Traynor, “not only does memory connote structure, but a POSITA would have recognized that memory can participate in ‘enabl[ing] one or more of an application, a function, and a service’ by simply storing information . . . necessary to access or otherwise invoke that application.” Id. at 6 (first alteration in original). Dr. Traynor’s testimony is consistent with the Specification of the ’960 patent, which describes a microchip that stores information in memory and responds through an antenna when probed. See Ex. 1001, 2:3–29. Similarly, we also find persuasive Dr. Traynor’s testimony that a “wireless communication interface communicating wirelessly with the at least one external device within the proximity zone” also has sufficiently definite structure for performing the function of “enabling one or more of an application, a function and a service.” Ex. 1032, 8. In particular, we find persuasive Dr. Traynor’s testimony that “a POSITA would have understood that an ‘integrated wireless communication interface’ speaks to a class of structures used to connect to wireless networks.” Id. According to Dr. Traynor, “[a] POSITA also would have readily recognized that a ‘wireless communication interface’ is often used to ‘enable one or more of an application, a function, and a service’ by enabling wireless communication of information . . . necessary to access or otherwise invoke that application, function, or service.” Id. at 10. Dr. Traynor cites to various technical dictionaries to persuasively support his testimony. See Ex. 1021 (WILEY ELECTRICAL AND ELECTRONICS ENGINEERING DICTIONARY), 11–12; Ex. 1023 (NEWTON’S TELECOM DICTIONARY), 5; Ex. 1024 (THE AUTHORITATIVE DICTIONARY OF IEEE STANDARDS TERMS), 5–7; Ex. 1025 (MICROSOFT COMPUTER DICTIONARY), 3–4.

    “Here, as in our Institution Decision, we do not discern a significant difference between the parties’ respective proposed definitions beyond the number of years of experience after obtaining a doctoral degree. Compare Pet. 12, with Prelim. Resp. 47, and Resp. 19–20; see also DI 7–8. Under either proposed definition, the ordinarily skilled artisan would have been very highly skilled and educated. For purposes of this Final Decision, we maintain that Patent Owner’s definition appears to be reasonable (and it falls between Petitioner’s two definitions asserted in the reexamination request and in the Petition). Further, Patent Owner’s proposed definition appears to comport with the level of skill in the art reflected in the prior art of record and the ’781 patent itself, for example, Vilkin’s authors are a group of medical doctors and an editor of the journal is a PhD, Joost Louwagie, the named inventor of the ’781 patent, holds a PhD in Biochemistry, and the authors of Itzkowitz are medical doctors and PhDs.
