    “A person of ordinary skill in the art (“POSA”) at the time of the purported invention would have had either: (1) a Bachelor of Science degree in computer science, electrical or computer engineering, or a related field, and at least 2 years of work or research experience in digital communications systems, such as wireless communications systems and networks, or equivalent, or a Master’s degree in electrical engineering, computer engineering, computer science or similar field. Additional education could compensate for less practical experience and vice versa. Ex. 1002, ¶¶1-46. Pet. 10. Patent Owner does not address the level of ordinary skill in the art. Cf. Ex. 2007 ¶19 (Patent Owner’s declarant, after acknowledging Petitioner’s definition, stating: “Patent Owner has not offered a different understanding of a POSITA, and the PTAB accepted Petitioner’s submission. I accept and use Petitioner’s and the PTAB’s definition of a POSITA.”). Petitioner’s definition is consistent with the level of ordinary skill reflected in the prior art references of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (recognizing that the prior art itself may reflect an appropriate level of skill in the art). For purposes of this decision, we apply Petitioner’s definition of the person of ordinary skill in the art.” slip op. at 11

    “During oral argument, both parties confirmed their respective positions that the claim term “route” needs no construction. See, e.g., Tr. 11:7–9 (Petitioner’s counsel: “Frankly, it doesn’t make any difference to the analysis of the prior art. And so, we don’t believe that the PTAB needs to construe the term route, and so we have not proposed a construction.”); id. at 58:25–59:2 (Patent Owner’s counsel: “You know, I don’t think that you have to define routing in order to decide the case. I think you can do it, you know, just apply whatever plain and ordinary meaning is.”); cf. Tr. 40:14–18 (Patent Owner’s counsel at oral argument: “For the routing itself, you know, there is a District Court construction and that’s a construction that the other—the Petitioner did not ask for determination whether that’s appropriate or not appropriate here. We did not address that as well, so the parties aren’t arguing that that construction should be applied here.”). For the reasons discussed below, we determine that Petitioner has not proven by a preponderance of the evidence that the prior art discloses or teaches, under Petitioner’s articulated theories, that a second transceiver routes information based on monitored characteristics. This is dispositive of the inter partes review. Accordingly, we determine that no claim terms require express construction for purposes of deciding the dispositive issues.” slip op. at 13

    “Ex. 1004, 5:25–36 (emphasis added). Thus, Palmer discloses that the determination to roam to another cell may be done by the mobile worker’s wireless communication device 20 having a specifically-programmed processor or may be done centrally, with examples being the “network” or central host processor. We disagree that this constitutes a disclosure of the access point 40 performing the roaming determinations. Rather, we find to be persuasive and credible Dr. Chrissan’s testimony that “a POSITA recognizes that an access point does not qualify as ‘centrally, for example, by the network or a central host processor,’” and, “[i]nstead, this phrase refers to one of the centrally located devices such as network 14 or central host processor 12 (in Fig. 1), or a device in administration building 33 (in Fig. 2).” Ex. 2007 ¶ 71 (citing Ex. 1004, Figs. 1, 2).

    “We determine that Petitioner has not established by a preponderance of the evidence its foundational assertion that Palmer discloses that “access point 40 determines whether roaming by a portable terminal 20 should take place and routes data packets accordingly.” Pet. 26–27; see Technology Licensing Corp. v. Videotek, Inc., 545 F.3d 1316, 1327 (Fed. Cir. 2008) (“Failure to prove the matter as required by the applicable standard means that the party with the burden of persuasion loses on that point—thus, if the fact trier of the issue is left uncertain, the party with the burden loses.”). As such, Petitioner has not met its burden to show that Palmer discloses, as recited in independent claim 1, a second transceiver that, “based on the first signal characteristics and the second characteristics, routes information to the first mobile station and the second mobile station, respectively,” or, as recited in independent claim 6, “based on the first signal characteristics and the second characteristics, routing, using the second transceiver, information to the first mobile station and the second mobile station, respectively.” Ex. 1001, 10:38–44, 11:19–22. The Petition does not contain a contention that this “route” aspect of the claims would have been obvious. Compare Pet. 25–26 (offering an alternative argument for the monitoring aspect; contending that, “to the extent the Board disagrees that Palmer’s access point 40 performs the monitoring, it would have nonetheless been obvious to a POSA to select the access point 40 to perform the monitoring since it directly communicates with the portable terminals 20.”), with id. at 26–27 (making the anticipationtype contention that “[t]he access point 40 routes information” without an alternative obviousness contention); see also Pet. Reply 12–13 (arguing, under the monitoring-and-routing heading, that monitoring by the access point would have been obvious, but not arguing the same for routing). Petitioner has not shown by a preponderance of the evidence that independent claims 1 and 6 and dependent claims 2–4 are anticipated by or would have been obvious over Palmer.” slip op. at 28

L. No. 112-29, 125 Stat. 284 (2011) (“AIA”), amended 35 U.S.C. § 103. Because the challenged claims of the ’414 patent have an effective filing date before the effective date of the applicable AIA amendments, we refer to the pre-AIA version of 35 U.S.C. § 103 throughout this Decision. 2 Mauer et al., U.S. Patent No. 7,395,085 B1, issued July 1, 2008 (Ex. 1005, “Mauer”). 3 Waylett et al., U.S. Patent No. 8,184,603 B2, issued May 22, 2012 (Ex. 1006, “Waylett”). computer science, electrical or computer engineering, physics, or a similar discipline . . .

The institution decision adopted Petitioner’s definition of a person having ordinary skill in the art. Dec. on Inst. 11–12. Patent Owner applied this definition for its response. Resp. 19. Petitioner’s undisputed definition of a person of ordinary skill in the art is reasonable and consistent with the prior art and ’414 patent specification. Based on the record before us, we adopt Petitioner’s undisputed proposal. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

    “a) Combination of Mauer and Waylett In support of both Ground 1 and Ground 2, Petitioner argues that a person of ordinary skill in the art would have been motivated to combine Mauer’s and Waylett’s disclosures, “using Waylett’s Network-in-a-box 224 in each of Mauer’s WWAN 14 and WLAN 12, resulting in at least two DMA systems.” Pet. 11–13. Asserting that “Mauer teaches providing sufficient network coverage by use of different kinds of networks, network interfaces, and protocols,” Petitioner contends that a person of ordinary skill in the art would have recognized that “Waylett discloses an inexpensive way to implement the same networks used in Mauer’s WWAN 14 and WLAN 12.” Id. Citing similarities in Mauer’s and Waylett’s systems, Petitioner argues that “a POSITA would have been able to modify Mauer’s WWAN 14 and WLAN 12 networks so that each network uses Waylett’s NIB 224.” Id. at 14. According to Petitioner, the combination would have included a number of beneficial features from Mauer. Id. at 14–15. Petitioner further advances three reasons that a person of ordinary skill would have had to combine the references’ teaching. Id. at 15–16. First, asserting that Waylett discloses cost benefits and Mauer discloses “an improved method and system for notifying mobile stations,” Petitioner contends the “references each provide reasoning” to combine their disclosures. Id. at 15. Second, Petitioner argues that a person of ordinary skill in the art would have been motivated to “improve Mauer’s distributed wireless network system by consolidating it into a single box, making it compact in design allowing for faster deployment.” Id. at 16. “Third, Waylett’s NIB would help mitigate the shared concern of Mauer—that is, reaching a mobile station as it roams or moves outside of the service or coverage area.” Id.” slip op. at 24

    “Petitioner does not establish that Mauer sends calls to voicemail based on the two determinations claim 1 recites. Resp. 55–56. In particular, as we explain above, claim 1 requires making use of the DPR after first determining the second mobile subscriber is not located within a first wireless coverage area based on HLR and VLR information and also determining that the second mobile subscriber is not located within a second wireless coverage area based on certain CLR information. The Petition, at best, attempts to establish that Mauer directs to voicemail when a “communication session cannot be established over the first or second wireless network.” Pet. 37. But a general determination that a “communication session cannot be established” does not teach or suggest claim 1’s specific requirements that first, the DPR is utilized in the specific circumstance that the second mobile subscriber is not located within the first wireless coverage area (with this determination being made based on HLR and VLR information), and second, that the DPR is also not located within the second wireless coverage area (with this determination being made based on CLR information). See PO Sur-Reply 8–9; Ex. 2001 ¶¶ 111–113.

    “2. Conclusion as to Obviousness For the reasons above, we determine that evidence independent of inventor testimony corroborates (1) a conception date no later than October 22, 2000 and (2) reasonably continuous diligence in reducing the claimed invention to practice until January 19, 2001. Having considered the evidence as a whole under a rule-of-reason analysis, we determine that Unified has not shown that the conception date for the claimed invention was on or after October 24, 2000, or that the inventors did not exercise reasonably continuous diligence during the critical period between October 24, 2000 and January 19, 2001. Unified relies on a priority date of October 24, 2000 for Olgaard and a priority date of December 22, 2000 for Acharya. See Pet. 1–2 & n.2; see also Ex. 1005, code (63); Ex. 1007, codes (22), (43). However, the corroborated conception date for claims 27 and 28 antedates the above priority dates for both Olgaard and Acharya. See supra Section III.C.1. Thus, Unified has not shown that either Olgaard or Acharya is prior art under 35 U.S.C. § 102(e) (2006). Unified provides no theory of obviousness that does not depend on either Olgaard or Acharya being prior art. See Pet. 2, 8–80.” slip op. at 20

First, we find credible Mr. Chang’s testimony that Exhibit 2013 and other related drafts, including their filenames and metadata, have not been altered. Ex. 2031 ¶ 1. We regard the metadata as the most reliable indicator of the latest date each draft was completed. Although the filename dates may differ from the metadata dates, these minor differences do not call into question the reliability of the metadata as the last date on which the drafts were modified. Most significantly, the “last modified” date for Exhibit 2013 is October 22, 2000. That the inventors produced at least three other drafts and then filed a provisional application just ten days later on November 1, 2000 further supports a conception date before October 24, 2000.

See, e.g., Ex. 1101, Figs. 2a, 2b, 3a, 3b, 4a, 4b, 3:22–7:44. On the other hand, we also determine that Patent Owner’s proposal is too narrow. A person could, for example, have ordinary skill in the art of the ’060 patent by virtue of non-professional experience (for example, academic experience).

Moreover, even if “Kuo’s network provides multipoint connectivity similar to Balakrishnan” (Ex. 1003 ¶ 225 (emphasis added)), this is merely a high-level feature or goal of many such networks and does not itself show why the skilled artisan would have had a reasonable expectation of success in modifying Kuo’s particular network to periodically synchronize forwarding tables given the particular design of Kuo’s system, and given the complex nature of virtual private local area networking technology (and computer networking technology generally).

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “Patent Owner “takes no position with respect to Petitioner’s proposed level of skill” and does not offer any alternative characterization. PO Resp. 16. We adopt Petitioner’s characterization of the level of ordinary skill, which we determine is consistent with the ’150 patent’s written description and the asserted prior art.” slip op. at 6

    “B. Claim Construction Neither party proposes that we construe any claim term (Pet. 8; PO Resp. 6), and upon reviewing the record, we determine that it is not necessary to expressly construe any claim term. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017); Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (“[O]nly those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy.”).” slip op. at 6

  • Expert testimonyPetitioner expert discountedDecided for patent owner

    “This cross-examination testimony by Dr. Yang, however, is conclusory and thus not persuasive. Dr. Yang does not identify the common features and similarities in the packet header formats between VPLS and Togazaki, nor did she explain why, in light of those features and similarities in the packet headers, it would be easy to bring VPLS into Togazaki. Ex. 2012, 90:25–91.6, 103:11–18. She merely concluded that doing so would be easy. Id. Further, Dr. Yang has not identified the modifications that would be required to provision a VPLS on Togazaki or why an ordinarily skilled artisan would have found those modifications to be minor. Id. Admittedly, it can be difficult for an expert to support cross-examination testimony during cross-examination, but Petitioner had other means to support this testimony. Petitioner could have questioned Dr. Yang on redirect to support this testimony. Further, Petitioner could have submitted a reply declaration from Dr. Yang, particularly where Petitioner knew that it would be relying on this cross-examination testimony in its Reply. Moreover, Dr. Yang could have analyzed the issue of reasonable expectation of success in her original declaration and provided this testimony and its support there. But Petitioner and Dr. Yang did not support the cited cross examination testimony, and unsupported expert testimony is not persuasive. In sum, we determine that Dr. Yang’s declaration and cross- examination testimony do not support a finding of a reasonable expectation of success.” slip op. at 14

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot shown unpatentableMotivation not foundNot shown unpatentable

    “We determine that Petitioner has not proven that an ordinarily skilled artisan would have had a reasonable expectation of success in provisioning a VPLS in Togazaki. Neither the Petition nor the declaration from Dr. Yang that accompanied the Petition analyzed whether an ordinarily skilled artisan would have had a reasonable expectation of success in provisioning a VPLS in Togazaki. Pet. 8–51; Ex. 1003 ¶¶ 66–107, 157–170. Dr. Yang did not submit a second declaration in this proceeding. Pet. Reply (Exhibit List). Nevertheless, Petitioner argues that it proved the requisite reasonable expectation of success with the evidence that it cited in the Petition for other issues (e.g., motivation to combine) including Dr. Yang’s declaration testimony on those issues, Dr. Yang’s cross-examination testimony, Dr. Akl’s cross-examination testimony, and additional evidence that Petitioner cited in its Reply. Id. at 29–33. As set forth below, although we agree with Petitioner that the cited prior art teaches provisioning VPLSs in certain prior art systems, that prior art teaching by itself does not establish a reasonable expectation of success in provisioning a VPLS in Togazaki’s system. Further, the expert testimony and other evidence cited by Petitioner fail to prove, by a preponderance of the evidence, that an ordinarily skilled artisan would have had a reasonable expectation of success in provisioning a VPLS in Togazaki’s system.” slip op. at 10
