    • BurdenFwd all claims patentableNot shown unpatentable

      “4. Conclusion for the Prior Art Analysis In sum, we find that Zhou does not disclose the low-light high-pass parameter or the stickiness parameter. Petitioner’s grounds for both independent claims 1 and 16 rely on Zhou for teaching a low-light high-pass parameter or a stickiness parameter. Pet. 23–28, 64. Because we find Zhou does not teach these limitations, all of Petitioner’s grounds fall for this reason. III. CONCLUSION For the reasons given above, we determine that Petitioner has not established by a preponderance of the evidence that any claim of the ’840 patent would have been obvious in view of the prior art cited.” slip op. at 18

      “A person of ordinary skill in the art (POSITA) in the field of the ’840 patent would have a bachelor’s degree in engineering or computer science, or equivalent field, and two years of experience working on image or video processing, or digital cameras. Alternatively, a POSITA would have four years of experience working on image or video processing, or digital cameras. An advanced graduate degree in the disciplines cited above may make up for the work experience indicated above. Pet. 6 (citing Ex. 1002 ¶ 32). Patent Owner applies the same standard. PO Resp. 26–27.

      “We review this testimony based on the strength of the underlying factual basis. 37 C.F.R. § 42.65(a); Ashland Oil, Inc. v. Delta Resins & Refractories, Inc., 776 F.2d 281, 294 (Fed. Cir. 1985) (“Lack of factual support for expert opinion going to factual determinations, however, may render the testimony of little probative value . . ..”). Here, the underlying factual basis is not very strong for either witness. That said, we find that Dr. Foroosh’s testimony is more logically sound and consistent with the ’840 patent disclosure. Based on our reading of the specification, we find a clear indication that “stickiness” has to do with the past. In order to control “the extent by which preceding portion(s) . . . impacts determination of the smoothed trajectory” (emphasis added), one must control the degree by which the past frames impact determination. And to control the degree of the past’s influence, one must, as a consequence, favor the past over the future. That is, the frame of reference of the stickiness parameter is the past. The specification could have used a time-agnostic term, like a “nearness” or “adjacency” parameter, but it did not. Thus, the fact that “stickiness” is used in conjunction with “preceding” indicates that it deals with a preference for preceding frames. On this basis, we find Dr. Katsaggelos’s testimony less persuasive than Dr. Foroosh’s.” slip op. at 10

      “That said, we do not construe a stickiness parameter as prohibiting consideration of future frames. Instead, we determine that the stickiness parameter’s value determines the impact of the preceding portions, versus the following portions. The ’840 patent recognizes this, when it says that a stickiness parameter value of “1,” representing a “lazy” stabilizer that maximally favors the past, would not override a violation of the margin constraint based on the look-ahead (i.e., would not allow the viewing window to fall out of bounds in the event of large future motion). See Ex. 1001, 22:26–30; see also id. at 12:61–13:29 (acknowledging that favoring the past may lead to a conflict with the viewing window determination), 15:39–60 (adjusting the viewing window to ensure it does not violate a margin constraint). Thus, while a past-favoring parameter by necessity favors the past over the future, it does not prohibit consideration of the future. In view of the above, we construe the claimed “stickiness parameter” as a parameter that controls the extent by which preceding portions of the trajectory impacts determination of the smoothed trajectory, with an understanding that in order to favor preceding portions, to some extent, the parameter must relatively disfavor following portions.” slip op. at 10

      “II. ANALYSIS A. LEVEL OF ORDINARY SKILL Petitioner defines the person of ordinary skill in the art as follows: As of February 2006, a person of ordinary skill in the art (“POSITA”) would have been a person with a degree in 1 The Leahy-Smith America Invents Act, Pub. 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 . . . [and] would also have at least two years of relevant experience including, for example, work related to telecommunications networks. Pet. 3 (citing Ex. 1003 ¶ 54). 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. Cir. 2001) (the prior art may reflect an appropriate level of skill in the art).” slip op. at 12

      “Petitioner does not submit constructions for any claim terms. According to Petitioner, “[t]he Board construes claims under the same standard used in civil actions in federal district court. The district court for the related litigation has not yet construed the claim terms.” Pet. 7. The parties provided briefing regarding construction of “distributed mobile architecture (DMA).” Resp. 19–34; Pet. Reply 1–3; PO Sur-reply 11–14. But we do not need to construe “distributed mobile architecture (DMA)” to resolve this inter partes review. We thus do not construe this claim term. We also do not discern a need to construe explicitly any other claim language because doing so would have no effect on our analyses below of Petitioner’s asserted grounds and will not assist in resolving the present controversy between the parties. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those terms . . . that are in controversy, and only to the extent necessary to resolve the controversy.’”) (quoting Vivid Techs., Inc. v. Am.

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

      “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. For the reasons above, Petitioner does not establish by a preponderance of the evidence that the combined art teaches or suggests the final “when” recitation of claim 1.” slip op. at 29

      “Petitioner’s position is persuasive. We agree that documents from the Japanese Patent Office are self-authenticating official government documents. The technical issues regarding missing pages in the originally filed version of the document do not cause us to question authenticity.

      “Petitioner’s proposal is too broad. PO Resp. 8. For example, a person who merely installs solar panels for three years (satisfying “professional experience in solar energy”) while having some familiarity with module manufacturing would not be of ordinary skill in the design aspects of the ’060 patent as, for example, reflected by the claims at issue and the ’060 patent’s text and figures. 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). When assessing relevant experience, research work done for a university (beyond mere classroom study) would have been just as valuable as research work done for a corporation. Also, ordinary skill in the art could be demonstrated by work that requires understanding of the ’060 patent’s field even if not “designing, developing, and/or researching” in the field itself We, thus, determine that a person of ordinary skill in the art of the ’060 patent would have been someone with a bachelor’s degree in electrical engineering, applied physics, or the like, and at least two years of (a) experience designing, developing, and/or researching in the field or (b) experience in solar energy that required an understanding of the ’060 patent’s field.

For purposes of this proceeding, “speaker-independent speech recognition device” means “speech recognition device that recognizes spoken words without using predefined voice patterns.” This is consistent with the ’431 patent’s statement (relied on by both parties) that “[t]he voice browsing system recognizes naturally spoken voice commands and is speaker-independent; it does not have to be trained to recognize the voice patterns of each individual user.
