      “The existence of a published abstract that would have allowed one skilled in the art exercising reasonable diligence to locate the foreign patent application and the fact that the application was classified and indexed in the patent office, were central to the Wyer court’s conclusion that the application was “publicly accessible.”” slip op. at 35

      “inherency, then the assertions of obviousness are mere conclusory statements. We are unable to recognize any proffered reasoning underlying the assertions of obviousness. “[Challenges] on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006). As yet another possible alternative, Petitioner may be basing its case on improper hindsight by relying on and quoting the Specification of the ’240 patent in its obviousness analysis. See Pet. 27. That, too, is unpersuasive. Regardless as to its theory of the case, we determine that Petitioner has failed to explain sufficiently why the claimed heat pipe having a configuration of two plates having bonded together circumferential edge lips would have been obvious. Accordingly, Petitioner has not shown by a preponderance of the evidence that claim 12 is unpatentable over Morikawa alone.” slip op. at 55

R. Evid. 104, 401). As set forth in section II.D, above, the evidence of record leads us to an entirely different conclusion regarding Nakamura’s prior art status.

Reply 15 (citations omitted). And though Patent Owner attempts to distinguish Queen 1990 as describing “a consensus framework from many human antibodies,’ not all as in the ’213 patent,’” it presents no argument as to why we should interpret the claim in this manner. 11 Kabat et al., Sequences of Proteins of Immunological Interest: Tabulation and Analysis of Amino Acid and Nucleic Acid Sequences of Precursors, V- Regions, C-Regions, J-Chain, T-Cell Receptor for Antigen, T-Cell Surface Antigens β2-Microglobulin, Major Histocompatibility Antigens, Thy-1 Complement, C-Reactive Protein, Thymopoietin, Post-Gamma Globulin, and α2-Macroblobulin, 41–175 (4th Ed. 1987).

Moreover, in a parallel proceeding involving the same patent, Patent Owner did not dispute that the reference to “all sequences” in the patent, “refer[s] to all known sequences and there’s no dispute . . . that was really synonymous with Kabat 1987.” See IPR2017-01374 Paper 82, Tr. 15:4–16:4; see Ex. 1202 ¶ 157; Ex. 2105 ¶¶ 24–25; Ex. 2107 ¶¶ 18–19; Ex. 1198, 56:20–61:24; Ex. 1199, 27:14–28:13, 29:25–36:2, 57:1–58:6, 115:7–17, 165:17–169:9.

      “lacks immunogenicity compared to a non-human parent antibody upon repeated administration to a human patient.” In our institution decision, we determined that this claim language “refer[s] to a humanized antibody having reduced immunogenicity in a human patient as compared to its non-humanized parent antibody.” Dec. 10–12. Neither party disputes this interpretation. See PO Resp. 19; Pet. Reply 5–6. Consistent with claim 63’s express comparison between the immunogenicity of the claimed humanized antibody and that of its non-human parent, the Specification states that one object of the invention is to “to provide methods for the preparation of antibodies which are less antigenic in humans than non-human antibodies but have desired antigen binding and other characteristics and activities.” Ex. 1001, 4:24–28. The Specification similarly states that embodiments within the scope of the claims have “low immunogenicity,” or are designed to “minimize the potential immunogenicity of the resulting humanized antibody in the clinic.” Id. at 52:54–58, 61:56–61. Moreover, with reference to claim 63 in particular, Patent Owner points to the ’272 application as “explain[ing] that the purpose of humanizing antibodies using its consensus sequence approach is to reduce immunogenicity versus the non-human parent antibody. (Id., 6:24–30, 84:24–30.).” Prelim.

In light of the above, we do not alter our prior determination that “[a] humanized antibody which lacks immunogenicity compared to a non-human parent antibody upon repeated administration to a human patient,” refers to a humanized antibody having reduced immunogenicity in a human patient as compared to its non-humanized parent antibody.” slip op. at 14

Here, Queen 1989 recognizes the need to substitute framework residues in order to “reduce immunogenicity while retaining high binding affinity.” See Ex. 1534, 3.

      “Level of Ordinary Skill in the Art In the Decision to Institute, we found the parties’ proposed definitions of a person of ordinary skill for the ’213 patent are similar. Dec. 10 (citing Pet. 12; Prelim. Resp. 17). We adopted Patent Owner’s proposed definition that “[a] person of ordinary skill for the ’213 patent would have had a Ph.D. or equivalent in chemistry, biochemistry, structural biology, or a closely related field, and experience with antibody structural characterization, engineering, and/or biological testing, or an M.D. with practical academic or industrial experience in antibody development.” Id. at 10–11. During trial, the parties did not dispute this finding. Having considered the complete record developed at trial, we see no reason to change our assessment. We further note that, in this case, the prior art itself demonstrates the level of skill in the art at the time of the invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown”) (quoting Litton Indus.

      “In the Decision to Institute, we agreed with Patent Owner that the ’213 patent expressly defined “consensus human variable domain,” which appears in claims 4, 33, 62, and 69, to mean “a human variable domain which comprises the most frequently occurring amino acid residues at each location in all human immunoglobulins of any particular subclass or subunit structure.” Dec. 7; Ex. 1001, 11:32–38. During trial, the parties did not argue otherwise, and we see no reason to change our position as to claim construction. We, however, clarify that “all” in the consensus of “all human immunoglobulins” is not in the literal sense. Indeed, counsel for Patent Owner acknowledged that the term refers to “all reasonably available[,] all known at the time of the invention.” Tr. 47:21–48:5. Dr. Wilson, the expert witness for Patent Owner, testified that the consensus sequence of the ’213 patent was “derived from ‘all’ known antibody sequences of any particular subclass or subunit structure.” Ex. 2041 ¶ 207 (emphasis added); see also PO Resp. 52 (arguing the same); Ex. 1140, 59:22–60:1 (Dr. Carter testifying that the consensus sequence, as defined in the ’213 patent, “only describes what was known at that time or it’s only available sequences at that -- at that time”); Ex. 1142, 35:9–16 (Dr. Presta explaining that the consensus sequence of the ’213 patent had the most common residue at every position “for the sequences that were available”). And evidence of record shows that at the priority date of the ’213 patent, the sequences that were listed in Kabat 1987 “were the sequences available.” Ex. 1142, 35:9–20; see also Ex. 2016 ¶ 25 (Kabat 1987 “collected known sequence data of antibodies”); Ex. 1140, 60:13–25 (Dr. Carter explaining the consensus sequence was derived from Kabat 1987, which is what was available at the time of the ’213 patent); Ex. 1142, 27:19–25 (Dr. Presta stating that “Elvin Kabat had taken all known human/mouse/rabbit antibody sequences, published them in a government publication, and that there were human subgroups of sequences within the heavy and the light chains”).

Patent Owner’s construction limits “low power” to signals having a “limited transmission range,” but provides no guidance of what “limited” means, or what its boundaries might be. Petitioner argues correctly that Patent Owner’s construction fails to address questions its proposed construction raises, such as, what a ‘limited’ transmission range means and how ‘limited’ the range must be (i.e., what the range’s distance should be), whether the transmission range depends on the particular system or application, and whether other factors should be considered in determining whether the transmission range is limited.” slip op. at 14

      “Notably, Petitioner says these contentions are “further evidence” but does not explain how this evidence is to be used to buttress Cunningham’s disclosure or how it is to be combined with Cunningham’s disclosure. Specifically, given the limited contentions in the Petition detailed above, Petitioner does not explain how Energy Management Services or the “routines” described in the Provisional send control signals from the computer to the actuator as required by the claims. For example, even if we to accept that the “Williams Network Control Center” creates control signals as required by the claim Petitioner has not explained how those signals are translated from network transfer protocol to RF signals and then translated to an analog signal that can be used at an actuator.

      “Patent Owner’s argument is inapposite, as it is premised on reading a limitation into the claims, namely that the information encoded in the RF signal must be translated in real time. Further, we agree with Petitioner, that even under such an erroneously narrow construction, Cunningham would meet the limitation. In that regard, Petitioner argues that, “although Cunningham discloses sending cumulative data readings, individual signals from the sensor are identified by the gateway and this information is then transmitted (with transmitter identification information) to a computer on the WAN.” Reply 6 (citing Ex. 1046 ¶¶31–32; Ex. 1004, 31:6–28). Petitioner argues, and we are persuaded, that “Cunningham explains that the ‘most current cumulative reading’ is the current absolute ‘reading’ (i.e., information signal) from the sensor (Ex. 1004, 13:44–46) and that two cumulative readings can be used to ‘interpolate’ and ‘recover’ a missed reading (i.e., a signal from the sensor).” Reply 7 (citing Ex. 1004, 13:44–56; 31:6–27; Pet. 75; Ex. 1002 ¶¶115, 152; Ex. 1046 ¶32). We are persuaded that Cunningham discloses this limitation. Lastly, claim 32 also recites “a computer configured to execute at least one computer program that formats and stores select information responsive to the electrical signal for retrieval upon demand from a remotely located device.” To meet this limitation, Petitioner accurately points out that “Cunningham discloses that[,] in response to receiving information from the sensor interface module through the data collection modules, the host module compiles the information into a user specified readable format and stores it for later retrieval upon demand from a customer computer or workstation.” Pet. 83 (citing Ex. 1004, 7:19–27, 44:12–41, 44:53–64, 46:44–61, 47:44–54, Ex. 1002 ¶¶138–140).

Petitioner argues that its proposed construction is supported by the claim language and specification of the ’806 patent. Id. at 17–19.

The dispute between the parties focuses on whether a media presentation can consist of only a single file or must have multiple segments. Pet. 17–19; PO Resp. 11. The ’806 patent consistently uses the term “segment” to indicate that a media presentation is divided into multiple segments.

In contrast, the ’806 patent does not use the term “segment” to refer to a media presentation that consists of only a single file. Id. at 2:7–9.

      “construction against the prior art than it does to construction of the term itself. Patent Owner’s proposed construction, like Petitioner’s, does not, on its face, exclude RF protocol conversion. In this respect, we agree with Petitioner that Patent Owner is improperly attempting to read in additional limitations that go beyond claim 5’s broad recitation of a “transmitter . . . configured to encode the electrical signal.” See Paper 45, 3. As Petitioner further observes, the Specification of the ’661 patent refers interchangeably to data controller 324 (shown in Figures 3A–3E, not reproduced here) as “data formatter 324” (emphasis added), which “operates to form concise data packets.” Id.; Ex. 1001, col. 8, ll. 49–51. Petitioner’s proposed construction is thus consistent with the Specification. Patent Owner agrees that data controller 324 “encodes a physical condition into a function code,” but emphasizes that it does so “before getting converted by the RF transmitter.” Paper 44, 3. The distinction Patent Owner relies on to exclude RF protocol conversion from its proposed construction would improperly narrow the scope of the claim by implicitly adding a limitation that has no express basis in the claim. In re Prater, 415 F.2d 1393, 1404–05 (CCPA 1969) (“Nevertheless, ‘reading a claim in the light of the specification,’ to thereby interpret limitations explicitly recited in the claim, is a quite different thing from ‘reading limitations of the specification into a claim,’ to thereby narrow the scope of the claim by implicitly adding disclosed limitations which have no express basis in the claim.”).

      “Patent Owner does not advocate for a specific level of skill in its Response, but its expert, Kevin C. Almeroth, Ph.D., articulates a level of skill similar to Petitioner’s proposal. Ex. 2009 ¶ 75. Specifically, Dr. Almeroth opines that a person of ordinary skill “would have the equivalent of a four-year degree from an accredited institution (usually denoted as a B.S. degree) in computer science, computer engineering or the equivalent and experience with, or exposure to, computer networks and routing.” Id. In addition, according to Dr. Almeroth, a person of ordinary skill “would also have approximately two years of professional experience with computer networking, routing, and wireless networks. Id. And “[a]dditional graduate education could substitute for professional experience, while significant experience in the field might substitute for formal education.” Id. Given the similarity of articulations by the respective experts, and because our Decision does not depend on nuanced distinctions of the level of skill in the art, we adopt Dr. Almeroth’s more detailed articulation, but include electrical engineering as an additional alternative educational background, as indicated by Mr. Kinney.” slip op. at 15

      “We thus agree with Patent Owner that the rationale articulated by Petitioner is conclusory, and insufficiently supported. PO Resp. 30–31. On the record before us, it is more reasonable to construe “the transceiver identification information” as referring to something other than the identification information for the at least one wireless transmitter. For example, Patent Owner contends that “[o]ne skilled in the art, reading the plain text of claims 5 and 8, would easily recognize that the ‘transceiver’ referred to in claim 8 is the transmitter in claim 5 that is configured to both send and receive signals.” Id. at 33. Patent Owner provides support for this reading both by identifying disclosure in the Specification of the ’661 patent consistent with its position, and through testimony by its expert, Dr. Almeroth. Id. at 33–36 (citing Ex. 1001, Figs. 2, 3C, 3D, col. 6, ll. 3–8, col. 9, ll. 53–56, col. 10, ll. 32–34; Ex. 2009 ¶¶ 125–132). For example, Dr. Almeroth testifies that Mason’s AMR server “at most would need only some meter identification number and a meter reading.” Ex. 2009 ¶ 134. We credit this testimony, as well as Dr. Almeroth’s assertion that “[t]ransceiver identification information is extraneous for the needs of the AMR server in Cunningham and Mason.” Id. Ultimately, we need not resolve the construction issues, and the issue of whether claim 8 is indefinite is not before us. 35 U.S.C. § 311(b) (limiting inter partes review to “a ground that could be raised under section 102 or 103”). It is sufficient for us to determine whether Petitioner has put forth sufficient evidence to meet its burden of establishing that claim 8 would have been obvious over the combination of Mason, Shuey, and Cunningham.

      “c. “one or more additional wireless transmitters” Third, Petitioner combines the teachings of Shuey with those of Mason in addressing claim 5’s recitation of “one or more additional wireless transmitters.” Id. at 62–63. The claim requires that each such additional wireless transmitter is “electrically interfaced with a sensor and configured to receive the RF signal and retransmit the RF signal,” i.e., to act as a repeater. Ex. 1001, col. 19, ll. 22–24. As discussed above, Mason discloses that meter 12D is considered “inaccessible” with respect to node 18, and that another meter within the network may act as a repeater so that the inaccessible meter may still be contacted. Id. at col. 6, ll. 27–35. Petitioner cites Shuey for details regarding the information included in retransmission by meters acting as repeaters, and provides sufficient reason to effect the combination in light of Mason’s explicit reference to Shuey: “A POSITA would have been motivated to incorporate into Mason’s system Shuey’s teaching of a repeater that retransmits all of the claimed information, because Mason explicitly notes that Shuey’s system is a system for which Mason’s invention is particularly suited.” Pet. 58–59 (citing Ex. 1007, col. 6, ll. 35–38; Ex. 1002 ¶¶ 110–112).
