      “Under 35 U.S.C. § 324(a), a post-grant review may be instituted only if “the information presented in the petition . . . demonstrate[s] that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” Post-grant review is available for patents that issue from applications that at one point contained at least one claim with an effective filing date on or after March 16, 2013. See Leahy-Smith America Invents Act, Pub. L. No. 112-29, 125 Stat. 284 (2011) (“AIA”), §§ 3(n)(1), 6(f)(2)(A). Upon considering the arguments and evidence, we conclude that the information presented shows it is not more likely than not that at least one challenged claim of the ’174 patent is unpatentable.” slip op. at 2

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “For purposes of this Decision, we adopt the level of ordinary skill in the art articulated by Petitioner because, based on the current record, it is consistent with our review and understanding of the technology and descriptions in the ’174 patent and prior art of record. Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). We note, however, that our analysis below would be the same regardless of whether we adopt Petitioner’s or Patent Owner’s proffered level of skill in the art.” slip op. at 11

    • Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededDecided for petitioner

      “Petitioner and Patent Owner agree that no claim terms need construction. Pet. 14; Prelim. Resp. 6. After reviewing the evidence and arguments presented by the parties, we determine that it is not necessary to expressly construe any claim terms because doing so would not change the outcome of our analysis below. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (noting that “we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy’”) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng'g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)).” slip op. at 12

      “of Choi to support its argument that an ordinarily skilled artisan would have understood Choi’s infrared lamp housing to define a concave shape as claimed. See Pet. 61–62. With only this explanation and evidence from Petitioner and Dr. Jenson, however, we cannot not discern how these portions of Choi would have so apprised an ordinarily skilled artisan. For example, the side view of the infrared lamp housing, illustrated in Figure 5 reproduced below, shows the housing having a convex, rather than concave, shape. See Ex. 1008, Fig. 5. Furthermore, paragraphs 20 and 48 refer to the housing’s “circular” shape and outer periphery and also “tubular” shape. See id. ¶¶ 20, 48. But these descriptions, either alone or together with Figure 5, also do not support adequately a finding that Choi’s housing is concave. Choi’s teachings in paragraphs 20 and 46 regarding the lamp housing guiding or directing infrared light from the lamp to irradiate the skin of a user, without more, are similarly deficient. See id. ¶¶ 20, 46. And although Dr. Jensen appears to equate “concave” with “inner circular,” he does not provide the basis for his testimony or explain what “inner circular” means, particularly in the context of distinguishing a convex shape from a concave shape. See Ex. 1002 ¶ 197. Accordingly, we determine there is insufficient evidence to support Petitioner’s conclusory statements that an ordinarily skilled artisan would have understood Choi’s infrared lamp housing to define a concave shape as claimed.” slip op. at 23

First, the paragraph explicitly describes a particular feature that is different from TCP: the ITP information may be in locations other than those specified by a particular version of TCP. Appl. ’454 ¶ 80.

      “The test for written description “requires an objective inquiry into the four corners of the specification from the perspective of a person of ordinary skill in the art.” Ariad Pharms., Inc. v. Eli Lilly & Co., 598 F.3d 1336, 1351 (Fed. Cir. 2010) (en banc). The specification must clearly allow persons of ordinary skill in the art to recognize that the inventor invented what is claimed and “reasonably” convey to those skilled in the art “that the inventor had possession of the claimed subject matter as of the filing date.” Id.

    The Board denied institution because Morris was not prior art: claims 1 and 16 were entitled to the ’454 application’s priority date, so the obviousness challenge did not meet the institution threshold.

      “review under 35 U.S.C. § 324 and 37 C.F.R. § 42.4(a). We may not institute a post-grant review unless “the information presented in the petition . . . , if such information is not rebutted, would demonstrate that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” 35 U.S.C. § 324(a). Applying that standard, and upon consideration of the information presented in the Petition and the Preliminary Response, we determine that the information presented fails to demonstrate it is more likely than not that at least 1 of the challenged claims of the ’603 patent is unpatentable. Accordingly, we deny institution of post-grant review of claims 1–10 of the ’603 patent.” slip op. at 2

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “Patent Owner states that, for purposes of the preliminary response only, it does not challenge Petitioner’s definition of a person of ordinary skill in the art. Prelim. Resp. 19. Based on the current record and for the purposes of this Decision, we adopt Petitioner’s proposed description of the person of ordinary skill in the art. Furthermore, we find that the prior art of record reflects this level of skill in the art at the time of the invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001).” slip op. at 7

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed patent owner constructionDecided for patent owner

      “We agree with Patent Owner that “Interleukin 11 receptor α (IL- 11Rα) antibody” should not be construed to include antibodies that bind to IL-11Rα of non-human species but not to the human version of this protein because such a construction does not comport with the language of claim 1, which is clearly directed to treating a human subject. See Pause Tech. v. TiVo, 419 F.3d 1326, 1331 (Fed. Cir. 2005) (rejecting interpretation of claim element that ignored “other language appearing later in the claim” in stating that ‘“[p]roper claim construction . . . demands interpretation of the entire claim in context, not a single element in isolation.’”) (citing Hockerson– Halberstadt, Inc. v. Converse Inc., 183 F.3d 1369, 1374 (Fed.Cir.1999)). Construing this term to include antibodies that bind solely to non-human IL- 11Rα would be inconsistent with a claim directed to treatment of a human. Accordingly, for purposes of this decision, we construe “Interleukin 11 receptor α (IL-11Rα) antibody” to mean “any natural or synthetic, monoclonal or polyclonal antibody made using any animal system including phage, or fragment or derivative thereof, that binds to human IL-11Rα.”” slip op. at 9

      “We agree with Patent Owner that Petitioner appears to have overlooked the ’603 patent Specification’s disclosure of anti-IL-11Rα antibodies. Specifically, the ’603 patent lists “monoclonal antibody clone 025 (Sino Biological), clone EPR5446 (Abcam), clone 473143 (R & D Systems), clones 8E2 and 8E4 described in US 2014/0219919 A1 [Edwards] and the monoclonal antibodies described in Blanc et al (J. Immunol Methods. 2000 Jul. 31; 241(1–2); 43–59).” Ex. 1001, 18:41–46; Ex. 1003 ¶ 176.6 Edwards, which Petitioner relies on for its obviousness and anticipation grounds, is directed to antibodies “that bind to IL-11Rα and neutralize IL-11 signaling.” Ex. 1008 ¶ 13. Table 1 of Edwards lists clones 8E2 and 8E4 and sixty-three other antibodies (including variants of 8E2) as “exemplary IL-11Rα-binding proteins.” Id. ¶ 362. Table 1 of Edwards also includes the sequence ID numbers for the heavy and light chains of the variable regions of each of these sixty-five clones and the amino acid sequences for each are disclosed in the sequence listing.
