    “Patent Owner did not dispute that the combined teachings of Kumada and Debladis ’120 disclose each limitation of claim 1. Patent Owner, however, did dispute Petitioner’s proposed reasons for combining Kumada and Debladis ’120, and argues that Debladis ’120 is not analogous art. PO Resp. 36–61. The Federal Circuit stated that substantial evidence only supports the conclusion that a POSA would have been motivated to combine the teachings of Kumada and Debladis ’120. The factual record and Willis’s concession on appeal conclusively establish that the cost of copper was a known problem in the art, Debladis ’120 (and Kumada) helped address that issue, and Willis has not disputed that combining the teachings of Kumada and Debladis ’120 was within the skill of an ordinary artisan. Nothing more is required to establish a motivation to combine. Given that Willis has conceded that the combination of Kumada and Debladis ’120 disclose all the limitations in claim 1, we reverse the Board’s patentability determination as to that claim and vacate the Board’s judgment as to the remaining claims of the ’037 patent.

    “In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

Neither party argues that the outcome of these cases would differ based on our adoption of any particular definition of the level of ordinary skill in the art. Considering the subject matter of the ’626 patent, the background technical field, the prior art, and Petitioner’s proposed and undisputed definition of the skilled artisan, we apply the level of skill set forth above, which is consistent with the testimony of Mr. Fennell (Ex. 1003 ¶¶ 12–15).” slip op. at 20

    “But Patent Owner then urges us to narrow the meaning of “portion” itself such that “channel-shaped portion” requires “all portions of the hanger which directly bound the channel that receives the structural component.” PO Resp. 19 (emphases added). Patent Owner argues the Specification makes this “clear.” Id. (citing Ex. 1001, 2:28–31). Contrary to Patent Owner’s arguments (PO Resp. 19), we find no support in claim 1 to further narrow the interpretation of “portion” in “channel-shaped portion” to mean every portion of the hanger which directly bounds the channel that receives the structural component. See Ex. 1001, 12:14–36 (claim 1). We, like Petitioner, similarly find no support in the Specification or limited prosecution history (see Pet. 5–6), and Patent Owner does not direct us to any, showing that the inventor acted as its own lexicographer or disavowed any claim scope to allot this narrowed interpretation to the subject limitation. See Pet.

Further, as argued by Petitioner (Pet. Reply 4–5), Patent Owner’s proposed construction limiting “portion” to “all portions” of the hanger that “directly bound the channel that receives the structural component” could cause the “channel-shaped portion” on the same physical hanger to change depending on which type of structural component an installer were to choose to use in construction: Patent Owner’s claim construction improperly focuses on the wall assembly intended to be used with the recited hanger. The claims, however, are directed to a hanger, not a wall assembly. When assessing what part of a hanger constitutes a “channel-shaped portion” and an “extension portion,” [the skilled artisan] would consider the physical features of the hanger itself and the natural divisions between those features. [The skilled artisan] would not assess the claim language and its application to the prior art by speculating how an installer might later install the hanger with a joist or an entire wall assembly, which may differ from installation to installation.

    “Petitioner argues, inter alia, that Yamaguchi teaches a joist hanger with an extension portion defining a space between its back flange and channel-shaped portion, and Bundy teaches to size a space created by an extension portion of its joist hanger to receive two layers of ⅝-inch-thick drywall between its back flange plane and channel-shaped portion. Pet. 16–18 (citing 1003 ¶¶ 75–78; Ex. 1007, 5:16–18, Fig. 1; Ex. 1041 (“Perspective View”; “Usage View”)); see id. at 17–18 (discussing “advantages” of two layers of 5/8" drywall as “fire resistance in a fire separation wall”). Petitioner argues the skilled artisan “would have been motivated to receive drywall between Yamaguchi’s back flange and channel-shaped portion to provide a shielded fire resistant wooden frame wall.” Pet. 18 (citing Ex. 1003 ¶¶ 78–79; Ex. 1007, 2:10–24); see id.

Petitioner concludes: This modification to Yamaguchi would have been nothing more than applying a known technique (Bundy’s spacing a hanger seat from a wall frame by distance sufficient to accommodate two 5/8”-thick-drywall sheets for fire resistance) to a similar device (Yamaguchi’s hanger having a spacing of indeterminate length) to obtain the predictable result of a firewall hanger having a space between its channel-shaped portion and a wall frame large enough for receiving drywall therebetween, thereby “protect[ing] the structural members of a building.” Pet. 18 (citing Ex. 1007, 5:18–20; Ex. 1003 ¶ 80). Petitioner argues the skilled artisan would have had a reasonable expectation of success in modifying Yamaguchi as discussed above, “because doing so would still allow Yamaguchi’s hanger to perform its intended function of securing a joist to a wall.” Pet. 18 (citing Ex. 1041, 1; Ex. 1003 ¶ 81). Petitioner argues, “[r]ecognizing that Yamaguchi’s and Bundy’s hangers are constructed from sheet metal,” the skilled artisan “would have understood how to modify the size of Yamaguchi’s extension portions to accommodate two layers of 5/8”-thick-drywall while still allowing Yamaguchi’s hanger to secure a joist’s end to a frame wall.” Pet. 18–19 (citing Ex. 1003 ¶¶ 81–83; Ex. 1007, 4:47–51); see id. at 19–20 (discussing that although “Yamaguchi’s described setting is a sill plate,” the skilled artisan “would have been motivated to use Yamaguchi’s hanger on a wood frame wall in particular so that sheathing could be installed in the space behind the joist as taught by Bundy” (citing Ex. 1003 ¶¶ 81–82)).

Patent Owner cites no evidence of how the skilled artisan would have understood the combined teachings of Yamaguchi and Bundy, or how such an understanding would support Patent Owner’s attorney arguments. Indeed, Patent Owner did not file any expert testimony in any of the three subject cases, despite that we must resolve the legal question of obviousness on the basis of underlying factual determinations, particularly the scope and content of the prior art and any differences between the claimed subject matter and the prior art from the vantage point of the skilled artisan.

Here Petitioner does not expand on a position from the Petition that Patent Owner criticizes based on the merits of the contentions. Rather, Petitioner supplements its conclusory assertion that a “mining processor” is necessarily present in CryptoKube’s spondooliestech SP35 servers (Pet. 23, 25 (citing Ex. 1006, 1–4)) with its new assertion that that “a combination of an ASIC chip and a controller would meet the ‘mining processor’ limitation.” Pet.

  Claims 1–19 are unpatentable because the ’201 patent lacks written description support for the claimed genus of CRF1 receptor antagonists under § 112(a).

  • Disclosure Requirements (§112) › Written description (Ariad)Written description inadequateUnpatentable

    “[A] sufficient description of a genus instead requires the disclosure of either a representative number of species falling within the scope of the genus or structural features common to the members of the genus so that one of skill in the art can “visualize or recognize” the members of the genus. Id. at 1350 (citing Regents, 119 F.3d at 1568–69). Moreover, “an adequate written description requires a precise definition, such as by structure, formula, chemical name, physical properties, or other properties, of species falling within the genus sufficient to distinguish the genus from other materials.” Id. (citing Regents, 119 F.3d at 1568 (quoting Fiers, 984 F.2d at 1171)). Furthermore, “functional claim language can meet the written description requirement when the art has established a correlation between structure and function.” Id. (citing Enzo Biochem, Inc. v. Gen-Probe Inc., 323 F.3d 956, 964 (Fed. Cir. 2002) (quoting 66 Fed. Reg. 1099 (Jan. 5, 2001))). “[M]erely drawing a fence around the outer limits of a purported genus is not an adequate substitute for describing a variety of materials constituting the genus and showing that one has invented a genus and not just a species.” Id.” slip op. at 42

  • Skill levelSkill level petitioner adoptedDecided for petitioner

    “According to Petitioner, a person of ordinary skill in the relevant art (“POSA”) “would have a medical degree or a Ph.D. in a field related to endocrinology, and would have knowledge of hormone regulation and disorders, as well as knowledge of the treatment regimens employed to treat such disorders . . . [and] would also have at least three years of experience conducting research concerning endocrine disorders, including CAH or other adrenal disorders.” Pet. 26–27 (citing Ex. 1005 ¶ 34 (Dr. Carey Declaration)). Patent Owner does not expressly contest this definition of a person of ordinary skill in the art in its Response. Because Petitioner’s definition of a person of skill in the art appears commensurate with the level of skill reflected in the asserted art in this case as well as the ’201 patent itself, see, e.g., Exs. 1024, 1025, 2003, 2004, 2005, we apply Petitioner’s proposed level of ordinary skill in the art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (stating prior art itself can reflect the appropriate level of ordinary skill in the art). C.” slip op. at 22

    “For these reasons, we do not find persuasive the testimony of Patent Owner’s expert, Dr. Dobs, that: By describing adjustments of dosing protocols to achieve an A4 reduction from baseline, and describing this use of tildacerfont as just one embodiment of the claimed use of the entire well-known, well-characterized, and discrete class, the specification reasonably conveyed to a POSA that the invention extended to the particularly claimed use of the entire recited class. Ex. 2014 ¶ 82. On the contrary, far from being a “well-known, well-characterized, and discrete class” the prior art teaches a heterogeneous assembly of different classes of small molecule CRF1 receptor antagonists (Type I, Type II, and “atypical”) displaying a very considerable variety of structures, both in terms of the core pharmacophore (e.g., monocyclic, bicyclic, tricyclic, phenolic, cyclohexyl amide, etc.) as well as in the various side groups. Moreover, the challenged claims recite only “a CRF1 receptor antagonist or a pharmaceutically acceptable salt thereof,” the scope of which also encompasses the much larger (and, according to Williams) much more effective large-molecule (peptide) CRF1 receptor antagonists, about which the Specification is entirely silent. See Ex. 1029, Abstr., 1065. Furthermore, despite Dr. Dobs’ testimony that “[t]he [prior art] references explain the typical CRF1 antagonist consists of a core nitrogen heterocycle with an aryl substituent adjacent to the core nitrogen atom and a branched alkyl group attached at the opposite end of the core,” Dr. Dobs also acknowledged that the “atypical CRF1 receptors depicted in Figures 11 and 12 of Williams had different structures, and lacked the nitrogen heterocyclic core.” Ex. 1042, 127:9–14, 130:13–131:16; see also Ex. 2014 ¶ 83. Additionally, Petitioner’s expert, Dr. Cutler, testified, by way of example, in his Reply Declaration that two of the ‘“first-generation CRF1 antagonists’ identified in Figure 1 of the Williams article do not fall within the Figure 2 structure Dr. Dobs relies upon.” Ex. 1047 ¶ 93.

For these reasons explained above, Petitioner’s Motion to Exclude Dr. Dobs’ written description opinions in paragraphs 20 and 75–87 of Exhibit 2014 is denied.” slip op. at 11

    “To the extent that Dr. Dobs has admitted that she is “not comfortable with chemical terminology”; “could not answer questions regarding the chemical structures in the prior art articles”; “did not know whether CRF1 receptor antagonists contained the structural features she deemed ‘essential’ in her Declaration”; and “agreed that tildacerfont has structurally unique features” (see Ex. 1038, 52–53, 125–126, 126–128, 128–130), we will weigh her testimony regarding those matters accordingly.
