“We are not persuaded by Petitioner’s contention that we should disregard Dr. Naumovski’s testimony because she may have taken a leave of absence from work for a couple of years. The record supports that Dr. Naumovski not only meets the requirements of the person of ordinary skill in the art, but also appears to have relevant knowledge with respect to Gynostemma pentaphylum (“GP”) saponins. See Ex. 2015 (Appendix A). related field, and at least two years of experience using techniques for extraction and characterization of plant-based materials.” PO Resp. 11 (citing Ex. 2015 ¶ 74). Because there are more than 400 species of plants that contain saponins, Patent Owner disagrees that a person of ordinary skill in the art would be familiar with the structure and utility of saponins. Id. The level of skill in the art is a reference point for gauging what would have been obvious based on the reference disclosures. See Okajima, 261 F.3d at 1355. In other words, the lens of the level of ordinary skill in the art does not change a prior art’s disclosure, though it may change one’s understanding of what is disclosed. Patent Owner, however, does not explain how its definition provides a reference point that would meaningfully alter the Petition’s assertions of obviousness. For purposes of this decision, we analyze the asserted prior art with respect to the level of skill set forth by Petitioner, but there would be no difference in the outcome of this Decision if we were to apply the level of skill in the art set forth by Patent Owner.

“during the full trial, we determine that Petitioner has not shown by a preponderance of the evidence that applying the methods of Kim 460 to the G. pentaphyllum starting material of Razmovski necessarily results in the damulin levels as claimed. We agree with Dr. Naumovski’s explanation that the use of an impure damulin B standard containing a double peak renders the results as shown in Exhibit 1013 unreliable. Ex. 2015 ¶¶ 141–143, 162–173; see Ex. 2007. Dr. Naumovski further explains that the use of an impure standard would require the application of a correction factor, but this correction factor would need to be reassessed as the purity of the standard decreases over time. See Ex. 2015 ¶ 166. As Dr. Naumovski explains that applying a correction factor to the linear regression would result in a shallower slope. Ex. 2015 ¶ 165 (citing 2006, 71:12–73:5; 99:2–9). “Reducing the calibration curve slope increases the amount of damulin B calculated from the experimental extracts.” Ex. 2015 ¶ 165. However, in the Experimental Report-1 the same correction factor for the damulin B standard was used to” slip op. at 41

“Petitioner requests construction of the terms “an effective amount for improving or treating the metabolic syndrome,” which is found in claims 11–13, as meaning “an amount that produces any measurable amount of improvement in the metabolic syndrome” (Pet. 13–15 (citing Ex. 1003 ¶ 91)) and “[a] pharmaceutical composition for improving and treating a metabolic syndrome, comprising at least one of at least 0.7% damulin A and at least 0.5% damulin B . . . and a pharmacologically acceptable carrier or excipient,” which is found in claim 8, as meaning “a pharmaceutical composition that includes an extract with 0.7% and 0.5% of damulin A and damulin B[, respectively,] along with a carrier or excipient” (id. at 15–16 (citing Ex. 1002, 64–65, 251–52, 280; Ex. 1001, 12:15–67, Table 2)).

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“Obviousness does not require absolute predictability of success . . . all that is required is a reasonable expectation of success.” In re Droge, 695 F.3d 1334, 1338 (Fed. Cir. 2012) (quoting In re Kubin, 561 F.3d 1351, 1360 (Fed. Cir. 2009) (citing In re O’Farrell, 853 F.2d 894, 903–04 (Fed.Cir.1988)); Intelligent Bio-Systems, Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359 (Fed. Cir. 2016) (explaining that the expectation of success issue involves a showing of “a reasonable expectation of achieving what is claimed”) (emphasis added). Here, Petitioner relies on Kim 460 to show that heating ginseng, which contains the ginsenosides Rb1, Rb2, Rc, Rd, Rg3, and Rg5, results in a teaches that ginseng with the higher Rg3 and Rg5 content is 50-fold more potent in their vasodilation studies than the non-treated samples. Razmovski teaches that G. pentaphyllum contains over 100 saponins and eight of those saponins are the same as protoparaxadiol-type ginsenosides Rb1, Rc, Rb3, Rd, F2, Rg3, malonyl-Rb1, and malonyl-Rd that are found in P. ginseng. Ex. 1007, 4. Knowing that G. pentaphyllum also contains ginsenosides Rb1, Rb2, Rc, Rd, Rg3, and Rg5, we find Petitioner’s conclusion that heating a G. pentaphyllum extract that contains these ginsenosides would similarly increase the ginsenoside levels of Rg3 and Rg5 is a reasonable inference from the cited references. Based on the teachings in Kim 460, we agree with Petitioner that it would have been reasonable to expect that the same source material, although derived from a different plant, would behave similarly to heat treatment. See Pet. 24. Because G. pentaphyllum is a less expensive starting material, we also agree with Petitioner that there is sufficient motivation to substitute G. pentaphyllum for ginseng in the methods of Kim 460. slip op. at 29

“We conclude that Petitioner’s arguments are insufficient to meet its burden of showing, by a preponderance of the evidence, that Goldfarb ’267 anticipates, or renders obvious, the limitation of proposed substitute claim 11 reciting “advancing the end of the first-clip arm and the end of the second-clip arm out of the delivery tube before advancing the support portion out of the delivery tube” merely requires advancing the ends of the clip arms out of the delivery tube “before advancing the support portion out of the delivery tube.” Moreover, Petitioner’s arguments are not persuasive with respect to proposed substitute dependent claims 12–20 due to their dependence from, and incorporation of, the limitations of proposed substitute claim 11. See Supp. Mot. Amend. 1, Reply Supp. Mot. Amend. 1. We therefore conclude that these proposed substitute claims are similarly neither anticipated by, nor obvious over, Goldfarb ’267. III. CONCLUSION We GRANT Patent Owner’s non-contingent Motion to Amend and Supplemental Motion to Amend, canceling original claims 1–10 and replacing them with substitute claims 11–20. Additionally, for the foregoing reasons, and after having analyzed the entirety of the record and assigning appropriate weight to the cited supporting evidence, we determine that Petitioner has failed to establish, by a preponderance of the evidence, that proposed substitute claims 11–20 are unpatentable.” slip op. at 57

(US 7,563,267 B2, July 21, 2009) (“Goldfarb ’267”) (Ex. 1005). 5 Petitioner refers to Goldfarb’s ’267 disclosure of a further alternative at Ex. 1005 col. 27 ll. 57–60 as Embodiment A. See Pet. 19.

“is described in Goldfarb ’267 as plainly a single, unitary structure and, as such, each portion argued as separate elements by Petitioner (i.e., male element (yellow), female element (green), coupling member 19 (blue) and flexible arms 19A and 19B (dark blue)) together form a solid, single component. Thus, all of the “elements” described by Petitioner as being “separate” are in fact a single unit that: (1) bears the weight of the fixation device during delivery; (2) absorbs and transfer the axial and rotational forces imposed by the shaft 12; and (3) holds the device in the correct orientation. Petitioner points to no disclosure of Goldfarb ’267 that suggests these elements act independently or separately to perform the functions of the unitary component, nor can we discern any such disclosure. We therefore find that Petitioner’s argument that only the “male element” portion of coupling member 19 constitutes the “support portion” recited in proposed substitute claim 11 is an arbitrary and unduly restrictive interpretation of the reference’s disclosure. This is particularly true given that Petitioner points to no portion of the male element of coupling member 19 performing a supporting function that is not shared by the other elements of coupling member 19. We conclude that the better understanding of the reference is that the entirety of coupling member 19 (including flexible arms 10A and 19B11) constitutes an analogous support portion, as recited by substitute claim 11, because it provides a unitary structure that performs the supporting functions enumerated by Petitioner.” slip op. at 41
