    “In an [inter partes review], the petitioner has the burden from the onset to show with particularity why the patent it challenges is unpatentable.” Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016) (citing 35 U.S.C. § 312(a)(3) (2012) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim”)). This burden of persuasion never shifts to Patent Owner. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015) (discussing the burden of proof in inter partes review). A claim is unpatentable under 35 U.S.C. § 103 if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence (1966). In analyzing the obviousness of a combination of prior art elements, it can be important to identify a reason that would have prompted one of skill in the art “to combine . . . known elements in the fashion claimed by the patent at issue.” KSR, 550 U.S. at 418. A precise teaching directed to the specific subject matter of a challenged claim is not necessary to establish obviousness. Id. Rather, “any need or problem known in the field of endeavor at the time of invention and addressed by the patent can provide a reason for combining the elements in the manner claimed.” Id. at 420. Accordingly, a party that petitions the Board for a determination of unpatentability based on obviousness must show that “a skilled artisan would have been motivated to combine the teachings of the prior art references to achieve the claimed invention, and that the skilled artisan would have had a reasonable expectation of success in doing so.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1381 (Fed.

    “On the record before us, however, Dr. Flatt’s assessment of the relative benefit one of ordinary skill in the art would have accorded the higher Ki of mono-substituted compound 3 as compared to the “much longer plasma half-life” of Dong’s bi-substituted compounds is at odds with Dong’s selection of bi-substituted compound 4 for clinical trials. See Ex. 1013, 670– 671 (Table 1). We are also skeptical of Dr. Flatt’s assertion that one of ordinary skill in the art would have recognized that Dong’s substitution of Aib for alanine at position 8 “would complement and work synergistically with liraglutide’s [other] properties,” including the fatty acylation of Lys26. See Ex. 1020 ¶ 181. In this respect, Patent Owner notes that, unlike liraglutide, Dong’s GLP-1 analogs were not acylated, whereas Knudsen 2001 counseled against N-terminal modifications in the context of acylation. Prelim. Resp. 28–30, 46 (citing Ex. 1011, 680–681). In addressing such combinations, Knudsen 2001 states, for example, that “Desamino His7 represents one of the more potent suggestions to a modification giving metabolic stability (81 ). Nevertheless, as seen when comparing 19 (687 pM) to 5 [liraglutide] (68 pM), considerably more potent compounds could be obtained by not modifying the N-terminus when a combination with acylation was desired.” Id. at 680. As such, we are unpersuaded on the record before us that one of ordinary skill in the art would have had a reasonable expectation that the Aib8 modification would be beneficial or otherwise “complement and work synergistically with” the acylated Lys26 of liraglutide or semaglutide.

    “Considering the record before us, Petitioner has not shown sufficiently that one of ordinary skill in the art would be motivated to make the required modification with a reasonable expectation of success. (4) Hindsight and Reasonable Expectation of Success One of ordinary skill in the art seeking to modify liraglutide would need undertake at least four discrete steps to arrive at semaglutide—some of which entail multiple options and decision points (e.g., the selection and placement of di-AEEA, and whether to replace, or add to, the existing γ-glu linker). As discussed above, we find Petitioner’s justification for these individual steps problematic. Taken as whole, and considering the vast number of modifications suggested in the art—and indeed, the large number of amino acids suggested as cites for modification—Petitioner has failed to meet its burden of demonstrating why a skilled artisan would have been motivated to make all of the identified substitutions and no others. See e.g., Ex. 1010, 4130 (Figure 3) (identifying amino acids available for derivatization (Ser18, Gln23, Lys26, Glu27, Lys34, and Arg36) or modification (Ala8)); Ex. 1011, 680–681 (identifying desamino His7 as “one of the more potent suggestions to a modification giving metabolic stability,”); Ex. 1012 at, e.g., 9:21-19:59; 192:30–60 (Table 1), 193:35–46 (disclosing numerous GLP-1 analogs, including those with greater half-lives or potency than liraglutide, and teaching that each could be further modified, including with amino acid substitutions and/or acylation at multiple positions, numerous the fatty and amino acids); Ex. 1013, 670–671 (disclosing that GLP-1 analogs bearing modifications at both positions 8 and 35 maintain efficacy but “have much longer plasma half-life than mono-substituted compounds”).” slip op. at 43

  • BurdenDecided for patent owner

    “As an initial matter, we find Petitioner has insufficiently addressed the issue of inherent anticipation by Dixon (or any other prior art) and has done so in a merely conclusory manner. There is no dispute that Dixon (as well as the other asserted prior art) discloses angiogenic eye disorder treatment using the same drug (aflibercept), at the same dose (2 mg), administered in the same way (intravitreal injection), and administered at the same dosing regimen (an initial, a secondary, and a tertiary dose), as required by all challenged claims. See generally Pet.; Prelim. Resp. Petitioner relies on these facts, and the results of a phase 2 clinical trial that followed a different dosing protocol (one not claimed) to establish that the results limitations of claims 1, 26, and 29 are inherent to the phase 3 clinical trials (VIEW 1 and 2) with a dosing regimen that is claimed. See Pet. 38–39. Petitioner calls the claimed results limitations mere newly discovered results of a known process. Id. (citing Montgomery, 677 F.3d at 1381). As Patent Owner identifies, it is not so simple. The evidence of the results of the VIEW 1 and 2 trials itself (found in the ’572 patent) shows that some, but not all, patients treated with the claimed dosing regimen achieved “a gain in visual acuity” as recited by claim 1, “a gain in visual acuity” that is “as effective” “as monthly administration of 0.5 mg of ranibizumab” as recited by claim 26, or “maintaining visual acuity” “as effective[ly]” “as monthly administration of 0.5 mg of ranibizumab” as recited by claim 29. See Ex. 1001, 13:5–38 (Table 1). As Patent Owner points out, the ’572 patent’s described studies 1 and 2, when following the claimed dosing regimen (2Q8), were not always effective treatments––achieving mere maintenance (as opposed to improvement or “gains”) of vision 95.1% and 95.6% (respectively) of the time. Id.; see Prelim. Resp. 34–37 (citing Ex. 1001, 13:8–27; Ex. 1014, 4, 6; Ex. 1030, 9; Ex. 2021 ¶¶ 109–111; Ex. 2022). Thus, the evidence shows that, although most would, about 4–5% of patients (or, possibly, an even higher number based on Patent Owner’s cited evidence––Ex. 1030, 9) would not see the gains in visual acuity required by claims 1 and 26 or the maintenance in visual acuity required by claim 29. It is well established that “[i]nherency . . . may not be established by probabilities or possibilities” and “[t]he mere fact that a certain thing may result from a given set of circumstances is not sufficient.” In re. Oelrich, 666 F.2d 578, 581 (CCPA 1981) (quoting Hansgirg v. Kemmer, 102 F.2d 212, 214 (CCPA 1939)).

    “Relating to the claim construction, the Federal Circuit found that patent at issue was “clear” that the tissue fibrosis, recited by the claim as arrested or regressed by the otherwise recited treatment, was not the same as and did not necessarily accompany the symptom of erectile disfunction (taught in and the focus of the relied-upon prior art), although the former (fibrosis) may frequently result in the latter (disfunction). Id. at 1059. The Federal Circuit held that the “arresting or regressing” clause was more than a mere statement of intended result, but was a limitation carrying patentable weight because the phrase was drafted as a part of a separate step of the method rather than of the preamble, the “arresting or regressing” language demanded efficacy, and the efficacy was linked to specific treatment minimum duration and dosage. Id. at 1060–61. The patients exhibiting these two issues were not necessarily the same. In part because the Board did not consider the arresting/regressing result limitation in its unpatentability analysis, the Federal Circuit agreed with the patent owner that the Board’s findings were insufficient. Id. at 1064, 1067. The Federal Circuit found that that prior art reference relied upon in the Board’s decision for teaching the claimed treatment, and also relied upon to link the condition of fibrosis with the symptom of erectile dysfunction, did not teach treating a population of patients suffering from erectile dysfunction only because of a fibrosis condition and, even though such patients may have had fibrosis, it was not certain; and further found that other cited prior art did not make certain a link between fibrosis and such dysfunction. Id. at 1065–66. This, the Federal Circuit found, was error. We find in agreement with Patent Owner that the results limitations of the challenged claims are limitations and must be given patentable weight for the same reasons arresting or regressing a tissue fibrosis was a limitation in Los Angeles Biomed. Similarly, here the claims are directed to expressly required results of the administration of aflibercept to patients at 2 mg at an initial dose, in at least one secondary dose 4 weeks later, and in at least one tertiary dose 8 weeks later. Therefore, we find that in claim 1, “wherein the patient achieves a gain in visual acuity within 52 weeks following the initial dose,” is a limitation. Further, in claim 26, “wherein the method is as effective in achieving a gain in visual acuity as monthly administration of 0.5 mg of ranibizumab by intravitreal injection in human subjects with age-related macular degeneration at 52 weeks following the initial dose,” is a limitation. And, in claim 29, “wherein the method is as effective in maintaining visual acuity as monthly administration of 0.5 mg of ranibizumab by intravitreal injection in human subjects with age-related macular degeneration at 52 weeks following the initial dose,” is a limitation.” slip op. at 17

    “Although it is certainly the case that an obviousness analysis may take into account the inferences and creative steps that a skilled artisan might glean from the teachings of the prior art (see, e.g., KSR , 550 U.S. at 418), one must be cognizant that “hindsight is not an available analytical mechanism to show obviousness.” See In re Omeprazole Patent Litig., 483 F.3d 1364, 1381 (Fed.

Without the guidance provided by the claims of the ’502 patent, it is difficult to conclude that Petitioner’s postulation as to a particular structure that results from combining the teachings of Lumidigm, Kotanagi, and Scharf is based on an objective assessment of what those teachings would have conveyed to a skilled artisan. It is clear from the Petition, however, that such structural configuration is necessary as the basis for Petitioner’s approach to arriving at the structural requirements of the claims.9 At the outset, we share Patent Owner’s view, and that of its declarant, Dr. Duckworth (Ex. 2002), that none of the prior art on which Petitioner relies discloses a convex protrusion with multiple openings or windows for multiple detectors. See, e.g., Prelim. Resp 28–29; Ex. 2002 ¶ 76. As discussed above, Petitioner attempts to arrive at such structure through a proposed amalgamation of prior art teachings that must include, for instance, arranging a convex protrusion with multiple openings or separate glass windows over Lumidigm’s optical sensors.

    “Although it is certainly the case that an obviousness analysis may take into account the inferences and creative steps that a skilled artisan might glean from the teachings of the prior art (see, e.g., KSR , 550 U.S. at 418), one must be cognizant that “hindsight is not an available analytical mechanism to show obviousness.” See In re Omeprazole Patent Litig., 483 F.3d 1364, 1381 (Fed.

    “specific citations to evaluate its assertions, Petitioner does not direct our attention to any portion of the Nordgren Declaration providing information on why the partial sequences disclosed by the references teach or suggest the claimed 90% sequence homology. Pet. 76, 79 (citing Ex. 1026 at VII.C, ¶¶ 247–269). For example, Dr. Nordgren’s assertion “a POSITA would anticipate natural genetic variation of PorkNW2/USA/2009 ORF2 would bring it within the scope of the Claim 1 genera” is not supported by substantial evidence. Ex. 1026 ¶ 256. Claim 1, for example, recites a PCV3 protein and does not recite partial proteins. Without knowing what portion of complete proteins are disclosed by the references, we are not persuaded that a person of ordinary skill in the art would have been able to predict the variation expected among a group of complete proteins to arrive at the claimed subject matter as is implied by Petitioner. Petitioner’s conclusory statements are insufficient to support a legal conclusion of obviousness. And while we agree with Petitioner that the protein sequences disclosed in the cited references do not necessarily have to be designated as PCV3 sequences, we determine that Petitioner has failed to meet its burden to demonstrate that any of the PCV3 deposit references teach or suggest the recited sequences within the claimed range. Pet. 79. Therefore, Petitioner has not met its burden in showing that every claimed element is taught by its cited references, and we need not reach Petitioner’s argument on motivation to combine.

A POSITA would also have practical knowledge of immunology, including how vaccine candidates are first identified and then subsequently developed.

Pet. 31–32.

See Pet. 31–32. However, Dorn does not disclose any weight percentage for dipropylene glycol pelargonate or any of the disclosed spreading agents. Petitioner instead relies on Dorn’s disclosure of plasticizers in amounts of 10 to 50%, preferably approximately from 25% to 45% by weight, to supply this disclosure. Pet. 41–42. In order for this argument to be persuasive, Petitioner must show that one of ordinary skill in the art would have been motivated to, and would have had a reasonable expectation of success in, substituting the plasticizers of Dorn with Miglyol 840 as disclosed in Reul.

    “Obviousness Analysis A claim is unpatentable under 35 U.S.C. § 103(a) if the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious at the time the invention was made to a person having ordinary skill in the art to which the subject matter pertains. See KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations, primarily: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) objective evidence of nonobviousness.

The evidence of device 900 and claims of collateral estoppel do not remedy this deficiency. In the absence of such evidence, Petitioner has failed to “identif[y], in writing and with particularity, . . . the evidence that supports the grounds for the challenge.” See Intelligent Bio-Sys., Inc. v.
