In summary, given that it not accompanied by supporting evidence, does not provide any technical reasoning, and is not specific to Klimesch, we give little weight to Dr. Silvetz’s testimony in determining whether Petitioner has established a reasonable likelihood that Klimesch inherently discloses the intrinsic frequency limitation.

See, e.g., Ex. 1002, 204–208. When Patent Owner responded to the Examiner by highlighting data (i.e., Figure 8 of the specification giving rise to the ’029 patent) showing a notable increase in cognitive function in patients with two ApoE4 alleles (homozygous) who were administered tramiprosate as compared to the ApoE4 “all-comers” (mixed homozygous/heterozygous population), the Examiner suggested narrowing the pending claims to treatment of ApoE4 homozygotes. Ex. 1002, 342. Patent Owner submitted amended claims requiring selection of patients for treatment who were homozygous for ApoE4, and argued: The presently amended claims . . . select only ApoE4 homozygotes for treatment with tramiprosate or a prodrug thereof, necessarily omitting ApoE4 heterozygotes from such treatment. . . . Caltagirone fails to teach or suggest a patient selection strategy that would limit tramiprosate treatment to patients having two ApoE4 alleles and, in fact, teaches away from such selection. Kong fails to contradict or overcome these deficiencies in Caltagirone. Kong does not refer to any patient selection strategy, much less one that would limit tramiprosate prodrug treatment to ApoE4 homozygotes. The Office's reliance on Kong is solely for its teaching of a tramiprosate prodrug. Thus, the combination of Caltagirone and Kong, taken under the Office’s interpretation, suggests treatment of all ApoE4+ patients with a prodrug of tramiprosate. This falls far short of suggesting the presently claimed patient selection and treatment strategy which selects only ApoE4 homozygotes for treatment and does not treat ApoE4 heterozygotes.

    “Babic ascertained that “different effects of a drug could be observed in different subpopulations of patients based on ApoE4 carrier status”” and that “drug effects in homozygous carriers could be greater than those in the heterozygous carriers and non-carriers who did not respond to the drug.” Ex. 1003 ¶ 107. As stated, this testimony does not support Petitioner’s contention that an ordinary artisan would have been motivated “to select homozygous ApoE4 carriers for treatment with any drug for which response has been correlated to ApoE4 carrier status.” See Pet. 41 (emphasis added). In particular, we find an insufficient factual basis for Petitioner’s contention that results obtained for galantamine, an acetylcholinesterase inhibitor (Ex. 1003 ¶ 105) would have motivated an ordinary artisan to replace the galantamine taught in Babic with tramiprosate (homotaurine), a GABA receptor agonist that works by a different mechanism (Ex. 1007, 582). We have also considered Dr. Ruffalo’s testimony that the ordinary artisan would have been motivated to replace Babic’s galantamine with tramiprosate as taught in Caltagirone or Val-APS as taught in Kong. Ex. 1003 ¶¶ 276–277. Dr. Ruffalo posits that Babic’s disclosures would have motivated the ordinary artisan to analyze Caltagirone’s data to ascertain if tramiprosate is more effective in homozygotes, and to replace galantamine with tramiprosate or Val-APS as taught in Kong because of their improved safety profiles as compared to galantamine, and because the replacement drugs target the underlying disease and not symptom amelioration as does galantamine. Id. Dr. Ruffalo also posits that the prior art would have imparted the following knowledge to the ordinary artisan: because the effect of tramiprosate was dependent on the required ApoE4 allele, homozygotes having the highest number of ApoE4 allele copies would derive, at the very least, as much benefit as from the drug as the heterozygotes having only one copy of the allele, and most likely the homozygotes would have the greatest therapeutic response to tramiprosate since they have the maximum number of copies of the required allele. Having done this simple assessment, A POSA would conclude that tramiprosate would be expected to exhibit a greater therapeutic effect in homozygotes and thus would have been motivated to treat homozygotes with tramiprosate, including in an oral dosage form as taught by Aisen. Id. Dr. Ruffalo further posits that the skilled artisan would have had a reasonable expectation of success in administering tramiprosate to treat homozygous ApoE4 patients because they “would almost certainly have the greatest response to the drug.” Id. ¶ 286. Patent Owner argues that the Examiner previously examined the issue of whether ApoE4 genotypes in treatment decisions should be considered during prosecution, with respect to Caltagirone, where ApoE4 genotypes were included, and Sleegers (Ex. 1002, 685, 1137), where studies led away from such inclusion.

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

    “To interpret “stable,” we begin with how the term is used in independent claims 7 and 19. Both terms recite “stable” in relation to the pharmaceutical formulation as a whole by reciting “wherein the formulation is stable.” Ex. 1001, 189:62–190:27. From this, we conclude that the ordinary artisan, as defined above to have a relevant advanced degree and at least two years of experience in development or manufacture of therapeutic protein formulations, would have understood that the components of a “stable” formulation would maintain their integrity and desired function following preparation, including when stored as described. This meaning is supported by the following language in the specification pertaining to the disclosed pharmaceutical compositions: Pharmaceutical compositions according to the present invention are described in further details hereinbelow. In one aspect, the pharmaceutical compositions disclosed herein are physico-chemically stable and maintain the integrity of an antibody comprised in said pharmaceutical composition, for example when stored for 8 weeks at 40° C. as shown hereinbelow. Ex. 1001, 84:20–26. We also note, as Petitioner argued, that the prosecution history supports that the formulation components needed to remain functional during storage, and that Patent Owner cited to formulation integrity after a storage period of 8 weeks at 40° C as evidence of such integrity. Ex. 1004, 7380. As disclosed in the ’265 patent, Examples 9 and 12 measure function and identity of the components following storage to confirm formulation stability.” slip op. at 11

    “burden of showing that claim 7 or 14 lacks written description support in the priority application, which Petitioner has conceded provides the same support as the ’265 patent specification. In this regard, we agree that the reasoning in Fresenius likewise applies: there is no legal requirement that a patent specification must include test results or working examples demonstrating stability for every possible composition that is covered by the claims. Fresenius at 13, citing Ariad Pharms., 598 F.3d at 1352 (stating that “the written description requirement does not demand either examples or an actual reduction to practice”). Formulations 2 and 3, disclosed in the ’265 patent specification, which Petitioner acknowledges falls within the scope of claims 7 and 14 (Pet. 26–27 (citing Ex. 1002 ¶¶ 134, 135)), were shown to be stable for 8 weeks in a syringe. Moreover, the ordinary artisan was provided with guidance in making such formulations from the teachings of the specification and has additional knowledge from the art. See Ex. 1001, 85:32–94:35. Claims 7 and 14 identify specific structures (risankizumab) and required excipients within a defined pH range, which are stable as confirmed by testing results presented in the specification. Prelim. Resp. 33; Ex. 1001, 94:14–36. On this record, we conclude that the evidence presented does not establish that it is more likely than not that an ordinarily skilled artisan would not have reasonably believed that the inventors of the ’265 patent possessed the claimed subject matter, each limitation of which is demonstrated as supported in the specification. As we have interpreted the claim term “wherein the formulation is stable” to mean “wherein the formulation maintains the functional integrity of the antibody and other components, for example when stored for 8 weeks at 40° C,” the specification supports maintenance of functional integrity as shown by the stability of Formulations 2 and 3, including when stored for a period of time.

    “We acknowledge that in the Fresenius case, the extensive testing disclosed in that specification supported the ordinary artisan’s ability to formulate stable compounds using such guidance, and that the specification here discloses less testing. See, e.g., Sur-Reply. 8–9. Nevertheless, it is Petitioner’s burden on this issue, and we are not persuaded that the concerns raised by Dr. Klibanov provide sufficient evidence of actual instability to justify institution on this record. See, e.g., Atlas Powder Co. v. E.I. du Pont De Nemours & Co., 750 F.2d 1569, 1577 (Fed. Cir. 1984) (finding lack of evidence that district court erred in upholding claims as enabled where defendant did not identify inoperable embodiments despite extensive testing). In particular, we are persuaded that, on this record, Petitioner’s lack of evidence of instability of any formulation falling within the limitations of claim 14 indicates that Petitioner has not established sufficiently, for purposes of trial institution, that it is more likely than not that an ordinarily skilled artisan would not have been able to practice the full scope of claim 14 invention based on the teachings of the specification.” slip op. at 28

    “definition focuses on chemistry and materials science without a specific focus to the application of that knowledge to the subject matter of the invention, while Patent Owner’s proposal permits the artisan’s degree to be in horticulture or plant science, requires at least 2–4 years of experience in the area of postharvest biology and technology, and specifically requires “working with encapsulated gaseous agents such as the 1-MCP encapsulation complex.” PO Resp. 14. It is not clear on the record before us nor does Patent Owner’s expert explain why the additional, specific expertise in postharvest biology and technology would have been required to understand the teachings of the ’185 patent in a manner necessary to apply them. Moreover, the proposed additional skill level does not appear to be necessary in light of the skill level reflected by the asserted prior art. See 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. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163–64 (Fed. Cir. 1985)). For instance, Hisano measures preservation visually, by ascertaining whether the flowers looked fresh or appeared to have been harmed by effects of the chemicals added, and whether the water the flowers were stored in was cloudy. Ex. 1004 ¶ 24. This observation does not require specific expertise in postharvest biology and technology. Petitioner’s assessment appears consistent with the level of ordinary skill in the art at the time of the invention as reflected in the prior art in this proceeding, although we agree with Patent Owner that a degree in plant physiology, horticulture, plant science or the like along with work experience, or a master’s degree in exchange for such work experience, in the area of controlled release of compounds would provide sufficient expertise to understand the teachings of the ’185 patent in a manner necessary to apply them.

  • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundUnpatentable

    “We find that the ordinarily skilled artisan would have looked at Hisano as an analogous reference and would have been motivated to try scaling up its smaller-scale solution of effervescent tablets for delivery on a larger scale than single flower vases. We further find that the artisan would not have been deterred by Hisano’s lack of embodiments including gas agents and disclosing local use only that would have prevented use of 1- MCP directly with plants. Ex. 2013 ¶¶ 52–54. In particular, because Daly suggested the molecularly encapsulated 1-MCP could be made in powder form (Ex. 1005, 11:1–11), which is the form Petitioner suggested for use in the proposed obviousness combination (e.g., Pet 36–37), we are not persuaded by Patent Owner’s arguments regarding concerns the skilled artisan would have had about working with 1-MCP gas that is released into the atmosphere where the atmosphere becomes the treatment medium as opposed to a liquid medium. agent, along with Daly’s teachings that 1-MCP is a known substitute for STS without STS’s toxic waste byproduct would have motivated the artisan to explore use of 1-MCP. Daly’s teaching of using a cyclodextrin cage-stabilized and powdered version of 1-MCP to inhibit ethylene binding in plants would have motivated the skilled artisan to try this stabilized version in Hisano’s effervescent tablet preparation because of the benefits of effervescent ingredients for dissolution and dispersion, to treat plants on a larger scale. See Ex. 1005 11:1–20; Ex. 1006 ¶¶ 29, 110–115; Ex. 1035 ¶¶ 11–18. Hisano instructs the artisan about optimization by creating tablets with a proper “effervescence component: freshness preserving component to a weight ratio of between 6.5:3.5 and 5.0:5.0 to create a large, compact tablet agent that can secure some degree of the freshness preserving component” while also stabilizing the tablet for transportation and adjusting the ratios of components to affect the “target quality, effervescence effects, and dissolution time, etc. of the final product.” Ex. 1004 ¶¶ 12, 14. These additional teachings would have led the skilled artisan to understand that an effervescent tablet dosage made with cyclodextrin-stabilized 1-MCP could be made for larger scale production and use. In particular, we find that the artisan would have been motivated to combine the teachings of Hisano and Daly because of 1) Daly’s teaching that STS is problematic for use in inhibiting ethylene in plants due to difficulties in silver waste byproduct disposal, leading to “a great desire among postharvest physiologists to find alternatives to STS” (Ex. 1005, 2:42–64); 2) Daly’s teachings that cyclopropene and its derivatives, including 1-MCP, are “commercially acceptable replacement[s] for STS”) (id. at 1005) and that powder complexes provided advantages over 3) Hisano’s teaching that an ethylene suppressing agent could be delivered via an effervescent tablet, which when dissolved in water, creates “generated carbonic acid gas [that] will promote assimilation action, which will be effective for cultivating, and preserving the freshness of, the cut flowers (plants).” Ex. 1004 ¶ 25; see also Ex. 1006 ¶¶ 113–115 (opining that the skilled artisan would have understood encapsulated 1-MCP, a powder-based form, to be one of a finite number of safer substitutes for STS that could be incorporated into an effervescent tablet using methods known to the skilled artisan at the time); Ex. 1013 at 9 (identifying 1-MCP as a newly discovered “ethylene inhibitor [that acts] as a binding site competitor and is very promising as a postharvest treatment for both potted plants and fresh cut flowers [giving] ethylene protection equal to that obtained from STS, but without silver” and noting that a “company plans to sell the product in a powder form that will release MCP gas when mixed with water”). The art suggested finding substitutes for STS, meaning that the skilled artisan would have looked for likely substitutes such as this stable form of 1-MCP for use in various delivery methods. See, e.g., In re Kerkhoven, 626 F.2d 846, 850 (“It is prima facie obvious to combine two compositions each of which is taught by the prior art to be useful for the same purpose, in order to form a third composition which is to be used for the very same purpose.”).” slip op. at 25

  • PTAB / AIA Trials › Institution threshold (reasonable likelihood / more likely than not)Institution denied meritsInstitution denied

    “Determining whether a patent is subject to the first-inventor-to-file provisions of the AIA, and therefore eligible for post-grant review, is straightforward when the patentee filed the application from which the patent issued before March 16, 2013, or when the patentee filed the application on or after March 16, 2013, without any priority claim. The determination is more complex, however, for a patent that issues from a “transition application,” that is, an application filed on or after March 16, 2013, that claims the benefit of an earlier filing date. See MPEP § 2159.04 (9th ed. Rev. 10.2019, June 2020). Entitlement to the benefit of an earlier date under 35 U.S.C. §§ 119, 120, 121, or 365 is premised on disclosure of the claimed invention “in the manner provided by § 112(a) (other than the requirement to disclose the best mode)” in the earlier application. See 35 U.S.C. §§ 119(e), 120. Thus, a patent that issues from a transition application is not available for post-grant review if the claimed subject matter complies with the written description and enablement requirements of § 112(a) for an ancestor application filed prior to March 16, 2013.” slip op. at 9

    “Patent Owner proposes the same definition as Petitioner, but adds that the skilled artisan “would also have had experience in JAK inhibition, deuteration, and AA [alopecia areata] formulations, or access to a person with that knowledge and experience.” Resp. 15 (citing Ex. 2059 ¶ 14). Patent Owner’s expert Dr. Ko critiques Petitioner’s proposed definition as “incomplete, because it lacks any requirement for experience, or access to individuals with experience, in JAK inhibition, deuteration, and AA formulations.” Ex. 2059 ¶ 16. However, neither Dr. Ko nor Patent Owner explains what difference this additional direct experience would have provided to an artisan with the skill level proposed by Petitioner, particularly when Petitioner’s definition includes “experience in treating hair loss disorders,” and for which the record contains evidence that existing JAK inhibitors such as ruxolitinib had been identified as causing reversal of hair loss caused by AA.

    “embodiments that operate with a low frequency driving signal in a double-ended configuration, Patent Owner did not recite “low frequency” or “double-ended” in its claims and instead chose the broader term “first driving mode.” See In re Am. Acad. of Sci. Tech Ctr., 367 F.3d 1359, 1369 (Fed. Cir. 2004) (“We have cautioned against reading limitations into a claim from the preferred embodiment described in the specification, even if it is the only embodiment described, absent clear disclaimer in the specification.”). The fact that a limitation in the specification may define over the prior art does not justify importing that limitation into the claims unless a term is expressly defined such that the patentee becomes his own lexicographer or there is an express disavowal of claim scope. See GE Lighting Sols., LLC v. AgiLight, Inc., 750 F.3d 1304, 1308–09 (Fed. Cir. 2014). There is no evidence of an express disavowal here. As to lexicography, we disagree with Patent Owner’s contention that the Specification defines the phrase “first driving mode.” Patent Owner relies on the mere fact that the specification describes an embodiment with a first driving mode that has a low frequency driving signal and is in a “double-ended” configuration, but this is not sufficient to define the term. The specification does not require that a low frequency driving signal must necessarily be used. In fact the specification, although not entirely clear, suggests that the driving signal may be from a high frequency ballast. Ex. 1001, 51:8–14. Thus, the fact that the patent here discloses a low frequency driving signal does not mean that all the claims are directed to such a driving signal. See E-Pass Tech., Inc. v. 3Com Corp., 343 F.3d 1364, 1368–69 (Fed. Cir. 2003). Indeed, dependent claim 15 recites “the first driving mode is performed when the external driving signal is a relatively low frequency or voltage signal,” while the independent claims were directed to a more general driving signal. The doctrine of claim differentiation suggests that the independent claims here should not include explicit limitations of a dependent claim. See Phillips, 415 F.3d at 1315 (“[T]he presence of a dependent claim that adds a particular limitation gives rise to a presumption that the limitation in question is not present in the independent claim.”); Liebel-Flarsheim Co. v.
