PRATS, JEFFREYN. FREDMAN, and DEBORAH KATZ, Administrative Patent Judges. FREDMAN, Administrative Patent Judge. DECISION ON APPEAL This is an appeal 1,2,3 under 35 U.S.C. § 134 involving claims to a liquid formulation for the buccal transmucosal administration of an anti- nausea, anti-emetic active ingredient from the setron family. The Examiner rejected the claims as obvious. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. 1 Appellants identify the joint inventors, Philippe Perovitch and Marc Maury, as the real party in interest (see App. Br. 2). 2 We have considered and herein refer to the Specification of June 17, 2011 ("Spec."); Final Office Action of Feb. 5, 2014 ("Final Act."); Appeal Brief of Apr. 22, 2016 ("App. Br."); Examiner's Answer of Nov. 3, 2016 ("Ans."); and Reply Brief of Jan. 3, 2017 ("Reply Br."). 3 An oral hearing was held on October 9, 2018 but Appellants waived transcription due to the unavailability of a court reporter. Appeal2017-003642 Application 13/140,745 Statement of the Case Background "Setrons are pharmaceutical active ingredients used mainly for the prevention or treatment of nausea and vomiting syndromes linked to cancer therapies. These are powerful lipophilic anti-emetic molecules of low molecular weight, which operate at central nervous system level as receptor antagonists" (Spec. 1: 12-17). The "quickest and most effective way to administer setrons is by intravenous transfusion" but to "protect the veins of patients, to facilitate taking the medication, and to reduce costs, it is ... preferable to avoid the intravenous route" (Spec. 1 :34 to 2:7). "The present invention relates to a formulation for instantaneous buccal transmucosal systemic administration of at least one active ingredient belonging to the setron family" (Spec. 1:3---6). The Claims Claims 1, 3, 6, 9, and 19 are on appeal. Claim 1 is representative and reads as follows: 1. A liquid formulation for the buccal transmucosal administration of an anti-nausea, anti-emetic active ingredient from the setron family, wherein the formulation is a solution having a pH in the range 5.0 to 9.0 and combining: · an active ingredient from the setron family in base and/ or salt form; and · a hydroalcoholic solution consisting of water and ethanol, titrating from 40° to 70° alcohol, in which said active ingredient is present in a stable and completely dissolved state, wherein said formulation contains 2 mg to 8 mg of active ingredient in 0.5 to 2 mL of hydroalcoholic solution, 2 Appeal2017-003642 Application 13/140,745 wherein all of the active ingredient passes passively through the buccal mucosa within 6 seconds of administration, and wherein said hydroalcoholic solution is the only solvent of said formulation. The Issues A. The Examiner rejected claims 1, 6, and 9 under 35 U.S.C. § I02(a) as anticipated by Krishnaiah4 (Ans. 2-7). B. The Examiner rejected claims 1, 3, 6, 9, and 19 under 35 U.S.C. § I03(a) as obvious over Heit5 (Ans. 7-11). A. 35 U.S.C. § 102(a) over Krishnaiah The issue with respect to this rejection is: Does the evidence of record support the Examiner's conclusion that Krishnaiah anticipates claim 1? Findings of Fact 1. Krishnaiah teaches "a menthol-based transdermal therapeutic system for ondansetron hydrochloride" (Krishnaiah 228, col. 1 ). 2. Krishnaiah teaches: "Ondansetron hydrochloride is a novel and specific antagonist of 5-HT 3 receptor indicated for the treatment of chemotherapy induced nausea and vomiting in patients with cancer" (Krishnaiah 228, col. 1 ). 4 Krishnaiah et al., Penetration-Enhancing Effect of Ethanolic Solution of Menthol on Transdermal Permeation of Ondansetron Hydrochloride Across Rat Epidermis, 15 DRUG DELIVERY 227-34 (2008). 5 Heit et al., US 2006/0239928 Al, published Oct. 26, 2006. 3 Appeal2017-003642 Application 13/140,745 3. Krishnaiah teaches the "recommended oral dosing regimen of ondansetron hydrochloride for emeogenic neoplastic agents is 8 mg" (Krishnaiah 228, col. 1 ). 4. Table I of Krishnaiah is reproduced below: TABLE.! Coinpositinn of HPC gid drug reservoir containing ondansetron hydrochlorhk and selected concentrnlions of mt::r1thol Ingredients Ondan;,,etron hydrochloride I'vlen!hol HPC Eihanol fo{F.{vlv} q.s.

V L5 10 100 Table I of Krishnaiah teaches a composition, identified as "I", that comprises 1.5 % w/w of the ondansetron hydrochloride salt in a hydroalcoholic solution that is 60% v/v ethanol that contains 2 % w/w HPC (Krishnaiah 228, col. 2). 5. Krishnaiah teaches for preparation of the drug reservoir: Ethanol and water were mixed in different ratios so as to obtain binary solvent systems of 20:80 v/v, 40:60 v/v or 60:40 v/v of ethanol in water. The composition of the drug reservoir (2% w/w HPC gel) containing selected concentrations of menthol was given in Table 1. The HPC powder was added to 60% v/v ethanol-water solvent system while being stirred by means of a stirrer (Mis Remi Motors, India) at 2,500 rpm and the resulting mixture was mixed continuously at 37QC until the gel was formed (1 h). Ondansetron hydrochloride and menthol, in the required quantity, were added to HPC gel and mixed well for 4 Appeal2017-003642 Application 13/140,745 complete dissolution. The drug reservoir formulations were left overnight at room temperature (28 to 30QC). (Krishnaiah 228, col. 2). 6. Krishnaiah teaches for permeation studies that: "Two grams of the drug reservoir formulation or 2 ml of drug solution containing 30 mg of ondansetron hydrochloride, was placed in the donor cell" (Krishnaiah 229, col. 1 ). 7. The Examiner finds Krishnaiah's composition I inherently comprises "a pH in the range of 5.0 to 9.0" (Ans. 4). Principles of Law The Examiner bears the initial burden of establishing a prima facie case of anticipation. In re King, 801 F.2d 1324, 1326-27 (Fed. Cir. 1986). Anticipation under 35 U.S.C. § 102 requires that "'each and every element as set forth in the claim is found, either expressly or inherently described, in a single prior art reference."' In re Robertson, 169 F.3d 743, 745 (Fed. Cir. 1999). Analysis Appellants contend Krishnaiah "require[ s] hydroxypropyl cellulose (HPC) for their transdermal administration of ondansetron"; teaches "a transdermal formulation with a maximum transdermal flux of 77 .85 µg/cm2/hour ... This would require more than 20 hours to administer a dosage of 2 mg"; and "teach a gel for their transdermal formulation" (App. Br. 11, 14, 1 7; emphasis omitted). The Examiner finds Krishnaiah "demonstrates the solubility of ondansetron hydrochloride in various ethanol-water cosolvent systems and ethanol or water alone as shown in Table 2 (see page 230). There is 5 Appeal2017-003642 Application 13/140,745 absolutely no teaching therein which suggests that HPC is included in these formulation[s]" (Ans. 13). The Examiner further contends Krishnaiah "discloses a composition comprising the same ingredients as claimed in the instant application ... and as such any composition disclosed in the prior art comprising the same ingredients as claimed will meet the limitations of the claims even if the intended use is not specifically disclosed in the prior art" (id.). We agree with Appellants. Krishnaiah does not teach a composition that lacks HPC, but rather teaches regarding Table 1 that HPC was added to the ethanol-water solvent system "until a gel was formed" and only then was the ondansetron "added to the HPC gel" (FF 5). Krishnaiah also teaches that the permeation studies shown in Figure 1 used "[t]wo grams of the drug reservoir formulation or 2 ml of drug solution containing 30 mg of ondansetron hydrochloride" (FF 6). As already noted, the reservoir solution contains HPC (FF 5) and there is no indication that the drug solution was a different composition than the drug reservoir formulation. Even if we agreed with the Examiner that the composition used in Figure 1 lacked HPC and was in liquid form, Figure 1 shows a drug flux that required hours for delivery of the ondansetron, a time frame excluded by the limitation in claim 1 requiring that "wherein all of the active ingredient passes passively through the buccal mucosa within 6 seconds of administration." We are not persuaded by the Examiner's inherency argument because "[i]nherency ... may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is 6 Appeal2017-003642 Application 13/140,745 not sufficient." MEHL/Biophile Int'!. Corp. v. Milgraum, 192 F.3d 1362, 1365 (Fed. Cir. 1999). In this case, the Examiner has not established that a solution identical to that recited by claim 1 was created by Krishnaiah which had the same amount of active setron agent in the hydroalcoholic solution, the same pH, in liquid form. Conclusion of Law The evidence of record does not support the Examiner's conclusion that Krishnaiah anticipates claim 1. B. 35 U.S.C. § 103(a) over Heit The issue with respect to this rejection is: Does the evidence of record support the Examiner's conclusion that Heit renders claim 1 obvious? Findings of Fact 8. Heit teaches "transmucosally administering a prophylactically or therapeutically effective amount of one or more active agents to an animal in need thereof. Preferred administering means include, but are not limited to, sprays or mists of the one or more active agents into the oral cavity of the animal" (Heit ,r 2). 9. Heit teaches a spray composition "(i.e., propellant free composition), for transmucosal administration of a pharmacologically active agent soluble in a pharmacologically acceptable polar solvent comprises in weight % of total composition: aqueous polar solvent from about 30 to about 99.69%, active agent from about 0.001 to about 60%" (Heit ,r 186). 10. Heit teaches a "preferred polar solvent is aqueous ethanol" (Heit ,I 128). 7 Appeal2017-003642 Application 13/140,745 11. Heit teaches: "Non-limiting examples of suitable anti-emetic agents include ... 5HT -3 receptor antagonists such as ondansetron, granisetron, tropisetron, dolasetron, hydrodolasetron, azasetron, ramosetron, lerisetron, indisetron and palonosetron" (Heit ,r 141 ). 12. Heit teaches assays may optionally be employed to help identify optimal dosage ranges. The precise dose to be employed in the compositions may also depend on the route of administration and the seriousness of the disease, disorder, or condition and on the animal being treated, and should be decided according to the judgment of the practitioner and each animal's particular circumstances. (Heit ,I 169). 13. Heit teaches: "Suitable dosage ranges for transmucosal administration to the oral mucosa are generally from about 0.001 milligram to about 200 milligrams of a non-steroidal anti-inflammatory agent of the invention per kilogram body weight" (Heit ,r 191 ). 14. Heit teaches: "To administer a transmucosal oral mist, the commissure of the animal's ... lips will be grasped ... opening the buccal space. The mist is typically directed caudally and towards the gingival and/or buccal mucosal surfaces" (Heit ,r 174). 15. Heit teaches that: "If the dose is greater than about 3 00 to about 500 micro liters, the dose may be split between both sides of the mouth" (Heit,I 174). 16. Heit teaches the "compositions, if desired, can also contain minor amounts of ... pH buffering agents" (Heit ,r 127). 17. Heit teaches the transmucosal methods provide a "shorter time frame needed to achieve maximum plasma concentration and greater 8 Appeal2017-003642 Application 13/140,745 bioavailability may be provided by the compositions and methods of the invention" (Heit ,r 63). 18. Heit teaches: "Transmucosal administration of the active agent compositions of the invention preferably exhibits increased bioavailability, requires smaller doses, and exhibits shorter time to reach maximum plasma concentration after administration" (Heit ,r 153; emphasis added). Principles of Law "The combination of familiar elements according to known methods is likely to be obvious when it does no more than yield predictable results." KSR Int'! Co. v. Teleflex Inc., 550 U.S. 398,416 (2007). Analysis We adopt the Examiner's findings of fact and reasoning regarding the scope and content of the prior art (Ans. 7-11; FF 8-18) and agree that the claims are obvious over Heit. We address Appellants arguments below. Appellants contend "Heit et al. contains extremely generic paragraphs filled with laundry lists of possible components. Further, Heit et al. provide no particular guidance for how to prepare a suitable transmucosal formulation for any of the disparate active ingredients, except for the few examples set forth in the reference" (App. Br. 22). Appellants contend (Id.). Heit et al. do not even disclose any examples that employed an active ingredient from the setron family. Heit et al. 's failure to provide specific guidance regarding the preparation of a formulation for setrons is particularly significant given that using this route for delivering an active ingredient in the setron family was not obvious. We do not find the "laundry list" argument persuasive. Simply because Heit "discloses a multitude of effective combinations does not 9 Appeal2017-003642 Application 13/140,745 render any particular formulation less obvious." Merck & Co. v. Biocraft Labs., Inc., 874 F.2d 804, 807 (Fed. Cir. 1989). In Corkill, an obviousness rejection was affirmed in light of prior art teachings that "hydrated zeolites will work" in detergent formulations, even though "the inventors selected the zeolites of the claims from among 'thousands' of compounds." In re Corkill, 771 F.2d 1496, 1500 (Fed. Cir. 1985). Here, Heit teaches buccal transmucosal administration of drugs (FF 8, 9, 14) including a variety of setron family drugs (FF 11) in a hydroalcoholic solution with ethanol as the preferred solvent (FF 9, 10) in overlapping dosages of drug (FF 13), overlapping volumes of administration to the buccal mucosa (FF 15) in a pH buffered solution (FF 16). Such "picking and choosing may be entirely proper in the making of a 103, obviousness rejection." In re Arkley, 455 F.2d 586, 587 (CCPA 1972). We also agree with the Examiner that an ordinary "artisan would be able to clearly envisage Applicant's claimed compound from the list of preferred active agents since the genus is limited, thus very few combinations can be obtained (see abstract and claim 6)" (Ans. 17). Appellants contend "there are no examples in Heit et al. that employed a setron. Further, there is no disclosure in Heit et al. that provides some form of teaching regarding a suitable composition for delivering a setron via transmucosal administration" (App. Br. 23). Appellants also contend "none of the examples of Heit et al. employed a hydroalcoholic solution consisting of water and ethanol, titrating from 40° to 70° alcohol, wherein the hydroalcoholic solution was the only solvent in the formulation" (App. Br. 24). 10 Appeal2017-003642 Application 13/140,745 We find this argument unpersuasive because "a reference is not limited to the disclosure of specific working examples." In re Mills, 470 F .2d 649, 651 (CCP A 1972). Heit teaches and claims ondansetron compositions for buccal administration (FF 8, 11; see Heit 29, claims 1, 4, 6). Heit further teaches overlapping ranges of alcohol concentrations (FF 9). In cases involving overlapping ranges, we and our predecessor court have consistently held that even a slight overlap in range establishes a prima facie case of obviousness ... The normal desire of scientists or artisans to improve upon what is already generally known provides the motivation to determine where in a disclosed set of percentage ranges is the optimum combination of percentages. In re Peterson, 315 F.3d 1325, 1329, 1330 (Fed. Cir. 2003). Heit provides a reason to optimize the composition and expressly teaches to "identify optimal dosage ranges" (FF 12). Heit provides reasons to optimize for rapid delivery, teaching that a "shorter time frame needed to achieve maximum plasma concentration and greater bioavailability may be provided by the compositions and methods of the invention" (FF 17, cf FF 18). Appellants contend claim 1 further requires that all of the 2 to 8 mg of the setron must pass through the buccal mucosa within 6 seconds. Heit al. cannot inherently disclose this element of the claims for a number of reasons. For example, Heit et al. do not specifically address this type of rapid delivery of the active ingredient. Instead, Heit et al. repeatedly refers to "minutes," and never refers to administration within seconds. This is most likely, among other reasons, because Heit et al. are directed to formulations to be delivered by spraying. Appellants addressed the drawbacks with this type of approach. (App. Br. 25). 11 Appeal2017-003642 Application 13/140,745 We find this argument unpersuasive for two reasons. First, we agree with the Examiner that Heit "teaches the same transmucosal administration of active ingredients including ondansetron, and thus an ordinary skilled artisan would necessarily arrive at the exact amounts of ondansetron and aqueous ethanol as claimed in the instant application since the intended purpose of providing a composition by transmucosal administration is the same" (Ans. 20). That is, the optimized liquid ondasetron formulation in a hydroalcoholic solution for buccal administration rendered obvious by Heit (FF 9-17) would have reasonably shared the inherent property of passive administration within six seconds as required by claim 1. As noted in Best, Where, as here, the claimed and prior art products are identical or substantially identical ... the PTO can require an applicant to prove that the prior art products do not necessarily or inherently possess the characteristics of his claimed product. .. . Whether the rejection is based on 'inherency' under 35 U.S.C. § 102, on 'prima facie obviousness' under 35 U.S.C. § 103, jointly or alternatively, the burden of proof is the same, and its fairness is evidenced by the PTO' s inability to manufacture products or to obtain and compare prior art products. In re Best, 562 F.2d 1252, 1255 (CCPA 1977). Appellants provide no evidence that any of the liquid formulations of Heit, administered by the buccal transmucosal route directly as preferred by the Specification (compare Spec. 4:20-15 to 5:9-14), rather than as a spray or oral mist as taught by Heit (see Heit ,r,r 266, 270, 278, etc.), would not satisfy the 6 second functional requirement of claim 1. Second, while we agree that the recitation "wherein all of the active ingredient passes passively through the buccal mucosa within 6 seconds of administration" limits claim 1, the limitation relies upon a particular intended administration mode. That is, claim 1 is a product claim and the 6 12 Appeal2017-003642 Application 13/140,745 second limitation represents an intended delivery mode for the liquid formulation. The 6 second limitation does not impose any particular structural limitation on the liquid formulation itself. A "mere statement of a new use for an otherwise old or obvious composition cannot render a claim to the composition patentable." In re Zierden, 411 F.2d 1325, 1328 (CCPA 1969). Appellants rely upon the Maury Declaration, 6 which states "the claimed formulation is not a simple matter of optimization" (Maury Deel. ,r 17). Appellants contend the Maury "Declaration explained that the claimed rapid absorption-within 6 seconds-of all of the active ingredient is only possible with the specific claimed formulation" (App. Br. 26). Appellants contend the claimed formulation is not a simple matter of optimization, but instead provides a very specific combination of features to obtain a huge benefit to the patient. Furthermore, Heit et al. do not provide a person of ordinary skill in the art with any information to obtain or arrive at the claimed formulation having the claimed rate of administration. (App. Br. 27). We find these arguments and Declaration unconvincing because there is no persuasive evidence rebutting the express statement of Heit that dosages may be optimized (FF 12) and teachings of overlapping ranges of the components (FF 9-16). Claim 1 broadly encompasses a wide range of 6 Declaration of Dr. Marc Maury, dated June 27, 2014. 13 Appeal2017-003642 Application 13/140,745 hydroalcoholic solutions from 40Q to 70Q alcohol7 that significantly overlaps the 30 to about 99.69% range for alcohols disclosed by Heit (FF 9). "In fact, when, as here, the claimed ranges are completely encompassed by the prior art, the conclusion is even more compelling than in cases of mere overlap." Peterson, 315 F.3d at 1330. We have considered Dr. Maury's statements along with the express teachings of Heit, but find them unpersuasive because no criticality or unexpected results are demonstrated for the somewhat smaller range of ethanol concentrations. See In re American Academy of Science Tech Center, 367 F.3d 1359, 1370 (Fed. Cir. 2004) ("[T]he Board is entitled to give such weight to declarations as it deems appropriate.") Indeed, when Appellants contend that the examples of Heit were "either below or above the claimed range of 40° to 70°", Appellants fail to take the next step and provide experimental evidence showing that these compositions would not have inherently resulted in rapid absorption within 6 seconds when administered as directed by the Specification. While Heit's use of different administration modes, either oral or spray, fail to achieve this absorption, claim 1 is a product claim, not a method claim. To the extent that the 6 second limitation imposes a particular administration mode, Appellants provide no evidence that Heit's compositions, when so administered, would not satisfy the rapid absorption requirement. Appellants contend that "absent any guidance in Heit et al., it would have required lengthy and costly experimentation to obtain efficient formulations. This is clearly undue and unreasonable experimentation, 7 The Reply Brief notes that "40° ethanol is equal to 33.4% ethanol and that titrating 70° ethanol is equal to 62.5% ethanol" (Reply Br. 6-7). 14 Appeal2017-003642 Application 13/140,745 which demonstrates that Heit et al. do not suggest or enable the claimed formulation" (App. Br. 29; cf App. Br. 28). We are not persuaded because attorney argument is not evidence, even calculations that "formulation experiments for all said 46 active ingredients would require 7 x 46 = 322 months-27 years" (App. Br. 28). Moreover, Appellants do not establish, with evidence, any of the underlying presumptions of this calculation (see App. Br. 28). See In re Pearson, 494 F.2d 1399, 1405 (CCPA 1974) ("Attorney's argument in a brief cannot take the place of evidence."). See also In re De Blauwe, 736 F.2d 699, 705 (Fed. Cir. 1984) (Arguments and conclusions unsupported by factual evidence carry no evidentiary weight.) Nor do Appellants provide evidence to establish that the ordinary artisan, using Heit's guidance as a roadmap, would have required undue experimentation based on the Wands factors. See In re Wands, 858 F.2d 731, 737 (Fed. Cir. 1988). There is no evidence of unpredictability in this highly skilled art with detailed guidance provided by Heit (FF 9-17). See Wyeth & Cordis Corp. v. Abbott Labs., 720 F.3d 1380, 1386 (Fed. Cir. 2013) ("a considerable amount of experimentation is permissible," as long as it is "merely routine" or the disclosure "'provides a reasonable amount of guidance' regarding the direction of experimentation" (quoting Johns Hopkins Univ. v. CellPro, Inc., 152 F.3d 1342, 1360-61 (Fed. Cir. 1998)). Here, Heit provides guidance regarding selection of the amount and type of active agent, the amount and type of solvent, and specifically teaches liquid formulations for buccal transmucosal administration that may include setrons in ethanol based hydroalcoholic solutions (FF 9-17). 15 Appeal2017-003642 Application 13/140,745 Appellants also contend a "person of ordinary skill in the art would appreciate that a sprayable formulation, as is disclosed by Heit et al., will be mainly swallowed. This makes it impossible to have all of the active ingredient pass through the mucosa. Accordingly, no evidence is needed to confirm Appellants' assertion" (Reply Br. 7-8). We find this argument unpersuasive for two reasons. First, mere assertions are not evidence. De Blauwe, 736 F.2d at 705. Second, this argument imposes a requirement not present in claim 1, the mode of administration of the formulation, because claim 1 is limited to the product, not the method of administration. The issue is not whether Heit, when administered as a spray, satisfies the requirements of the claim, but rather whether the composition of Heit when administered as a liquid to the buccal mucosal surfaces, necessarily has complete passage of active agent "through the buccal mucosa within 6 seconds" as required by claim 1. The Examiner has reasonably shifted the burden, under Best, to Appellants to demonstrate that Heit would not inherently satisfy this requirement when administered in the same way as Appellants, and Appellants have provide no such evidence. Conclusion of Law The evidence of record supports the Examiner's conclusion that Heit renders claim 1 obvious. SUMMARY In summary, we reverse the rejection of claims 1, 6, and 9 under 35 U.S.C. § 102(a) as anticipated by Krishnaiah. We affirm the rejection of claim 1 under 35 U.S.C. § 103(a) as obvious over Heit. Claims 3, 6, 9, and 19 fall with claim 1. 16 Appeal2017-003642 Application 13/140,745 No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a).
