GOOBERMAN Appeal 2020-003073 Application 15/283,751 Technology Center 1600 Before DONALD E. ADAMS, FRANCISCO C. PRATS, and TAWEN CHANG, Administrative Patent Judges. PRATS, Administrative Patent Judge. DECISION ON APPEAL STATEMENT OF THE CASE Pursuant to 35 U.S.C. § 134(a), Appellant1 appeals from the Examiner’s decision to reject claims 22–33. We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM. 1 We use the word Appellant to refer to “applicant” as defined in 37 C.F.R. § 1.42(a). Appellant identifies the real party in interest as Lance L. Gooberman. Appeal Br. 2. Appeal 2020-003073 Application 15/283,751 2 CLAIMED SUBJECT MATTER The claims are directed to methods for blocking and/or reversing the physiological effects of one or more opioids. Claim 22 is representative and reads as follows: 22. A method to block and/or reverse physiological effects of one or more opioids selected from 3-Methylbutyrfentanyl (3- MBF), 3-Methylfentanyl (3-MF), 4-Chloroisobutyrfentanyl (4- CliBF, a.k.a. p-CliBF), 4-Fluorobutyrfentanyl (4-FBF, a.k.a. pFBF), 4-Fluoroisobutyrfentanyl (4-FiBF, a.k.a. p-FiBF), 4- Methoxybutyrfentanyl (4-MeOBF, a.k.a. p-MeO-BF), 4-Fluorofentanyl (4-FF, a.k.a. p-FF), Acetylfentanyl (AF), Acrylfentanyl, AD-1211, AH-7921, α-Methylfentanyl (“China White”), Butyrfentanyl (BF), Desmethylprodine (MPPP), Furanylfentanyl (Fu-F), 4'-Nitromethopholine, Nortilidine, O-Desmethyltramadol, Valerylfentanyl comprising administrating a pharmaceutical formulation in the form of liquid solution for spray administration by the nasal and/or buccal route containing naltrexone in a pharmaceutically efficacious amount as the active ingredient. Appeal Br. 14. REFERENCE(S) The prior art relied upon by the Examiner is: Name Reference Date Fintan Keegan (“Keegan”) US 2017/0071851 A1 Mar. 16, 2017 David Davies et al. (“Davies”) WO 00/62757 A1 Oct. 26, 2000 Appeal 2020-003073 Application 15/283,751 3 REJECTION(S) The following rejections are before us for review: (1) Claims 22–33, under 35 U.S.C. § 112(b) as being indefinite (Ans. 3–4); (2) Claims 22, 24, 26, 27, 28, 30, 32, and 33, under 35 U.S.C. § 102(a)(2) as being anticipated by Keegan (Ans. 4–5); and (3) Claims 22–33, under 35 U.S.C. § 103 as being unpatentable over Keegan and Davies (Ans. 5–7). INDEFINITENESS As an initial matter, we note that while the Examiner restated the rejection for indefiniteness in the Examiner’s Answer, Appellant did not present argument traversing the rejection for indefiniteness in its Appeal Brief. See Appeal Br. 7 (list of appealed rejections does not include rejection for indefiniteness). We note, however, that after the appealed Final Office Action (entered February 26, 2019), the Examiner stated that “[t]he rejection of claims 22-33 under 35 USC 112-2 has been withdrawn after careful consideration.” Advisory Act. 2 (entered April 25, 2019). Accordingly, we find that Appellant’s traversal of the indefiniteness rejection in the Reply Brief is sufficiently timely. Turning to the merits of the indefiniteness rejection, the Examiner determines that “[c]laim 22 recites the limitation ‘efficacious amount’ which is a relative term.” Ans. 3. The Examiner determines, however, that the “efficacious amount would differ from case by case, whether patient is at the chronic stage, weight, age, tolerance capability etc.” Id. at 3–4. Appeal 2020-003073 Application 15/283,751 4 Therefore, the Examiner concludes, “[t]he scope of an efficacious amount is unclear and confusing. Thus, any amount would be encompassed by the unclear scope of the claim.” Ans. 4. We agree with Appellant that the term “efficacious amount” does not render Appellant’s claims indefinite. See Reply Br. 2. A claim does not comply with 35 U.S.C. § 112, second paragraph, “when it contains words or phrases whose meaning is unclear.” In re Packard, 751 F.3d 1310, 1314 (Fed. Cir. 2014) (approving, for pre-issuance claims, the standard from MPEP § 2173.05(e)); see also Ex parte McAward, Appeal 2015-006416, 2017 WL 3669566, at *5 (PTAB Aug. 25, 2017) (precedential) (adopting the approach for assessing indefiniteness approved by the Federal Circuit in Packard). That is, “claims are required to be cast in clear—as opposed to ambiguous, vague, indefinite—terms.” Packard, 751 F.3d at 1313; see also Nautilus, Inc. v. Biosig, Insts., Inc., 572 U.S. 898, 908–10 (2014) (“[A] patent’s claims, viewed in light of the specification and prosecution history, [must] inform those skilled in the art about the scope of the invention with reasonable certainty. The definiteness requirement, so understood, mandates clarity, while recognizing that absolute precision is unattainable.”). In the present case, Appellant’s independent claim 22 recites “[a] method to block and/or reverse physiological effects of one or more opioids selected from” a list of opioids recited in the claim. Appeal Br. 14. Appellant’s claim 28, the other independent claim on appeal, also recites “[a] method to block and/or reverse physiological effects of one or more opioids selected from” a list of opioids recited in the claim. Appeal Br. 15. Appeal 2020-003073 Application 15/283,751 5 Thus, although the appealed independent claims both recite administering the active ingredients in pharmaceutically efficacious amounts, claims 22 and 28 both expressly recite the effect that must result from administering the active agents—blocking and/or reversing the physiological effects of the one or more opioids listed in the claims. We are not persuaded, therefore, that in reciting administration of efficacious amounts, claims 22 and 28 are ambiguous, vague, or unclear. Moreover, the fact that the effect of administering the active agent might vary from case to case does not persuade us that a skilled artisan would be unable to determine, with reasonable certainty, whether a particular administration exhibited an effect encompassed by the claims. Further, while claims 22 and 28 encompass administering any amount of the active agents that block and/or reverse any physiological effects of the listed opioids to any degree, it is well settled that “breadth is not to be equated with indefiniteness.” In re Miller, 441 F.2d 689, 693 (CCPA 1971). In sum, we are not persuaded, for the reasons discussed, that Appellant’s claims are indefinite. We therefore reverse the Examiner’s rejection of claims 22–33 under 35 U.S.C. § 112(b). ANTICIPATION We select Appellant’s claim 22 as representative of the claims rejected by the Examiner as being anticipated by Keegan. See 37 C.F.R. § 41.37(c)(1)(iv) (2018). In rejecting Appellant’s claim 22 as anticipated by Keegan, the Examiner finds that Keegan describes nasally administering naltrexone in amounts encompassed by claim 22 to opioid overdose patients, or suspected Appeal 2020-003073 Application 15/283,751 6 opioid overdose patients, wherein the opioid is one or more of those listed in claim 22. See Ans. 4. Appellant contends, for a number of reasons, that the Examiner erred in finding that Keegan anticipates Appellant’s representative claim 22. See Appeal Br. 10–13; see also Reply Br. 3 (“It is in fact impossible for Keegan to anticipate the claimed inventions.”). Having carefully considered all of the evidence and arguments submitted by Appellant and the Examiner, Appellant does not persuade us that the Examiner erred in determining that Keegan anticipates Appellant’s representative claim 22. Our reviewing court has explained that a reference “need not always include an express discussion of the actual combination [of claimed elements] to anticipate. Instead, a reference may still anticipate if that reference teaches that the disclosed components or functionalities may be combined and one of skill in the art would be able to implement the combination.” Blue Calypso, LLC v. Groupon, Inc., 815 F.3d 1331, 1344 (Fed. Cir. 2016) (citation omitted); see also In re Gleave, 560 F.3d 1331, 1334 (Fed. Cir. 2009) (“As long as the reference discloses all of the claim limitations and enables the subject matter that falls within the scope of the claims at issue, the reference anticipates—no actual creation or reduction to practice is required.”) (internal quotations omitted); Net MoneyIN, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1369 n.5 (Fed. Cir. 2008) (The inquiry is “not constrained to proceed example-by-example when reviewing an allegedly anticipating prior art reference. Rather, the [reviewer] must, while looking at the reference as a whole, conclude whether or not that reference discloses Appeal 2020-003073 Application 15/283,751 7 all elements of the claimed invention arranged as in the claim.”) (emphasis added). In the present case, Keegan discloses “drug products adapted for nasal delivery of an opioid receptor antagonist. Opioid receptor antagonists are a well recognized class of chemical agents. They have been described in detail in the scientific and patent literature.” Keegan ¶ 69. Keegan explains that “[p]ure opioid antagonists, such as naloxone, are agents which specifically reverse the effects of opioid agonists but have no opioid agonist activity.” Id. Keegan discloses that opioid antagonists useful in its nasal formulations are not limited to naloxone, but also include naltrexone, as recited in Appellant’s claim 22: While many of the embodiments of the pharmaceutical compositions described herein will be described and exemplified with naloxone, other opioid antagonists can be adapted for nasal delivery based on the teachings of the specification. In fact, it should be readily apparent to one of ordinary skill in the art from the teachings herein that the devices and pharmaceutical compositions described herein may be suitable for other opioid antagonists. The opioid receptor antagonists described herein include μ-opioid antagonists and δ- opioid receptor antagonists. Examples of useful opioid receptor antagonists include naloxone, naltrexone, methylnaltrexone, and nalmefene. Other useful opioid receptor antagonists are known (see, e.g., Kreek et al., U.S. Pat. No. 4,987,136). Keegan ¶ 73 (emphasis added). Keegan discloses that naltrexone, the active ingredient recited in Appellant’s claim 22, is useful by itself in nasal formulations: Also provided are devices adapted for nasal delivery of a pharmaceutical composition to a patient, comprising a Appeal 2020-003073 Application 15/283,751 8 therapeutically effective amount of an opioid antagonist, wherein the device is pre-primed, and wherein the therapeutically effective amount is about 4 mg to about 12 mg. In some embodiments, the therapeutically effective amount is equivalent to about 3.4 mg of naloxone hydrochloride. In some embodiments, the therapeutically effective amount is equivalent to about 4 mg of naloxone hydrochloride. In some embodiments, the opioid antagonist is selected from naltrexone, methylnaltrexone, and nalmefene, and pharmaceutically acceptable salts thereof. In some embodiments, the opioid antagonist is naltrexone hydrochloride. In some embodiments, the opioid antagonist is methylnaltrexone bromide. In some embodiments, the opioid antagonist is nalmefene hydrochloride. In some embodiments, the opioid antagonist is the only pharmaceutically active compound in pharmaceutical composition. Keegan ¶ 74 (emphasis added). As recited in Appellant’s claim 22, Keegan discloses that its nasal formulations are in liquid form. Keegan ¶ 76. As the Examiner notes (see Ans. 8), Keegan discloses nasally administering naltrexone to treat opioid overdose patients, as recited in Appellant’s claim 22: Also provided are devices, kits, and pharmaceutical formulations for, and methods of, treating opioid overdose or a symptom thereof, reversing the psychotomimetic and dysphoric effects of agonist-antagonists such as pentazocine, diagnosing suspected acute opioid overdosage, treating opioid addiction, or treating septic shock, comprising nasally administering to a patient in need thereof a therapeutically effective amount of an opioid antagonist, wherein the therapeutically effective amount is about 2 mg to about 12 mg. In some embodiments, the therapeutically effective amount is equivalent to about 4.4 mg of naloxone hydrochloride dihydrate. In some embodiments, the therapeutically effective amount is equivalent to about 4 mg of naloxone hydrochloride. In some embodiments, the patient is an opioid overdose patient. In Appeal 2020-003073 Application 15/283,751 9 some embodiments, the patient is not breathing. In some embodiments, the opioid antagonist is the only pharmaceutically active compound in said pharmaceutical composition. In some embodiments, the opioid antagonist is selected from naltrexone, methylnaltrexone, and nalmefene, and pharmaceutically acceptable salts thereof. In some embodiments, the opioid antagonist is naltrexone hydrochloride. Keegan ¶ 469 (emphasis added). Keegan discloses that opioid compounds that cause overdose treatable by its methods include compounds recited in Appellant’s claim 22, such as 3-Methylbutyrfentanyl and 3-Methylfentanyl. Keegan 8 (Table A). Given the above teachings, Appellant does not persuade us that the Examiner erred in determining that, when viewed as a whole, Keegan describes nasally administering a liquid naltrexone formulation to treat overdose caused by 3-Methylbutyrfentanyl and/or 3-Methylfentanyl. Appellant does not persuade us, therefore, that the Examiner erred in determining that Keegan, when viewed as a whole, describes a process having all of the elements of Appellant’s representative claim 22, arranged as in the claim. Indeed, because Keegan must be viewed as a whole, disregarding or ignoring the teachings in paragraphs 73 and 74 of Keegan, as posited by Appellant (see Appeal Br. 11–12), would be erroneous. See Net MoneyIN, 545 F.3d at 1369 n.5 (The inquiry is “not constrained to proceed example- by-example when reviewing an allegedly anticipating prior art reference. Rather, the [reviewer] must, while looking at the reference as a whole, conclude whether or not that reference discloses all elements of the claimed invention arranged as in the claim.”) (emphasis added). Appeal 2020-003073 Application 15/283,751 10 Similarly, because the reference must be viewed as a whole, the fact that Keegan’s working examples might only use naloxone (see Appeal Br. 12) does not demonstrate that Keegan fails to anticipate claim 22. See Net MoneyIN, 545 F.3d at 1369 n.5 (noting that the inquiry is “not constrained to proceed example-by-example”). Indeed, Appellant points to nothing in this Board’s non-precedential decision in Ex parte Zerbe suggesting that it would be proper to ignore the express teachings in Keegan, reproduced above, when evaluating the Examiner’s finding of anticipation. See Appeal Br. 11– 12. Appellant contends that “[t]he courts have long held that a computer generated list of chemical entities without specific teaching of use is not a proper basis for rejection. In re Donohue (II) 766 F.2d 531, 226 USPQ 619 (Fed. Cir. 1985).” Appeal Br. 11. Appellant, however, points to no discussion in Donohue that mentions anything about computer generated lists. See Appeal Br. 11. To the contrary, Donohue expressly states that, for the purposes of anticipation, “[i]t is not . . . necessary that an invention disclosed in a publication shall have actually been made in order to satisfy the enablement requirement.” Donohue, 766 F.2d at 533; accord, Gleave, 560 F.3d at 1334 (“As long as the reference discloses all of the claim limitations and enables the subject matter that falls within the scope of the claims at issue, the reference anticipates—no actual creation or reduction to practice is required.”) (internal quotations omitted). Thus, absent some evidence that the teachings discussed above in Keegan are not enabling, the fact that Keegan’s working examples might not include naltrexone, and the fact that Keegan does not include experimental Appeal 2020-003073 Application 15/283,751 11 evidence of naltrexone’s efficacy, are insufficient to show that Keegan fails to anticipate claim 22. See Appeal Br. 13; Reply Br. 3; see also Gleave, 560 F.3d at 1335 (“[I]n the context of a claimed method for treating a disease, a prior art reference need not disclose proof of efficacy to anticipate the claim.”) (internal quotations omitted). We are not persuaded that Appellant has advanced persuasive evidence suggesting that the disclosures in Keegan describing the nasal administration of naltrexone to treat opioid overdose, reproduced above, are non-enabling. In that regard, we acknowledge Appellant’s citation of Exhibits A2 and B3 to the Appeal Brief. See Appeal Br. 12 (citing Exhibit B); Appeal Br. 13 (citing Exhibit A). Appellant, however, does not point to, nor do we discern, any discussion in either of the exhibits to the Appeal Brief that specifically mentions anything about naltrexone. See Appeal Br. 11–12 (citing Exhibit B); Appeal Br. 13 (citing Exhibit A). Appellant, moreover, does not point to any persuasive evidence suggesting that the alleged difficulties of using naloxone to treat fentanyl overdose, supposedly shown by Exhibits A and B, demonstrates that Keegan’s disclosures regarding naltrexone, an entirely different chemical compound, are non-enabling. We note, in addition, that the articles in Exhibits A and B both have publication dates after the October 3, 2016, filing date of the present application, and Appellant points to no evidence suggesting that the 2 Jessica Firger, Fentanyl Found in Georgia Resists Life-Saving Naloxone Antidote, NEWSWEEK 1–9 (2017). 3 Ronald B. Moss & Dennis J. Carlo, Higher doses of naloxone are needed in the synthetic opioid era, 14 SUBSTANCE ABUSE TREATMENT, PREVENTION, AND POLICY 1–6 (2019) (https://doi.org/10.1186/s13011-019-0195-4). Appeal 2020-003073 Application 15/283,751 12 information disclosed in those articles would have been known or available to skilled artisans at the time the present application was filed. See Exhibit A (2017 publication date); Exhibit B (2019 publication date). Further, while Appellant contends that “many references” have been provided to show that treatment of overdose from fentanyl and/or its analogs is “highly unpredictable” (Reply Br. 3), Appellant does not cite any specific references or evidence other than Exhibits A and B noted above, to support the asserted unpredictability, or inferred lack of enablement, in relation to the disclosures in Keegan. Accordingly, for the reasons discussed, we are not persuaded that Appellant has advanced evidence sufficient to show that the disclosures in Keegan describing the nasal administration of naltrexone to treat opioid overdose, including overdose caused by 3-Methylbutyrfentanyl and/or 3- Methylfentanyl, are non-enabling. Appellant’s arguments alleging teaching away by Keegan are also unpersuasive of non-anticipation by the reference. See Celeritas Techs. Ltd. v. Rockwell Int’l Corp., 150 F.3d 1354, 1361 (Fed. Cir. 1998) (“[T]he question whether a reference ‘teaches away’ from the invention is inapplicable to an anticipation analysis.”) (citation omitted). Appellant argues, in view of OSI Pharmaceuticals, LLC v. Apotex Inc., 939 F.3d 1375, 1383 (Fed. Cir. 2019), that Keegan “does not provide or disclose any data or other information about naltrexone’s ‘efficacy’ in treating fentanyl and fentanyl analog exposure – there is no clinical human data nor even in vitro data.” Reply Br. 3. We are not persuaded. As an initial matter, we are not persuaded that we should consider Appellant’s arguments regarding OSI, because we are not persuaded that those arguments are properly presented for the first time in the Reply Brief. Appeal 2020-003073 Application 15/283,751 13 See 37 C.F.R. § 41.41(b)(2) (“Any argument raised in the reply brief which was not raised in the appeal brief, or is not responsive to an argument raised in the examiner’s answer, including any designated new ground of rejection, will not be considered by the Board for purposes of the present appeal, unless good cause is shown.”); Ex parte Borden, 93 USPQ2d 1473, 1477 (BPAI 2010) (The reply brief is not “an opportunity to make arguments that could have been made in the principal brief on appeal to rebut the Examiner’s rejections, but were not.”) (“Informative”). In any event, the ground of unpatentability involved in OSI was for obviousness, not for anticipation. See OSI, 939 F.3d at 1379. Appellant points to no discussion in OSI suggesting that a reference asserted as being anticipatory must present evidence of efficacy. Directly to the contrary, as noted above, our reviewing court has expressly stated that “in the context of a claimed method for treating a disease, a prior art reference need not disclose proof of efficacy to anticipate the claim.” Gleave, 560 F.3d at 1335 (internal quotations omitted). In sum, for the reasons discussed, Appellant does not persuade us of reversible error in the Examiner’s finding that, when viewed as a whole, Keegan describes nasally administering a liquid naltrexone formulation to treat overdose caused by 3-Methylbutyrfentanyl and/or 3-Methylfentanyl. Appellant does not persuade us, therefore, that the Examiner erred in determining that Keegan, when viewed as a whole, describes a process having all of the elements of Appellant’s representative claim 22, arranged as in the claim. We therefore affirm the Examiner’s rejection of claim 22 as anticipated by Keegan. Because they were not argued separately, claims 24, Appeal 2020-003073 Application 15/283,751 14 26, 27, 28, 30, 32, and 33 fall with claim 22. See 37 C.F.R. § 41.37(c)(1)(iv). OBVIOUSNESS In rejecting claims 22–33 for obviousness over Keegan and Davies, the Examiner relied on the disclosures discussed above in Keegan describing treatment of fentanyl derivative overdoses with naltrexone, and cited Davies as evidence that additional features recited in Appellant’s dependent claims, including dosage amounts and formulation ingredients, would have been obvious variations of the process described in Keegan. See Ans. 5–7. Appellant does not contend that the Examiner erred in determining that a skilled artisan would have combined the cited teachings in Keegan and Davies in the manner posited in the rejection. Rather, Appellant contends that “with the failure of setting out anticipation rejection, therefore, the Examiner has also failed to provide a prima facie case of obviousness against the present U.S. application serial no. 15/283,751.” Appeal Br. 13. We select claim 22 as representative of the claims subject to this ground of rejection. See 37 C.F.R. § 41.37(c)(1)(iv). As discussed above, Appellant does not persuade us that the Examiner erred in determining that Keegan, when viewed as a whole, describes a process having all of the elements of Appellant’s representative claim 22, arranged as in the claim. Accordingly, Appellant does not persuade us that the Examiner erred in determining that the process recited in Appellant’s claim 22 would have been obvious to a skilled artisan, in view of the teachings in Keegan, when combined with Davies. See In re McDaniel, 293 F.3d 1379, 1385 (Fed. Cir. 2002) (“It is well settled that ‘anticipation is the Appeal 2020-003073 Application 15/283,751 15 epitome of obviousness.’”) (quoting Connell v. Sears, Roebuck & Co., 722 F.2d 1542, 1548 (Fed. Cir. 1983)). We therefore affirm the Examiner’s rejection of claim 22 for obviousness over Keegan and Davies. Because they were not argued separately, claims 23–33 fall with claim 22. See 37 C.F.R. § 41.37(c)(1)(iv).
