FLAX, Administrative Patent Judges. SMITH, Administrative Patent Judge. DECISION ON APPEAL This is an appeal under 35U.S.C. § 134 involving claims to a method of treating tissue damage resulting from exposure to lethal amounts of radiation. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. 1 According to Appellants, the real party in interest is Soligenix, Inc. (Appeal Br. 3.) Appeal 2016-001026 Application 12/633,631 STATEMENT OF THE CASE Claims on Appeal Claims 1,4, 5, 10, 13, and 15—17 are on appeal. (Corrected Claims App., dated April 20, 2015.) Claims 1 and 5 are illustrative and read as follows (emphases added): 1. A method of treating the severity of cellular and tissue damage due to increased rate of epithelial apoptosis in a subject resulting from exposure to lethal amounts of radiation consisting of administering to the subject an effective amount of topically active corticosteroid beclomethasone dipropionate in an oral formulation that releases beclomethasone dipropionate locally in the small bowel sufficient to expose a metabolite thereof selected from the group consisting of beclomethasone-17-monopropionate and 21-beclomethasone monopropionate to damaged epithelial cells such that epithelial apoptosis is disrupted. 5. A method for using a pharmaceutical composition for ameliorating or treating damage to the lining of the alimentary tract of a patient wherein the damage is a result of the patient’s exposure to lethal amounts of radiation consisting of: a. ) administering an effective amount of topically active corticosteroid beclomethasone dipropionate or metabolite thereof selected from the group consisting of beclomethasone- 17-monopropionate and 21-beclomethasone monopropionate in oral dosage form wherein the effective amount is 8 mg/day; and b. ) administering a second compound that is intended to treat another cellular aspect of tissue damage, wherein the second compound is selected from the group consisting of growth factors, regulator molecules, keratinocyte growth factor (KGF), R-spondin-1, R-spondin-2, R-spondin-3, R-spondin-4, somatostatin, octreotide, gastrin, Ghrelin, inhibitors of COX-2, antioxidants, vitamin E, sucralfate, lysophosphatidic acid, lysophosphatidic acid (LPA-2) receptor, and amifostine; wherein the pharmaceutical composition is administered to patient within at least 24 hours following radiation exposure. 2 Appeal 2016-001026 Application 12/633,631 Examiner’s Rejections 1.

Claims 10 and 17 stand rejected under pre-AIA 35 U.S.C. § 103(a) as unpatentable over Dor BioPharma, as evidenced by orBec® NDA, in view of Kim.8 (Id. at 20-21.) FINDINGS OF FACT We adopt the Examiner’s findings as our own, including with respect to the scope and content of the prior art and motivation to combine or modify the cited references. The following findings are included for emphasis and reference purposes. FF 1. The Examiner finds that “the Specification lacks sufficient direction to reasonably convey to one skilled in the relevant art that the inventors, at the time the application was filed, had possession of the method claimed, [wherein] the limitation reciting ‘within at least 24 hours’ is new matter.” (Final Act. 4—5.) FF 2. The Examiner finds that the Dor Press Release, as evidenced by orBec® NDA, anticipates claims 1 and 10. (Final Act. 5—6; Ans. 8—11.) The Dor Press Release indicates that oral BDP refers to oral beclomethasone dipropionate, and that oral BDP is the active ingredient in the orBec® drug. (Dor Press Release 1.) FF 3. The Examiner finds that Stergiopoulos teaches methods of treating inflammatory disorders of the gastrointestinal (GI) tract using topical active corticosteroids that can be administered at a dosage of 0.1 mg to 8 mg/day, that beclomethasone dipropionate (BDP) is the preferred topically active corticosteroid, and that the dosage is a result effective 8 Kim et al., Mitogenic Influence of Human R-Spondinl on the Intestinal Epithelium, 309 Science 1256-59 (2005) (“Kim”). 4 Appeal 2016-001026 Application 12/633,631 variable that is capable of being optimized. (Final Act. 11, citing Stergiopoulos claim 7 and 119.) FF 4. Stergiopoulos teaches co-administration of anti-inflammatory topical corticosteroids with non-steroidal anti-inflammatory drugs such as COX-2 inhibitors (i.e., ibuprofen, ketoprofen, indomethacin, and naproxen). (Stergiopoulos 118; see also Final Act. 11.) FF 5. The Examiner finds that Jacob is directed to compositions and methods for the treatment of ulcerative inflammatory and erosive disorders of mucous membranes, including disorders related to adverse side effects in radiation therapy, that growth factors such as keratinocyte growth factor (KGF) may be used alone or in combination with another active agent, and that BDP is a suitable steroidal anti-inflammatory agent. (Final Act. 15—16, citing Jacob Abstract and H 3, 31, 52, and 54.) FF 6. The Examiner finds that Hager teaches that lithium carbonate can reduce the adverse effects of tumor-destructive treatment, and can be used to treat patients following radiotherapy cost-effectively. (Final Act. 18, citing Hager 96.) FF 7. The Examiner finds that Kim is directed to the influence of R- Spondinl on the regeneration and proliferation of intestinal epithelium, and “was effective for preventing loss of epithelium proliferation and preserving the architecture of both the small intestine and the colon [] in mice exposed to damaging chemotherapy.” (Final Act. 20, citing Kim Abstract and 1258.) 5 Appeal 2016-001026 Application 12/633,631 DISCUSSION We adopt and agree with the Examiner’s findings, analysis, and conclusions as set forth in the Final Action (Final Act. 3—21) and Answer (Ans. 2—19). We discern no error in the Examiner’s rejections. Rejection No. 1 — Written Description Issue Whether the Specification’s description shows that Appellants were in possession of the method recited in claims 5 and 10. Analysis The Examiner finds that Appellants’ response filed March 10, 2014, introduced new matter into the claims. (Final Act 3.) In particular, the Examiner finds that amended claims 5 and 10 “recite a newly added wherein clause requiring that the beclomethasone dipropionate be administered ‘within at least 24 hours’ after the exposure to radiation.” (Id.) The Examiner also finds that “because the Specification describes administration prior to irradiation and 2 hours following irradiation, the recitation of ‘within at least 24 hours’ reads literally on embodiments outside the 0—2 hour range,” and thus “would not reasonably direct the skilled artisan to [a] range encompassed by ‘within at least 24 hours.’” (Id. at 4.) Appellants argue that claim 5 includes administration of a second compound (e.g., KGF), and that the Specification describes a clinical trial in which KGF was administered three days before and three days after total body irradiation. (Appeal Br. 13, citing Spec. 7,12.) Appellants also point to Examples 3 and 4 of the Specification “which states the BDP and BDP/KGF were administered starting after total body irradiation and until GI recovery.” (Appeal Br. 13.) As for claim 10, Appellants argue that “one 6 Appeal 2016-001026 Application 12/633,631 of skill in the art would know that symptoms of acute radiation . . . typically occur with the first 24 hours following exposure.” {Id. at 14.) We find that the Examiner has the better position. As an initial matter, we agree with the Examiner that ‘“wherein administration occurs within at least 24 hours following exposure to the radiation’, reads on administration that occurs at any time within 24 hours and after 24 hours, without any upper limit.” (Final Act. 6.) We also find that the case of In re Wertheim, 541 F.2d 257 (CCPA 1976), is instructive with respect to the terminology “at least.” In Wertheim, the court found that the claim recitation of “at least 35%” solids content read on embodiments outside of the described solid contents range of 25—60%. Id. at 263. Moreover, the court found that, by pointing to this fact, the USPTO satisfied the initial burden of establishing that “persons skilled in the art would not recognize in the disclosure a description of the invention defined by the claims.” Id. at 263-64. Appellants contend that, unlike the situation in Wertheim where the court found that “Appellants have adduced no evidence to carry [this] burden [as to] claim 1,” the recitation of “at least 24 hours” is reasonably conveyed to one of skill in the art. (Reply Br. 6 (quoting Wertheim, 541 F.2d at 264).) To the contrary, we find that Appellants rely solely on arguments, such as the argument that the Examiner is requiring literal support in the Specification,9 and the argument as to what “one of skill in the 9 The Examiner’s statement that support “is found for the embodiment wherein BDP was given 2 hours after total body irradiation . . . and prior to irradiation” is not a requirement of literal support for the claim terminology at issue. (Final Act. 3—4.) 7 Appeal 2016-001026 Application 12/633,631 art would understand.” (Reply Br. 6—7.) However, those arguments cannot take the place of evidence. See In re Pearson, 494 F.2d 1399, 1405 (CCPA 1974) (“Attorney’s argument in a brief cannot take the place of evidence.”). Appellants also argue that “[t]he crucial understanding for the present invention is that the lower limit for the start of administration of BDP occur[s] within 24 hours of lethal radiation exposure.” (Reply Br. 7.) However, the claims recite “within at least 24 hours,” not “within 24 hours,” and the claim recitation reads on embodiments outside the written description. (See Final Act. 3—5; Wertheim, 541 F.2d at 263—64.) Conclusion A preponderance of evidence of record fails to establish that Appellants were in possession of the method recited in claims 5 and 10. Accordingly, the rejection of claims 5 and 10 under 35U.S.C. § 112, first paragraph, is affirmed. Claims 13 and 15—17 were not separately argued and fall with claim 10. Rejection No. 2 — Anticipation Issue Whether a preponderance of evidence of record supports the Examiner’s rejection under 35 U.S.C. § 102(b). Analysis Claim 1 Appellants contest the anticipation finding by arguing that the Examiner has combined the Dor Press Release and the orBec® NDA to achieve the anticipation rejection, and that Appellants “can point to several elements of claim 1 which are not disclosed in either of the 102 references.” (Appeal Br. 17.) In particular, Appellants argue that the Dor Press Release 8 Appeal 2016-001026 Application 12/633,631 “fails to disclose release of BDP locally in the small bowel sufficient to expose a metabolite thereof,” and that “there is no disclosure of BDP as the sole drug administered for treatment of tissue damage due to epithelial apoptosis.” {Id. at 16—17.) We are not persuaded. Appellants are reminded that in considering the disclosure of a reference for anticipation, “it is proper to take into account not only specific teachings of the reference but also the inferences which one skilled in the art would reasonably be expected to draw therefrom.” In re Preda, 401 F.2d 825, 826 (CCPA 1968). Moreover, “[ujnder the principles of inherency, if the prior art necessarily functions in accordance with, or includes, the claimed limitations, it anticipates.” MEHL/Biophile Int’l Corp. v. Milgraum, 192 F.3d 1362, 1365 (Fed. Cir. 1999). The anticipation rejection is based on the Dor Press Release, as evidenced by orBec® NDA.10 (Final Act. 5—6.) As explained by the Examiner, the orBec® NDA evidences that the functional limitations of claims 1 and 10 “necessarily flow from the administration of orBec®.” (Ans. 9.) For example, the functional language regarding “release of BDP locally in the small bowel sufficient to expose a metabolite thereof’ is evidenced by the orBec® NDA’s description that BDP’s primary metabolite, 17-BMP, has systemic exposure and that one tablet referenced in the Dor Press Release releases BDP in the mid-small intestine.* 11 (orBec® NDA 10.) 10 See MPEP § 2131.01 regarding use of extra references to show that a characteristic not expressly disclosed in a § 102 reference is inherent. 11 We also acknowledge, but are unpersuaded by, Appellants’ argument that the art does not inherently teach “that a dosage released solely in the small bowel will treat acute radiation injury” (Reply Br. 9, emphasis added), at 9 Appeal 2016-001026 Application 12/633,631 Contrary to Appellants’ contention regarding the disclosure of BDP as the sole drug, the Dor Press Release discloses that “orBec® is formulated for oral administration as a single product consisting of two tablets; one tablet is intended to release BDP in the proximal portions of the GI tract and the other tablet is intended to release BDP in the distal portions of the GI tract.” (Dor Press Release 2.) The Dor Press Release also states that oral BDP may be “given alone or in combination” for treatment of “destruction of epithelial tissue” and “loss of epithelial cells.” (Dor Press Release 1.) Claim 10 Appellants repeat the same arguments advanced in connection with claim 1 and they are unpersuasive for the reasons set forth above. Appellants also argue in the Reply Brief that the Dor Press Release is not enabling. (Reply Br. 10-11.) However, because that argument was not properly raised in the Appeal Brief, it is waived.12 See 37 C.F.R. §§41.37(c)(l)(iv), 41.41(b)(2). least because claim 1 is not so limited. See In re Self, 671 F.2d 1344, 1348 (CCPA 1982) (rejecting arguments “not based on limitations appearing in the claims”). 12 Appellants merely state in the Appeal Brief that “it is not enough for the reference(s) cited as anticipatory to be enabling of the claimed invention.” (Appeal Br. 17.) This is not sufficiently specific to explain Appellants’ position, as required under Rule 41.37, especially given that Appellants bear the burden to show non-enablement of a reference once the Examiner has made a proper prima facie case of anticipation. See In re Antor Media Corp., 689 F.3d 1282, 1288—89 (Fed. Cir. 2012). Further, the portion of the Answer to which Appellants direct their Reply Brief argument appears in the Final Rejection, and thus is not “responsive to an argument raised in the examiner’s answer” as permitted under Rule 41.41. (See Final Act. 6,115.) 10 Appeal 2016-001026 Application 12/633,631 Conclusion A preponderance of evidence of record supports the Examiner’s rejection of claims 1 and 10 under 35 U.S.C. § 102(b). Rejection Nos. 3—6 — Obviousness Issue Whether a preponderance of evidence of record supports the Examiner’s rejections under pre-AIA 35 U.S.C. § 103(a). Analysis Rejection No. 3 includes claim 1 and Rejection Nos. 3—6 include claim 10. However, claims 1 and 10 are anticipated, and “anticipation is the epitome of obviousness.” In re McDaniel, 293 F.3d 1379, 1385 (Fed. Cir. 2002) (citations omitted). Accordingly, the rejections of claims 1 and 10 for obviousness are affirmed. The remaining claims subject to obviousness rejections are addressed below. Rejection No. 3 Dependent claims 4 and 13, and independent claim 5, recite that the effective amount of the topically active corticosteroid is 8 mg/day. (Corrected Claims App. 38—39.) Claim 5 also recites the administration of a second compound, such as COX-2 inhibitors. (Id.) Claim 4 Claim 4 is dependent on claim 1. (Id. at 38.) Appellants argue that the Examiner has failed to present a prima facie case of obviousness based on the combination of prior art, and that “[t]he mere fact that inflammation is a symptom of each condition does not suggest to one of skill in the art that the treatment would necessarily be effective for all conditions which include 11 Appeal 2016-001026 Application 12/633,631 inflammation.” (Appeal Br. 22—23.) Appellants argue further that Stergiopoulos is directed to the treatment of autoimmune conditions, and that “[o]nly undue experimentation or impermissible hindsight would allow one of ordinary skill to reach ... a conclusion” that a treatment regimen for autoimmune conditions would effectively treat cell damage resulting from lethal radiation exposure. (Id. at 23.) We are not persuaded. Both the Dor Press Release and Stergiopoulos teach the use of BDP to treat inflammation in the GI tract and, as explained by the Examiner, it would have been obvious to provide BDP as taught by the Dor Press Release at a dose (8 mg/day) as taught by Stergiopoulos for treating inflammation in the gastrointestinal tract. (Final Act. 11; FF 3.) Moreover, that Stergiopoulos may use BDP to treat inflammation in connection with autoimmune conditions does not diminish its appropriate combination with the Dor Press Release. See In re Beattie, 974 F.2d 1309, 1312 (Fed. Cir. 1992) (explaining that “the law does not require that the references be combined for the reasons contemplated by the inventor”) (citing cases); see also In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006). We are likewise unpersuaded that providing the BDP of the Dor Press Release at a dosage of 8 mg/day would require undue experimentation or that the Examiner has engaged in impermissible hindsight. Appellants point to no evidence that any of the Examiner’s findings were beyond the level of ordinary skill at the time of the invention or could have been taken only from Appellants’ Specification. See In re McLaughlin, 443 F.2d 1392, 1395 (CCPA 1971). Accordingly, for these reasons and the reasons set forth above in connection with claim 1, we affirm the rejection of claim 4. 12 Appeal 2016-001026 Application 12/633,631 Claim 13 Claim 13 is dependent on claim 10. (Corrected Claims App. 39.) Appellants advance essentially the same arguments as advanced in connection with claim 4, and those arguments are unpersuasive for the reasons set forth above. In addition, Appellants argue an “unexpected result is that BDP is effective at treating the symptoms of lethal radiation exposure as the instantly claimed dosage.” (Appeal Br. 28.) We are unpersuaded because that statement is merely attorney argument, unsupported by evidence. Unexpected results must be established by factual evidence, and “[m]ere argument or conclusory statements in the specification does not suffice.” In re Geisler, 116 F.3d 1465, 1470 (Fed. Cir. 1997) (quoting In re De Blauwe, 736 F.2d 699, 705 (Fed. Cir. 1984)). Accordingly, for these reasons and the reasons set forth above in connection with claim 10, we affirm the rejection of claim 13. Claim 5 Appellants advance essentially the same arguments as advanced in connection with claim 4, and those arguments are unpersuasive for the reasons set forth above. In addition, Appellants argue that “the Examiner’s assertion that Stergiopoulos’ teaching of co-administration of BDP with non steroidal anti-inflammatory drugs renders claim 5 obvious is unsupported by the prior art of record” and “requires the Examiner to use impermissible hindsight.” (Appeal Br. 26.) We are not persuaded for the reasons set forth above, and because Stergiopoulos expressly teaches co-administration of BDP and a COX-2 inhibitor. (FF 3 and 4.) 13 Appeal 2016-001026 Application 12/633,631 Rejection No. 4 Claim 15 is dependent on claim 10 and further recites the administration of an effective dosage of KGF. (Corrected Claims App. 40.) Appellants argue that the combined teachings of the references would suggest to those of ordinary skill in the art that they should explore through experimentation a method for administering a treatment for acute radiation exposure by administration of BDP in combination with KGF and nothing more. Without experimentation, one of skill in the art would have found the combined teachings lacking for suggesting the method as recited in claim 10 or 15 because one of skill in the art would understand that methods of treatment are not necessarily transferrable between conditions. (Appeal Br. 31.) We understand Appellants’ argument to be that there would not have been a reasonable expectation of success in combining the references because some experimentation is required. However, the reasonable expectation of success requirement “refers to the likelihood of success in combining references to meet the limitations of the claimed invention.” Intelligent Bio-Systems, Inc. v. Illumina Cambridge Ltd., 821 F.3d 1359, 1367 (Fed. Cir. 2016). Here, the combination is the administration of BDP and another compound (KGF) that is known to be effective in treating radiation patients. (FF 5.) Moreover, obviousness does not require absolute predictability of success. See In re O’Farrell, 853 F.2d 894, 903 (Fed. Cir. 1988) (“Obviousness does not require absolute predictability of success. Indeed, for many inventions that seem quite obvious, there is no absolute predictability of success until the invention is reduced to practice.”). In this case, experimentation to verily the combination suggested by the prior art does not obviate the obviousness of the combination. See Pfizer, Inc. v. 14 Appeal 2016-001026 Application 12/633,631 Apotex, Inc., 480 F.3d 1348, 1364 (Fed. Cir. 2007) (“[A] rule of law equating unpredictability to patentability, applied in this case, would mean that any new salt. . . would be separately patentable, simply because the formation and properties of each salt must be verified through testing.”). Accordingly, for these reasons and the reasons set forth above in connection with claim 10, we affirm the rejection of claim 15. Rejection No. 5 Claim 16 is dependent on claim 10 and further recites the administration of an effective dosage amount of lithium carbonate. (Corrected Claims App. 40.) Here, the combination is the administration of BDP and another compound (lithium carbonate) that is known to be effective in treating radiation patients. (FF 6.) Appellants repeat the same arguments advanced in connection with claim 15, substituting lithium carbonate for KGF and claim 16 for claim 15. (Appeal Br. 33.) Those arguments are equally unpersuasive for the reasons set forth above in connection with claim 15. Accordingly, for these reasons and the reasons set forth above in connection with claim 10, we affirm the rejection of claim 16. Rejection No. 6 Claim 17 is dependent on claim 10 and further recites the administration of R-spondin-1. (Corrected Claims App. 40.) Here, the combination is the administration of BDP and another compound (R- spondin-1) that is known to be effective for preventing loss of epithelium proliferation and preserving the architecture of both the small intestine and the colon. (FF 7.) Appellants repeat the same arguments advanced in connection with claim 15, substituting R-spondin-1 for KGF and claim 17 15 Appeal 2016-001026 Application 12/633,631 for claim 15. (Appeal Br. 35—36.) Those arguments are equally unpersuasive for the reasons set forth above in connection with claim 15. Accordingly, for these reasons and the reasons set forth above in connection with claim 10, we affirm the rejection of claim 17. Conclusion of Law A preponderance of evidence of record supports the Examiner’s rejections of claims 1, 4, 5, 10, 13, and 15—17 under 35 U.S.C. § 103(a) (Rejection Nos. 3—6). SUMMARY We affirm the rejections of all claims on appeal. TIME PERIOD FOR RESPONSE No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a).
