SCHEINER, FRANCISCO C. PRATS, and JACQUELINE WRIGHT BONILLA, Administrative Patent Judges. PRATS, Administrative Patent Judge. DECISION ON APPEAL This appeal under 35 U.S.C. § 134 involves claims to treating amyotrophic lateral sclerosis (ALS). The Examiner entered rejections for anticipation and obviousness. We have jurisdiction under 35 U.S.C. § 6(b). We affirm three of the Examiner‟s four anticipation rejections. We also affirm the Examiner‟s obviousness rejection. Appeal 2011-001820 Application 11/931,326 2 STATEMENT OF THE CASE Claims 1, 20-22, and 59-75 stand rejected and appealed (App. Br. 2). Claims 1 and 65, the independent claims, illustrate the appealed subject matter and read as follows: Claim 1. A method of treating amyotrophic lateral sclerosis in a mammal, consisting of administering to the mammal in need thereof, a hematopoietic factor selected from the group consisting of mammalian granulocyte colony stimulating factor (G-CSF), human G-CSF, a protein having at least 90% homology to SEQ ID NO:37 and G-CSF activity, a protein having at least 90% homology to SEQ ID NO:38 and G-CSF activity, a protein having at least 90% homology to SEQ ID NO:39 and GCSF activity, PEG-modified G-CSF, or a combination thereof in an amount sufficient to treat the amyotrophic lateral sclerosis. Claim 65. A method of treating amyotrophic lateral sclerosis caused by a SOD1 mutation in a mammal, comprising administering to the mammal in need thereof, a hematopoietic factor selected from the group consisting of mammalian granulocyte colony stimulating factor (G-CSF), human G-CSF, a protein having at least 90% homology to SEQ ID NO:37 and G-CSF activity, a protein having at least 90% homology to SEQ ID NO:38 and G-CSF activity, a protein having at least 90% homology to SEQ ID NO:39 and GCSF activity, PEG-modified G-CSF, or a combination thereof in an amount sufficient to treat the amyotrophic lateral sclerosis. The following rejections are before us for review: (1) Claims 1, 20-22, 60-68, and 70-75, under 35 U.S.C. § 102(b) as anticipated Faustman „346 1 (Ans. 4-6); (2) Claims 1, 20-22, 60-68, and 70-75, under 35 U.S.C. §§ 102(a) and 102(e) as anticipated by Faustman „689 2 (Ans. 6-8); 1 WO 99/43346 A1 (published September 2, 1999). 2 U.S. Patent App. Pub. No. 2002/0106689 A1 (published August 8, 2002). Appeal 2011-001820 Application 11/931,326 3 (3) Claims 1, 20-22, and 59-75, under 35 U.S.C. §§ 102(a) and 102(e) as anticipated by Chajut 3 (Ans. 8-9); (4) Claims 65-75, under 35 U.S.C. § 102(b) as anticipated by North 4 (Ans. 9-10); and (5) Claims 59 and 69, under 35 U.S.C. § 103(a) as obvious over Faustman „346 or Faustman „689 (Ans. 10-14). ANTICIPATION – THE FAUSTMAN PUBLICATIONS Appellants contend that “Faustman US „689 is the national stage filing of Faustman WO „346” (App. Br. 6). While that fact is not apparent from either publication, the relevant disclosures of Faustman „346 and Faustman „689 do in fact appear to be substantially the same. We therefore consider the Examiner‟s anticipation rejections over both Faustman publications together. As stated in In re Oetiker, 977 F.2d 1443, 1445 (Fed. Cir. 1992): [T]he examiner bears the initial burden . . . of presenting a prima facie case of unpatentability. . . . After evidence or argument is submitted by the applicant in response, patentability is determined on the totality of the record, by a preponderance of evidence with due consideration to persuasiveness of argument. Appellants‟ arguments do not persuade us that a preponderance of the evidence fails to support the Examiner‟s prima facie case that the Faustman publications anticipate claim 1. 3 U.S. Patent App. Pub. No. 2002/0198150 A1 (published December 26, 2002). 4 Will A. North et al., Reversible Granulocytopenia in Association with Riluzole Therapy, 34 Annals of Pharmacotherapy 322-32 (2000). Appeal 2011-001820 Application 11/931,326 4 Claim 1 recites a method of treating amyotrophic lateral sclerosis (ALS) in a mammal. The method consists of administering a hematopoietic factor, which may be mammalian granulocyte colony stimulating factor (G- CSF), to the mammal in need of such treatment. The G-CSF must be administered in an amount sufficient to treat the ALS. Faustman „346 discloses “a method of treating an autoimmune disease in a mammal, comprising administering to a mammal suspected of suffering from an autoimmune disease an agent which restores NFκB activity in an amount and for a time sufficient to result in normal NFκB activity in the mammal” (Faustman „346 at p. 16; see also Faustman „689 at [0104]). Faustman then discloses that, “[p]referably, the agent is selected from the group that consists of a protein and a nucleic acid that encodes that protein” and, further, that “[i]t is preferred that the protein is selected from the group that includes . . . granulocyte colony-stimulating factor . . .” (Faustman „346 at pp. 16-17; see also Faustman „689 at [0106]-[0107]). Faustman then discloses that, “[i]n another preferred embodiment, the autoimmune disease is selected from the group that includes those diseases listed above” (Faustman „346 at p. 17), among which is ALS (see id. at p. 7; see also Faustman „689 at [0112] and [0031]). Thus, as the Examiner pointed out, Faustman describes treating the claimed disorder with the claimed therapeutic agent. We acknowledge, as Appellants argue, that in an anticipation rejection “it is not enough that the prior art reference . . . includes multiple, distinct teachings that [an ordinary] artisan might somehow combine to achieve the claimed invention.” NetMoneyIN, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1371 (Fed. Cir. 2008). Rather, the reference “must clearly and Appeal 2011-001820 Application 11/931,326 5 unequivocally disclose the claimed [invention] or direct those skilled in the art to the [invention] without any need for picking, choosing, and combining various disclosures not directly related to each other by the teachings of the cited reference.” Id. (quoting In re Arkley, 455 F.2d 586, 587 (CCPA 1972). We also acknowledge that Faustman lists ALS alongside about 56 other diseases that can be treated (see Faustman „346 at page 7), and that G-CSF is listed alongside about 23 other agents that can be used to treat those diseases (see id. at 17). However, because the specifically listed diseases and specifically listed treating agents do not number in the thousands, or multiple thousands, or more, we are not persuaded that Faustman‟s description of which diseases to treat, and which agents to use, amounts to a meaningless description of treating any of a “plethora” of disorders, as Appellants argue (App. Br. 6). To the contrary, because the Faustman publications lay out the NFκB-related treatment methods in a sequential manner that evidences a direct relationship between a list of specific “preferred” treatment agents (see Faustman „346 at p. 16; Faustman „689 at [0107]), and a list of specific “preferred” diseases to be treated with those agents (id. Faustman „346 at 17; Faustman „689 at [0112]), we agree with the Examiner that improper picking and choosing of unrelated disclosures is not required to “at once envisage” claim 1‟s treatment of ALS with G-CSF. See In re Petering, 301 F.2d 676, 681 (CCPA 1962) (chemical compounds held anticipated where reference disclosing generic formula also included preferences for claimed substituents). Further, we are not persuaded that Appellants have advanced evidence adequately demonstrating that the Faustman publications did not enable an Appeal 2011-001820 Application 11/931,326 6 ordinary artisan to treat ALS with G-CSF. We note the disclosures in Silani 5 and Jackson 6 that the hypothesized link between autoimmunity and ALS is waning in popularity, as well as the disclosures in Jackson and Jerusalem 7 that attempts at treating ALS with immunologically-based had been unsuccessful (see Silani at p. 25 (abstract); Jackson at p. 34; Jerusalem at p. S218). As Appellants point out, however, “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.” In re Gleave, 560 F.3d 1331, 1335 (Fed. Cir. 2009) (citing Impax Labs., Inc. v. Aventis Pharms. Inc., 545 F.3d 1312, 1314 (Fed. Cir. 2008); Rasmusson v. SmithKline Beecham Corp., 413 F.3d 1318, 1326 (Fed. Cir. 2005)). Thus, the fact that autoimmunity might not be the most popular causative hypothesis for ALS among those skilled in the art does not provide sufficient clear or specific evidence to persuade us that an ordinary practitioner, armed with Faustman‟s disclosure of treating ALS with G-CSF, would have been able to practice Faustman‟s method only through undue experimentation. Therefore, as Appellants‟ arguments do not persuade us that the Examiner erred in maintaining the anticipation rejection of claim 1 over the Faustman publications, we affirm the Examiner‟s rejections of that claim 5 Vincenzo Silani et al., Patogeneza SLA: implikacje dla leczenia, NEUR. NEUROCHIR. POL. Supp.I 25-39 (2001). 6 Carlayne E. Jackson and Wilson W. Bryan, Amyotrophic Lateral Sclerosis, 18 SEMINARS IN NEUROLOGY 27-39 (1998). 7 F. Jerusalem et al., ALS, 47 NEUROLOGY Suppl. 4 S218-S220 (1996). Appeal 2011-001820 Application 11/931,326 7 over those references. As they were not argued separately, claims 20-22 and 60-64 fall with claim 1. See 37 C.F.R. § 41.37(c)(1)(vii). Appellants‟ arguments also fail to persuade us that the Examiner erred in maintaining the anticipation rejections over the Faustman publications as to claim 65. Claim 65, like claim 1, encompasses treating mammals having ALS with G-CSF, but limits the treated subjects to those having ALS “caused by a SOD1 mutation” (App. Br. 17). We note Silani‟s disclosure that the SOD1 mutation in the superoxide dismutase gene is observed in a subset of ALS sufferers: Besides the free radical hypothesis raised by the identification of Superoxide Dismutase 1 mutations in a subset of familiar Amyotrophic Lateral Sclerosis (ALS) patients, three etiopathogenic hypotheses for sporadic ALS, namely autoimmune, neurofilament, and glutamate toxicity, have attracted interest in the last few years. The role of autoimmunity in ALS has been seriously questioned. (Silani at p. 25.) We also note Appellants‟ assertion that, in their hands, G-CSF exhibited a trend toward increasing life expectancy in a transgenic mouse model of ALS that includes an SOD1 mutation (see, e.g. Spec. 163 (Example 33)). Appellants have not, however, advanced clear or specific evidence suggesting that, despite the fact that they suffer from the same disorder, the subset of ALS sufferers exhibiting the SOD1 mutation would have been viewed sufficiently differently from ALS sufferers generally, such that an ordinary artisan viewing Faustman‟s disclosure of treating ALS with G-CSF would have failed to envisage treating the SOD1-carrying patients with that agent. Thus, as Appellants‟ arguments do not persuade us that the Examiner erred in maintaining the anticipation rejections of claim 65 over the Appeal 2011-001820 Application 11/931,326 8 Faustman publications we affirm those rejections as well. Claims 66-68 and 70-75 fall with claim 65. See 37 C.F.R. § 41.37(c)(1)(vii). OBVIOUSNESS – THE FAUSTMAN PUBLICATIONS Claims 59 and 69 depend, respectively, from claims 1 and 65, and both require the hematopoietic factor, which may be G-CSF, to be administered daily (see App. Br. 16 (claim 59); see also id. at 18 (claim 69)). While the Examiner conceded that the Faustman publications did not describe daily administration of G-CSF, the Examiner reasoned that an ordinary artisan practicing Faustman‟s ALS treatment would have considered it obvious to “modify the teachings of Faustman by formulating a daily dosage regimen, because both Faustman disclosures clearly provide guidance to one of ordinary skill in the art as to how to formulate treatment regimens for proteins” (Ans. 13). In traversing this rejection, Appellants rely solely on their previous arguments directed to the anticipation rejection (see App. Br. 11 (“[A]s discussed above, Faustman does not actually disclose the treatment of ALS in the manner that is claimed and as such Faustman cannot render Claim 59 obvious.”)). Thus, as Appellants point to no specific deficiency as to the Examiner‟s prima facie case of obviousness, and as we are not persuaded, for the reasons discussed above, that the Examiner erred in maintaining the anticipation rejection, we affirm the Examiner‟s obviousness rejections over the Faustman publications. Appeal 2011-001820 Application 11/931,326 9 ANTICIPATION – CHAJUT The Examiner rejected claims 1, 20-22, and 59-75, all of the pending claims, as anticipated by Chajut under 35 U.S.C. §§ 102(a) and 102(e) (see Ans. 8-9). Appellants do not argue any of the claims subject to this ground of rejection separately (see App. Br. 11-13). We select claim 1 as representative of the rejected claims. See 37 C.F.R. § 41.37(c)(1)(vii). Appellants‟ arguments do not persuade us that a preponderance of the evidence fails to support the Examiner‟s prima facie case that Chajut anticipates claim 1. Chajut discloses the use of “growth factors that stimulate migration and differentiation of stem cells, particularly colony stimulating factors (CSFs), in order to promote and enhance recovery from tissue trauma and ischemic events, including ischemia of the central nervous system, as well as for use in preventing or diminishing chronic degenerative changes” (Chajut [0024]). Chajut then states: The compositions of the present invention may also be effective in treating certain chronic degenerative diseases that are characterized by gradual selective neuronal loss. In this connection, the compositions of the present invention are contemplated as therapeutically effective in the treatment of Parkinson‟s disease, Alzheimer‟s disease, epilepsy, depression, ALS (Amyotrophic lateral sclerosis), Huntington‟s disease and any other disease-induced dementia (such as HIV-induced dementia, for example). These effects will be achieved by administering an agent that stimulates the mobilization of bone marrow-derived stem cells into the bloodstream. Representative agents useful in the methods of the invention include, for example, granulocyte- Appeal 2011-001820 Application 11/931,326 10 colony stimulating factor (G-CSF), granulocyte-macrophage- colony stimulating factor (GM-CSF), stem cell factor (SCF), interleukin-3 (IL-3) and interleukin-6 (IL-6). These factors have all been shown to be capable of mobilizing bone marrow- derived stem cells . . . . (Chajut [0027]-[0028] (emphases added, citations omitted).) We acknowledge that, in addition to ALS, Chajut lists additional disorders that may be treated according to its methods. We also acknowledge that, in addition to G-CSF, Chajut lists a number of other therapeutic agents that may be used to treat those disorders. However, given the sequential and related manner in which Chajut presents the treated disorders and the treating agents, as well as the limited number of choices of both, Appellants‟ arguments do not persuade us that Chajut fails to adequately describe, in the manner required under § 102, claim 1‟s process of treating ALS with G-CSF. Appellants argue that Chajut does not demonstrate, by presentation of a working example, infiltration of stem cells activated by G-CSF into the central nervous system (see App. Br. 11-12). Appellants argue that the disclosures of Chen 8 and Smith 9 similarly cast doubt on whether an ordinary artisan would have reasonably expected that the mechanism of action proposed by Chajut would provide an effective treatment of ALS (see id. at 13). 8 Jieli Chen et al., Therapeutic Benefit of Intravenous Administration of Bone Marrow Stromal Cells After Cerebral Ischemia in Rats, 32 STROKE 1005- 1011 (2001). 9 Richard A. Smith et al., Pharmacokinetics and tolerability of ventricularly administered superoxide dismutase in monkeys and preliminary clinical observations in familial ALS, 129 J. NEUR. SCI. (Suppl.) 13-18 (1995). Appeal 2011-001820 Application 11/931,326 11 We are not persuaded. We note, in an experiment which assessed the therapeutic effect of intravenously administered stem cells, that Chen posited that “[d]isruption of the blood-brain barrier may facilitate selective entry of [stem cells] into ischemic brain compared with nonischemic contralateral cerebral tissue” (Chen at p. 1010). We also note that, because of the presence of the blood-brain barrier, Smith evaluated direct central nervous system administration of the superoxide dismutase protein as a potential treatment for ALS (see Smith at p. 14). Appellants do not, however, point to any clear or specific teaching in Chen or Smith that directly discusses the methods described in Chajut. Moreover, as noted above, “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.” In re Gleave, 560 F.3d at 1335 (internal quotations removed). Consistently, in Rasmusson v. SmithKline Beecham, for example, the Federal Circuit reversed the BPAI‟s conclusion that a reference describing a cancer treatment was not enabled for anticipation purposes, despite the fact that the Board had based its non-enablement conclusion upon findings supporting the premise that an ordinary artisan would not have believed that the method described in the reference would be effective, as well as the fact that the reference itself lacked proof of efficacy. See Rasmusson, 413 F.3d at 1326. We are therefore not persuaded that Appellants have advanced evidence adequately demonstrating that the method of treating ALS with G-CSF described in Chajut is not enabled for anticipation purposes. Accordingly, as Appellants‟ arguments do not persuade us that the Examiner erred in maintaining the anticipation rejection of claim 1 over Chajut, we Appeal 2011-001820 Application 11/931,326 12 affirm that rejection. Claims 20-22 and 59-75 fall with claim 1. See 37 C.F.R. § 41.37(c)(1)(vii). ANTICIPATION – NORTH The Examiner also rejected claims 65-75 under 35 U.S.C. § 102(b) as anticipated by North (Ans. 9-10). As Appellants point out, and as pointed out above, claim 65 encompasses treating mammals having ALS with G-CSF, but limits the treated subjects to those having ALS “caused by a SOD1 mutation” (App. Br. 17). In this instance, we agree with Appellants that a preponderance of the evidence does not support the Examiner‟s prima facie case of anticipation. In particular, we are not persuaded that the Examiner has advanced sufficient evidence to support a finding that the patient treated in North inherently suffered from ALS caused by an SOD1 mutation, as claim 65 requires. It is well settled in the law of anticipation that the “very essence of inherency is that one of ordinary skill in the art would recognize that a reference unavoidably teaches the property in question.” Agilent Technologies, Inc. v. Affymetrix, Inc., 567 F.3d 1366, 1383 (Fed. Cir. 2009) (emphasis added); see also In re Oelrich, 666 F.2d 578, 581 (CCPA 1981) (“Inherency, however, may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient.”). Thus, if “the disclosure is sufficient to show that the natural result flowing from the operation as taught would result in the performance of the questioned function, it seems to be well settled that the disclosure should be Appeal 2011-001820 Application 11/931,326 13 regarded as sufficient.” Oelrich, 666 F. 2d at 581 (quoting Hansgirg v. Kemmer, 102 F.2d 212, 214 (CCPA 1939)). Here, North describes treating a single ALS patient with filgramstim (North 322, abstract), which is undisputed on this record to be a “pharmaceutical version of G-CSF” (Ans. 3). North explains that the ALS patient experienced granulocytopenia as an apparent side effect of the riluzole that was being administered to treat the ALS (North 322, abstract). North reported that “[b]lood counts returned to normal with discontinuation of riluzole and administration of filgramstim” (id.). However, as pointed out in Silani, only a subset of ALS sufferers has the SOD1 mutation (see Silani 25 (abstract)). Thus, because the Examiner has pointed to no evidence supporting a finding that North‟s patient necessarily had the SOD1 mutation, the evidence of record at best shows that there was a possibility that North‟s patient had the SOD1 mutation. As noted above, however, inherency may not be established by probabilities or possibilities. In re Oelrich, 666 F.2d at 581. The Examiner argues that “[w]hether a person develops ALS because of a SOD1 mutation or glutamate toxicity is a distinction without a difference. The person of ordinary skill in the art, as evidenced by Smith et al. above, would not differentiate in his or her treatment between a patient with FALS [familial ALS] or ALS (Ans. 41). We acknowledge the statement in Smith (a different reference) cited by the Examiner: “[T]he similar clinical course and histopathology of sporadic ALS and FALS, whether or not there is an SOD gene mutation, suggest that common molecular mechanisms, and hence a common approach Appeal 2011-001820 Application 11/931,326 14 to treatment, may apply to all forms of this devastating disease” (Smith 13 (citation omitted). We also acknowledge that this statement supports a finding that an ordinary artisan would have understood that a generic description of treating ALS would not differentiate between patients exhibiting different hypothetical causative factors, such as SOD1 mutation. Unlike the Faustman and Chajut rejections discussed above, however, the Examiner points to no disclosure in North that describes treating ALS sufferers, as a generic class of patients, with G-CSF. Rather, as also noted above, North describes treating a single patient, and the Examiner points to no evidence suggesting that patient was necessarily a member of the subset of ALS sufferers having the SOD1 mutation. Accordingly, as we are not persuaded that the Examiner has advanced adequate evidence to support a finding that the sole patient treated in North necessarily had ALS caused by an SOD1 mutation as required by claim 65, we reverse the Examiner‟s rejection of that claim, and its dependents over North. SUMMARY We affirm the Examiner‟s rejection of claims 1, 20-22, 60-68, and 70- 75, under 35 U.S.C. § 102(b) as anticipated Faustman „346. We also affirm the Examiner‟s rejection of claims 1, 20-22, 60-68, and 70-75, under 35 U.S.C. §§ 102(a) and 102(e) as anticipated by Faustman „689. We also affirm the Examiner‟s rejection of claims 1, 20-22, and 59- 75, under 35 U.S.C. §§ 102(a) and 102(e) as anticipated by Chajut. Appeal 2011-001820 Application 11/931,326 15 We also affirm the Examiner‟s rejection of claims 59 and 69, under 35 U.S.C. § 103(a) as obvious over Faustman „346 or Faustman „689. However, we reverse the Examiner‟s rejection of claims 65-75, under 35 U.S.C. § 102(b) as anticipated by North. TIME PERIOD No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a).

DECISION ON APPEAL This appeal under 35 U.S.C. § 134 involves claims to treating amyotrophic lateral sclerosis (ALS). The Examiner entered rejections for anticipation and obviousness. We have jurisdiction under 35 U.S.C. § 6(b). We affirm three of the Examiner‟s four anticipation rejections. We also affirm the Examiner‟s obviousness rejection. Appeal 2011-001820 Application 11/931,326 2 STATEMENT OF THE CASE Claims 1, 20-22, and 59-75 stand rejected and appealed (App. Br. 2). Claims 1 and 65, the independent claims, illustrate the appealed subject matter and read as follows: Claim 1. A method of treating amyotrophic lateral sclerosis in a mammal, consisting of administering to the mammal in need thereof, a hematopoietic factor selected from the group consisting of mammalian granulocyte colony stimulating factor (G-CSF), human G-CSF, a protein having at least 90% homology to SEQ ID NO:37 and G-CSF activity, a protein having at least 90% homology to SEQ ID NO:38 and G-CSF activity, a protein having at least 90% homology to SEQ ID NO:39 and GCSF activity, PEG-modified G-CSF, or a combination thereof in an amount sufficient to treat the amyotrophic lateral sclerosis. Claim 65. A method of treating amyotrophic lateral sclerosis caused by a SOD1 mutation in a mammal, comprising administering to the mammal in need thereof, a hematopoietic factor selected from the group consisting of mammalian granulocyte colony stimulating factor (G-CSF), human G-CSF, a protein having at least 90% homology to SEQ ID NO:37 and G-CSF activity, a protein having at least 90% homology to SEQ ID NO:38 and G-CSF activity, a protein having at least 90% homology to SEQ ID NO:39 and GCSF activity, PEG-modified G-CSF, or a combination thereof in an amount sufficient to treat the amyotrophic lateral sclerosis. The following rejections are before us for review: (1) Claims 1, 20-22, 60-68, and 70-75, under 35 U.S.C. § 102(b) as anticipated Faustman „346 1 (Ans. 4-6); (2) Claims 1, 20-22, 60-68, and 70-75, under 35 U.S.C. §§ 102(a) and 102(e) as anticipated by Faustman „689 2 (Ans. 6-8); 1 WO 99/43346 A1 (published September 2, 1999). 2 U.S. Patent App. Pub. No. 2002/0106689 A1 (published August 8, 2002). Appeal 2011-001820 Application 11/931,326 3 (3) Claims 1, 20-22, and 59-75, under 35 U.S.C. §§ 102(a) and 102(e) as anticipated by Chajut 3 (Ans. 8-9); (4) Claims 65-75, under 35 U.S.C. § 102(b) as anticipated by North 4 (Ans. 9-10); and (5) Claims 59 and 69, under 35 U.S.C. § 103(a) as obvious over Faustman „346 or Faustman „689 (Ans. 10-14). ANTICIPATION – THE FAUSTMAN PUBLICATIONS Appellants contend that “Faustman US „689 is the national stage filing of Faustman WO „346” (App. Br. 6). While that fact is not apparent from either publication, the relevant disclosures of Faustman „346 and Faustman „689 do in fact appear to be substantially the same. We therefore consider the Examiner‟s anticipation rejections over both Faustman publications together. As stated in In re Oetiker, 977 F.2d 1443, 1445 (Fed. Cir. 1992): [T]he examiner bears the initial burden . . . of presenting a prima facie case of unpatentability. . . . After evidence or argument is submitted by the applicant in response, patentability is determined on the totality of the record, by a preponderance of evidence with due consideration to persuasiveness of argument. Appellants‟ arguments do not persuade us that a preponderance of the evidence fails to support the Examiner‟s prima facie case that the Faustman publications anticipate claim 1. 3 U.S. Patent App. Pub. No. 2002/0198150 A1 (published December 26, 2002). 4 Will A. North et al., Reversible Granulocytopenia in Association with Riluzole Therapy, 34 Annals of Pharmacotherapy 322-32 (2000). Appeal 2011-001820 Application 11/931,326 4 Claim 1 recites a method of treating amyotrophic lateral sclerosis (ALS) in a mammal. The method consists of administering a hematopoietic factor, which may be mammalian granulocyte colony stimulating factor (G- CSF), to the mammal in need of such treatment. The G-CSF must be administered in an amount sufficient to treat the ALS. Faustman „346 discloses “a method of treating an autoimmune disease in a mammal, comprising administering to a mammal suspected of suffering from an autoimmune disease an agent which restores NFκB activity in an amount and for a time sufficient to result in normal NFκB activity in the mammal” (Faustman „346 at p. 16; see also Faustman „689 at [0104]). Faustman then discloses that, “[p]referably, the agent is selected from the group that consists of a protein and a nucleic acid that encodes that protein” and, further, that “[i]t is preferred that the protein is selected from the group that includes . . . granulocyte colony-stimulating factor . . .” (Faustman „346 at pp. 16-17; see also Faustman „689 at [0106]-[0107]). Faustman then discloses that, “[i]n another preferred embodiment, the autoimmune disease is selected from the group that includes those diseases listed above” (Faustman „346 at p. 17), among which is ALS (see id. at p. 7; see also Faustman „689 at [0112] and [0031]). Thus, as the Examiner pointed out, Faustman describes treating the claimed disorder with the claimed therapeutic agent. We acknowledge, as Appellants argue, that in an anticipation rejection “it is not enough that the prior art reference . . . includes multiple, distinct teachings that [an ordinary] artisan might somehow combine to achieve the claimed invention.” NetMoneyIN, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1371 (Fed. Cir. 2008). Rather, the reference “must clearly and Appeal 2011-001820 Application 11/931,326 5 unequivocally disclose the claimed [invention] or direct those skilled in the art to the [invention] without any need for picking, choosing, and combining various disclosures not directly related to each other by the teachings of the cited reference.” Id. (quoting In re Arkley, 455 F.2d 586, 587 (CCPA 1972). We also acknowledge that Faustman lists ALS alongside about 56 other diseases that can be treated (see Faustman „346 at page 7), and that G-CSF is listed alongside about 23 other agents that can be used to treat those diseases (see id. at 17). However, because the specifically listed diseases and specifically listed treating agents do not number in the thousands, or multiple thousands, or more, we are not persuaded that Faustman‟s description of which diseases to treat, and which agents to use, amounts to a meaningless description of treating any of a “plethora” of disorders, as Appellants argue (App. Br. 6). To the contrary, because the Faustman publications lay out the NFκB-related treatment methods in a sequential manner that evidences a direct relationship between a list of specific “preferred” treatment agents (see Faustman „346 at p. 16; Faustman „689 at [0107]), and a list of specific “preferred” diseases to be treated with those agents (id. Faustman „346 at 17; Faustman „689 at [0112]), we agree with the Examiner that improper picking and choosing of unrelated disclosures is not required to “at once envisage” claim 1‟s treatment of ALS with G-CSF. See In re Petering, 301 F.2d 676, 681 (CCPA 1962) (chemical compounds held anticipated where reference disclosing generic formula also included preferences for claimed substituents). Further, we are not persuaded that Appellants have advanced evidence adequately demonstrating that the Faustman publications did not enable an Appeal 2011-001820 Application 11/931,326 6 ordinary artisan to treat ALS with G-CSF. We note the disclosures in Silani 5 and Jackson 6 that the hypothesized link between autoimmunity and ALS is waning in popularity, as well as the disclosures in Jackson and Jerusalem 7 that attempts at treating ALS with immunologically-based had been unsuccessful (see Silani at p. 25 (abstract); Jackson at p. 34; Jerusalem at p. S218). As Appellants point out, however, “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.” In re Gleave, 560 F.3d 1331, 1335 (Fed. Cir. 2009) (citing Impax Labs., Inc. v. Aventis Pharms. Inc., 545 F.3d 1312, 1314 (Fed. Cir. 2008); Rasmusson v. SmithKline Beecham Corp., 413 F.3d 1318, 1326 (Fed. Cir. 2005)). Thus, the fact that autoimmunity might not be the most popular causative hypothesis for ALS among those skilled in the art does not provide sufficient clear or specific evidence to persuade us that an ordinary practitioner, armed with Faustman‟s disclosure of treating ALS with G-CSF, would have been able to practice Faustman‟s method only through undue experimentation. Therefore, as Appellants‟ arguments do not persuade us that the Examiner erred in maintaining the anticipation rejection of claim 1 over the Faustman publications, we affirm the Examiner‟s rejections of that claim 5 Vincenzo Silani et al., Patogeneza SLA: implikacje dla leczenia, NEUR. NEUROCHIR. POL. Supp.I 25-39 (2001). 6 Carlayne E. Jackson and Wilson W. Bryan, Amyotrophic Lateral Sclerosis, 18 SEMINARS IN NEUROLOGY 27-39 (1998). 7 F. Jerusalem et al., ALS, 47 NEUROLOGY Suppl. 4 S218-S220 (1996). Appeal 2011-001820 Application 11/931,326 7 over those references. As they were not argued separately, claims 20-22 and 60-64 fall with claim 1. See 37 C.F.R. § 41.37(c)(1)(vii). Appellants‟ arguments also fail to persuade us that the Examiner erred in maintaining the anticipation rejections over the Faustman publications as to claim 65. Claim 65, like claim 1, encompasses treating mammals having ALS with G-CSF, but limits the treated subjects to those having ALS “caused by a SOD1 mutation” (App. Br. 17). We note Silani‟s disclosure that the SOD1 mutation in the superoxide dismutase gene is observed in a subset of ALS sufferers: Besides the free radical hypothesis raised by the identification of Superoxide Dismutase 1 mutations in a subset of familiar Amyotrophic Lateral Sclerosis (ALS) patients, three etiopathogenic hypotheses for sporadic ALS, namely autoimmune, neurofilament, and glutamate toxicity, have attracted interest in the last few years. The role of autoimmunity in ALS has been seriously questioned. (Silani at p. 25.) We also note Appellants‟ assertion that, in their hands, G-CSF exhibited a trend toward increasing life expectancy in a transgenic mouse model of ALS that includes an SOD1 mutation (see, e.g. Spec. 163 (Example 33)). Appellants have not, however, advanced clear or specific evidence suggesting that, despite the fact that they suffer from the same disorder, the subset of ALS sufferers exhibiting the SOD1 mutation would have been viewed sufficiently differently from ALS sufferers generally, such that an ordinary artisan viewing Faustman‟s disclosure of treating ALS with G-CSF would have failed to envisage treating the SOD1-carrying patients with that agent. Thus, as Appellants‟ arguments do not persuade us that the Examiner erred in maintaining the anticipation rejections of claim 65 over the Appeal 2011-001820 Application 11/931,326 8 Faustman publications we affirm those rejections as well. Claims 66-68 and 70-75 fall with claim 65. See 37 C.F.R. § 41.37(c)(1)(vii). OBVIOUSNESS – THE FAUSTMAN PUBLICATIONS Claims 59 and 69 depend, respectively, from claims 1 and 65, and both require the hematopoietic factor, which may be G-CSF, to be administered daily (see App. Br. 16 (claim 59); see also id. at 18 (claim 69)). While the Examiner conceded that the Faustman publications did not describe daily administration of G-CSF, the Examiner reasoned that an ordinary artisan practicing Faustman‟s ALS treatment would have considered it obvious to “modify the teachings of Faustman by formulating a daily dosage regimen, because both Faustman disclosures clearly provide guidance to one of ordinary skill in the art as to how to formulate treatment regimens for proteins” (Ans. 13). In traversing this rejection, Appellants rely solely on their previous arguments directed to the anticipation rejection (see App. Br. 11 (“[A]s discussed above, Faustman does not actually disclose the treatment of ALS in the manner that is claimed and as such Faustman cannot render Claim 59 obvious.”)). Thus, as Appellants point to no specific deficiency as to the Examiner‟s prima facie case of obviousness, and as we are not persuaded, for the reasons discussed above, that the Examiner erred in maintaining the anticipation rejection, we affirm the Examiner‟s obviousness rejections over the Faustman publications. Appeal 2011-001820 Application 11/931,326 9 ANTICIPATION – CHAJUT The Examiner rejected claims 1, 20-22, and 59-75, all of the pending claims, as anticipated by Chajut under 35 U.S.C. §§ 102(a) and 102(e) (see Ans. 8-9). Appellants do not argue any of the claims subject to this ground of rejection separately (see App. Br. 11-13). We select claim 1 as representative of the rejected claims. See 37 C.F.R. § 41.37(c)(1)(vii). Appellants‟ arguments do not persuade us that a preponderance of the evidence fails to support the Examiner‟s prima facie case that Chajut anticipates claim 1. Chajut discloses the use of “growth factors that stimulate migration and differentiation of stem cells, particularly colony stimulating factors (CSFs), in order to promote and enhance recovery from tissue trauma and ischemic events, including ischemia of the central nervous system, as well as for use in preventing or diminishing chronic degenerative changes” (Chajut [0024]). Chajut then states: The compositions of the present invention may also be effective in treating certain chronic degenerative diseases that are characterized by gradual selective neuronal loss. In this connection, the compositions of the present invention are contemplated as therapeutically effective in the treatment of Parkinson‟s disease, Alzheimer‟s disease, epilepsy, depression, ALS (Amyotrophic lateral sclerosis), Huntington‟s disease and any other disease-induced dementia (such as HIV-induced dementia, for example). These effects will be achieved by administering an agent that stimulates the mobilization of bone marrow-derived stem cells into the bloodstream. Representative agents useful in the methods of the invention include, for example, granulocyte- Appeal 2011-001820 Application 11/931,326 10 colony stimulating factor (G-CSF), granulocyte-macrophage- colony stimulating factor (GM-CSF), stem cell factor (SCF), interleukin-3 (IL-3) and interleukin-6 (IL-6). These factors have all been shown to be capable of mobilizing bone marrow- derived stem cells . . . . (Chajut [0027]-[0028] (emphases added, citations omitted).) We acknowledge that, in addition to ALS, Chajut lists additional disorders that may be treated according to its methods. We also acknowledge that, in addition to G-CSF, Chajut lists a number of other therapeutic agents that may be used to treat those disorders. However, given the sequential and related manner in which Chajut presents the treated disorders and the treating agents, as well as the limited number of choices of both, Appellants‟ arguments do not persuade us that Chajut fails to adequately describe, in the manner required under § 102, claim 1‟s process of treating ALS with G-CSF. Appellants argue that Chajut does not demonstrate, by presentation of a working example, infiltration of stem cells activated by G-CSF into the central nervous system (see App. Br. 11-12). Appellants argue that the disclosures of Chen 8 and Smith 9 similarly cast doubt on whether an ordinary artisan would have reasonably expected that the mechanism of action proposed by Chajut would provide an effective treatment of ALS (see id. at 13). 8 Jieli Chen et al., Therapeutic Benefit of Intravenous Administration of Bone Marrow Stromal Cells After Cerebral Ischemia in Rats, 32 STROKE 1005- 1011 (2001). 9 Richard A. Smith et al., Pharmacokinetics and tolerability of ventricularly administered superoxide dismutase in monkeys and preliminary clinical observations in familial ALS, 129 J. NEUR. SCI. (Suppl.) 13-18 (1995). Appeal 2011-001820 Application 11/931,326 11 We are not persuaded. We note, in an experiment which assessed the therapeutic effect of intravenously administered stem cells, that Chen posited that “[d]isruption of the blood-brain barrier may facilitate selective entry of [stem cells] into ischemic brain compared with nonischemic contralateral cerebral tissue” (Chen at p. 1010). We also note that, because of the presence of the blood-brain barrier, Smith evaluated direct central nervous system administration of the superoxide dismutase protein as a potential treatment for ALS (see Smith at p. 14). Appellants do not, however, point to any clear or specific teaching in Chen or Smith that directly discusses the methods described in Chajut. Moreover, as noted above, “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.” In re Gleave, 560 F.3d at 1335 (internal quotations removed). Consistently, in Rasmusson v. SmithKline Beecham, for example, the Federal Circuit reversed the BPAI‟s conclusion that a reference describing a cancer treatment was not enabled for anticipation purposes, despite the fact that the Board had based its non-enablement conclusion upon findings supporting the premise that an ordinary artisan would not have believed that the method described in the reference would be effective, as well as the fact that the reference itself lacked proof of efficacy. See Rasmusson, 413 F.3d at 1326. We are therefore not persuaded that Appellants have advanced evidence adequately demonstrating that the method of treating ALS with G-CSF described in Chajut is not enabled for anticipation purposes. Accordingly, as Appellants‟ arguments do not persuade us that the Examiner erred in maintaining the anticipation rejection of claim 1 over Chajut, we Appeal 2011-001820 Application 11/931,326 12 affirm that rejection. Claims 20-22 and 59-75 fall with claim 1. See 37 C.F.R. § 41.37(c)(1)(vii). ANTICIPATION – NORTH The Examiner also rejected claims 65-75 under 35 U.S.C. § 102(b) as anticipated by North (Ans. 9-10). As Appellants point out, and as pointed out above, claim 65 encompasses treating mammals having ALS with G-CSF, but limits the treated subjects to those having ALS “caused by a SOD1 mutation” (App. Br. 17). In this instance, we agree with Appellants that a preponderance of the evidence does not support the Examiner‟s prima facie case of anticipation. In particular, we are not persuaded that the Examiner has advanced sufficient evidence to support a finding that the patient treated in North inherently suffered from ALS caused by an SOD1 mutation, as claim 65 requires. It is well settled in the law of anticipation that the “very essence of inherency is that one of ordinary skill in the art would recognize that a reference unavoidably teaches the property in question.” Agilent Technologies, Inc. v. Affymetrix, Inc., 567 F.3d 1366, 1383 (Fed. Cir. 2009) (emphasis added); see also In re Oelrich, 666 F.2d 578, 581 (CCPA 1981) (“Inherency, however, may not be established by probabilities or possibilities. The mere fact that a certain thing may result from a given set of circumstances is not sufficient.”). Thus, if “the disclosure is sufficient to show that the natural result flowing from the operation as taught would result in the performance of the questioned function, it seems to be well settled that the disclosure should be Appeal 2011-001820 Application 11/931,326 13 regarded as sufficient.” Oelrich, 666 F. 2d at 581 (quoting Hansgirg v. Kemmer, 102 F.2d 212, 214 (CCPA 1939)). Here, North describes treating a single ALS patient with filgramstim (North 322, abstract), which is undisputed on this record to be a “pharmaceutical version of G-CSF” (Ans. 3). North explains that the ALS patient experienced granulocytopenia as an apparent side effect of the riluzole that was being administered to treat the ALS (North 322, abstract). North reported that “[b]lood counts returned to normal with discontinuation of riluzole and administration of filgramstim” (id.). However, as pointed out in Silani, only a subset of ALS sufferers has the SOD1 mutation (see Silani 25 (abstract)). Thus, because the Examiner has pointed to no evidence supporting a finding that North‟s patient necessarily had the SOD1 mutation, the evidence of record at best shows that there was a possibility that North‟s patient had the SOD1 mutation. As noted above, however, inherency may not be established by probabilities or possibilities. In re Oelrich, 666 F.2d at 581. The Examiner argues that “[w]hether a person develops ALS because of a SOD1 mutation or glutamate toxicity is a distinction without a difference. The person of ordinary skill in the art, as evidenced by Smith et al. above, would not differentiate in his or her treatment between a patient with FALS [familial ALS] or ALS (Ans. 41). We acknowledge the statement in Smith (a different reference) cited by the Examiner: “[T]he similar clinical course and histopathology of sporadic ALS and FALS, whether or not there is an SOD gene mutation, suggest that common molecular mechanisms, and hence a common approach Appeal 2011-001820 Application 11/931,326 14 to treatment, may apply to all forms of this devastating disease” (Smith 13 (citation omitted). We also acknowledge that this statement supports a finding that an ordinary artisan would have understood that a generic description of treating ALS would not differentiate between patients exhibiting different hypothetical causative factors, such as SOD1 mutation. Unlike the Faustman and Chajut rejections discussed above, however, the Examiner points to no disclosure in North that describes treating ALS sufferers, as a generic class of patients, with G-CSF. Rather, as also noted above, North describes treating a single patient, and the Examiner points to no evidence suggesting that patient was necessarily a member of the subset of ALS sufferers having the SOD1 mutation. Accordingly, as we are not persuaded that the Examiner has advanced adequate evidence to support a finding that the sole patient treated in North necessarily had ALS caused by an SOD1 mutation as required by claim 65, we reverse the Examiner‟s rejection of that claim, and its dependents over North. SUMMARY We affirm the Examiner‟s rejection of claims 1, 20-22, 60-68, and 70- 75, under 35 U.S.C. § 102(b) as anticipated Faustman „346. We also affirm the Examiner‟s rejection of claims 1, 20-22, 60-68, and 70-75, under 35 U.S.C. §§ 102(a) and 102(e) as anticipated by Faustman „689. We also affirm the Examiner‟s rejection of claims 1, 20-22, and 59- 75, under 35 U.S.C. §§ 102(a) and 102(e) as anticipated by Chajut.
