VALEK, Administrative Patent Judges. VALEK, Administrative Patent Judge. DECISION ON APPEAL Appellant submits this appeal under 35 U.S.C. § 134(a) involving claims to a method for identifying a candidate agent for treating depression through the use of a rodent animal model.1 We have jurisdiction under 35 U.S.C. § 6(b). We AFFIRM. STATEMENT OF THE CASE According to the Specification, “[c]urrent non-human animal models of depression are non-specific” and therefore “[t]here is a need in the art for 1 We use the word “Appellant” to refer to “applicant” as defined in 37 C.F.R. § 1.42. Appellant identifies the Board of Trustees of the Leland Stanford Junior University as the real party in interest. Appeal Br. 3. Appeal 2019-003058 Application 14/385,331 2 improved non-human animal models of depression.” Spec. ¶ 3. “The present disclosure provides non-human optogenetic animal models of depression.” Id. ¶ 4. The Specification explains that these models “express[] a light- responsive opsin (e.g., a light-responsive ion channel; a light-responsive ion pump; etc.) in a neuron of the animal” that, when activated “by exposure of the light-activated opsin to light[,] modulates the behavior of the animal.” Id. ¶ 32. According to the Specification, In some cases, the active optogenetic inhibitor of neuronal activity (light-responsive opsin) is a halorhodopsin (e.g., NpHR) that promotes hyperpolarization of the DA neurons when activated by light at or near the VTA. Hyperpolarization of the DA neurons inhibits activity of these neurons. The non- human animal model exhibits characteristics of depression when the light-responsive opsin is activated by light. A test agent is administered to the non-human animal model. When DA neurons of the VTA are exposed to light of a wavelength (e.g., amber light) that activates that light-responsive opsin, a test agent that is a candidate agent for treating depression will ameliorate at least one symptom of depression in the non- human animal model. Id. ¶ 133. Claims 1–6 and 28–30 are on appeal and can be found in the Claims Appendix of the Appeal Brief. Claim 1 is representative of the claims on appeal. It reads as follows: 1. A method for identifying a candidate agent for treating depression in an individual, comprising: activating, with a light source, a hyperpolarizing light- responsive opsin polypeptide expressed in ventral tegmental area (VTA) dopaminergic neurons in a rodent, wherein the light- responsive opsin polypeptide hyperpolarizes the VTA dopaminergic neurons in response to light of an activating Appeal 2019-003058 Application 14/385,331 3 wavelength from the light source, thereby inhibiting the dopaminergic neurons and inducing depression in the rodent; contacting the rodent with a test agent, and determining the effect of the test agent on a behavior of the rodent in a depression assay, wherein reduction in a depressive behavior of the rodent contacted with the test agent, compared to the behavior of a control rodent that has not been contacted with the test agent, indicates that the test agent is a candidate agent for treating depression. Appeal Br. App. i. Appellant seeks review of the following rejections: I. Claims 1–6, 28, and 29 under 35 U.S.C. § 103 as obvious over Castagné,2 Deisseroth,3 Chuong,4 Zhang,5 Zhao,6 Tsai,7 Friedman,8 Knöpfel,9 and Stuber;10 and 2 Vincent Castagné et al., Rodent Models of Depression: Forced Swim and Tail Suspension Behavioral Despair Tests in Rats and Mice, Current Protocols in Pharmacology 5.8.1–5.8.14 (2010) (“Castagné”). 3 US 2009/0099038 A1, published April 16, 2009 (“Deisseroth”). 4 US 2012/0121542 A1, published May 17, 2012 (“Chuong”). 5 US 2010/0190229 A1, published July 29, 2010 (“Zhang”). 6 Shengli Zhao et al., Improved Expression of Halorhodopsin for Light- Induced Silencing of Neuronal Activity, 36 Brain Cell Biology 141–154 (2008) (“Zhao”). 7 Hsing-Chen Tsai et al., Phasic Firing in Dopaminergic Neurons Is Sufficient for Behavioral Conditioning, 324 Science 1080–1084 (2009) (“Tsai”). 8 Alexander Friedman et al., Programmed Acute Electrical Stimulation of Ventral Tegmental Area Alleviates Depressive-Like Behavior, 34 Neuropsychopharmacology 1057–1066 (2009) (“Friedman”). 9 Thomas Knöpfel et al., Remote Control of Cells, 5 Nature Nanotechnology 560–561 (2010) (“Knöpfel”). 10 Garret D.

Claims 29 and 30 under 35 U.S.C. § 103 as obvious over Castagné, Deisseroth, Chuong, Zhang, Zhao, Tsai, Friedman, Knöpfel, Stuber, Gradinaru 2008,11 and Gradinaru 2010.12 Appeal Br. 4; Reply Br. 2, 15.13 Appellant does not argue any claim separately from independent claim 1, nor does Appellant present arguments for the rejection of claims 29 and 30 that beyond the arguments it presents for the first obviousness rejection. Accordingly, we analyze the rejections together, focusing on claim 1, which is representative for all of Appellant’s arguments. The issue is whether the preponderance of the evidence supports Examiner’s finding that claim 1 is obvious over the cited prior art. Findings of Fact FF1. Castagné teaches protocols for behavioral despair assays (i.e., forced swim and tail suspension tests) in rats and mice for screening potential antidepressant compounds. Castagné, Abstr. In these assays, the animal is contacted with a test compound and monitored for changes to “the duration of immobility when rodents are exposed to an inescapable situation.” Id. According to Castagné, the “[t]esting of new substances in the behavioral 11 Viviana Gradinaru et al., eNpHR: a Natronomonas Halorhodopsin Enhanced for Optogenetic Applications, 36 Brain Cell Biol. 129–139 (2008) (“Gradinaru 2008”). 12 Viviana Gradinaru et al., Molecular and Cellular Approaches for Diversifying and Extending Optogenetics, 141 Cell 154–165 (2010) (“Gradinaru 2010”). 13 In the Appeal Brief (at 2), claim 30 is incorrectly identified as included in Examiner’s first rejection. Appellant correctly identifies Examiner’s rejections in the Reply Brief. See Reply Br. 2, 15. Appeal 2019-003058 Application 14/385,331 5 despair and tail suspension tests allows a simple assessment of their potential antidepressant activity by the measurement of their effect on immobility.” Id. FF2. Castagné teaches that the behavioral despair tests it teaches for mice can “be employed for studies using transgenic animals.” Castagné, 5.8.4–5. FF3. Stuber teaches that “[w]ith the recent advances in the emerging field of optogenetics, it is now possible to selectively introduce light-gated ion channels and pumps into genetically defined populations of neurons to selectively stimulate or inhibit neuronal circuit elements with light.” Stuber, 341–42. Stuber explains that neurons can be transformed to express “[c]hannelrhodopsin-2 (ChR2)” for optical excitation and “light-sensitive chloride pump Halorhodopsin (NpHR)” for “optical inhibition of neural activity.” Id. at 342. According to Stuber, “[t]ransient inhibition of circuit components” by introduction of NpHR to select neurons “could potentially be even more valuable” than introducing ChR2 “for assaying the neural basis of behavior.” Id. at 342. FF4. Deisseroth teaches systems for screening drug candidates involving cell lines “having light responsive membrane ion switches,” such as “halorhodopsin (NpHR) in which amber light affects chloride (Cl-) ion flow so as to hyperpolarize neuronal membrane and make it resistant to firing.” Deisseroth, Abstr., ¶ 20. According to Deisseroth, the “system screens for ion-channel and ion-pump affecting compounds” by introducing “one or more drug candidates . . . to cells that were made optically responsive by the addition of the above mentioned proteins (ChR2 and NpHR).” Id. ¶ 21. FF5. Chuong teaches that light-activated ion pumps (LAIPs), including NpHR, can be expressed in “cells, tissues, and organisms.” Chuong ¶¶ 6, 68, Appeal 2019-003058 Application 14/385,331 6 106. Chuong teaches that such LAIPs can be used to “identify a candidate therapeutic agent or compound” by expressing a LAIP in [a] subject, contacting the subject with a light under suitable conditions to activate the LAIP and hyperpolarize the cell, and administering to the subject a candidate compound. The subject is then monitored to determine whether any change occurs that differs from a control effect in a subject. Thus, for example, a brain region may be silenced using a LAIP of the invention and a candidate compound may be administered to the brain and the effect of the compound determined by comparing the results with those of a control. Id. ¶¶ 114–15. FF6. Zhang teaches the expression of NpHR in target cells of whole animals, including C. elegans and mice, for “temporally-precise optical inhibition of neural activity.” Zhang ¶¶ 49, 58. The transformed cells in such animals are optically stimulated for “downregulation (e.g., neuronal hyperpolarization or alternatively chronic depolarization) of activity at the target.” Id. ¶ 9. For example, Zhang describes experiments involving “expression of NpHR-ECFP fusion protein in the body wall muscles of the nematode Caenorhabditis elegans using the muscle-specific myosin promoter (Pmyo-3).” Id. ¶¶ 142–44. According to Zhang, “photoactivation of NpHR immediately (within ± 150 ms) and essentially completely arrested swimming behavior” of the transformed animals. Id. at 142. FF7. Zhang teaches that “[b]oth NpHR and ChR2 can be functionally expressed and operate at high speed in the mammalian brain.” Zhang ¶ 146. Zhang further teaches that expression of these proteins “may be genetically targeted to specific classes of neurons” by using promotors associated with those neurons. Id. ¶ 147. Appeal 2019-003058 Application 14/385,331 7 FF8. Zhang teaches that “applications” of this technology “include those associated with any population of electrically-excitable cells, including neurons” and that “depression” is one of several diseases associated “with altered excitation-effector coupling.” Zhang ¶ 11. FF9. Zhao describes experiments involving “transgenic mice that express halorhodopsin (NpHR), a light-driven chloride pump that can be used to silence neuronal activity via light.” Zhao, Abstr. These mice were successfully transformed to express high levels of NpHr-YFP in cortical pyramidal neurons. Id. Zhao teaches that illumination of NpHR-positive neurons in acute brain slices led to hyperpolarization of neurons and produced rapid, reversible inhibition of neuronal firing. Thus, in principle NpHR in transgenic mice silences neurons in a light-inducible manner, raising the potential for its targeting to genetically distinct subpopulations of neurons in order to determine how neuronal activity in each neuron subtype shapes circuitry function and behavior. Id.at 151. FF10. Zhao reports that “NpHR-YFP expression led to the formation of numerous intracellular blebs, which may disrupt neuronal function.” Zhao, Abstr. Zhao teaches that this problem can be overcome “[b]y improving the signal peptide sequence and adding an ER export signal to NpHR-YFP” to “eliminate[] the formation of blebs and dramatically increase[] the membrane expression of NpHR-YFP.” Id. Zhao further teaches that mice expressing this “improved eNpHR in neurons will likely be a valuable tool for probing circuitry function.” Id.at 151. FF11. Tsai describes experiments in which mice were transformed to express “the light-activated cation channel channelrhodopsin-2 (ChR2)” in Appeal 2019-003058 Application 14/385,331 8 dopaminergic neurons (DA) of the ventral tegmental area (VTA). Tsai, 1081. The mice were then tested in “the conditioned place preference (CPP) paradigm . . . with use of phasic optogenetic stimulation [] of DA neurons as [the] conditioning stimuli.” Id. Tsai teaches that “phasic stimulation [of VTA domaminergic neurons transformed to express ChR2] sufficed to establish place preference in the absence of other reward.” Id. at 1083–84. According to Tsai, this type of “optogenetic approach . . . opens the door to exploring the causal, temporally precise, and behaviorally relevant interactions of DA neurons with other neuromodulatory circuits.” Id. at 1084. FF12. Friedman describes experiments involving acute electrical stimulation (AES) of DA neurons in the VTA of “Flinder Sensitive Line (FSL) rats, a genetic animal model of depression.” See Friedman, 1057–58. Friedman teaches that stimulation of VTA dopaminergic neurons in FSL rats decreased immobility and “has an antidepressant, and not stimulant, function.” Id. at 1062. In contrast, “[s]timulation of FSL rat brain in the deep mesencephalic nucleus (a nonspecific region which is not involved in motivation and emotion) resulted in no effect on depressive behavior.” Id. at 1063. FF13. Friedman discusses prior work by the same authors demonstrating that the “dopaminergic system is important in the depressive symptoms of FSL rats.” Id. at 1063 (citing Freedman 200814). For example, Freedman 2008 explains that the DA system plays a “key role . . . in depressive behavior” and that a “lower amount of long bursts in VTA neuronal activity may induce 14 Alexander Friedman et al., VTA Dopamine Neuron Bursting is Altered in an Animal Model of Depression and Corrected by Desipramine, 34 J. Mol. Neurosci. 201–209 (2008) (“Friedman 2008”). Appeal 2019-003058 Application 14/385,331 9 depressive states, as release of dopamine, which is important for reward and a feeling of well-being, requires many long bursts.” Freedman 2008, 208. FF14. Winter15 describes a study “test[ing] the differential implication of dopaminergic systems in depressive-like behavior in rats.” Winter, Abstr. In this study, the animals were chemically lesioned to degenerate DA neurons in the substantia nigra pars compacta (SNc) and the VTA and then monitored in various depression assays. Id. at 134. Winter teaches that “dopaminergic lesions of either the SNc or the VTA contribute to the manifestation of depressive-like behavior in rats” (id., Abstr.) and that degenerating DA neurons in these areas “induces depressive behavior in rats” (id. at 139). Analysis Examiner finds that Castagné teaches “a method for identifying a candidate agent for treating depression” comprising “contacting a rodent with a test agent” and “determining the effect of the test agent on a behavior of the rodent in a depression assay.” Ans. 4. Examiner acknowledges that Castagné does “not teach the rodent expresses an active optogenetic inhibitor of neuronal activity in [the] ventral tegmental area (VTA) dopaminergic neurons.” Id. at 5. Regarding the optogenetic limitations of claim 1, Examiner finds that Deisseroth, Chuong, and Zhang teach optogenetic systems, comprising cells modified to express NpHR, i.e., a “hyperpolarizing light-responsive opsin polypeptide,” to screen candidate agents both in culture and, with respect to 15 Christine Winter et al., Lesions of Dopaminergic Neurons in the Substantia Nigra Pars Compacta and in the Ventral Tegmental Area Enhance Depressive-Like Behavior in Rats, 184 Behavioral Brain Research 133–141 (2007). Appeal 2019-003058 Application 14/385,331 10 Zhang, a “transgenic non-human animal.” Id. at 5–6. In addition, Examiner determines that both Zhao and Tsai “evidence that the ordinary artisan was enabled to express optogenetic molecules, either ChR2 or NpHR, in rodent animals, including the VTA dopaminergic neurons, whereby ChR2 optogenetics is demonstrated to change the rodent’s behavior.” Id. at 6. According to Examiner, it would have been obvious to modify the depression assays taught in Castagné to employ “a genetically modified rodent expressing a NpHR hyperpolarizing light-responsive opsin polypeptide in a method for identifying a candidate agent for treating depression” because: a) the scientific and technical concepts of screening candidate compounds that modulate the activity of a hyperpolarizing light-responsive opsin polypeptide, wherein said hyperpolarizing light-responsive opsin polypeptide is NpHR, were known to the ordinary artisan (Deisseroth et al, Chuong et al, Zhang et al); b) the scientific and technical concepts of creating transgenic rodents whose genome comprises a hyperpolarizing light-responsive opsin polypeptide . . . were known to the ordinary artisan (Zhao et al, Zhang et al); c) the scientific and technical concepts that altering the activity of a hyperpolarizing light-responsive opsin polypeptide, to wit, a NpHR, in an animal will change the behavior of said animal were known and successfully reduced to practice by the ordinary artisan (Zhang et al); d) the involvement of the VTA in the process of depression and that the optogenetic system of Tsai et al provides precise in vivo stimulus, e.g., optogenetic stimulation and/or optogenetic stabilization, of the DA neurons in the VTA, thereby allowing the artisan to analyze the VTA DA neurons precisely when assaying candidate drugs for the treatment of depression [was known] (Tsai et al); e) Stuber taught that transient inhibition of circuit components (via NpHR-mediated optogenetics) could be Appeal 2019-003058 Application 14/385,331 11 potentially even more valuable (than ChR2-mediated activation) for assaying the neural basis of behavior; and f) Friedman et al taught that the ordinary artisan previously recognized the scientific and technical concepts of monitoring depressive-like behavior in animal models when modulating neural activity in the VTA. Ans. 22. We agree with and adopt Examiner’s findings of fact and reasoning regarding the scope and content of the prior art (Ans. 4–22; Final Act. 4–7; FF1–14) and determine that Examiner’s rejection of claims 1–6 and 28–30 is supported by the preponderance of the evidence. We address Appellant’s arguments below. Appellant’s arguments that the “cited art fails to disclose or suggest all claim elements” because each of the cited references taken individually is distinct from claim 1 is not persuasive. See Appeal Br. 7–10 (emphasis omitted). As explained above, Examiner’s rejection is based on the combination of those references. That combination, as articulated by Examiner, teaches or reasonably suggests all of the limitations of claim 1. See FF1–14. Appellant cannot overcome Examiner’s rejection “by attacking [the cited references] individually” because “the rejection is based upon the teachings of a combination of references.” See Soft Gel Techs., Inc. v. Jarrow Formulas, Inc., 864 F.3d 1334, 1341 (Fed. Cir. 2017) (quoting In re Merck & Co., 800 F.2d 1091, 1097 (Fed. Cir. 1986)). We are unpersuaded by Appellant’s argument that a skilled artisan would not be motivated to modify Castagné to incorporate a genetically modified rodent expressing NpHR. See Appeal Br. 10–12. Castagné teaches that transgenic animals can be used in its mice depression assays. FF2. Zhao teaches that transgenic mice expressing NpHR in neurons are a Appeal 2019-003058 Application 14/385,331 12 valuable tool for research. FF9–10. Thus, the record supports Examiner’s determination that a skilled artisan would be motivated to use Zhao’s transgenic mouse in Castagné’s depression assay. Appellant argues that “[s]ince Zhao disclosed that NpHR was overexpressed in cortical pyramidal neurons and lead to intracellular blebs, Zhao teaches away from use of such mice for further experiments.” Appeal. Br. 11. We disagree. Zhao teaches that these issues are successfully overcome by “improving the signal peptide sequence and adding an ER export signal to NpHR-YFP.” FF10. Moreover, Zhao affirmatively states that future transgenic mice expressing this improved eNpHR will be valuable research. Id. Thus, it certainly does not teach away from their use in the articulated combination of references. See Galderma Labs., L.P. v. Tolmar, Inc., 737 F.3d 731, 738 (Fed. Cir. 2013) (quoting DePuy Spine, Inc. v. Medtronic Sofamor Danek, Inc., 567 F.3d 1314, 1327 (Fed. Cir. 2009)) (explaining that a reference does not teach away if it “does not criticize, discredit, or otherwise discourage investigation into the invention claimed”). Appellant’s argument that the cited art provides no reason to include NpHR in dopaminergic neurons of the VTA is also unpersuasive. See Appeal Br. 11–12; Reply Br. 12–14. Friedman teaches that electrostimulation of VTA DA neurons provides an antidepressant effect in FSL rats. FF12. We agree with Examiner that it would “be a logical conclusion [from the teaching in Friedman] that enhancing inhibition of neuronal activity, in other words blocking stimulation (hyperpolarization as achieved via NpHR), would promote depression-like behavior.” Ans. 25. This finding is additionally supported by Friedman 2008 and Winter, which Examiner cites in the Answer. Ans. 27; FF13–14. Appeal 2019-003058 Application 14/385,331 13 We are not persuaded by Appellant’s argument that “one of ordinary skill in the art would not necessarily have chosen this minority population of neurons” because Cao16 reports “contradictory findings” concerning the role of VTA DA neurons in mediating depression-like symptoms in rats. Reply Br. 11–12. Cao states that the role of VTA DA neurons is “controversial” because some studies had shown that decreased activity of such neurons “contribute[s] to the pathogenesis of depression,” while others have “found increased activity of VTA DA neurons in stress-induced depression models.” Cao, 6. But even if there was some controversy in the art regarding to the precise role of VTA DA neurons in depression, “[o]bviousness does not require absolute predictability of success.” In re O’Farrell, 853 F.2d 894, 903 (Fed. Cir. 1988). Here, the record includes multiple references each of which independently suggests that inhibiting the activity of VTA DA neurons would induce depression-like symptoms in rodents. See FF12–14. Thus, we agree that Examiner’s rejection is supported by a preponderance of the evidence. Finally, we are not persuaded by Appellant’s unexpected results argument. Appellant urges that selective inhibition of VTA DA neurons by activating a hyperpolarizing-light responsive opsin in those neurons revealed a “depression-like phenotype” that was “unexpected” over the prior art. Appeal Br. 12 (citing Tye17). However, as explained above, Examiner has 16 Jun-Li Cao et al., Mesolimbic Dopamine Neurons in the Brain Reward Circuit Mediate Susceptibility to Social Defeat and Antidepressant Action, 30 J. Neurosci. 16453–16458 (2010) (“Cao”). 17 Kay M. Tye et al., Dopamine Neurons Modulate Neural Encoding and Expression of Depression-related Behavior, 493 Nature 537–541 (2013) (“Tye”). Appeal 2019-003058 Application 14/385,331 14 identified multiple references evidencing that a skilled artisan would have expected the inhibition of VTA DA neurons to induce depression-like symptoms in rodents. FF12–14. Tye does not provide sufficient evidence of unexpected results. Indeed, Tye confirms that DA neurons had previously “been hypothesized to be relevant” to depression. Tye, 537 (citing prior art). While it may have “not been possible to test this hypothesis directly . . . [using] existing therapeutic interventions [that were] unable to specifically target dopamine neurons” (id.), the record demonstrates that the optogenetic techniques recited in claim 1, and discussed in Tye, were known in the art (FF2–10) and known to be useful for targeting specific subpopulations of neurons in rodents (FF6–7, FF9, FF11). Thus, the record supports Examiner’s determination that Appellant’s “depression-like phenotype” is merely the expected result of applying known techniques to inhibit the activity of neurons known to be associated with depression-like symptoms in rodents. See Ans. 27. Such “[e]xpected beneficial results are evidence of obviousness” that do not overcome Examiner’s prima facie showing. See In re Gershon, 372 F.2d 535, 537 (CCPA 1967) (“Expected beneficial results are evidence of obviousness of a claimed invention, just as unexpected beneficial results are evidence of unobviousness thereof.”). For these reasons, we determine the preponderance of the evidence supports Examiner’s rejections. Accordingly, we affirm the rejections of Appeal 2019-003058 Application 14/385,331 15 claims 1–6 and 28–3018 under 35 U.S.C. § 103 as obvious over the cited prior art.

See 37 C.F.R. § 1.136(a)(1)(iv). AFFIRMED 18 Appellant relies on the same arguments for the second obviousness rejection of claims 29 and 30. See Reply Br. 15–17. We, therefore, affirm the second obviousness rejection for the same reasons as the first. Copy with citationCopy as parenthetical citation
