PRATS, JEFFREY N. FRED MAN, and JOHN G. NEW, Administrative Patent Judges. PRATS, Administrative Patent Judge. DECISION ON APPEAL This appeal under 35 U.S.C. § 134 involves claims to methods of recovering hydrocarbons from oil shale. The Examiner rejected the claims as obvious. We have jurisdiction under 35 U.S.C. § 6(b ). We affirm. 1 Raymond Wallage, the inventor, is the real party in interest of the present application. App. Br. 4. Appeal2016-005232 Application 13/338,883 STATEMENT OF THE CASE The following rejections are before us for review: (1) Claim 11, under 35 U.S.C. § 103(a) for obviousness over Sanderson,2 McDaniel, 3 Simpson, 4 Ritzman '930, 5 Ritzman '389, 6 Goklen,7 Cuypers, 8 and Vrvic9 (Final Action 5-16); (2) Claim 12, under 35 U.S.C. § 103(a) for obviousness over Sanderson, McDaniel, Simpson, Cuypers, and Vrvic (Final Action 16-21 ); (3) Claim 13, under 35 U.S.C. § 103(a) for obviousness over Sanderson, McDaniel, Simpson, Ritzman '930, Goklen, and Vrvic (Final Action 21-28); and (4) Claims 13 and 14, under 35 U.S.C. § 103(a) for obviousness over Sanderson, McDaniel, Simpson, Ritzman '930, Goklen, Vrvic, Cuypers, and Ritzman '389 (Final Action 29-30). Claim 11 illustrates the appealed subject matter and reads as follows (App. Br. 28): 2 US Patent No. 2,641,565 (issued Jun. 9, 1953). 3 US Patent No. 3,000,793 (issued Sept. 19, 1961). 4 US Patent App. Pub.

A method for recovering one or more hydrocarbons from oil shale, consisting of: a) providing a biomedium of microorganisms, water, sugar, and molasses, muriatic acid and yeast; b) providing oil shale; c) treating the oil shale with the biomedium; d) mechanically agitating by rotary tumbling the treated oil shale and biomedium approximately twelve hours to form a liquid suspension; and e) separating by centrifugation the liquid suspension to provide the one or more hydrocarbons. OBVIOUSNESS-CLAIM 11 The Examiner's Position In rejecting claim 11 as obvious, the Examiner cited Sanderson as describing a process that includes all of the basic steps of claim 11, including providing a microorganism-containing nutrient medium, providing oil shale, treating the oil shale with the medium, mechanically agitating the medium, and separating hydrocarbons, in the form of kerogen, from the treated medium. Final Action 6-8. To show that claim 11 's use of rotary tumbling would have been an obvious technique of mechanically agitating Sanderson's shale/nutrient medium/microorganism mixture, the Examiner pointed to Cuypers' s teaching that when, using microorganisms to remove hydrocarbons from soil, i.e. bioremediating or biodegrading the soil, rotary tumbling is a suitable method of mechanically agitating the microorganism/soil mixture. Final Action 8-9 (citing Cuypers 464 ). To show that claim 11 's use of centrifugation would have been an obvious technique of separating the hydrocarbons from Sanderson's microorganism-treated shale, the Examiner pointed to Vrvic's teaching that, 3 Appeal2016-005232 Application 13/338,883 when using the microorganism Bacillus circulans to demineralize oil shale to yield kerogen, centrifugation is a suitable method of separating the bacterial biomass from the treated oil shale substrates. Final Action 9-10 (citing Vrvic 1207). To show the obviousness of including claim 11 's sugar and molasses in Sanderson' nutrient medium, the Examiner noted that Pseudomonas jluorescens and members of the genus Clostridium were among the microorganisms identified by Sanderson as being suitable in its process. Final Action 6-7 (citing Sanderson 2:40-47), and cited McDaniel and Simpson to show that sugar and molasses were known to be useful carbon sources for those organisms. Final Action 10-12 (citing McDaniel, 1:47---60, 3:16-35; Simpson i-f 99). To show the obviousness of including yeast, as recited in claim 11, in Sanderson's shale/nutrient medium/microorganism mixture, the Examiner pointed to Ritzman '930's teaching that yeast was known in the art to be useful for dislodging and upgrading oil in situ in a production well. Final Action 12 (citing Ritzman '930, 1:41---65). To show the obviousness of including muriatic acid, as also recited in claim 11, in Sanderson's shale/nutrient medium/microorganism mixture, the Examiner noted Sanderson's teaching that acids released by microorganisms were thought to aid in releasing kerogen from shale (Final Action 13 (citing Sanderson 2:30-40), and also pointed to Goklen as teaching that moderate concentrations of RCl were useful for assisting in the isolation of kerogen from oil shale. Final Action 13 (citing Goklen 308). Lastly, to show the obviousness of performing Sanderson's mechanical agitation for approximately 12 hours, as also recited in claim 11, 4 Appeal2016-005232 Application 13/338,883 the Examiner noted Ritzman '389's disclosure that, when using aerobic bacteria to recover oil from inorganic solids such as oil shale, the release time can vary significantly depending on a number of factors. Final Action 14 (citing Ritzman '398, 3:32-35). The Examiner noted in particular that the ranges of release times described in Ritzman '389, between about 0.3 and 200 hours, and usually between 0.5 and about 20 or 50 hours, included the 12 hour period recited in claim 11. Id. The Examiner reasoned that, based on the teachings of Sanderson and Ritzman '389, an ordinary artisan would have recognized that "processing time of the oil shale by the bioremedium [sic] with agitation in a batch process is a result effective variable dependent on the concentration of the bacteria, degree of separation of product, oxygen availability, etc." Final Action 15. Accordingly, the Examiner reasoned, an ordinary artisan would have been motivated "to practice or test the parameter values widely to find those that are functional or optimal which then would be inclusive or cover that values as instantly claimed." Id. Discussion As stated in Jn re Oetiker, 977F.2d1443, 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. Appellant's arguments do not persuade us that a preponderance of the evidence fails to support the Examiner's prima facie case of obviousness as to claim 11. To the contrary, we adopt as our own the Examiner's findings 5 Appeal2016-005232 Application 13/338,883 as to the scope and content of the prior art, the Examiner's reasoning as to how and why an ordinary artisan would have combined the cited teachings of the references, and the Examiner's conclusion that claim 11 would have been prima facie obvious over the cited combination of references. As to Appellant's arguments, we acknowledge, as Appellant argues (App. Br. 14--16; Reply Br. 7-8), that McDaniel is not directed to recovering hydrocarbons from oil shale, but is instead directed to the use of microorganisms for the fermentative production of vitamins. See McDaniel, 1: 10-15 ("This invention relates to the production of therapeutically and nutritionally valuable substances by fermentation, and in particular to improved nutrient mediums for the microbiological production of vitamin substances having LLD activity or growth promoting properties for the microorganism Lactobacillus lactis Domer."). We acknowledge, as Appellant also argues (App. Br. 16-18; Reply Br. 8-9), that Simpson is not directed to recovering hydrocarbons from oil shale, but is instead directed to the use of microorganisms for the fermentative production of alcohols, such as ethanol and butanol. Simpson, abstract. Appellant does not persuade us, however, that McDaniel and Simpson do not qualify as analogous art. Even if a reference is in a different field of endeavor than the claimed invention, the reference is not non-analogous art if it is "is reasonably pertinent to the particular problem with which the inventor is involved." In re Klein, 647 F.3d 1343, 1348 (Fed. Cir. 2011) (internal quotations omitted). "A reference is reasonably pertinent if, even though it may be in a different field from that of the inventor's endeavor, it is one which, because of the matter with which it deals, logically would have commended itself to an 6 Appeal2016-005232 Application 13/338,883 inventor's attention in considering his problem." Id. (internal quotations omitted). In the instant case, the particular problem with which the inventor is involved is using microorganisms to recover hydrocarbons from oil shale. Spec. i-f 2 ("The inventive process is in the field of obtaining hydrocarbons from oil shale, and more specifically a process conducted at room temperature with the use of microorganisms.")(emphasis added). As explained in the Specification, and as claimed, this process requires the use of a nutrient medium for the microorganisms. Id. at i-fi-121-23. Indeed, Sanderson, a reference that undisputedly qualifies as analogous prior art, teaches that, when using microorganisms to recover hydrocarbons from oil shale, a nutrient medium for the microorganisms is required. See Sanderson, 3 :31-53 (nutrient medium inoculated with microorganisms mixed with shale and agitated); see also id. at 2:40-60 (identifying Pseudomonasfluorescens and members of the genus Clostridium as microorganisms suitable recovering kerogen from oil shale; describing nutrient medium) McDaniel explains that, when using microorganisms, including Pseudomonas jluorescens, to fermentatively produce certain vitamins (McDaniel, 1: 10-15, 3:44--52), the "usual nutrients include a source of carbon, nitrogen, inorganic salts and growth factors when required. The carbon may be provided by a carbohydrate such as dextrose, maltose, xylose, invert sugar, com syrup, beet molasses and the like" (id. at 3 :27-31 ). Simpson describes processes that "involve fermenting a suitable fermentable carbohydrate-containing feedstock (such as molasses sugars or sugars derived from other sources) in a suitable nutrient medium in the 7 Appeal2016-005232 Application 13/338,883 presence of Clostridium microorganisms which convert the sugar to a solvent mixture containing butanol, ethanol and acetone." Simpson i-f 99. Therefore, because the particular problem with which the inventor is involved necessarily implicates a determination of suitable nutrient media for the microorganisms used in the process, and because McDaniel and Simpson both provide disclosures as to suitable nutrient media for microorganisms known in the art to be useful in that process, we find that McDaniel and Simpson logically would have commended the inventor's attention in considering his problem. Accordingly, we are not persuaded that the Examiner erred in finding that McDaniel and Simpson qualify as analogous prior art. We agree with Appellant (Reply Br. 8-9), that in considering whether McDaniel and Simpson are analogous art, the determination must focus on the problem the inventor sought to address. See In re Klein, 647 F.3d at 1348 (A reference qualifies as analogous art if "it is one which, because of the matter with which it deals, logically would have commended itself to an inventor's attention in considering his problem.")( emphasis added). Nevertheless, that McDaniel and Simpson ultimately produce different products than the hydrocarbon produced by the claimed process does not persuade us that those references would have failed to command the inventor's attention, given that those references provide teachings regarding ingredients useful in nutrient media for microorganisms known in the art to be suitable in the inventor's claimed process for recovering hydrocarbons from oil shale. In sum, for the reasons discussed, Appellant does not persuade us that McDaniel and Simpson fail to qualify as analogous art. 8 Appeal2016-005232 Application 13/338,883 Appellant's arguments (App. Br. 19--20; Reply Br. 11-12), also do not persuade us that the Examiner erred in concluding that the 12 hour mechanical agitation time recited in claim 11 would have been obvious as a matter of routine optimization. It is well settled that "the discovery of an optimum value of a variable in a known process is usually obvious." Pfizer, Inc. v. Apotex, Inc., 480 F.3d 1348, 1368 (Fed. Cir. 2007). The rationale for determining the optimal parameters for prior art result effective variables "flows from the 'normal desire of scientists or artisans to improve upon what is already generally known."' Id. (quoting In re Peterson, 315 F.3d 1325, 1330 (Fed. Cir. 2003)). In general, however, "an applicant may overcome aprimafacie case of obviousness by establishing 'that the [claimed] range is critical, generally by showing that the claimed range achieves unexpected results relative to the prior art range."' In re Peterson, 315 F.3d at 1330 (quoting In re Geisler, 116 F.3d 1465, 1469-70 (Fed. Cir. 1997). In the instant case, we acknowledge that the disclosure identified by the Examiner regarding the reaction time in Ritzman '389 refers to the amount of time that the oil-containing inorganic material (e.g., oil sand) must react with the microorganism to effect oil release, and does not appear include any specific disclosure about the mixture being agitated. See Ritzman '389, 3:26-36. Nonetheless, Sanderson's mechanical agitation step is performed for the purpose of encouraging reaction between its microorganisms and the oil shale. See Sanderson 3 :49--51 ("This insures intimate and continued contact of the microorganisms with the shale particles."). Accordingly, we agree with the Examiner that an ordinary artisan would have understood that, like the reaction time in Ritzman '389, 9 Appeal2016-005232 Application 13/338,883 the duration of the mechanical agitation step in Sanderson, during which reaction between the microorganisms and the inorganic substrate occurs, would be routinely varied, depending the degree of hydrocarbon separation achieved or desired. Appellant's arguments do not, therefore, persuade us that the Examiner erred in finding that an ordinary artisan would have considered the duration of the mechanical agitation step of Sanderson's process to be a result-effective variable, and would therefore have considered obvious the determination of a suitable duration of that step, including the 12 hour duration recited in Appellant's claim 11. Appellant's arguments (App. Br. 20-26; Reply Br. 12-24) also do not persuade us that the Examiner failed to articulate clearly with adequate reasoning, and a rational underpinning, a motivation for combining Cuypers and Vrvic with Sanderson, nor are we persuaded that the combination posited by the Examiner would render Sanderson unsuitable for its intended purpose. As the Supreme Court has explained, "when a patent 'simply arranges old elements with each performing the same function it had been known to perform' and yields no more than one would expect from such an arrangement, the combination is obvious." KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 417 (2007). The Court also explained that, in determining whether the prior art supplied a reason for practicing the claimed subject matter, the analysis "need not seek out precise teachings directed to the specific subject matter of the challenged claim, for a court can take account of the inferences and creative steps that a person of ordinary skill in the art would employ." Id. at 418; see also id. at 421 ("A 10 Appeal2016-005232 Application 13/338,883 person of ordinary skill is ... a person of ordinary creativity, not an automaton."). In the instant case, as the Examiner found (Final Action 6-8), Sanderson describes a process that includes all of the basic steps of claim 11, including providing a microorganism-containing medium, providing oil shale, treating the oil shale with the medium, mechanically agitating the medium, and separating hydrocarbon-containing kerogen from the treated medium. Specifically, Sanderson discloses "treatment of shale with microorganisms capable of metabolizing certain hydrocarbons, sulfur- containing, and nitrogen-containing constituents thereof in the presence of a microbiological nutrient medium capable of supporting such metabolism, whereby the bulk of the kerogen is released and made available for recovery." Sanderson, 1:54--2: 1. In describing one example of its process, Sanderson explains that the "shale and medium are combined in proportions to form a slurry which can be agitated as by mechanical means to maintain the solid particles of the shale in suspension. This insures intimate and continued contact of the microorganisms with the shale particles." Id. at 3 :46-51. Although Sanderson differs from claim 11 in that the reference does not appear to use rotary tumbling as its mechanical agitation method, as the Examiner found (Final Action 8), Cuypers teaches that when using microorganisms to remove hydrocarbons from soil, i.e. bioremediating or biodegrading the soil, rotary tumbling is a suitable method of mechanically agitating the microorganism/soil mixture. Cuypers 464 ("[D]egradation potential was demonstrated during growth of the enrichment and during experiments in which the inoculum was added to sterilized contaminated 11 Appeal2016-005232 Application 13/338,883 soil. After inoculation bottles were capped and incubated at 30°C. Samples were mixed on a rotary tumbler at 22 rpm."). Given Cuypers' s teaching that rotary tumbling was a useful method of mechanically agitating a mixture of microorganisms and hydrocarbon-containing soil for the purpose of removing the hydrocarbons, we agree with the Examiner that an ordinary artisan would have reasonably inferred that technique would be also useful for mechanically agitating the microorganism/shale medium described in Sanderson. Although Sanderson differs from claim 11 also in that the reference does not appear to use centrifugation as its separation technique, as the Examiner found (Final Action 9), Vrvic teaches that, when using the microorganism Bacillus circulans to demineralize oil shale to yield kerogen, centrifugation is a suitable method of separating the bacterial biomass from the oil shale substrates. See Vrvic 1203 ("Demineralization of an oil shale by Bacillus circulans ('siliceous bacteria')" (article title); see also id. at 1207 ("The bacterial biomass was separated from the [oil shale] substrates by centrifugation. The substrates were then rinsed successively several times with warm distilled water (80°C), 10% aqueous solution of ammonia and warm distilled water again. The solid residues were finally separated by centrifugation and dried at 80°C."). Given Vrvic's teaching that centrifugation was a useful method of separating microorganisms and solid residues from microorganism-treated oil shale, we agree with the Examiner that an ordinary artisan would have reasonably inferred that centrifugation would be similarly useful in separating those components from the microorganism/shale medium described in Sanderson. 12 Appeal2016-005232 Application 13/338,883 Accordingly, for the reasons discussed, we are not persuaded that the Examiner failed to provide reasons, supported by rational underpinnings, for combining the teachings of Cuypers and Vrvic with Sanderson. Appellant contends that the Examiner failed to establish motivation for combining Cuypers and Vrvic with Sanderson because the Examiner did not explain specifically how an ordinary artisan could or would have modified the device shown in Sanderson's Figure 1 to accommodate Cuypers's rotary tumbler or Vrvic's centrifuge. App. Br. 20-22; Reply Br. 12-18, 21-22. Appellant contends further that modifying the device shown in Sanderson's Figure 1 to accommodate a rotary tumbler and centrifuge would have rendered Sanderson' device unfit for its intended use, and would have required a complete redesign of that device. App. Br. 22-26; Reply Br. 19-23. As the Examiner explained, however (Final Action 7, 8), Sanderson described the device shown in Figure 1 as merely "one example" of how its process could be performed (Sanderson, 3 :9), and later expressly stated that "[ o ]bviously, many modifications and variations of the invention as set forth above may be made without departing from the spirit and scope thereof, and therefore only such limitations should be imposed as are indicated in the appended claims" (id. 4:75-5:5). As the Examiner also noted, the claims of the Sanderson patent "do not require the use of the disclosed device." Final Action 7; see also Sanderson, 5:6-6: 10 (claims of Sanderson). Indeed, in the Final Action from which this appeal was taken, the Examiner repeatedly avers that the posited combination of references is not intended to demonstrate the obviousness of modifying the exemplified device shown in Sanderson's Figure 1. Final Action 8 ("Regarding carrying 13 Appeal2016-005232 Application 13/338,883 out the method of Sanderson without the disclosed device but employing a mechanical rotary tumbler to form the suspension and obtaining the hydrocarbons via centrifugation, it is again noted that the use of the mechanical device by Sanderson is simply one embodiment of the invention.")(emphasis added); id. at 10 ("[T]he disclosures by Vrvic and Cuypers reasonably inform the ordinary artisan that the method of Sanderson can be carried out by combining fine particles of oil shale with a bioremedium [sic] with agitation by a mechanical rotary tumbler in a plain vessel (as opposed to the device taught by Sanderson) followed by separation of the reaction mixture via centrifugation.")( emphasis added); id. at 43 ("[T]he rejection in no way states or suggests that the device of Sanderson could or should be modified with a rotary tumbler and/or centrifuge .... [T]he rejection makes clear that the Examiner is not proposing a modification of the device by somehow adding and/or modifying with a rotary tumbler and/or centrifuge."). Thus, we are persuaded that the Examiner's position was simply that, based on the cited references as discussed above, an ordinary artisan would have considered it obvious to perform the process taught in Sanderson using rotary tumbling to effect Sanderson's mechanical agitation step, and using centrifugation to effect Sanderson's separation, and not to somehow force-fit a rotary tumbler and centrifuge onto the device shown in Sanderson's Figure 1 and described at Sanderson's column 3. Accordingly, Appellant's arguments do not persuade us that the Examiner failed to explain adequately why an ordinary artisan would have been motivated to modify Sanderson's process by using rotary tumbling to effect Sanderson's mechanical agitation step, and centrifugation to effect Sanderson's separation. 14 Appeal2016-005232 Application 13/338,883 Moreover, Appellant's arguments about rendering Sanderson unfit for its intended purpose are essentially based entirely on asserted impossible modifications to the device shown in Sanderson's Figure 1, or a complete redesign of that specific device (App. Br. 22-26; Reply Br. 19-23), whereas, as discussed above, the Examiner's position was not that it would have been obvious to modify the device shown in Sanderson's Figure 1. Accordingly, Appellant's arguments do not persuade us that the Examiner's posited combination of references would have rendered Sanderson's process unsuitable for its intended purpose. In addition, given that the Examiner, as discussed above, repeatedly stated in the Final Action that the rejection was not positing a modification of Sanderson's exemplified device, Appellant's arguments (Reply Br. 23-24) do not persuade us that the Examiner was insufficiently clear in the Final Action, or that a substantially different position from that advanced in the Final Action was adopted in the Answer. Also, as to the prior decisions by this Board cited by Appellant, for the reasons discussed above, we find that the facts before us dictate that the Examiner's rejection is supported by a preponderance of the evidence of record. In sum, for the reasons discussed, Appellant's arguments do not persuade us that a preponderance of the evidence fails to support the Examiner's prima facie case as to claim 11. Because Appellant does not advance objective evidence of nonobviousness to rebut the Examiner's prima case, we affirm the Examiner's rejection of claim 11 over the cited references. 15 Appeal2016-005232 Application 13/338,883 OBVIOUSNESS-CLAIM 12 Claim 12 recites a process similar to that recited in claim 11, discussed above, except that claim 12 does not recite the presence of sugar, molasses, muriatic, and yeast in the oil shale-treating biomedium, nor does claim 12 specify that the rotary tumbling is performed for about 12 hours. See App. Br. 28. In rejecting claim 12 as obvious over Sanderson, McDaniel, Simpson, Cuypers, and Vrvic, the Examiner relied on the teachings of those references essentially for the same reasons discussed above. See Final Action 16-21. As to this rejection, Appellant argues only that "[i]ndependent claims 12-14 recite similar subject matter and are rejected for the same reasons. Hence, rejections of claims 12-14 must be reversed as well." App. Br. 26; see also Reply Br. 21, 23. For the reasons discussed above, we do not find Appellant's arguments persuasive and, accordingly, affirm the Examiner's obviousness rejection of claim 12. OBVIOUSNESS-CLAIM 13 Claim 13 recites a process similar to that recited in claim 11, discussed above, except that claim 13 does not specify that the rotary tumbling is performed for about 12 hours. See App. Br. 28-29. In rejecting claim 13 as obvious over Sanderson, McDaniel, Simpson, Ritzman '930, Goklen, and Vrvic, the Examiner relied on the teachings of those references essentially for the same reasons discussed above. See Final Action 21-28. As to this rejection, Appellant argues only that "[i]ndependent claims 12-14 recite similar subject matter and are rejected for the same reasons. Hence, rejections of claims 12-14 must be reversed as well." App. Br. 26; 16 Appeal2016-005232 Application 13/338,883 see also Reply Br. 21, 23. For the reasons discussed above, we do not find Appellant's arguments persuasive and, accordingly, affirm the Examiner's obviousness rejection of claim 13. OBVIOUSNESS-CLAIMS 13 AND 14 Claim 14 depends from claim 13, discussed above, and specifies that the rotary tumbling is performed for about 12 hours. See App. Br. 29. In rejecting claims 13 and 14 as obvious over Sanderson, McDaniel, Simpson, Ritzman '930, Goklen, Vrvic, Cuypers, and Ritzman '389, the Examiner relied on the teachings of those references essentially for the same reasons discussed above. See Final Action 29--30. As to this rejection, Appellant argues only that "[i]ndependent claims 12-14 recite similar subject matter and are rejected for the same reasons. Hence, rejections of claims 12-14 must be reversed as well." App. Br. 26; see also Reply Br. 21, 23. For the reasons discussed above, we do not find Appellant's arguments persuasive and, accordingly, affirm the Examiner's obviousness rejection of claims 13 and 14.
