SCHEINER, LORA M. GREEN, and FRANCISCO C. PRATS, Administrative Patent Judges. PRATS, Administrative Patent Judge. DECISION ON APPEAL This is an appeal under 35 U.S.C. § 134 involving claims to compositions that can be used as shampoos. The Examiner has rejected the claims as obvious. We have jurisdiction under 35 U.S.C. § 6(b). We affirm. Appeal 2008-5242 Application 10/262,700 STATEMENT OF THE CASE Claims 1-20 are pending and on appeal (App. Br. 5). Claims 1 and 10 are illustrative and read as follows: 1. A composition comprising: a) from about 5 to about 50 weight percent of a detersive surfactant, b) at least about 0.025 to 5 weight percent hollow particles having a mean particle size from about 1 micron to about 80 microns, and c) at least about 20 weight percent of an aqueous carrier. 10. The composition of claim 1 further comprising a cationic polymer. The Examiner cites the following documents as evidence of unpatentability: Roulier US 5,925,380 Jul. 20, 1999 Young US 6,113,890 Sep. 5, 2000 The following rejection is before us for review: Claims 1-20 stand rejected under 35 U.S.C. § 103(a) as being unpatentable over Roulier and Young (Ans. 3-4). OBVIOUSNESS Issue The Examiner finds that Roulier discloses topical compositions that contain the claimed hollow particles and surfactants, the compositions disclosed as being useful as shampoos (Ans. 3). The Examiner finds that the differences between Roulier and the claims are that Roulier “does not teach [the] higher amount of water and cationic polymer” (id.) (emphases removed). To meet those limitations, the Examiner cites Young as 2 Appeal 2008-5242 Application 10/262,700 disclosing shampoo compositions containing ingredients similar to those in Roulier, along with an aqueous carrier and cationic polymer (id.). The Examiner concludes that one of ordinary skill in the art would have considered it obvious to “prepare compositions of [Roulier] using the hollow particles, detersive surfactant and increase the water content and add cationic polymer taught by [Young] in analogous shampoo compositions using particles and surfactants” (id. at 4). The Examiner reasons that a person of ordinary skill would have been prompted “to add cationic polymer with the reasonable expectation of success that the cationic polymer enhances the deposition of hollow particles” (id.). The Examiner further reasons that “one of ordinary skill in the art would increase the water content with the reasonable expectation of success that the water helps in making the composition as pourable liquid, which is beneficial to the consumer” (id.). Appellants contend that the Examiner failed to make a prima facie case of obviousness because one of ordinary skill in the art would not have been prompted to modify Roulier’s essentially dry solid compositions to achieve a composition having the claimed ingredients in the claimed amounts (App. Br. 12-21). In view of the positions advanced by the Examiner and Appellants, the issue with respect to this rejection is whether the Examiner has made a prima facie case that the teachings of Roulier and Young would have rendered a composition having the claimed ingredients in the claimed amounts obvious to a person of ordinary skill in the art. Findings of Fact (“FF”) 1. Roulier discloses “dosage forms for cosmetic or dermatological use, in the form of an expanded solid composition whose matrix comprises of a 3 Appeal 2008-5242 Application 10/262,700 cellular network formed from a starch-rich product and contains expanded thermoplastic hollow particles of homopolymer or copolymer of an ethylenically unsaturated monomer or mixture of such monomers” (Roulier, col. 1, ll. 17-23). 2. Roulier discloses that “preferably, the particles . . . are hollow particles of an expanded copolymer of vinylidene chloride and acrylonitrile, or of vinylidene chloride, acrylonitrile and methyl methacrylate. These particles may be dry or hydrated” (Roulier, col. 3, ll. 11-15). 3. Roulier discloses that “[t]he expanded thermoplastic hollow particles are present in the compositions of the invention in concentrations preferably ranging from 2 to 30% by weight relative to the total weight of the composition” (Roulier, col. 3, ll. 36-39). 4. Roulier discloses that “[t]he compositions according to the invention possess a water content preferably not exceeding 5% by weight, and more preferably ranging from 1 to 2% by weight, relative to the weight of the composition” (Roulier, col. 3, ll. 60-63). 5. Roulier discloses that its solid compositions may be “expanded cylinders, pellets, leaves or flakes applied directly to the skin or the face, or be reduced to powder and used as such, in a traditional manner, as make-up powder,” and can also “take the form of powder for care and/or hygiene, applied directly to the skin, scalp or hair, for example dry shampoos or loose powders for body care” (Roulier, col. 2, ll. 19-24). 6. Roulier discloses that the expanded cylinders, pellets, leaves, or flakes may be “stored in the dry state, and be very readily amenable to rehydration after immersion in an aqueous medium to reconstitute formulations for make-up such as make-up foundations or formulations for care or hygiene 4 Appeal 2008-5242 Application 10/262,700 such as creams, milks, foam baths, gels and shampoos” (Roulier, col. 2, ll. 26-31). 7. Roulier discloses that the dry-stored compositions can, “at the time of use, [be] rehydrated after immersion in water to reconstitute a liquid or semi- liquid aqueous make-up formulation such as a make-up foundation” (Roulier, col. 5, l. 67, though col. 6, l. 2). 8. Roulier discloses: The compositions according to the invention can be products for the care and/or hygiene of the skin, mucosae, scalp or hair. They may take the form of powder and be applied directly to the skin, scalp or hair as for example, a dry shampoo or a loose powder for body care. These compositions may also take the form of powder or alternatively of expanded cylinders, pellets or flakes which are amenable to rehydration after immersion in water so as to reconstitute an aqueous formulation for care and/or hygiene, such as a cream, milk, gel, foam bath or shampoo. (Roulier, col. 6, ll. 3-12.) 9. Example 1 of Roulier discloses a “[d]ry shampoo in the form of a powder to be rehydrated” (Roulier, col. 6, l. 19). The shampoo of Roulier’s Example 1 has, by weight, 35% wheat flour, 35% maize starch, 15% expanded particles of vinylidene chloride/acrylonitrile/methyl methacrylate copolymer, and 15% sodium lauryl ether sulphate, a surfactant (id. at col. 6. ll. 22-28). 10. Roulier discloses that its compositions can contain “inorganic or organic fillers customarily used in make-up products, . . . [as well as] metal soaps derived from C8 -C22 carboxylic acid. They are present in 5 Appeal 2008-5242 Application 10/262,700 concentrations preferably ranging from 0 to 50% by weight relative to the weight of the composition” (Roulier, col. 4, ll. 59-67). 11. Young discloses “hair shampoo compositions which provide cleaning and styling performance, and which contain latex polymer particles, water- soluble cationic polymer as a latex deposition aid, organic oil as a latex deposition aid, and typically one or more surfactants, an aqueous carrier and one or more optional ingredients” (Young, abstract). 12. Young discloses that its shampoo compositions “are typically in the form of pourable liquids (under ambient conditions). The shampoo compositions will therefore typically comprise an aqueous carrier, which is present at a level of from about 20% to about 95%, preferably from about 60% to about 85%, by weight of the shampoo compositions” (Young, col. 11, ll. 11-16). 13. Young discloses that the latex particles in its compositions are present in amounts “up to about 25%, preferably from about 0.05% to about 25%, more preferably from 0.05% to about 15%, more preferably from about . . . 0.1% to about 10%, and most preferably from about 0.5% to about 7%, by weight” (Young, col. 11, ll. 28-32). 14. Young discloses that the latex particles in its compositions are polymers made from monomers including “styrene, butadiene, ethylene, acrylonitrile, chloroprene, vinylidene chloride, isoprene, isobutylene and vinyl chloride, and esters of acrylic, methacrylic, vinylacetic, maleic, crotonic and itaconic acids,” and that those monomers “may be mixed with one or more ionic monomers, e.g., acrylic acid, methacrylic acid, to form charged latex polymer systems” (Young, col. 11, ll. 59-65). 6 Appeal 2008-5242 Application 10/262,700 15. Young discloses that “[s]ynthetic surfactants for use in the shampoo compositions . . . will generally be present at a level from about 0.5% to about 50%, more typically from about 4% to about 30%, more typically from about 5% to about 25%, by weight, of the shampoo composition” (Young, col. 2, ll. 39-44). Young notes, however, that “[t]otal surfactant concentrations in the shampoo compositions can vary depending on the shampoo base formulation, the selected surfactant, cosurfactants, product results desired and so forth” (id. at col. 2, ll. 44-48). 16. Young discloses that that cationic polymer is present in its shampoo compositions at “concentrations effective to enhance deposition of the latex polymer particles . . . . Such concentrations will typically be from about 0.01% to about 5%, preferably from about 0.05% to about 3%, more preferably from about 0.1% to about 2%, by weight of the shampoo compositions” (Young, col. 6, ll. 54-59). Principles of Law Addressing the question of obviousness in KSR Int' l Co. v. Teleflex Inc., 127 S. Ct. 1727 (2007), the Supreme Court reaffirmed that under the controlling inquiry, “the scope and content of the prior art are to be determined; differences between the prior art and the claims at issue are to be ascertained; and the level of ordinary skill in the pertinent art resolved.” Id. at 1734 (quoting Graham v. John Deere Co. of Kansas City, 383 U.S. 1, 17-18 (1966)). In proceedings before the Patent and Trademark Office, the Examiner bears the burden of establishing a prima facie case of obviousness based upon the prior art. “[The Examiner] can satisfy this burden only by showing some objective 7 Appeal 2008-5242 Application 10/262,700 teaching in the prior art or that knowledge generally available to one of ordinary skill in the art would lead that individual to combine the relevant teachings of the references.” In re Fritch, 972 F.2d 1260, 1265 (Fed. Cir. 1992) (citations omitted, bracketed material in original). Thus, as the Supreme Court pointed out in KSR, “a patent composed of several elements is not proved obvious merely by demonstrating that each of its elements was, independently, known in the prior art.” KSR, 127 S. Ct. at 1741. Rather, as the Court stated: [I]t can be important to identify a reason that would have prompted a person of ordinary skill in the relevant field to combine the elements in the way the claimed new invention does . . . because inventions in most, if not all, instances rely upon building blocks long since uncovered, and claimed discoveries almost of necessity will be combinations of what, in some sense, is already known. Id. (emphasis added); see also id. at 1740-41 (requiring a determination of “whether there was an apparent reason to combine the known elements in the fashion claimed by the patent at issue”) (emphasis added). While holding that some rationale must be supplied for a conclusion of obviousness, the Court nonetheless rejected a “rigid approach” to the obviousness question, and instead emphasized that “[t]hroughout this Court's engagement with the question of obviousness, our cases have set forth an expansive and flexible approach . . . .” Id. at 1739. The Court also rejected the use of “rigid and mandatory formulas” as being “incompatible with our precedents.” Id. at 1741; see also 1742-43 (“Rigid preventative rules that deny factfinders recourse to common sense, however, are neither necessary under our case law nor consistent with it.”). 8 Appeal 2008-5242 Application 10/262,700 The Court thus reasoned that the analysis under 35 U.S.C. § 103 “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 1741. The Court further advised that “[a] person of ordinary skill is . . . a person of ordinary creativity, not an automaton.” Id. at 1742. Regarding hindsight reasoning, the Court stated that “[a] factfinder should be aware, of course, of the distortion caused by hindsight bias and must be cautious of arguments reliant upon ex post reasoning. Rigid preventative rules that deny factfinders recourse to common sense, however, are neither necessary under our case law nor consistent with it.” Id. at 1742- 1743 (citations omitted). When evaluating claims for obviousness, “the prior art as a whole must be considered. The teachings are to be viewed as they would have been viewed by one of ordinary skill.” In re Hedges, 783 F.2d 1038, 1041 (Fed. Cir. 1986). Accordingly, “‘[i]t is impermissible within the framework of section 103 to pick and choose from any one reference only so much of it as will support a given position, to the exclusion of other parts necessary to the full appreciation of what such reference fairly suggests to one of ordinary skill in the art.’” Id. (quoting In re Wesslau, 353 F.2d 238, 241 (CCPA 1965)). Thus, “in a section 103 inquiry, ‘the fact that a specific [embodiment] is taught to be preferred is not controlling, since all disclosures of the prior art, including unpreferred embodiments, must be considered.’” Merck & Co. Inc. v. Biocraft Laboratories Inc., 874 F.2d 804, 807 (Fed. Cir. 1989) (quoting In re Lamberti, 545 F.2d 747, 750 (CCPA 1976)); see also In re 9 Appeal 2008-5242 Application 10/262,700 Mills, 470 F.2d 649, 651 (CCPA 1972) (“All the disclosures in a reference must be evaluated, including nonpreferred embodiments, and a reference is not limited to the disclosure of specific working examples.” (citations omitted)). Moreover, as often stated, “[n]on-obviousness cannot be established by attacking references individually where the rejection is based upon the teachings of a combination of references. . . . [The reference] must be read, not in isolation, but for what it fairly teaches in combination with the prior art as a whole.” In re Merck & Co., Inc., 800 F.2d 1091, 1097 (Fed. Cir. 1986). The test of obviousness, therefore, is “whether the teachings of the prior art, taken as a whole, would have made obvious the claimed invention.” In re Gorman, 933 F.2d 982, 986 (Fed. Cir. 1991). Analysis The claims have not been argued separately and therefore stand or fall together. 37 C.F.R. § 41.37(c)(1)(vii). We select claim 1 as representative of the rejected claims. Id. Appellants’ arguments do not persuade us that the Examiner failed to make a prima facie case that a composition having the ingredients recited in claim 1, in the amounts recited in claim 1, would have been obvious to a person of ordinary skill in the art. Appellants argue: [Roulier’s] disclosure, directed entirely to solid formulations, provides no apparent reason for one of skill in the art to modify the teachings therein to (a) eliminate the starch- rich product, and (b) the resulting starch-based matrix, and provide an aqueous composition (c) containing at least 20% 10 Appeal 2008-5242 Application 10/262,700 aqueous carrier, or (d) reduce the amount of hollow particles to a maximum of 5%, let alone make all four modifications. (App. Br. 15-16, 20.) This argument does not convince us that the Examiner erred. We note that the main thrust of Roulier’s disclosure is the preparation of dry solid formulations (see FF 1, 4, 5). However, rather than being exclusively directed to dry solid formulations, Roulier explicitly discloses that its dry compositions are “very readily amenable to rehydration after immersion in an aqueous medium to reconstitute . . . formulations for care or hygiene such as creams, milks, foam baths, gels and shampoos” (Roulier, col. 2, ll. 26-31 (FF 6; see also FF 7, 8)). Thus, in Example 1, Roulier describes the composition as a “[d]ry shampoo in the form of a powder to be rehydrated” (Roulier, col. 6, l. 19 (FF 9) (emphasis added)). We therefore agree with the Examiner that, rather than describing only dry compositions, Roulier discloses that it was desirable to prepare compositions that contain an aqueous carrier in addition to the other ingredients recited in claim 1. We therefore also agree with the Examiner that Roulier would have provided a person of ordinary skill impetus to add an aqueous carrier to the dry shampoo compositions. Moreover, one of ordinary skill in the art, being a person of ordinary creativity and common sense, see KSR, 127 S. Ct at 1742-43, would have reasoned that adding an aqueous carrier to Roulier’s dry compositions in the manner directed in the reference would have resulted in reduced concentrations of the ingredients present in the dried compositions. We 11 Appeal 2008-5242 Application 10/262,700 therefore do not agree with Appellants that Roulier fails to provide a suggestion of reducing the amount of hollow particles. As to the elimination of the starch-based ingredients in Roulier’s compositions, we do not see where the Examiner’s rejection posits such a change. However, as noted above, one of ordinary skill would have reasoned that adding an aqueous carrier as directed by Roulier would reduce the amount of that ingredient in the resulting liquid formulation. Nonetheless, claim 1 encompasses the presence of the Roulier’s starch ingredients. See Genentech, Inc. v. Chiron Corp., 112 F.3d 495, 501 (Fed. Cir. 1997) (“‘Comprising’ is a term of art used in claim language which means that the named elements are essential, but other elements may be added and still form a construct within the scope of the claim.”). Appellants’ arguments regarding the deficiencies of Roulier viewed alone also fail to take account of the teachings of Young. It is well settled that non-obviousness cannot be shown by arguments directed to a single reference when the rejection at issue combines disclosures from a plurality of prior art documents. See In re Merck, 800 F. 2d at 1097. Thus, as the Examiner points out, Young teaches that, in liquid latex particle-containing shampoo compositions, an aqueous carrier is desirably present in amounts from 20% to about 95% by weight (FF 12). A person of ordinary skill in the art rehydrating Roulier’s compositions as directed by Roulier would therefore have reasonably inferred that from 20% to about 95% by weight of an aqueous carrier would be a suitable rehydrating amount. Given the combined teachings of the cited references, we agree with the Examiner that one of ordinary skill in the art would have considered 12 Appeal 2008-5242 Application 10/262,700 it obvious to rehydrate Roulier’s compositions with an aqueous carrier at a concentration of “at least about 20 weight percent,” as recited in claim 1. Appellants argue that Roulier fails to supports the Examiner’s prima facie case because “[t]he only specific disclosure relating to an amount of hollow particles in a shampoo composition is in the examples. In particular, Example 1 of [Roulier] incorporates 15%, by weight, hollow particles, which is three times greater than the maximum amount of hollow particles recited in the present claims” (App. Br. 16). Thus, Appellants argue, although Roulier “broadly discloses compositions comprising 2-30% by weight hollow particles, because [of] the breadth of the type of compositions disclosed in the reference, the only true teaching in [Roulier] for shampoo- like compositions is found in Example 1, which uses three times the maximum amount of the present claims” (id. at 16-17). We are not persuaded by these arguments. It is well settled that an obviousness evaluation is not limited to the references’ examples or preferred embodiments, but includes all relevant teachings. See Merck v. Biocraft, 874 F.2d at 807; In re Mills, 470 F.2d at 651. Appellants’ claim 1 requires the composition to contain “at least about 0.025 to 5 weight percent hollow particles.” As Appellants acknowledge, Roulier discloses that its dry solid compositions can contain from 2% to 30% by weight of the hollow particles (FF 3), a range that overlaps with claim 1. Following Roulier’s teachings, and hydrating the dried shampoo compositions with an aqueous carrier in an amount of 20% to 95% as taught by Young, would result in a proportional dilution of the original dry ingredients, including the hollow particles, in the aqueous carrier. Given the 13 Appeal 2008-5242 Application 10/262,700 concentrations of hollow particles disclosed by Roulier as being suitable in the initial dry compositions, and the amounts of aqueous carrier disclosed by Young as being suitable, hydrating Roulier’s dry compositions would result in compositions having a hollow particles in a range of concentrations that overlaps the range recited in claim 1. We therefore agree with the Examiner that one of ordinary skill in the art would have reasonably inferred that the concentration of hollow particles recited in claim 1 would be desirable in a liquid composition containing the claimed amount of an aqueous carrier. Moreover, Young discloses that its latex particles are made from many of the same monomers as Roulier’s hollow latex particles (compare FF 2 and 14), and are suitably present in a shampoo at a concentration most preferably of about 0.5% to about 7% (FF 13). A preponderance of the evidence therefore supports the Examiner’s conclusion that one of ordinary skill in the art would have considered it obvious for a liquid shampoo composition rehydrated from Roulier’s dry formulations to have at least about 0.025% to 5% of Roulier’s hollow particles, as recited in claim 1. Appellants argue that the disclosure spanning columns 5 and 6 of Roulier fails to teach or suggest adding an aqueous carrier to Roulier’s dry solid compositions (App. Br. 17). Rather, Appellants argue, Roulier “provides no teachings of liquid products, such as any undisclosed compositions that may possibly be prepared after rehydration, or that such liquid products can be successfully made using the starch product-rich matrix of [Roulier’s] composition with any reasonable expectation of providing a useful or stable hair shampoo- conditioning composition” (id.). We do not agree. As noted above, an obviousness evaluation is not limited to the references’ examples or preferred embodiments, but includes 14 Appeal 2008-5242 Application 10/262,700 all relevant teachings. See Merck v. Biocraft, 874 F.2d at 807; In re Mills, 470 F.2d at 651. As also noted above, it is improper to base an obviousness analysis only on portions of a reference that support a particular position, while ignoring other portions crucial to a complete understanding of how a person of ordinary skill in the art would view the reference. In re Hedges, 783 F.2d at 1041. As discussed above, while the main thrust of Roulier’s disclosure is the preparation of dry solid formulations (see FF 1, 4, 5), Roulier explicitly discloses that its dry compositions are “very readily amenable to rehydration after immersion in an aqueous medium to reconstitute . . . formulations for care or hygiene such as creams, milks, foam baths, gels and shampoos” (Roulier, col. 2, ll. 26-31 (FF 6; see also FF 7, 8)). Thus, in Example 1, Roulier goes so far as to explicitly describe the intended use of the exemplified composition as a “[d]ry shampoo in the form of a powder to be rehydrated” (Roulier, col. 6, l. 19 (FF 9) (emphasis added)). Appellants’ arguments therefore do not persuade us that Roulier would have failed to prompt one of ordinary skill in the art to add an aqueous carrier to the dried compositions as claimed. Appellants argue that “[Young] fails to overcome the deficiencies of [Roulier]” (App. Br. 18). Specifically, Appellants argue that the Examiner has no basis for finding that one of ordinary skill in the art would have had a reasonable expectation that Young’s cationic polymers would enhance the deposition of Roulier’s hollow particles (id.). Moreover, Appellants argue, while dependent claims 10-12 and 14-16 recite compositions that contain cationic polymers, those claims merely recite preferred embodiments, whereas “Appellants do not rely upon the 15 Appeal 2008-5242 Application 10/262,700 presence of a cationic polymer as the sole basis of patentability, but rather rely upon the presence of a cationic polymer and all of the features recited in the independent claims from which these claims depend for patentability (id. at 19). Appellants’ arguments do not persuade us that the Examiner erred in combining Roulier and Young. Young discloses that its cationic polymer acts to enhance the deposition of the latex particles in its compositions (see FF 11, 16). As the Examiner points out, Young’s latex particles are polymers which can be made from monomers including acrylonitrile, vinylidene chloride, and methacrylic acid and its esters (FF 14), whereas Roulier’s hollow particles are preferably made from “an expanded copolymer of vinylidene chloride and acrylonitrile, or of vinylidene chloride, acrylonitrile and methyl methacrylate” (Roulier, col. 3, ll. 11-15 (FF 2)). Because Young discloses that its cationic polymer acts to enhance deposition of latex polymers made from acrylonitrile, vinylidene chloride, methacrylic acid and its esters, and because Roulier discloses that its hollow particles are made of the same materials, we agree with the Examiner that a person of ordinary skill would have had a reasonable expectation that Young’s cationic polymers would enhance the deposition of Roulier’s hollow particles. Moreover, because both references are directed to shampoo compositions having polymeric latex particles made of the same materials, we also agree with the Examiner that a person of ordinary skill would have been prompted to look to Young when determining how much aqueous carrier would be suitable for rehydrating Roulier’s dry compositions. 16 Appeal 2008-5242 Application 10/262,700 Appellants argue that, in contrast to Roulier’s use of high percentages of hollow particles, it is their “discovery that an aqueous composition having a low amount of hollow particles achieves several advantages, including better texture to the hair fiber surface and enhanced inter hair fiber friction. . . . This enhanced friction allows for reduced slippage and helps increase body and volume of the hair” (App. Br. 18 (citing Specification 36:25-28)). Appellants urge that compositions with the claimed low amount of hollow particles “impart increased hair volume and body, bounce, fullness, springiness, and texture to the hair (id. at 19 (citing Specification 36:20 through 37:3)). We are not persuaded by these arguments. As discussed above, Roulier discloses that the hollow particles are useful in a range of concentrations that overlap the claimed concentration range, even when the Roulier’s compositions are hydrated with an aqueous carrier. Moreover, as also discussed above, Young discloses that its latex particles are made from the same materials as Roulier’s hollow latex particles (compare FF 2 and 14), and are suitably present in a shampoo at a concentration most preferably of about 0.5% to about 7% (FF 13). We therefore do not agree with Appellants that the claimed range of hollow particles is lower than that suggested by the prior art. Also, while Appellants appear to suggest that the properties imparted to hair by the disclosed compositions can be considered unexpected, Appellants point to no direct comparison between the claimed compositions and the closest prior art to support that suggestion. See In re Baxter- Travenol Labs., 952 F.2d 388, 392 (Fed. Cir. 1991) (“[W]hen unexpected 17 Appeal 2008-5242 Application 10/262,700 results are used as evidence of nonobviousness, the results must be shown to be unexpected compared with the closest prior art.”) In sum, Appellants’ arguments do not persuade us that the Examiner erred in concluding that the composition of claim 1 would have been prima facie obvious to a person of ordinary skill in the art viewing Roulier and Young. We therefore affirm the Examiner’s rejection of claim 1 as obvious over those references. Because they were not argued separately, claims 2-20 fall with claim 1. See 37 C.F.R. § 41.37(c)(1)(vii). No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a).
