DISCUSSION Background The claimed invention is directed to cosmetic compositions containing dispersions of polymer particles. Spec. ^ 2. The Specification states that it was known in the art to use polymer particle dispersions in cosmetics, but that such dispersions required large amounts of stabilizing polymers “in order to obtain a relatively stable dispersion of said particles.” Id. 3—4. “Thus,” the Specification continues, “the inventor has discovered, surprisingly, novel polymer particle dispersions which may afford good cosmetic properties . . . , and moreover, which do not comprise any stabilizer . . . Id. ^8. The cosmetic composition comprises at least one block copolymer in a liquid carbon-based medium. Id. ^f 9. The block copolymer, in turn, is made up of at least two blocks: a “first” block that is soluble in the medium, and a “second” block that is insoluble in the medium. Id. The Specification explains that “the physicochemical properties of the dispersion” can be modified by “appropriately selecting the monomers and the organic medium of which it is composed.” Id. ^ 10. The resulting 5 Appeal 2017-006257 Application 11/347,251 dispersion “has great affinity for the oily media usually used in cosmetics” and lacks “any tacky nature.” Id. The Examiner rejected representative claim 1 for obviousness over Blin in view of De La Poterie. Final Act. 3-6. The Examiner relied on Blin to teach the elements of claim 1, including a cosmetic composition comprising an organic (i.e., carbon-based) liquid medium and a block copolymer. Id. at 4 (citing Blin]fl| 1, 52, 53, 75-78, 88, 119, 446). The Examiner acknowledged that Blin does “not exemplify an embodiment of the claimed copolymers” and does “not teach the exact amount of first and second block polymers as instantly claimed.” Id. at 6. As to the amounts of first and second block polymers, the Examiner reasoned: [I]t would have been obvious to optimize or adjust the amount ranges of first and second block polymers with the claimed ranges without undue experimentation because Blin et al. teaches 10/90 to 90/10 ratio of first and second block polymers and the first and second block polymers exist in an amount of 20-90% and 5-75%, respectively, which overlap the claimed range of 10- 25% and 75-90%, respectively. . . . Unless the criticality of the ranges is given, the claimed ranges would be optimized from the teachings of Blin et al. Id. at 6-7 (citing In re Wertheim, 541 F.2d 257 (CCPA 1976)). And, as to the claimed copolymers, the Examiner relied on De La Poterie. Specifically, the Examiner found that De La Poterie “teaches a cosmetic composition containing at least one hydrophobic film-forming polymer and at least one thermal transition agent, in a physiologically acceptable medium” where the “hydrophobic film-forming polymer is present in the form of surface- stabilized particles dispersed in a liquid fatty phase.” Id. at 5 (citing De La Poterie, Abstract, 8, claims 1 & 18). The Examiner reasoned: 6 Appeal 2017-006257 Application 11/347,251 It would have been prima facie obvious to one of ordinary skill in the art at the time the claimed invention was made to modify a cosmetic composition of Blin et al. with the hydrophobic particles dispersed in the liquid fatty phase as taught by De La Poterie et al. and produce the instant invention. One of ordinary artisan would have been motivated to do so because the film forming polymer particle dispersion would have provided adhesion and ease coating on the keratinous material support according to the final use and easy removal after use as well. Id. at 7. The Examiner also rejected claim 21 for obviousness over Blin in view of De La Poterie, and further in view of Fukuoka. Final Act. 7-10. Claim 21 limits claim 1 by reciting specific polyolefins with a (meth)acrylate end group as the “at least one first block that is soluble in said liquid carbon-based medium.” See Br. 20 (claim 21). The Examiner found that Fukuoka teaches “using a macromonomer of a polyolefin (e.g., repeating ethylene-butylene or repeating propylene) with an unsaturated double bond functional group (e.g., vinyl, (meth)acryloyl, or allyl) at its terminus.” Final Act. 9 (citing Fukuoka, 5:19-30). The Examiner also found that Fukuoka teaches that olefmic macromonomers impart desirable characteristics such as adhesive properties, heat- and weather-resistance, low-temperature tackiness, well-balanced removability, and non-staining properties. Id. (citing Fukuoka, 6:36-44, 16:59-17:14). The Examiner reasoned: It would have been prima facie obvious to one of ordinary skill in the art at the time the claimed invention was made to include the polyolefin macromonomer of Fukuoka et al. in the polymeric dispersion of Blin et al. and produce the instant invention. The skilled artisan would have been motivated to include the 7 Appeal 2017-006257 Application 11/347,251 polyolefin macromonomer because Fukuoka et al. specifically teaches forming (meth)acrylate-backboned polymers that include such macromonomers to impart adhesion to the overall polymer based upon this teaching .... Id. Analysis On appeal, the Board “reviews the obviousness rejection for error based upon the issues identified by appellant, and in light of the arguments and evidence produced thereon.” Ex parte Frye, 94 USPQ2d 1072, 1075 (BPAI 2010) (precedential). Upon review of the record, we find no reversible error in the Examiner’s findings and conclusions, and thus affirm the Examiner’s rejection of claims 1-10, 20-23, 26^43, 45, and 46. Claim 1 Appellant first argues that “Blin does not teach the block polymer and as such the entire supposition of the rejection is improper.” Br. 9. Specifically, Appellant argues that “Blin already teaches that the block copolymers are to be used in solution not in a dispersion and so modifying Blin with De La Poterie is an error.” Id. Thus, Appellant’s argument appears to be that the Examiner erred because Blin’s block copolymers are prepared in solution, rather than in a dispersion. See id. (citing Blin 230- 37). As an initial matter, we agree with the Examiner that Blin teaches a block copolymer comprising a first soluble block and a second insoluble block. See Ans. 3. Specifically, Blin teaches a cosmetic composition comprising “at least 2 distinct blocks.” Blin 20, 42. Blin further teaches that, in one embodiment, the first block and the second block “are incompatible in the organic liquid medium.” Id. ^| 51. As the Examiner 8 Appeal 2017-006257 Application 11/347,251 explained, this means that the mixture formed from the first block and the second block is not miscible in the organic liquid. Id. 52; Ans. 3. Moreover, Blin exemplifies a first block (having a Tg of greater than or equal to 40°C) as preferably made of methyl acrylate, which—as the Examiner explained and Appellant does not dispute—is insoluble in the organic (carbon-based) liquid medium. Blin 88; Ans. 3 (citing Spec. 55-56). Blin also exemplifies a second block (having a Tg of between 20 and 40°C) as preferably made of 2-ethylhexyl acrylate, which is soluble in the organic liquid medium. Blin ^ 119; Ans. 3 (citing Spec. 47^18). Again, Appellant does not dispute the Examiner’s finding in this regard. We therefore disagree with Appellant that “Blin does not teach the block polymer.” Br. 9. Appellant argues that “Blin already teaches that the block copolymers are to be used in solution not in a dispersion.” Id. (citing Blin 191, 199, 207). In the Examples, Blin describes the preparation of certain polymers in “a solution containing 50% polymer active substance in isododecane.” See Blin ^ 186-193 (Example 1), 194-201 (Example 2), 202-209 (Example 3). Appellant does not, however, persuasively rebut the Examiner’s determination that in the chemical arts, a “dispersion” encompasses a “solution.” Ans. 4. As the Examiner explained, a dispersion is a mixture of substances in the form of a suspension, colloid, or solution. Id. \ see also Final Act. 8. Appellant’s citations to Wikipedia do not rebut the Examiner’s reasoned analysis. See Br. 9 (citing https://en.wikipedia.org/ wiki/Solution and https://en.wikipedia.org/wiki/Dispersion_(chemistry)). For example, the Internet page at https://en.wikipedia.org/wiki/Solution 9 Appeal 2017-006257 Application 11/347,251 states that a solution contains particles of a solute.5 And the Internet page at https://en.wikipedia.org/wiki/Dispersion_(chemistry) expressly states that there are three main types of dispersions: coarse dispersion (or suspension), colloid, and solution.6 Thus, Appellant’s allegation that there is a patentable distinction between Blin’s “solution” and the instantly-claimed “dispersion” is not persuasive. But even assuming that Blin’s block copolymers are initially produced in a solution (and that a solution is different from a dispersion), Blin nevertheless teaches a final cosmetic composition comprising a dispersion of polymer particles, as claimed. Specifically, Blin teaches that “[t]he composition according to the invention may be in the form in particular of a . . . dispersion.” Blin ^ 446. Appellant points us to nothing in the Specification evidencing that the claimed cosmetic composition containing a “dispersion” may not first be made in the form of a “solution.” See generally Br. The Specification, in fact, contemplates the opposite: that the first and second blocks of the block copolymer are initially synthesized in solution. See Spec. ^ 76 (“If the first block, referred to as the soluble block, is synthesized in bulk, the ‘insoluble’ block may then be synthesized in bulk or in solution.'''’ (emphasis added)); id. 78 (“If all the blocks are synthesized in solution, in a common solvent, the subsequent addition of a carbon-based solvent. . . will lead to the disclosed dispersion in the carbon-based media.” (emphasis added)). Thus, we are unpersuaded of reversible error in the s://en.wikipedia.org/wiki/Solution (last visited Feb. 8, 2018). s://en.wikipedia.org/wiki/Dispersionj chemistry) (last visited Feb. 8, 2018). 10 Appeal 2017-006257 Application 11/347,251 Examiner’s finding that Blin’s final cosmetic composition is in the form of a dispersion. Final Act. 4. Finally, even assuming that Blin’s block copolymers are not in the form of a dispersion, we are unpersuaded of reversible error in the Examiner’s determination that an ordinarily skilled artisan would have had a reason to combine De Fa Poterie with Blin to produce a cosmetic composition comprising a dispersion of polymer particles. Final Act. 7. Specifically, a preponderance of the evidence supports the Examiner’s finding that an ordinarily skilled artisan would have been motivated to modify Blin’s cosmetic composition with the hydrophobic particles dispersed in the liquid fatty phase as taught by De Fa Poterie. Id.', see also De Fa Poterie, claim 18. Blin teaches that cosmetic compositions should have “good texture” and “good staying powder on the lips,” Blin If 19, and De Fa Poterie teaches that the use of a film-forming polymer promotes adherence to keratinous materials, De Fa Poterie If 34. Thus, we agree with the Examiner that “there is reasonably sufficient motivation to combine these two references.” Ans. 6. Appellant argues that the addition of De Fa Poterie “ignore[s] the teachings of Blin that teach the exact opposite.” Br. 12. Appellant argues that the “proposed modification or combination of the prior art would change the principle of operation of the prior art” and therefore is improper. Id. But Appellant’s argument is conclusory and unsupported by evidence. For example, as explained above, both Blin and the Specification describe initially producing the block polymers in solution. Blin 186-193 (Example 1), Iffl 194-201 (Example 2), 202-209 (Example 3); Spec, inf 76, 78. And both Blin and the Specification describe the final cosmetic 11 Appeal 2017-006257 Application 11/347,251 composition as in the form of a dispersion. Blin 446; Spec. ^ 108. Appellant provides no persuasive explanation as to how the combination of De La Poterie changes the principle of operation of Blin. Thus, we find Appellant’s argument unpersuasive. Claims 2—10, 20, 22, 23, 26—43, 45, and 46 As to dependent claims 2-10, 20, 22, 23, 26^43, 45, and 46, Appellant only states that “[t]his error thus permeates the rejection of each of’ these claims. Because this statement does not amount to a separate argument, claims 2-10, 20, 22, 23, 26^43, 45, and 46 fall with claim 1. 37 C.F.R. § 41.37(c)(l)(iv). Claim 21 For claim 21, Appellant appears to argue that the Examiner relied on an improper “lead compound” analysis for combining the teachings of Fukuoka with Blin and De La Poterie. Br. 13-14. We disagree that the Examiner relied on a “lead compound” analysis. The Federal Circuit has explained that “[ojbviousness based on structural similarity . . . can be proved by identification of some motivation that would have led one of ordinary skill in the art to select and then modify a known compound (i.e. a lead compound) in a particular way to achieve the claimed compound.” Eisai Co. v. Dr. Reddy’s Labs., Ltd., 533 F.3d 1353, 1357 (Fed. Cir. 2008); see also Genetics Inst., LLC v. Novartis Vaccines & Diagnostics, Inc., 655 F.3d 1291, 1304 (Fed. Cir. 2011) (stating that the obviousness inquiry requires “the identification of some reason that would have prompted a researcher to modify the prior art compounds in a particular manner to arrive at the claimed compounds”). For example, close structural similarity between chemical compounds, such as homologs, may provide the requisite 12 Appeal 2017-006257 Application 11/347,251 reason or motivation. In re Dillon, 919 F.2d 688, 693 (Fed. Cir. 1990) (en banc). The motivation to modify the lead compound must be grounded in the ordinarily skilled artisan’s expectation that, given the close structural similarity, the claimed compounds will have the same properties as the prior-art compounds. Id.1 Here, the Examiner clearly did not rely on a “lead compound” analysis in rejecting claim 21. Claim 21 recites specific polyolefins with a (meth)acrylate end group as the “at least one first block that is soluble in said liquid carbon-based medium.” See Br. 20 (claim 21). The Examiner found that Fukuoka teaches “using a macromonomer of a polyolefin (e.g., repeating ethylene-butylene or repeating propylene) with an unsaturated double bond functional group (e.g., vinyl, (meth)acryloyl, or allyl) at its terminus.” Final Act. 9 (citing Fukuoka 5:19-30). The Examiner also found that Fukuoka specifically discloses the polyolefin macromonomer Kraton liquid polymer L-1253, which is a poly(ethylene/butylene) methacrylate macromonomer, that falls within the scope of claim 21. Ans. 8; Fukuoka 5:35-38. Appellant does not address Fukuoka’s teachings or dispute that Kraton liquid polymer L-1253 falls within the scope of claim 21. Thus, we 7 In any event, an obviousness analysis is an “expansive and flexible” inquiry. KSRInt’l Co. v. Teleflex Inc., 550 U.S. 398, 415 (2007). The inquiry may sometimes proceed by identifying a lead compound or reference composition, but not always. See Unigene Labs., Inc. v. Apotex, Inc., 655 F.3d 1352, 1360 (Fed. Cir. 2011) (“A prima facie case of obviousness in the chemical arts is often based on a known compound, called a ‘lead compound,’ which serves as a starting point for a person of ordinary skill developing the claimed invention.” (emphasis added)). 13 Appeal 2017-006257 Application 11/347,251 are not persuaded that the Examiner made a reversible error in rejecting claim 21. SUMMARY We affirm the rejections of claims 1-10, 20-23, 26^43, 45, and 46 under 35 U.S.C. § 103. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a)(l)(iv). See 37 C.F.R. § 41.50(f).
