GRIMES, TA WEN CHANG, and DAVID COTTA, Administrative Patent Judges. COTTA, Administrative Patent Judge. DECISION ON APPEAL This is an appeal under 35 U.S.C. § 134 involving claims to a photoprotective composition. The Examiner rejected the claims on appeal under 35 U.S.C. § l 12(b) as indefinite, under 35 U.S.C. § 103(a) as obvious, and on the ground non-statutory obviousness-type double patenting. We affirm. 1 According to Appellants, the real party in interest is L'Oreal. App. Br. 2. Appeal2017-006451 Application 12/808,839 STATEMENT OF THE CASE Claims 1-7 and 9-24 are on appeal. Claim 1, the only independent claim on appeal, is illustrative and reads as follows: 1. A photoprotective compos1t10n containing, m a cosmetically acceptable medium, a) as liquid phase, an oil-in-water emulsion, emulsified with at least one dimeric surfactant comprising two surfactant units, which may be identical or different, each being constituted of a hydrophilic head and a hydrophobic tail and connected to one another, via the hydrophilic heads, by means of a spacer group, b) at least one organic UV screen and/ or at least one mineral UV screen, and c) at least one crosslinked copolymer of methacrylic acid and of C1-C4 alkyl acrylate, wherein the methacrylic acid is present in amounts ranging from 20% to 80% by weight relative to the total weight of the copolymer, and the alkyl acrylate is present in amounts ranging from 15% to 80% by weight, relative to the total weight of the copolymer; the at least one copolymer of methacrylic acid and of C1-C4 alkyl acrylate is crosslinked with at least one ethylenically polyunsaturated crosslinking agent, and wherein particles of the copolymer in a dispersion have an average size between 10 and 500 nm; and wherein the composition has a viscosity of less than or equal to 200mPa·s, measured at 25 QC using a Rheomat RM 180 with a rotor 2 at a shear rate gradient of 200 s-1. App. Br. 16. During prosecution, in response to requirement for an election of species, Appellants elected sodium dicocoylethylenediamine PEG-15 sulfate as the claimed dimeric surfactant and a copolymer of methacrylic acid and ethyl acrylate as the claimed cross-linked copolymer. Ans. 5. The claims stand rejected as follows. 2 Appeal2017-006451 Application 12/808,839 Claims 1-7 and 9-24 were rejected under 35 U.S.C. § 112(b) as indefinite for failing to particularly point out and distinctly claim the subject matter which the inventor regards as the invention. Claims 1-7 and 9-24 were rejected under 35 U.S.C. § I03(a) as obvious over the combination of Sanogueira, 2 Carbopol®, 3 Candau, 4 and Maubru. 5 Claims 1-7 and 9-24 were rejected under 35 U.S.C. § I03(a) as obvious over the combination of Candau, Librizzi, 6 and McNamara. 7 Claims 1-7 and 9-24 were rejected on the ground of non-statutory obviousness-type double patenting over claims 1-21 of US Patent No. 7,959,903 in view of Librizzi. Claims 1-7 and 9-24 were provisionally rejected on the ground of non-statutory obviousness-type double patenting over claims 1-20 of US Patent Application No. 13/882,908 (now US Patent No. 9,925,132) in view of Sanogueira. Claims 1-7 and 9-24 were provisionally rejected on the ground of non-statutory obviousness-type double patenting over claims 1-17 of US Patent Application No. 13/099,225 ("the '225 application") in view of 2 Sanogueira et al., WO 2004/105704 A2, published Dec. 9, 2004 ("Sanogueira"). 3 Lubrizol Product Specification sheet for Carbopol® Aqua SF-I Polymer, effective August 1, 2002 ("Carbopol®"). 4 Candau et al., US Patent Publication No. 2005/0063925 Al, published Mar. 24, 2005 ("Candau"). 5 Maubru, US Patent No. 7,258,852 B2, issued Aug. 21, 2007 ("Maubru"). 6 Librizzi et al., US Patent Publication No. 2005/0070452 Al, published Mar. 31, 2005 ("Librizzi"). 7 McNamara, US Patent Publication No. 2005/0136013 Al, published June 23, 2005 ("McNamara"). 3 Appeal2017-006451 Application 12/808,839 Librizzi. In the Examiner's Answer, the Examiner withdrew this rejection because the '225 application had been abandoned. Ans. 2. Accordingly, this rejection is no longer part of this appeal. INDEFINITENESS In the Final Office Action, 8 the Examiner rejected claim 1 as indefinite on the basis that the claim requirement for determining viscosity "using a Rheomat RM 180 ... " was unclear. Final Act. 3. After considering Appellants' Appeal Brief, the Examiner withdrew this rationale for finding claim 1 indefinite. Ans. 2. The Examiner also rejected claim 1 as indefinite because the claim term "a dispersion" was unclear. Id. at 4. Appellants did not address this rationale in their Appeal Brief, raising it only in their Reply Brief. App. Br. 5---6; Reply Br. 1-2. We find that Appellants waived this argument because it was not included in the principal brief, depriving us of the Examiner's response. 37 C.F.R. § 41.4l(b)(2); see also, Exparte Borden, 93 USPQ2d 14 73, 14 7 4 (BP AI 2010) (informative) (" [T]he reply brief [is not] an opportunity to make arguments that could have been made in the principal brief on appeal to rebut the Examiner's rejections, but were not"). Accordingly, we summarily affirm the Examiner's indefiniteness rejection. See Manual of Patent Examining Procedure§ 1205.02 ("If a ground of rejection stated by the examiner is not addressed in the appellant's brief, that ground of rejection will be summarily sustained by the Board."). 9 8 Office Action mailed February 10, 2016 ("Final Act."). 9 In their Reply Brief Appellants represent that they will amend claim 12 to address the Examiner's rejection of that claim as indefinite because the claim terms "cinnamic" and "salicylic" were unclear. Reply Br. 2. We do not address whether such an amendment would obviate the Examiner's rejection because the issue is not properly before us. 4 Appeal2017-006451 Application 12/808,839 OBVIOUSNESS OVER SANOGUEIRA, CARBO POL®, CANDAU, ANDMAUBRU Appellants argue claims 1-7 and 9-24 together. We designate claim 1 as representative. Sanogueira discloses a stable and flexible emulsion base for use in formulating cosmetic and dermatological compositions. Sanogueira, 4. The Examiner found that Sanogueira discloses most of the elements recited in claim 1. Final Act. 9-10. The Examiner acknowledged that Sanogueira did not expressly disclose a composition comprising the elected cross-linked copolymer, but found that Sanogueira taught that its compositions include "one or more thickeners such as 'acrylates copolymer."' Id. at 11; Ans. 5. Based on the product specification sheet for Carbopol® Aqua SF-I Polymer, the Examiner concluded that the "acrylates copolymer" disclosed in Sanogueira was, in fact, Carbopol® Aqua SF-I Polymer. Id. The Examiner then relied upon the Specification as evidence that Carbopol® Aqua SF-I Polymer was the elected cross-linked copolymer. Ans. 5. (citing Spec. 15- 16). The Examiner concluded that it would have been obvious to include Carbopol® Aqua SF-I, as suggested by Sanogueira, because Sanogueira taught that it was a suitable thickener. Final Act. 12. With respect to the requirement of claim 1 that the particles of the copolymer "have an average size between 10 and 500 nm," the Examiner found that particles of Carbopol® Aqua SF-I were the same as the claimed particles and would thus inherently have an average size between 10 and 500 nm. Id. at 11. The Examiner also cited Maubru as evidence that the claimed particles would inherently meet the claimed particle size limitation. Id. Maubru discloses a composition comprising a "crosslinked copolymer of methacrylic acid and of a C1-C4 alkyl acrylate," including, more specifically, 5 Appeal2017-006451 Application 12/808,839 the elected copolymer of methacrylic acid and ethyl acrylate. Maubru, 2:34-- 47. Maubru further discloses that the "number-average size of the copolymer particles" is "generally, for example, from 10 to 500 nm." Id. at 3:1-8. With respect to the requirement of claim 1 that the composition "has a viscosity of less than or equal to 200 mPa·s," the Examiner found that Candau disclosed "oil-in-water emulsion compositions similar to those of SANOGUEIRA, and suggest[ s] the viscosity is suitably in the range of less than 200 mPa*s and preferably between 10 and 180 mPa*s." Final Act. 12. The Examiner concluded that it would have been obvious to "adjust the composition to a consumer-acceptable viscosity as suggested by CANDAU." Id. We agree with the Examiner that the composition of claim 1 would have been obvious over the cited references. We address Appellants' arguments below. Appellants argue that Sanogueira makes only a "very generic mention of 'acrylates copolymers' ... along with numerous other different and diverse possible thickeners." App. Br. 7. Similarly, Appellants argue that "nothing in Sanogueira suggests selecting the 'acrylates copolymers' out of the various possibilities and then to further select a copolymer of the type claimed." Id. at 9. We are not persuaded because the Examiner provided persuasive evidence that Sanogueira's reference to "acrylates copolymer" was, in fact, a reference to the elected cross-linked copolymer of methacrylic acid and ethyl acrylate. Ans. 5. Moreover, the fact that Sanogueira discloses "acrylates copolymer" as one among numerous thickeners that can be used does not make its use nonobvious. Sinclair & Carroll Co. v. 6 Appeal2017-006451 Application 12/808,839 Interchemical Corp., 325 U.S. 327, 335 (1945) ("Reading a list and selecting a known compound to meet known requirements is no more ingenious than selecting the last piece to put into the last opening in a jig-saw puzzle."); see also Merck & Co. v. Biocraft Laboratories, Inc., 874 F.2d 804, 807 (Fed. Cir. 1989) ("That the '813 patent discloses a multitude of effective combinations does not render any particular formulation less obvious."). Appellants argue that there is nothing in the product specification for Carbopol® Aqua SF-I that "suggests using the polymer therein in a photoprotective composition" as claimed. App. Br. 8. We are not persuaded because the Examiner does not rely on the product specification for Carbopol® Aqua SF-I for the suggestion to use Carbopol® Aqua SF-I. Rather, the Examiner relies on Sanogueira for this suggestion. See Final Act. 12 ("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 product Carbopol® Aqua SF-I (i.e. acrylates copolymer), as suggested by SANOGUEIRA, and produce the instantly claimed invention") ( emphasis added). Appellants argue that Sanogueira's preference for a thickener other than acrylates copolymer weighs against a determination of obviousness. App. Br. 9. We are not persuaded because, as the Federal Circuit has explained, "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, 87 4 F .2d at 807 (quoting In re Lamberti, 545 F.2d 747, 750 (CCPA 1976)) (alteration in original). 7 Appeal2017-006451 Application 12/808,839 Appellants argue that Maubru teaches away from the claimed composition by teaching that acrylic polymers of the Carbopol® type "can have the drawback of reducing the cosmetic performance of shampoos, for example, by making the hair more laden and coarser." App. Br. 10. We are not persuaded because Appellants do not explain how drawbacks associated with a shampoo apply to a photoprotective composition like that claimed. Even assuming the drawbacks of "making the hair more laden and coarser" apply to photoprotective composition, Appellants' argument would not be persuasive because the Examiner relied upon Maubru only to show the size of the prior art cross-linked copolymer particles (Final Act. 11 ). Moreover, Maubru expressly teaches that "[u]se can ... be made of the crosslinked methacrylic acid/ethyl acrylate copolymer ... manufactured and sold under the name Carbopol Aqua SF-I by the company Noveon" (Maubru 3: 11-14) and Sanogueira teaches that "acrylates copolymer" can be used as a thickener. Sanogueira 7. The drawbacks of using a copolymer of methacrylic acid and ethyl acrylate in shampoo compositions must be balanced against these teachings suggesting their beneficial use. See Medichem, S.A. v. Rolabo S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006) ("[A] given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine."). Finally, Appellants argue that Candau - which the Examiner relies upon as teaching compositions having a viscosity of less than or equal to 200 mPa·s - uses associative polymers and that "the copolymers employed according to the present invention differ from associative polymers and provide significantly different results when used in the types of compositions required by the present invention." App. Br. 9. We are not 8 Appeal2017-006451 Application 12/808,839 persuaded. As the Examiner points out, the claims do not require stability and the reference, Candau "teaches a viscosity that is coextensive with that now claimed, that is, the viscosity is suitably in the range of less than 200 mPa*s and preferably between 10 and 180 mPa*s, as measured at 25°C." Ans. 9. Accordingly, we affirm the Examiner's rejection of claim 1. Because they were not argued separately, claims 2-7 and 9-24 fall with claim 1. OBVIOUSNESS OVER CANDAU, LIBRIZZI, AND MCNAMARA Appellants argue claims 1-7 and 9-24 together. We designate claim 1 as representative. Candau discloses "[ o ]il-in-water photoprotective emulsions containing gemini surfactants and associative polymers." Candau Abstract. The Examiner found that Candau discloses most of the elements recited in claim 1. Final Act. 16-17. The Examiner acknowledged that Candau did not expressly disclose a composition comprising the elected cross-linked copolymer, but found that Candau taught that the associative polymer in its composition "is, for example, a copolymer formed from methacrylic acid and lower acrylates such as cross-linked terpolymers of methacrylic acid, ethyl acrylate and polyethylene glycol (10 EO) stearyl alcohol ether." Id. at 17. The Examiner found that Librizzi disclosed "methods for reducing irritation in personal care compositions comprising anionic surfactants" by including "hydrophobically-modified acrylic polymers," including, specifically, Carbopol® Aqua SF-I. Id. at 18. The Examiner further found 9 Appeal2017-006451 Application 12/808,839 that McNamara disclosed "stabilized sunscreen compositions including an acrylate polymer such as Carbopol Aqua SFI ." Id. Based on the disclosures of Candau and Librizzi, the Examiner concluded that it would have been obvious to combine "the anionic associative copolymer product Carbopol Aqua SF- I with a[] skin treating composition such as the oil-in-water photoprotective emulsions of CANDAU because the skin irritation of the resulting sunscreen product would have been decreased, as suggested by LIBRIZZI." Id. In addition, the Examiner concluded that it would have been obvious to "combine the acrylate copolymer product Carbopol Aqua SF-I with an oil-in-water photoprotective emulsions of CANDAU because MCNAMARA teaches this polymer as suitable [for use in] sunscreen compositions." Id. at 18-19. We agree with the Examiner that the composition of claim 1 would have been obvious over the cited references. We address Appellants' arguments below. Appellants argue that "nothing in Librizzi suggests using the polymer therein in a photoprotective composition." App. Br. 10. Appellants concede that Librizzi "mentions the use of Carbopol® Aqua SF-I Polymer to bind surfactants in the compositions therein to form reduced irritation compositions," but contend that "[i]t is not apparent that the compositions of Candau with the Gemini surfactants are even irritating compositions." Id. at 10-11. We are not persuaded. As the Examiner explains: LIBRIZZI teaches that the property of irritation is associated with personal care products that include anionic surfactants (abstract, [0004]). CANDAU teaches the Gemini surfactant species sodium dicocoylethylenediamine PEG-15 sulfate ([0094 ]), and as noted in paragraphs [0092] to [0094] this 10 Appeal2017-006451 Application 12/808,839 species is an anionic surfactant. Accordingly, the motivation to use the product Carbopol® Aqua SF-I taught by LIBRIZZI to reduce the irritation associated with personal care products that include anionic surfactants flows clearly from the combination of cited references. Ans. 11. Appellants argue that McNamara describes Carbopol® Aqua SF-I "as a homopolymer instead of copolymer" and that the skilled artisan "would [ not have] chosen this polymer to solve the problem addressed by the present invention, since such is described as a homopolymer and is not used in the examples." App. Br. 11. We are not persuaded. As an initial matter, we agree with the Examiner that "one of ordinary skill in the art would have been able to recognize Carbopol® Aqua SF- I as a copolymer suggested by McNamara with little effort, for example, simply looking up a product catalogue ofNoveon products." Ans. 12. Moreover, Appellants have not provided persuasive evidence that the skilled artisan would have been discouraged from using a homopolymer. See Johnston v. IVAC Corp., 885 F.2d 1574, 1581 (Fed. Cir. 1989) ("Attorneys' argument is no substitute for evidence."); In re Pearson, 494 F.2d 1399, 1405 (CCPA 1974). Finally, that the motivation to combine the references proffered by the Examiner - to minimize irritation - may not mirror the motivation of the inventors does not preclude a finding of obviousness. See KSR Int 'l Co. v. Teleflex Inc., 550 U.S. 398, 419 (2007) ("In determining whether the subject matter of a patent claim is obvious, neither the particular motivation nor the avowed purpose of the patentee controls. What matters is the objective reach of the claim. If the claim extends to what is obvious, it is invalid under § 103."); see also In re Beattie, 974 F.2d 1309, 1312 (Fed. Cir. 1992) 11 Appeal2017-006451 Application 12/808,839 ("[T]he law does not require that the references be combined for the reasons contemplated by the inventor"). Appellants argue that "[p ]ersons skilled in the art ... would not be led by Librizzi or McNamara to substitute the polymer therein for the associative polymers in Candau and expect to obtain the improved results according to the present invention" and that "replacing the associative polymers from Candau would be contrary to the objectives therein since the associative polymers are considered an important aspect of the invention [ of] Candau." App. Br. 11-12. We are not persuaded. We agree with the Examiner that Librizzi provides "motivation to use the product Carbopol® Aqua SF- I to reduce the irritation associated with personal care products that include anionic surfactants" and McNamara teaches that Carbopol® Aqua SF- I is "suitable [ for use in] sunscreen compositions." Ans. 12. Moreover, as the Examiner explains, the claims are open ended and do not preclude the presence of associative polymers. Accordingly, the skilled artisan could simply add Carbopol® Aqua SF-I to Candau's composition rather than substitute it for Candau's associative polymers. Id. Appellants argue that McNamara's teaching that "Carbopol 934, 940 and 941 are [the] most preferred carbomers" weighs against a determination of obviousness. App. Br. 11. We are not persuaded because, as discussed above, "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, 87 4 F .2d at 807. 12 Appeal2017-006451 Application 12/808,839 Finally, Appellants argue that it is "imperative that secondary considerations also be evaluated." App. Br. 14. We do not disagree. However, Appellants present only attorney argument with respect to secondary considerations, not persuasive evidence that secondary considerations demonstrate the non-obviousness of the claimed composition. See Johnston v. IVAC Corp., 885 F.2d at 1581 ("Attorneys' argument is no substitute for evidence."). Accordingly, we affirm the Examiner's rejection of claim 1. Because they were not argued separately, claims 2-7 and 9-24 fall with claim 1. DOUBLE PATENTING The Examiner rejected claims 1-7 and 9-24 on the ground of non- statutory obviousness type double patenting over claims 1-21 of US Patent No. 7,959,903 in view of Librizzi. Appellants do not present any new arguments with respect to this rejection, arguing only that this rejection should be reversed for the reasons discussed in connection with regard to the obviousness rejection over the combination of Candau, Librizzi, and McNamara. App. Br. 14. Accordingly, we affirm this rejection for the reasons discussed above. The Examiner also rejected claims 1-7 and 9-24 on the ground of non-statutory obviousness type double patenting over claims 1-20 of US Patent Application No. 13/882,908 (now US Patent No. 9,925,132) in view of Sanogueira. Appellants do not present any arguments with respect to this rejection. Accordingly, we summarily affirm this rejection. See Manual of Patent Examining Procedure§ 1205.02 ("If a ground of rejection stated by the examiner is not addressed in the appellant's brief, that ground of rejection will be summarily sustained by the Board."). 13 Appeal2017-006451 Application 12/808,839 SUMMARY For the set forth herein, and in the Examiner's Answer and Final Office Action we affirm: the Examiner's rejection of claims 1-7 and 9-24 under 35 U.S.C. § 112(b) as indefinite; the Examiner's rejection of claims 1-7 and 9-24 under 35 U.S.C. § 103(a) as obvious over the combination of Sanogueira, Carbopol®, Candau, and Maubru; the Examiner's rejection of claims 1-7 and 9-24 under 35 U.S.C. § 103(a) as obvious over the combination of Candau, Librizzi, and McNamara; the Examiner's rejection of claims 1-7 and 9-24 on the ground of non-statutory obviousness type double patenting over claims 1-21 of US Patent No. 7,959,903 in view of Librizzi; and the Examiner's rejection of claims 1-7 and 9-24 on the ground of non-statutory obviousness type double patenting over claims 1-20 of US Patent Application No. 13/882,908 (now US Patent No. 9,925,132) in view of Sanogueira. No time period for taking any subsequent action in connection with this appeal may be extended under 37 C.F.R. § 1.136(a). See 37 C.F.R. § 1.136(a).
