COLAIANNI, GEORGE C. BEST, and N. WHITNEY WILSON, Administrative Patent Judges. WILSON, Administrative Patent Judge. DECISION ON APPEAL Appellants 1 appeal under 35 U.S.C. § 134(a) from the Examiner's January 9, 2017 decision finally rejecting claims 1-10, 12, and 15, which constitute all the claims pending in this application. Claims 11, 13, 14, and 17 are withdrawn from consideration as being directed to a non-elected invention. 2 We have jurisdiction over the appeal under 35 U.S.C. § 6(b). 1 Appellants state that the real party in interest is BASF Construction Solutions GmbH (Appeal Br. 2). 2 Appellants request correction of the status of claim 17 (Appeal Br. 6). The withdrawal of a claim from consideration pursuant to a restriction or election requirement is a petitionable matter not subject to review by the Board. See Appeal2017-010345 Application 14/34 7, 118 We affirm-in-part. CLAIMED SUBJECT MATTER Appellants' invention is directed to cement powder compositions for rapid suspension and a process for producing a liquid component thereof (Spec. 1: 1; 1:6-7). Independent claims 1 and 15 are reproduced below from the Claims Appendix of the Appeal Brief (emphasis added): 1. A pulverulent composition produced by bringing a powder which comprises at least one inorganic binder into contact with from 0.01 to 10% by weight, based on the total mass of the composition, of a liquid component comprising at least one copolymer obtained by polymerization of a mixture of monomers compnsmg (I) at least one ethylenically unsaturated monomer which comprises at least one radical selected from the group consisting of carboxylic acid, carboxylic acid salt, carboxylic esters, carboxamide, carboxylic anhydride and carboximide and (II) at least one ethylenically unsaturated monomer having a polyalkylene oxide radical, where the liquid component contains at least 1 % by weight of the at least one copolymer and at least 30% by weight of an organic solvent; wherein said bringing into contact occurs prior to adding make-up water to the powder. 15. A process for producing a liquid component comprising utilizing at least 30% by weight of an organic solvent, not more In re Berger, 279 F.3d 975, 984--85 (Fed. Cir. 2002) (petitionable issues are not subject to review by the Board). Accordingly, we cannot act on this request. 2 Appeal2017-010345 Application 14/34 7, 118 than 30% by weight of water and a copolymer obtained by polymerization of a mixture of monomers comprising (I) at least one ethylenically unsaturated monomer which comprises at least one radical selected from the group consisting of carboxylic acid, carboxylic acid salt, carboxylic ester, carboxamide, carboxylic anhydride and carboximide and (II) at least one ethylenically unsaturated monomer having a polyalkylene ether radical, characterized in that the polymerization of the monomers is carried out in a water containing solvent, where the water content of the total reaction mixture is more than 10% by weight, the polymerization product is admixed with an organic solvent and water is removed. DISCUSSION The only rejection on appeal is the rejection to claims 1-10, 12, and 15 as obvious over Yamashita. 3 Dependent claims 2-10 and 12 will stand or fall with claim 1. 37 C.F.R. § 4I.37(c)(l)(iv). Claim 15 will be addressed separately. Claim 1 There is no dispute that claim 1 is a product-by-process claim (Ans. 5; Appeal Br. 9). In rejecting claim 1, the Examiner finds that Yamashita discloses or suggests each step of the claimed process for making the pulverulent composition (Ans. 2-3). The Examiner further finds that although Yamashita does not disclose that the "bringing [ a powder] into contact [ with a liquid component] occurs prior to adding make-up water to the powder," Yamashita discloses that the composition disclosed therein includes water. 3 Yamashita et al., EP 1 437 330 Al, published July 14, 2004. 3 Appeal2017-010345 Application 14/34 7, 118 Id. at 3. According to the Examiner's construction of the claim, "it is not clear whether the recited 'make-up water' is a component of the claimed pulverulent composition." Id. at 5. Thus, the Examiner determined that a prima facie case of obviousness exists "[g]iven that Yamashita discloses a cement dispersant containing copolymer with an organic solvent and combining the same with a cement." Id. at 3. According to the Examiner, "it would have been obvious to a person having ordinary skill in the art at the time of invention to provide a pulverulent composition as claimed in order to provide high dispersibility[,] even when added in a small amount to a cement composition." Id. Appellants argue that the rejection of claim 1 should be reversed because "Yamashita discloses adding its dispersant to the mixing water, and subsequently adding this aqueous mixture to the inorganic binder system" (Appeal Br. 8). Appellants further argue that claim 1 is distinguished from Yamashita' s product because the ordinary skilled artisan would understand that "the claimed pulverulent composition is a pulverulent raw material." Id. at 9. Appellants contend that "[b ]ased on the plain reading of the claim language, it is clear that 'make-up water' is not a component of the claimed pulverulent composition" (Reply Br. 3). We begin by interpreting the language of claim 1. In particular, we construe the phrase "[a] pulverulent composition produced by bringing a powder ... into contact with ... a liquid component ... wherein said bringing into contact occurs prior to adding make-up water to the powder" ( emphasis added). During prosecution, the PTO gives the language of the proposed claims "the broadest reasonable meaning of the words in their ordinary 4 Appeal2017-010345 Application 14/34 7, 118 usage as they would be understood by one of ordinary skill in the art, taking into account whatever enlightenment by way of definitions or otherwise that may be afforded by the written description contained in the applicant's specification." In re Morris, 127 F.3d 1048, 1054--55 (Fed. Cir. 1997). In support of Appellants' position, the Specification provides that "[t]he pulverulent composition should ... preferably be present in dry form, which means that it has a water content determined by the Karl-Fischer method of less than 5% by weight, preferably less than 1 % by 40 weight and particularly preferably less than 0.1 % by weight" (Spec. 8:37--40). Furthermore, Appellants' arguments are persuasive that the "term 'make-up water' is widely recognized and well-known to those of ordinary skill in the art as referring to the water that is added to a cement mix in order to form hydration reaction products (i.e., concrete)" (Reply Br. 4). 4 See K-2 Corp. v. Salomon S.A., 191 F.3d 1356, 1365 (Fed. Cir. 1999) ("claim construction is firmly anchored in reality by the understanding of those of ordinary skill in the art"). Therefore, we determine that claim 1 requires that the pulverulent composition subject matter encompasses only two components: (1) "a powder" and (2) "a liquid component." The broadest reasonable interpretation of the phrase "wherein ... bringing into contact [ the powder and the liquid component] occurs prior to adding make-up water to the powder" is that the claimed "make-up water" is not a component of the pulverulent composition of claim 1. 4 See, e.g., Macauley, Jr., US 3,997,434, issued Dec. 14, 1976 (Abstract disclosing a concrete reclamation system in which clarified wash water is provided as make-up water for mixing with cement). 5 Appeal2017-010345 Application 14/34 7, 118 The Examiner has the initial burden of establishing a prima facie case of obviousness based on an inherent or explicit disclosure of the claimed subject matter under 35 U.S.C. § 103. In re Oetiker, 977 F.2d 1443, 1445 (Fed. Cir. 1992) ("[T]he examiner bears the initial burden, on review of the prior art or on any other ground, of presenting a prima facie case of unpatentability."). To establish a prima facie case of obviousness, the Examiner must show that each and every limitation of the claim is described or suggested by the prior art or would have been obvious based on the knowledge of those of ordinary skill in the art. In re Fine, 837 F.2d 1071, 1074 (Fed. Cir. 1988). In this instance, the Examiner has not shown that the bringing of a powder in contact with a liquid component and subsequent make-up water addition was taught or suggested by the cited prior art, as Yamashita does not teach such a process. Therefore, Appellants have persuasively argued that the facts and reasons relied on by the Examiner are insufficient to establish a prima facie case of obviousness as to independent claim 1. The rejection of dependent claims 2-10 and 12 are reversed for the same reason as independent claim 1. Accordingly, we reverse the rejection of claims 1-10 and 12 for the reasons set forth above. Claim 15 We note that for claim 15 on appeal, Appellants' briefs do not include any particularized argument based on that claim's limitations. Rather, Appellants' arguments urging reversal of claim 15 include a bare assertion that "Yamashita fails to disclose or suggest" the limitations recited therein. Appeal Br. 12. Appellants then state that the rejection of the claim should be reversed. Id. However, Appellants fail to identify reversible error in the 6 Appeal2017-010345 Application 14/34 7, 118 Examiner's findings that Yamashita discloses or suggests the claimed process for producing a liquid component. Ans. 9. Claim 15 does not recite the phrase "[a] pulverulent composition produced by bringing a powder ... into contact with ... a liquid component ... wherein said bringing into contact occurs prior to adding make-up water to the powder." Thus, the arguments we found persuasive in showing reversible error in the rejection of claim 1 are not pertinent with respect to claim 15. Accordingly, we affirm the rejection of claim 15 for the reasons set forth and explained in the Examiner's Answer. CONCLUSION We REVERSE the rejection of claims 1-10 and 12 under 35 U.S.C. §103(a) as obvious over Yamashita. We AFFIRM the rejection of claim 15 under 35 U.S.C. § 103(a) as obvious over Yamashita. 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). AFFIRMED-IN-PART 7 Copy with citationCopy as parenthetical citation
