Appeal No. 2007-0179 Page 6 Application No. 10/601,856 ordinary skill in the art to which said subject matter pertains.” 35 U.S.C. § 103(a). To establish a prima facie case of obviousness, there must be some suggestion or motivation, either in the references themselves or in the knowledge generally available to one of ordinary skill in the art, to modify the reference or to combine reference teachings. See In re Vaeck, 947 F.2d 488, 20 USPQ2d 1438 (Fed. Cir. 1991); In re Dembiczak, 175 F.3d 994, 999, 50 USPQ2d 1614, 1617 (Fed. Cir. 1999). “The prima facie case is a procedural tool of patent examination, allocating the burdens of going forward as between examiner and applicant. . . . If that burden is met, the burden of coming forward with evidence or argument shifts to the applicant.” In re Oetiker, 977 F2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed. Cir. 1992). Here, we find that the Examiner has presented sufficient evidence to establish a prima facie case of obviousness. First, the Examiner has identified where the components of the claimed composition can be found in the prior art. Answer 3-4. Secondly, having described the differences between the claimed composition and the prior art (Answer 4), the Examiner explains why the skilled worker would have been motivated to have modified Jakura to have arrived at the claimed subject matter. Answer 4-5. Before summarizing the Examiner’s position, for clarity, we designate the free dicarboxylic acid (i.e., malonic acid) as species [1]; the half- or partly- neutralized acid (i.e., malonic acid substituted with one “cationic counter ion”) as species [2]; and the fully-neutralized acid (i.e., malonic acid substituted with two “cationic counter ions”; the “di-salt”) as species [3]. Jokura describes a skin composition having a molar ratio between the free acid [1] and fully neutralized acid [3]. Col. 3, ll. 51-60. In contrast, the claimed composition is limited to a different molar ratio which is between the half-neutralized [2] and fully neutralizedPage: Previous 1 2 3 4 5 6 7 8 9 10 11 Next
