Appeal No. 2005-0484 Application No. 09/888,696 indicate that each of components A, B, and D, as prepared, contain a significant proportion of solids: Component A-36% solids (preparation A-1 and A-2); Component B-40% solids (preparation B-1, B-2, B-3, and B-4); Component D-60% solids (preparation D-1). Further, components C and E appear to be added to the composition as solids. Component C may constitute as much as 25% of the formulation; whereas component E may constitute as much as 3% (col. 12, ll. 44-53). Additionally, the Yamaki composition may contain a solid pigment component in amounts as high as approximately 50% by weight of the composition (col. 13, ll. 3-21). With the foregoing in mind, it can be discerned that the Yamaki disclosure does implicitly encompass formulations having a solids content exceeding 70% by weight. As explained by the examiner, it would have been prima facie obvious, within the ambit of 35 U.S.C. § 103, to balance the amount of solvent and solids in the Yamaki composition to obtain an optimum formulation especially in view of the recognized need in the art, as conceded by appellant (specification: p. 1, ll. 12-15), to minimize the volatile organic solvent content of coating compositions. 5Page: Previous 1 2 3 4 5 6 7 8 NextLast modified: November 3, 2007
