Appeal 2006-2308 Application 10/343,154 on Hammer for the basic process of producing an adhesive closing part with a laterally and rotationally symmetrical structure using a pressure tool and a molding tool, where the molding tool has cavities with walls extending along a convex path. The Examiner concedes that Hammer does not disclose cavities having “a curvature in a form of a hyperboloid with a more pronounced portion defined by decreased radii of curvature and by narrowing of spaces between the boundary walls, each more pronounced portion being closer to a head molding part of the cavity than to a base molding part of the cavity.” (Answer 4). Accordingly, the Examiner relies on Thomas for a teaching of the claimed hyperboloid shape. (Answer 5) (citing embodiments shown in Fig. 6A to Fig. 9B, particularly Fig. 7A).3 According to the Examiner, Thomas “teaches that the length of the prong may be varied according to the material the shank is designed to intercept (9:62-10:24). Thomas also teaches the decreased radii of curvature and narrowing of spaces between the boundary walls, each more pronounced 3 “Thomas' figures show curvatures that encompass hyperboloid shapes, and in the alternative, the drawings and text of the Thomas patent provide clear suggestion and teaching that the particular curvature be changed and optimized.” (Answer 12). 5Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
