Appeal No. 96-0987 Application No. 08/226,467 appellants' example on page 6 of the specification as originally filed of "PU-type elastomer resins" as well as with the disclosure in the patent to Molitor of the formation of golf club heads from "low density, high strength material such as reaction injection molded (RIM) polyurethane" (column 2, lines 29-30). Thus, since Fenton discloses the thin layer of viscoelastic resin 23 to be "comprised of silicone rubber or a PVC plastisol or any synthetic or natural rubber" (column 2, lines 33-34), we reach the conclusion that the viscoelastic material of Fenton is not one capable of being molded by the RIM process. We next turn to the disclosure of Molitor which the examiner has relied upon for the teaching of the use of materials suitable for use with the RIM process as being well known in the art of making golf clubs. However, it is clear from the disclosure of Molitor that the use of RIM polyurethane is in a second embodiment of the invention wherein the entire club head is formed of "low density, high strength material such as reaction injection molded (RIM) polyurethane" (column 2, lines 28-30) with "insert weights molded into and encapsulated by the polyurethane material" (column 2, lines 32-33). The first embodiment is directed to club heads fabricated "as a hollow metal shell" (column 2, line 23), and there is no disclosure in 7Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
