Appeal No. 97-1037 Application 08/467,869 skill in the art, from a combined assessment of the applied prior art, to vulcanize a rubber layer between the metal plates of a constraint type of vibration damper such as that taught by Niwa (Figure 2). From our perspective, the incentive on the part of one having ordinary skill in the art for making this modification would have simply been to obtain the expected benefit of this alternative practice of rubber vulcanization, a practice well known in the vibration damping device art, as revealed by the British document. As explained above, Niwa would have been suggestive of a thinner damping layer, as claimed. As to the recitation in claim 1 of the rubber layer being a “sheet that is formed and subsequently” vulcanized, we note that the patent- ability of an article does not depend on its method of produc- tion. See In re Thorpe, 777 F.2d 695, 697, 227 USPQ 964, 966 (Fed. Cir. 1985). While in the final article (insert), as claimed, it does not appear that the initial sheet form of the rubber layer would be discernible, we do recognize that the Niwa disclosure is nevertheless suggestive of applying rubber in sheet form, as pointed out, supra. For these reasons, we affirm the 9Page: Previous 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 NextLast modified: November 3, 2007
