Appeal No. 2001-0214 Application No. 08/826,283 metal elements for use in Chagnon[‘s] lubricant composition and colloidal with the same attendant functional use. Moskowitz provides the motivation to use Chagnon[‘s] modified lubricant composition and colloidal suspension in rolling elements to fill the surface asperities and extend the life of the bearings. This position, however, is flawed as it does not provide sufficient factual bases for combining the teachings of the applied prior art references to arrive at the claimed composition. In re Warner, 379 F.2d 1011, 1017, 154 USPQ 173, 177-78 (CCPA 1967), cert. denied, 389 U.S. 1057 (1968), reh’g denied, 390 U.S. 1000 (1968)(the examiner has the initial burden of presenting a sufficient factual basis to support the obviousness of making the claimed combination). Specifically, the examiner has not demonstrated that Verdone teaches that its process for producing a silver colloidal suspension is useful for forming the ferrofluid of the type described in Chagnon. Nor has the examiner demonstrated that the silver colloidal suspension taught in Verdone is useful for the purpose or utility described in Chagnon. Even if the remaining prior art references teach that “metals are functional[ly] equivalent in a colloidal suspension” as alleged by the examiner, that fact alone does not indicate that there is requisite suggestion or motivation to select the claimed metals and attach 5Page: Previous 1 2 3 4 5 6 7 8 9 NextLast modified: November 3, 2007
