Appeal No. 95-5126
Application No. 08/045,675
Given the above teachings, we agree with the examiner
that it would have been obvious to employ dimethyl octadecyl
phosphonate (DMOP) as the alkyl or alkenyl phosphonate of
Barber’s gear lubricant composition with the reasonable
expectation of imparting an additional friction reducing
means. See also Merck & Co. v. Biocraft Labs., 874 F.2d 804,
807,
10 USPQ2d 1843, 1846 (Fed. Cir.), cert. denied, 493 U.S. 975
(1989); In re Susi, 440 F.2d 442, 444, 169 USPQ 423, 425 (CCPA
1971); In re Petering, 301 F.2d 676, 681, 133 USPQ 275, 280
