Appeal No. 95-2700 Application 07/956,018 obviousness. While a reaction process may be unpatentable even when both the starting material and the product are not disclosed in the prior art, it is well settled that each case must be decided on its own particular facts. In re Durden, Jr. 763 F.2d 1406, 1410, 226 USPQ 359, 361 (Fed. Cir 1985). Also, no per se rule exists that a claimed process is obvious if the examiner, as here, shows that the prior art discloses "the same general process using "similar" starting materials". In re Ochiai 71 F.3d 1565, 1570, 37 USPQ2d 1127, 1132 (Fed. Cir. 1995). In the present case, as in Ochiai, we find, for the reasons set forth above, that the examiner has not established the obviousness of the claimed process. In conclusion, based on the foregoing, we are constrained to reverse the examiner's rejection. REVERSED MARY F. DOWNEY ) 5Page: Previous 1 2 3 4 5 6 7 NextLast modified: November 3, 2007
