Appeal No. 1996-3017 Application No. 08/851,810 steps in a sublimation sequence along with their attendant advantages. In re Thompson, 545 F.2d 1290, 1294, 192 USPQ 275, 277 (CCPA 1976); In re Marzocchi, 456 F.2d 790, 793, 173 USPQ 228, 229-30 (CCPA 1972). As a final point, we note that appellant bases no argument upon objective evidence of nonobviousness, such as unexpected results which attach to the use of the claimed crystallization and sublimation techniques for isolating alkyl-pyrazines viz-à-viz the distillation and extraction techniques disclosed by the primary references. In conclusion, based on the foregoing and the reasons well-stated by the examiner, the examiner's decision rejecting the appealed claims is affirmed. -10-Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
