Appeal No. 96-1286 Application 08/259,360 claim elements, all of which must be accounted for in establishing a case of prima facie obviousness. Moreover, neither Nissen nor Fuss is directed to a look- up table implementing logical functions for multiple variables. The general idea of grouping identical data to reduce memory requirements would not have reasonably suggested the specific features of the appellants’ claims concerning logical functions, grouping of output states each representing an array of logical function responses, elimination of selected output states and assignment of a programmable architecture element to the remaining output states. The mere fact that the prior art may be modified in the manner suggested by the examiner does not make the modification obvious unless the prior art suggested the desirability of the modification.

Obviousness may not be established using hindsight or in view of the teachings or suggestions of the inventor. Para- Ordnance Mfg. Inc. v.
