          Appeal No. 97-1931                                                          
          Application 08/364,826                                                      


          rationale in support of the rejection and arguments in rebuttal             
          set forth in the examiner's answers.                                        
          It is our view, after consideration of the record before                    
          us, that the collective evidence relied upon and the level of               
          skill in the particular art would have suggested to one of                  


          ordinary skill in the art the obviousness of the invention as set           
          forth in claims 1-16, 18 and 22-25.  We reach the opposite                  
          conclusion with respect to claims 17 and 19-21.  Accordingly, we            
          affirm-in-part.                                                             
          The examiner has rejected each of claims 1-25 as being                      
          unpatentable over the teachings of Dworkin when considered in               
          combination with the skill of the artisan.  Dworkin is directed             
          to a computer which can determine all the products which meet a             
          user’s requirements, and can indicate to the user the supplier              
          and cost information for each of the products.  The user can then           
          order the product from the individual supplier based upon the               
          user’s criteria such as lowest price.  Thus, Dworkin relates to a           
          device for indicating to a customer which supplier can supply               
          specific products and at what cost.                                         
          Before we consider the specific claims on appeal before                     
          us, some general observations are in order.  There are initially
