          Appeal No. 96-2142                                                          
          Application 08/284,388                                                      


               Unpublished (or non-precedential) opinions of the                      
               Federal Circuit are not precedent in the Federal                       
               Circuit and will not be cited, considered, or regarded                 
               as precedent by the EIC, the Board, or any other                       
               tribunal within the Patent and Trademark Office.                       

               In any event, we do not consider appellants' argument                  
          concerning nonanalogous art to be well taken.  The test for                 
          determining whether prior art is analogous is well established;             
          as set forth in In re Clay, 966 F.2d 656, 658, 23 USPQ2d 1058,              
          1060 (Fed. Cir. 1992) (referred to in Oscar Mayer):                         
               Two criteria have evolved for determining whether prior                
               art is analogous: (1) whether the art is from the same                 
               field of endeavor, regardless of the problem addressed,                
               and (2) if the reference is not within the field of the                
               inventor's endeavor, whether the reference still is                    
               reasonably pertinent to the particular problem with                    
               which the inventor is involved.  In re Deminski, 796                   
               F.2d 436, 442, 230 USPQ 313 (Fed. Cir. 1986); In re                    
               Wood, 599 F.2d 1032, 1036, 202 USPQ 171, 174 (CCPA                     
               1979).                                                                 
          In the present case, Theurer '753 meets the first of these                  
          criteria since, being directed to a mobile track correction                 
          machine, it is clearly from the same field of endeavor as                   
          appellants' invention.  The argument in the reply brief that                
          appellants' "field of endeavor" is the same as the particular               






                                          3
