          Appeal No. 96-0775                                                          
          Application 07/990,769                                                      

          inductive write head and a magnetoresistive read head which                 
          includes biasing means.  It is the examiner's position that the             
          magnetic heads of both Mowry and Tanabe "will inherently exhibit            
          the claimed read head magnetic center, read head physical center,           
          and write head physical center positional relationships" during             
          the operation of the magnetic heads.  It is appellants' belief              
          (Brief, page 15) that:                                                      
               [A]n accidental achievement of a product or process                    
               does not constitute proper anticipation.  A true                       
               accident is never fully understood and gives no                        
               assurance that the same result can be achieved by                      
               others at a later time (emphasis in original).                         
               The bias sources in Mowry and Tanabe will indeed move a read           
          head and a write head with respect to each other, but the                   
          specifically claimed offset amounts and positional relationships            
          certainly "cannot be said to be 'the natural result flowing from            
          the operation as taught'" in each of the references.  See In re             
          Oelrich, 666 F.2d 578, 581, 212 USPQ 323, 326 (CCPA 1981).                  
          Accordingly, we agree with appellants that inherency may not be             
          established by probabilities or possibilities.  The anticipation            
          rejections of claims 2, 3, 9 and 10 based upon Mowry and Tanabe             
          are reversed.
