          Appeal No. 1997-4442                                                         
          Application 08/353,040                                                       

                                  DECISION ON APPEAL                                   
               This is a decision on appeal under 35 U.S.C.  134 from                 
          the Examiner's refusal to allow claims 2-6.                                  
               We reverse.                                                             
                                      BACKGROUND                                       
               The disclosed invention relates to precision resistors                  
          having accurate and readily reproducible values of resistance                
          and temperature coefficient of resistance ("TCR").                           
               Claim 6 is reproduced below.2                                           
               6.  A resistor comprising an electrically insulating                    
               substrate having two connections which are electrically                 
               interconnected by means of a resistance path, said                      
               resistance path comprising a first resistance alloy                     
               portion with a positive TCR and a second resistance alloy               
               portion with a negative TCR, and wherein the difference                 
               in the resistance values between first and second alloy                 
               portions is maximally a factor of 10 and the difference                 
               in the absolute values of the TCR between first and                     
               second alloy portions is maximally a factor of 10, the                  
               first and second portions both being trimmed so that the                
               resistor has a desired resistance value and a desired                   
               TCR.                                                                    



            As noted by the Examiner, "TRC" in claim 6 (four2                                                                       
          places) in the amendment after final rejection (Paper No. 13)                
          filed October 29, 1996, and in the appendix to the brief,                    
          should be "TCR" to be consistent with claim 6 as originally                  
          presented in the amendment (Paper No. 10) filed                              
          February 26, 1996.  We reproduce the claim with the                          
          correction.                                                                  
                                        - 2 -
