              Appeal No. 1996-1581                                                                                          
              Application No. 08/149,815                                                                                    


                     In the face of appellants' showing of unexpected results, the examiner responds                        
              "Appellant has not provided any unexpected results that occur due to the claimed                              
              thicknesses, but has only offered general allegations of reduced cell defects and noise                       
              reduction."  (page 9 of answer).  When appellants pointed out in their reply brief that their                 
              principal brief argued the significance and unexpected nature of the comparative                              
                                  1                                                                                         
              specification data,  the examiner merely responded that the reply brief "has been entered                     
              and considered but no further response by the Examiner is deemed necessary."  (paper                          
              no. 23).                                                                                                      
                     Manifestly, it is incumbent upon the examiner to offer a critical analysis of evidence                 
              of non-obviousness presented by appellants.  See In re Margolis 785 F2d 1029, 1031,                           
              228 USPQ 940,  942 (Fed. Cir. 1986) and Pines v. McAllister 188 F.2d 388, 390, 89                             
              USPQ 312, 314 (CCPA 1951).  In the present case, the examiner's failure to critically                         
              asses the probative value of appellants' specification data constitutes reversible error.

                                                             5
