                  Application No. 08/780,204                                                                                                              


                  derivative of this function, each of the independent claims requires the final step of                                                  
                  “investigating spikes in said second derivative plot.”  Clearly, there is no evidence of                                                
                  record in this case that any advantage is to be obtained by such an investigation of

                           Since we find that the examiner has failed to establish a prima facie case of                                                  
                  obviousness with regard to the instant claimed subject matter, we will not sustain the                                                  
                  rejection of claims 1-6 and 8 under 35 U.S.C. § 103.                                                                                    
                           The examiner’s decision is reversed.
