              Appeal No. 2000-0453                                                                                        
              Application No. 09/083,901                                                                                  


                     With respect to independent claim 10, the examiner has not shown that                                
              individual references or the combination of references teaches or fairly suggests the                       
              claimed invention.  The examiner relies on routine level of skill in the art to determine                   
              the optimum values for operation.  We disagree with the examiner characterization of                        
              the invention and lack of any evidence or convincing line of reasoning to support the                       
              examiner’s position.  Therefore, we agree with appellant that the examiner has not                          
              established a prima facie case of obviousness of the claimed invention, and we will not                     
              sustain the rejection of independent claim 10 and its dependent claims 11-14.                               
                     With respect to independent claim 15, as discussed above the examiner has not                        
              shown that the prior art to Gegner and Butcher teach or suggest the use of less than                        
              five windings on the secondary and similarly, the examiner has not shown that they                          
              teach or suggest the use of a single winding on the secondary.  Therefore, we will not                      
              sustain the rejection of independent claim 15 and its dependent claims 16-18.                               













                                                           5
