                    Application No. 09/188,766                                                                                                                            


                    With regard to the rejection of claims 1 through 3 and 5                                                                                              
                    through 9 under 35 U.S.C. § 103(a) as being unpatentable over the                                                                                     
                    APA and Isaji (final rejection, pages 2-3), we agree with                                                                                             
                    appellants' arguments in their brief and reply brief that the                                                                                         
                    examiner has disregarded the teachings of the Isaji patent as a                                                                                       
                    whole and instead improperly attempted to extract a generalized                                                                                       
                    concept from Isaji and then apply that general concept to the                                                                                         
                    clearly different refrigeration system of the APA, without any                                                                                        
                    teaching, suggestion, or incentive in the prior art itself for                                                                                        
                    any such combination.  More particularly, we agree with                                                                                               
                    appellants' arguments, analysis of the applied prior art and                                                                                          
                    commentary on the examiner's attempted combination of the APA and                                                                                     
                    Isaji as set forth on pages 8-12 of the brief and pages 2-12 of                                                                                       
                    the reply brief, and we adopt those positions as our own.                                                                                             


                    Like appellants, it is our opinion that the examiner has                                                                                              
                    improperly used the hindsight benefit of appellants' own                                                                                              
                    disclosure to fabricate a broad concept from the applied Isaji                                                                                        
                    patent and then selectively combine that broad concept with the                                                                                       
                    distinctly different refrigeration system of the APA in an                                                                                            
                    attempt to reconstruct appellants' claimed subject matter.                                                                                            
                    However, as our court of review indicated in In re Fritch,                                                                                            

                                                                                    44
