                 Application No. 08/155,987                                                                                                             


                 prior art.  In re Warner, 379 F.2d 1011, 1017, 154 USPQ 173,                                                                           
                 178 (CCPA 1967), quoted in In re                                                                                                       
                 GPAC, Inc., 57 F.3d 1573, 1582, 35 USPQ2d 1116, 1123 (Fed.                                                                             
                 Cir. 1995).  Here, the reasons given by the examiner as the                                                                            
                 basis of his finding of obviousness are unsupported by any                                                                             
                 evidence, and                                                                                                                          
                 appear to be based on improper hindsight gleaned from                                                                                  
                 appellant's own disclosure.                                                                                                            


                          Secondly, even if we were to agree with the examiner that                                                                     
                 it would have been obvious to modify Brezosky by using a                                                                               
                 compressible and/or flexible member as the element 82 of                                                                               
                 Brezosky, claim 41's requirement of a spring would still not                                                                           
                 be met.  On page 6 of the brief, appellant cites a dictionary                                                                          
                 definition of the term "spring" as "An elastic, stressed,                                                                              
                 stored-energy machine element that, when released, will                                                                                
                 recover its basic form or position . . . ."  If Brezosky's                                                                             
                 member 82 were made of a compressible or flexible material it                                                                          
                 would not meet this definition of a spring,  nor would the use               2                                                         

                          2Although a spring would normally be compressible and                                                                         
                 flexible, not every compressible and/or flexible element is a                                                                          
                                                                           4
