               Appeal No. 1999-0426                                                                                                
               Application No. 08/247,894                                                                                          


               sealant of Jervis in the case of Koblitz and that the examiner has offered no motivation                            
               “other than his unsupported conclusion that it would be obvious to do so.”  (See brief at                           
               page 8.)  We agree with appellants that the examiner has not supported his conclusion that                          
               it would have been obvious to one of ordinary skill in the art at the time of the invention to                      
               select sealants with the claimed properties.  Therefore, we cannot sustain the examiner’s                           
               rejection of claims 1-4, 6, 8-10, and 16.                                                                           




























                                                                6
