                   Application No.  08/294,819                                                                                       

                                                   GROUND OF REJECTION                                                               
                           Claims 1-3 and 44 stand rejected under 35 U.S.C. § 103 as being                                           
                   unpatentable over Maggio in view of Mantyh.                                                                       
                           We reverse.                                                                                               
                                                          DISCUSSION                                                                 
                           In reaching our decision in this appeal, we considered appellants’                                        
                   specification and claims, in addition to the respective positions articulated by the                              
                   appellants and the examiner.  We make reference to the examiner’s Answer1 for the                                 

                   examiner’s reasoning in support of the rejection.  We further reference appellants’                               
                   Brief2, and appellants’ Reply Brief3 for the appellants’ arguments in favor of                                    

                   patentability.  We note that the examiner entered and considered appellants’ Reply                                
                   Brief.4                                                                                                           

                   THE REJECTION UNDER 35 U.S.C. § 103:                                                                              

                           The initial burden of presenting a prima facie case of obviousness rests on                               
                   the examiner.  In re Oetiker, 977 F.2d 1443, 1445, 24 USPQ2d 1443, 1444 (Fed.                                     
                   Cir. 1992).  In meeting this burden, we remind the examiner that “[t]he Patent Office                             
                   has the initial duty of supplying the factual basis for its rejection.  It may not, because                       
                   it may doubt that the invention is patentable, resort to speculation, unfounded                                   
                   assumptions or hindsight reconstruction to supply deficiencies in its factual basis.”                             


                                                                                                                                     
                   1 Paper No. 30, mailed July 7, 1998.                                                                              
                   2 Paper No. 27, received March 27, 1998.                                                                          
                   3 Paper No. 31, received Septemer 8, 1998.                                                                        
                   4 Paper No. 33, mailed November 24, 1998.                                                                         

                                                                 3
