              Appeal No. 2003-0265                                                                Page 3                
              Application No. 09/105,150                                                                                


                                                       OPINION                                                          
                     In reaching our decision in this appeal, we have given careful consideration to                    
              the appellants' specification and claims, to the Crowther patent, and to the respective                   
              positions articulated by the appellants and the examiner.  Upon evaluation of all the                     
              evidence before us, it is our conclusion that the evidence adduced by the examiner is                     
              insufficient to establish a prima facie case of obviousness with respect to the claims                    
              under appeal.  Accordingly, we will not sustain the examiner's rejection of claims 1, 4 to                
              16 and 18 under 35 U.S.C. § 103.  Our reasoning for this determination follows.                           


                     In rejecting claims under 35 U.S.C. § 103, the examiner bears the initial burden                   
              of presenting a prima facie case of obviousness.  See In re Rijckaert, 9 F.3d 1531,                       
              1532, 28 USPQ2d 1955, 1956 (Fed. Cir. 1993).  A prima facie case of obviousness is                        
              established by presenting evidence that would have led one of ordinary skill in the art to                
              combine the relevant teachings of the references to arrive at the claimed invention.                      
              See In re Fine, 837 F.2d 1071, 1074, 5 USPQ2d 1596, 1598 (Fed. Cir. 1988) and In re                       
              Lintner, 458 F.2d 1013, 1016, 173 USPQ 560, 562 (CCPA 1972).                                              


              The claimed subject matter                                                                                
                     Claims 1, 11 and 16, the independent claims on appeal, read as follows:                            
                     1.     A terminal assembly, comprising:                                                            
                            a terminal base having a bore with a internal thread;
