              Appeal No. 1998-1850                                                                                          
              Application No. 08/596,613                                                                                    

              “an aspect ratio greater than about 4 to 1,” when following the combined teachings of the                     
              references.                                                                                                   
                     In this regard, we note that appellants mention (Brief, page 8) claiming aspect ratios                 
              of 4:1 to 5:1.  Although appellants have ostensibly chosen to rely on the limitations of                      
              independent claim 1, we note that instant claim 8 recites that the aspect ratio is “in a range                
              of between about 4 to 1 and about 5 to 1.”  For substantially the same reasons for our                        
              conclusion that an aspect ratio of “about 4 to 1” does not distinguish over the prior art, we                 
              also conclude that an aspect ratio of 5 to 1, or “about” 5 to 1, also fails to distinguish.  That             
              is, the combined teachings of Havemann and Tsunohara, based on the evidence before                            
              us, would have led the artisan to aspect ratios of 5 to 1 or about 5 to 1.                                    
                     We have also considered appellants’ additional argument on page 6 of the Reply                         
              Brief, disagreeing with the examiner’s finding of what structures define the “aspect ratio” in                
              the Havemann device.  Even accepting appellants’ arguments as accurately reflecting the                       
              facts of Havemann, we do not see, and appellants have not persuasively explained, how                         
              claim 1 might set forth a distinction over the structures disclosed by Havemann, as                           
              improved by the teachings of Tsunohara.                                                                       
                     Appellants rely on the arguments in regard to the combination of Havemann and                          
              Tsunohara, as applied against claim 1, in answer to the section 103 rejection of claim 12                     
              over Havemann, Tsunohara, and Sheng, and in answer to the section 103 rejection of                            
              claims 3, 4, 9, 41, and 42 over Havemann, Tsunohara, and the APA.  (See Brief, pages 8-                       

                                                            -8-
