          Appeal No. 98-2888                                                          
          Application No. 29/044,927                                                  


               The viewpoints of the appellants are set forth in the                  
          Brief (Paper No. 11).                                                       
                                       OPINION                                        
               The appellants’ design is for combined abrasive disk and               
          spindle for dental use.  As best seen in Figures 5-7, the                   
          design has a handle having portions of two different diameters              
          and ending in an angled disk holding portion that holds an                  
          enlarged disk.  As can be seen in Figures 2 and 3, the                      
          abrasive disk has a square aperture with a single rectangular               
          slit extending across its width.                                            
               We begin our analysis by pointing out that the standard                
          for evaluating the patentability of a design is whether it                  
          would have been obvious to a designer of ordinary skill in the              
          articles involved.  See In re Nalbandian, 661 F.2d 1214, 1216,              
          211 USPQ 782, 784 (CCPA 1981).  In rejecting a claim to an                  
          ornamental design under 35 35 U.S.C. § 103, the examiner must               
          supply a basic design reference that bears a substantially                  
          identical visual appearance to the claimed design.  In re                   
          Harvey, 12 F.3d 1061, 1063, 29 USPQ2d 347, 349 (Fed Cir.                    
          1993).  That is, there must be a reference, a something in
