                Appeal No.  2007-1111                                                  Page 7                
                Application No.  10/126,804                                                                  
                protection .   . . .”  Id.  We note, however, that claim 1 does not require the              
                container to exhibit any particular amount of color protection.  To the contrary,            
                claim 1 simply requires that the container be substantially opaque.  In our                  
                opinion, the combination of references relied upon by the examiner teaches a                 
                container within the scope of appellants’ claimed invention.  Accordingly we are             
                not persuaded by appellants’ assertion and evidence which is not commensurate                
                in scope with claim 1.                                                                       
                      On reflection we find no error in the examiner’s prima facie case of                   
                obviousness.  Accordingly, the burden of coming forward with evidence or                     
                argument was properly shifted to appellant.  In re Rijckaert, 9 F.3d 1531, 1532,             
                28 USPQ2d 1955, 1956 (Fed. Cir. 1993).  For the reasons set forth above,                     
                appellants failed to carry their burden.  Therefore, we affirm the rejection of claim        
                1 under 35 U.S.C. § 103 as being unpatentable over the combination of ‘653,                  
                Wilcox, Akao and Keller.  Claims 2-9, 15-17, 19-23, 29 and 30 fall together with             
                claim 1.                                                                                     

                The combination of ‘653, Wilcox, Akao, Keller and appellants’ admitted prior art:            
                      Claims 13, 14, 27 and 28 stand rejected under 35 U.S.C. § 103 as being                 
                unpatentable over the combination of ‘653, Wilcox, Akao, Keller and appellants’              
                admitted prior art.  As set forth above, we limit our discussion to claim 13.  The           
                examiner relies on the combination of ‘653, Wilcox, Akao, and Keller as set forth            
                above.  Answer, page 7.  The examiner relies on appellants’ admitted prior art to            
                teach “that it was known to make dental adhesives with a color changeable dye                
                for changing from a distinctive color upon curing to one essentially ‘colorless’ for
