         Appeal No. 2006-2029                                                       
         Application No. 10/351,104                                                 

         to the present specification, the claimed tooth brush maximizes            
         the amount of light transmitted towards the user and encourages            
         the user to brush their teeth (see page 1 of specification).               
              Appealed claims 21-23 stand rejected under 35 U.S.C.                  
         § 103(a) as being unpatentable over Salmon in view of Robinson             
         and Derose.1                                                               
              Appellant has not presented separate arguments for claims             
         22 and 23.  Accordingly, all the appealed claims stand or fall             
         together with claim 21.                                                    
              We have thoroughly reviewed each of appellant’s arguments             
         for patentability.  However, we are in complete agreement with             
         the examiner that the claimed subject matter would have been               
         obvious to one of ordinary skill in the art within the meaning of          
         Section 103 in view of the applied prior art.  Accordingly, we             
         will sustain the examiner’s rejection for essentially those                
         reasons expressed in the answer, and we add the following                  
         primarily for emphasis.                                                    
              There is no dispute that Salmon, like appellant, discloses a          
         toothbrush having a portion of its body made of a clear material           

              1The examiner states at page 2 of the answer that “the 103            
         rejection of Salmon in view of Robinson and further in view of             
         Ishiharada is being dropped.”                                              
                                         3
