          Appeal No. 2002-0178                                                        
          Application 09/385,909                                                      

          for the same reason discussed above with respect to claim 8, and            
          hence, because anticipation is the epitome of obviousness, we               
          affirm this rejection with respect to claim 9.                              
               With respect to claim 16, claim 16 depends upon claim 1 and            
          recites “wherein said ionic sulfonate monomer is sodium vinyl               
          sulfonate, or potassium vinyl sulfonate.”  The examiner relies              
          upon the secondary references of Puschak or Villiger to meet this           
          aspect of claim 16.  However, the examiner has not explained the            
          motivation of why one of ordinary skill in the art would have               
          utilized the sodium vinyl sulfonate as set forth in Villiger                
          (which is used in Villiger as a anchoring agent in promoting the            
          anchoring of an encapsulating polymer to the surfaces of colorant           
          particles during polymerization for ensuring that all the                   
          colorant particles are uniformly coated by the polymer).  Nor has           
          the examiner explained why one of ordinary skill in the art would           
          have substituted the sodium vinyl sulfonate of Puschak (Puschak             
          utilizes the sodium vinyl sulfonate as an acid functional monomer           
          to obtain a desired range of acid number).  The examiner has not            
          explained why either of these utilities would be useful in the              
          process of Collins.  In this context, we therefore agree with               
          appellants’ comments made on pages 8-9 of the brief.  We                    
          therefore reverse the rejection of claim 16.                                
          III. The rejection of claims 10 and 11 under 35 U.S.C.                      
               § 103 over Collins in view of Lundberg                                 
               We note that the claims 10 and 11 do not require alkylene.             
          That is, both claims 10 and 11 depend upon claim 8 and in claim             
          8, R' can be alkylene or –CO-R2.  Hence, when R' is –CO-R2, which           

                                       6
