                     The prior art reference Masayuki does not provide the motivation to arrive at the claimed          
              subject matter.  According to the rejection, Masayuki teaches using an ethoxylated acrylate               
              monomer that is poorly miscible with a chosen liquid crystalline material and because of this has         
              a phase separation problem that is controlled by the addition of a miscible oligomer mixture.             
              However, we observe that Masayuki does not mention, let alone suggest, selecting a liquid                 
              crystalline material and an ethoxylated acrylate monomer that is miscible with the selected liquid        
              crystalline material.                                                                                     
                     We are not persuaded that a potential phase separation problem between a monomer and               
              a liquid crystalline material leads one of ordinary skill in the art to select a liquid crystalline       
              material and an ethoxylated acrylate monomer that is miscible with the selected crystalline               
              material.  Even if we accept the fact that routine experimentation would allow a person of                
              ordinary skill in the art to obtain such a mixture, this does not explain why one of ordinary skill       
              in the art would desire such a mixture or be guided toward such a mixture.  Specifically, while           
              routine experimentation on a known set of components may be obvious, we do not see where                  
              Masayuki or the prior art in general directs one of ordinary skill in the art to select appellants’       
              particular materials, i.e., a liquid crystalline material and an ethoxylated acrylate monomer that        
              are miscible with each other.                                                                             
                     The Office has the burden of establishing a prima facie case of obviousness.  Based upon           
              the record presented, we are unable to conclude that one of ordinary skill in the art would have          
              been motivated to select the appropriate liquid crystalline material and (1a) an ethoxylated
