                Appeal 2006-2159                                                                                 
                Application 09/862,234                                                                           

                i.e., non-fluid at room temperature (Decl. 3: ¶ 10; Simpson, col. 13, ll. 28-                    
                45, and Examples 1-5).  We determine that Simpson teaches that the                               
                combination of the solid and liquid components must be mixed together at                         
                sufficient temperature and shear to achieve dispersive mixing, with the fluid                    
                system held at a temperature that retains the required fluidity for the                          
                fabrication of the final product, generally at 80 to 120șC (col. 13, ll. 35-45),                 
                in contrast to Appellants’ process where the 100% solids composition has                         
                the required viscosity at room temperature (Specification 10, 17 and 19).                        
                       We also determine that Sartor does not remedy the deficiency of                           
                Simpson.  Sartor merely reinforces the teachings of Simpson, namely that                         
                the viscosity is important in the coating process and this viscosity can be                      
                controlled by the addition of thinners (Sartor, col. 11, ll. 47-57; col. 12, ll. 9-              
                17; and Simpson, col. 12, ll. 6-14).  Although Simpson teaches that the                          
                addition of liquids (thinners) can be used to lower the temperature needed to                    
                obtain the viscosity necessary for good processing (col. 12, ll. 12-14), there                   
                is no teaching or suggestion in either Simpson or Sartor that such thinners                      
                could be added until the resins were fluid at room temperature.  See                             
                Simpson, col. 13, ll. 42-45.                                                                     
                       For the foregoing reasons and those stated in the Brief, we determine                     
                that the Examiner has not established a prima facie case of obviousness in                       
                view of the reference evidence.  Therefore we cannot sustain the rejection                       
                over Simpson in view of Sartor for claims 1, 2, 4, 5, 10, 11, 13, 16-19, 25,                     
                26, 29, 33-39, 44, 48 and 55-74.                                                                 
                       However, the rejection of claims 41-43, 46, 47, 49 and 50 present a                       
                different issue since these claims do not require that the 100% solids                           
                composition be fluid at room temperature.  As correctly found by the                             

                                                       6
