           Appeal No. 2001-0831                                                                      
           Application No. 08/765,079                                                                

           embodied in appellant’s broadest claim other than the limitation                          
           requiring use of a saturated mono-ol as one of the three                                  
           alcoholic reactants involved in preparation of appellant’s                                
           composition.  Also, we are mindful that Takayama suggests using a                         
           saturated mono-ol as one of two alcoholic reactants to produce                            
           certain urethane compounds, and demonstrates (Table 3) that the                           
           inclusion of a saturated mono-ol is instrumental in avoiding                              
           generation of cracks when producing in-mold cured products.                               
                 That being said, we agree with the appellant that the                               
           differences between the Meixner and Takayama compositions would                           
           appear to be significant, with respect to both the compositions                           
           themselves, e.g., powdery solid (Meixner) v. liquid resin                                 
           (Takayama), and their respective processing characteristics,                              
           e.g., powder coating (Meixner) v. in-mold curing (Takayama).                              
                 Given such differences, in order to establish a nexus                               
           between Meixner and Takayama, and thus a case for obviousness,                            
           the examiner would have to provide evidence or a sound technical                          
           explanation as to why those of ordinary skill in the art would                            
           find the suggestions of Takayama reasonably pertinent to the                              
           particular problems and conditions encountered in the field of                            



                                                 3
